Succession within the prokaryotic communities during the VAHINE mesocosms experiment in the New Caledonia lagoon

N-2 fixation fuels similar to 50% of new primary production in the oligotrophic South Pacific Ocean. The VAHINE experiment has been designed to track the fate of diazotroph-derived nitrogen (DDN) and carbon within a coastal lagoon ecosystem in a comp...

Net ecosystem CO2 exchange in the "Coeur de Voh" mangrove, New Caledonia : effects of water stress on mangrove productivity in a semi-arid climate

In New Caledonia, a world-renowned mangrove, the "Coeur de Voh", grows in a semi-arid climate and at a high elevation in the intertidal zone. Net CO2 exchange (NEE) between the Avicennia marina shrub mangrove and the atmosphere was studied using an e...

Dissolved organic matter influences N-2 fixation in the New Caledonian lagoon (Western Tropical South Pacific)

Specialized prokaryotes performing biological dinitrogen (N-2) fixation ("diazotrophs") provide an important source of fixed nitrogen in oligotrophic marine ecosystems such as tropical and subtropical oceans. In these waters, cyanobacterial photosynt...

Impact of the use of a teaching toolbox in an awareness campaign on children's representations of coral reefs

Environmental education for children is one of the fundamental tools required to reverse the degradation of our environment and the biodiversity erosion. Currently coral reefs are part of the vulnerable ecosystems which are most threatened by human a...

Whales in warming water : assessing breeding habitat diversity and adaptability in Oceania's changing climate

In the context of a changing climate, understanding the environmental drivers of marine megafauna distribution is important for conservation success. The extent of humpback whale breeding habitats and the impact of temperature variation on their avai...

Searching for genetic markers of virulence in Vibrio nigripulchritudo, a Litopenaeus stylirostris shrimp pathogen

Since 1997, a new pathology seasonally occurs in new caledonian shrimp farms during the warm season. Diseased Litopenaeus stylirostris shrimp suffer from a systemic vibriosis which was attributed to highly pathogenic Vibrio nigripulchritudo. At the p...
