Rivera, Ma. Ione Skye Niches and Adaptations Part I: Animal #1 BLACK BEARS American Black Bears are forest dwellers and are usually found in mixed forest areas and also places that can be as high as 10,000 feet in elevation. Their habitat is mainly in an understory surrounded with lots of fruits, nuts, and berries.
Earth’s climate has been changing over the last few decades, with the global temperatures rising at a high rate (Corell, 2006). Some of these climate changes are due to natural causes, although the strength at which temperatures are rising indicates human influences, such as increased carbon dioxide emission, as well as other greenhouse gases. Climate change particularly affects the Arctic region, where warmer temperatures are causing decrease in sea ice extent and thickness, permafrost thawing, coastal erosion, changes in ice sheets and shelves, and consequently, changes in the distribution and reproduction rates of Arctic species (Corell, 2006).
Blubber If an animal habitat is located in a cold, frosty area, such as the Arctic Circle, bearing with the weather could be a challenge. Many warm-blooded animals, such as whales and seals, rely on blubber to keep their body temperatures up. Whales, for example, are constantly swimming. They could not survive in the frigid water without their blubber protecting and keeping them warm.
Also known as the polar rabbit, the arctic hare is a species of hare which has adapted to survive in polar and mountainous habitats. These hares have thick fur and usually burrow into the ground or under snow to keep warm and sleep. Arctic hares have shorter ears than rabbits, and they thrive in extreme cold. Arctic hares can run up to 60 kilometres per hour. This species of hare is prey to many predators, including ermine, hawks, wolves, falcons, humans, and mostly, the Arctic fox.
One of the main reasons polar bears are going extinct is because they aren’t getting the right amount of food they need to survive. Seals, the main food source for the polar bears, are animals that depend largely on the algae that grows on the ice of the Arctic. With the ice content slowly depleting, there isn’t enough seals to sustain the polar bear population. One of the
The United States of America abounds with beautiful scenery, amazing natural resources, and fascinating animals. Each state can boast of its unique natural resources. The state of Alaska provides an abundant habitat for numerous species of mammals, fish, and birds.
There are 3 types of polar bears: ones with thick coats, ones with thin coats and ones with medium coats. It is fall, soon to be winter. The temperatures are dropping rapidly and the bears must be kept warm, or they will freeze to death. Many of the bears have had 2 cubs each but due to the extreme temperatures, many mothers only have one cub left. a. What bear will natural selection select AGAINST?
Grizzly bears are a dominant species in their niche. They are located in the north america deep into the forest. There favorite food is salmon. There ecosystem is filled with all sorts of other wildlife. Grizzly bears are also efficient in the ecosystem.
They use the ice to rest on while hunting for seals, but since there is less ice it’s causing the polar bears to drown from exhaustion. Walruses can eat up to 200 pounds of clams each day. Clams are usually found near the continental shelf but with ice caps melting it is getting harder for walruses to find
