Alaskan animals are used to surviving in very cold weather. Alaskan animals can survive temperatures colder than -34 fahrenheit. During summer, the temperature changes from -34˚F to 54˚F, but topsoil remains frozen throughout the whole year. The weather can alter the balance of the tundra, and that puts the wildlife in risky situations. It becomes difficult to find food and resources. Even though Alaska is a tough place to live, polar bears, red foxes, wood bison, and eskimo curlew manage to survive.
The polar bear lives across Norther Alaska and Canada. Polar bears like to frolic and jump from floe to floe. The major food source of polar bears is bearded seals. In 2008, the polar bear was classified as endangered. Various companies began to offer tours by boat in an effort to see polar bears before the polar bears potentially disappear.
The red fox and the Artic fox are fighting for the same resources. The red fox is invading the Artic foxes’ territory, and that causes a conflict between these two species. The red fox can weigh more than 15 pounds as an adult. It is really rare to see a red fox in the tundra, and you would be really fortunate if you did. The Artic fox changes its coat to match the seasons, and it weight more than 7 to 21 pounds as an adult.
The wood bison can grow to six feet tall and it can weigh more than 2,000 pounds although the bison in Alaska had gone extinct, the Alaska Wildlife Conservation Center re-introduced 130 bison from Canada in 2015. Now they live in Western Alaska.
The eskimo curlew is also on the endangered species list, although it might actually be extinct. In 1996, it was seen but not officially documented. The last official sighting was in 1962 in the south of Texas while it was migrating to Argentina. It was known to spend the summer in Alaska and the Canadian Northwest.
All these animals are in danger because of the changing temperature. Humans need to start taking responsibility for global warming because it causes wildlife to become extinct.
