American Pikas

American Pikas. Pikas are small rabbit-like animals that live high in the mountains on rocky, talus slopes in the Great Basin. Warming here has contributed to the extinction of 7 of 25 populations of these animals. They are very sensitive to temperature changes and have no where to migrate to.

Presentation Transcript

  1. American Pikas • Pikas are small rabbit-like animals that live high in the mountains on rocky, talus slopes in the Great Basin. • Warming here has contributed to the extinction of 7 of 25 populations of these animals. • They are very sensitive to temperature changes and have no where to migrate to. (Jensen)

  2. Bighorn Sheep • Bighorn sheep face the same problem that pikas face; they also live high in the mountains and have no where to go in order to find similar temperatures The pika and bighorn sheep are a good indication of how global warming is affecting animals because they do not suffer a lot of direct human impact. The terrain is either protected or too rough for people. (Jensen)

  3. Butterflies • Different species of butterflies in both the western US and Europe are expanding their ranges north • 2/3 of 57 species of European butterflies have moved their ranges as far as 240 km in the 20th century (Jensen)

  4. American Alligators • American alligators range from the Carolinas south to Florida and west to Texas. • They are appearing further north than before • Rising sea levels could force them even further inland. (Tangley)

  5. Snails, Sea Stars, and other Intertidal Animals • In Monterey Bay, CA, the ranges of intertidal invertebrates has been shifting northward for the past sic decades as sea and air temperatures rise (Tangley) Back to Student 10 Home
