Multifocal lenses in coral reef fishes.
The optical properties of crystalline lenses were studied in eleven species of coral reef fish from the Red Sea in Eilat, Israel. Three species each of diurnal planktivores, nocturnal planktivores and diurnal herbivores constituted three groups of animals with little within-group variability. In addition we studied two predators, which differed with respect to body size, prey preference, huntin...
متن کاملEcomorphology of Feeding in Coral Reef Fishes
Once an observer gets past the stunning coloration, surely no feature inspires wonder in coral reef fishes so much as their morphological diversity. From large-mouthed groupers, to beaked parrot fish, barbeled goatfish, long-snouted trumpet fish, snaggletoothed tusk fish, tube-mouthed planktivores, and fatlipped sweet lips, coral reef fishes display a dazzling array of feeding structures. And, ...
متن کاملThe role of cryptobenthic reef fishes in coral reef trophodynamics
An examination of the trophic status of a cryptobenthic reef fish community from the central Great Barrier Reef was carried out to evaluate the potential role of cryptobenthic fishes in coral reef ecosystems. Using frequency of occurrence data, dietary analyses revealed a diverse range of trophic groups, although detritivory (in 10 out of 16 species and 39.3% of individuals) and carnivory (5 of...
متن کاملNatural bounds on herbivorous coral reef fishes
Humans are an increasingly dominant driver of Earth's biological communities, but differentiating human impacts from natural drivers of ecosystem state is crucial. Herbivorous fish play a key role in maintaining coral dominance on coral reefs, and are widely affected by human activities, principally fishing. We assess the relative importance of human and biophysical (habitat and oceanographic) ...
متن کاملPopulation Regulation of Coral Reef Fishes
Populations of reef fish are widely believed to be limited by availability of larval recruits, not by density dependent processes operating during and after settlement of young stages in the reef environment. Our research explores and challenges this thinking. We are utilizing field observations and experiments to determine what factors affect spatial distribution, abundance, and population dyn...
