Les légumineuses arborées tropicales, plantes miracles… ou presque. Expérience d'une équipe d'agro-sylvo-pastoralistes de terrain

Pour les chercheurs en biologie, les légumineuses arborées présentent de nombreuses qualités pour l'agronomie, en particulier la capacité à fixer l'azote atmosphérique. Celle-ci permet la production de parties végétales riches en matière az...

Population dynamics in some rainforests on ultramafic soils in New Caledonia and their impact on patterns of canopy richness;Deuxième conférence int...

Permanent plots are being established in monodominant and mixed rainforests over a range of altitudes on ultramafic soils in New Caledonia to investigate the factors determining canopy richness. Initial studies are examining the dynamics of the major...

Mayotte Island: another important green turtle nesting site in the southwest Indian Ocean

Situated in the north of the Mozambique Channel, Mayotte is the easternmost island of the Comoros Archipelago. From 1998 to 2005, Grande Saziley beach was monitored daily for green turtle Chelonia mydas nesting activity. Track surveys were monitored ...

Assessing the impact of removing reserve status on the Abore Reef fish assemblage in New Caledonia

We propose a statistical approach based on multivariate analysis and general linear models to test the consequences of removal of reserve status from the Abore Reef fish assemblage of the Abore Reef reserve, New Caledonia. Consequences on fish densit...

Genetic structure of the reef grouper Epinephelus merra in the West Indian Ocean appears congruent with biogeographic and oceanographic boundaries

The reef fauna connectivity of the West Indian Ocean (WIO) is one of the least studied globally. Here we use genetic analyses of the grouper Epinephelus merra (Bloch 1793) to determine patterns of connectivity and to identify barriers to dispersal in...

Osmoregulation pattern and salinity tolerance of the white shrimp Litopenaeus vannamei (Boone, 1931) during post-embryonic development

The euryhaline white shrimp Litopenaeus vannamei lives in both coastal and oceanic areas through ontogeny. Its osmoregulation pattern and variations in its tolerance to salinity are partially known from several studies under different experimental co...

Mesozoic history of the Fairway-Aotea Basin: Implications for the early stages of Gondwana fragmentation

The Fairway Ridge is a buried continental structure that separates the Fairway Basin from the New Caledonia Basin. The proposed Cretaceous age of the Fairway Basin has remained highly hypothetical to date. Deep offshore petroleum exploration wells re...

Invasion Is a Community Affair: Clandestine Followers in the Bacterial Community Associated to Green Algae, Caulerpa racemosa, Track the Invasion Sour...

Biological invasions rank amongst the most deleterious components of global change inducing alterations from genes to ecosystems. The genetic characteristics of introduced pools of individuals greatly influence the capacity of introduced species to e...
