Grey wolves were removed from USA’s Yellowstone National Park in 1926. A big impact of removing wolves were how the Aspen trees were slowly disappearing.After the wolves were gone beavers were scarce in the northern range, numbers of songbirds and habitats were reduced. The elk population skyrockets because the bears and the coyotes were left to hunt the elk but they do not kill as many elks as the wolves did. When the reintroduction of the wolves in 1995 there was a drastic difference in the landscape. The absent of the wolves had a extreme impact to the ecosystem of Yellowstone National Park. removing wolves caused missing forest and eroding riverbanks. Lamar river lost soil and sediments were pushing on top of the soil. Since
This makes them seem less menacing and scary like the first article makes them look. Sharon Levy says in part "It is only in the two decades that biologists have started to build a clearer picture of wolf ecology….Instead of seeing rogue man-eaters and savage packs, we now understand that wolves have evolved to live in extended family groups.." (ll 19-22) This article also explains the positive overall effects of the wolves moving back to Yellowstone. Not only did the wolves have a new home filled with beautiful elk for prey they were also protected from hunters. This changed the attitude of the wolves as well as their population, of course their population grew and stayed more
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.

National Parks are the cornerstone of every country because it preserves the rich cultural and natural resources of a nation, such as Yellowstone in the United States of America. Yellowstone National Park is the World’s First National Park which brings millions of attraction each year, it is larger than Rhode Island and Delaware combine and have over a thousand species of plants and animal (Yellowstone Media). However, a very important type of species has been missing in Yellowstone National Park for a very long time. Wolves, which got reintroduce back into Yellowstone National Park, should stay there because without them the ecosystem would be out of balance.
When the reintroduction of wolves began in the state of Wisconsin, a goal of 350 wolves was set, and this number was reached successfully in a short amount of time. Once this was reached, however, the population continued to rise dramatically and exponentially, and is now in the upper 600s (Allen). The problems now come down to a few simple questions that have complex answers. Will a regulated hunt get out of control, and a repeat of the past begins? Are the wolves posing any sort of threat in the present? Who or what would a hunt benefit? First, the issue of the past must be addressed. Back in the earlier years of the United States, wolves roamed free, and when farmers moved their livestock into what was then the wolves' territo...
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.
Wolves have always been a symbol of the wild, free in spirit and roamers of the land. These animals are considered majestic and protectors of the wilderness. They have always roamed the western United States, although their population has fluctuated over time. Over the past 10 years wolf reintroduction into Yellowstone National Park has been a controversial topic to those of the United States. As of 1995, wolves have been reintroduced into the park. This has come with some strong opposition and yet has prevailed. The future of the wolf in Yellowstone park is now looking bright, although not certain since there still are those who want them banished again.
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.

The habitat of the Arctic wolf is a very harsh place. The temperature must be below zero degrees. There are tundra, rolling hills, glacier valleys, ice fields, shallow lakes, and green flatlands (Arctic/Antarctic: The Arctic Wolf). These snowy white creators don’t have that many places to live. Arctic wolves used to be everywhere in North America, but sadly now they are reduced to Canada, Alaska, Idaho, Michigan, Minnesota, Montana, Wisconsin, and Wyoming (Arctic/Antarctic: The Arctic Wolf). Arctic wolves are one of the most dangerous types of wolves; people need to find a way to save them and their habitat before they disappear forever.
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.
The controversy surrounding the reintroduction of the wolves are many from both sides. Some local farmers are against it because some wolves hunt their animals. However, if the farmers can prove their animal was attacked by a wolf, then the government would reimburse them for the animals value. Another problem is that some taxpayers are against the reintroduction because it cost them money to get the wolves back into the park. Another issue for taxpayers is that they have to pay for the damage the wolves do to the farmer’s animals.
It is early in the morning with the majestic Elk bugles in the distance. The sun kisses the tops of the peaks with the most beautiful gold, and paints the clouds rose red. Men and women who enjoy the outdoors, whether it is hunting or just hiking, help make these types of moments possible. Hunting and the ecosystem is tied closely to conservation of land and animals. The articles on “Hunting and the ecosystem” written by the South Dakota Game Fish and Parks Department (SDGFP), and “Facts and statistics on wildlife conservation” written by Roger Holmes, director of the Fish and Wildlife, touch on how hunting is important to the environment to keep a good balance in the ecosystem.
In comparison, wolves were gone from Yellowstone for more than 70 years. While they were gone, the ecosystem continued to function properly. With the gray wolf returning, the ecosystem improved. Yellowstone depends on the gray wolf to hel...
Studies show that wolves play a significant role in maintaining healthy ecosystems, and could even help stave off some of the effects of climate change. They help keep large animal herd populations in check, which can benefit numerous other plan...
