The New Caledonian archipelago is an important hotspot of marine biodiversity. Due to mining activities, urbanization, and industrialization, significant amounts of contaminants are discharged into the lagoon. This study analysed the concentrations, spati…

Coral reefs harbor a large portion of marine biodiversity but are declining rapidly. Conservation efforts rely on monitoring coral abundance and composition as predominant indicators of ecosystem health and management success. However, manual monitoring o…

The goby genus Oxyurichthys (Gobionellinae) currently comprises 21 recognized species distributed across the tropical Indo-West Pacific region, with 12 species inhabiting the Western Indian Ocean (WIO). A recent examination of specimens from a mudflat hab…

MotivationHere, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubl…

Coral reefs are vital for biodiversity, coastal protection, food security, and tourism, yet they face severe threats from anthropogenic activities and climate change, which are leading to their decline. Effective coral reef monitoring is essential for eco…

Understanding the biological connections between populations is essential to wildlife management and conservation. Genetic studies play a central role in characterizing these connections, but typically require stratified sampling regimes to assess the spa…

In the South Pacific Convergence Zone (SPCZ), interannual to interdecadal oceanic and atmospheric variability is especially pronounced. The El Niño Southern Oscillation and the Interdecadal Pacific Oscillation significantly influence the SPCZ diagonal axi…

Context The French Pacific Island territories are home to an exceptional terrestrial biodiversity that is threatened by invasive alien rodents causing drastic ecological damage, including the decline of endemic species. Aims This study compiled and analys…

Integrating multiple lines of evidence that support molecular taxonomy analysis has proven to be a robust method for species delimitation in scleractinian corals. However, morphology often conflicts with genetic approaches due to high phenotypic plasticit…

Humpback whale song is a culturally transmitted behavior. Human language, which is also culturally transmitted, has statistically coherent parts whose frequency distribution follows a power law. These properties facilitate learning and may therefore arise…

Raising awareness among coastal communities is a key step in promoting the conservation and protection of aquatic ecosystems, particularly coral reefs.

To ensure that management measures for marine areas and species are appropriate and properly applied, key stakeholders and local realities must be taken into account. New Caledonia's local authorities are experimenting with different approaches to tailor …

Mangrove crab fishing has long been a secondary economic sector in Madagascar. But the situation has changed dramatically since 2014 with the expansion of live crab exports to the Asian market, which have boosted fishing effort and production.

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.

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.

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.

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.

Madagascar is renowned for its wide range of aquatic organisms, particularly crabs, octopus and fish. The latter are particularly abundant and are sold in a variety of forms (fresh, salted, smoked or dried) and sizes, ranging from large to small individua…

La sensibilisation des populations littorales est une étape clé pour favoriser la conservation et la protection des écosystèmes aquatiques, en particulier les récifs coralliens.

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.

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…

L'urbanisation, la surexploitation des ressources, les pollutions, la destruction des habitats et le changement climatique sont responsables de la sixième extinction massive d'espèces. Un phénomène global que les scientifiques tentent de quantifier au mie…

La pêche du crabe de mangrove est longtemps restée un secteur économique secondaire à Madagascar. Mais la situation a nettement évolué depuis 2014 avec le développement des exportations de crabes vivants vers le marché asiatique, qui ont fait bondir l'eff…

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.
