Comparison of different genetic distances to test isolation by distance between populations

Studying isolation by distance can provide useful demographic information. To analyze isolation by distance from molecular data, one can use some kind of genetic distance or coalescent simulations. Molecular markers can often display technical caveat...

Sedimentation of particulate matter in the south-west lagoon of New Caledonia : spatial and temporal patterns

Suspended and sedimented particulate materials were assessed monthly at five sites on the south-west lagoon of New Caledonia, from May 1986 to April 1987. Sedimentation of particulate matter was measured using sediment traps for 24 h. Resuspension, w...

Estimation of inherent optical properties using in-situ hyperspectral radiometer and MODIS data along the east coast of New Caledonia;Remote sensing o...

Hyperspectral remote sensing reflectance (Rrs) was measured by a TriOS radiometer system along the East Coast of New Caledonia during the R/V Alis 03-13 October 2011 CALIOPE cruise. The TriOS system consists of radiance and irradiance sensors measuri...

Contrat de Plan Etat Région Poitou-Charentes 1994-1998. Convention 95 RPC R 62 - Programme Pathologie - Rapport Scientifique année 1995

Le but de ce programme pathologie est de rechercher et d'étudier les agents pathogènes connus et inconnus chez les mollusques bivalves marins, plus particulièrement chez l'huître creuse, Crassostrea gigas, afin d'identifier d'éventuels agents ca...

Effect of the association of cattle and rusa deer Cervus timorensis russa on populations of cattle ticks (Boophilus microplus)

The wild population of rusa deer (Cervus timorensis russa) in New Caledonia (South Pacific) is nearly as large as the cattle population. The cattle tick is widespread and occurs all year round. Opinions are divided on the role of deer in the biologic...

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...

Rain-derived particles and CDOM distribution along the east coast of New Caledonia

Shortly after strong rains or tropical storms, chlorophyll-a concentration (Chla), turbidity, and colored dissolved organic matter (CDOM) in the lagoon of New Caledonia may be tripled. This effect is visible as far as 50 km offshore. The Eastern Coas...

Parameterizing the binding properties of dissolved organic matter with default values skews the prediction of copper solution speciation and ecotoxici...

Parameterizing speciation models by setting the percentage of dissolved organic matter (DOM) that is reactive (% r-DOM) toward metal cations at a single 65% default value is very common in predictive ecotoxicology. The authors tested this practice by...

A survey of the lizard fauna of maquis forest habitat on the Vale Inco mine site
 (20 to 30 year plan of development)

This report is from the third of studies undertaken to determine the species diversity of lizards in canopied maquis habitats, primarily maquis paraforestier and maquis preforestier, across the area encompassed by the Vale Nouvelle-Calédonie (VNC) ...

Suivi des macro-invertébrés benthiques dans la zone d’activité de Vale NC - Rapport annuel 2017

Dans le cadre de son programme de suivi environnemental et conformément à la réglementation, la société VALE Nouvelle-Calédonie doit réaliser le suivi de la qualité biologique (macrofaune benthique) des cours d'eau présents dans la zon...
