The respiration rate (RR) of five species of mayfly from the Soviet Far East (Drunella aculea Allen, Cincticostella levanidovae Tshernova, Ecdyonurus dracon Kluge, Siphlonurus lacustris Eaton, Ameletus cedrensis Sinitshenkova) was measured in a closed respirometer and plotted against oxygen concentration (OC). Except A. cedrensis, all aspecies were able to maintain RR at a constant level over certain ranges of OC by regulation with respiratory movements. In contrast, the RR of A. cedrensis dropped continuosly as OC in the water declined, the species being a conformed. These differences are interpreted in the light of microhabitats occupied by the species in the fild.
