Abstract
    The change in reproductive mode from parthenogenesis to gametogenesis in Cladocera is controlled by multiple environmental cues. Maternal effects are involved in the control of reproductive switching. In this study, we estimated the readiness of Moina macrocopa females to change reproduction mode under the effect of conspecific chemicals on maternal and offspring generations. The results demonstrated that information about the chemical environment was not transmitted between generations (none of the females produced diapausing eggs in the control medium irrespective of their mothers' environment). Differences in maternal energetic investments were not significant, hence the maternal environment did not affect the fecundity. However, tested animals adapted to the effect of the diapause inducing factor. When offspring of mothers cultured in crowded water were also cultured in crowded water (the constant effect of conspecific chemicals), they switched less readily to gametogenesis than offsprings of mothers cultured in fresh medium.
