The Arctic wolf is a subspecies of the gray wolf. This mammal, also called polar wolf and white wolf, is part of the small group of animals that inhabit the hostile Arctic ecosystem. Since some years ago, the polar wolf’s existence has been threatened, and its population has diminished. Some of the factors that have caused the endangering of the wolf are the destruction of its habitat and the industrial development. Lately, many organizations have started campaigns to create awareness of the Arctic wolf’s importance and prevent its potential extinction.

As it name suggests, the white wolf has a thick layer of pale fur that gives him the ability to camouflage in its snowy habitat. However, Arctic wolves with fur colored with pale shades of brown, gray and red might also be found. The polar wolf’s unique coloration distinguishes it from other subspecies of wolves. The white wolf has a very similar shape to the one of the common gray wolf, but it tends to be smaller: it has a length ranging from 1 to 1.8 meters and a weight of 45 to 70 kilograms. It also has ...
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 maned wolf is omnivorous and is a secondary consumer alike the Coyote and Darwin's fox. It has a similar diet to the coyote’s, since it feeds on small and medium sized mammals such as rodents, birds, fish and rabbits. Unlike the coyote and Darwin's fox, the maned wolf does not have any specific enemies or predators, but it may be attacked or even killed by feral dogs.
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.
They survive in some of the coldest places on earth, they have a number of anatomical, behavioural and physiological adaptations that allow them to do this successfully. Arctic wolves live for around 7 to 10 years in the wild.
The North American Whitetail is typically 3 1/2 to 4 feet tall at the shoulder, and can range from 100 to 220 pounds. The size of the deer depends on the area you find the deer and how much food there is in that area. The males (or bucks) typically have antlers that they shed seasonally. The females (or does) usually do not have antlers, but can on rare occasions. There are some very definite qualities that make it easy to distinguish the white tail from one of its close relatives, like the mule deer. The whitetail is a reddish brown color in the summer and a grayish brown color in the winter. If you ever see a whitetail in the wild, you will quickly see how they got ...
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 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.
One of the biggest reasons for the reintroduction of wolves back into Yellowstone was that they had originally roamed from Yellowstone all the way down to Mexico. While a lot of people were in favor of the reintroduction of the wolves, there were many who were against it. The main people who were against the reintroduction of the wolves back into the park were the ranchers who made a living in the areas surrounding the park.
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.
Gray wolves range in color from black, brown, gray, and white and also look like a grown German Shepherd. They are well known for traveling in family sizes from 7-9 wolves, led by the alpha male and have a mate. They are a fierce animal that has been researched extensively because of their unique qualities and that they are near extinction. Early settlers, all the way back in the 1700s, tried to rid these marvelous creatures from the North American continent, which almost led to their extinction. They poisoned, trapped, furred, shot and killed all the wolves that posed a threat to their lands and livestock.
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.
Canis Lupus, the Latin term for the “North American Wolf”. A meat eating mammal with the capability of weighing up to 180 pounds and reaching a height of sixty-three inches, the wolf is easily the largest member of the canine family. Over 500,000 wolves once lived in harmony, roaming the Northern Americas alongside the Native American tribes and the rest of the ecosystem. Wolves live in packs, a pack essentially being a family. While the average size of a pack is six to ten, the largest confirmed pack recorded in North America can be found in Yellowstone National Park where the “Druid Pack” numbers thirty-seven strong and counting. There have been alleged reports of a pack that attacked a small Russian town killing thirty horses in just four days. This pack numbered up to almost 400 members. Animal experts remain suspicious due to the fact that this number is almost fifteen times the size of an average sized pack. Wolves heavily rely on their pack. Every member of the pack has a specific job that benefits the pack, without the pack, death would be almost imminent. The pack is set up as a hierarchy, with an alpha male and an alpha female. The alphas get the best of everything, the best part of the kill, the best sleeping spot, and the breeding rights. When hunting, one member will scout ahead and will determine the weakest member of the herd. Once determined, the rest of the pack will chase the animal down and either takes it down on the run or chase it until it tires out. Unlike many predators in the animal kingdom, wolves eat their prey alive. While wolves are known for their spine tingling howls, the howl is not the only way they communicate. “Wolf Language” so to speak, consists of many grunts, snarls, growls, yips, and whines....
The fur is generally a medium grey, darker on the hind part of the back where the black-tipped hair becomes wavy. Legs, paws, and the back of the ears are more yellowish in color; the throat, belly, and the inside of the ears are whiter. The tail, is darker on top and lighter on the underside. The color also depends of the season, and healthiness of the coyote. The coyote's fur is long and soft and well suited to protect it from the cold.
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...
The Arctic region is home to a variety of valuable animals and plants, including polar bear, seal, and so on. The ecosystem of the Arctic region is fragile because these animals are evolved to live in extreme conditions. With the climate change, many animals are endangered. Ice is the habitat of polar animals because they have to rely on sea ices for resting, food, and reproduction. With the climate change and the decrease of sea ice, the number of polar animals is decreasing and their health is threatened. For example, the average weight of female polar bears in 1980 was about 650 pounds, but the number reduced to about 500 pounds in 2004 (Djoghlaf 15). The earlier breakup and later condensation of sea ice shortens the hunting season of polar bears. Polar bears mainly feed on seals that indwell icy land. The melting ice reduces the number of seals and food intake of polar bears. In addition, polar bears are used to living in ice caves. The rising temperature causes the collapse of ice caves, which can kill baby bears. The climate change is negatively affecting the biodiversity in the region and will definitely harm the ecosystem
