Climate change affects the pikas in a few key ways. This dataset shows modelled habitat suitability for the Collared Pika (Ochotona collaris) under current and projected future conditions. The Mackenzie River in the NWT likely acts as a barrier on the eastern edge of its range.
The Collared pika is a key species that is consumed by numerous predators (ermines, weasels, foxes, owls, eagles). The role of habitat quality and climate in the dynamics of occupancy and survival of a population of collared pikas (Ochotona collaris) in the Ruby Range, Yukon Territory.
There is a greyish "collar" around the neck and shoulders. Their nape and shoulders have distinctive patches that form a collar, which is what affords the species the name of ‘collared’ pika. The high-elevation, high-latitude areas where they are mainly found are witnessing shifts in habitat and temperature at faster rates than elsewhere in Canada. We built habitat suitability models for 23 The word pika is derived from the Siberian name for this animal, puka. Loss of alpine habitat to tree and shrub encroachment may also reduce suitable habitat for pikas. MSc thesis, University of Alberta, Edmonton, AB, CAN.
Collared pikas impact grass and herbaceous plant species in their high elevation habitats. The ventral fur of a collared pika is creamy white, whereas the dorsal fur is a bit grayish.
DOI: 10.793 Hudson, J. M. G., S. F. Morrison, and D. S. Hik. [3] It is a small (~160 gram) alpine lagomorph that lives in boulder fields of central and southern Alaska (), [4] and in parts of Canada, including northern British Columbia, Yukon, and western parts of the Northwest Territories. 2008.
Why survey for pika? There are distinctive patches on the nape and shoulder forming a collar thus giving them their common name. Size: 18 - 20 cm (7 - 8 in); 130 g (4.5 oz). This dataset shows modelled habitat suitability for the Collared Pika (Ochotona collaris) under current and projected future conditions. Factors Affecting Habitat Occupancy by the Collared Pika, A Species at the Coal Face of Climate Change. In terms of their diets, collared pikas are almost pure herbivores. Collared Pika are restricted to talus slopes in alpine areas in Alaska, Yukon, western Northwest Territories, and northwestern British Columbia. This region is witnessing climate-driven shifts in habitat and temperature at faster rates than elsewhere in Canada.
Collared Pika. Pika are sensitive to climate Collared pikas inhabit the cold mountains of central and southern Alaska and also northwestern Canada, where they are found in scree and other rocky areas above the tree line. It is one of two pika species in North America, along with American Pika (O. princeps). Collared pikas (Ochotona collaris) and their southern counterparts, American pikas (Ochotona princeps), inhabit some of the most isolated and extreme environments of any mammal in North America. Their hay piles could provide food for other herbivorous mammals. The collared pika (Ochotona collaris) is the only species of pika found in Alaska. The collared pika (Ochotona collaris) is a species of mammal in the pika family, Ochotonidae, and part of the order Lagomorpha which comprises rabbits, hares, and pikas. Closely related to hares and rabbits, pikas are charismatic but lesser known members of the order Lagomorpha.
