Physiological adaptations of the arctic fox to high Arctic conditions

Updated 2003-01-27

To investigate arctic foxes physiological adaptations to life at high latitudes. Resting and running metabolic rates, body weight, food intake, body core temperature, heart rate, and blood parameters were examined during different seasons and during periods of food deprivation.
