Coral Reef Health Indices versus the Biological, Ecological and Functional Diversity of Fish and Coral Assemblages in the Caribbean Sea
This study evaluated the relationship between the indices known as the Reef Health Index (RHI) and two-dimensional Coral Health Index (2D-CHI) and different representative metrics of biological, ecological and functional diversity of fish and corals in 101 reef sites located across seven zones in the western Caribbean Sea. Species richness and average taxonomic distinctness were used to asses b...
متن کاملWave energy and swimming performance shape coral reef fish assemblages.
Physical factors often have an overriding influence on the distribution patterns of organisms, and can ultimately shape the long-term structure of communities. Although distribution patterns in sessile marine organisms have frequently been attributed to functional characteristics interacting with wave-induced water motion, similar evidence for mobile organisms is lacking. Links between fin morp...
متن کاملQuaternary coral reef refugia preserved fish diversity.
The most prominent pattern in global marine biogeography is the biodiversity peak in the Indo-Australian Archipelago. Yet the processes that underpin this pattern are still actively debated. By reconstructing global marine paleoenvironments over the past 3 million years on the basis of sediment cores, we assessed the extent to which Quaternary climate fluctuations can explain global variation i...
متن کاملAbundance,diversity, andactivityofmicrobial assemblages associatedwith coral reef¢shguts and feces
Feces and distal gut contents were collected from three coral reef fish species. Bacteria cell abundances, as determined via epifluorescence microscopy, ranged two orders of magnitude among the fishes. Mass-specific and apparent cell-specific hydrolytic enzyme activities in feces from Chlorurus sordidus were very high, suggesting that endogenous fish enzymes were egested into feces. Denaturing ...
متن کاملSpecies and space: role of volume in organizing coral reef fish assemblages in SE Cuba
A reliable species–area relationship holds true for a number of terrestrial systems. When species–area data are plotted on logarithmic axes, the slope bears strong consistency across taxa. This study examined effects of habitat space on the diversity of coral reef fish species. Because habitat space on coral reefs is 3-dimensional, we developed and employed a methodology that accounts for volum...
