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 ...
Reindeer occur in both migratory and sedentary populations, and their herd sizes vary greatly in different regions. The tundra subspecies are adapted for extreme cold, and some are adapted for long-distance migration. Reindeer vary greatly in size and color from the smallest, the Svalbard reindeer (R. (t.
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature.
