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...

The population structure of benthic marine organisms is of central relevance to the conservation and management of these often threatened species, as well as to the accurate understanding of their ecological and evolutionary dynamics. A growing body of evidence suggests that marine populations can be structured over short distances despite theoretically high dispersal potential. Yet the propose...
متن کاملHT248 Physiology and behaviour of the long-spined sea urchin, a keystone Caribbean coral reef herbivore
It was only after an unidentified pathogen caused a mass mortality event, killing an estimated 98% of all individuals, that the true ecological importance of the sea urchin Diadema antillarum was understood. This mass mortality affected the entire Caribbean, all but wiping out this species on coral reefs throughout the region. Unfortunately D. antillarum are important herbivores on Caribbean re...
متن کاملCirculation of the Caribbean Sea
The geostrophic method was applied to six north-south hydrographic profiles across the Caribbean Sea and one across the Yucatan Strait. An axis of flow exists in the southern third of the Caribbean Sea. It flows directly over the steep slope in the reference layer found by Defant's method. This condition is similar to that of the Gulf Stream. The baroclinic mass distribution extends to approxim...
