Gymnocranius superciliosus and Gymnocranius satoi, two new large-eye breams (Sparoidea : Lethrinidae) from the Coral Sea and adjacent regions

Two related perciform fish species of the subfamily Monotaxinae (Sparoidea: Lethrinidae) Gymnocranius superciliosus sp. nov. and Gymnocranius satoi sp. nov. are described from specimens and tissue samples from the Coral Sea and adjacent regions. G. s...

Eocene and Oligocene basins and ridges of the Coral Sea-New Caledonia region : tectonic link between Melanesia, Fiji, and Zealandia

This paper presents 34 geochemical analyses, 24 Ar-Ar ages, and two U-Pb ages of igneous rocks from the back-arc basins and submarine ridges in the Coral Sea-New Caledonia region. The D'Entrecasteaux Ridge is a composite structural feature. Primitive...

Evolution of dissolved and particulate chromophoric materials during the VAHINE mesocosm experiment in the New Caledonian coral lagoon (south-west Pac...

In the framework of the VAHINE project, we investigated the spectral characteristics and the variability of dissolved and particulate chromophoric materials throughout a 23-day mesocosm experiment conducted in the south-west Pacific at the mouth of t...

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...

Evaluation of transgenerational isotope labeling of embryonic otoliths in a coral reef damselfish with single and repeated injections of enriched (137...

Quantifying the larval dispersal component of population connectivity is extremely challenging due to the many difficulties associated with directly observing larvae in their marine environment. Transgenerational isotope labeling is a recent empirica...

Wind-induced variability in larval retention in a coral reef system : a biophysical modelling study in the South-West Lagoon of New Caledonia

In the present work, a biophysical dispersal model is used to understand the role of the physical environment in determining reef fish larval dispersal patterns in the South-West Lagoon of New Caledonia. We focus on a reef fish species, the humbug da...

Tracking the origins of plastic debris across the Coral Sea : a case study from the Ouvéa Island, New Caledonia

Contamination of the marine environment by human-made plastic litter is a growing and global problem. Our study attempts to explain the presence of two plastic bottles beached on the Ouvéa Island, in the southwest Pacific Ocean, with trademarks from...

Preservation of the environment on coral islands and intensification of agriculture : applied study on Maré, Loyalty Islands, New Caledonia

Les îles corail, de haute altitude, du Pacifique, forment un écosystème vulnérable caractérisé par des sols fragiles et par la présence d'eau douce qui se renouvelle lentement dans un fragile équilibre vis-à-vis de l'eau de mer. Dans les îl...

Effect of marine protected areas on ecosystem resilience: interactions among juvenile coral population dynamics, benthic competition and herbivory

Effects of season, sex and body size on the feeding ecology of turtle-headed sea snakes (Emydocephalus annulatus) on IndoPacific inshore coral reefs
