Constraint-based systematic conservation planning, a generic and expressive approach : application to decision support in the conservation of New Cale...

In the context of the global biodiversity crisis, human activities are the principal cause of natural habitat degradation, fragmentation, and destruction. Globally, the species extinction rate has reached an unprecedented level in human history and a...

Nutrition, digestion et développement des larves de crevettes et poissons marins

This report is presented by Chantal Cahu for obtaining accreditation to supervise research. Since 1981, her research activity has addressed the study of reproducers' nutrition and the young stages of development of marine organisms belonging to two d...

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 ...

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 ...

Does arbuscular and ectomycorrhizal fungal inoculation improve soil aggregate stability? A case study on three tropical species growing in ultramafic ...

In many tropical regions, soil erosion from anthropogenic activities and subsequent ecological restoration are major issues. Revegetation would be an efficient way to mitigate soil degradation. Some plant and mycorrhizal species are more useful than ...

Stability of spatial structures of demersal assemblages: a multitable approach

The present work is based on a set of bottom trawl surveys performed in the Gulf of Lions between 1983 and 1992. A new method which couples the STATIS multitable approach with the logic of correspondence analysis (CoA) is proposed to study the stabil...

Biogeochemical and biological impacts of diazotroph blooms in a low-nutrient, low-chlorophyll ecosystem : synthesis from the VAHINE mesocosm experimen...

In marine ecosystems, biological N-2 fixation provides the predominant external source of nitrogen (N; 140aEuro-+/- aEuro-50aEuro-TgaEuro-NaEuro-yr(-1)), contributing more than atmospheric and riverine inputs to the N supply. Yet the fate and magnitu...

Massifs forestiers d'intérêt prioritaire - Fiches de suivi - Observations du 07 janvier 2016

Le suivi des massifs forestiers d'intérêt prioritaire est géré par Vale NC et réalisé par la société Bluecham SAS. Il sert à identifier les impacts sur la végétation à proximité de l'Usine de Vale NC par télédétection, en analysant d...

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...

Stockage géologique du CO2 en Nouvelle-Calédonie

La prise de conscience de la communauté internationale et la convergence des données scientifiques autour du réchauffement climatique rendent urgente la mise en oeuvre dans le monde entier des technologies de réduction des émissions de gaz à ef...
