Influence of the mode of macrofauna-mediated bioturbation on the vertical distribution of living benthic foraminifera: First insight from axial tomode...

We investigated the influence of bioturbation by macrofauna on the vertical distribution of living (stained) benthic foraminifera in marine intertidal sediments. We investigated the links between macrofaunal bioturbation and foraminiferal distributio...

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 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...

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...

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 ...

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...

Méthode de diagnostic : Estimation de la qualité des milieux dans le Grand Sud - Des données de suivis aux scores environnementaux

Dans le cadre de ses missions de suivi de l'environnement et d'information, l'Observatoire de l'environnement en Nouvelle-Calédonie (OEIL) réalise depuis 2013 une synthèse annuelle des résultats existants et disponibles des suivis environnementau...

Inventaire de 6 zones humides

Au cours de la campagne du 12 au 15 mai 2010, 6 zones humides (ZH), situées dans le Sud de la Grande Terre et dans l'emprise de l'ouverture de la « fosse minière à 5 ans » du projet minier Vale Inco, ont été inventoriées. Plusieurs techniques...
