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.
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 ...
These plants are adapted to short, cold growing seasons. [1] They have the ability to withstand extremely cold temperatures in the winter (winter hardiness), and grow and reproduce in summer conditions that are quite limiting. As of 2005, arctic vegetation covered approximately 5 × 10 ^ 6 km 2 (1.9 × 10 ^ 6 sq mi) of land. [2]

In this state, they save energy during cold weather while they have limited access to food sources.
