Influence of live coral cover on coral-reef fish communities
The effect of percentage live coral cover on the number of fish species and individuals was determined by censusing fish from a series of reefs of comparable structural complexity, but with different proportions of live coral, in the lagoon of Mataiva Atoll, Tuamotu Archipelago. Regression analysis showed that there was a highly significant (p < 0.001) positive relationship between live coral c...
متن کاملFish-derived nutrient hotspots shape coral reef benthic communities.
Animal-derived nutrients play an important role in structuring nutrient regimes within and between ecosystems. When animals undergo repetitive, aggregating behavior through time, they can create nutrient hotspots where rates of biogeochemical activity are higher than those found in the surrounding environment. In turn, these hotspots can influence ecosystem processes and community structure. We...
متن کاملFunctionally diverse reef-fish communities ameliorate coral disease.
Coral reefs, the most diverse of marine ecosystems, currently experience unprecedented levels of degradation. Diseases are now recognized as a major cause of mortality in reef-forming corals and are complicit in phase shifts of reef ecosystems to algal-dominated states worldwide. Even so, factors contributing to disease occurrence, spread, and impact remain poorly understood. Ecosystem resilien...
متن کاملFishing degrades size structure of coral reef fish communities.
Fishing pressure on coral reef ecosystems has been frequently linked to reductions of large fishes and reef fish biomass. Associated impacts on overall community structure are, however, less clear. In size-structured aquatic ecosystems, fishing impacts are commonly quantified using size spectra, which describe the distribution of individual body sizes within a community. We examined the size sp...
