A vision for regular, rapid assessments of the tropical northwestern Atlantic's coral reefs
Rev. biol. trop; 54 (supl.3), 2006
The Atlantic and Gulf Rapid Reef Assessment (AGRRA) Program, consisting of non-fixed, transect- based visual surveys, provides "snapshot" characterizations of a number of structurally or functionally important benthic and fish indicators on tropical northwestern Atlantic (TNWA) coral reefs and Brazil. To...
The recent decline of Montastraea annularis (complex) coral populations in western Curaçao: a cause for concern?
Rev. biol. trop; 54 (supl.3), 2006
Shallow leeward reefs off the western end of Curaçao are dominated by extensive populations of M. annularis (complex). These species are larger in size (mean= 66 cm diameter) than all other species, with few small colonies (<30 cm) and notable absence of recruits. In 1998, colonies of M. annularis (c...
The white band disease type II pathogen in Puerto Rico
Rev. biol. trop; 54 (supl.3), 2006
The white band disease type I (WBD-I) epizootic event of the early 1980s resulted in significant changes in the structure and composition of coral communities throughout the wider Caribbean. The disease decimated populations of acroporid corals throughout their geographic distribution and it is still a...
Fragmentation of the gastrodermis and detachment of zooxanthellae in symbiotic cnidarians: a role for hydrogen peroxide and Ca2+ in coral bleaching and algal density control
Rev. biol. trop; 54 (supl.3), 2006
Coral bleaching involves the detachment of zooxanthellae and the simultaneous fragmentation of the gastrodermis. Results obtained with a cell permeant fluorescent probe for calcium ions (Ca2+) indicates that "thermal" bleaching is the result of a temperature related breakdown of the Ca2+ exclusion system...
A recent increase in the abundance of the echinoid Diadema antillarum in Dominica (Lesser Antilles): 2001-2005
Rev. biol. trop; 54 (supl.3), 2006
Diadema antillarum populations at many Caribbean locations have failed to recover from the pathogen-induced mortality events of the 1980s. It has become clear that the massive decline of this herbivorous urchin and the wide-spread absence of a population recovery lead to numerous long-term ecological con...
Evaluating the potential of natural reproduction and artificial techniques to increase Acropora cervicornis populations at Discovery Bay, Jamaica
Rev. biol. trop; 54 (supl.3), 2006
Shallow water Acropora species have become uncommon on north coast Jamaican coral reefs owing to a number of factors. On many reefs, algae have taken their place. The result is loss of habitat for many species of fish and invertebrates and less attractive reefs with fewer fish. These reefs appear to be p...
Status of aspergillosis and sea fan populations in Curaçao ten years after the 1995 Caribbean epizootic
Rev. biol. trop; 54 (supl.3), 2006
In 1995, a survey of sea fan corals was conducted in Curaçao during a Caribbean-wide outbreak of the sea fan disease aspergillosis. The survey was repeated in 2005 using the same methodology and identical sites to examine changes in sea fan populations 10 years after the initial epizootic. Necrotic lesi...
