Coral reefs are among the most species-rich and threatened ecosystems on Earth, yet the extent to which human stressors determine species occurrences, compared with biogeography or environmental conditions, remains largely unknown. With ever-increasing human-mediated disturbances on these ecosystems, an important question is not only how many species can inhabit local communities, but also which biological traits determine species that can persist (or not) above particular disturbance thresholds. Here we show that human pressure and seasonal climate variability are disproportionately and negatively associated with the occurrence of large-bodied and geographically small-ranging fishes within local coral reef communities. These species are 67% less likely to... |

This paper constitutes the first qualitative study of coral reef fish populations in the archipelago of the Glorieuses Islands (northern Mozambique Channel). Sampling by visual census techniques, at depths between 0 and 15 meters, was carried out at 30 stations spread over the whole reef. Three hundred and thirty-two (332) fish species belonging to 57 families were registered in this way. These relatively high numbers show that isolated coral reef formations, even of small size, can be endowed with a great specific richness of reef ichthyofauna. These results may be explained by an oceanic flow that favours recruitment, a diversified habitat, and low anthropogenic impact. |
