Epibator insularis, a new species of scincid lizard from l'Ile Walpole, New Caledonia

A new species of skink in the genus Epibator is described from Ile Walpole, a small, isolated, raised vegetated limestone platform, similar to 200 km ESE of southern New Caledonia. The new species is distinguished from its congeners Epibator nigrofas...

Contrasted ecological niches shape fungal and prokaryotic community structure in mangroves sediments

Mangroves are forest ecosystems located at the interface between land and sea where sediments presented a variety of contrasted environmental conditions (i.e. oxic/anoxic, non-sulfidic/sulfidic, organic matter content) providing an ideal ecosystem to...

Étude du caractère invasif de quelques espèces animales et végétales introduites dans les milieux dulçaquicoles en Nouvelle-Calédonie

Étude concernant quelques espèces exotiques à caractère envahissant des milieux dulçaquicoles. Elle tente de comprendre les impacts de ces espèces sur les écosystèmes et d'en contrôler la dispersion. Il s'agit des plantes Eichornia crassipes...

Surveillance du milieu marin de la grande rade de Nouméa - Suivi milieu marin SLN 2012/2013 : campagne 2012

Dans le cadre de l'arrêté ICPE du 12 novembre 2009 autorisant la Société Le Nickel à exploiter son usine de traitement de minerai de nickel de Doniambo, la SLN a missionné GINGER-SOPRONER pour réaliser la surveillance du milieu marin da...

Xestospongin B, a competitive inhibitor of IP3-mediated Ca2+ signalling in cultured rat myotubes, isolated myonuclei, and neuroblastoma (NG108-15) cel...

Xestospongin B, a macrocyclic bis-1-oxaquinolizidine alkaloid extracted from the marine sponge Xestospongia exigua, was highly purified and tested for its ability to block inositol 1,4,5-trisphosphate (IP3)-induced Ca2+ release. In a concentration-de...

Economic valuation of ecosystem services from coral reefs in the South Pacific : taking stock of recent experience

The economic valuation of coral reefs ecosystem services is currently seen as a promising approach to demonstrate the benefits of sustainable management of coral ecosystems to policymakers and to provide useful information for improved decisions. Mos...

Total phenolic, size-fractionated phenolics and fucoxanthin content of tropical Sargassaceae (Fucales, Phaeophyceae) from the South Pacific Ocean : sp...

This innovative study investigates 18 Turbinaria and Sargassum brown seaweed samples from three archipelagos of the South West Pacific Ocean. The phenolic content of crude and size-fractionated extracts was determined by the Folin-Ciocalteu method; f...

Multiple markers pyrosequencing reveals highly diverse and host-specific fungal communities on the mangrove trees Avicennia marina and Rhizophora styl...

Fungi are important actors in ecological processes and trophic webs in mangroves. Although saprophytic fungi occurring in the intertidal part of mangrove have been well studied, little is known about the diversity and structure of the fungal communit...

Spatial distribution of microbial communities in the shallow submarine alkaline hydrothermal field of the Prony bay, New Caledonia

The shallow submarine hydrothermal field of the Prony Bay (New Caledonia) discharges hydrogen- and methane-rich fluids with low salinity, temperature (< 40°C) and high pH (11) produced by the serpentinization reactions of the ultramafic baseme...

The geographical patterns of symbiont diversity in the invasive legume Mimosa pudica can be explained by the competitiveness of its symbionts and by t...

Variations in the patterns of diversity of symbionts have been described worldwide on Mimosa pudica, a pan-tropical invasive species that interacts with both alpha and beta-rhizobia. In this study, we investigated if symbiont competitiveness can expl...
