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. They are related to rabbits but are are about the size of large hamsters. Territory size can vary from 410–709 m² and is dependent on configuration, distance … Author information: (1)Department of Biological Sciences, Vanderbilt University, 465 21st Ave South, Nashville, TN, 37235, USA. 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) It is about 6 to 8 inches long, has round ears, and has no tail. Habitat of the Pika Though there is a wide variety of species, all are adapted to life in cold climates. Pikas are high-elevation, alpine specialists, resulting in isolated “sky is-land” populations, with limited dispersal and population mixing Action timeline . Despite their small size, body shape, and round ears, pikas are not rodents but the smallest representatives of the lagomorphs, a group otherwise The total area of land that an American pika uses is known as a home range. Vulnerability of pika … Gut microbial communities of American pikas (Ochotona princeps): evidence for phylosymbiosis and adaptations to novel diets. 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. The American pika has found a way to live in the steep rockpiles high in the mountains. The American pika (Ochotona princeps) is a small, winter-active mammal inhabiting alpine environments.
