[Trace reactions and ambient temperatures].

Experimental data obtained on thermoregulatory trace reaction at the organismic, organic and tissue levels divided the trace reactions into 3 groups: continuous or discontinuous influences of ambient temperatures leading to high organism tolerance--adaptations; combination of thermal stimuli with indifferent ones and the formation of conditioned thermoregulatory reflex; habituation--following either single or repeated thermal stimuli. Changes in temperature relations of tissue and organ metabolism (Q 10) on ambient temperature shifts both in experiment and in natural diurnal cycle are discussed as well as the patterns of trace reactions following different regimens of temperature stimulation of the organism.
