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.
Polar bears are considered one of the cutest animals in the world and are adored by thousands of people. Not only are they adorable, but they are also going extinct because of the warming temperatures in the Arctic. But what mankind does not know is that warmer climate isn’t the only thing killing off these animals; it’s truly cannibalism. This surprising truth is revealed in a similar way in Rod Sterling's short story, “Monsters Are Due On Maple Street.” The story takes place in an ordinary neighborhood that is supposedly being attacked by aliens.
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
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
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.
This means that bears need to get food before winter hits. Getting food before winter is beneficial because bears can have food already when winter comes so they don't have to waste their time trying to find food that is already dispersal. bears need to stock up on food before winter comes because in the text it states"
As a man cautiously walks through the dense forests, he looks at his surroundings. He hears claws dragging through the dirt covered leaves. He then sees a dished shaped face pop out of the trees. Is it a Grizzly Bear or Black Bear? These creatures may look alike, but the difference between them could mean life or death.
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.
The amount of arctic sea ice is declining more than ever. Polar bears are being greatly affected by the decreases in sea ice. (Doc A) This is affecting their diet because without enough sea ice it has been very difficult for them to catch seals to eat. Also, their population is decreasing due to the longer periods between hunts.
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
