CHEMICAL BASIS OF STABLE ELEMENTS FOR THE BIOLOGICAL SIGNAL FIELD OF MARMOTS

Chemical substances of the skin glands secretion products, of excrements and their decomposition products create the chemical basis of stable elements for the biological signal field of marmots. The chemical composition of the volatile substances that could be stable elements and form olfactory image of the territory inhabited by marmots is discussed. Uneven accumulation of these substances in the soil cover (related to the probability of leaving a scent trail by rodents) creates gradients of the biological signal field facilitating the orientation in the space for marmots.
