American PikaLatin name: Ochotona Princeps,
Conservsation status: least concern (population is decreasing)
Pikas, also called "whistling hares" because of their loud song, feed in winter on dried haypiles they have stored near the entrance to their burrows. When haying during late summer they may make up to 100 trips a day.
American pikas occupy talus—rock piles that accumulate at the base of a slope—at high elevations in western mountains. Pikas are thought to be a prime example of the potential effects of climate change because they are sensitive to warm temperatures and rely on insulation provided by snow to survive cold winter temperatures. However, several recent studies indicate that pikas can be resilient to each of these factors. Most pikas in the Sierra Nevada survived the winter of 2014, when there was almost no snowpack. Pikas persist in many hot localities as well, demonstrating their ability to cope with high temperatures.
Other animals effected by climate change
Before 1800 there were an estimated 10–20,000 Whooping Cranes in North America. By 1941, because of hunting and habitat destruction, there were fewer than 20. There are now approximately 350–380 in the wild. The wild Whooping Crane population has only one winter habitat—a wildlife refuge on the Gulf Coast in Texas; and one spring breeding habitat—a prairie wetlands in Alberta. Severe storms, sea level rise, drought, industrial development and oil spills threaten these habitats. Another significant threat to young Whooping Cranes is colliding with power lines in their migration corridor.
The Rusty Patched is the first bee to be listed as endangered in the US. Populations have declined as much as 87% from habitat loss, disease and pesticides. Climate threats include: warming and precipitation, early snow, late frost and drought. Bees and butterflies are important agricultural pollinators. In 2016, 40% of invertebrate pollinators (bees and butterflies) were listed as threatened with extinction.
Clownfish live in the shallow waters of coral reefs where they have a mutually beneficial relation with a few species of sea anemone. The anenome protects the Clownfish, and the fish's swimming aerates the water around the anenome. Clownfish are unable to move long distances, and rising ocean temperature and acidity is a threat to their coral reef habitats. Increased acidity also seems to impair their ability to navigate to their home anemones.
Since 1960, the average summer temperature in Glacier National Park has increased by around 1 °C and glaciers have declined by 35%. By counting Stoneflies, scientists can determine how quickly glaciers are melting and the temperature of streams. In a two year search begun in 2011, scientists found the Stonefly in only one of the six streams it had previously occupied and discovered that it had retreated to two different streams at higher altitudes. Satellite data confirm that the world’s glaciers are declining, affecting the availability of fresh water for humans, animals and plants, and contributing to sea level rise.
