Abstract Predators are animals that kill for their food; they must do this in order to survive. There has been controversy about predation in some areas including the re-introduction of wolves into the Yellowstone National park area and other areas. Predator-prey relationships are both beneficial and detrimental to some species. The weakest and unhealthiest become dinner for those predators and also become a positive thing for the species that only the strongest of the herd will survive
white in the winter and brown in the summer; the ability to accumulate thick deposits of fat during the short growing season; hibernation; and migration. Some of the animals that are found living in the tundra are lemmings, voles, caribou, artic hares, squirrels, artic foxes, wolves, polar bear, ravens, snow buntings, falcons, loons, ravens, sandpipers, terns, snow birds, mosquitoes, flies, moths, grasshoppers, black flies, artic bumble bees, cod, flatfish, salmon, and trout.

A biome, also known as life zones, consists of all plants, animals, and other organisms, as well the physical environment in a particular area. A biome is characterized by its’ plant life, climate, and location. The climate and physical features determine the boundaries of a biome. A biome is made up of many different ecosystems. The ecosystems tend to have the same pants and animals as neighboring biomes around the boundaries. The major biomes are the tundra, taiga, tropical rain forest, temperate
material, gray wolves will feed primarily on large ungulates, and amongst the mesocarnivores, predator body mass will correlate with prey size. In particular, the larger coyotes and bobcats will feed primarily on medium-sized mammalian prey, such as snowshoe hares and cottontail rabbits, and the smaller red foxes, fishers, and American martens will feed primarily on smaller prey, such as voles, mice, and squirrels, along with porcupines in the fisher diet. Methods Study Area The 1,400 square kilometer
