Arctic foxes and gray wolves maintain their foot temperature just above the tissue freezing point (about -1�C)when standing on extremely cold snow, or when the foot is immersed in a -35�C bath in the laboratory. Proportional thermoregulation stabilized the subcutaneous temperature of the foot pad to a precision of � 0.7�C (largest deviations). Selective shunting of blood-borne body heat through a cutaneous vascular plexus in the foot pad accounted for more than 99 percent of measured heat loss…

Thermoregulation in resting and active polar bears
  • R. C. Best
  • Environmental Science
    Journal of comparative physiology
  • 2004
SummaryPolar bears (Ursus maritimus) regulate their body temperatures both physiologically and behaviourally proportional to their level of activity while within the thermoneutral zone. Core…
Adaptation by the Arctic Fox ( Alopex lagopus ) to the Polar Winter
In this article physiological, behavioural and morphological adaptations by the arctic fox to low temperatures and food scarcity in winter are discussed. The arctic fox ( Alopex lagopus ) adapts to…
An Infrared Thermographic Study of Surface Temperature in Relation to External Thermal Stress in Three Species of Foxes: The Red Fox (Vulpes vulpes), Arctic Fox (Alopex lagopus), and Kit Fox (Vulpes macrotis)
Temperatures of different body surface regions of unrestrained adult red, arctic, and kit foxes exposed to ambient temperatures (Ta) ranging from -25° to 33° C were measured by infrared (IR)…
Vascular responses to temperature in the foot of the giant fulmar,Macronectes giganteus
TLDR
Blood circulation to the leg of an antarctic bird, the giant fulmar, has been studied in response to changing the temperature of the ambient environment including immersion of the feet in ice water, which elicited an immediate flow increase and a transient increase in foot arterial blood temperature.
Response to cold in the blue fox and raccoon dog as evaluated by metabolism, heart rate and muscular shivering: a re-evaluation.
Terrestrial Mammals in Cold
TLDR
In addition to making seasonal adjustments, mammals that reside in cold-dominated regions such as the arctic may show climatic adaptations which distinguish them from mammals at lower latitudes.
Adaptations to polar life in mammals and birds
  • A. S. Blix
  • Environmental Science
    Journal of Experimental Biology
  • 2016
TLDR
Polar animals are well adapted to the hardships of polar life, particularly when the sun never sets in summer and darkness prevails during winter, high-latitude animals become intermittently active around the clock, allowing opportunistic feeding at all times.
Some general characteristics of temperature regulation
Seasonal changes in the relative importance of different avenues of heat loss in resting and running reindeer.
TLDR
It is suggested that in the running reindeer the body surface is an effective avenue of heat loss during summer, while heat dissipation by way of the respiratory tract attains increased importance in winter, when fur insulation is at its best.
Heterothermic Operation of Homeotherms
As generators of heat with well sustained internal operating temperatures, birds and mammals maintain thermal gradients from the interior to surrounding cold air or water. I will forego discussion of…
