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...

Conservation priorities in a biodiversity hotspot : analysis of narrow endemic plant species in New Caledonia

New Caledonia is a global biodiversity hotspot facing extreme environmental degradation. Given the urgent need for conservation prioritisation, we have made a first-pass quantitative assessment of the distribution of Narrow Endemic Species (NES) in t...

Enjeux de développement local dans le monde pacifique

Le débat sur le développement durable invite à appréhender les problématiques économiques dans leur intégration, leur "enchâssement" dans les dynamiques sociales et culturelles plus larges. L'attention portée à la gestion des ressources nat...

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...

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 ...

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 ...

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...

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 ...

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...
