Wild Bears In Alaska Research Paper

The trophy hunting of at-risk grizzly bears is a controversial topic in Canada. It is part of the Canadian cultural inheritance. Hunting grizzly bears are considered to be a legitimate recreational activity in some parts of Canada. They inhabit in the forest and near the costal line. The numbers of bear reached tens of thousands before, but because they are fierce and threatening human beings, they are being hunted and killed. Also, the low mortality rate of grizzly means low population, but they play a critical role as a predator in the ecosystem. The problem is over-hunting and industrialization will cause extinction of this rare species, and lead to disharmony between the government and First Nations. I mainly support the ban of grizzly

The Grizzly bears population has grown from about 200 in 1975 to approximately 600-1200 in the 18 million acers of the Greater Yellowstone ecosystem. (Yellowstone)

The Polar Bear (Ursus maritimus) is a bear native largely within the Arctic Circle encircling the Arctic Ocean, its surrounding seas and land masses. Although it is closely related to the Brown Bear, it has evolved to occupy a narrower ecological forte, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet. Though there are many theories surrounding evolution, the two stand outstanding hypotheses applying to the modification from Brown Bear to Polar Bear are Lamarck’s theory of Use and Disuse, and Darwin’s theory of Natural Selection. The intention of this paper is to compare these thesis and determine the most appropriate in

As a result, humans are slowly destroying the bear's ability to reproduce, and function in a normal way. By removing chemicals such as mercury, DDT, PCBs and lindane to name a few from our waste it is possible that the world may be able to retain our population of arctic polar bears, and preserve the beautiful creature for generations to come. Alternatively, people should use this as a warning of things to come if they continue to be so irresponsible about their waste. The implications to other ecosystems could be sufficiently more devastating than what is being witnessed in the arctic, and it is humanity's responsibility to take action now before it is too

In response the declining population of the polar bears, the United States Fish and Wildlife Service is drafting up a conservation management plan to save the white furry friends. The draft of the conservation effort can be found here (http://www.fws.gov/alaska/PDFs/PBRT%20Recovery%20Plan%20Book.pdf).

With their habitat being wiped away, their own food sources being toxic, to the very environment harboring chemicals; they are truly struggling to survive. Furthermore, hunting, although not a threat on its own, poses a great deal of risk to this species because of the threats outlined previously. If it were not for the disadvantageous situation the species currently face, it would likely not pose a threat at all. The aim of this paper is to provide an overview of the threats faced by polar bears in Canada such as global warming, bioaccumulation of mercury, biomagnification of polychlorinated biphenyls and hunting. Furthermore, hunting quotas placed on northern Indigenous populations will be analyzed as a conservation method that is helping to reduce further strain on the existing populations of this Canadian

Many people may not know that Canada is home to one of the largest subspecies of polar bears called Ursus maritimus. These polar bears are notorious for being a nuisance for the people of Churchill, Man. Every year, hundreds of polar bears gather on the western shore of Hudson Bay to hunt for seals once the ice freezes. There is one very large issue about this; the polar bears have not eaten in months due to hibernation. This makes the polar bears very desperate for food. The polar bears often invade towns and become aggressive to the townspeople. An important question arises: what is the government doing about it?

Polar Bears in 2008 was listed by the US government on the list of endangered species. Thus, they became the first species recognized as endangered due to global warming.

Regardless of the studies continuously being done on the polar bear and brown grizzly bear lineage, the polar bear is listed as “vulnerable” which is one level below “endangered” on the International Union for Conservation of Nature List. This is due to the warming climate, loss of sea ice, threats of hunting, shipping, and pollution (Hailer, Verena, and Bjorn, 2012).

Bears are usually lonely and peaceful, but if you enter a bear's "personal space" the bear may become aggressive. All bears reach an age of 30 years or more. The Brown bear's scientific name is Ursus Arctos. The "Kodiak bears are the largest subspecies in the world. " The Kodiak bears are large, but the largest bears are the Polar bears.

Polar bears are one of the most endangered species in the IUCN states this is due to Global warming which most of us are still ignorant about, It has a climatic impact on the Arctic by the rising temperature which results in melting the ice glacier and these glaciers are the homes of polar bears that have been disappearing and shrinking making it

Using the film and their theories, Bears shows the possible outcomes of Climate Change in Alaska and on the bears, and how they affect the other. Michael Carey emphasizes the idea that people once thought of Alaska as an “unchanging, eternal face,” but now consider it the “center of national and international climate change discussion.” Monika P. Calef treated Alaska’s Climate Change and what Bears portrays from a vegetation perspective, claiming that with the decrease of tundra areas due to Climate Change, forested areas were growing due to Alaska’s warmer temperatures, as well as causing other habitats to change and give other resources. Lowell H. Suring with his ideas of human impact related that other environmental factors influenced the “availability of important foods” for bears. Each of these articles relates to how Bears change what Alaska means to us as an unchangeable wilderness to a wilderness that is changing due to Climate Change. In addition, Bears means to us that Climate Change will not only change the life of the Alaskan bears, but it will change the lives of those who are also in our environment and any others in the future that come after

The polar bear (Ursus maritimus) is the biggest terrestrial mammal in the Arctic. He is also considered as an animal with a circumpolar or broad distribution in polar regions. The conservation status of bear remains problematic, according to the global warming that is happening now. If further managements are not implanted, polar bear population`s will disappear in the future. The polar bears live in the Arctic, an ocean surrounded by land. The Arctic has a very low species diversity and polar bears the first animal into the food chain. Also, the Arctic has cold winters which are not suitable for some aquatic species. With global warming and interglacial period, the ice and snow began to recede about 20.000 years ago. The rate of ice loss has

As reported in KRQE, http://krqe.com/2015/07/05/study-polar-bears-could-feel-global-warmings-sting-by-2025/ despite being the first species to be listed under threat under the Endangered Species Act for global warming, the plight of the Arctic polar bears is ongoing. Researchers fear that we'll see how bad we've hurt the Arctic polar bear as early as a decade, or 2025.

The carnivorous Grizzly bear (Ursus arctos L.) is a North American subspecies of the brown bear and is nowadays the most widely distributed ursid. Nielsen et al (2006), likens the Grizzly bears as keystone species suitable for discovering conservation habitat modelling from a survival and occupancy framework. During the past century their population have declined noticeably throughout much of North America, mainly due to susceptibility from low density, high trophic level, low reproductive rates and late maturation. Also, the increased illegal human access causes the mortality of most of the grizzly bears. Their demographies has also been changed; the brown bear in the lower 48 states has been reduced to <1% of its original area. The estimated population size has fallen from 100,000 in the early 19th century to <1000 in 1986 (Waits et al 1998).
