Tropical plant communities modifiy soil aggregate stability along a successional vegetation gradient on a Ferralsol

Soil aggregate stability is viewed as a promising indicator of the restoration status in eroded ecosystems, where the change in plant community composition through successional dynamics is a key driver of ecosystem restoration. In many tropical regio...

Ultra-violet radiation has a limited impact on seasonal differences in the Acropora muricata holobiont

Environmental conditions are known to influence corals and their associated communities of microorganisms. However, our insights into the impacts of seasonal changes in ultraviolet radiation (UVR) on both coral physiology and microbiome remain very l...

Twenty years after Jaffre et al. (1998), is the system of protected areas now adequate in New Caledonia ?

Protected areas are the cornerstone on which conservation strategies are often built. Adapting systems of protected areas to rapid global changes is critical to meet the challenge of conservation in biodiversity hotspots. Twentyyears ago, Jaffre et a...

The dynamics of institutional innovation : crafting co-management in small-scale fisheries through action research

This paper investigates the dynamics of institutional development and co-management performance in smallscale fisheries. The study covers different contexts and spatial and temporal scales, for nine case studies in the South Pacific. In these cases, ...

Assessment method of the sea turtle-nesting habitat of small reef islands

The coral islets in the lagoon of New Caledonia are a major breeding and nesting site for various species. Many species reproduce and nest there, whether they are Chelonians (green turtles and loggerhead turtles), ofshore seabirds (Procellariidae: sh...
