Nocturnal and lunar input patterns of pre-settlement coral reef fish in Wallis lagoon (Central South Pacific): Implications for sampling strategies

Effects of geomorphological zones, reefs and seasons on coral reef fish communities of Réunion Island, Mascarene Archipelago, SW Indian Ocean

Fisheries closure size, age, and history of compliance effects on coral reef fish communities in the western Indian Ocean

Steady water level and température in a karstic system : the case of the coral Lifou Island (SW Pacific)

Preservation of the environment on coral islands and intensification of agriculture : applied study on Maré, Loyalty Islands, New Caledonia

Les îles corail, de haute altitude, du Pacifique, forment un écosystème vulnérable caractérisé par des sols fragiles et par la présence d'eau douce qui se renouvelle lentement dans un fragile équilibre vis-à-vis de l'eau de mer. Dans les îl...

Considering multiple species attributes to better understand the effects of successive changes in protection status on a coral reef fish assemblage

Considering multiple-species attributes to understand better the effects of successive changes in protection status on a coral reef fish assemblage

The response of fish assemblages to changes in protection status is a major issue for both biodiversity conservation and fishery management. In New Caledonia, the Abore reef marine reserve harbours more than 500 fish species, and has been subjected t...

Genetic diversity, clonality and connectivity in the scleractinian coral Pocillopora damicornis: a multi-scale analysis in an insular, fragmented reef...

Clonality and genetic structure of the coral Pocillopora damicornis sensu lato were assessed using five microsatellites in 12 populations from four islands of the Society Archipelago (French Polynesia) sampled in June 2008. The 427 analysed specimens...

Wind-induced variability in larval retention in a coral reef system: a biophysical modelling study in the South-West Lagoon of New Caledonia

In the present work, a biophysical dispersal model is used to understand the role of the physical environment in determining reef fish larval dispersal patterns in the South-West Lagoon of New Caledonia. We focus on a reef fish species, the humbug da...

Accumulation of nine metals and one metalloid in the tropical scallop Comptopallium radula from coral reefs in New Caledonia

Uptake of waterborne Cd, Co, Mn and Zn was determined in laboratory experiments using radiotracer techniques (Cd-109, Co-57, Mn-54 and Zn-65). Labelled Zn was mainly accumulated in the digestive gland (65%) and Co in kidneys (81%); Cd and Mn were sim...
