Considering multiple-species attributes to understand better the effects of successive changes in protection status on a coral reef fish assemblage

The response of fish assemblages to changes in protection status is a major issue for both biodiversity conservation and fishery management. In New Caledonia, the Abore reef marine reserve harbours more than 500 fish species, and has been subjected t...

Croissance et Société bleues : quels intérêts et perspectives pour la Nouvelle-Calédonie

This article calls back first of all a set of facts relative to the main stakes considering sea and ocean so much on the economic point of view, in the scientific technological and innovative fields, in the governance aspects as also in the culture a...

Vers une caractérisation réaliste des conditions de fonctionnement des hydroliennes

This paper presents experimental results of tests carried out in order to investigate the hydrodynamics of marine current turbines and to build an experimental database used to validate the numerical developments conducted to characterize the flow pe...

Essai d'interprétation morphologique et tectonique des levés bathymétriques exécutés dans la partie sud-est du golfe de Gascogne

The bathymetric charts based on the measurements taken near the continental shelf between the Western part of Ireland and Cap Finisterre (Spain) have been published by the Scientific and Technical Institute of Marine Fisheries.These charts were compl...

Diazotroph derived nitrogen supports diatom growth in the South West Pacific : a quantitative study using nanoSIMS

Nitrogen is essential for life but is often a major limiting nutrient for growth in the ocean. Biological dinitrogen fixation is a major source of new nitrogen to surface waters and promotes marine productivity. Yet the fate of diazotroph-derived nit...

Early taphonomy and significance of naturally submerged Nautilus shells from the New Caledonia region

The discovery of 11 Nautilus macromphalus shells in marine environments near New Caledonia constitutes the first opportunity for taphonomic analysis of empty shells of unburied, externally shelled cephalopods on the seafloor. Radiometric dating indic...

Checklist of the fishes of New Caledonia, and their distribution in the Southwest Pacific Ocean (Pisces)

A checklist of the fishes of New Caledonia is presented. A total of 2328 species in 246 families have been recorded from the region. Eight of these species are not native, but have been introduced. Five fish families are represented only by introduce...

The Coral Sea : physical environment, ecosystem status and biodiversity assets

The Coral Sea, located at the southwestern rim of the Pacific Ocean, is the only tropical marginal sea where human impacts remain relatively minor. Patterns and processes identified within the region have global relevance as a baseline for understand...

Monthly variability of self-recruitment for a coral reef damselfish

Understanding the dynamics of marine populations is critical to managing marine systems effectively and requires information on patterns of population dispersal and connectivity that are still poorly known. We used transgenerational marking to study ...

Neurymenolide A, a novel mitotic spindle poison from the New Caledonian Rhodophyta Phacelocarpus neurymenioides

The marine -pyrone macrolide neurymenolide A was previously isolated from the Fijian red macroalga, Neurymenia fraxinifolia, and characterized as an antibacterial agent against antibiotic-resistant strains that also exhibited moderate cytotoxicity in...
