Preliminary identification of key coral species from New Caledonia (Southwest Pacific Ocean), their significance to reef formation, and responses to e...

The recognition of key coral species (KCS) in the geological record, i.e. those that contribute to reef formation and maintenance of coral reef ecosystems, is important for understanding the development and evolution of reef ecosystems and for foreca...

Species specificity of bacteria associated to the brown seaweeds Lobophora (Dictyotales, Phaeophyceae) and their potential for induction of rapid cora...

While reef degradation is occurring worldwide, it is not uncommon to see phase shifts from coral to macroalgal dominated reefs. Numerous studies have addressed the mechanisms by which macroalgae may outcompete corals and a few recent studies highligh...

Development of laser ablation multi-collector inductively coupled plasma mass spectrometry for boron isotopic measurement in marine biocarbonates : ne...

Rationale: Laser Ablation coupled to Multi-Collector Inductively Coupled Plasma Mass Spectrometry (LA-MC-ICPMS) is a powerful tool for the high-precision measurement of the isotopic ratios of many elements in geological samples, with the isotope rati...

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...

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...
