Complementarity of rotating video and underwater visual census for assessing species richness, frequency and density of reef fish on coral reef slopes...

Species Specificity of Bacteria Associated to the Brown Seaweeds Lobophora (Dictyotales, Phaeophyceae) and Their Potential for Induction of Rapid Cora...

High genetic differentiation and low connectivity in the coral Pocillopora damicornis type beta at different spatial scales in the Southwestern Indian...

Studying genetic connectivity in marine populations aims to understand the dispersal of an organism through the seascape and thus its gene flow. Here, we focused on one lineage of the recently revised coral Pocillopora damicornis complex, P. damicorn...

Correlation between catch data from bottom longlines and fish censures in the SW lagoon of New Caledonia;Proceedings of the sixth international coral ...

On a total of 363 bottoms longline sets in the SW lagoon of New Caledonia, 45 were surveyed using visual census. Abundance and biomass estimates were derived from these censuses. These estimates were highly correlated to catch per unit effort in numb...

Patterns in the trophic structure of fish populations across the SW lagoon of New Caledonia;Proceedings of the sixth international coral reef symposiu...

The cross shelf distribution of coral reef fishes according to their trophic structure is examined for 123 visual transects in the SW lagoon of New Caledonia. Abundance is maximum nearshore whereas biomass is evenly distributed across shelf. Piscivor...

Complementarity of Rotating Video and Underwater Visual Census for Assessing Species Richness, Frequency and Density of Reef Fish on Coral Reef Slopes

Estimating diversity and abundance of fish species is fundamental for understanding community structure and dynamics of coral reefs. When designing a sampling protocol, one crucial step is the choice of the most suitable sampling technique which is a...

Non-market use and non-use values for preserving ecosystem services over time: A choice experiment application to coral reef ecosystems in New Caledon...

Non-use values (i.e. economic values assigned by individuals to ecosystem goods and services unrelated to current or future uses) provide one of the most compelling incentives for the preservation of ecosystems and biodiversity. Assessing the non-use...
