A bison is a large bovine in the genus Bison within the tribe Bovini. Two extant and numerous extinct species are recognised.
The coyote is a species of canine native to North America. It is smaller than its close relative, the wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia. The coyote is larger and more predatory and was once referred to as the American jackal by a behavioral ecologist. Other historical names for the species include the prairie wolf and the brush wolf.
The red wolf is a canine native to the southeastern United States. Its size is intermediate between the coyote and gray wolf.
The wolverine, also referred to as the glutton, carcajou, or quickhatch, is the largest land-dwelling species of the family Mustelidae. It is a muscular carnivore and a solitary animal. The wolverine has a reputation for ferocity and strength out of proportion to its size, with the documented ability to kill prey many times larger than itself.
The American bison, also called the American buffalo or simply buffalo, is a species of bison native to North America. It is one of two extant species of bison, alongside the European bison. Its historical range, by 9000 BCE, is described as the great bison belt, a tract of rich grassland that ran from Alaska to the Gulf of Mexico, east to the Atlantic Seaboard, as far north as New York, south to Georgia, and according to some sources, further south to Florida, with sightings in North Carolina near Buffalo Ford on the Catawba River as late as 1750.
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation and parasitoidism. It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators.
Elk Island National Park is a national park in Alberta, Canada, that played an important part in the conservation of the Plains bison. The park is administered by the Parks Canada Agency. This "island of conservation" is 35 km (22 mi) east of Edmonton, along the Yellowhead Highway, which goes through the park. It is Canada's eighth smallest in area but largest fully enclosed national park, with an area of 194 km2 (75 sq mi).
The wood bison or mountain bison, is a distinct northern subspecies or ecotype of the American bison. Its original range included much of the boreal forest regions of Alaska, Yukon, western Northwest Territories, northeastern British Columbia, northern Alberta, and northwestern Saskatchewan.
The Great Plains wolf, also known as the buffalo wolf or loafer, is a subspecies of gray wolf that once extended throughout the Great Plains, from southern Manitoba and Saskatchewan in Canada southward to northern Texas in the United States. The subspecies was thought to be extinct in 1926, until studies declared that its descendants were found in Minnesota, Wisconsin and Michigan. They were described as a large, light-colored wolf but with black and white varying between individual wolves, with some all white or all black. The Native Americans of North Dakota told of how only three Great Plains wolves could bring down any sized bison.
Surplus killing, also known as excessive killing, henhouse syndrome, or overkill, is a common behavior exhibited by predators, in which they kill more prey than they can immediately eat and then they either cache or abandon the remainder. The term was invented by Dutch biologist Hans Kruuk after studying spotted hyenas in Africa and red foxes in England. Some of the other animals which have been observed engaging in surplus killing include orcas, zooplankton, humans, damselfly naiads, predaceous mites, martens, weasels, honey badgers, jaguar, leopards, lions, wolves, spiders, brown bears, American black bears, polar bears, coyotes, lynxes, minks, raccoons and dogs.
Clarence Tillenius, LL. D. was a Canadian artist, environmentalist, and advocate for the protection of wildlife and wilderness.
The history of wolves in Yellowstone includes the extirpation, absence and reintroduction of wild populations of the gray wolf to Yellowstone National Park and the Greater Yellowstone Ecosystem. When the park was created in 1872, wolf populations were already in decline in Montana, Wyoming and Idaho. The creation of the national park did not provide protection for wolves or other predators, and government predator control programs in the first decades of the 1900s essentially helped eliminate the gray wolf from Yellowstone. The last wolves were killed in Yellowstone in 1926. After that, sporadic reports of wolves still occurred, but scientists confirmed that sustainable wolf populations had been extirpated and were absent from Yellowstone during the mid-1900s.
The Interior Alaskan wolf, also known as the Yukon wolf, is a subspecies of gray wolf native to parts of British Columbia, the Northwest Territories, Interior Alaska and Yukon.
Nemiskam National Park was created north of the community of Nemiskam in south central Alberta, Canada, in 1922. The park was closed and delisted in 1947. The first Park Superintendent was Edgar McHugh. Nemiskam is a First Nations word meaning "between two valleys", referring to the Chin Coulee and Etzikom Coulee on either side of the former community.
Throughout the 18th and 19th centuries, the plains bison and wood bison in Canada were hunted by nomadic indigenous hunters and white hunters alike. By the 1850s, the bison was nearly extinct, spurring a movement to save the few herds that remained. Federal government wildlife policy evolved from preservation of wilderness to utilitarian, scientific conservation and management of bison populations. The goals of these policies were often contradictory: to simultaneously preserve wildlife, promote recreation, commercialize the bison, and assert state control over Aboriginal Canadians. Bison conservation efforts were shaped by the federal government's colonialist and modernist approach to Canada's North, the management of national parks and reserves, and the influence of scientific knowledge.
The grizzly bear, also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America.
Valerius Geist was a Canadian biologist and a professor emeritus in the Faculty of Environmental Design at the University of Calgary. He was a specialist on the biology, behavior, and social dynamics of North American large mammals, and well respected on his views of Neanderthal people and behavior.
The eastern coyote is a wild North American canine hybrid with both coyote and wolf parentage. The hybridization likely first occurred in the Great Lakes region, as western coyotes moved east. It was first noticed during the early 1930s to the late 1940s, and likely originated in the aftermath of the extirpation of the gray wolf and eastern wolf in southeastern Ontario, Labrador and Quebec, thus allowing coyotes to colonize the former wolf ranges, and mix with the remnant wolf populations. This hybrid is smaller than the eastern wolf and holds smaller territories, but is larger and holds more extensive home ranges than the typical western coyote.
The boreal woodland caribou, also known as Eastern woodland caribou, boreal forest caribou and forest-dwelling caribou, is a North American subspecies of reindeer found primarily in Canada with small populations in the United States. Unlike the Porcupine caribou and barren-ground caribou, boreal woodland caribou are primarily sedentary.
The brown bear is one of the most omnivorous animals in the world and has been recorded to consume the greatest variety of foods of any bear. Throughout life, this species is regularly curious about the potential of eating virtually any organism or object that they encounter. Certainly no other animal in their given ecosystems, short perhaps of other bear species and humans, can claim to feed on as broad a range of dietary opportunities. Food that is both abundant and easily obtained is preferred. Their jaw structure has evolved to fit their dietary habits. Their diet varies enormously throughout their differing areas based on opportunity. In spring, winter-provided carrion, grasses, shoots, sedges and forbs are the dietary mainstays for brown bears from almost every part of their distribution. Fruits, including berries, become increasingly important during summer and early autumn. Roots and bulbs become critical in autumn for some inland bear populations if fruit crops are poor. The dietary variability is illustrated in the western United States, as meat made up 51% of the average year-around diet for grizzly bears from Yellowstone National Park, while it made up only 11% of the year-around diet for grizzlies from Glacier National Park a few hundred miles to the north.
