Réalisation d’enquêtes en province Sud sur les préoccupations et les attentes du grand public en matière d’environnement

L'objectif principal de cette étude est d'aider l'OEIL à orienter ses actions qui, selon les missions qui lui sont attribuées, sont définies en trois axes : la surveillance environnementale, l'optimisation de cette surveillance et enfin l'informa...

Translocation du scinque-léopard de Nouvelle-Calédonie Lacertoides pardalis sur le site proposé pour le développement de la carrière CP-A1 de Val...

Le scinque-léopard de Nouvelle-Calédonie, Lacertoides pardalis, est une espèce spécialisée, inféodée à un type d'habitat particulier, possédant un spectre alimentaire original. En raison de son aire de distribution restreinte à ces quelque...

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...

Responses of two scleractinian corals to cobalt pollution and ocean acidification

The effects of ocean acidification alone or in combination with warming on coral metabolism have been extensively investigated, whereas none of these studies consider that most coral reefs near shore are already impacted by other natural anthropogeni...

Sapotaceae biogeography supports New Caledonia being an old Darwinian island

AimPanbiogeographers suggest that the biome in New Caledonia is of vicariant origin, dating from the Cretaceous - rather than being the result of repeated dispersal since c. 37Ma, when the area is postulated to have re-emerged after c. 15million year...

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...

Aspects moléculaires et biochimiques des stylicines, peptides multifonctionnels identifiés chez la crevette bleue du Pacifique Litopenaeus stylirost...

The work reported here was motivated by the economical importance of the pacific blue shrimp Litopenaeus stylirostris farming where high mortality rates are due to bacterial and viral diseases. It consists in the characterisation of two original pept...

Effect of dietary protein level on growth and energy utilization by Litopenaeus stylirostris under laboratory conditions

A study was conducted using a bioenergetics approach to generate information on energy requirement and feed utilization of Litopenaeus stylirostris. Animals (initial mean weight 21 +/- 1 g were fed ad libitum six experimental diets, ranging from 25 t...

Introduction et invasion de l'algue tropicale Caulerpa taxifolia en Méditerranée nord-occidentale

The tropical alga Caulerpa taxifolia (Vahl) C. Agardh has been displayed over the last fifteen years in tropical aquaria at the Oceanographic Museum, Monaco. Its accidental introduction into the natural environment dates from 1984. It developed first...
