Sun Bears Research Paper

The Polar bear lives in the artic and uses the area’s costal waters and ice sheets. They are well equipped to live in this environment because they have a thick coat which serves as an insulator. They mainly prey on seals but have also been known to consume dead whales. They can grow to be 7.25 to 8 feet tall and can weigh around 900 to 1,600 pounds. Polar bears are a keystone species, if their numbers decrease there is a possibility that the seal populations will increase which could be devastating for crustaceans and fish. They help keep populations in balance.

The melting sea ice is also affecting the polar bear's main prey, seals, forcing the bears to turn to alternate, less nutritious food sources. Once sea ice forms in the winter, seals use the ice to create dens to give birth to their pups. In these months, polar bears use sea ice as their hunting grounds to find seal dens. Now that Seasonal Ice is forming later and melting earlier (IPCC, 2013), seals have less time to build dens and give birth. Consequently, polar bears have less time to hunt their preferred prey of seal pups. They must spend more time on land hunting other animals of less nutritional value. Organizations like Sea World Parks have reported male polar bears occasionally eating newly-born polar bear cubs because they cannot find other food to eat. Lack of nutritional food leads to a reduced body size. Polar bears are becoming thinner and weaker from not eating enough (Rode, Amstrup, & Regehr 2010). They have to swim longer distances to find ice to hunt upon, causing many cubs to die because they are not yet strong enough. In the Hudson Bay, the average polar bear weight has decreased by 15% and the population has decreased by 20% (National Wildlife Federation). In the summer when there is no ice, polar bears in the Hudson Bay go onto land to fast until the ice reforms. Now that ice is

Grizzly Bears - they are large bears that inhabit North America. Many people hunt them.

The grizzly sheds the thick part of their coat during the summer. The coat also protects the grizzly bear from insects or any types of bugs. The grizzly bears have a very large home range that they will roam through. The grizzly bear also spend hours of the day walking around, but that is common for grizzly bears. The wear in the temperate rainforest is sunny and sometimes rainy. When the grizzly bear needs to move quickly through their habitat it can be done so at a speed of 30 miles per hour. The mating season for grizzly bears start in mid-May it continues until the middle of July. Grizzly bears can live in the wild up to 30years. They can also die at the age of 25. Grizzly bears can be found in woodlands, forests, alpine meadows and prairies. They prefer to be around streams or rivers. Grizzly bears are mainly solitary, except for mothers and their cubs. Grizzly are known to meet up at a river or a stream. Grizzly bears are also very strong swimmers. Grizzly bears use sound, movement, and smells to communicate with each other. Grizzly bears happen to groan and moan to get each others attention. Grizzly bears also rub their bodies on trees so they scratch their self. Throughout the summer grizzlies build up fat by eating as much

The Spirit Bear, or actually called the Kermode bear, lives in the Great Bear Rainforest in the Northwest area of the Canadian province British Columbia. Half way up the coast is where they live. “Scientifically, the white ones, along with their closest black relatives, belong to a subspecies of black bear.”(Smithsonian) The big white bear is probably around 300 lbs. It is cold where they live, and their fur definitely helps them keep warm. They hunt for things like salmon, and just eats it up. Right now, the some estimates say there are only around 100 of the specie left. They are very rare and definitely one of the rarest type of

Black bears are the smallest North American bears however; they are the largest land mammal in New Jersey. Black bears evolved in thick forest and live in mixed hardwood forests, dense swamps and forested wetlands. They naturally like to eat fresh leaves, berries, fruits, nuts, roots, insects, bird eggs and small mammals. Black bears are generally solitary animals, with the exception of a sow and her cubs. They tend to be crepuscular, meaning they are most active shortly before sunrise and again after sunset. Black bears are typically not aggressive and tend to be wary of humans.

and Canada offer, black bears can live in both coniferous and deciduous forests, as well as the open alpine habitats. Basically anywhere near a river or some water source, has plenty of trees, and are able to find food. Black bears usually forage alone, even as young cubs. They will stick together with their mother if there is an abundance of food in one are.

It was a Kermode bear. You aren’t allowed to hunt them, just allowed to see. 200 miles northwest of Orr, Minnesota a black, white bear was also found. When they found the bear genetics were never studied. To this day they still haven’t studied the black, white bear’s genetics. Then another Kermode bear was found in 2004 300 miles northwest of Beausejour near Cedar Lake, Manitoba. This cub was named Maskwa, also it also carried the same genetics that black, white bears have to this day.

The predicted droughts will likely have a large effect on the bears’ food sources. Droughts can warm river temperatures, negatively affecting fish (a lesser food source of bears) [5]. Droughts also lead to suppressed plant growth, as they don’t receive enough water to thrive [6]. The majority of bears’ food comes from plants and trees [3,4], meaning that they will have a harder time finding food. In addition, there is a significantly higher risk of forest fires during a drought, which destroy a lot of

Lifespan: Black bears can live up to 30 years in the wild but most only live around 10 years because of circumstances involving humans. Over 90% of young bear deaths are the results of gunshots, traps, vehicles and various other human interactions.

The Ursus Arctos otherwise known as the grizzly bear lives in North America around Northern Canada, Alaska, Wyoming, Montana, and Idaho. A grizzly bear lives in the wild and hunts for its food such as fish, deer, elk, or any other animal. They live inside of caves for protection from the weather, they will also live under trees or anything that will provide them shelter. I believe that grizzly’s have evolved into animals that can survive in many climates and environments.

This means that they eat nuts, berries, fruits, leaves, and roots and other animals from rodents to moose. For being 800 pounds and also being 5 to 8 feet they are fast animals running up to 30 miles and hour or sometimes 35 miles per hour. Grizzly bears once lived in much of Western North America and even the Great plains. When the europeans settled they killed many of these bears from both of these areas. Today the Grizzly bear population in the U.S. are safe because they are protected by law.

Polar bears are the top predator in the tundra biome. The polar bear mainly eats seals. Polar bears are the largest land carnivore on earth, their average weight is 990 for males, and 500 for females. Polar bears have white fur, but black skin. The black skin is used to absorb sunlight for warmth, while the white fur is used for camouflage.

Grizzly bears are a very unique type of bear. The bear has long sharp rounded claws. They also have large muscles in their back that help them dig. The bear has grizzled fur to help distinguish them from black bears. It is very important that we do everything to protect the Grizzly population.

Bear is a true carnivore, but if not prevented the black bear could be a huge problem to humans.
