L'immensité du parc naturel de la mer de Corail cache des territoires mystérieux et fascinants, encore largement inexplorés. Héritiers de l'histoire géologique complexe de la région, ils abritent une diversité remarquable de paysages invisibles depuis l…

L'océan est un espace à forte valeur patrimoniale pour tous les Calédoniens. Pour les Kanak, il est essentiel en raison de sa richesse en faune et en flore et il se situe au coeur de la conception du monde et de l'organisation des sociétés. Plus large…

Isolés dans l'immensité du Pacifique Sud, les îles et îlots du parc naturel de la mer de Corail abritent une biodiversité exceptionnelle et de remarquables vestiges, aussi précieux que fragiles. Ces terres émergées, pourtant minuscules, concentrent d'i…

Baleines, requins, oiseaux, tortues, thons... la faune qui peuple le parc naturel de la mer de Corail, depuis les profondeurs marines jusqu'aux récifs, est remarquable à bien des égards. Cette biodiversité exceptionnelle ne se résume pas à une simple li…

Colorés et d'une grande beauté, les récifs coralliens du parc naturel de la mer de Corail forment de véritables forêts sous-marines. Ces univers complexes, encore large- ment méconnus, abritent une biodiversité exceptionnelle, où chaque élément structur…

Petite portion de l'océan Pacifique, le parc naturel de la mer de Corail est traversé par de puissants courants océaniques et des turbulences qui lui confèrent un caractère dynamique et impétueux. Bien que cet immense océan calédonien soit extrêmement p…

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.
