Diazotrophs : a non-negligible source of nitrogen for the tropical coral Stylophora pistillata

Corals aremixotrophs: they are able to fix inorganic carbon through the activity of their symbiotic dinoflagellates and to gain nitrogen from predation on plankton and uptake of dissolved organic and inorganic nutrients. They also live in close assoc...

Extent of mangrove nursery habitats determines the geographic distribution of a coral reef fish in a South-Pacific archipelago.

Complex food webs in highly diversified coral reefs: insights from ?13C and ?15N stable isotopes.

Impact of the use of a teaching toolbox in an awareness campaign on children's representations of coral reefs

Environmental education for children is one of the fundamental tools required to reverse the degradation of our environment and the biodiversity erosion. Currently coral reefs are part of the vulnerable ecosystems which are most threatened by human a...

An optimised passive acoustic sampling scheme to discriminate among coral reefs' ecological states

In the present era of rapid global change, innovative monitoring methods can greatly enhance our ability to detect ecological disturbances and prioritise conservation areas in a timely and cost-effective manner. While Passive Acoustic Monitoring (PAM...

Quantifying the shelter capacity of coral reefs using photogrammetric 3D modeling: From colonies to reefscapes

Structural complexity plays a key role in the functioning of coral reef ecosystems. Reef-building corals are major contributors to this complexity, providing shelter and food for numerous invertebrates and fish species. Both structural complexity and...

Spatial distribution of small pelagic fish in the lagoon of New Caledonia;Proceedings of the 6th international coral reef symposium

Two acoustic surveys have been done in the lagoon all around New Caledonia, with a digital integrator. The cruises lasting two weeks were done at six month interval. Much information has been obtained on stock biomass and spatial distribution of fish...

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...
