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

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

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...

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...

Genetic diversity, clonality and connectivity in the scleractinian coral Pocillopora damicornis: a multi-scale analysis in an insular, fragmented reef...

Clonality and genetic structure of the coral Pocillopora damicornis sensu lato were assessed using five microsatellites in 12 populations from four islands of the Society Archipelago (French Polynesia) sampled in June 2008. The 427 analysed specimens...

Diurnal temporal patterns of the diversity and the abundance of reef fishes in a branching coral patch in New Caledonia

Small-scale spatial and temporal variability in animal abundance is an intrinsic characteristic of marine ecosystems but remains largely unknown for most animals, including coral reef fishes. In this study, we used a remote autonomous unbaited video ...
