American Black Bear

Polar bears and penguins are usually found mostly in the arctic or cold areas of the earth. Sometimes it can get to as cold as - 29℃, with little protection the weather can be deadly. Polar bears and penguins have so many different adaptations and ways of protecting themselves from the weather and keeping warm by using convection, conduction and radiation. Some ways they keep warm by using the 3 heat loss methods are . . . Polar bears lose a lot of heat just through their tail and ears. Their…

In order for polar bears to preserve their species and live long healthy lives, and avoid stress, they must live in a stable environment with an appropriate consistent diet. Since Polar Bears have been recognized as an endangered species under the Endangered Species Act in 2008 by the U.S. Fish and Wildlife Service (The Alaska Zoo 2005), it is essential to use precaution to preserve them. Captive facilities like the Alaska Zoo possess the sufficient resources for the polar bears that will aid in…

at least one polar bear is tightly grasping onto a single slab of ice that barely supports its body weight of over two-thousand pounds. Due to increasing sea levels, the ice that the polar bear is lying on will evaporate in less than two months. Paddling to find land will lack success as miles of shark-infested waters and several other threats lie between it and a temporary Shangri-la. Its chances of survival are slim, but to lower this probability even further, the polar bear is consistently…

Bears bodies help them survive in their habitat and keep warm in the winter. “Bears have heavy bodies with long, thick fur, loose skin, and large, hairy heads.”I researched how bears bodies help them survive, along with how bears survive in the cold, frosted winter. First off, bears bodies help them survive. “Bears have heavy bodies” with “loose skin” and “large, hairy heads.” Bears have hefty paws and needle-sharp nails to dig up food for themselves or bugs, they can as well tear their prey…

under and overcoats that they shed once a year. Seals are protected from the cold by a thick layer of blubber combined with a tick fur coat. Another animal resistant to cold weather is the polar bear; this animal it has its protection from his thick fur and because of its large and heavy body. The polar bears are very good swimmers in cold water. Also, when they swim long distances they cover most of the distance floating on ice. It certainly helps to be big and…

Imagine a polar bear, sitting on the edge of the ice. He’s at the northernmost point of the earth, with family behind him. They are in sight, as the father bear makes his way across the slippery frozen wasteland. Suddenly, the ice fractures. The arctic animal floats away on an iceberg into nothingness, to never see his family ever again. Do you want this to happen to a hopeless, innocent animal? Well, it’s already happening which is why global warming is a serious issue and needs to be dealt…

Polar bears (Ursus maritimus) live throughout the ice-covered waters of the circumpolar Arctic, particularly in near shore annual ice over the continental shelf where biological productivity is highest. However, to a large degree under scenarios predicted by climate change models, these preferred sea ice habitats will be substantially altered. Spatial and temporal sea ice changes will lead to shifts in trophic interactions involving polar bears through reduced availability and abundance of their…

Topic: Not Too Late for Polar Bears Specific purpose: To inform the class about the Arctic is warming too. How will Polar Bears survive by 2050? Central idea: Without Polar Bears, other animals couldn’t survive. Polar Bears kill other animals so that smaller animals can eat to survive. Smaller animals do this by eating the leftover scraps from polar bears. Introduction: On August 1881 a naturalist by the name of John Muir sailing off the coast of Alaska discovered a large mammal. He said they…

Wilson, K. (2002). Bear snores on. Simon and Schuster. “One by one, a whole host of different animals and birds find their way out of the cold and into Bear's cave to warm up. But even after the tea has been brewed and the corn has been popped, Bear just snores on! See what happens when he finally wakes up and finds his cave full of uninvited guests -- all of them having a party without him!” (goodreads.com) After reading the book to the kids have them make a cave for the bear and his friends.…

They have a thick layer of fat under their skin, which is surprisingly black. They have a dense undercoat helping insulate heat. “Each hair shaft is pigment-free and transparent with a hollow core that scatters and reflects visible light, much like what happens with ice and snow”(1). Although their fur appears to be white, it is actually transparent. Insulating heat is key to surviving the artic temperatures. The bears are seen bathing in snow and water after a swim or meal, to maximize their…
