Vibrio aestuarianus zinc metalloprotease causes lethality in the Pacific oyster Crassostrea gigas and impairs the host cellular immune defenses

Extracellular products (ECPs) of the pathogenic Vibrio aestuarianus 01/32 were previously reported to display lethality in Crassostrea gigas oysters and to cause morphological changes and immunosuppression in oyster hemocytes. To identify the source ...

A leguminous species exploiting alpha- and beta-rhizobia for adaptation to ultramafic and volcano-sedimentary soils : an endemic Acacia spirorbis mode...

Acacia spirorbis subsp. spirorbis Labill. is a widespread tree legume endemic to New Caledonia that grows in ultramafic (UF) and volcano-sedimentary (VS) soils. The aim of this study was to assess the symbiotic promiscuity of A. spirorbis with nodula...

L'air en Bref

Ce panneau d'information fait office d'introduction à la sensibilisation sur la surveillance de la qualité de l'air en Nouvelle-Calédonie. Il présente l'atmosphère, les différentes couches qui la constituent et son utilité ainsi que sa compos...

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...

High rate algal pond treatment for water reuse in a marine fish recirculation system: Water purification and fish health

Regardless of the degree of closure of a recirculation system, effluents are produced and replacement water is needed, which limits the possibility of locating a seawater production system away from the shoreline. At the Palavas Ifremer station, in t...

Interspecific comparison of Cd bloaccumulation in European Pectinidae (Chlamys varia and Pecten maximus)

The uptake and loss kinetics of Cd were determined in two species of scallops from the European coasts, the variegated scallop Chlamys varia and the king scallop Pecten maximus, following exposures via seawater, phytoplankton and sediment using highl...

Seuils indicateurs pour la surveillance des paramètres physico-chimiques dans les eaux douces superficielles du Grand Sud - Phase 1 : Evaluation des ...

Dans le cadre de ses missions, l'OEIL centralise les données de suivi acquises entre autres au niveau des cours d'eaux de l'hydro-éco-région du plateau ultramafique du Grand Sud (HER D - environ une quinzaine de cours d'eau) et notamment du périm...
