American Pika (Ochotona princeps)also called mouse hare and rock rabbit Species Code: OCPR What they look like: American Pikas are hearty small mammals who live in rock piles in the mountains of western North America. Pika are herbivores that maintain a high basal metabolic rate and high body temperature as adaptations to living at high elevations in the mountains where temperatures are cold. CQ15: American pika are small mammals that are related to rabbits and usually live above the tree line in the mountains of western North America. Author information: (1)Department of Biological Sciences, Vanderbilt University, 465 21st Ave South, Nashville, TN, 37235, USA. It is about 6 to 8 inches long, has round ears, and has no tail. The American pika is diurnal. The American pika (Ochotona princeps) is a good example of behavioral flexibility, according to Beever and team. The pika has thick warm fur. The American pika (Ochotona princepsoffers) a unique study system in which to study inter-population variation in gut micro-bial communities, as well as adaptations to herbivorous diets. Territory size can vary from 410–709 m² and is dependent on configuration, distance … The American pika may look closer to a mouse, but it is more closely related to the rabbit family. Pikas and Climate Change Related to rabbits and hares and adapted to high-elevation habitat, the American pika faces a bleak future as temperatures rise and snow cover disappears (3:02) Habitat of the Pika Though there is a wide variety of species, all are adapted to life in cold climates. Awesome Adaptations: American Pika. They are related to rabbits but are are about the size of large hamsters. Pika, (genus Ochotona), small short-legged and virtually tailless egg-shaped mammal found in the mountains of western North America and much of Asia. The American pika lives in the northwestern United States, while the collared pika lives in parts of Alaska and northwestern Canada. Action timeline . Vulnerability of pika … Despite their small size, body shape, and round ears, pikas are not rodents but the smallest representatives of the lagomorphs, a group otherwise August 21, 2007 – The Center petitioned the California Fish and Game Commission to list the five subspecies of American pika occurring in the state as endangered under the California Endangered Species Act.. October 1, 2007 – The Center filed a petition with the U.S. Gut microbial communities of American pikas (Ochotona princeps): evidence for phylosymbiosis and adaptations to novel diets. The American pika has found a way to live in the steep rockpiles high in the mountains. For alpine mammals, metabolic heat production and cellular mechanisms to cope with hypoxia are critical for survival and reproduction. Kohl KD(1,)(2), Varner J(3), Wilkening JL(4), Dearing MD(2). The species is typically limited to moist, rocky habitats at high-elevations in … The American pika (Ochotona princeps) is a small, winter-active mammal inhabiting alpine environments. The American pika tolerates cold climate environments through physiological and behavioral adaptations which may make them sensitive to even mildly warm climates. Fish and Wildlife Service to list the American pika under the federal Endangered Species Act. Pikas are high-elevation, alpine specialists, resulting in isolated “sky is-land” populations, with limited dispersal and population mixing The total area of land that an American pika uses is known as a home range.
