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.
But some species, especially those on mountains such as the American pika
, run out of room to move and may die off because there's no place to escape the heat, Urban said.
THE WARMING climate appears to be pushing populations of the American pika
, a small hamster-like rodent, towards extinction in the Great Basin in the western USA, according to a new study published in Global Change Biology.
The 90 miles of hiking trails in the park offer warmth through motion, and on my walk I hope to see an American pika
, a small mammal related to a rabbit, with teacup-like ears.
Fish and Wildlife Service recently declined to list it as endangered or threatened, the American pika
remains an excellent example.
Pika Protection In May, the American pika
became the first mammal in the continental United States to be considered for protection under the Endangered Species Act due to climate change.
The American pika
, a small rabbit-like animal, can be seen and heard in rocky talus slopes at higher elevations in the Cascade Mountains.
Revised parameter estimates are obtained for two species living in well-studied metapopulations: the American pika
(Ochotona princeps) at Bodie, California, and the false heath fritillary butterfly (Melitaea diamina) in the Tampere region in Finland.
That furry creature was a North American pika
(PIE-kuh) - a relative of rabbits and hares.
Further research revealed that both the Tibetan antelope and the highland American pika
have signals of positive selection for genes involved in DNA repair and the production of ATPase.
According to Jim Patton, a retired University of California Berkeley zoology professor, the tiny gray mammal's movement represents the greatest upward "retraction" of any high major-elevation species, which include the golden-mantled ground squirrel, the Belding ground squirrel, the water shrew, the bushy-tailed woodrat and the American pika
