New Study Shows Differences In Mammal Responses To Climate Change
2014-01-23 11:57:02

University of Colorado Boulder If you were a shrew snuffling around a North American forest, you would be 27 times less likely to respond to climate change than if you were a moose grazing nearby. That is just one of the findings of a new University of Colorado Boulder assessment led by Assistant Professor Christy McCain that looked at more than 1,000 different scientific studies on North American mammal responses to human-caused climate change. The CU-Boulder team eventually selected...

High-fiber Salad Bar May Help Roly-poly Pikas Survive Climate Change

University of Utah In some mountain ranges, Earth's warming climate is driving rabbit relatives known as pikas to higher elevations or wiping them out. But University of Utah biologists discovered that roly-poly pikas living in rockslides near sea level in Oregon can survive hot weather by eating more moss than any other mammal. "Our work shows pikas can eat unusual foods like moss to persist in strange environments," says biology professor Denise Dearing, senior author of the new...

Southern Rocky Mountain Pikas Holding Their Own

  Findings in contrast to recent study showing pika declines in the Great Basin American pikas, the chirpy, potato-sized denizens of rocky debris in mountain ranges and high plateaus in western North America, are holding their own in the Southern Rocky Mountains, says a new University of Colorado Boulder study. Led by CU-Boulder doctoral student Liesl Erb, the study team assessed 69 historical sites known to host pikas in a swath of the Southern Rockies ranging from southern...

The term pika is used to refer to small mammals in the Ochotonidae family, which holds one genus known as Ochotona. This genus holds thirty species, sometimes referred to as whistling hares, which can be found in cold areas of North America, Asia, and Eastern Europe. Most of the species within this genus reside in rocky areas, although some can be found in steppe environments. Pikas reach an average body length between 5.9 and 9.1 inches, with a weight of up to twelve ounces. They prefer...

The Northern Pika, Ochotona hyperborea, is a species of pika found across northern Asia, from the Ural Mountains to northern Japan and south through Mongolia, Manchuria, and northern Korea. There are several subspecies of this pika. An adult Northern Pika has a body length of 5 to 7.33 inches, and a tail less than a half inch. The pika sheds its fur twice annually, bearing a reddish-brown coat in the summer and grayish-brown in the winter.

The American Pika (Ochotona princeps) is a diurnal(active during day and sleeps at night) species of pika. It is found in the mountains of western North America. They are usually in boulder fields at or above tree line. A recent news article suggests that species populations are declining due to various factors. They are very sensitive to high temperatures. Pikas are considered to be one of the best early warning systems for detecting global warming in the western United States.
