The respiration rate of all stages of Cyclops bicuspidatus (s. str.) (Claus), a benthic copepod, from Esthwaite Water in the English Lake District, was determined at a range of field temperatures, 4° C-12° C, using cartesian diver microrespirometry. The population of C. bicuspidatus in Esthwaite Water was found to be adapted to low temperatures, with an optimum rate of metabolism at 8° C. Weight varied with temperature, in general the largest weights occurred at the lower temperatures. Adult males had higher rates of respiration than adult females, which were on average twice the size of males. Gravid and non-gravid females had similar levels of metabolism. Regression coefficients (b), derived from regressions of log oxygen consumption against log dry weight were low, ranging between 0.25-0.51 according to temperature. © 1980 Springer-Verlag.
