Black Bears Research Paper

BEARS Did you realize that a bear can almost weigh as much as a car and can be strong enough to break parts off of a variety of items? Although they’re shy and easily frightened, you should maintain a distance. How big is a bear?

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.

It could even be just another type of salmon, like Sockeye Salmon, Pink Salmon, or Chinook

Yellowstone has 61 different mammals spread around the park including moose, elk, badgers, otters, and many others. Yellowstone is the ultimate Bear Country with over 500 grizzly bears plus an estimate of 600 black bears. Bison are another huge wildlife attraction in Yellowstone with anywhere from 2,300 to 5,500 depending on the season. In January 2016, the amount of wolves recorded was 98 wolves living in 10 different packs. Now, there are at least 13 different packs spread over the

Ironically, most black bears are not black, but instead are mostly brown, blond, and sometimes reddish brown. Average adult males weight about 115 kilograms and females about 70 kilograms, thought the largest recorded black bear weighed 312 kilogams. Their diet mainly consists of grasses and berries, and acorns during the fall. Black bears consume about 20,000 calories per day, which is equivalent to a person eating 40 McDonald’s Big Mac sandwiches. A fun fact about Yosemite black bears is that their diet has drastically changed because they have become accustomed to eating human food.

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).

Kermode bears are important for many reasons. The idea of the Kermode bear started with Frances Kermode of the royal British army the bear was named after him because many people thought he was very important. Sometimes these bears can help states attract tourist which helps the state raise money to save the bear’s habitats and the bears themselves from being endangered. These bears are important to people in so many different ways like the bears help hunters in hunting season, they also help give people the meat and bones they need they need to survive and to help make a profit (Local Distilleries’ Fight for Spirit Bears). The Kermode bears are also called the spirit bear because of their white ghostly look which makes them important to some

While researching if we should reintroduce grizzly bears into the local San Bernardino and Los Angeles Mountains, I have came to a decision that grizzly bears should be reintroduced. Grizzly bears become extinct in a matter of 75 years. Wikipedia says, "Less than 75 years after the discovery of gold in 1848, almost every grizzly bear in California had been tracked down and killed...grizzlies were never seen again in California." Now, only 1,800 grizzlies are left in the United States. Like what happened in Yellowstone with the wolves, reintroducing grizzly bears could have great effects on the ecosystem. First, according to defenders.org, “Grizzly bears are found many different habitats, from dense forests to subalpine meadows, open plains and arctic tundra.” And according to Western Wildlife.org, “Grizzly bears are most often found on upper elevation slopes.” Both these quotes show that grizzly bears can be supported well in the local San Bernardino and Los Angeles Mountains. In addition, grizzly bears already lived in Los Angeles, and then, they were hunted to extinctions. Evidently, grizzly bears can live in California. Second, the grizzly bear diet consists of mainly berries, so they play a huge role in dispersing seeds.

Attention Getter] Did you know that according to the National Park Service, in the mid 1970s the Greater Yellowstone region only inhabited about 136 grizzly bears (United States)? A. The Federal Government quickly protected them under the Endangered Species Act, and that is still in force today.

Alaska Alaska is known for its great lakes and rivers. The main advantage about Alaska is that majority of the fishing grounds are in the proximity of urban areas such as Kenai Peninsula and Fairmont. Some of the fish you could catch here include; trout, landlocked salmon, pike, burbot, grayling and the rare sheefish which is found towards the state’s interior Utah The most notable place that everybody wants to visit in Utah is the strawberry reservoir. Anglers here enjoy the predominant species known as rainbow trout.

The gray wolf 's expressive behavior is more complex than that of the coyote and golden jackal, as necessitated by its group living and hunting habits. While less gregarious canids generally possess simple repertoires of visual signals, wolves have more varied signals which subtly inter grade in intensity.[12][13] When neutral, the legs are not stiffened, the tail hangs down loosely, the face is smooth, the lips untensed, and the ears point in no particular direction.[135] Postural communication in wolves consists of a variety of facial expressions, tail positions and piloerection.[120] Aggressive, or self-assertive wolves are characterized by their slow and deliberate movements, high body posture and raised hackles, while submissive ones carry their bodies low, sleeken their fur and lower their ears and tail.[136] When a breeding male encounters a subordinate family member, it may stare at it, standing erect and still with the tails horizontal to its spine.[137] Two forms of submissive behavior are recognized: passive and active. Passive submission usually occurs as a reaction to the approach of a dominant animal, and consists of the submissive wolf lying partly on its back and allowing the dominant wolf to sniff its anogenital area. Active submission occurs often as a form of greeting, and involves the submissive wolf approaching another in a low posture, and licking the other wolf 's face.[138] When wolves are together, they commonly indulge in behaviors such as nose pushing, jaw wrestling, cheek rubbing and facial

In Yellowstone there are only thirteen wolf packs (©AllTrip). Wolves cover a small portion of Yellowstone, and there are only around 400 in Yellowstone. Wolves predominantly feed on hoofed animals such as elk and deer. Wolves range in size from twenty-six to thirty-six inches tall and four to six feet long. Male wolves can weigh up to 130 pounds and females up to 110 pounds. The female wolves give birth to an average of five pups each spring. The main cause of wolf death within the park is other wolves. Wolves typically live eleven years if they make Yellowstone their home (Nat'l Park Service U.S Dept. of the Interior). The wolf’s primary food source, the elk, are some of the largest animal populations in Yellowstone.

The grizzly bears adapt to their environment by hunting down their own food. They hunt down carcasses of caribou, moose calves, walruses, ground squirrels, and salmon as well

A few bears, however, are enjoying independent activity-strumming a guitar and printing letters. However, all of the bears wear a smile and seem generally happy in what they are

Bears with thicker coats have a higher survival rate A population will change over time. Survial rate of bears with thicker coats rises, population of bears with thin coats will gradually decrease 3. In ostriches, there are 2 types: ones that run fast and those that run slowly.
