Rhizosphere bacteria of Costularia spp. from ultramafic soils in New Caledonia: diversity, tolerance to extreme edaphic conditions, and role in plant ...

Des rhizobactéries ont été isolées des racines de Costularia spp., carex pionnières des sols ultramafiques de Nouvelle-Calédonie, un " hotspot " de la biodiversité dans le Pacifique Sud. L'identification du genre, les capacités à tolérer le...

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...

Is it possible to raise, offspring of the 25th generation of Litopenaeus vannamei (Boone) and 18th generation Litopenaeus stylirostris (Stimpson) in c...

Peneid shrimp are commonly reared in clear-water aquaria or tanks for short-term studies of 4-6 weeks during controlled experiments, such as nutrition studies to estimate dietary nutrient requirements. Recently, in line with the genetic program at Ce...

Phytoplankton community structure in the VAHINE mesocosm experiment

The VAHINE mesocosm experiment was designed to trigger a diazotroph bloom and to follow the subsequent transfer of diazotroph-derived nitrogen (DDN) in the rest of the food web. Three mesocosms (50m(3)) located inside the Noumea lagoon (New Caledonia...

Comparative genomics of pathogenic lineages of Vibrio nigripulchritudo identifies virulence-associated traits

Vibrio nigripulchritudo is an emerging pathogen of farmed shrimp in New Caledonia and other regions in the Indo-Pacific. The molecular determinants of V. nigripulchritudo pathogenicity are unknown; however, molecular epidemiological studies have sugg...

The major outer membrane protein OmpU of Vibrio splendidus contributes to host antimicrobial peptide resistance and is required for virulence in the o...

Vibrio splendidus, strain LGP32, is an oyster pathogen associated with the summer mortalities affecting the production of Crassostrea gigas oysters worldwide. Vibrio splendidus LGP32 was shown to resist to up to 10 mu M Cg-Def defensin and Cg-BPI bac...

Characterization of molecular processes involved in the pearl formation in Pinctada margaritifera for a sustainable development of pearl farming indus...

Tahiti’s pearl farming industry plays a major socio-economic role in French Polynesia. In an increasingly competitive market where the production of high quality pearls becomes essential, research can help secure and ensure sustainable production. ...

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...

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...

Chemogeography of the red macroalgae Asparagopsis : metabolomics, bioactivity, and relation to invasiveness

Introduction The Latitudinal Gradient Hypothesis (LGH) foresees that specialized metabolites are overexpressed under low latitudes, where organisms are subjected to higher herbivory pressure. The widespread macroalga Asparagopsis taxiformis is compos...
