- Abstract
Se estudiaron siete lagunas artificiales de agua dulce (L1 –L7) en el municipo de Ciego de Ávila (Cuba), los cuales se caracterizaron según criterios genéticos, hidrológicos y morfológicos. Todas son lagunas, de origen antrópico, relativamente recientes. Una de ellas es semipermanente (L.1) y las restantes son permanentes. A partir de la identificación de las plantas presentes en parcelas delineadas,desde los bordes de las lagunas,fue confeccionada una lista florística. Los taxones identificados fueron catalogados según su origen y presencia en Cuba, hábito de crecimiento, utilidad para el hombre, comportamiento ante el impacto antrópico y estado de conservación. Se registraron 49 especies pertenecientes a 44 géneros y 34 familias. En L.3 y L.6 (lagunas ubicadas en las Canteras del aereopuerto) se identificó el mayor número de especies (27 y 26 respectivamente) y en L.1, el menor (7). Predominaron plantas exóticas y sinantrópicas y abundaron las invasoras, lo cual indica el tránsito por etapas tempranas de la sucesión ecológica. No obstante, se detectó un 31 % de plantas autóctonas y un 2 % de endemismo. Un 4 %se encuentran amenazadas de extinción, clasificadas en Peligro Crítico. El 39 % tiene uso medicinal, el 29 % ornamental, el 12 % son fitorremediadoras y el 4 % aparecen frecuentemente incorporadas a prácticas folclóricas. Las plantas asociadas a estas lagunas artificiales del municipio de Ciego de Ávila presentan condiciones, valores y usos diversos, lo que incrementa los servicios ambientales de estos ecosistemas., Seven artificial freshwater lagoons (L1-L7) were studied in Ciego de Ávila, Cuba. They were characterized using different genetic, hydrologic, and morphologic criteria. All the environments were young and lagoons of anthropogenic origin; one is a temporary pond (L.1), and the others are permanent. A floristic list was made to identify the plants present in delineated parcels at the borders of the lagoons. The identified taxa were classified according to their origin and presence in Cuba, growth form, usefulness for humans, response to anthropic impacts, and conservation status. Forty-nine (49) species from 44 genera and 34 families were recorded. Most species (27 and 26, respectively) were identified at L.3 and L.6 (lagoons formed in old stone quarries used to construct the local airport). The least(seven) at L.1. Exotic and synanthropic plants prevailed, and invasive species were abundant, which indicates the transition through the early stages of ecological succession. 31 % of autochthonous plants and 2 % of endemic plants were recorded. 4 % is critically endangered. 39 % of these plants are medicinal, 29 % ornamental,12 % are phytoremediators, and 4 % are frequently used in folklore-related practices. Plants that live in the freshwater environments of Ciego de Avila municipality have diverse characteristics, values, and uses that increase the environmental services ofthese ecosystems.

This study was conducted in the Jardines de la Reina National Park, Cuba. The health of the communities of corals and crustose coralline algae was studied in the years 2001, 2012 and 2017. The probable effect of hurricanes and sea surface temperature on these communities was also assessed. The area was only affected by three hurricanes and a tropical storm from 2000 to 2017. Sea surface temperature showed an increasing trend (by 0.03°C). The highest percentage of old mortality was recorded in 2001 (74% on the fore reef and 53% on reef crests) and the lowest of recent mortality in 2012 (0.03% on the fore reef and 0.17% on reef crests). Coral cover increased on the fore reef by between 3% and 2% in 2017 in comparison with 2001 and 2012. On the reef crests, the highest cover percentage was in 2001 (14.8%). Unlike local stressors, it was determined that hurricanes and sea surface temperature have likely negatively affected the coral reefs, particularly on reef crests. Both habitats have shown resistance and/or recovery capacity from the impacts suffered after 2001, which suggests some level of resilience., Este estudio se realizó en el Parque Nacional Jardines de la Reina, Cuba. Se estudió la salud de las comunidades de corales y algas coralinas costrosas en los años 2001, 2012 y 2017. También se evaluó el probable efecto de los huracanes y la temperatura superficial del mar sobre dichas comunidades. La zona solo ha sido afectada por tres huracanes y una tormenta tropical en este siglo (desde 2000 hasta 2017). La temperatura de la superficie del mar mostró una tendencia creciente (en 0.03°C). El mayor porcentaje de Mortalidad Antigua se registró en 2001 (74% en arrecife frontal y 53% en crestas del arrecife) y el más bajo de Mortalidad Reciente en 2012 (0.03% en arrecife frontal y 0.17% en crestas del arrecife). La cobertura de coral aumentó en el arrecife frontal en 2017, entre 3% y 2%, respecto de 2001 y 2012. En las crestas del arrecife, el mayor porcentaje de cobertura se registró en 2001 (14.8%). A diferencia de los factores de estrés locales, se determinó que los huracanes y la temperatura de la superficie del mar probablemente hayan afectado negativamente a los arrecifes de coral, particularmente a las crestas del arrecife. Ambos hábitats han mostrado resistencia y/o capacidad de recuperación de los impactos sufridos después de 2001, lo que sugiere cierto nivel de resiliencia.

- Abstract
In order to know the health status of the reefs, some protocols have been created toevaluate various ecological indicators on focal groups of organisms that inhabit these reefs. In this study we a specific scale, for classification and status score, for six ecological indicators (coral density, number of species per transect, coverage, old death, recent death and recruits population density) of the coral community of the Jardines de la Reina National Park. Were studied 29 SCUBA diving sites, located in fore reefs and designated as reference sites, which were compared with 52 other sites not used for diving. Also, were studied 27 reef crests, using the most conserved crests in the study area, as the reference site (La Puntica), although in this case, another indicator (density of recruits) was added. The non-parametric Kruskal Wallis test was applied and frequency analysis was carried out through the Statistica 7 program. For evaluated ecologic indicators were proposed some changes in the specific scale, with regard to the suggested for Cuba and the Great Caribbean, adapting the levels of a new scale to obtained values from integral analysis, taking into account, the reference sites. With a condition of “Very Good”, density was classified with values >20 colonies 10 m-1in fore reefs and >14 colonies 10 m-1in crests. The number of species with values >10 in fore reefs and ≥ 6 in crests. The coral covers>30 % for both habitats. Old mortality ≤10 % for both habitats. Recent mortality, ≤1 % for both habitats. Recruitspopulation density, with values >20 recruits m-2in fore reefs and >10 recruits m-2in crests. We recommend one specificscale for classification and score was for health status for each MPAs, which would allow made some management actions, according to each coral reef intrinsic behaviors., Para conocer el estado de salud de los arrecifes se han creado protocolos que permiten evaluar indicadores ecológicos sobre grupos focales de organismos que habitan en ellos. En este estudio se propone una escala específica, de clasificación y puntaje de condición de salud, para seis indicadores ecológicos (densidad, número de especies por transecto, cobertura, muerte antigua, muerte reciente y densidad de reclutas) de la comunidad de corales del Parque Nacional Jardines de la Reina. Se estudiaron 29 sitios de buceo autónomo SCUBA, situados en escarpes poco profundos y designados como sitios de referencia, que fueron comparados con otros 52 sitios no utilizados para el buceo. También se estudiaron 27 crestas de arrecifes, usando como sitio de referencia la más conservada del área de estudio (La Puntica). Se aplicó la prueba no paramétrica de Kruskal Wallis y se realizó un análisis de frecuencia a través del programa Statistica7. Para los indicadores ecológicos evaluados se propusieron cambios en la escala específica, con respecto a la sugerida para Cuba y el Gran Caribe, adecuando los niveles de la nueva escala a los valores obtenidos en un análisis integral y teniendo en cuenta, fundamentalmente, los sitios de referencia. Con una condición de “Muy buena”, se clasificó la densidad con valores >20 colonias 10 m-1en escarpes y >14 colonias 10 m-1en crestas. El número de especies, >10 en escarpes y ≥6 en crestas. La cobertura >30% para ambos hábitats. Muerte antigua ≤10% para ambos hábitats. Mortalidad reciente, ≤1% para ambos hábitats. Densidad poblacional de reclutas, >20 reclutas m-2en escarpes y >10 reclutas m-2en crestas. Se recomienda la creación de una escala específica de clasificación y puntaje para la condición de salud en cada AMPs, lo que permitiría realizar acciones de manejo acorde a las características intrínsecas de sus arrecifes coralinos

- Abstract
In the Caribbean, coral reefs have been changing constantly as a result of local and global impacts. These changes are also expected to occur in the Jardines de la Reina National Park. The work described here has been carried out to analyze the temporal variation of populations of the dominant groups S. siderea, Orbicella spp., A. agaricites and P. astreoides during 2001, 2012 and 2017, which have been found to have changed in other reefs of Cuba and the Caribbean. During 2001 and 2012 14 sites were surveyed in 88 transects every year, and during 2017 at 24 sites in 240 transects. In 2001, the AGRRA methodology was used; in 2012 and 2017, a new version of this methodology was applied. Six thousand five hundred and one (6,501) colonies were counted and 35 species were identified. S. siderea had an abundance (P = 0.6861) and density (P = 0.0712) which did not vary significantly between the different surveys. The abundance and density of Orbicella spp. decreased between 2001 (24% - 3.2 colonies 10 m-1), 2012 (14% - 1.4 colonies 10 m-1), and 2017 (13% - 1.9 colonies 10 m-1). The abundance of A. agaricites also did not vary significantly between the different surveys (P = 0.2202), while its density increased (2001-2012: 1.4 colonies 10 m-1, 2017: 2 colonies 10 m-1). The abundance of P. astreoides increased (2001: 8%, 2012: 10%, 2017: 12%) as did its density (2001- 2012: 1 colony 10 m-1, 2017: 1.7 colonies 10 m-1). The coral S. siderea prevailed in the reefs, and Orbicella spp. underwent a reduction that caused temporal variation with a displacement toward A. agaricites and P. astreoides., No Caribe, os recifes de corais vêm mudando constantemente como resultado de impactos locais e globais. Tais modificações também devem ocorrer no Parque Nacional Jardines de la Reina. Por isso, este trabalho foi proposto para analisar a variação temporal das populações de S., siderea, Orbicella spp., A. agaricites e P. astreoides, como grupo dominante, entre 2001, 2012 e 2017. Estas espécies têm mostrado mudanças em outros recifes em Cuba e no Caribe. Em 2001 e 2012, foram estudados 14 locais, sendo 88 transeções por ano e em 2017, 24 locais e 240 transeções. Em 2001, foi utilizada a metodologia AGRRA; e, uma versão desta em 2012 e 2017. Foram contabilizadas 6.501 colônias e identificadas 35 espécies. S. siderea apresentou abundância (P = 0,6861) e densidade (P = 0.0712) sem diferenças significativas. Orbicella Spp. diminuíram em abundância e densidade entre 2001 (24% - 3.2 colônias 10 m-1), 2012 (14% - 1.4 colônias 10 m-1) e 2017 (13% - 1,9 colônias 10 m-1). A. agaricites manteve sua abundância sem diferenças significativas (P = 0.2202) e aumentou sua densidade (2001-2012: 1,4 colônias 10 m-1, 2017:2 colônias 10 m-1). P. astreoides aumentou sua abundância (2001: 8%, 2012:10%, 2017: 12%) e densidade (2001 e 2012): 1 colônia 10 m-1, 2017: 1,7 colônias 10 m-1). S. siderea dominou nos recifes e Orbicella spp. teve uma diminuição que gerou variação temporal com deslocamento para A. agaricites e A. astreoides., En el Caribe, los arrecifes coralinos han estado en constante cambio, como consecuencia de los impactos locales y globales. Se espera que tales modificaciones también ocurran en el Parque Nacional Jardines de la Reina. Por ello, este trabajo se propuso analizar la variación temporal de las poblaciones de S. siderea, Orbicella spp., A. agaricites y P. astreoides, como grupo dominante, entre el 2001, 2012 y 2017. Estas especies han mostrado cambios en otros arrecifes de Cuba y del Caribe. En el 2001 y 2012, se estudiaron 14 sitios, con 88 transectos cada año y en el 2017, 24 sitios y 240 transectos. En el 2001, se utilizó metodología AGRRA; en el 2012 y 2017 fue empleada una versión de esta. Se contaron 6 501 colonias y se identificaron 35 especies. S. siderea tuvo una abundancia (P = 0.6861) y densidad (P = 0.0712) sin diferencias significativas. Orbicella spp. disminuyó en abundancia y densidad entre 2001 (24% - 3.2 colonias 10 m-1), 2012 (14% - 1.4 colonias 10 m-1) y 2017 (13% - 1.9 colonias 10 m-1). A. agaricites mantuvo su abundancia sin diferencias significativas (P = 0.2202) y aumentó su densidad (2001-2012: 1.4 colonias 10 m-1, 2017: 2 colonias 10 m-1). P. astreoides incrementó su abundancia (2001: 8%, 2012: 10%, 2017: 12%) y densidad (2001 y 2012: 1 colonia 10 m-1, 2017: 1.7 colonias 10 m-1). S. siderea dominó en los arrecifes y Orbicella spp. tuvo una disminución que generó variación temporal con desplazamiento hacia A. agaricites y P. astreoides.

Stable isotopes of nitrogen (δ15N) have been widely used around the world to evaluate the impactof anthropogenic activities on marine ecosystems; however, in the Caribbean Sea countries, such asMéxico and Cuba, they are rarely used. Inputs of nutrients related to urban development and touristactivities along the coasts of the Caribbean Sea have the potential to deteriorate their fragile marineecosystems. The use of isotopic tools and elemental analysis in sentinel organisms would be usefulto provide evidence of the impact generated by anthropogenic nutrients. Measurements ofδ15N (h),carbon and nitrogen content, and C:N ratios, were conducted in different sentinel groups (macroalgae,seagrasses, gorgonians, and corals) collected in five marine ecosystems with different nearby coastaldevelopment pressure in both countries. The selected ecosystems, ordered according to the level ofcoastal areas development (low to high), were: Jardines de la Reina (JR), Gulf of Ana Maria (GAM),Cayo Coco (CC), and Laguna Larga (LL) in Cuba, and Puerto Morelos (PM) in México. Results evidencedthat the majority of sentinels inhabiting near the most developed coastal areas, in terms of populationand tourism, showed higher N contents, lower C:N ratios and higher values ofδ15N (e.g., PM andLL) than those near less developed coastal ecosystems (e.g., GAM and JR). Land-based nutrients frommunicipal wastewater constitute the primary source of N pollution. Because eutrophication representsasignificantthreattotheintegrityofvaluablecoastalecosystems,thereisanurgentneedtoaccelerateprogress in wastewater treatment systems, in terms of capacity and efficiency, to significantly reducenutrient inputs to coastal ecosystems. Otherwise, more negative changes and deteriorations to thehealth of coastal ecosystems, including coral reefs, are expected along the Mexican Caribbean andnumerous key points of Cuba and other Caribbean countries

- Abstract
Seagrass meadows are considered one of the most valuable ecosystems of the biosphere. In the Northern Keys of the Ciego de Ávila province, seagrass showed structural and composition damages due to hurricane Irma’s impact. The state of seagrass meadows was evaluated at Las Coloradas and El Paso beaches in November 2017 after the hurricane, based on a characterization conducted in June 2017. For both samples, three 50 m transects were located parallel to the coast. Along each transect, 12 0.25 m2 frames were placed. The predominant marine angiosperm was T. testudinum, and S. filiforme at a lower scale. A total of 25 macroalgae species and four stony coral species were identified. The most predominant invertebrate species found were O. reticulatus and L. gigas, while the most abundant fish species were H. bivittatus and G. cinereus. In November, S. filiforme disappeared, the diversity of invertebrates associated with seagrasses declined, and no ichthyofauna was recorded. Hurricane Irma was an extreme meteorological event that changed the composition and structure of seagrass meadows at Las Coloradas and El Paso beaches, because of its impact in the decrease of the relative abundance and shoot density of T. testudinum, the height of dossal, and the epiphytism percentage of the species, as well as the decrease in seagrass fauna. Seagrass sites must continue to be monitored to study their level of recovery over time. Los pastos marinos están considerados entre los ecosistemas más productivos de la biosfera. En la cayería norte de la provincia de Ciego de Ávila presentaron daños en su estructura y composición debido a la incidencia del huracán Irma. Luego del paso de este fenómeno, se evaluó el estado de los pastos marinos en playas Las Coloradas y El Paso, en noviembre de 2017, sobre la base de una caracterización realizada en junio de 2017. Para ambos muestreos, se ubicaron tres transectos de 50 m paralelos a la costa; en cada uno de ellos se situaron 12 marcos de 0.25 m2. La angiosperma marina predominante fue T. testudinum, en menor proporción S. filiforme. Se identificaron 25 especies de macroalgas y 4 de corales pétreos. Entre los invertebrados predominaron las especies O. reticulatus y L. gigas. Los peces de mayor abundancia fueron H. bivittatus y G. cinereus. En noviembre desapareció S. filiforme, disminuyó la diversidad de invertebrados y no se registró ictiofauna. El huracán Irma fue un evento meteorológico extremo que cambió la composición y estructura de las praderas de pastos marinos en los sitios de playa Las Coloradas y El Paso, al incidir en la disminución de la abundancia relativa y la densidad de vástagos de T. testudinum y afectar la altura del dosel y el porcentaje de epifitismo de esta especie, así como en la reducción de la fauna asociada. Se debe continuar el monitoreo de los sitios de pastos marinos, con el fin de estudiar su nivel de recuperación en el tiempo. As ervas marinhas são consideradas um dos ecossistemas mais produtivos da biosfera. O arquipélago norte da província de Ciego de Ávila apresentou danos em sua estrutura e composição devido à incidência do furacão Irma. Após a passagem desse fenômeno, o estado das ervas marinhas nas praias Las Coloradas e El Paso foi avaliado em novembro de 2017, com base em uma caracterização realizada em junho de 2017.

- Abstract
Seagrass meadows are considered one of the most valuable ecosystems of the biosphere. In the Northern Keys of the Ciego de Ávila province, seagrass showed structural and composition damages due to hurricane Irma’s impact. The state of seagrass meadows was evaluated at Las Coloradas and El Paso beaches in November 2017 after the hurricane, based on a characterization conducted in June 2017. For both samples, three 50 m transects were located parallel to the coast. Along each transect, 12 0.25 m2 frames were placed. The predominant marine angiosperm was T. testudinum, and S. filiforme at a lower scale. A total of 25 macroalgae species and four stony coral species were identified. The most predominant invertebrate species found were O. reticulatus and L. gigas, while the most abundant fish species were H. bivittatus and G. cinereus. In November, S. filiforme disappeared, the diversity of invertebrates associated with seagrasses declined, and no ichthyofauna was recorded. Hurricane Irma was an extreme meteorological event that changed the composition and structure of seagrass meadows at Las Coloradas and El Paso beaches, because of its impact in the decrease of the relative abundance and shoot density of T. testudinum, the height of dossal, and the epiphytism percentage of the species, as well as the decrease in seagrass fauna. Seagrass sites must continue to be monitored to study their level of recovery over time., As ervas marinhas são consideradas um dos ecossistemas mais produtivos da biosfera. O arquipélago norte da província de Ciego de Ávila apresentou danos em sua estrutura e composição devido à incidência do furacão Irma. Após a passagem desse fenômeno, o estado das ervas marinhas nas praias Las Coloradas e El Paso foi avaliado em novembro de 2017, com base em uma caracterização realizada em junho de 2017. Para ambas as amostras, foram localizadas três transeções de 50m paralelas à costa; em cada uma delas foram colocados 12 quadros de 0,25 m2. A angiosperma marinha predominante foi T. testudinum, em menor proporção S. filiforme. Foram identificadas 25 espécies de macroalgas e 4 de corais pedregosos. Entre os invertebrados, predominaram as espécies O. reticulatus e L. gigas. Os peixes mais abundantes foram H. bivittatus e G. cinereus. Em novembro, o S. filiforme desapareceu, a diversidade de invertebrados diminuiu e nenhuma ictiofauna foi registrada. O furacão Irma foi um evento climático extremo que alterou a composição e a estrutura dos leitos de ervas marinhas nos locais das praias de Las Coloradas e El Paso ao incidir na diminuição da abundância relativa e da densidade de hastes de T. testudinum e ao afetar a altura do dossel e a porcentagem de epífitas desta espécie, bem como na redução da fauna associada. O monitoramento dos locais de ervas marinhas deve continuar, a fim de estudar seu nível de recuperação ao longo do tempo., Los pastos marinos están considerados entre los ecosistemas más productivos de la biosfera. En la cayería norte de la provincia de Ciego de Ávila presentaron daños en su estructura y composición debido a la incidencia del huracán Irma. Luego del paso de este fenómeno, se evaluó el estado de los pastos marinos en playas Las Coloradas y El Paso, en noviembre de 2017, sobre la base de una caracterización realizada en junio de 2017. Para ambos muestreos, se ubicaron tres transectos de 50 m paralelos a la costa; en cada uno de ellos se situaron 12 marcos de 0.25 m2. La angiosperma marina predominante fue T. testudinum, en menor proporción S. filiforme. Se identificaron 25 especies de macroalgas y 4 de corales pétreos. Entre los invertebrados predominaron las especies O. reticulatus y L. gigas. Los peces de mayor abundancia fueron H. bivittatus y G. cinereus. En noviembre desapareció S. filiforme, disminuyó la diversidad de invertebrados y no se registró ictiofauna. El huracán Irma fue un evento meteorológico extremo que cambió la composición y estructura de las praderas de pastos marinos en los sitios de playa Las Coloradas y El Paso, al incidir en la disminución de la abundancia relativa y la densidad de vástagos de T. testudinum y afectar la altura del dosel y el porcentaje de epifitismo de esta especie, así como en la reducción de la fauna asociada. Se debe continuar el monitoreo de los sitios de pastos marinos, con el fin de estudiar su nivel de recuperación en el tiempo.

- Abstract
Coral recruitment is a key ecological process for the maintenance and recovery of natural populations in coral reefs. To determine the number of coral recruits, in the Jardines de la Reina National Park, a frame (0.25 m x 0.25 m) was used. The frame was placed every 2 m, in 10 m long transects, until 50 squares were completed in each study site. A total of 12 sites on reef crests and 24 sites on slopes were studied. On the reef crests, the sites were distributed among three reserve zones and on the slopes, the sites were distributed among five reserve zones. On the crests, the average density of recruits did not show significant differences for the areas of the reserve (p<0.292). Six species were identified, predominantly Porites astreoides at the Reserva Oeste zone (4.8 colonies/m²) and Agaricia spp. in the Reserva Extremo Oeste (3.8 colonies/m²). On the slopes, significant differences were observed, mainly, between the Reserva Extremo Este and the Reserva Extremo Oeste (p<0.009). Nineteen species were identified, predominantly Agaricia spp. (13.1 colonies/m²) and Siderastrea siderea (14.1 colonies/m²) in the Reserva Oeste. The highest density of coral recruits is found towards the West of the park, and in particular, it was on slopes where the highest densities prevailed. [ABSTRACT FROM AUTHOR]

- Abstract
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 resuspension, 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., Una de las actividades que más se desarrolla en el Parque Nacional Jardines de la Reina (PNJR), ubicado al sur de las provincias de Sancti Spíritus, Ciego de Ávila y Camagüey, es el buceo autónomo. Sobre esta base se realizó un estudio acerca de la incidencia de dicha actividad sobre los arrecifes de esta región, específicamente, sobre los corales pétreos. Para ello se estudiaron 28 sitios, en 10 días, lo que permitió comparar zonas de alta, media, baja y sin intensidad de buceo en cuanto al porcentaje de cobertura viva de los corales, mediante 220 transectos lineales y con la observación de 51 buceadores. En los sitios con alta intensidad de buceo se identificaron 36 especies de corales, siendo las más abundantes: S. siderea, A. agaricites, P. astreoides, M. alcicornis y O. faveolata. De los 51 buceadores observados, 48 cometieron infracciones: contactos sobre los organismos, resuspensión de sedimentos, y en menor medida, daños mecánicos (rompimiento). Las gorgonias fueron los organismos más contactados, seguidas por los corales. La cantidad de toques por buceador en el PNJR fue de 5.8 toques/min. La capacidad de carga efectiva en el PNJR varió entre 15 y 35 buceadores/sitio/día. Se infiere que los sitios de buceo del PNJR, a pesar de la incidencia del buceo autónomo sobre ellos, no muestran deterioro. No obstante, se recomienda monitorear los organismos afectados para conocer con precisión su evolución ante las incidencias, así como cumplir con el número de buceadores/sitio/día que se sugiere en este estudio.

- Abstract
The Jardines de la Reina National Park is regarded as the largest marine reserve in the Caribbean. To determine the efffect of the protection gradient that stretches from the central reserve to the east and west ends of the park, on the status of the communities of corals and coralline costrose algae, 12 sites in the reef crests and 24 sites in the slopes were surveyed during September and October, 2017. Crests were sorted out into three reserve zones and the slopes into five. To determine the status of corals, the ecological indicators number of species, percent cover, recent mortlity and old mortality were used. In the case of algae, only percent cover was measured. Regarding the number of coral species, no significant differences were observed among the reserve zones. In the reef crests, Millepora complanata, Porites astreoides and Acropora palmata prevailed among the 20 species recorded. Coral cover and recent mortality showed no significant differences among the reserve zones, unlike old mortality (p<0.015) and algal cover (p<0.015). In the reef slopes, 32 species were identified with prevalence of Siderastrea siderea and Agaricia agaricites. Coral cover (p<0.000) and algal cover (p<0.000), showed significant differences among the reserve zones, but not recent mortality and old moratlity. The effect of the protection gradient on the status of corals and crustose coralline algae of the park was not evident. [ABSTRACT FROM AUTHOR]

- Abstract
Caballones Canal is a tidal channel that separates the Anclitas and Caballones keys from the outer edge of the Jardines de la Reina National Park, Cuba. In this study, we characterize the status of four seagrass bed sites of Pasa Caballones in 2015 and 2016. To estimate the density of seagrasses a quadrat of 0.25 x 0.25 cm was placed on three 50 m transects parallel to the coast. At each site, we measured physico-chemical parameters such as temperature, salinity, visibility, nutrients. We used bottom trawls to determine fish species composition. The predominant angiosperm in the surveys was Thalassia testudinum. We found differences in both, the average density of short shoots between sites for years (457 and 473 shoots/m2 for 2015 and 2016 respectively), as well as the average height of the canopy (26 and 29 cm for 2015 and 2016, respectively). For both years calcareous greens macroalgae of the genera Halimeda and Penicillus were dominant. We identified 24 fish species from 46 individuals; Sparisoma chrysopterum (14 individuals) and Monacanthus spp (17 individuals) were the most representative in surveys. Nutrient concentration was higher than other seagrass zones in Cuba and Caribbean Region. Sea grasses beds in these sites showed no signs of propellers scars, despite being one of the areas with the largest amount of tourist boats in the region. This study constitutes an ecological basis for future monitoring of sea grasses in other tidal channels representative of the PNJR. [ABSTRACT FROM AUTHOR]

- Abstract
The Guanahacabibes Peninsula was proposed as a Managed Resource Protected Area (APRM) in the Cuban National System of Protected Areas. In order to validate this proposal a study was conducted as part of the project “Implementation of a Regional Approach to the Management of Marine and Coastal Protected Areas in Southern Cuban Archipelagos”, with the purpose of characterizing coastal ecosystems and reassuring that the APRM designed location and extension correspond to the protection of the main natural resources of the region. Mangroves, coastal lagoons and seagrass were assessed as well as important sites for seabird and waterfowl communities and manatee populations. Sampling was conducted with methods validated in the project. Results included the baseline of the area and identified 149 algae species, 4 seagrass species, 53 mangrove fish species, and 39 seabird and waterfowl species. The sites selected as priority for habitat and species conservation and management include feeding and nesting sites for seabirds and waterfowl and two important sites for the manatee. The main problems for the area were identified for future conservation and management actions., La Península de Guanahacabibes fue propuesta como Área Protegida de Recursos Manejados (APRM) en el Sistema Nacional de Áreas Protegidas de Cuba. Para validar esta propuesta se realizó un estudio de caracterización al área, en el marco del proyecto “Aplicación de un enfoque regional al manejo de las áreas protegidas marinas y costeras en los archipiélagos del sur de Cuba”, con el objetivo de caracterizar los ecosistemas costeros y reafirmar que la ubicación y extensión diseñada del APRM responden a la protección de los principales valores naturales. Se evaluaron los manglares, las lagunas costeras y los pastos marinos, así como los sitios más importantes para las comunidades de aves marinas y acuáticas y las poblaciones de manatíes. Los muestreos se realizaron con metodologías validadas en el marco del proyecto. Se presentan los resultados que constituyen la línea base del área, identificándose 149 especies de algas, 4 especies de fanerógamas marinas, 53 especies de peces del manglar y 39 especies de aves marinas y acuáticas. Los sitios seleccionados como prioridades de conservación y manejo de hábitats y especies incluyen los sitios de alimentación y nidificación de las aves marinas y acuáticas y la ubicación de dos zonas importantes para el monitoreo del manatí. Se identificaron las principales problemáticas del área, con el objetivo de realizar futuras acciones de conservación y manejo de los recursos naturales.

- Abstract
Octocoral and stony coral communities in the Jardines de la Reina archipelago (Cuba) were studied in 2001 and again in 2005. The incidence of the 2005 bleaching event in the Caribbean was analyzed in the stony coral community. Twelve sampling stations were established: seven in the shallow forereef and five in reef crests, with one square meter quadrants to estimate density. A total of 62 species (26 octocorals and 36 stony corals) were identified in the shallow forereef, including Pseudopterogorgia americana (2.4 colonies/m2), Eunicea flexuosa (1.1 colonies/m2), Siderastrea siderea (5.0 colonies/m2) and Agaricia agaricites (4.0 colonies/m2). In the reef crest, 31 species were identified (13 octocorals and 18 stony corals), with Briareum asbestinum (1.3 colonies/m2), Porites astreoides (2.5 colonies/m2) and Millepora complanata (1.0 colonies/m2) being the most abundant. The most sensitive species to bleaching were: A. agaricites, Millepora spp. and Montastraea annulariS. In general, this event showed a poor incidence with stony corals. Constant monitoring is necessary to adjust the management plan to the changes that may occur in the structure of the benthic communities., En los años 2001 y 2005, se estudió la composición de las comunidades de octocorales y corales pétreos en el archipiélago de los Jardines de la Reina. Se analizó, en la comunidad de corales pétreos, la incidencia del blanqueamiento ocurrido en el 2005 en el Caribe. Para ello se establecieron doce estaciones de muestreo (siete en el arrecife frontal somero y cinco en el arrecife de cresta), en cada una de estas se estimó la densidad mediante el marco cuadrado de 1 m de lado. En el arrecife frontal somero se identificaron un total de 62 especies (26 de octocorales y 36 de corales), siendo las más abundantes: Pseudopterogorgia americana (2.4 colonias/m2), Eunicea flexuosa (1.1 colonias/m2), Siderastrea siderea (5.0 colonias/m2) y Agaricia agaricites (4.0 colonias/m2). En el arrecife de cresta se identificaron un total de 31 especies (13 de octocorales y 18 de corales), predominando: Briareum asbestinum (1.3 colonias/m2), Porites astreoides (2.5 colonias/m2) y Millepora complanata (1.0 colonias/m2). Las especies más sensibles al blanqueamiento fueron: A. agaricites , Millepora spp. y Montastraea annularis. En sentido general, dicho suceso tuvo una incidencia pobre sobre los corales pétreos. Es menester la ejecución de monitoreos al permitir ajustar los planes de manejo en función de los cambios que puedan ocurrir en la estructura de las comunidades bentónicas.

Four of coral reef crestswere sampledin the Jardines de la Reina National Park, Cuba, to know their conditionin 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.

- Abstract
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 Neogoniolithon gender. 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. [ABSTRACT FROM AUTHOR]

- Abstract
The composition, structure and condition of stony coral and fish communities in the Desembarco del Granma National Park (PNDG) and the Managuano Fauna Refuge (RFMG) in the province of Granma, Cuba were analyzed. Sampling took place in July 2012. For stony corals, 53 line transects were set and 570 coral colonies were counted. Fishes were listed using the drift diving census method for 50 min., while for species density and biomass the five-meter radius stationary method was applied. In the PNDG 25 species of corals of 14 genera, 11 families and 2 orders were recorded; also 97 fish species from 55 genera, 34 families and 8 orders. In the RFMG, 18 coral species from 10 genera, 9 families and 2 orders as well as 56 fish species from 34 genera, 23 families and 6 orders, were recorded. Average old mortality in corals was 18 % and live coral cover ranged from 6,8 % to 19,2 %. No disease was detected. The composition and structure of stony corals in the PNDG and the RFMG were not significantly different from those described for other Cuban coral reefs; health of such communities was regarded as good. Richness offish species was not high, probably due to the effect of fisheries in the said areas. [ABSTRACT FROM AUTHOR]

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.

- Abstract
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 sidereal (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.

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 sand-rocky 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.

- Abstract
In the spur-and-groove reefs of the Ecological Reserve Siboney-Juticí (Southeast Cuba) octocorals are one of the predominant components of the sessile fauna. Main objectives of the present paper are characterizing the composition, structure and conservation status of the octocoral communities and assessing on the prevailing environmental conditions in the study area. For data collection, six sampling sites were located every 2-3 km ranging from 12 m to 17 m depth along the spur-and-groove reefs. In each site, 22-26 lm2 quadrants were zigzag arranged every 2 m. The density of colonies was determined per site. The severity degree and predictability of environmental conditions were inferred by using the Heterogeneity and Equitability indexes, respectively. Hydrodynamic stress and the Comparative Pollution Index were also assessed. Current affectations of the octocoral communities were also determined and classified into four main categories: mechanical damage, diseases, predation and invertebrate and macroalgae overgrowth. As a result, 25 species represented by 752 colonies were recorded and Eunicea flexuosa and Gorgonia ventalina were the most abundant. The occurrence of Eunicea succinea forma succinea constituted the first report for Eastern Cuba. Site densities ranged from 3.58 +/- 1.84 to 7.58 +/- 2.16 colonies/m2 and considered from moderate to low. The biggest densities were reported at both sides of the San Juan River mouth. Despite of the composition and structure of the octocoral communities, low to high hydrodynamic stress and low and moderate levels of contamination were inferred, it is likely that these indexes could have been overestimated due to the sensitivity of the indicator species to other factors such as sedimentation. The environmental conditions were mostly favorable and stable. In general, the number of dead colonies was low and mostly caused by the detachment of the substrate and overgrowth of Millepora alcicornis. Injuries were mainly brought about by mechanical damage, followed by coenenchyme loss, predation by Cyphoma gibbosum and macroalgae overgrowth. On the other hand, negative effects by Hermodice carunculata predation, bleaching, Red Band and Black Band Disease were not observed. Among sampled species, G. ventalina colonies were the most severely damaged within the community. As a whole, octocoral communities of spur-and-groove reefs in the Ecological Reserve Siboney-Juticí showed a good conservation status.
