Regulation of nasal heat exchange in reindeer

Regulation of brain temperature in winter-acclimatized reindeer under heat stress.

Reindeer (Rangifer tarandus) are protected against the Arctic winter cold by thick fur of prime insulating capacity and hence have few avenues of heat loss during work. We have investigated how these animals regulate brain temperature under heavy heat loads. Animals were instrumented for measurements of blood flow, tissue temperatures and respiratory frequency (f) under full anaesthesia, wherea...

Thermal windows and heat exchange

Endothermic animals, such as birds and mammals, regulate their body temperature balancing the amount of heat metabolically produced and that exchanged with the environment. Thus, whenever ambient temperature rises and/or metabolic heat production increases (such as during exercise), adjustments to promote heat dissipation are activated to defend body temperature. One of such adjustments modulat...
