Peces arrecifales someros en el islote rocoso La Viuda, Golfo Dulce, Costa Rica

Rev. biol. trop; 63 (supl.1), 2015
Resumen Los arrecifes rocosos proveen una alta diversidad de organismos. Se presentaron cambios en la estructura de la comunidad íctica a lo largo de la estación climática y la acción del oleaje. Este estudio evaluó la diversidad y la abundancia de los peces del arrecife rocoso La Viuda, Golfo Dulce...

Fatty acid composition indicating diverse habitat use in coral reef fishes in the Malaysian South China Sea

Biol. Res; 48 (), 2015
BACKGROUND: In order to understand feeding ecology and habitat use of coral reef fish, fatty acid composition was examined in five coral reef fishes, Thalassoma lunare, Lutjanus lutjanus, Abudefduf bengalensis, Scarus rivulatus and Scolopsis affinis collected in the Bidong Island of Malaysian South China...

Marine Protected Area monitoring in the nearshore waters of Grenada, Eastern Caribbean: benthic cover and fish populations

Rev. biol. trop; 62 (supl.3), 2014
Grenada is highly dependent on coral reefs as a source of food and to support tourism. Local and global environmental stressors threaten these reefs. Legislation was created for this MPA in 2001, permanent mooring buoys were deployed in 2009 and enforcement of fishing restrictions began in 2010. Initiati...

Status of the coral reefs in Foul and Folly Bays, Morant Wetlands, south-eastern Jamaica, with emphasis on corals and macroalgae

Rev. biol. trop; 62 (supl.3), 2014
Foul and Folly Bays are located within the Morant Wetlands near the eastern tip of Jamaica. They have never been investigated but were believed to be important for larval productivity because of the extent of benthic habitats, absence of major coastal developments and remote location. The study was aimed...

The results of long term coral reef monitoring at three locations in Jamaica: Monkey Island, "Gorgo City" and Southeast Cay

Rev. biol. trop; 62 (supl.3), 2014
The global and regional impacts of climate change are having devastating consequences on the coral reef ecosystems of the Caribbean. Long term monitoring are important tool for assessing reef health. Monitoring was established in 2000 in the Bahamas, Belize and Jamaica. Following the pilot project, the p...

Sulfate reducing bacteria as secondary and necessary pathogens in black band disease of corals

Rev. biol. trop; 62 (supl.3), 2014
Black band disease (BBD) is a complex, polymicrobial disease that consists of cyanobacteria, sulfide-oxidizing and sulfate-reducing bacteria (SRB), and heterotrophic bacteria. The cyanobacterium Roseofilum reptotaenium has been implicated as the primary pathogen of BBD, but other consortium members may b...

The status of coral reefs and associated fishes and invertebrates of commercial importance in Pedro Bank, Jamaica

Rev. biol. trop; 62 (supl.3), 2014
The coral reefs located off the north coast of the Jamaican mainland are some of the best and most studied reefs in the world. Coral reefs of Pedro Bank, Jamaica were assessed in March, 2012 as part of the KSLOF Global Reef Expedition using a modified Atlantic and Gulf Rapid Reef Assessment (AGRRA) proto...

Unexpected results from direct measurement, with a torsion microbalance in a closed system, of calcification rates of the coral Agaricia agaricites (Scleractinia: Agariicidae) and concomitant changes in seawater pH

Rev. biol. trop; 62 (supl.3), 2014
Ocean acidification is impacting the calcification of corals, but the mechanisms of calcification are still unclear. To explore the relationship between calcification and pH, small pieces of coral were suspended from a torsion microbalance in gently stirred, temperature controlled, seawater in a closed c...

Large-scale coral recruitment patterns on Mona Island, Puerto Rico: evidence of a transitional community trajectory after massive coral bleaching and mortality

Rev. biol. trop; 62 (supl.3), 2014
Coral reefs have largely declined across the northeastern Caribbean following the 2005 massive bleaching event. Climate change-related sea surface warming and coral disease outbreaks of a white plague-like syndrome and of yellow band disease (YBD) have caused significant coral decline affecting massive r...

Possible recovery of Acropora palmata (Scleractinia: Acroporidae) within the Veracruz Reef System, Gulf of Mexico: a survey of 24 reefs to assess the benthic communities

Rev. biol. trop; 62 (supl.3), 2014
Recent evidence shows that Acropora palmata within the Veracruz Reef System, located in the southwestern Gulf of Mexico, may be recovering after the die off from the flooding of the Jamapa River and a dramatic cold water event in the 1970s. Since this decline, few surveys have documented the status of A....
