Effect of dietary protein level on growth and energy utilization by Litopenaeus stylirostris under laboratory conditions

A study was conducted using a bioenergetics approach to generate information on energy requirement and feed utilization of Litopenaeus stylirostris. Animals (initial mean weight 21 +/- 1 g were fed ad libitum six experimental diets, ranging from 25 t...

Inferring the heterogeneity, transmissivity and hydraulic conductivity of crystalline aquifers from a detailed water-table map

Estimating the transmissivity or hydraulic conductivity field to characterize the heterogeneity 10 of a crystalline aquifer is particularly difficult because of the wide variations of the 11 parameters. We developed a new approach based on the analys...

Le référentiel taxonomique Florical et les caractéristiques de la flore vasculaire indigène de la Nouvelle-Calédonie

The taxonomic reference base Florical and characteristics of the native vascular flora of New Caledonia. The floristic inventory presented here comprises the evolving computerised database Florical (http://www.botanique.nc/herbier/florical). As of th...

Conservation priorities in a biodiversity hotspot : analysis of narrow endemic plant species in New Caledonia

New Caledonia is a global biodiversity hotspot facing extreme environmental degradation. Given the urgent need for conservation prioritisation, we have made a first-pass quantitative assessment of the distribution of Narrow Endemic Species (NES) in t...

Inferring the heterogeneity, transmissivity and hydraulic conductivity of crystalline aquifers from a detailed water-table map

Estimating the transmissivity or hydraulic conductivity field to characterize the heterogeneity 10 of a crystalline aquifer is particularly difficult because of the wide variations of the 11 parameters. We developed a new approach based on the analys...

Simultaneous combined XRF-XRD analysis of geological sample: New methodological approach for on-site analysis on New-Caledonian Ni-rich harzburgite

There is a growing interest in on-site, real-time analytical solutions for mining and environmental projects to characterize large areas and/or volumes of raw materials that are sometimes highly heterogeneous in terms of elemental distribution and mi...

Assessment of tropical shrimp aquaculture impact on the environment in tropical countries, using hydrobiology, ecology and remote sensing as helping t...

After a period of rapid development of the sites (an increase in both reared surface area and production), tropical shrimp aquaculture is currently being faced with critical problems due to economical and ecological constraints. In many countries wit...

Experimental exposures of native plants of the Goro region to SO2

En décembre 2010 un phénomène de dépérissement d'arbres a été observé dans une forêt adjacente à la limite Ouest des installations industrielles de l'usine Vale Nouvelle-Calédonie (VNC). La zone concernée est une formation riv...
