ACTIVITY PATTERNS AND FORAGING BEHAVIOR OF AMERICAN PIKAS (OCHOTONA
PRINCEPS) DIFFERS BETWEEN CRATERS OF THE MOON AND ALPINE TALUS IN IDAHO.
Sable mainly hunt for small animals, but it also preys on larger mammals such as chipmunks Tamias sibiricus, pikas Ochotona
, squirrels Sciurus and Pteromys, muskrats Ondatra, marmots Marmota, mountain hares, and musk deer Moschus moschiferus (Moskov 1973, Khlebnikov 1977, Monakhov and Bakeyev 1981, Zirjanov et al.
More substantial accumulation of rocks is required by some other mammalian species, e.g., pikas (Ochotona
spp.) in talus of western North America (MacDonald and Jones, 1987; Smith and Weston, 1990) and the mountain pygmy possum (Burramys parvus) in alpine periglacial boulder fields of southeastern Australia (Menkhorst et at, 2008).
The phylogeographic predictions of the strict cospeciation and episodic host-switching models were tested using the North American pika/parasite assemblage, with a primary focus on the American pika, Ochotona
princeps (Richardson, 1828), and a suite of its endoparasitic cestodes and nematodes.

Other "[potential climate refugees include the American pika (Ochotona
princeps), bighorn sheep, red wolves (Cards lupus rufus), San Bernardino flying squirrels (Glaucomys sabrinus calif amicus'), Quino checkerspot butterflies (Euphydryas editha quino), and white bark pine (Pinus albicaulis Zellmer, supra note 21, at 341.
Geographical variation of skull characters in pikas (Ochotona

Plateau pika (Ochotona
curzoniae) is a species of small mammals in the Ochotonidae.
For example, Kreuzer and Huntly (2003) used a similar measurement (rate of disappearance) to signify maximum mortality in a mark-recapture study of population dynamics of the American pika (Ochotona
This paper will focus on several of the many North American wildlife species responding to climate change including the loggerhead sea turtle (Caretta caretta), the pika (Ochotona
princeps), and the purple finch (Carpodacus purpureus).
This loss of alpine tundra will decrease the success of obligate tundra species such as hoary marmot (Marmota caligata), collared pika (Ochotona
collaris), and ptarmigan (Lagopus sp.) (Martin, 2001).
