The pika, a small mammal that lives in talus slopes at high elevations in the mountains of the American West, has disappeared in the last decade at a rate five times faster than they disappeared during the 20th century, according to a study out this month.
. . .The species is also moving to higher elevations at a faster rate, more than 10 times as fast as previously observed, presumably to stay within its preferred temperature range. In the last 10 years, they have moved up nearly 500 feet in elevation.
Pikas are smarter than humans.
