It was established that the electric activity of slightly electric fish Gnathonemus leopoldianus and the motion activity of somiks Hoplosternum thoracatum and cockroaches Blaberus craniifer, which were kept in a thermally stabilized room, regularly change throughout the year. Changes in the activities of different species of animals are coordinated. In all of the cases, the activity maximum falls on the spring-summer period. Possible factors responsible for seasonal variations in the electric and motion activities are discussed, and their forms are compared with the character of seasonal variations in different geophysical processes.
