Kermode bears, a certain type of black bear, are white because they have a special a recessive gene called MCR11. MCR1 is a recessive gene that causes the pigmation in the bears skin to turn white. Even though they are white they are not albino (Kermode.) MCR1 is caused by ultraviolet light (No, Name.) Even though the bears are white it doesn’t mean the parents have to be (Bec.) They just have to pick up the gene. Kermode bears are most commonly found on Princess Royal Island in south east Alaska. 1/3 of the bears there are white…
Polar bears are extreamly well adapted tohunt their prey under water. Keeping warm is no problem for polar bears infact sometimes polar bears have to lay flat on their stomachs on the ice just to cool of. Polar bears have the thickest fur of any bear species. Their fur has two layers. The first layer, the under coat, is the closest to their body it consists of thick, plush, hair that retains heat. The next layer, the outer layer, is a layer made of "guard hairs" and are not actually hair at all they are hollow tubes. the tubes trap air for insulation andalso reflect a visible wavelengths of light in their hollow air space, which combine to make the fur whiteeven though it is in fact colorless. The white coloring provides camoflauge for the bears allowing them to blend in with there white snowy surroundings. Under their fur polar bears have black skin that absorb the sunlight and under that they have a 4-inch layer of blubber. This blubber keeps polar bears warm in the cold water. Polar bears have fur at he bottom of their feet providing extra warmth and traction to the ice. they are adapted to swim 60 miles without a pause to rest. They have have the ability to reduce their metabolic rate when the food is scarce and again when it's…
Black widows are found in hot countries thought the world, including the United States, southern Europe and Asia, Australia, Africa and much of South America. They may be found in dark, dry shelters such as barns, garages, basements, outdoor toilets,…

For their summer range, they resident across North America from northern Alaska and Canada through Mexico and Nicaragua and also in South America to Tierra del Fuego. They are found in dense woodlands of hard woods and conifers, along cliffs and rocky canyons, desert canyons, and in forest openings. They can even be found in wooded city parks, in caves, or on the ground. They prefer open areas to dense woodlands. The owls that live in the far north move southward in fall or winter.…
For the first scenario - if you see a bear in the wild, here are some tips to follow. These tips are the same for both black bears and grizzly bears.…
Bear attacks are rare, however, in bear-country areas where humans and bears coexist such as British Columbia (BC), the encounters are nearly inevitable. This study looks at newspaper articles on grizzly and black bear attacks on humans in BC and analyses an spatial or temporal trends from 2000-2016. The data showed that grizzlies had a higher attack rate of 18 attacks/10,000 individuals than black bears with 1.9 attacks. 10,000 individuals. Females with cubs also showed to have the highest frequency in attacks within the last 16 years. The locations of these attacks were quite variable with minimal patterns, however, generally, grizzly bear attacks occurred in the backcountry while black bear attacks ensued more in the front country with greater…
For a long time researchers have been trying to retrieve data on Grizzly bear diets. It is clear that all Grizzly bears have different habitats, food sources, and outside pressures such as human development. Although this is true Grizzly bears have been seen to commonly have the same diets over the course of seasonal shifts. For example, Grizzly bear diet and use of seasonally abundant, nutrient-rich food sources has been well documented throughout their range in North America. A wide diversity of foods is consumed, reflecting the species' omnivorous and generalist nature. Food-habit relations are therefore often locally variable, making extrapolations from other populations difficult. Even within a population, annual and seasonal variations in food productivity can alter…
The purpose of this memo is to explain the causes of extinction within the Red wolf population and the Black bear population. The topics chosen explain how this issue came about, what factors created, and provided some solutions on how to prevent it and keep these endangered species’ population thriving. There were several ways the black bear and red wolf came to the brink of extinction and these article provide multiple solutions to sustain and endangered species.…
Snow wolves have white fur and hunt in packs like regular wolves, they eat other species and are mammals, snow wolves are one of the most aggressive species and are smart, and takes care of their pups good too. Snow wolves survive in the tundra by using their white fur to blend in with the snow and hide from enemies, and fights in packs also eats smaller animals such as, snow bunnies and snow foxes. Polar bears are very big mammals and probably the king of the tundra leaving nothing in it's path, it has white fur, and it's very protective withs its cub. Polar bears eat other species smaller than them and the women polar bears eat fish and sometimes they take and feed fish while the fathers hunt with the other polar bears and also the polar bears use their white fur as camouflage they use their big and very fat stomachs to hold food while they hibernate during the summer. Snowy owls are active during the morning especially summertime and uses it's white fur to hide from dangers. Snowy owls use it's white to camouflage and eats insects to have energy. Snow leopards are endangered species and are large. Snow leopards usually run away from it's…
Harbor seals are found across the Northern Hemisphere in both the Atlantic and Pacific Oceans. In the northeast Pacific, they range from Alaska to Baja California, in Mexico. They live near-shore coastal waters and frequent sandy beaches, mudflats, bays, and estuaries. Some harbor seals even live in certain areas of Europe such as Finland.…
The most recent change was the molar teeth. With this change the polar bear now has forty-two teeth that are much longer and larger than the regular brown bear which have flat rounded teeth. The interbreeding of grizzle bears and polar bears has created a new type of bear. Polar bears and grizzly bears are breading at an increased frequency due to global warming, which is slowly forcing the polar bears out their natural environment. This cross breading has been increasing as more brown bears have been spotted in polar bear territory and parts of Canada, the traits of this new hybrid bear consist of long dirty white fur, long claws, wider teeth, and a slightly larger head. In addition, this new hybrid demonstrates more similar behavior to polar bears than grizzle…
Black bears are the only specie of bear that live in New England. (Whittle) Normally humans and black bears are able to coexist peacefully, however, the population of black bears in New England is growing–and it’s causing problems for the locals. In fact, there are currently around 36,000 bears in Maine, 6,000 more than there were five years ago. (Whittle) While some states are calling for hunters to increase the number of bears they kill during hunting season, some people are saying this method of population control is inhumane. Instead, they suggest trap and release methods be used in order to relocate bears to areas away from humans. There are different types of traps used to capture bears, however, most of them are dangerous and possibly…
The Great Bear Rain Forest consists of 64, 000 square kilometres of pure nature, in the coast of British Columbia. It is one of the rarest forest ecosystems on the plants, where trees grow to be over 1000 years old and partakes in being a home to a healthy population of grizzly bears and black bears rare white “Spirit” bears and wild salmon. In the Great Bear Rainforest the towering trees, fjords, islands, mountain slopes and estuaries support a rich diversity of plants and wildlife. Bears, wolves, mountain goats, Sitka deer, salmon and six million migratory birds are found here.…
Jennifer Churchill, a Wildlife Manager with Colorado Parks & Wildlife, says there are a lot of neighborhoods now sitting in the middle of bear country. “As Colorado grows we find people living in bear habitat, “Unfortunately a lot of folks don’t want to call us and tell us they’re having activity because they’re concerned we will come out and remove the bear. That’s not our preferred way of managing the animals.” said Churchill. Since 1960, 54 people have been injured and three more have died from bear encounters in Colorado. Bears make their way into the suburbs through corridors of creeks, rivers and drainage systems from the High Country. Other bears are living in their natural habitat among homes in certain towns, like Aspen. Wildlife officials recommend not screaming during a bear encounter. Instead, they recommend that you make yourself look big, back up slowly and give the animal a place to exit. Generally the bears want to get away from people. There are ways to deter bears from coming near your home or campsite. Install motion detector lights, be noisy or play a radio and use scent deterrents like bleach or ammonia fumes in or near your trash. If camping, Wildlife officials recommend that if you do anything with food do it two hundred feet…
