Spatial management of inshore areas: Theory and practice

Coastal uses have deeply evolved these last decades and high anthropogenic pressures on coastal ecosystems have affected the sustainability of these areas with respect to the services and the resources they may provide. Traditional fisheries manageme...

Physiological response of the blue shrimp Litopenaeus stylirostris to short-term confinement on a pond bottom

The blue shrimp Litopenaeus stylirostris was exposed to pond sediment for 48 h and its physiological response was studied in relation to molt stage. Shrimp were maintained in cages within a semi-intensive pond after 4 months of rearing. Hypoosmoregul...

Floating cages as an experimental tool for shrimp culture studies: first attempts to check their reliability

The first aim of this study was to evaluate on a technical basis the rearing of shrimps in floating cages set up in earthen ponds. Shrimps reared in and outside the cages presented comparable growths and survival rates. Then it was concluded that shr...

Animal leptospirosis in small tropical areas

Leptospirosis is the most widespread zoonosis in the world. Humans become infected through contact with the urine of carrier animals, directly or via contaminated environments. This review reports available data on animal leptospirosis in ten tropica...

Measuring development trough public policy evaluation? The case of the North Province in New Caledonia

Policies designed for sustainable development are becoming ever more complex and ambiguous. Assessments should thus incorporate development representations and values, rather than only relying on economic and financial normative indicators. This pape...

Investigating the March 28th 1875 and the September 20th 1920 earthquakes/tsunamis of the Southern Vanuatu arc, offshore Loyalty Islands, New Caledoni...

New Caledonia's Loyalty Islands are located in the southwest region of the Pacific ocean in the highly seismogenic southern Vanuatu subduction zone and therefore may be subject to devastating local tsunamis. Over the past 150 years, two large tsunami...

On the Influence and Correction of Water Content on pXRF Analysis of Lateritic Nickel Ore Deposits in the Context of Open Pit Mines of New-Caledonia

In a number of applications, the use of portable X-ray fluorescence (pXRF) instruments offers a time and cost-saving alternative to standard laboratory instruments. This is particularly true in a mining context where decisions must be taken quickly i...

Acclimatization of massive reef-building corals to consecutive heatwaves

Reef-building corals typically live close to the upper limits of their thermal tolerance and even small increases in summer water temperatures can lead to bleaching and mortality. Projections of coral reef futures based on forecasts of ocean temperat...

SSDM : an R package to predict distribution of species richness and composition based on stacked species distribution models

1. There is growing interest among conservationists in biodiversity mapping based on stacked species distribution models (SSDMs), a method that combines multiple individual species distribution models to produce a community-level model. However, no u...
