Remarkable hypoxia and cold tolerance of rodents native to the Tibetan plateau

The plateau zokor (Eospalax baileyi) is an underground dwelling rodent species native to the Tibetan plateau (2000-4200 meters in elevation). A new study published in the¬†American Journal of Physiology – Regulatory, Integrative and Comparative Physiology¬†explored how these animals were adapted to extract oxygen from an environment with very low levels (83-88% of atmospheric).
