Enhancement of coral calcification via the interplay of nickel and urease

Corals are the main reef builders through the formation of calcium carbonate skeletons. In recent decades, coral calcification has however been impacted by many global (climate change) and local stressors (such as destructive fishing practices and ch...

Quelle influence des symbioses mycorhiziennes et des traits racinaires sur l'érosion des sols tropicaux ? Application à la restauration écologique ...

Les écosystèmes forestiers tropicaux représentent près de la moitié de la superficie forestière mondiale. Ces écosystèmes qui fournissent des services fondamentaux pour le bienêtre de nos sociétés (e.g. régulation des flux de matières, m...

Towards a better integration of local populations in the design of projects to manage the massive aggradation of rivers stemming from mining activity ...

Nickel mining in New Caledonia has largely contributed to the supply of sediment to watercourses, so that some of the main watercourses of the island are considerably aggraded. One of the consequences of this massive aggradation is the elevation and ...

An optimised passive acoustic sampling scheme to discriminate among coral reefs' ecological states

In the present era of rapid global change, innovative monitoring methods can greatly enhance our ability to detect ecological disturbances and prioritise conservation areas in a timely and cost-effective manner. While Passive Acoustic Monitoring (PAM...

Disentangling the processes driving tree community assembly in a tropical biodiversity hotspot (New Caledonia)

Aim: Understanding the drivers of community diversity and composition is a major question in ecology, which is of particular significance for the conservation of narrowly distributed taxa facing habitat alteration. In this study, we examined three ec...

Potential of high-throughput eDNA sequencing of soil fungi and bacteria for monitoring ecological restoration in ultramafic substrates: The case study...

Due to their central role in ecosystems functioning and their ability to rapidly respond to environmental changes, soil microorganisms could potentially be used for monitoring ecosystems recovery in the context of degraded land restoration. However, ...

Effects of ultramafic topsoil stockpiling during mine activities on its microbial diversity and other microbiological and physicochemical characterist...

Nowadays, ecological restoration is considered the best solution for the rehabilitation of mining-degraded areas, particularly when it concerns valuable ecosystems. This is the case in New Caledonia, a hot spot of biodiversity, with 82% of endemic pl...

Nickel mining in New Caledonia has largely contributed to the supply of sediment to watercourses, so that some of the main watercourses of the island are considerably aggraded. One of the consequences of this massive aggradation is the elevation and ...

Biodiversité et conservation

la nouvelle calédonie est une région d'une très haute endémicité aussi bien faunistique que floristique. ce rapport démontre cette particularité à travers la description de son environnement historique, géologique, géographique et de plusie...

Synthèse des connaissances sur les impacts environnementaux de la pollution lumineuse en Nouvelle-Calédonie

Lauréat du programme européen BEST 2.0+, le projet Pollux NC a été lancé le 7 juillet 2021 pour une durée de 16 mois. Son objectif : fournir les premières informations quantifiées sur la pollution lumineuse à l'échelle de la Nouvelle-Caléd...
