L'évolution géochimique supergène des roches ultrabasiques en zone tropicale - Formation des gisements nickélifères de Nouvelle-Calédonie

Étude de l'évolution des roches ultrabasique en Nouvelle-Calédonie ayant mené à la formation des gisements nickélifères.

Atlas de Nouvelle-Calédonie - Hydrométrie

Cet article relate les informations relevées au travers du réseau de mesures géré par les services du gouvernement (22 stations). Il fournit des éléments sur les différents régimes hydrologiques, les étiages ainsi que les crues et inondation...

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...

"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...

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...

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, ...
