Reindeer have adapted to endure the cold and survive extreme winters. In North America, wild reindeer will seek shelter and tough out winter in forested areas. In the spring, when the days become ...
The mountain reindeer has several physiological adaptations to cope with different environmental temperatures. Reindeer have hemoglobin that allows for high oxygen unloading even at very cold temperatures. [1] This is essential because reindeer limbs are often kept much colder than core body temperature, a phenomenon known as regional ...
