Abstract
The impact of alternating magnetic field (AMF) of ultralow and low frequencies during a sevenday-long exposure on Daphnia magna Straus was studied. It is shown that AMF may decrease the survival and the time it takes to reach sexual maturity. AMF with a frequency of 500 Hz has the most pronounced negative impact upon survival and maturation. AMF of 50 Hz accelerates maturation. In a chronic experiment at 500 Hz, the share of vital offspring increased, while the sizes of newborns decreased in parent specimens that matured under the impact of a magnetic field. The action of a 500 Hz AMF on daphnias before littering of offspring leads to an increase in the number of newborns in the reproductive period.
