High-fiber Salad Bar May Help Roly-poly Pikas Survive Climate Change
2013-12-18 13:58:16

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...

Unusual Co-operation Between Species In Competition For Scarce Vegetation In Northern Mountain Areas
2013-04-25 15:44:10

Who would have thought that two very different species, a small insect and a furry alpine mammal, would develop a shared food arrangement in the far North? University of Alberta researchers were certainly surprised when they discovered the unusual response of pikas to patches of vegetation that had previously been grazed on by caterpillars from a species normally found in the high Arctic. U of A biology researcher Isabel C. Barrio analyzed how two herbivores, caterpillars and pikas,...

University of Alberta researchers were certainly surprised when they discovered the unusual response of pikas to patches of vegetation that had previously been grazed on by caterpillars from a species normally found in the high Arctic. U of A biology researcher Isabel C. Barrio analyzed how two herbivores, caterpillars and pikas, competed for scarce vegetation in alpine areas of the southwest Yukon. The caterpillars come out of their winter cocoons and start consuming vegetation soon after...

Southern Rocky Mountain Pikas Holding Their Own
2011-09-01 13:01:37

  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...

Local extinction rates of American pikas have increased nearly five-fold in the last 10 years, and the rate at which the climate-sensitive species is moving up mountain slopes has increased 11-fold, since the 20th century, according to a study soon to be published in Global Change Biology. The research strongly suggests that the American pika's distribution throughout the Great Basin is changing at an increasingly rapid rate. The pika (Ochotona princeps), a small, hamster-looking animal...

Rock formations buffer pika from warming temperatures New research addressing climate change questions, a priority focus of the USDA Forest Service Pacific Southwest Research Station, documents that American pika in the Sierra Nevada and southwestern Great Basin are thriving and persist in a wider range of temperatures than previously discovered. Results were recently published in a paper titled "Distribution and Climatic Relationships of the American Pika (Ochotona princeps) in the Sierra...

Although not ready for the endangered species list, the American pika will be watched closely by federal scientists who feel the warming climate trend in the West over the next few decades could potentially threaten the climate-sensitive mammal. The U.S. Fish and Wildlife Service formally announced its decision on Friday that the American pika, a small mountain-dwelling relative of the rabbit, would not be listed on the Endangered Species Act. The agency does admit, though, that not much is...

The first-ever study of its kind could help determine if the American pika is at risk of disappearing from western U.S. mountain tops, scientists say. The pika, a 7-inch-long relative of the rabbit, is found in alpine and sub-alpine areas, where their one-note squeak is considered a signature sound of the rocky landscapes, said Connie Millar, a U.S. Forest Service scientist who studies pika populations. The U.S. Fish and Wildlife Service has said it will decide by February whether to list the...

A minute mammal that needs cold weather to survive may become the first animal in the lower 48 states to get Endangered Species Act protection specifically for the reason of the climate change. The U.S. Fish and Wildlife Service, answering a petition sent by environmentalists, announced Wednesday that they will start an in-depth appraisal of the American pika and present their notes by Feb. 1, 2010. The agency accepted that there is "substantial information" demonstrating that climate change...

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.
