Megafauna of North America

migrated out of Africa in waves successively increasingly, crossing over to Eurasia before migrating into North America. The residing megafauna in North America would face Paleo-Indians. The genesis of the extinction of megafauna have has been hypothesized to credit to the introduction of modern humans. The sudden introduction of a hunting and big-game predator into regions with megafauna led to the overkill of large faunas. The overkill hypothesis alludes to the fact that extinction of large fauna

food (and garbage). They lack the massive shoulder hump of muscle that characterizes the grizzly Bear. Black bears in Canada can be black, brown or white-ish in colour. They are not endangered and estimated put their numbers at around 600,000 in North America. The white Spirit bear, or Kermode bear, is actually a black bear and can not mate with the grizzly or polar

Black bears typically live in either coniferous or deciduous forests. For their food, black bears also like to live near rivers with lots of plants and animals. These habitats range all over North America, including Alaska and North Mexico (American Black Bears, 2015). Black Bears can adapt to their habitats, especially when they are in hot or cold climates. In the different climates, like the hot of Mexico, or the cold of Alaska, their fur coat or color may

The grizzly bear is one of many species of bear that inhabits the earth. Like many other species of bears the grizzly bear is a pure force of nature, weighing up to 800 pounds and standing over 9 feet on their hind legs. The grizzly bear is one of the biggest species of bear in the world coming second only to polar bear. From a taxonomic standpoint Black bears belong to the domain eukarya The domain that contains all organisms who have membrane-bound organelle's. Grizzly bears fall into the kingdom

The Mexican gray wolf is a large prey that, in the past, preyed on livestock which contributed to their near extinction by humans. However, the decline in the Mexican wolf lead to an overabundance in plant life which had a direct effect on other wildlife. There are many challenges involved with re-introducing wolves to other stakeholders such as to academics, mangers, ranchers, or landowners. It is not as simple as taking the Mexican wolf from where they are now and placing them in different areas

The Mexican gray wolf is a large predator that, in the past, preyed on livestock, which led to their near extinction by humans because they were tired of the wolves eating their livestock, they were a danger to people, and there were land use conflicts. However, the decline in the Mexican wolf lead to an overabundance of plant life which had a direct effect on other wildlife. There are many challenges involved with re-introducing wolves to other stakeholders such as to academics, mangers, ranchers

In Bears, a Disneynature documentary film, directors Alastair Fothergill and Keith Scholey filmed two Alaskan brown bear cubs with their Mother, in the coastal mountain regions of Alaska. This documentary chronicles the first year of life of the cubs Amber and Scout with their mother Sky. While facing a constant struggle in providing for and teaching her cubs how to survive in the Alaskan wild, she must also strive to protect her cubs against the changing landscape and climate, other rival male

Natural History in New York City we can get a first-hand look at some of the massive creatures like the wooly mammoth that used to roam our planet some 11,000 years ago. And after viewing the skeletons of such extraordinary creatures known as the megafauna we may ponder as to what event transpired to eliminate so many species. What we do know is the late Pleistocene era marked a time of fluctuating climate that coincided with the migration of people into the New World. During this period mammals such

woolly mammoth (Mammuthus primigenus) roamed the Earth. The woolly mammoth is one of the most studied megafauna of the Pleistocene epoch, which spanned from 2.6 million to 11,700 years ago. Most populations of it died out around 10,000 years ago [4], although a small population survived until around 3.7 thousand years ago on Wrangel Island [6]. The woolly mammoth was one of the many now-extinct megafauna that existed during the Pleistocene. Others include the cave lion (Panthera spelaea) and the ground
