Taxonomie et virulence de vibrions pathogènes d'huîtres creuses Crassostrea gigas

As the emergence of new vibriosis in the European Atlantic coasts has been associated with mass mortalities of molluscs cuasing important economic losses, the project obectives are to provide knowledge and operational tools to evaluate the impact of ...

Invasion Is a Community Affair: Clandestine Followers in the Bacterial Community Associated to Green Algae, Caulerpa racemosa, Track the Invasion Sour...

Biological invasions rank amongst the most deleterious components of global change inducing alterations from genes to ecosystems. The genetic characteristics of introduced pools of individuals greatly influence the capacity of introduced species to e...

Spatial analysis of the trophic interactions between two juvenile fish species and their preys along a coastal-estuarine gradient

Coastal and estuarine systems provide nursery grounds for many marine fish species. Their productivity has been correlated with terrigeneous inputs entering the coastal-estuarine benthic food web, thereby favouring the establishment of fish juveniles...

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 ...

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...

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...

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...
