Bears Are Us Paul and Pete have been life-long friends who attended college together studying wildlife biology. After they graduated from college, they both took salaried positions within the U.S. Forest Service. During this time, they decided to dedicate their spare time to understanding and appreciating the protection of grizzly bears. Paul and Pete have formed a recognized partnership, by doing business under the fictitious name of “Bears Are Us”. Although they lack written documentation, the joint management of the organization involves collecting donations, conducting presentations, selling books and prints, writing articles, and actively promoting other events related to the protection and benefit of the grizzly bear.
Help with loosening the dirt when digging in the ground. The grizzlies also help with controlling populations of small animals. Pros and cons of grizzly bears. The first pro would be that they bring biodiversity among the large predators. They sometimes have a very little effect on
In the editorial by Ron Judd titled “Why returning grizzlies to the North Cascades is the right thing to do” found on the Seattle Times’ website, Mr. Rudd states his case for the reintroduction of Grizzly bears into the North Cascade Mountains of Washington State. He makes the argument that fatal interactions between hikers and bears are not a valid argument against reintroduction because the rarity of these encounters and the rarity of aggressive bears. He also cites some of his personal experiences encountering these animals and both his own and their reaction. Mr. Rudd uses this information to paint a picture that the bears are not as dangerous as commonly believed, using as an example the presence of grizzly bears in Yellowstone National Park which sees many more visitors than the North Cascades. Another point that Rudd discusses is his belief that bears are an important part of the wilderness experience, he shares his feelings after one of those encounters: “With senses heightened off the charts, it was as if I had stopped observing the natural world, and for the first time, stepped all the way into it.
Also bears are mammals since they give birth to live animals. Plus there exist to be various types of bears such as black bears, grizzly, panda, polar, and sun bear. Also a bear lives in caves, and trees. Conclusion Bears are a significant fragment of the earth since they keep the deer overpopulation from happening. Also, they eat most of the beetles that eat the
Grizzly bears are a dominant species in their niche. They are located in the north america deep into the forest. There favorite food is salmon. There ecosystem is filled with all sorts of other wildlife. Grizzly bears are also efficient in the ecosystem.
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
American Black Bears have claws about two inches shorter than the Grizzly Bear. In the wild, a Grizzly Bear’s color ranges from black to blonde similar to a Black Bear who are dark colors or white. Grizzly bears are usually no longer than 6.5 feet and live for about 28 years. American Black Bears are usually 4.5 feet long and on average live ten years, but can live up to 30 years old. Even though these animals have similar fur colors, the texture of them is totally different.
This essay will be discussing how bears prepare themselves for the hard times of their life and why. Once the winter months start to roll around food gets scarce and it is hard for them to eat so instead of staying awake and starve themselves, they hibernate. In order to prepare themselves for this difficult time of year, the bears must create a safe shelter, gain a few extra pounds, and drink almost three times the amount of water as usual. Black bears are located all throughout the United States and they all have different ways of preparation depending on their environment. (Reference.com)
As a consequence, these animals are now forced to spend more time on shore scavenging for food, often going without while awaiting new ice to form in the fall. There is also growing concern for polar bear cubs that are thought to be incapable of swimming the increasingly greater distances in open water between shrinking ice floes. As evidence, they offer the growing number of very young polar bear carcasses that they notice being washed up on shore. Many mother bears also appear to be dangerously thin and less able to fend for themselves and their young. This situation is quite noticeable among polar bears along the western shore of Hudson Bay, especially around the town of Churchill Manitoba, a location where polar bears traditionally spend the late months of fall foraging on shore awaiting the freeze-up, a freeze-up that now comes later each year.
Methods: To test my hypothesis, I will use an online random number generator to gather photos from different time frame distributed evenly between each hour (5 per hour and 90 photos total). 30 photos between 7am-1pm, 30 photos from 1pm-6pm, and 30 photos from 6pm-12am. The reason I will look at different timing is to see if the hypothesis is true at all time or just in some of the time frame. For each photo, I will count all the Seagulls and Bears found in order to see the relationship between the birds and the Grizzly bears. I will also try to see if they`re both are found at the same time and place.
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.
This issue that I have chosen is the impact of global warming on polar bears. A polar bear major/main threat is due to global warming is the loss of sea ice habitant. These polar bears are marine mammals, which mean they spend most of their time in the sea than on land. The polar bears make their living on the arctic ice. Global warming also has an impact on the population of polar bears (population size decreasing), the sea ice platforms are moving farther apart; which is making swimming conditions more dangerous for the polar bears, it is impacting on their hunting opportunities (fewer), and increased scarcity of food.
Apart from the sea ice, the polar bears have very few alternatives left when the ice melts and when their access to the ringed seal prey disappears with their habitat. The charismatic arctic hunters cannot adjust and sustain themselves on another food source. If the devastating process of climate change continues, there wouldn’t be a thin sheet of ice left for these extraordinary animals to survive
Climate change, specifically warmer temperatures, has extensively altered these habitats by reducing sea ice extent, thus affecting polar bears since they use it as a platform to travel, hunt, and rest. Changes in the timing of sea ice formation and break up limits the amount of time bears can feed off of seals during late and early summer, hence limiting the amount of fat they are able to store for later seasons. Lower rates of food intake and storage correlates to low reproductive rates, and since females do not have sufficient fat and mass required for successful parturition, they abstain from
The bold idea to establish grizzly surrogate mothers is one of the strategies proposed to counteract this problem and ensure a long lasting population. Grizzly bears are genetically similar to polar bears but are different because they have adapted to survive in warmer conditions. This is one of the main reasons they are still seen more often today. If the population of polar bears were to drop drastically, then we would be forced to look at the grizzly mothers as one of our only options. The transplant of polar bear embryos into grizzlies is all it would take to keep the declining population at a steady and safe
