Résultats du suivi IBS en période d'étiage - Centre minier de Dothio - Novembre 2018

Le document présente les résultats du suivi de l'Indice Bio-Sédimentaire (IBS) en période d'étiage (basses eaux) du centre minier de Dothio. Ce suivi est effectué afin de contrôler l'influence des activités minières de la SLN sur la qualitÃ...

Résultats du suivi IBS en période d'étiage - Année 2017 - Site minier du Massif Dothio

Le document présente les résultats du suivi de l'Indice Bio-Sédimentaire (IBS) en période d'étiage (basses eaux) sur le site minier du Massif Dothio. Ce suivi est effectué afin de contrôler l'influence des activités minières de la SLN sur l...

Biodiversity of Mimosa pudica rhizobial symbionts (Cupriavidus taiwanensis, Rhizobium mesoamericanum) in New Caledonia and their adaptation to heavy m...

Rhizobia are soil bacteria able to develop a nitrogen-fixing symbiosis with legumes. They are taxonomically spread among the alpha and beta subclasses of the Proteobacteria. Mimosa pudica, a tropical invasive weed, has been found to have an affinity ...

A framework for mapping small-scale coastal fisheries using fishers' knowledge

Collecting spatial information on fisheries catch and effort is essential to understanding the spatial processes of exploited population dynamics and to manage heterogeneously distributed resources and uses. The use of fishers' knowledge through geog...

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...

Génotypage des géniteurs de Lates calcarifer de Tahiti : aide à la domestication raisonnée du Loup Tropical pour la filière tahitienne

The tropical seabass Lates calcarifer was introduced in Tahiti in 1984 and then was domesticated without other introduction. Three successive generations have been obtained in captivity. Tissue samples of the 38 animaIs which represent the total Tahi...

Variability in diel and seasonal in situ metabolism of the tropical gastropod Tectus niloticus

Researchers often use metabolic measurements in the field over narrow time periods to estimate an organism's metabolism over large time scales. Here, we measured in situ respiration, calcification and excretion rates of the tropical gastropod Tectus ...

Application of the support vector regression method for turbidity assessment with MODIS on a shallow coral reef lagoon (Voh-Kone-Pouembout, New Caledo...

Particle transport by erosion from ultramafic lands in pristine tropical lagoons is a crucial problem, especially for the benthic and pelagic biodiversity associated with coral reefs. Satellite imagery is useful for assessing particle transport from ...

Transcriptome data from three endemic Myrtaceae species from New Caledonia displaying contrasting responses to myrtle rust (Austropuccinia psidii)

The myrtle rust disease, caused by the fungus Austropuccinia psidii, infects a wide range of host species within the Myrtaceae family worldwide. Since its first report in 2013 in New Caledonia, it was found on various types of native environments whe...

Inferring savannah-rainforest boundary dynamics from vegetation structure and composition : a case study in New Caledonia

A direct consequence of deforestation and forest fragmentation in the tropics is the increased importance of boundaries between forest fragments and savannahs. These boundaries are critical zones for understanding the dynamics of savannahs and forest...
