Assessment of carbon and nitrogen isotopic ratio within food webs ending to groupers in coral reefs of Wallis Island, Pacific Ocean

Characterization and sources of colored dissolved organic matter in a coral reef ecosystem subject to ultramafic erosion pressure (New Caledonia, Sout...

The eastern lagoon of New Caledonia (NC, Southwest Pacific), listed as a UNESCO World Heritage site, hosts the world's second longest double-barrier coral reef. This lagoon receives river inputs, oceanic water arrivals, and erosion pressure from ultr...

Thermal regime and host clade, rather than geography, drive Symbiodinium and bacterial assemblages in the scleractinian coral Pocillopora damicornis s...

Background: Although the term holobiont has been popularized in corals with the advent of the hologenome theory of evolution, the underlying concepts are still a matter of debate. Indeed, the relative contribution of host and environment and especial...

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...

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...

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...

Dynamics of suspended sediments during a dry season and their consequences on metal transportation in a coral reef lagoon impacted by mining activitie...
