Tuna fishing accounts for over 70% of GDP in small island countries in the Western and Central Tropical Pacific. However, this activity is threatened by global warming, which could displace or reduce tuna populations.
29 juin 2025
With climate change comes acidification and warming of the oceans, and if this increases, the consequences for coral reefs could be dramatic.

Based on technology that has been in use for over twenty years, the study of DNA fragments left behind by organisms in the environment is undergoing unprecedented development thanks to a revolution on two fronts - microelectronic and digital.
29 juin 2025
Urbanisation, resource over exploitation, pollution, habitat destruction and climate change are responsible for the sixth mass extinction of species - a global phenomenon that scientists are trying to quantify as much as possible.
26 juin 2025
Tropical cyclones are among the most devastating natural disasters, and the flooding they cause is responsible for over 90% of the human and material losses observed during these events.

La sensibilisation des populations littorales est une étape clé pour favoriser la conservation et la protection des écosystèmes aquatiques, en particulier les récifs coralliens.
18 juin 2025
Technologie utilisée depuis plus de vingt ans, l'étude des fragments d'ADN laissés par les organismes dans l'environnement connaît un développement sans précédent grâce à une double révolution microélectronique et numérique.
18 juin 2025
Pour que les mesures de gestion des espaces et des espèces marines soient appropriées et appliquées, il importe de considérer les principaux acteurs concernés et les réalités locales. Les collectivités de la Nouvelle-Calédonie expérimentent différentes ap…

Le changement climatique s'accompagne d'une acidification et d'un réchauffement de l'océan dont l'amplification pourrait avoir des conséquences dramatiques sur les récifs coralliens.
17 juin 2025
La pêche au thon représente plus de 70 % du PIB des petits pays insulaires du Pacifique tropical Ouest et central. Or, cette activité est menacée par le réchauffement climatique qui risque de déplacer ou de réduire les populations de thons.
17 juin 2025
Les cyclones tropicaux sont parmi les risques naturels les plus dévastateurs, et les inondations qu'ils provoquent sont responsables de plus de 90 % des pertes humaines et matérielles observées lors de ces événements.
10 juin 2025
Large marine predators feeding on fish caught on fishing gear, a behaviour termed "depredation", frequently results in conflicts with significant ecological and socio-economic impacts. While adjusting fishing practices through spatio-temporal avoidance of…

Nutrient subsidies from seabirds (SDN) significantly impact coral reef ecosystems, but access to remote seabird nesting islands limits our understanding of how corals respond to this nutrient source. This study investigates the in natura effects of SDN on…
10 juin 2025
Small Pelagic Fish (SPF) exhibit large fluctuations in abundance and distribution in response to environmental variability. To maintain the resilience of fishing communities and develop effective and equitable climate adaptation strategies, improved under…

The mesophotic zone between 60 and 150 m of water depth is of increasing interest to science and management considering its biological communities, the species physiology, and the biological and physical connections with the shallower domain at a variety …
13 mai 2025
Coral recruitment is an essential demographic mechanism that underpins the community structure and dynamics of coral reefs and facilitates post-disturbance coral recovery. However, information on coral recruitment patterns in mesophotic coral ecosystems (…
