In this research paper, I will address the changes that occurred within the ecosystem of Yellowstone National Park since the reintroduction of the grey wolves. The paper will consist of four sections; the first section will include the history behind the extirpation and subsequent reintroduction of the gray wolf in Northern America. The second section will explore the political controversy that surrounds the reintroduction of the gray wolf in Yellowstone. The third section will contain discuss the gray wolf and its impact on the ecosystem of Yellowstone. I will conclude my essay by explaining how the gray wolves act as climate change buffers in Yellowstone amidst global warming. The history behind the extirpation of the grey wolf in the United States dates back to the very first European settlers that colonized eastern North America in the late 16th century. The killing of gray wolves was done primarily out of fear in an attempt to protect livestock, and, in some cases, to protect human life within the colonies. As more settlers expanded West, the practice of killing wolves was considerably increased to protect livestock that included cows, pigs, and chickens. As waves of European settlers expanded westward, they began to deplete the deer, moose, and elk populations. The gray wolves food source continual depletion gave rise to wolf populations actively targeting the settler’s livestock, causing great financial loss. The fiscal loss of livestock became such an issue to wealthy ranchers and settlers that they began to offer cash rewards for wolf pelts. This practice gave birth to a lucrative cottage industry of professional hunters and trappers. As the wolves began to move further West, and into Wyoming, they began to diminish the elk and moose population. To respond to this threat, Congress approved funding in 1914, to eliminate the native gray wolves from
Gray Wolf Optimization Gray wolf optimization is presented in the following subsections based on the work in [13]. 1) Inspiration: Grey wolves are considered as apex predators, meaning that they are at the top of the food chain. Grey wolves mostly prefer to live in a pack. The group size is 512 on average. They have a very strict social dominant hierarchy.

The wolves’ were hunted in late 1800 s’ and early 1900‘s in the United States because farmers wanted more land for their cattle’s to graze upon. As farmers were moving out west they felt threaten that the wolves would hunt their cattles so the farmers thought that the best solution would be to take them out of the picture. This was possible because at the time there were no government regulations on hunting....
Over the past several years, the gray wolf, native to the Wisconsin area, has been listed federally as an endangered species due to the graphic and horrific treatment they had received during the industrialization periods of America, when they were frowned upon and hated because they are predatory creatures and did, on occasion, attack livestock and pets. Because the government was encouraging the hunting, including bounties for the animals, the wolves were hunted to near extinction. However, now Wisconsin faces a new problem. With the reintroduction of the wolves to the state, and their continued endangered status federally, the population has increased well beyond expectations, reaching what could be considered a problematic state. A regulated hunt and a population control procedure has become necessary in Wisconsin to protect state's economic endeavors of game, wildlife, and agriculture, and also the wolves themselves, to keep them from overpopulating and facing starvation and lack of land.
1914 began the official war of the wolves. This year Congress officially approves funds for the eradication of wolves, cougars, and other destructive animals. Wolves were declared destructive to agricultural and big game interests and formally hunted. Nearly a century later, in 1995, wolves were reintroduced to Yellowstone National Park and Idaho's Frank Church-River of No Return Wilderness(Phillips, 1996, p.20). The reintroduction of wolves in Yellowstone National Park did not end the debate of whether wolves should stay or go. Advocates for wolf reintroduction say the wolves control elk and deer population numbers; preventing the destruction of ranchers cattle and the land. Opponents say the wolves kill elk and deer that could be hunted. Ranchers fear the wolves will kill their livestock decreasing profits.
The wolf is the largest member of the dog family Canidae, making it a real pest if it goes unchecked in agricultural systems. The wolf is one of the most efficient and effective predators in this region, preying on large ungulates; elk, deer, big horn sheep, moose, and even bison and cattle; however they will eat small mammals if there is no other food source available. Prior to 2002 estimates of the loss of livestock due to wolves were 19 cattle and 68 sheep, however in 2002, 33 cattle, 71 sheep and 1 dog were confirmed killed by wolves (Wyoming Wolf Management Plan, 2003). These kills are significant...
Even though wolves kill livestock and do massive damage, killing wolfs can increase cattle deaths and traps and guns are huge advantage over them.
Wolves used to thrive in the western United States. There was ample game to hunt and plenty of places to live and wander. Until people moved in, wolves were settled. As European settlement expanded to the west, it began to take its toll on the wolves and their habitat. Clearing of the forests came first, which was then accompanied by significant over-hunting in this area (Noceker). Slowly wolves became concentrated into smaller and smaller areas in the west. Finally, they were assumed to be bothers to the ranchers and farmers and maybe a threat to those people who lived in the area.
Hypotheses of the Effects of Wolf Predation Abstract: This paper discusses four hypotheses to explain the effects of wolf predation on prey populations of large ungulates. The four proposed hypotheses examined are the predation limiting hypothesis, the predation regulating hypothesis, the predator pit hypothesis, and the stable limit cycle hypothesis. There is much research literature that discusses how these hypotheses can be used to interpret various data sets obtained from field studies. It was concluded that the predation limiting hypothesis fit most study cases, but that more research is necessary to account for multiple predator - multiple prey relationships. The effects of predation can have an enormous impact on the ecological organization and structure of communities.
During 70 years of absence from the Rockies, the Grey Wolf had been protected under the Endangered Species Act that was passed in 1973. Since the wolf is under the protection of Endangered Species Act a person could be punished with up to a $100,000 fine and up to 1 year in jail for killing a wolf. Back in the 1850's there was a major population increase of the wolves in America, this was due to settlers moving west. These settlers killed more than 80 million bison, the wolves started to scavenge on the carcasses left behind.
...y white fur for fur that cost a lot of money. Some people like to sell their teeth for money or make jewelry. Mostly just for the thrill of it. Also to sell the whole wolf for money or cut off pieces of the wolf like head, ears, paws, and tail as a award for that they killed one. So because of all the stuff that people are doing to kill these wolves are making all them all disappear. There are less ad less. There are not in all 50 states as they use to be, they are reduced down to 7 states and Canada, that is how serious there case is now a day.
This report is all about the gray wolf. Its scientific name is Canis Lupis. Canis is the Latin word for dog. The genus also includes jackals and coyotes. Lupis is the Latin word for wolf. Gray wolves look similar to German shepherds, but the wolf has longer legs and bigger feet. The color of a gray wolf can range from black to white, but shades of gray are the most common. A unique feature about gray wolves is that the farther north you find them, the larger they are. Males can range from (nose-to-tail) five to six and a half feet and females range from four and a half to six feet. The normal life span of a wolf is about thirteen years, but most wolves don’t live past ten years for numerous reasons. Examples include disease, hunters, etc. The wolves that live in Arctic climates have very thick coats of fur that keeps them warm. Wolves, like all canines, have 42 teeth. Their “fangs”, or canine teeth, are used to grab prey and like a hook. These teeth can be as long as two and a half inches.
In the article “The New Threat to Wolves in and Around Yellowstone” written by Jim Robbins, the gray wolf has made a healthy comeback. There is an issue though, officials are now planning a hunting season on gray wolves. Expanding the hunt for wolves around the park poses several issues at the park. The Yellowstone park is where the management protects wildlife so that people can watch and study wildlife. Trophy hunting should be banned in order to help preserve wildlife, give animals a larger lifespan, and to help conservation efforts.
Our freshman class has been studying ecology and the wolf and moose population on Isle Royale this unit. We have gone through packets and models to learn more about how organisms have relations with one another in their physical surroundings. On top of that, we have gone through case studies and videos to learn more about the wolves and moose on the island. Throughout our investigation we had built a graph showing the populations of the moose and wolves. As we reached the end of our unit, our class was presented with a question:are the moose and wolf population on Isle Royale stable? I believe that the two populations are unstable because of the constant temporary disturbances, the inability to calculate a carrying capacity, and the lack of a pattern between predator and prey.
