The rate of oxygen consumption in all developmental stages of two benthic cyclopoid copepod species, Acanthocyclops viridis (Jurine) and Eucyclops agilis (Koch, Sars) was investigated at temperatures between 5° C-20° C, which are reflective of the environmental temperature range of the benthic zone in Esthwaite Water, Cumbria, from which the organisms were derived. The larger species, A. viridis was found to have a temperature insensitive metabolism, whereas E. agilis showed a marked temperature response in respiratory function. Gravid and non-gravid females had similar rates of respiration except at 15° C-20° C in E. agilis. Males exhibited much lower respiration rates than females, but higher weight specific respiration rates; these differences were largely attributable to size differentials between the sexes. Estimates of swimming activity were made and these were related to the patterns of respiratory function observed. © 1985 Springer-Verlag.
