[Endogenous biorhythms of the oxygen consumption rate in individual development of Lymnaea stagnalis (Lymnaeidae, Gastropoda)].

Two endogenous biorhythms of the oxygen consumption rate with periods of 10.3 and 7.2 weeks have been revealed in the late postlarval ontogenesis of freshwater gastropods Lymnaea stagnalis by singular spectrum analysis. It has been determined that local maxima of both biorhythms in different individuals occur at the same age; in addition to that, the… CONTINUE READING
