Abstract

The dependence of Daphnia magna's survival and fertility on a season and the water toxicity level was determined. It was also established that the survival rate does not depend on the season, but is directly related to the water quality, and such an indicator as fertility does depend on both the season and the water toxicity level. Seasonal fluctuations in the survival rate and fertility of Daphnia magna in laboratory culture were studied. Maximum and minimum levels of the fertility level within a year have been established. The relationship between the dynamics of the survival rate and fertility and seasonal changes was shown.
