Surveillance du milieu marin de la grande rade de Nouméa - Suivi milieu marin SLN 2012/2013 : campagne 2012

Dans le cadre de l'arrêté ICPE du 12 novembre 2009 autorisant la Société Le Nickel à exploiter son usine de traitement de minerai de nickel de Doniambo, la SLN a missionné GINGER-SOPRONER pour réaliser la surveillance du milieu marin da...

Comparaison des méthodes et données d’analyses acquises dans le cadre du suivi du milieu marin de Vale Nouvelle-Calédonie - campagne d'août 2012

L'OEIL a pour mission de recueillir les données environnementales produites par les industriels, de les gérer et de les interpréter. Dans un souci d'intégrité et d'objectivité l'OEIL doit également effectuer des vérifications de la qualité s...

From the western boundary currents to the Pacific Equatorial Undercurrent: Modeled pathways and water mass evolutions

The hydrological and geochemical properties of the waters constituting the Pacific Equatorial Undercurrent (EUC) determine the properties of the equatorial cold tongue. Understanding and quantifying the various EUC origins is therefore of prime impor...

Effects of Oceanic Salinity on Body Condition in Sea Snakes

Since the transition from terrestrial to marine environments poses strong osmoregulatory and energetic challenges, temporal and spatial fluctuations in oceanic salinity might influence salt and water balance (and hence, body condition) in marine tetr...

Vulnerability to xylem embolism as a major correlate of the environmental distribution of rain forest species on a tropical island

Increases in drought-induced tree mortality are being observed in tropical rain forests worldwide and are also likely to affect the geographical distribution of tropical vegetation. However, the mechanisms underlying the drought vulnerability and env...

Processes driving the adaptive radiation of a tropical tree (Diospyros, Ebenaceae) in New Caledonia, a biodiversity hotspot

Due to its special geological history, the New Caledonian Archipelago is a mosaic of soil types, and in combination with climatic conditions this results in a heterogeneous environment across relatively small distances. A group of over 20 endemic spe...

Metagenomic and PCR-based diversity surveys of [FeFe]-hydrogenases combined with isolation of alkaliphilic hydrogen-producing bacteria from the serpen...

High amounts of hydrogen are emitted in the serpentinite-hosted hydrothermal field of the Prony Bay (PHF, New Caledonia), where high-pH (similar to 11), low-temperature (< 40 degrees C), and low-salinity fluids are discharged in both intertidal and s...

Trait coordination, mechanical behaviour and growth form plasticity of Amborella trichopoda under variation in canopy openness

Understanding the distribution of traits across the angiosperm phylogeny helps map the nested hierarchy of features that characterize key nodes. Finding that Amborella is sister to the rest of the angiosperms has raised the question of whether it sha...

Multiple markers pyrosequencing reveals highly diverse and host-specific fungal communities on the mangrove trees Avicennia marina and Rhizophora styl...

Fungi are important actors in ecological processes and trophic webs in mangroves. Although saprophytic fungi occurring in the intertidal part of mangrove have been well studied, little is known about the diversity and structure of the fungal communit...

Spatial distribution of microbial communities in the shallow submarine alkaline hydrothermal field of the Prony bay, New Caledonia

The shallow submarine hydrothermal field of the Prony Bay (New Caledonia) discharges hydrogen- and methane-rich fluids with low salinity, temperature (< 40°C) and high pH (11) produced by the serpentinization reactions of the ultramafic baseme...
