The swift decline of coral reefs stands out as a significant biodiversity challenge confronting our generation, and mesophotic coral ecosystems (MCEs; reefs between 30 and 150 m) have been proposed as refuge habitats that may be less affected by climate c…

The semienclosed Bourake lagoon in New Caledonia is a natural system that enables observation of evolution in action with respect to stress tolerance in marine organisms, a topic directly relevant to understanding the consequences of global climate change…

The marine microbiome arouses an increasing interest, aimed at better understanding coral reef biodiversity, coral resilience, and identifying bioindicators of ecosystem health. The present study is a microbiome mining of three environmentally contrasted …
11 mars 2025
Predatory and large-bodied coral reef fishes have fundamental roles in the functioning and biodiversity of coral reef ecosystems, but their populations are declining, largely due to overexploitation in fisheries. These fishes include sharks, groupers, Hum…
11 mars 2025
Prey abundance and quality are dynamic in time and space, impacting predator ecology. We examine variation in species-specific krill quantity and quality as prey for humpback whales in the Northern California Current region, using generalized additive mod…
11 mars 2025
The susceptibility of species to habitat changes depends on which ecological drivers shape individual fitness components. To date, only a few studies have quantified fitness components such as the Lifetime Reproductive Success across multiple generations …
11 mars 2025
Geographical barriers and sea-level fluctuations have significantly influenced the population genetic structure and evolutionary history of Indo-West Pacific (IWP) reef species. This study examines these effects in Abudefduf septemfasciatus (banded sergea…
11 mars 2025
Coastal ecosystems in Pacific Island Countries and Territories are vital to local livelihoods, yet increasingly face pressures from urbanization. In Fiji, the Greater Suva Urban Area, where one-third of the nation's population live, exemplifies these chal…

Les données de capture à la palangre de surface lors des campagnes de capture et d'élimination des requins responsables d'attaques sur des humains dans le lagon de la Nouvelle-Calédonie (2016-2023)
ont été utilisées pour caractériser la diversité des gra…
Recensement de la colonie de puffins du Pacifique (Ardenna pacifica) de Pindaï en Nouvelle-Calédonie
25 févr. 2025
L'objectif du présent travail est l'estimation de la taille de la colonie de puffins du Pacifique Ardenna pacifica de la péninsule de Pindaï sur la côte ouest de la Grande Terre de la Nouvelle-Calédonie (mer de Corail), à partir de douze
