Isle Royal is an island surrounded by the cool Lake Superior. Wolf and Moose are the two largest species on the island, and the wolf and moose interaction is the longest running large mammal predator-prey study on earth (USNPS, 2014). The two populations were once said to exhibit some kind of “balance of nature,” now that is not believed to be the case (Vucetich, 2012).
Isle Royal is located fifty-six miles north of Michigan’s Keweenaw Peninsula. It is the largest wilderness area in Michigan (USNPS, 2014). The island is surrounded by Lake Superior, which creates a cooler temperature. This results in arctic plant species growth on the island. There are only eighteen mammal species present on the island because most mammals cannot make the trip across the frozen great lake (USNPS, 2014). The need for an ice bridge is not the only environmental factor that is stopping the migration of animals; there is also the severe cold, and also wind and fog (Vucetich, 2012). Some species such as caribou and coyote have found the island to be too intense and have gone extinct (Vucetich, 2012). Due to the harsh weather and isolation of the island, humans have never regularly lived on the island (Vucetich, 2012). Some of species that are present such as the red squirrel are becoming their own subspecies due to its separation from the mainland (USNPS, 2014). The isolation of Isle Royal is what makes it a great place to conduct research, it has very low human interaction and the species that are on the island will have been and continue to be isolated from the mainland.
The gray wolf, Canis lupus, on Isle Royal is a small ever fluctuating population. On the endangered species list since 1978, the gray wolf has recently been taken off the endangere...

The Bull Moose Essay

- The Bull Moose "The Bull Moose" is a poem by one of the great Canadian poets, Alden Nowlan. It is a finely crafted poem by a very talented poet. It reminds us how far away from Nature the lives of ordinary men and women have strayed. This is something common to all of us who live so much our lives in buildings and who so rarely experience Nature in its raw form. Nowlan creates powerful layers of images, and contrasts them in a way to make us feel just how damaging to our minds and souls this separation from Nature has been....   [tags: Moose]

Analysis of The Moose Essay

- Analysis of The Moose Elizabeth Bishop's "The Moose" is a narrative poem of 168 lines. Its twenty-eight six-line stanzas are not rigidly structured. Lines vary in length from four to eight syllables, but those of five or six syllables predominate. The pattern of stresses is lax enough almost to blur the distinction between verse and prose; the rhythm is that of a low-keyed speaking voice hovering over the descriptive details. The eyewitness account is meticulous and restrained. The poem concerns a bus traveling to Boston through the landscape and towns of New Brunswick....   [tags: Elizabeth Bishop The Moose Essays]

Analysis of The Bull Moose Essay

- Analysis of The Bull Moose "The Bull Moose" by Alden Nowlan is a finely crafted poem which reminds us of how far man has strayed from Nature. Through a carefully constructed series of contrasted images, Nowlan laments, in true Romantic fashion, man's separation from Nature. The strength of the old moose is impressive. On his death march, he nonetheless comes "lurching" and "stumbling" in ponderous and powerful strides to "the pole-fenced pasture'- the edge of civilization. A crowd quickly gathers, a crowd of men and women, old and young - all notable for their insensitivity and lack of respect....   [tags: Bull Moose Essays]

The Power of The Sea-Wolf Essay

- The Power of The Sea-Wolf Jack London’s novel, The Sea-Wolf, has many different interpretations. The story can be read as a combination of the naturalistic novel and the sentimental romance, both very popular around the turn of the century. London also brings into play literary naturalism, in which human beings are characterized as just another species in nature, subject to all of Her cosmic forces. The Sea-Wolf fits almost perfectly the archetypal pattern of an initiation story. Depth and interest are added to The Sea-Wolf by successfully integrating these three elements -- the combination of two popular genres, literary naturalism, and the initiation story....   [tags: Sea-Wolf Essays]

Essay about The Wolf

- The Wolf Destiny, perhaps from the very beginning, claimed the wolf as a symbol. Has any other animal stirred human passions the way the wolf has. Its haunting howl, its incredible stamina, its brilliant eyes, and its superiority as a predator all have been reviled as nefarious, and even demonic, traits. Ironically, these same characteristics have also been revered as belonging to a majestic, and sometimes spiritual, creature - a symbol of the magnificent, untamed wilderness. In truth, the wolf is neither evil nor exceptionally good - neither demon nor god....   [tags: essays research papers]

Wolf Reintroductions Essay

- Wolves were once the most widely distributed mammal on the planet. With their exceptional ability to adapt, wolves occupied almost every habitat except tropical jungles. But with the arrival of humans, wolves numbers diminished. Systematic eradication programs were aimed at top predators; this, along with over-hunting of prey populations and habitat loss due to population encroachment, wolves were eliminated from most of the contiguous United States by the 1940s. In 1973 wolves were finally put under the protection by the Endangered Species Act, and just recently wolf populations are increasing due to wolf recovery and reintroduction projects....   [tags: Environmental, Endangered Species, Yellowstone]
