Résumé 1. Au cours de la mission Cineca I du «Jean Charcot», 281 estimations de la respiration à plusieurs températures ont été faites chez des copépodes récoltés à différentes profondeurs. 2. Les courbes métabolisme-température dénotent plusiers types d'adaptation aux conditions thermiques. 3. Il existe une corrélation forte entre le logarithme de la respiration et le logarithme du poids. Le coefficient de régression est différent selon la température envisagée. Il ne s'intègre aux limites données par la loi de surface qu'à la température de 18°C où il est maximum.
Notes:
Abstract The results of 281 respiration analyses of pelagic copepods sampled in the South Moroccan and Canarian area are described. The copepods used in experimentation were collected from various bathymetric levels: hyponeustonic species (Anomalocera patersoni, Pontellopsis villosa, P. regalis, Labidocera wollastoni, Pontella lo biancoi), epipelagic species (Centropages typicus, Temora stylifera, Calanus helgolandicus, Acartia clausi), meso and bathypelagic species (Pleuromma xiphias, P. abdominalis, Euchaeta acuta, Undeuchaeta plumosa and some other rare species). Analysis of the metabolismtemperature curve makes it possible to describe different modes of adaptation in relation to geographical distribution, altitudinal repartition, and dietary characteristics. When all species are studied together, a strong correlation exists between the log of respiration and the log of weight. The regression coefficient varies with temperature; it is strongest at a temperature near that of the natural thermic conditions.
