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...

Préservation des zones importantes pour la conservation des oiseaux en province Sud - Rapport final - Août 2010

Rapport faisant la présentation de la ZICO (Zone Importante pour la Conservation des Oiseaux) entre les Monts Nakada et Do afin d'aboutir à un plan d'actions pour établir des mesures de préservation du site. Onze ZICO ont été identifiées en p...

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...

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...

Heterotrophic bacterial production and metabolic balance during the VAHINE mesocosm experiment in the New Caledonia lagoon

Studies investigating the fate of diazotrophs through the microbial food web are lacking, although N-2 fixation can fuel up to 50% of new production in some oligotrophic oceans. In particular, the role played by heterotrophic prokaryotes in this tran...

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...

Development of laser ablation multi-collector inductively coupled plasma mass spectrometry for boron isotopic measurement in marine biocarbonates : ne...

Rationale: Laser Ablation coupled to Multi-Collector Inductively Coupled Plasma Mass Spectrometry (LA-MC-ICPMS) is a powerful tool for the high-precision measurement of the isotopic ratios of many elements in geological samples, with the isotope rati...

Biogeochemical fluxes and fate of diazotroph-derived nitrogen in the food web after a phosphate enrichment : modeling of the VAHINE mesocosms experime...

The VAHINE mesocosm experiment in the oligotrophic waters of the Noumea lagoon (New Caledonia), where high N-2 fixation rates and abundant diazotroph organisms were observed, aimed to assess the role of the nitrogen input through N-2 fixation in carb...
