It lives its whole life above the northern tree line in the Arctic tundra, roaming across North America and Greenland but not extending into mainland Europe or Asia. It is a kind of grey wolf, though is no longer thought to be a distinct subspecies, it is the least threatened of all grey wolves and its subspecies populations as they live in isolated regions that rarely bring them into contact or conflict with man. 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. Arctic Wolf Adaptations: Small ears to reduce their surface area to volume ratio (anatomical) - Compared
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 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 second level in the hierarchy of grey wolves is beta. The betas are subordinate wolves that help the alpha in decisionmaking or other pack activities. The beta wolf can be either male
Many hundreds of years ago wolves roamed the entire North American continent with no barriers and very few predators. As settlers moved into the United States, wolves became more and more scarce in the wild of America. As the wilderness areas of the United States declined, so did the population of the wolf, until there were only a few spots in the wild where wolves could still be found.
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 winter will last 8 to 10 months followed by the short and much less cold summer. During the summer some lower areas of the Tundra will defrost at which point most of the flora and fauna will start to creep out of hiding. The few summer months are used by many animals such as the polar bear, to mate and to prepare for the once again oncoming winter. During the winter months, most everything remains frozen. Many of the animals migrate south for the winter whereas some stay behind or even group together for ritual group suicide (lemmings).
The arctic fox lives in aa habitat that can be very cold and to overcome the weather they have a number of behavioural adaptations. When the temperature drops very down they start to dig burrows under the snow. It is like a tunnel where they can isolate themselves and avoid the weather. This also protects them from the strong wind. The temperature inside the tunnel is higher that external
Wolves had live throughout parts of the world for thousands of years before humans just kept rising in population and minimizing the wolves’ population through the expansion of their territories for farm agriculture and industrialization. It is only in the United States where humans completely annihilated wolves; they did this by hunting the wolves down until the last wolf was killed in 1926. However, in 1995, 14 wolves were caught from Canada and release into Yellowstone National Park. This makes it almost 70 years since the wolves have been reintroduced back into Yellowstone National Park (17 July 2009)
It is believed that polar bears live an average of 15 to 18 years, though some bears have tagged in their early 30s. In some zoo’s bears have been known to live up to the mid 30s. There is only one individual bear that has been known to have lived up to the age of 40.
Gray wolves have large paws with fleshy pads and claws for traction and can spread to provide better support in snow. Wolves need adaptations so that they can do stuff others can't do. One physical characteristics wolves have is that they can hunt very good. One instinct that wolves have is that they have super speed so they can run fast with the pack. They also have super smell so that they can smell what’s around and smell their prey. They also have super hearing so that they can hear if something or someone is coming and it is good for hunting. They also have super strength because then they can fight off other animals trying to attack them. Wolves are not primary or secondary consumers. Wolves also have to hunt to survive because that's how they eat. They survive if they don't know how to hunt food down because then they will just starve to
Where do wolves live, what is their natural habitat along with their physical features? Most wolves live in the lower 48 states. Few wolves live in Europe many in Alaska, Canada, and Asia. Wolves used to live all throughout North America but much of the wolf population was killed. Now mainly the wolves that live in the North America live more up North. Lots of them live in the Great Lakes or Northern Rockies. There are about 104 wolves living in 11 packs in Yellowstone. Wolves usually require large mountainous and forest like terrain. The average male wolf will grow to about 6.6 feet long. Wolves have large canine teeth and a very powerful jaw. And they stand about inches tall when fully grown. They also live in the forest because of the dense
States and southern Canada. In the west, the species was found from Mexico to California.
There are thousands of Arctic foxes living in Canada, a country located in North America, the third largest continent in the world. They spend a lot of their time in below freezing temperatures in the tundra, a massive, mostly treeless, wilderness. Many plants cannot survive the cold weather, but there are yellow poppy flowers , bearberry shrubs , and Labrador tea plants in the
