| Coral reef fishes often exhibit a high degree of structure in their distribution and abundance, but the factors that influence their spatial arrangement are poorly understood. This study sought to explain the spatial structure of coral reef fish communities in the Ryukyu Archipelago. southern Japan. Visual surveys of coral reef fishes were conducted at multiple stations across the fringing reef (from the inner reef flat to the outer slope) at each of three different islands; Aka, Ishigaki and Sesoko. Spatial variation in fish communities (within and among reefs) was then compared to changes in environmental variables (water depth, distance from the shoreline, reef zone, coral abundance and coral richness). Despite being small islands, the total species... |

| Monitoring of French Polynesia coral reefs and their recent development.-French Polynesia, consisting of 118 islands in the centre of the Pacific Ocean, has more than 15 000 km(2) of reefs and lagoons managed by the local government. Tourism and pearl culture are the two main economic resources of the country. Polynesian coral reefs are extremely diverse and are among those for which we have thorough knowledge. The exploitation of local resources has been recorded for multiple decades and includes : coral materials, fishing, harvest and export of mother-of-pearl molluscs, pearl production, and ornamental fish. All over the country, many monitoring programmes have been launched to measure the health of reefs and the natural and anthropogenic perturbations... |

| The colonization of a fringing reef of Reunion Island by fish larvae takes place essentially from August to February with two peaks, in August-September, when the water temperatures are coldest, and in February when they are at a maximum. The number of fishes, as well as the number of sampled species, present similar values over two consecutive years with, nevertheless, a strong variation in the species involved. In Reunion Island, the number of post-larvae which colonise the reef is one hundred to four hundred times lower than on larger and more structured reefs. This phenomenon could be explained by the geographical characteristics of the island. The stock control of the adult fish in Reunion could largely be the result of the arrival of post-larvae on... |

| The interannual variability of the five dominant coral reef communities of the French Polynesia seascape (algae, corals, echinoderms, molluscs and fishes) was studied from 1990 to 1994 in the Tiahura sector of Moorea Island. Qualitative (species richness) and quantitative (cover percentage or density, depending on the type of community) stability is shown for benthic communities (algae, corals, echinoderms and molluscs), except for the macroalgae group and for bivalve species Tridacna maxima. In contrast, the fish community shows in its abundance a significant interannual variability characterized by a recruitment peak in 1991 and gradual and stochastic changes of densities for a few species. The bleaching events (in 1991 and 1994) and the cyclone Wasa... |
