Diurnal temporal patterns of the diversity and the abundance of reef fishes in a branching coral patch in New Caledonia.

The use of a bi-metallic structure under cathodic protection in saewater favors a 3D calcareous growth imitating the coral structure

Ephemeral and localized outbreaks of the coral predator Acanthaster cf. solaris in the southwestern lagoon of New Caledonia

Outbreaks of the coral predator Acanthaster spp., the crown-of-thorns seastar (COTS), cause major coral declines across the Indo-Pacific. However, the processes surrounding the initiation and propagation of COTS outbreaks are still unclear. We observ...

Major sources of organic matter in a complex coral reef lagoon: Identification from isotopic signatures (?13C and ?15N).

Limpus C.J.. Migrations of green turtles (Chelonia mydas) between nesting and foraging grounds across the Coral Sea.

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...

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...
