American Pika

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

Beluga
Belugas live in Arctic and Sub-Arctic waters. Impacts from climate change include: an increase in ship traffic as sea ice declines, oil exploration and extraction, fisheries by-catch, and disruption of the food web. As Arctic waters warm and currents change, the Humpback (a competitor) and the Orca (a predator) may move north and stay longer. Some Beluga populations are also threatened by hunting, pollution and habitat loss.

Leatherback Sea Turtle
Climate change impacts the Leatherback in two main ways: an increase in the temperature of nesting sands causes a greater proportion of females to hatch, destabilizing future populations; and sea level rise and stronger, more frequent storms erode nesting beaches and wash away eggs and hatchlings. The Leatherback is also threatened from fisheries by-catch, egg collection, coastal development, pollution and ingestion of floating plastics.

Monarch Butterfly
The annual North American migration of the Monarch is listed as a "threatened phenomenon." Climate related threats include: drought, storms, changes in precipitation and dependence on temperature to trigger migration and reproduction. The Monarch feeds and lays eggs exclusively on milkweed plants, so it is also highly vulnerable to herbicides and habitat destruction.

Common Clownfish
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.
