"Horizontal" and "vertical" diffusion : the cumulative influence of Impact and Benefit Agreements (IBAs) on mining policy-production in New Caledonia

The scale, duration and intensity of conflicts over mineral resources vary greatly. However, they always involve, in varying proportions, the triad stakeholder model corporation, state, community each element of which is internally heterogeneous. Inc...

Inferring savannah-rainforest boundary dynamics from vegetation structure and composition : a case study in New Caledonia

A direct consequence of deforestation and forest fragmentation in the tropics is the increased importance of boundaries between forest fragments and savannahs. These boundaries are critical zones for understanding the dynamics of savannahs and forest...

Combined effect of temperature and salinity on osmoregulation of juvenile and subadult Penaeus stylirostris

In New Caledonia, the "syndrome 93," which results in mass mortalities of farmed shrimp Penaeus stylirostris, occurs during the transitional and the cold seasons. The transitional season is characterized by an important fall in the average water temp...

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...

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...

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...

Thermotolerance adaptation to human-modified habitats occurs in the native range of the invasive ant Wasmannia auropunctata before long-distance dispe...

Key evolutionary events associated with invasion success are traditionally thought to occur in the introduced, rather than the native range of species. In the invasive ant Wasmannia auropunctata, however, a shift in reproductive system has been demon...

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...
