Abstract
The time course of intraperitoneal body temperature has been analyzed in two species of mammals (laboratory C57Bl/6 mice and white-breasted hedgehogs (Erinaceus roumanicus) and in two species of passerine birds (common greenfinch Chloris chloris and Japanese quail Coturnix japonica) with different body weights. Similar sets of basic harmonics appearing synchronously in different individuals have been found in the body temperature spectra of the species studied. The level of basal metabolism in those animal species considerably vary; therefore, the period of fluctuations of body temperature in the range of 10-120 min is not determined by the internal characteristics of the body and, presumably, reflects the influence of an external biotropic environmental factor.
