Of course they have similarities but they also have their differences. First off lets start with Polar Bears in Alaska. Polar bears have…

Polar Bear numbers have been decreasing and will continue from 2001 to 2010 there was a drop of about 40% in their population. In the wild there is suspected to be roughly 25,000 left. This can be explained by climate change. The increase of temperature there is a decrease in their habitat size and has been causing some strange behaviors in the polar bears. Polar bears have been observed saving food for later by burying it in the snow. The main food source for polar bears are seals, they have…

even if we say it is not. There is nowhere for the polar bear to go to because all of the ice is melted around him. This is a powerful photograph proving to people all around the world that it is happening. The sad part is, it only works on a small amount of people.

It is showing that the polar bear has nowhere to go. The photographer used a…

Topic: Not Too Late for Polar Bears Specific purpose: To inform the class about the Arctic is warming too. How will Polar Bears survive by 2050? Central idea: Without Polar Bears, other animals couldn’t survive. Polar Bears kill other animals so that smaller animals can eat to survive. Smaller animals do this by eating the leftover scraps from polar bears. Introduction: On August 1881 a naturalist by the name of John Muir sailing off the coast of Alaska discovered a large mammal. He said they…

Their frequently seen along or near coasts. The most important habitats for polar bears are the edges of pack ice, where…

Polar bears (Ursus maritimus) live throughout the ice-covered waters of the circumpolar Arctic, particularly in near shore annual ice over the continental shelf where biological productivity is highest. However, to a large degree under scenarios predicted by climate change models, these preferred sea ice habitats will be substantially altered. Spatial and temporal sea ice changes will lead to shifts in trophic interactions involving polar bears through reduced availability and abundance of their…

The polar bear (Ursus maritimus) are endangered due to accelerated climate warming, which is affecting sea ice thickness which polar bears rely on for finding food and mates (Elvin 2014). An approach to help support polar bear subpopulations is the Large Marine Ecosystem (LME) methodology. This method is used for assessing, monitoring, and managing ecosystems as well as taking into account of human activities; fishing, pollution, ecosystem health, etc (Elvin 2014). There are seventeen arctic…

starting to expand from cocoa bears, the polar bear's progenitors experienced a progression of developmental changes keeping in mind the end goal to make due in the Arctic. The bears adjusted to an existence of chasing seals and surviving amazing icy. A standout amongst the most amazing adjustments was the capacity to flourish with a fat-rich eating regimen without evident heart harm. Protection. Two layers of hide and a thick layer of muscle to fat quotients give polar bears such fantastic…
