Species 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...

Cryptobenthic fish assemblages across the coral reef− seagrass continuum in SE Sulawesi, Indonesia

Cryptobenthic fishes have a significant influence on coral reef ecosystem dynamics; however, they have received considerably less attention than their larger, more conspicuous fish counterparts. In nearby seagrass zones, there is little or no information about cryptobenthic fishes, even for basic parameters such as density and distribution, although smaller organisms may have a substantial effe...

Predator-Induced Demographic Shifts in Coral Reef Fish Assemblages

In recent years, it has become apparent that human impacts have altered community structure in coastal and marine ecosystems worldwide. Of these, fishing is one of the most pervasive, and a growing body of work suggests that fishing can have strong effects on the ecology of target species, especially top predators. However, the effects of removing top predators on lower trophic groups of prey f...

Wave 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...

Changes in Biodiversity and Functioning of Reef Fish Assemblages following Coral Bleaching and Coral Loss

Coral reef ecosystems are increasingly subject to severe, large-scale disturbances caused by climate change (e.g., coral bleaching) and other more direct anthropogenic impacts. Many of these disturbances cause coral loss and corresponding changes in habitat structure, which has further important effects on abundance and diversity of coral reef fishes. Declines in the abundance and diversity of ...
