Thermoregulation in the pigeon Columbia livia during the stress produced by food deprivation

摘要: It has been established that development of nocturnal hypothermia in pigeons as the main strategy survival during food deprivation-produced stress is due to more significant than control (with unlimited consumption) inhibition thermoproduction course contractile and possibly non-contractile thermogenesis, well a small increase heat loss through skin open body parts. The dominating factors exit from fasting are earlier stronger (as compared with control) activation thermogenesis long peripheral vasoconstriction leading reduction loss. suggested be an additional adaptive mechanism alongside decrease brain temperatures; this promotes saving energy expenditure fasting-produced stress.
