[Effect of a model of the H-component of a typical magnetic storm on early ontogenesis in Daphnia magna Straus].

The effect of a model of the H-component of a typical magnetic storm on the early ontogenesis of Daphnia magna Straus at 21 and 23 degrees C has been studied. It was shown based on the rates of the early ontogenesis that the effects of the model magnetic storm from the sudden onset of the storm to its end differ from the effects of the model magnetic storm from the recovery phase to the end of the storm. The effects of the model magnetic storm depended on temperature. The action of the model magnetic storm from the sudden onset of the storm to its end led to changes in the body length in the first progeny broods.

[Seasonal differences in the regeneration of planarians subjected to long-term electromagnetic shielding].

It has been found that the regeneration of planarians is most intensive in summer and least intensive in winter. In spring and autumn, the index of regeneration and the velocity of movement are higher than in winter but lower than in summer. Long-term electromagnetic shielding modifies the intensity of regenerative processes, and this effect is season-dependent. The stimulation is most clearly pronounced in winter and least pronounced in sommer and decreases with increasing duration of shielding. In spring, only a tendency to the stimulation of regeration is observed, which increases with the length of the observation period.
