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...

Accounting for the indirect area effect in stacked species distribution models to map species richness in a montane biodiversity hotspot

Aim Understanding how species richness is distributed is a critical prerequisite to implement efficient conservation strategies in biodiversity hotspots. Stacked species distribution models (S-SDMs) provide new opportunities to map species richness, ...

Responses of two scleractinian corals to cobalt pollution and ocean acidification

The effects of ocean acidification alone or in combination with warming on coral metabolism have been extensively investigated, whereas none of these studies consider that most coral reefs near shore are already impacted by other natural anthropogeni...

Old lineage on an old island : Pixibinthus, a new cricket genus endemic to New Caledonia shed light on gryllid diversification in a hotspot of biodive...

Few studies have focused on the early colonization of New Caledonia by insects, after the re-emergence of the main island, 37 Myr ago. Here we investigate the mode and tempo of evolution of a new endemic cricket genus, Pixibinthus, recently discovere...

Fishing for space: Fine-scale multi-sector maritime activities influence fisher location choice

The European Union and other states are moving towards Ecosystem Based Fisheries Management to balance food production and security with wider ecosystem concerns. Fishing is only one of several sectors operating within the ocean environment, competin...

Analyses of amplified fragment length polymorphisms (AFLP) indicate rapid radiation of Diospyros species (Ebenaceae) endemic to New Caledonia

Background : Radiation in some plant groups has occurred on islands and due to the characteristic rapid pace of phenotypic evolution, standard molecular markers often provide insufficient variation for phylogenetic reconstruction. To resolve relation...

Sapotaceae biogeography supports New Caledonia being an old Darwinian island

AimPanbiogeographers suggest that the biome in New Caledonia is of vicariant origin, dating from the Cretaceous - rather than being the result of repeated dispersal since c. 37Ma, when the area is postulated to have re-emerged after c. 15million year...

Complementarity of rotating video and underwater visual census for assessing species richness, frequency and density of reef fish on coral reef slopes

Estimating diversity and abundance of fish species is fundamental for understanding community structure and dynamics of coral reefs. When designing a sampling protocol, one crucial step is the choice of the most suitable sampling technique which is a...

Heterotrophic bacterial production and metabolic balance during the VAHINE mesocosm experiment in the New Caledonia lagoon

Studies investigating the fate of diazotrophs through the microbial food web are lacking, although N-2 fixation can fuel up to 50% of new production in some oligotrophic oceans. In particular, the role played by heterotrophic prokaryotes in this tran...

Emission de carbone de la Nouvelle-Calédonie

Ce document est la version française d'une lettre adressée au Président du gouvernement de la Nouvelle-Calédonie au sujet du niveau élevé d'émission de carbone par habitant de la Nouvelle-Calédonie.
