A la recherche des politiques rurales en Nouvelle-Calédonie : Trajectoires des institutions et représentations locales des enjeux de développement ...

L'étude des trajectoires des politiques rurales en Nouvelle-Calédonie vise à expliciter leur construction locale. L'analyse est réalisée en mobilisant les concepts de référentiel et de dépendance au sentier, ainsi que les notions articulées ...

Nickel-tolerant ectomycorrhizal Pisolithus albus ultramafic ecotype isolated from nickel mines in New Caledonia strongly enhance growth of the host pl...

Ectomycorrhizal (ECM) Pisolithus albus (Cooke & Massee), belonging to the ultramafic ecotype isolated in nickel-rich serpentine soils from New Caledonia (a tropical hotspot of biodiversity) and showing in vitro adaptive nickel tolerance, were ino...

Forum sur le suivi des milieux terrestres du Sud Calédonien - Surveillance des moustiques vecteurs de maladies en Nouvelle-calédonie

Forum sur le suivi des milieux terrestres du Sud Calédonien - Séance 1 : Quels sont les réseaux locaux d'observation ? Présention des 3 espèces de moustiques les plus vecteurs de maladies en Nouvelle-calédonie, des objectifs de surveillance de ...

Impact of plant root functional traits and associated mycorrhizas on the aggregate stability of a tropical Ferralsol

In many tropical regions, such as New Caledonia, soil erosion from anthropogenic activities and subsequent ecological restoration are major issues that require detailed soil and vegetation data for the production of management plans. To determine if ...

Remote sensing of Trichodesmium spp. mats in the western tropical South Pacific

Trichodesmium is the major nitrogen-fixing species in the western tropical South Pacific (WTSP) region, a hot spot of diazotrophy. Due to the paucity of in situ observations, remote-sensing methods for detecting Trichodesmium presence on a large scal...

Impact of plant root functional traits and associated mycorrhizas on the aggregate stability of a tropical Ferralsol

In many tropical regions, such as New Caledonia, soil erosion from anthropogenic activities and subsequent ecological restoration are major issues that require detailed soil and vegetation data for the production of management plans. To determine if ...

Distributions and abundances of sublineages of the N-2-fixing cyanobacterium Candidatus Atelocyanobacterium thalassa (UCYN-A) in the New Caledonian co...

Nitrogen (N-2) fixation is a major source of nitrogen that supports primary production in the vast oligotrophic areas of the world's oceans. The Western Tropical South Pacific has recently been identified as a hotspot for N-2 fixation. In the Noumea ...

Bio-optical characterization and ocean colour inversion in the Eastern Lagoon of New Caledonia, South Tropical Pacific

The Eastern Lagoon of New Caledonia (ELNC) is a semi-enclosed system surrounded by an extensive coral reef barrier. The system has been suffering impacts from climate variability and anthropogenic activities, including mining exploitation. Satellite ...

Biofilm and temperature controls on greenhouse gas (CO2 and CH4) emissions from a Rhizophora mangrove soil (New Caledonia)

Seasonal variations of CO2 and CH4 fluxes were investigated in a Rhizophora mangrove forest that develops under a semi-arid climate, in New Caledonia. Fluxes were measured using closed incubation chambers connected to a CRDS analyzer. They were perfo...

A conceptual hydrogeological model of ophiolite hard-rock aquifers in Oman based on a multiscale and a multidisciplinary approach

Ophiolites are found all over the world: from the Alps to the Himalayas, in Cuba, Papua-New Guinea, New Caledonia, Newfoundland, etc. They are composed of hard rocks—basalt, dolerite, gabbro and peridotite, which are formed at the mid-oceanic ridge...
