Herbivorous fishes and the potential of Caribbean marine reserves to preserve coral reef ecosystems

1. The development of macroalgae to the detriment of corals is now one of the major threats to coral reefs. Herbivorous fishes are partly responsible for algal regulation on coral reefs and their overexploitation favours the shift from scleractinian ...

Designing indicators for assessing the effects of marine protected areas on coral reef ecosystems: A multidisciplinary standpoint

The present paper aims at identifying and assessing indicators of the effects of Marine Protected Areas (MPAs) in coral reef regions, based on a bibliography review in ecology, economics and social sciences. First the various effects Studied within e...

Unexpected high vulnerability of functions in wilderness areas: evidence from coral reef fishes.

How accessible are coral reefs to poeple? A global assessment based on travel time.

Complex food webs in highly diversified coral reefs: insights from ?13C and ?15N stable isotopes.

Economic valuation of coral reef ecosystem service of coastal protection: A pragmatic approach

Diazotrophs : a non-negligible source of nitrogen for the tropical coral Stylophora pistillata

Corals aremixotrophs: they are able to fix inorganic carbon through the activity of their symbiotic dinoflagellates and to gain nitrogen from predation on plankton and uptake of dissolved organic and inorganic nutrients. They also live in close assoc...

Unexpected high vulnerability of functions in wilderness areas : evidence from coral reef fishes

High species richness is thought to support the delivery of multiple ecosystem functions and services under changing environments. Yet, some species might performunique functional roles while others are redundant. Thus, the benefits of high species r...

Extent of mangrove nursery habitats determines the geographic distribution of a coral reef fish in a South-Pacific archipelago.
