Nous voilà confrontés aux extrêmes de la conscience : d'un côté, ce sentiment de toute-puissance, puissant levier de la négation des limites ; de l'autre, cette perception accrue de notre appartenance au vivant, et donc de notre fragilité, qui encourage à repenser de manière plus raisonnée notre inscription dans les écosystèmes, mais peut aussi ent...
Biological N-2 fixation rates were quantified in the Eastern Tropical South Pacific (ETSP) during both El Nino (February 2010) and La Nina (March-April 2011) conditions, and from Low-Nutrient, Low-Chlorophyll (20 degrees S) to High-Nutrient, Low-Chlorophyll (HNLC) (10 degrees S) conditions. N-2 fixation was detected at all stations with rates rangi...

Batch cultures of Trichodesmium erythraeum, strain IMS101, and Crocosphaera watsonii, strain WH8501, were grown under metal- and vitamin-replete conditions to evaluate differences in diazotroph abundance and N-2 fixation rates as well as biomass C:N:P ratios resulting from changes in the concentrations of nitrate (NO3-) and phosphate (PO43-) in cul...
