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

Small-scale spatial and temporal variability in animal abundance is an intrinsic characteristic of marine ecosystems but remains largely unknown for most animals, including coral reef fishes. In this study, we used a remote autonomous unbaited video ...

Released coral mucus does not enhance planktonic N-2 fixation rates

Dinitrogen (N-2) fixation by prokaryotic microorganisms provides bioavailable nitrogen in oligotrophic marine ecosystems such as coral reefs. The widespread though largely unknown heterotrophic diazotrophs require dissolved organic matter (DOM) for t...

Post-obduction dismantling of the early regolith and related conglomerates in the Kopeto-Boulinda-Nepoui area (New Caledonia): a possible Lower Miocen...

In New Caledonia post obduction uplift caused the erosion of the early regolith, but their timing is poorly constrained. The Nepoui Formation, on the west coast, is a witness of post-obduction deposits. This area presents stepped ferruginized surface...

Microbial island biogeography: Isolation shapes the life history characteristics but not diversity of root-symbiotic fungal communities

Island biogeography theory is one of the most influential paradigms in ecology. That island characteristics, including remoteness, can profoundly modulate biological diversity has been borne out by studies of animals and plants. By contrast, the proc...

In New Caledonia post obduction uplift caused the erosion of the early regolith, but their timing is poorly constrained. The Nepoui Formation, on the west coast, is a witness of post-obduction deposits. This area presents stepped ferruginized surface...

L'énergie thermique des mers

Ocean Thermal Energy Conversion, OTEC, is a concentrated renewable source of energy available in the one third of the world's ocean lying in the tropics. An OTEC plant is a heat engine fed with warm surface water and cold water pumped up from the dee...

Soil organic matter decomposition in semi-arid mangrove stands (New Caledonia)

Organic matter (OM) dynamics in mangrove forests have been studied extensively in terms of the capacity of their soils to store organic carbon. While δ13C, δ15N, and C/N values for mangrove soils and sources are well reported, other indicators of O...
