- Аннотация: Aiming to answer the question of how the rest-activity cycle and subcutaneous temperaturechange with a decrease in ambient temperature, we studied the following species of predatory mammals:domestic cats (Felis catus, n = 4), Far Eastern forest (Amur) cats (Prionailurus bengalensis euptilura,n = 3), Eurasian lynxes (Lynx lynx, n = 3), sables (Martes zibellina, n = 3), and forest ferrets/furo(Mustela putorius, n = 3). All subjects were studied in spacious forested area enclosures. Subcutaneoustemperatures in the interscapular region of the back as well as locomotor activity were recorded during70 days using miniature data loggers in the autumn–winter period (air temperature fluctuated from 12to − 20 °C). The results show different responses to natural cold: (1) a circadian rise in subcutaneoustemperature which is not associated with an increase in locomotor activity (Amur cats); (2) a circadianrise in subcutaneous temperature which correlates with an increase in locomotor activity (lynxes, domesticcats); (3) rises in subcutaneous temperature which correlate with increases in locomotor activity, but arenot circadian (sables, ferrets). The results demonstrate different strategies for adapting to natural cold invarious predatory mammals in conditions of captivity
