Project Gardens Of The Queen
The Ocean Foundation has recently begun working with partners in the Jardines de la Reina Archipelago, the largest no-take marine preserve in the Caribbean, to focus on research, management and economic issues related to what are considered the most healthy and extensive coral reefs in the Caribbean region. We are working closely with the Cuban Center for Coastal Ecosystems and Marine Research Center of Cuba to better study the natural resources of the region while also assessing their economic and social values.
Project Gardens of the Queen is a comprehensive, aggressive and forward-looking program to research and protect the unique and pristine ecosystems of Jardines de la Reina. This research ensures that these protections will endure in perpetuity, serve as a compelling model for marine protected areas worldwide, dramatically advance human understanding of how healthy coral reef ecosystems function, and yield critical insights to inform management decisions for protecting coral reefs globally.
Furthermore, this ecosystem and educational research model is bringing Americans and Cubans closer together. Former fishermen and their families are now employed in diving and fly fishing operations. Through this they are continually creating human connections by educating visiting ecotourists creating a sustainable way of life; which in turn, is fostering future generations of stewards in this marine park.

“…the majority of catch now derives from the southeast zone, with 44% of the national total. High contemporary catch and CPUE in the southeast zone might be attributable in part to the presence of the Gardens of the Queen Marine Park, the largest and most well-resourced MPA in Cuba. Investment in this MPA has generated higher levels of monitoring and enforcement, ecological recovery, and fishery spillover in this management zone.”

The model of Jardines de la Reina tourism management based on science have proved to be successful and is applied to CZNP. MV OFY (3 environmental advisors, 4 crew) and Avalon (3 dive masters) carried out a fish survey in CZNP coral reef from March 3 to 16 and May 12 to 18, 2018, along Golfo de Cazones region. Visual censuses were carried out in March in 37 sites and Baited Remote Underwater Video (BRUV) were carried out in May in 40 sites during more than 66 hours. Pictures were taken to support fish identification. We group the sites in 6 areas: ETE (Lavandera-Punta Brava), ETW (Punta Brava-Calvario), EC (Cayo Cobo-Cayo Palomo-Ensenada de Cazones), DP (Cayo Diego Pérez), DPS (Faro Diego Pérez-Cayo Sigua), SCB (Cayo Sigua-Cayo Blanco). We recorded large species abundance (sharks, large groupers, large snappers, barracuda, hogfish, eels, rays and turtles) and produced an inventory of fish species. There were recorded 154 fish species. Sharks were observed in four of the six areas: ETE (reef shark, nurse shark), EC (reef shark), DPS (tiger shark), CBS (great hammerhead shark). The gradient of abundance of large animals is CBS>ETE>ETW>DPS>DP>EC, being 2.2 times higher in CBS than in EC. Further data process and research are required to establish the causes of this gradient but it is likely to be related to differential fishing pressure. Large species abundance is up to 3.5 times higher in JRNP than in CZNP which stress the point that actions must be taken for effective enforcement and self-compliance to advance conservation of CZNP.
Long standing effective marine protected areas are rare cases in the conservation practice worldwide. Jardines de la Reina National Park (JRNP) has been protected for more than 20 years, since 1996 as a Marine Reserve and since 2010 as a National Park. The Center for Coastal Ecosystems Research (3 scientists), MV OFY (2 environmental advisors, 4 crew) and Avalon/Marlin (3 dive instructors, 2 skippers) joint efforts to assess JRNP effectiveness between September 23 and October 17, 2017. There were surveyed 24 coral reef drop offs on 8 zones and 15 coral reef crests on 5 zones. Protected coral reef drop offs show 1.7 more large fish (adults reaching more than 40 cm), 3.2 more hogfish (species extremely vulnerable to spearfishing), 2.6 more large jacks and mackerels (adults reaching more than 40 cm), 1.6 more medium size fish (adults reaching less than 40 cm), 2.1 more urchins (keystone species on healthier reef), 1.3 higher coral cover, 1.1 higher fleshy algae cover and similar structural complexity than unprotected coral reef drop offs. Since no large reef crests occur in unprotected zones, the comparison was carried out among central and western zones of the JRNP, being the central zones the best protected ones. Central coral reef crests show 1.5 more large fish, 2.9 more hogfish, 2.1 more large jacks and mackerels, 2.9 more medium size fish, 3.1 more urchins, 4.9 less fleshy algae cover, similar coral cover and 0.8 lower structural complexity than western coral reef crests. Although benthic variables (urchins, algae, corals and structural complexity) require further data process and analysis to assess influence of protection and ecological relationships, the results on several fish groups cannot be explained for any other reason than effective protection of JRNP for over 20 years.
Many species of sharks and rays are endangered worldwide. But little was known of these species in Cuba, particularly about movement pattern and response to marine protected areas. This project started in 2012 as a joint effort among Rachel Graham, former staff of Wildlife Conservation Society and currently managing her own NGO Mar Alliance, and Cuban scientists, two of them currently MV OFY Environmental Advisors. The project has been supported by the Center for Coastal Ecosystems Research and Avalon/Marlin. It is taken place in southeastern Cuba (provinces of Sancti Spíritus, Ciego de Ávila y Camaguey, mainly in Cayos de Ana Maria, islands of the Golfo de Ana Maria and Jardines de la Reina archipelago). There have been carried out ten expeditions setting thousands of set lines on mangroves and dozens of longlines in coral reefs. Results show that there are 2.5-18 times more sharks inside Jardines de la Reina National Park (JRNP) than outside. Taking into account the recapture rate by zones, JRNP offers better protection for the lemon shark (Negaprion brevirostris) and reef shark (Carcharhinus perezii) than for the nurse shark (Ginglymostoma cirratum) and blacktip shark (Carcharhinus limbatus). Seventy-seven percent of recaptured tagged sharks have been taken outside JRNP, mostly by commercial fishermen, an indication of heavy fishing outside the protected area. Economical valuation shows that SCUBA diving with sharks in JRNP contributes with more than $700,000 yearly to Cuban economy. These findings were include in the JRNP 2017 – 2021 Management Plan and in the first National Action Plan for the Conservation of Sharks and Rays in Cuba issued in 2015 and implementation underway.
Whale shark, the largest fish ever exists, is an endangered (IUCN, vulnerable) and highly migratory species that regularly visit favored feeding sites. Sightings of whale sharks in Jardines de la Reina National Park are usually more frequent the last quarter of every year, particularly in November, but they have been absent from it in the last couple of seasons. Since October 30 to December 1, 2017 there were whale sharks sightings every week from one to six individuals per day. They have been part of the assemblage of plankton-silversides-small tunas-silky sharks.
Jardines de la Reina National Park (JRNP) was invaded by lionfish like most of the wider Caribbean places but its current abundance seems to be lower than abroad. The Center for Coastal Ecosystems Research (3 scientists), MV OFY (2 environmental advisors, 4 crew) and Avalon/Marlin (3 dive instructors, 2 skippers) joint efforts to assess lionfish status and the role of natural predators and of humans in the control of this exotic invasive species in JRNP between September 23 and November 30, 2017 and between February 14 to 23, 2018. There were surveyed 24 coral reef drop offs (8-13 m deep and 13-20 m deep) on 8 zones, 46 SCUBA diving sites (13-20 m deep) on 3 zones and 15 coral reef crests on 5 zones. More than 96 % of lionfish were sight on coral reef drop offs 13-20 m deep, more than 91 % were hidden in crevices and overhangs and almost 62 % were in groups of 2 to 4 specimens. These observations might be behavior responses to natural and human predation. The sites hosting 70 % of the potential predators (50 % of all sites) host about 45 % of the lionfish sightings, while the sites hosting 30 % of the potential predators (50 % of all sites) host about 55 % of the lionfish sightings, suggesting than natural predation alone is not enough to control lionfish and that the combination of natural predation and human control, like the one taking place in JRNP, is the key to keep this exotic invasive species in low numbers.
Presence of American crocodile in Jardines de la Reina National Park have been reported for many years and in 2012 there was detected one nest in Cayo Caguamas. Between May 21 and 30, 2019, 12 scientists and research assitants of the Empresa Nacional para la Protección de la Flora y Fauna of 4 provinces carried out an expedition to assess, for the first time, distribution and habitat use of American crocodile in JRNP. There were surveyed by foot from Punta Macao to Boca de Guano to assess coastline features and to detect direct evidence (nests and individuals) and indirect ones (footprints, tracts, shelters). Survey of channels, lagoons by boat and nocturnal surveys were carried out as well. American crocodile occurs at discrete sites from Mexican Channel to a beach in Boca Grande stretching about 70 km. Of the studied sites, only three (beaches at Boca Seca, Boca de Piedra Grande y Boca Grande) showed a combination of proper substrate for nesting and shelter for neonates and juveniles. The other sites have only one of them. There were identified three nesting sites on the beaches of Boca Seca, Boca de Piedra Grande y Boca Grande with one nest detected on each, with evidence that they are used by only one female at a time during the nest season. There were observed five shelters, three footprint and three tracts as well. Two nest were assessed with 33 births, without embryo death nor malformations. Three neonates were caught, measured and tagged. Average size was 26,7 cm. These results must be considered preliminary and do not allow to make abundance estimates nor population trend, for what a higher survey effort is required.
Reproduction is a critical process for all species, particularly for endangered species such as elkhorn coral (Acropora palmata). In August 2017 environmental advisors of MV OFY recorded for the first time in Cuba the spawning of elkhorn coral in JRNP but its magnitude remained unassessed till now. Center for Marine Research of the University of Havana (2 scientists, 3 research assistants and 2 students), Center for Coastal Ecosystems Research (2 scientists) and MV OFY (2 environmental advisors, 4 crew) joint efforts to assess spawning of elkhorn coral for the first time in Cuba, in August 16 to 21, 2019. The selected site was La Puntica crest for its high density and large size of healthy elkhorn colonies and logistic feasibility. Spawning forecast was for the second day of full moon (August 16) but it happened the fourth (August 19) from 9:43 pm to 10:18 pm. Of the four forecast spawning days, it only was observed in one. 21 colonies spawned though gametes were only collected from 4 due to low density of gametes release by the rest of the colonies. The gametes collected were mixed onboard and after two hours fertilization was detected. Adtionally, six reef crest sites were sampled. There are a high number of fragments young elkhorn colonies oversheeting old-mortality colonies. Prevalence of diseases and bleaching was low.
Jardines de la Reina National Park and surroundings coral reefs were surveyed between March 3 and 21, 2019. Center for Coastal Ecosystems Research (3 scientists), Center for Marine Research of the University of Havana (3 scientists and 4 research assistants), Center for Fisheries Research (3 scientists) and MV OFY (3 environmental advisors, 6 crew) joint efforts to surveyed 44 sites (25 reef drop offs / spur and grooves and 19 reef crests) in 9 zones (7 inside the National Park and 2 outside of it). For the first time were surveyed spiny lobster and sea cucumber. Preliminary, fish are more abundant inside the National Park, coral density is similar inside the National Park than outside, sea cucumbers are scarce in all coral reefs, spiny lobsters are more abundant outside the National Park and most of the female lobsters were ripped.
Jardines de la Reina National Park winter 2019 marine turtles monitoring Report
Jardines de la Reina National Park is the only place in Cuba where three species of marine turtles show a positive trend of nesting but last monitoring was carried out in 2016. National Enterprise for the Conservation of Flora and Fauna (seven scientists and research assistants), Center for Coastal Ecosystems Research (two research assistants), MV OFY (3 crew) and Avalon/Marlin (two environmental advisors) joint efforts to carry out between January 25 and February 7, 2019, the first monitoring of marine turtles since 2016. There were surveyed 32 beaches along the whole archipelago, covering more than 39 km. There were detected 236 nests of hawksbill turtle and 683 nests of green turtle. There were assessed 159 nests of hawksbill turtle and 147 nests of green turtle. There were deployed four temperature loggers on two nests (one in the nest and one out of it) on Caballones East beach for monitoring incubation temperature. Although data require further process and analysis, it is evident that Jardines de la Reina National Park continues being the only place in Cuba where these species of marine turtles show a positive trend of nesting thanks to its effective protection.
Jardines de la Reina National Park (JRNP) Deep Coral Reef Baited Remote Underwater Video (BRUV) Survey Report
Baited Remote Underwater Video (BRUV) is a research method particularly good for assessing the abundance of sharks, keystone species heavily depleted around the world. It is also good to survey deeper environments, where safe SCUBA diving bottom time limits visual censuses. MV OFY (3 environmental advisors, 4 crew) used, for the first time ever, this method to assess large species abundance in JRNP deep coral reef (shelf border, 20 – 30 m deep) from April 20 to 28, 2018. There were surveyed 75 sites during more than 147 hours along JRNP. Besides sharks, we recorded other large species (large groupers, large snappers, barracuda, hogfish, eels, rays and turtles). There are up to 1.6 times more large animals inside the protection than in fishing grounds. In the case of sharks, there were up to 6.8 times more inside the protection than in fishing grounds. These findings cannot be explained for any other reason than the effective protection of JRNP for over 20 years.
Workshop to Advance Monitoring and Research in Jardines de la Reina National Park Report
Reina National Park (JRNP) between December 9 and 14, 2018. We gathered several Cuban institutions relevant to conservation and science in JRNP: eight scientists, officials and field assistants of the National Enterprise for the Protection of Flora and Fauna (JRNP administrator); six scientists and officials of the Center for Coastal Ecosystems Research; four scientists and officials of the Center for Marine Research of the University of Havana; four scientists of the Center for Fisheries Research and seven environmental advisors and crew of MV OFY and Avalon. On Sunday 9 we navigated to JRNP. We briefed about MV OFY programs and features and about the knowledge gathered for more than 20 years of work in Jardines de la Reina archipelago. On Monday 10 we exchanged about the 2017 – 2021 management plan and conservation targets (American crocodile, mangrove ecosystem, marine turtles, coral reef ecosystem, large groupers, gamefish, sharks and rays) and discussed about American crocodile and mangrove ecosystem monitoring and research activities. Field visits were carried out in tourism facilities at Nicola’s channel, mangrove channel, seagrass, coral heads and fore reef crest. On Tuesday 11 we discussed about marine turtles, coral reef ecosystem, fisheries, large groupers, gamefish, sharks and rays monitoring and research activities. Field visits were carried out in reef crest channel, reef slope and sighting silky sharks. On Wednesday 12 we worked on monitoring and research proposals for the conservation targets and timeframe for 2019. Field visits were carried out in fore and back reef crest, coral reef lagoon, island channel, seagrass and reef slope. On Thursday 13 we worked on monitoring and research proposals for the conservation targets and timeframe for 2019. Field visits were carried out in fore reef crest, island channel and seagrass. On Friday 14 the workshop was close and participants returned their homes.
Jardines de la Reina National Park (JRNP) Effect on Large Parrotfishes Protection Report
Grazing is a key ecological process in tropical coral reef ecosystems. The Center for Coastal Ecosystems Research (2 scientists, 2 research assistant), MV OFY (2 environmental advisors, 4 crew) and Avalon/Marlin (1 dive instructor) joint efforts to assess, for the first time ever, JRNP effectiveness on large parrotfishes (rainbow and midnight parrotfishes) protection and their grazing behavior between January 8 to 18 and between February 22 and 23, 2018. There were surveyed 42 coral reef sites from 5 to 20 m on 2 zones, inside the National Park and outside it. There are 5.4 times more large parrotfishes inside and they are bigger inside too (59 % of fishes are bigger than 50 cm inside the protection vs 33 % outside). Grazing intensity is 1.6 times higher inside than outside. Although these findings require further data process and analysis to assess influence of protection and ecological relationships, it is likely the results cannot be explained for any other reason than effective protection of JRNP for over 20 years.
Elkhorn & Staghorn corals survey in Jardines de la Reina National Park Report
Up to 85 % of wave energy can be reduced by reef crest, once dominated by Elkhorn coral, currently an endangered species as its relative Staghorn coral. A comprehensive survey of Elkhorn/Staghorn corals was carried out in Jardines de la Reina National Park (JRNP), Cuba, between August 27 and October 15, 2017, in order to assess species status and distribution patterns. The Center for Coastal Ecosystems Research (5 scientists, 5 research assistants), MV OFY (2 environmental advisors, 4 crew) and Avalon/Marlin (2 dive instructors) joint efforts to survey 100 % of the 91 km of suitable habitat for these species in JRNP. During the survey almost 7 300 colonies were recorded (about 7 000 of Elkhorn coral). About 100 Elkhorn coral thickets and 3 600 fragments of Elkhorn coral were recorded as well. Elkhorn coral thickets will be the focus for conservation and monitoring efforts. 96 % of the colonies, 94 % of the thickets and almost 100 % of the fragments are located in the western half of JRNP. More than half of the colonies rank in “good” and “very good” condition, an indicator of a healthy population. This is only the second survey of its kind in the Western Atlantic and the largest one (previous covered 7 km). See Hernandez – Fernandez et al 2019 peer reviewed paper for more detailed analysis.
Fall 2018 Terrestrial Monitoring in Jardines de la Reina National Park Report
Terrestrial monitoring of the raining season was carried out in seven islands of Jardines de la Reina National Park (JRNP) (Grande, Caballones, Anclitas, Piedra Grande, Cachiboca, Caguama and Cabeza del Este). The monitoring includes flora and vegetation, mollusks, arachnids, insects, reptiles, birds and, for the first time, qualitative assessment of beaches. The Center for Coastal Ecosystems Research and Center for Environmental Research of Camagüey (8 scientists, 3 research assistants), MV OFY (1 environmental advisor, 4 crew) and Avalon/Marlin (1 skipper) joint efforts to carried out this monitoring between September 22 to 26, 2018. For the first time was recorded permanent small-leave forest in JRNP in cayos Cachiboca and Grande and two new records of plants for cayos Grande and Anclitas. Beaches show escarps as a sign of erosion by natural causes in all islands but cayos Cachiboca and Cabeza del Este where gentle slope occur.
Goliath grouper (Epinephelus itajara) Research and Conservation in Cuba Report
Goliath grouper, Epinephelus itajara, is a giant fish that can grow to 800 pounds and had nearly disappeared by the 1970s due primarily to overfishing. But little was known of this species in Cuba. This project was the Pew Fellowship on Marine Conservation of MV OFY Environmental Advisor Fabian Pina Amargos carried out from 2012 to 2015 supported by the Center for Coastal Ecosystems Research and Avalon/Marlin. It took place in southeastern Cuba (provinces of Sancti Spíritus, Ciego de Ávila y Camaguey, mainly in Cayos de Ana Maria, islands of the Golfo de Ana Maria and Jardines de la Reina archipelago). There were carried out ten expeditions setting thousands of set lines on mangroves; handline hundreds of hours on spawning aggregation sites and SCUBA dives dozens of hours on spawning aggregation sites. All information is first of its kind in Cuba. There was confirmed the existence of one spawning aggregation site, the first detected by science in Cuba. Goliath grouper was more abundant inside Jardines de la Reina National Park than outside, but its density was very low, probably due to fishing at the spawning aggregation site. Although the Goliath grouper did not constitute an important fishery in Cuba, there was caught commercially during the spawning season and for subsistence year-round. The only fishing regulation was a weight limit of 960 grams. More than 20 years ago, fishing for Goliath grouper generally took place in shallower waters, which probably indicates the impact of fishing in species depth distribution. Based on these findings it was recommended that Goliath grouper fishing be banned in the spawning aggregation site found in Jardines de la Reina during July, August, and September, and that a minimum legal size of 110 cm be established. It was also recommended a ban on spearfishing of Goliath grouper in Cuban waters. The Cuban government went a step further: Consensus was built among the stakeholders and Resolution 178/2018 was passed to fully protect goliath grouper in Cuban waters.
Jardines de la Reina National Park hurricane boulder deposit Report
Boulder deposits in Caribbean coastal areas have been studied, mainly to answer to their controversial origin: paleohurricanes or paleotsunamis? The answer of this question is relevant for risk analysis in the face of climate change. There are several areas with boulder deposits in Cuba; some of them are huge and named as megablocks. In the southern coast of the Jardines de la Reina National Park (JRNP), boulder deposits occur as well. The Center for Coastal Ecosystems Research (1 scientist, 1 research assistant), MV OFY (1 environmental advisor, 4 crew) and Avalon/Marlin (1 skipper) joint efforts to assess quantitatively boulder deposits in JRNP between August 24 September 6, 2018. Boulder deposits are in the central region of JRNP stretching from the eastern most part of Cayo Grande to the Cayo Cachiboca lighthouse. The largest megablock is located in Cayo Boca de Piedra which weight has been estimated over one hundred tons. Preliminary analysis suggests paleohurricanes waves as the force that deposited these boulders in JRNP.
Photo ID of marine turtles in feeding grounds of Jardines de la Reina National Park
Jardines de la Reina is the largest marine reserve of the Caribbean and hosts many keystone species for Cuban archipelago marine biological diversity, including marine turtles. This research used photo ID of these species in Jardines de la Reina National Park (JRNP) feeding grounds. Noel López Fernández (Avalon), Fabián Pina Amargos (MV OFY) and Tamara Figueredo Martin (MV OFY) compiled 284 photos taken in SCUBA diving sites of JRNP between 2010 and 2016 analysed by Julia Azanza Ricardo (Instituto Superior de Tecnología y Ciencias Aplicadas). A total of 47 individuals were photo ID: 44 hawskbill turtles (Eretmochelys imbricata) and 3 loggerhead turtles (Caretta caretta). They were sighted 54 times. The highest frequency of sightings were in 2012 with 20 and 2011 and 2014 with 8 each one. It was possible to photo re-ID seven individuals, one of them twice in 2013. Average time between sightings was 2,5±1,6 years (min,: 1 year; max.: 5 years). Results show is possible to follow up JRNP marine turtles in feeding grounds using photo ID, becoming a valuable tool for the conservation in marine protected areas.
Spring 2018 Terrestrial Ecosystems Monitoring of Jardines de la Reina National Park Report
Jardines de la Reina National Park (JRNP) has been protected for more than 20 years, since 1996 as a Marine Reserve and since 2010 as a National Park. This National Park not only protects marine ecosystems and biota, but terrestrial ones as well. The Center for Coastal Ecosystems Research (4 scientists and 2 research asistants), the Center for Environmental Research of Camaguey (4 scientists) and MV OFY (2 environmental advisors, 3 crew and 1 skipper) joint efforts to monitor JRNP terrestrial ecosystems on April 8 to 17, 2018. Additionally, there were assessed the health condition of 113 mangroves sites (89 alive and 24 death) to study the mortality of this ecosystem in the area. There were surveyed 8 islands spread in the entire archipelago. There was record a new species of plant for the archipelago at the east of Cayo Caballones. Species richness of mollusks was low in general but there were recorded 3 new species for the archipelago. The highest densities of mollusks were found in Cayo Caguamas and the lowest in Cayo Grande. The islands with highest abundance of lizards were Caballones and Caguama. There were recorded 2 new species of lizards for the archipelago in Cayo Caballones. Although data require further process and analysis, experts believe terrestrial ecosystems and biota in the Park remain stable.
Jardines de la Reina National Park Summer 2018 Effectiveness on Seagrass Protection Report
Long standing effective marine protected areas are rare cases in the conservation practice worldwide. Jardines de la Reina National Park (JRNP) has been protected for more than 20 years, since 1996 as a Marine Reserve and since 2010 as a National Park. The Center for Coastal Ecosystems Research (4 scientists, 1 research assistant), MV OFY (2 environmental advisors, 4 crew) and Avalon/Marlin (1 dive instructor) joint efforts to assess JRNP effectiveness on seagrass protection between June and July, 2018. There were surveyed 16 seagrass sites on 8 zones, assessing seagrass and its associated large fish. Seagrass coverage were about 50 % of turtle and manatee grass and calcareous algae with up to around 600 plants/m2. Main epiphytes algae on seagrass were crustose ones. Water temperature, salinity and pH were the usual ones for the season. Large fish were surveyed using Baited Remote Underwater Video. Protected seagrass show 2.4 more large fish (adults reaching more than 40 cm) than unprotected seagrass. On species level, protected seagrass show 2.1 times more jacks and mackerels (adults reaching more than 40 cm) than unprotected seagrass. Fish species richness is also higher in protected than unprotected seagrass (15 species vs 5). Although seagrass variables require further data process and analysis to assess influence of protection and ecological relationships, these results are consistent with those of the winter 2017 survey and it is likely the results cannot be explained for any other reason than effective protection of JRNP for over 20 years.
Tropical storm Nate impact on Jardines de la Reina National Park coral reef crests Report
Tropical storms are well known to severely impact coral reef. Tropical storm Nate big waves hit Jardines de la Reina National Park (JRNP) from October 5 to 7, 2017. The Center for Coastal Ecosystems Research (3 scientists), MV OFY (2 environmental advisors, 4 crew) and Avalon/Marlin (1 dive instructors) joint efforts to assess Tropical storm Nate impact on JRNP coral reef crests. From October 10 to 15 there was surveyed 21 % of the almost 7 000 colonies of Elkhorn coral of JRNP, an endangered species of branching coral, highly susceptible to tropical storm damage. Just 3.4 % of them were damaged, most of them with few broken branches. Taking into account this figure it can be concluded that Tropical storm Nate had an extremely low impact on JRNP coral reef crests. Further studies are needed to assess whether this resilience is due to the healthy condition of JRNP coral reef.
Jardines de la Reina National Park Winter 2017 Effectiveness on Seagrass Protection Report
Long standing effective marine protected areas are rare cases in the conservation practice worldwide. Jardines de la Reina National Park (JRNP) has been protected for more than 20 years, since 1996 as a Marine Reserve and since 2010 as a National Park. The Center for Coastal Ecosystems Research (4 scientists, 1 research assistant), MV OFY (2 environmental advisors, 4 crew) and Avalon/Marlin (1 dive instructor) jointed efforts to assess, for the first time ever, JRNP effectiveness on seagrass protection between December 2 to 15, 2017. There were surveyed 16 seagrasses sites on 8 zones, assessing seagrass and its associated large fish. Seagrass coverage were about 50 % of turtle and manatee grass and calcareous algae with up to around 600 plants/m2. Main epiphytes algae on seagrass were crustose ones. Water temperature, salinity and pH were the usual ones for the season. Large fish were surveyed using Baited Remote Underwater Video for the first time in JRNP. Protected seagrasses show 3.4 more large fish (adults reaching more than 40 cm) than unprotected seagrass. On species level, protected seagrasses show 5.2 times more great barracudas and 7 times more jacks and mackerels (adults reaching more than 40 cm) than unprotected seagrass. Fish species richness is also higher in protected than unprotected seagrasses (21 species vs 13). Although seagrass variables require further data process and analysis to assess influence of protection and ecological relationships, it is likely the results cannot be explained for any other reason than effective protection of JRNP for over 20 years.
Winter 2017 Terrestrial Ecosystems Monitoring of Jardines de la Reina National Park Report
Jardines de la Reina National Park (JRNP) has been protected for more than 20 years, since 1996 as a Marine Reserve and since 2010 as a National Park. This National Park not only protects marine ecosystems and biota, but terrestrial ones as well. The Center for Coastal Ecosystems Research (5 scientists and 3 research asistants), MV OFY (2 environmental advisors, 4 crew) joint efforts to monitor JRNP terrestrial ecosystems on November 4 to 17, 2017. There were surveyed 6 islands spread in the entire archipelago, including Cachiboca, Caballones and Boca de Piedra Grande for the first time ever. From the terrestrial vegetation point of view, Caballones is the island with the highest species richness of plants where Erithalis fruticosa is the most abundant one. Vegetation covers an average of 40 % of the islands surface. The endemic species Coccothrinax littoralis are found abundant in all of the islands. Insects and arachnid abundance are low, except for Boca de Piedra Grande. In case of mollusk two genera were record with prevalence of Cerion, with patched distribution from cero to more than one thousand individuals per sample. Caguama is the island with highest abundance and mortality of mollusk, an apparent contradiction that requires further research. Caguama also is the island with the highest abundance of iguanas. Another reptile, Green Anoles (Anolis allisoni, introduced species) shows a broader distribution in Caguama than in previous surveys. In general, abundance of reptiles increases from previous surveys during the same weather season. 52 birds species were detected, two of them are new records of birds for the Jardines de la Reina Archipelago. Aquatic birds represent 58 % of species recorded. Brown Pelican (Pelecanus occidentalis), Double-Crested Cormorant (Palacrocorax auritus) and Palm Warbler (Setophaga palmarum) are the more abundant birds. Although data require further process and analysis, experts believe terrestrial ecosystems and biota in the Park remain stable.
Coral reef ecosystems are seriously threatened by changing conditions in the ocean. Although many factors are implicated, climate change has emerged as a dominant and rapidly growing threat. Developing a long-term strategic plan for the conservation of coral reefs is urgently needed yet is complicated by significant uncertainty associated with climate change impacts on coral reef ecosystems. We use Modern Portfolio Theory to identify coral reef locations globally that, in the absence of other impacts, are likely to have a heightened chance of surviving projected climate changes relative to other reefs. Long-term planning that is robust to uncertainty in future conditions provides an objective and transparent framework for guiding conservation action and strategic investment. These locations constitute important opportunities for novel conservation investments to secure less vulnerable yet well-connected coral reefs that may, in turn, help to repopulate degraded areas in the event that the climate has stabilized.
Cuba (E) is one of the examples of sites that perform relatively well in Figure 2. It is among 23 % of the best reef.
“…balanced solution includes reefs in 31 of the 87 countries that have more than 500 km2 of tropical coral reefs, with multiple BCUs in countries such as Australia, Cuba, French Polynesia, Philippines, Bahamas, and Malaysia (Figure 4).”
Figure 4 show Jardines de la Reina is one of the reef to show balanced scenario (represents the optimal portfolio presented in this paper).

Alcolado Menéndez (2019): Ecological condition of coral reef assemblages in the Cuban Archipelago, Marine Biology Research, DOI: 10.1080/17451000.2019.1577557
The condition of coral reefs in the Cuban Archipelago is poorly known. We aimed to analyse coral assemblages across 199 reef sites belonging to 12 localities. Crest and fore reefs were assessed using six metrics: species richness, density, coral cover, mortality, coral size and reef complexity. The condition of reefs varied across the archipelago from healthy to depleted reefs. The localities with best scores were Cienfuegos, Bahía de Cochinos and Cazones. These reefs have values of living coral cover (>20%) and complexity (>50 cm) similar to the best preserved Caribbean reefs. However, the majority of crest biotopes suffered important deterioration with old mortality of Acropora palmata populations and moderate coral cover (15%); although crest reefs still maintained their structural complexity. Despite moderate levels of coral cover in fore reefs (18%), their condition was alarming because 25% of the sites had cover below the recovery threshold of 10%, accumulated mortality and structural flattening. Compared with the 1980s, the species richness was roughly the same (42) for crest and fore reefs, although dominance has changed to widespread tolerant species. Coral reef assemblages varied at local and regional scales in similar magnitude, suggesting the combined effects of natural and anthropogenic drivers.
“…and Jardines de la Reina had the highest values of coral cover.”
“The lowest values of mortality occurred in Cienfuegos and Jardines de La Reina.”

Caribbean coral reefs are biodiversity-rich habitats which provide numerous ecosystem services with both ecological and economical values, but nowadays they are severely degraded. In particular, populations of the major framework-building coral Orbicella faveolata have declined sharply, and therefore, understanding how these threatened coral populations are interconnected and how demographic changes have impacted their genetic diversity is essential for their management and conservation. Previous population genetic surveys showed that gene flow in this species is sometimes locally restricted in the Caribbean; however, little genetic data are available for Cuban populations. Here, we analyzed the variation at the mitochondrial DNA control region and six microsatellite loci from O. faveolata colonies from five distant localities representing most of the main coral reefs around Cuba. Both genetic markers showed evidence of genetic differentiation between the northwestern area (Colorados Archipelago) and the other reefs. Colonies from the Colorados Archipelago harbored the largest number of unique mtDNA haplotypes and microsatellite alleles, which suggests long-term large population size or gene flow from other areas of the Caribbean. These results indicate that the Colorados Archipelago area is particularly important for O. faveolata populations and it is well suited for reef management and restoration efforts.

Within the marine studied groups at Jardines de la Reina National Park (PNJR) there are corals and sea urchins, with data references since 1980 and 2011, respectively. At his study, we describe the first records that a Cuban scientific institution made to an Ocean Biogeographic Information System (OBIS). These reports were of coral and sea urchins species identified in situ from field sampling at September of 2015 and February of 2016 and 2017 at PNJR. For the corals study were placed 10 transects per site, every one of 10 m of large to cover 140 transect; 20 transects were placed at shallow scarp at the rest were placed at reef crests. For the sea urchin census 10 band transects per site were placed at reef crests (60), of 10 m long x 1 m width. One hundred and sixty-five records of 28 species of corals were made, 20 for the shallow scarp habitat and 19 for the reef crests. Six species of sea urchins were identified. The whole register have been added to the OBIS database, in order to update the information presented in this worldwide marine species database, which until now none Cuban contributions has been reported. Both the information of corals and sea urchins from PNJR given to OBIS begin the contribution of Cuban scientific institutions to this platform, which provides a base of scientific knowledge about global data, in issues of diversity, distribution and abundance of marine organisms in standardized format.
García–Quintas, A. & Parada Isada, A., 2017. Underlying factors promoting nestedness of bird assemblages in
cays of the Jardines de la Reina archipelago, Cuba. Animal Biodiversity and Conservation, 40.1: 7–16,
Assessing the factors associated with nestedness patterns is a crucial aspect in studies of community structure. Bird assemblages in the Jardines de la Reina archipelago have a stable nested structure but the underlying inﬂuences have not been evaluated. We constructed a presence–absence data matrix based on a bird inventory obtained from 43 cays of this archipelago. We calculated nestedness using the NODF metric based on the overlap and decreasing fill and evaluated its significance by running 1,000 iterations of four null models. The matrix columns were rearranged to evaluate seven factors possibly related to the nestedness of bird communities. Bird assemblages exhibited a significant nested pattern (67.93) and all factors contributed (p < 0.01) to the nestedness patterns of bird communities. Habitat diversity and cay area and perimeter were the factors that contributed most to the nested structure. The nestedness pattern in the bird assemblages of the Jardines de la Reina archipelago was potentially caused by the interaction of selective extinction and differential colonization of species, with the former having a more remarkable effect.z
Episodes of mass coral bleaching have been reported in recent decades and have raised concerns about the future of coral reefs on a warming planet. Despite the efforts to enhance and coordinate coral reef monitoring within and across countries, our knowledge of the geographic extent of mass coral bleaching over the past few decades is incomplete. Existing databases, like ReefBase, are limited by the voluntary nature of contributions, geographical biases in data collection, and the variations in the spatial scale of bleaching reports. In this study, we have developed the first-ever gridded, global-scale historical coral bleaching database. First, we conducted a targeted search for bleaching reports not included in ReefBase by personally contacting scientists and divers conducting monitoring in under-reported locations and by extracting data from the literature. This search increased the number of observed bleaching reports by 79%, from 4146 to 7429. Second, we employed spatial interpolation techniques to develop annual 0.04˚ × 0.04˚ latitude-longitude global maps of the probability that bleaching occurred for 1985 through 2010. Initial results indicate that the area of coral reefs with a more likely than not (>50%) or likely (>66%) probability of bleaching was eight times higher in the second half of the assessed time period, after the 1997/1998 El Niño. The results also indicate that annual maximum Degree Heating Weeks, a measure of thermal stress, for coral reefs with a high probability of bleaching increased over time. The database will help the scientific community more accurately assess the change in the frequency of mass coral bleaching events, validate methods of predicting mass coral bleaching, and test whether coral reefs are adjusting to rising ocean temperatures
Figure 4 shows that Jardines de la Reina had low impact/probability of bleaching in 2005, a year with a strong bleaching event worldwide.

Global coral reef related tourism is one of the most significant examples of nature-based tourism from a single ecosystem. Coral reefs attract foreign and domestic visitors and generate revenues, including foreign exchange earnings, in over 100 countries and territories. Understanding the full value of coral reefs to tourism, and the spatial distribution of these values, provides an important incentive for sustainable reef management. In the current work, global data from multiple sources, including social media and crowd-sourced datasets, were used to estimate and map two distinct components of reef value. The first component is local “reef-adjacent” value, an overarching term used to capture a range of indirect benefits from coral reefs, including provision of sandy beaches, sheltered water, food, and attractive views. The second component is “on-reef” value, directly associated with in-water activities such diving and snorkelling. Tourism values were estimated as a proportion of the total visits and spending by coastal tourists within 30 km of reefs (excluding urban areas). Reef-adjacent values were set as a fixed proportion of 10% of this expenditure. On-reef values were based on the relative abundance of dive-shops and underwater photos in different countries and territories. Maps of value assigned to specific coral reef locations show considerable spatial variability across distances of just a few kilometres. Some 30% of the world’s reefs are of value in the tourism sector, with a total value estimated at nearly US$36 billion, or over 9% of all coastal tourism value in the world’s coral reef countries.
Figure 2 shows that economic value of Jardines de la Reina coral reef for tourism is from high to very high ($356,000 km-2 yr-1).
Valdivia A., C. E. Cox, J. F. Bruno, 2017. Predatory fish depletion and recovery potential on Caribbean reefs. Sci. Adv. 3, e1601303
The natural, prehuman abundance of most large predators is unknown because of the lack of historical data and a limited understanding of the natural factors that control their populations. Determining the supportable predator biomass at a given location (that is, the predator carrying capacity) would help managers to optimize protection and would provide site-specific recovery goals. We assess the relationship between predatory reef fish biomass and several anthropogenic and environmental variables at 39 reefs across the Caribbean to (i) estimate their roles determining local predator biomass and (ii) determine site-specific recovery potential if fishing was eliminated. We show that predatory reef fish biomass tends to be higher in marine reserves but is strongly negatively related to human activities, especially coastal development. However, human activities and natural factors, including reef complexity and prey abundance, explain more than 50% of the spatial variation in predator biomass. Comparing site-specific predator carrying capacities to field observations, we infer that current predatory reef fish biomass is 60 to 90% lower than the potential supportable biomass in most sites, even within most marine reserves. We also found that the scope for recovery varies among reefs by at least an order of magnitude. This suggests that we could underestimate unfished biomass at sites that provide ideal conditions for predators or greatly overestimate that of seemingly predator-depleted sites that may have never supported large predator populations because of suboptimal environmental conditions.
“…average total fish biomass per site (mean ± SE) ranged from~55 ± 8 g m-2 at Mexico Rocks in Belize to ~445 ± 148 g m-2 at El Peruano inside the Gardens of the Queen marine reserve in Cuba (Fig. 1).”
“…total predatory fish biomass at sites within the marine reserves of Gardens of the Queen in Cuba and Dry Tortugas in Florida showed predatory fish biomass within values predicted by the models…”
Gardens of the Queen 4 sites are among the top 9 sites of highest biomass of the 39 sites surveyed in the Caribbean (see Figure 1).
Gardens of the Queen 4 sites are among the top 9 sites of highest estimated biomass of predatory reef fish in the absence of human activities of the 39 sites surveyed in the Caribbean (see Figure 3).
Gerhartz-Abraham A., Lucia M. Fanning, Jorge Angulo-Valdés. 2016. ICZM in Cuba: Challenges and opportunities in a changing economic context. Marine Policy 73: 69–76.
Cuba embraced integrated coastal zone management (ICZM) after the Earth Summit, 1992. A series of legal and institutional arrangements rapidly emerged, creating a more solid framework for ICZM in the Caribbean island. Nonetheless, although nearly 48% of Cuba jurisdictional area is ocean, the scope of most ICZM initiatives in the country has been limited to coastal terrestrial issues. Thus, recognition for the inclusion of the marine component of the coastal zone in the national policies and legislation for ocean and coastal management is needed. This paper discusses a number of policy and legal shortcomings that constrain integration and success in ICZM initiatives. Such limitations coupled with opportunities arising from the current political and economic context in the island put the realization of successful ICZM at risk. Overall, the development of a new and comprehensive policy that supports integrated coastal and ocean management in Cuba is critical for: i) addressing the gaps and limitations of the national ICZM approach; and ii) addressing the imminent challenges and opportunities that the new Cuban economic model may represent to the national governance of ICZM.

The study was accomplished at the beginning of December of 2008. The ecological density, use of the substratum and aggregation were determined by individuals’ count at circular 1m2 plots of land, in Cayo Anclitas (Anclita I and Anclita II), Cayo Cachiboca, and in Cayo Caguamas. The ecological density of Cerion santacruzense varied between the different localities, the bigger value was registered in Cayo Caguamas, 24,5 (7 – 56 indiv/m2) and minor in Cayo Anclita I, 0,7 (0 – 13indiv/m2). The four studied populations had an aggregate distribution The riche of used plants as the substrate was fall, predominating the use of plants herbaceous, principally the grass Schizachyrium gracile. Substrates more used were grasses (Gramineae), branches and trunks principally. Regarding the strata it was characterized to use the lowest (0,1 – 0,5 m), in the which, 84% of the specimens were detected.

Cyclura nubila nubila is an endemic subspecies of Cuba and it has been listed as Vulnerable in the IUCN Red List. The present investigation was developed in November 2013 and February 2014 in Caguamas and Palomo cays, respectively. Thirty-seven fecal pellets were collected through fixed transects on sandy coast vegetation and subsequently moistened with water and alcohol to separate and identify diet‘s components. Nine species of plants in Caguamas and four in Palomo were identified as part of iguana‘s diet. The most frecuent plant species were Conocarpus erectus, Setaria parviflora and Thalassia testudinum in Palomo and Cochorus hirsutus in Caguamas. In Palomo 45% of fecal pellets contained corporal parts of dragonflies and 5% parts of crabs. The consumption of animal matter is due to the low floristic diversity of Palomo cay. The iguana‘s diet in Caguamas included more plant components mainly fruits. This study contributes to increase knowledge of trophic ecology and management of the species in the archipelago of Jardines de la Reina

Four of coral reef crests were sampled in the Jardines de la Reina National Park, Cuba, to know their condition in February 2016.Ecological indicators on the Scale System for the Classification and Score of Benthos and Fish Fauna Condition of Coral Reefs in Cuba and the Greater Caribbean were evaluated. The predominant species of corals were, in descending order, Porites astreoides, Millepora complanata and Acropora palmata. Diadema antillarum urchins were predominant and Echinometra lucunter lucunter. The macroalgae with the most abundance were Halimeda opuntia and Canistrocarpus cervicornis. The coral covers was similar in most of sampling sites, but in Anclitas (Site 1), lower density of D. antillarum and less coverage of the species A. palmata was reported. However, in La Puntica site higher density D. antillarum and greater coverage A. palmata was found. The latter site was also the highest percentage of crustose macroalgae even when no significant differences with the remaining sites were found. The latter was also the highest percentage of crustose macroalgaes was determined, although no significant differences with the remaining sites. Anclitas key crest was classified as “unhealthy”, the Caballones key crest: Bayamesa y Caballones as “less healthy”, whereas that La Puntica as “healthy”. The status of coral reef crest of Jardines de la Reina National Park, as crucial element to be defined, as the nutrient composition and direction of tidal currents as well as the community of herbivorous fish.

The research goal was to evaluate the health reef in a sector of the National Park Jardines de la Reina (PNJR) and the Golfo de Ana María (GAM). Four stations were established in to the PNJR and two in GAM on February of 2015. The selected biotopes were terrace border and coral patch. The selected ecologic indicators to evaluate the reef’s health were: coral health, coral density and the most abundant species, as well as coral, algal and sponge cover. To evaluate the health and density was used the belt transect method with 10 m long for 1 m of wide, and for the cover it was used the 10 m long lineal transect. Ten sample units for stations were placed. Coral health was affected mainly by bleaching (17.7% of bleached colonies). The most affected due to the blanching were Siderastrea siderea (Ellis y Solander, 1786) y Agaricia agaricites (Linnaeus, 1758). Yellow blotch disease affected to Orbicella annularis (Ellis y Solander, 1786). Old mortality mainly affected to O. annularis y O. faveolata (Ellis y Solander, 1786). Coral density varied between 35.2 colonies/10 m2 and 92.2 colonies/10 m2. Porites astreoides (Lamarck, 1816) was the specie that showed highest density. Live coral cover varied between 9% and 55%.The results permit conclude that even though the Marine Protected Areas aren’t invulnerable to global impacts, the ecological indicators evaluated and related with health, density and coral cover shows better results than for others Cuban and Caribbean reefs.

Variability in environmental conditions and ocean currents can influence population connectivity and the exchange of larvae among locations. This is especially true for species that spawn in aggregations during a limited temporal window, such as many of the commercially and ecologically valuable species of snapper (Lutjanidae) in Cuba. Biophysical modeling has been used for over a decade to describe the pelagic pathways, sources, and sinks of lutjanid larvae. Here, we build on earlier studies by incorporating more advanced modeling techniques, higher resolution oceanography, and an expanded temporal scope using circulation from 2004 to 2013. Our goal was to revisit the relative linkages of Cuban snapper larvae among regions of the Cuban shelf and neighboring countries by investigating their interannual variability and spatial patterns. Biophysical simulations suggest the majority of larvae produced from snapper spawning aggregations are retained on-island, often within the region where they were spawned, with the exception of an aggregation in northwest Cuba. We used multinomial logistic regression to identify consistency in patterns of simulated biophysical larval transport, and to determine the number of years of simulation required to approximate connectivity. The best fit model correctly identified major connections from each spawning location to greater Caribbean destinations for each species. However, connections at smaller spatial scales were less predictable, and variance increased if fewer years of larval transport were considered. While the magnitude of settlement varies annually, the spatial arrangement of connectivity is relatively consistent such that modeled pathways from spawning aggregations can effectively inform connectivity planning, such as the placement of spawning reserves.
“…for SE Cuba, mean Cuban settlement was 52% (2 to 99%) and mean Jamaican settlement was 6% (0 to 51%)…”

Colonialism is one of the more conspicuous reproduction characteristics of the most waterbirds species. This phenomenon constitutes an important adaptation that benefits the colonies reproduction. National Park Jardines de la Reina is included into one of the more isolated and conserved archipelago of Cuba. Knowledge about waterbirds ecology in this zone is low despite what it have great potentialities to shelter colonial reproduction sites. I conducted an extensive search of waterbirds reproductive colonies in May 2012 and described these by mean of its specific composition and characteristics of the nests and eggs. I registered 31 reproductive colonies of six birds species. Except for Charadrius wilsonia, vegetation where were located the nests was the mangroves forests. Measures of nests and eggs of sampled species were similar to the values registered on the literature. Only clutch size of Pelecanus occidentalis was lower than other works. I considered what the number of colonies registered in Jardines de la Reina is subestimated, and I highlighted the needed of increasing investigations about the waterbirds ecology.

Scuba diving is one of the main activities in the Jardines de la Reina National Park (PNJR), located oﬀ the southern coast of Sancti Spiritus, Ciego de Avila and Camagüey provinces. This study was conducted to determine the eﬀect of this activity on the coral reefs of the area, particularly on stony corals. A total of 28 sites were surveyed during a ten-day period. Areas with high, medium, and low diving intensity, as well as no diving were compared taking into account the percentage of stony coral cover. A total of 220 line transects were used and 51 divers were observed. In sites with high diving intensity, 36 species of stony corals were identified, mostly including S. siderea, A. agaricites, P. astreoides, M. alcicornis and O. faveolata. Of the 51 divers observed, 48 violated diving regulations such as making contact with the corals, sediment suspension, and, to a lesser degree, mechanical damage (breaking of organisms). Gorgonians, followed by stony corals, were the most contacted organisms. The amount of touches per diver was 5.8 touches/minute. Eﬀective carrying capacity in PNJR ranged from 15 to 35 divers/site/day. It is inferred that, in spite of the impact of scuba diving recorded on the surveyed sites, the sites showed no signs of deterioration. However, monitoring aﬀected organisms to follow up post-damage evolution and complying with the number of divers/site/day suggested in this study is recommended.

We aimed to identify biotic and abiotic factors underlying genetic structure and diversity of reef fish around Cuba. For three species, Stegastes partitus, Haemulon ﬂavolineatum and Acanthurus tractus, we investigated the effects of shared environmental factors, such as the geography of the Cuban Archipelago, and specific characteristics, such as life history traits, on genetic structure and diversity. Samples were collected at five locations around Cuba. For S. partitus and H. ﬂavolineatum, mitochondrial DNA and microsatellite loci were examined, whereas only mitochondrial DNA polymorphism was analyzed for A. tractus. All three species showed high genetic diversity. Mismatch distribution analyses suggest past population expansion in all species, but at different times in each species. Haplotype network and population genetic analyses suggest that: (1) S. partitus went through a recent population bottleneck in the late Pleistocene, (2) H. ﬂavolineatum went through a population bottleneck but earlier, in the mid-Pleistocene, and (3) A. tractus has had a large and stable population size with coalescence times that go back to the late Pliocene. Genetic polymorphism in H. ﬂavolineatum and A. tractus is homogeneous throughout the archipelago, whereas there is significant genetic structure in S. partitus. Genetic differentiation among S. partitus populations is most likely the result of the combined effects of egg type and oceanic current patterns along the Cuban coast.
“Differentiation (of Stegastes partitus) was also significant between the southern localities, i.e., the Breton and Avalos Keys. In contrast, no statistically significant differentiation between any localities was found in H. ﬂavolineatum and A. tractus, indicating genetic homogeneity.”

Marine protected areas (MPAs) have become a key component in the conservation of marine life and habitats worldwide. In Cuba, their use has also gained momentum, particularly the National Parks, the second stricter management category in the country. Surprisingly, despite well-proven efficacy of fishes as indicators of habitat status, few studies have been conducted to assess National Parks’ effectiveness in protecting the fish communities. This paper aims at analyzing the current state of knowledge and conservation status of reef fish publications about their fishes. The use of different alternatives of the visual census method undermines the comparison of reef fish assemblages among areas. Nevertheless, a common lack of big and commercially important fish species was
observed in all National Parks but Jardines de la Reina. Scarcity of scientific publications about reef fish assemblages in these National Parks triggers the need to conduct management-oriented research that contributes to the protection and sustainability of fish communities.
“Las áreas que tienen mayor
cantidad de artículos científicos sobre agregaciones de peces son el PN Jardines de la Reina,seguido del PN Guanahacabibes”
“…el estado de conservación del PN Jardines de la Reina superó las expectativas de muchos de los turistas encuestados y casi el 80% de estos lo consideraron con atractivos superiores o similares al de otros sitios del mundo…”
“El PN Jardines de la Reina fue el que tuvo los mayores valores de densidad y biomasa en ambos biotopos…”
“El área donde se observó casi la totalidad (26 especies) de las 27 especies (amenazadas seguin UICN) fue el PN Jardines de la Reina.”
“La abundancia de peces de gran talla y alto valor ecológico y comercial, y la mayor cantidad de especies amenazadas son los atributos más conspicuos en el PN Jardines de la Reina. Esto denota su efectividad en la conservación de las agregaciones de peces, lo que no se observa en los otros parques nacionales de Cuba. Esta diferencia se debe fundamentalmente al correcto manejo y la gestión dirigida a la conservación de sus ecosistemas.”
“…sobre esta zona (Jardines de la Reina) se mantiene gran atención desde muchas esferas, incluyendo la investigativa, a fin de mantener la excelencia de sus condiciones naturales.
Por tanto, en esta dirección se debe dirigir el manejo que se realice sobre las áreas marinas protegidas, y en particular sobre los parques nacionales de Cuba.”

The key results of the research about the macrophytobenthos of the Cuban marine shelf since 1973, at the Center for Marine Research at the University of Havana, are presented. Most are related with systematics of macroalgae, with 159 new records in the period. Phytobenthos ecology has been worked in the nine zones of the marine shelf. Some phytogeographical studies in Cuba and adjacent zones are reﬂected. Some of the results on the characteristics of marine angiosperms in Cuban waters and the condition of the seagrass ecosystem, composed mainly Thalassia testudinum Banks ex König, are also presented.
Seven new records of macroalgae are reported in Jardines de la Reina.

We integrated coral reef connectivity data for the Caribbean and Gulf of Mexico into a conservation decision-making framework for designing a regional scale marine protected area (MPA) network that provides insight into ecological and political contexts. We used an ocean circulation model and regional coral reef data to simulate eight spawning events from 2008–2011, applying a maximum 30-day pelagic larval duration and 20% mortality rate. Coral larval dispersal patterns were analyzed between coral reefs across jurisdictional marine zones to identify spatial relationships between larval sources and destinations within countries and territories across the region. We applied our results in Marxan, a conservation planning software tool, to identify a regional coral reef MPA network design that meets conservation goals, minimizes underlying threats, and maintains coral reef connectivity. Our results suggest that approximately 77% of coral reefs identified as having a high regional connectivity value are not included in the existing MPA network. This research is unique because we quantify and report coral larval connectivity data by marine ecoregions and Exclusive Economic Zones (EZZ) and use this information to identify gaps in the current Caribbean-wide MPA network by integrating asymmetric connectivity information in Marxan to design a regional MPA network that includes important reef network connections. The identification of important reef connectivity metrics guides the selection of priority conservation areas and supports resilience at the whole system level into the future

The composition of stony corals presents in submerged roots of Rhizophora mangle L. (red mangrove) on Jardines de la Reina National Park, was established. 300 roots were quantified, in which 11 species were identified concerning to 7 genera. Predominant species were Porites astreoides and Porites divaricata. 100 % of the colonies were found in association with crustose coralline algae, mainly from genus Neogoniolithon. Apparently, the success of the settlement of the colonies of stony corals in submerged roots of mangroves depends on the presence of crusted coralline algae.

Las comunidades de aves han sido muy estudiadas en varias localidades costeras e interiores de Cuba durante las migraciones desde principios de 1990, aunque se les ha prestado poca atención a las regiones del sur de la isla de Cuba y cayerías aledañas. En el presente trabajo se describen algunas características de la composición y estructura de las comunidades y poblaciones de aves asociadas al complejo de vegetación costera del Laberinto de las Doce Leguas (archipiélago de los Jardines de la Reina) durante las migraciones de 2009–12. Se muestrearon los cayos Grande, Anclitas y Caguama mediante redes de niebla durante al menos dos días consecutivos en las estaciones de primavera (marzo–abril) y otoño (septiembre–octubre). Se capturaron 46 especies y 745 individuos, agrupados en seis órdenes, 12 familias y 26 géneros. Se adicionaron el Tordo de Espalda Olivada Catharus ustulatus y el Solibio Icterus melanopsis a la avifauna del archipiélago de los Jardines de la Reina con la captura y observación de dos individuos en los cayos Grande y Caguama respectivamente, el 3 y 9 de octubre de 2012. Entre los dos períodos de muestreo, no se encontraron diferencias signifcativas en cuanto al número de especies capturadas por día (12,7 ± 3,65 y 12,8 ± 4,14) y a la abundancia relativa general (34,1 ± 13,5 y 35,2 ± 16,43 aves / 100 horas-red). Tampoco se encontraron diferencias signifcativas entre las estaciones de anillamiento, con los mayores valores registrados en cayo Grande para ambas variables (14,7 ± 2,81 y 41,6 ± 15,06, respectivamente). Las hembras e inmaduros fueron los individuos numéricamente dominantes durante las migraciones otoñales en las tres localidades. Durante las migraciones primaverales, la proporción entre los sexos y las clases de edad fueron más balanceadas. No se registraron tasas anuales de retorno, y la persistencia invernal se manifestó solamente para dos Mariposas Galanas Setophaga discolor en cayo Grande durante los períodos invernales 2009–10
“24 additions to the avifauna of AJR.”
“To our knowledge, the mean species number trapped per day and overall relative abundance are the first such data from Cuba’s sandy coastal scrub during migration.”
“…significantly higher percentage of juveniles and lower overall relative abundance on Caguama Cay compared to the other two ringing sites in September 2009 potentially reﬂects temporal differences in habitat quality as a result of possible detrimental effects on foraging substrate and prey availability for insectivores following Hurricane ‘Paloma’ in early November 2008. Nearly one year later, we recorded the lowest relative abundance for all field seasons when extensive structural damage to coastal vegetation (defoliation, branch breakage, uprooting) was still noted on Caguama.”
“…the geographical location of Cuba’s southern archipelagos and possibly low predation risks in the LDL may confer additional importance on the area as a stopover site for many Nearctic migrants.”

Sandy shores are known to be extreme ecosystems where the vegetation has evolved many morphological and physiological adaptations for its survival. With the aim of identify possible relationships between the vegetation´s functional diversity with abiotic factors and its corresponding quantification, we collected data on the abundance and richness of the sandy coast vegetation complex in Grande, Anclitas and Caguamas keys. Its flora is largely characterized by the dominance of hemicryptophytes and chamaephytes plants with nanophyllous leaves and displaying dispersal syndromes such as zoochory and anemochory. However, the functional groups´ richness, in the present study, varies from one key to another. Functional diversity is similar between the wet and dry seasons, and its spatial variation is influenced by the interplay of the set of abiotic factors herein studied.

Null models are an important tool aimed to predicting changes in natural communities under varying climatic conditions. Presence-absence data matrices were built up from published data on the species composition in the sandy coast vegetation of Grande, Anclitas and Caguamas keys from Cuba. For each matrix, three co-occurrence indices were calculated: number of species combinations, checkerboard score and C-score. According to the number of species combinations and C-score values, the community in Grande key during was structured by competition the rainy season. However, Caguamas and Anclitas keys showed interactions during the dry period. On the other hand, for most of the analyzed cases, the checkerboard simulation number was lower than the observed value, which indicates the compliance with the assembly rules.

The nested subset hypothesis states that species in fragmented, less species–rich biotas are non–random subsets of those inhabiting richer sites. The effect of migration on these models has not been yet fully addressed. We compared the phenological stages of the community during the spring and fall migrations. Presence–absence data of bird species occurring at 43 cays of the Jardines de la Reina archipelago was compiled and two incidence matrices were built for fall and spring periods. The degree of nestedness was estimated based on the overlap and decreasing fll, and its significance was assessed by means of 1,000 replicates of four null models. Bird assemblages showed a higher number of species during fall (67) than they did in spring (51). They also showed a significant and stable pattern of nestedness, although this was slightly higher in spring. Seasonal ﬂuctuations caused by migratory movements thus barely affected the nested structure of bird assemblages.

Biotic resistance is the idea that native species negatively aﬀect the invasion success of introduced species, but whether this can occur at large spatial scales is poorly understood. Here we re-evaluated the hypothesis that native large-bodied grouper and other predators are controlling the abundance of exotic lionfsh (Pterois volitans/miles) on Caribbean coral reefs. We assessed the relationship between the biomass of lionfish and native predators at 71 reefs in three biogeographic regions while taking into consideration several cofactors that may aﬀect fish abundance, including among others, proxies for fishing pressure and habitat structural complexity. Our results indicate that the abundance of lionfish, large-bodied grouper and other predators were not negatively related. Lionfish abundance was instead controlled by several physical site characteristics, and possibly by culling. Taken together, our results suggest that managers cannot rely on current native grouper populations to control the lionfish invasion.
Four out of eight Cuban sites were located in Jardines de la Reina

“The main EGS (environmental goods and services) of Jardines de la Reina were identified, evaluating those with higher market value and those with enough information available. In both scenarios (before and after implementing the National Park), NPV (net present value) and cost–benefit relation are above zero, so financially speaking, both are feasible. Nevertheless, the establishment of a National Park in the Jardines de la Reina area is more desirable. In both scenarios, it is evident that the non-use value of the EGS is higher than their use value.”

Marine reserves can restore fish abundance and diversity in areas impacted by overfishing, but the effectiveness of reserves in developing countries where resources for enforcement are limited, have seldom been evaluated. Here we assess whether the establishment in 1996 of the largest marine reserve in the Caribbean, Gardens of the Queen in Cuba, has had a positive effect on the abundance of commercially valuable reef fish species in relation to neighboring unprotected areas. We surveyed 25 sites, including two reef habitats (reef crest and reef slope), inside and outside the marine reserve, on five different months, and over a one-and-a-half year period. Densities of the ten most frequent, highly targeted, and relatively large fish species showed a significant variability across the archipelago for both reef habitats that depended on the month of survey. These ten species showed a tendency towards higher abundance inside the reserve in both reef habitats for most months during the study. Average fish densities pooled by protection level, however, showed that five out of these ten species were at least two-fold significantly higher inside than outside the reserve at one or both reef habitats. Supporting evidence from previously published studies in the area indicates that habitat complexity and major benthic communities were similar inside and outside the reserve, while fishing pressure appeared to be homogeneous across the archipelago before reserve establishment. Although poaching may occur within the reserve, especially at the boundaries, effective protection from fishing was the most plausible explanation for the patterns observed.

Monitoring of nesting has been used globally to estimate the population size of marine turtles. Nevertheless, monitoring effort varies widely, for instance in Cuba, four different approaches are applied: nighttime systematic monitoring, daytime systematic monitoring, sporadic monitoring with nest verification, and sporadic monitoring with no verification. These variations imply that the amount and accuracy of data gathered and the quality of derived information, differ amongst the approaches. This paper assesses the effectiveness of the different methodologies used for determining the reproduction success of marine turtles in Cuba. Nighttime systematic monitoring is only carried out in one area, while sporadic monitoring with nest verification is the most used approach along the country. The proportion of the nesting season covered with monitoring personnel is low in most of the beaches and for all the three species (Chelonia mydas, Caretta caretta and Eretmochelys imbricata), although the species in the most critical situation is hawksbill. Significant differences were found between systematic and sporadic monitoring, which has important implications for the understanding of the nesting behavior, as the capacity to detect false and true crawls essentially depends on the monitoring frequency, according to our findings. Low detection capacity in sporadic monitoring hampered the development of efficiency assessments in all the nesting beaches. In summary, despite the effort carried out nationwide to monitor nesting populations that has even increased in the last three years, important gaps exists and new monitoring strategies are needed to guarantee the right information for the species is gathered, while adequate cost-benefit balance is achieved.

The nesting colony of green sea turtles (Chelonia mydas) at Guanahacabibes Peninsula Biosphere Reserve and National Park is one of the largest in the Cuban archipelago; however, little information about its nesting ecology is available. Temporal and spatial variation in nesting and reproductive success as well as morphometric characteristics of gravid females were used to ecologically characterize this colony. Nine beaches of the Southernmost coast of Guanahacabibes Peninsula were monitored for 14 years (1998-2012) to determine green turtle nesting activity, from May to September (peak nesting season in this area). Beach dimensions were measured to determine nest density using the length and the area. Afterward the beaches were divided in two categories, index and secondary. Females were measured and tagged to compare new tagged females (823) with returning tagged females (140). Remigration interval was also determined. Temporal variation was identified as the annual number of nesting emergences and oviposits per female, with apparent peaks in reproductive activity on a biennial cycle in the first six years followed by periods of annual increase in nest number (2003-2008) and periods of decreasing number of nests (2010-2012). We also found intra-seasonal variation with the highest nesting activity in July, particularly in the second half of the month. The peak emergence time was 22:00-02:00hr. In terms of spatial variation, smaller beaches had the highest nest density and nesting was more frequent 6-9m from the high tide line, where hatchling production was maximized although hatchling success was high on average, above 80%. Morphometric analysis of females was made and newly tagged turtles were smaller on average than remigrants. Our results are only a first attempt at characterizing Guanahacabibes’ populations but have great value for establishing conservation priorities within the context of national management plans, and for efficient monitoring and protection of nesting beaches.
“C. mydas (green turtle) nesting in Cuba mostly occurs along the Southern coastlines of the Cuban archipelago, where the archipelagos of Jardines de la Reina and Los Canarreos are considered the main nesting areas for Cuban green turtles.”

Whale sharks, Rhincodon typus, aggregate by the hundreds in a summer feeding area off the northeastern Yucatan Peninsula, Mexico, where the Gulf of Mexico meets the Caribbean Sea. The aggregation remains in the nutrient-rich waters off Isla Holbox, Isla Contoy and Isla Mujeres, Quintana Roo for several months in the summer and then dissipates between August and October. Little has been known about where these sharks come from or migrate to after they disperse. From 2003–2012, we used conventional visual tags, photo-identification, and satellite tags to characterize the basic population structure and large-scale horizontal movements of whale sharks that come to this feeding area off Mexico. The aggregation comprised sharks ranging 2.5–10.0 m in total length and included juveniles, subadults, and adults of both sexes, with a male-biased sex ratio (72%). Individual sharks remained in the area for an estimated mean duration of 24–33 days with maximum residency up to about 6 months as determined by photo-identification. After leaving the feeding area the sharks showed horizontal movements in multiple directions throughout the Gulf of Mexico basin, the northwestern Caribbean Sea, and the Straits of Florida. Returns of individual sharks to the Quintana Roo feeding area in subsequent years were common, with some animals returning for six consecutive years. One female shark with an estimated total length of 7.5 m moved at least 7,213 km in 150 days, traveling through the northern Caribbean Sea and across the equator to the South Atlantic Ocean where her satellite tag popped up near the Mid-Atlantic Ridge. We hypothesize this journey to the open waters of the Mid-Atlantic was for reproductive purposes but alternative explanations are considered. The broad movements of whale sharks across multiple political boundaries corroborates genetics data supporting gene flow between geographically distinct areas and underscores the need for management and conservation strategies for this species on a global scale.

Biotic resistance, the process by which new colonists are excluded from a community by predation from and/or competition with resident species, can prevent or limit species invasions. We examined whether biotic resistance by native predators on Caribbean coral reefs has influenced the invasion success of red lionfishes (Pterois volitans and Pterois miles), piscivores from the Indo-Pacific. Specifically, we surveyed the abundance (density and biomass) of lionfish and native predatory fishes that could interact with lionfish (either through predation or competition) on 71 reefs in three biogeographic regions of the Caribbean. We recorded protection status of the reefs, and abiotic variables including depth, habitat type, and wind/wave exposure at each site. We found no relationship between the density or biomass of lionfish and that of native predators. However, lionfish densities were significantly lower on windward sites, potentially because of habitat preferences, and in marine protected areas, most likely because of ongoing removal efforts by reserve managers. Our results suggest that interactions with native predators do not influence the colonization or post-establishment population density of invasive lionfish on Caribbean reefs.
“Lionfish density in our study ranged from 0 at several sites in Belize, Cuba, and The Bahamas to ,52 individuals 100 m22 on a patch reef off Eleuthera Island, Bahamas, with an average of 4.4 individuals 100 m22 (+/20.5, SE). This range is comparable to lionfish densities found in New Providence, Bahamas and in North Carolina. Total native predator biomass was significantly higher in the 17 marine reserves we sampled and ranged widely, from 4 g 100 m22 on some spur-and-groove reefs off New Providence, Bahamas, to 51700 g 100 m22 in slope habitats of Jardines de la Reina marine reserve, Cuba. The highest predatory fish biomass value of our sites (51700 g 100 m22) is comparable to some isolated reefs of the central Pacific.”
“…in the Jardines de la Reina marine reserve in Cuba, where predator biomass was the highest observed (average ,30000 g 100 m22), lionfish were just as abundant as on the Mesoamerican Barrier Reef sites (1.5 individuals 100 m22 in Jardines de la Reina and 1.6 individuals 100 m22 on Mesoamerican Barrier Reef) that have far lower predator biomass (average ,2200 g 100 m22).”

El objetivo general de este estudio de caso es cuantiﬁcar en términos económicos, los aportes de Bienes y Servicios Ambientales del Parque Nacional Jardines de la Reina a la economía. Para cuantiﬁcar el valor económico de la actividad pesquera, se realizaron entrevistas a pescadores, capitanes de embarcación, con experiencia en la pesca de langosta dentro del Parque. En el caso de los proyectos de investigación, se utilizó la información histórica y publicaciones existentes. Se trabajó además con el plan de manejo del área para el período 2012 – 2016. Para el cálculo de la demanda turística se utilizaron datos estadísticos-ﬁnancieros compilados e información sobre estudio de mercado y prefactibilidad existente. Para caracterizar la demanda y conocer la disposición de retorno al Parque, se aplicaron cuestionarios a través de la técnica de entrevista personal. El sector de mercado encuestado fue el de extranjeros de visita en Jardines de la Reina. La muestra se seleccionó aleatoriamente. Se utilizó además la información de los estudios cientíﬁcos realizados en el área hasta el momento y se demuestra, en términos económicos, que los aportes de Bienes y Servicios Ambientales del Parque justiﬁcan los gastos por concepto de conservación de la biodiversidad del área. Si se tiene en cuenta la proyección de mejoras presentadas, tales aportes se duplicarían en los próximos diez años. Para la administración del área se necesita alrededor del 8 % del Valor Económico Total histórico de los bienes y servicios y apenas el 6% del valor de los mismos, con la proyección de la actividad turística propuesta, lo que evidencia la viabilidad económica de invertir en la administración del Parque, a través de proyectos de investigación, para garantizar la sostenibilidad del uso de los recursos naturales y por ende asegurar los ﬂujos de beneﬁcios económicos a largo plazo.

In this study, we examined physicochemical parameters and an inventory of species in the Marine Protected Area of Gran Banco de Buena Esperanza, in July 2011 and July 2012. Four sites in seagrass beds and four sites in muddy slopes were established. We measured salinity, temperature, dissolved oxygen and dissolved nutrients. The inventory was carried out using visual census. Average temperature was 30.8°C, salinity was 37.2. Dissolved oxygen ranged from 5.3 to 8.0 ml/l. The average concentration of dissolved inorganic nitrogen was 13.2 ± 9.1 µM. In seagrass beds 21 species of macroalgae, 41 species of non-sessile invertebrates and 23 species of stony corals were identified with Cladocora arbuscula and Manicina areolata dominating. We also identified colonies of Acropora cervicornis and Acropora prolifera, with no presence of Acropora palmata. Among the fish, the Lutjanidae family was predominant. In the muddy slopes 31 species of macroalgae and two angiosperms were identified. There were 45 species of non-sessile invertebrates and 42 of stony corals, with Millepora alcicornis, Porites astreoides and the genus Oculina prevailing. The average density of Diadema antillarum was 14 individual. 10m-2. The predominant fish families were Serranidae and Lutjanidae. These results provide the basis for future ecological research and have generated new hypotheses directed mainly towards the presence of possible new species and hybridization and evolution studies, focused mainly on the genus Acropora.

Seagrasses are one of the most important coastal ecosystems since they promote organic matter flow, nutrient cycling, food availability and refuge. Until now, reports on damages caused by storms and hurricanes on seagrass beds are uncommon and highly variable. The seagrass meadows of the East end of Jardines de la Reina archipelago were surveyed from Nov. 29th to Dec. 5th of 2008, in order to determinate the effects from the passing of Hurricane Paloma: a category three storm on the Saffir-Simpsom scale. A rapid field assessment of the affected areas was carried out using the manta tow technique. In six sites, seagrass was quantitatively evaluated using a 15cm diameter core (four sampling units per site) and shoot density was calculated. Remote sensing techniques were used to estimate seagrass cover. To estimate the percentage of affected areas, a Region of Interest (ROI) was first created over a Landsat image. The percentage of seagrass affected within the ROI was estimated through direct georeferentiation of the contours of the damaged area and with a comparison to the total seagrass extension. To find possible explanations for damages, a false colour image was created using the near infrared band, to highlight the differences between emerged and submerged zones. The direction of winds was estimated using ArcGis 9.2 creating circular buffers, from the centre of the hurricane and generating lines tangent to the buffers. Seagrass in the region was dominated by the angiosperm Thalassia testudinum. Regional mean density was 1 321±721 shoots/m2, a value regarded as high for the Caribbean area. Seagrass meadows were partly affected by sediment accumulation on the shoots of T. testudinum and uprooting rhizomes. The 7.6km2 disturbed area represented 1% of the total seagrass area. Other sites, closer to the centre of the hurricane, did not show any damages on the marine vegetation. The keys location with respect to the hurricane track was the most likely cause of the effects. To the North of the affected area there is an opening among the keys where the generation of waves, currents and turbulence could have occurred. Three years after the hurricane event, both vegetation cover loss and silt re-colonization by macroalgae species were observed within the affected area, by showing a patchily-vegetated landscape. This site is currently undergoing a temporal succession whose assessment demands a monitoring scheme, that will provide interesting information to document its future evolution and responsiveness against upcoming natural or anthropogenic events

Sandy coasts are extreme ecosystems, where vegetation is adapted to various stresses (salinity of the substrate, low nutrient and sporadic ﬂoods, etc.), which are mostly the result of the marine inﬂuence. During April and October 2010, we sampled the vegetation of sandy shorelines on Grande, Anclitas and Caguamas Cays, Cuba, in order to determine the spatial variations of plant diversity. On each cay, twenty plots (2 x 2 m) were randomly distributed. In these plots, we measured species richness, number of individuals, coverage, distance to the shoreline, dune height and particle size of the substrate. The vascular ﬂora was represented by twenty-one species, twenty-one genera and eleven families. Caguamas Cay was the richest. The average richness of species observed showed no significant difference between locations; however, the number of individuals was higher in Anclitas Cay. The vegetation cover was high in Anclitas and Caguamas Cays, which determined the closed structure of the vegetation. The distance to the shoreline inﬂuenced the richness of the Anclitas and Grande Cays and the number of individuals in Grande Cay. The height of the dune was related to vegetation cover, which was linked to the stability of the substrate

The ﬂoristic inventories contribute directly to knowledge of plant resources of a region. In order to inventory the vascular plant species in the Jardines de la Reina archipelago, field visits were organized and literature review. The study area was represented by 113 infrageneric taxa, 97 genera and 40 families, the keys Anclitas, Grande, Caguamas, Algodón Grande and Caballones possess the higher taxonomic richest. Endemism was low (4,5%) and alien plant species represent the 8%. The ﬂora of the archipelago was characterized by high representation of life forms shrubbery and herbaceous, with a predominance of elements neotropical and neotropical-holarctic. The sandy coastal vegetation and coastal xeromorphic scrub exhibited the highest values of specific richness.

The Caribbean Sea encompasses a vast range of physical environmental conditions that have a profound influence on the organisms that live there. Here we utilize a range of satellite and in situ products to undertake a region-wide categorization of the physical environments of the Caribbean Sea (PECS). The classification approach is hierarchical and focuses on physical constraints that drive many aspects of coastal ecology, including species distributions, ecosystem function, and disturbance. The first level represents physicochemical properties including metrics of satellite sea surface temperature, water clarity, and in situ salinity. The second level considers mechanical disturbance and includes both chronic disturbance from wind-driven wave exposure and acute disturbance from hurricanes. The maps have a spatial resolution of 1 km2. An unsupervised neural network classification produced 16 physicochemical provinces that can be categorized into six broad groups: (1) low water clarity and low salinity and average temperatures; (2) low water clarity but average salinity and temperature, broadly distributed in the basin; (3) low salinity but average water clarity and temperature; (4) upwelling; (5) high latitude; and (6) offshore waters of the inner Caribbean. Additional mechanical disturbance layers impose additional pattern that operates over different spatial scales. Because physical environments underpin so much of coastal ecosystem structure and function, we anticipate that the PECS classification, which will be freely distributed as geographic information system layers, will facilitate comparative analyses and inform the stratification of studies across environmental provinces in the Caribbean basin.
Jardines de la Reina and Golfo de Ana Maria belong to group 6 (see abstract and Table 2) characterized by a mixture of relatively warm waters with high salinity and high water clarity. However, in a more detailed resolution analysis, they are 2 separate physicochemical provinces (see Fig. 4 and Table 1).
Jardines de la Reina experienced a medium chronic stress given by wave exposure (data between 1999 to 2008) with values around 5 in a scale of 9 and a medium acute stress given by the frequency of occurrence of hurricanes Category 1–5 in the last 157 yr (1851–2008) with approximated 10 hurricanes of a maximum of 30. See Figure 6 for more information.

An analysis of marine macroalgae diversity in the Jardines de la Reina archipelago and in Nuevitas bay was done in relation to Rhodophyta, Ochrophyta and Chlorophyta. 193 infrageneric taxa: 84 Rhodophyta, 24 Ochrophyta and 85 Chlorophyta were accumulated. The species of macroalgae accumulated represents the 37% of the species known for Cuba until 2005, what demonstrates the high potential of seaweeds diversity that this archipelago and this bay have. The proportion of genera, family and orders for both areas was discussed.

We have compiled and summarized the available information regarding the avifaunal inventories conducted in 44 cays of Jardines de la Reina archipelago, by reviewing both published papers and project reports produced in the last 80 years. At present, a total of 116 bird species organized in 17 orders, 37 families and 79 genera have been reported. The best represented orders and families are Passeriformes (49), Charadriiformes (22) and Pelecaniformes (12), as well as Parulidae, Scolopacidae and Ardeidae with 21, 11 and nine species, respectively. Endemism level reaches 10% of all the species reported, being represented by one genus (Xiphidiopicus), four nationally- and four locally-distributed subspecies. Four species are classifed as Near Threatened. In regard to the permanence status, the avifauna is made up by 30 permanent residents, 18 bimodals, 25 winter residents, 10 summer residents and 32 transients. There are six abundant species, as well as 17 common, 33 uncommon, 33 rare, 26 very rare and one vagrant. Despite the current disparity in the sampling effort in different parts of the study site, larger cays such as Anclitas (87), Caguama (71) and Grande (66) stand out for harboring higher species numbers. Species with larger distributional range are Setophaga petechia, Fregata magnifcens, Ardea herodias, Thalasseus maximus and Patagioenas leucocephala.

The research was carried out in October, 2011 and March, 2012. Follow image satellite analyses 41 sites were selected in Ana Maria gulf, south region of Cuba. At these sites an inventory of the corals, gorgonians and sponges were carried out. Health status was analysed for corals. Inventories were carried out in mangrove, seagrass and coral reefs (patch reefs and sandrocky bottom biotopes) ecosystems. Species richness for corals was 41, 23 for gorgonians and 41 for sponges. More abundant corals species were Porites astreoides, Millepora alcicornis, Siderastrea siderea, Siderastrea radians, Agaricia agaricites and higher diversity was detected in patch reefs (41 species). More abundant gorgonians were Gorgonia ventalina, Erythropodium caribaeorum, Briareum asbestinum and the sponges were Mycale laevis, Cliona aprica, Iotrochota birotulata. Main affectation to coral health was bleaching (21 species experienced bleaching in some degree and only in 51% of sites). In Rabihorcado key and Algodón Grande key, were detected higher recruit abundance. Higher corals species richness was observed in: Algodón Grande key, Manuel Gómez key, Bergantines and Palomo keys. Having these results as base, this paper proposes research corals priorities relate to growth of colonies, connectivity among populations and health status of such populations in Ana Maria gulf-Jardines de la Reina ecosystem.

Nowadays there is little information about the biological diversity in the Ana Maria gulf. Most of the research in that region has been focused on fisheries and the hydrological character. Thus in 2011 a research project was initiated to fill this information gap. This paper presents a list of 105 species of marine invertebrates identified in the central part of the Ana Maria gulf. The mollusks was the best represented group of invertebrate’s animal with 43 species that represented a 40.9% of the total, followed by the echinoderms with 26 species and 24.8% of the total. The largest keys (Cuervo, Algodón Grande and Bergantines) harbored the highest species richness. These results provided a baseline for future research to deepen the study of the diversity and ecology of marine invertebrates in the sampled area and other areas of the gulf.

The objective of the present study is to provide the inventory of the terrestrial flora and vegetation in the central sector of Ana Maria gulf, southern off Ciego de Ávila province, central Cuba. By conducting field surveys, literature review as well as herbarium materials consultation, up to 47 vascular plants; grouped in 43 genera and 25 families were herein enlisted. Algodón Grande key exhibited the highest species numbers among all sampled keys, due probably to have the largest superficial area of emerged land. Three main vegetation types were identified in the study area, being the mangrove forest the most representative.

Inventory of the fish inhabiting the Jardines de la Reina archipelago, south of Cuba, were carried out between 2009 and 2012. This research presents the second check list of fish on this archipelago. The species identification was mainly in situ using random swimming. The inventory includes 283 species. This adds 37 species to the list of Jardines de la Reina ichthyofauna. The best represented families of fishes are Serranidae, Carangidae, Scaridae, Lutjanidae, Haemulidae and Pomacentridae. High abundance of large size top predators specimens of Serranidae, Lutjanidae, Sphyraenidae, Carangidae. Sharks and rays are often seen in Jardines de la Reina. It is highlighted the role of mangroves as nursery habitat of groupers due the presence of juveniles of Epinephelus itajara (Lichtenstein, 1822), Epinephelus striatus (Bloch, 1792) and Mycteroperca bonaci (Poey, 1860). High frequency of the invasive exotic species Pterois volitans (Linnaeus, 1758) is also remarkable. In Jardines de la Reina occurs 25% of the Cuban ichthyofauna, 26% of the strictly marine fish, 22% of the Chondrichthyes and 27% of the Actinopterygii. Diversity of taxa is higher in Jardines de la Reina than in the northwestern and northeastern regions of Cuba, while the most diverse families are generally the same among regions although they rank different between them.

Inventory of the fish inhabiting the Ana Maria gulf, south of Cuba, were carried out between 2010 and 2012. This research presents the first check list of fish on this region of Cuban archipelago. The species identification was mainly in situ using random swimming and surveying incidental catch of shrimp fisheries. The inventory includes 170 species. The best represented families of fishes are Serranidae, Pomacentridae, Carangidae, Haemulidae, Scaridae and Lutjanidae. It is highlighted the role of mangroves, patch reefs and complex of seagrass, coral rubble and small patch reefs as nursery habitats of snappers (Lutjanidae) and groupers (Serranidae). In Ana Maria gulf occurs 15% of the Cuban ichthyofauna, 16% of the strictly marine fish, 10% of the Chondrichthyes and 16% of the Actinopterygii. Diversity of taxa is higher in Ana Maria gulf than in the north-western region of Cuba and lower than in the north-eastern one and Jardines de la Reina, while the most diverse families are generally the same among regions although they rank different between them. Having these results as base, this paper proposes research priorities in the ecosystem Ana Maria–Jardines de la Reina gulf.

Land snails communities were surveyed in the central region of the Ana María gulf in October 2011 and March 2012. Both species density and composition were determined by using the direct count method and data were collected from 5×5 m quadrants. For each individual, the supporting plant species, vertical stratum and microhabitat used were concurrently noted. During the two sampling periods, four mollusk species were tallied (Cerion sanctacruzense, Cerion sp., Cerion sp.1 y Hemitrochus maculifera) along five keys. The two former species were distributed in two different localities, meanwhile the remainder was only found in one key. Species density reached maxima values in October 2011 by C. sanctacruzense (1,77 ind/m²) and Cerion sp. (1,70 ind/m²) in Santa María de Afuera and Palomo keys, respectively. On the contrary, H. maculifera exhibited the lowest density value (0,08 ind/m²) in the latter locality. Land snails were found in association with the 32% of the vascular plant species detected during the surveys; and the highest number of those supporting plants was reported in Santa María de Afuera and Algodón Grande keys. Most individuals of the four mollusk species were recorded in the lowest vegetation stratum (0-1 m) throughout the study site. Amongst the microhabitat more frequently used, Coccothrinax litoralis sheaths and leaves were preferred by C. sanctacruzense and Cerion sp. in Algodón Grande and Palomo keys, respectively; as well as stems by Cerion sp. in Algodoncito and Cerion sp.1 in Bergantines.

Ana Maria gulf is a zone with excellent natural characteristics and specific climatic conditions, favorable for two economic sectors very important: fishing and tourism, the second sector is more developed in the later years. There were evaluated the hidrometeorological conditions on the central portion of Ana Maria gulf, studying seventeen points in October 2011 the behavior of five meteorological elements: cloudiness, wind (direction and speed), temperature and atmospheric phenomena. All the measured and observed development were made through a methodology elaborated for this objective, applicable in zones without meteorological stations. The values of temperature, as well as the behavior of the cloudiness and the atmospheric phenomena, are representatives of the annual epoch and of a maritime clime. These results increase knowledge on the characteristics of clime and time in this geographical area.
