Can we use the planation surface concept to reconstruct the morphogenesis of New Caledonia,? First low temperature thermochronological data

Nickel ore deposits of New Caledonia are formed in thick laterites and ferricretes developed on peridotites. Formation of this regolith remains unclear but combines stable phases with weathering profile development and preservation and mobile phases ...

Response of the blue shrimp Litopenaeus stylirostris to temperature decrease and hypoxia in relation to molt stage

The effect of different levels of dissolved oxygen (DO) and a decreased temperature combined with severe hypoxia were studied in the blue shrimp Litopenaeus stylirostris in relation to molt stage. In the first experiment, shrimps were submitted to DO...
