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...

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 ...

Accumulation of nine metals and one metalloid in the tropical scallop Comptopallium radula from coral reefs in New Caledonia

Uptake of waterborne Cd, Co, Mn and Zn was determined in laboratory experiments using radiotracer techniques (Cd-109, Co-57, Mn-54 and Zn-65). Labelled Zn was mainly accumulated in the digestive gland (65%) and Co in kidneys (81%); Cd and Mn were sim...

Ephemeral and localized outbreaks of the coral predator Acanthaster cf. solaris in the southwestern lagoon of New Caledonia

Outbreaks of the coral predator Acanthaster spp., the crown-of-thorns seastar (COTS), cause major coral declines across the Indo-Pacific. However, the processes surrounding the initiation and propagation of COTS outbreaks are still unclear. We observ...

Major Sources of Organic Matter in a Complex Coral Reef Lagoon: Identification from Isotopic Signatures (?13C and ?15N)

The same but different: stable isotopes reveal two distinguishable, yet similar, neighbouring food chains in a coral reef

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

ACROPORA Bilan 2016

ACROPORA est le nom de coraux qui poussent en Nouvelle-Calédonie. C'est aussi le nom du projet de suivi participatif des récifs coralliens que l'OEIL a initié dans les trois communes du Grand Sud fin 2012. Depuis fin 2013, le projet est mené en p...

Évaluation des impacts du projet GORO Nickel sur les communautés biologiques marines de la baie de Kwé et de la zone portuaire de Prony.

Ce rapport constitue une évaluation des impacts du projet « Goro Nickel » sur les communautés biologiques marines de la baie Kwé et de la zone portuaire en baie de Prony.

Assessment of carbon and nitrogen isotopic ratio within food webs ending to groupers in coral reefs of Wallis Island, Pacific Ocean
