After the wolves were reintroduced it began to restore the trophic cascade. The reduced browsing because of the altered behavior allowed increase in the recruitment of woody plants like Aspen (Populus tremuloides) and willow (Salix spp.) (Ripple and Beschta 2012). Without the elk decimating woody plants populations they were able to regenerate. This resulted in an increase in multiple species native to the park. These species included bison (Bison bison), beaver (Castor canadensis), and bears (Ursus arctos). The relative abundance and richness of 6/7 species of songbirds also increased because of the increased recruitment (Ripple and Beschta 2012). The wolves also have a positive effect on the age/sex structure. By concentrating on calves and older females they consistently eliminate the older sicker elk that are less suitable to survive. The wolves rarely prey on females in their reproductive prime or full grown males. The reintroduction has also had a positive effect on the bison population. The elk and bison share 80% of the same browsing food source. As elk are driven from their preferred browsing areas the bison are able to exploit the areas with the most nutritional…
There are squirrels, deer, elk, and birds. If you hunt them they can provide a source of food. You can also use them for their fur.…
The Grey Fox, also known as the “Tree Fox” is just one of the animals that live in the Chaparral biome. The baby Grey Fox is called a kit or a pup. The Grey Fox is an animal closely related to the dog, because of their bushy tails. The back of the Grey Fox is a whitish grey color, while the muzzle is black and has a black stripe. The Grey Fox as an adult can weigh anywhere from seven to eleven pounds.…

One of the animals that live in the tundra, the snowy owl, is very interesting! It is very different from other owls. The snowy owl's niche is to reduce the competition for food. It hunts for prey when other owls are asleep so they will not have to watch out for others. It is a secondary consumer that eats mice.…
A deciduous trees is one that experiences an annual period in which all leaves die and usually fall from the tree, due to either a cold season or a dry season. Example: Oak…
The temperate deciduous forest locations are in the eatern united states, canda, western russia and parts of china and japan. As many seasons in a temperate deciduous forest there are four seasons which are spring, summer, fall and winter. Just as us. In a temerate forest the soil is very fertile. In a temperate forest there are plants, mosses, and fern. As in the tpye of trees there are maple, oak and birtch. The animals in this type of forest has to adapt in cold weather such as the red fox, hawks, woodpecker and cardinals. One of the main threats in a temperate forest is the acid rain because it can harms the animals. humans and the trees.Which mean this could destroy the food…
It has lots of elk and deer and black bears in the mountains and on the forest side. There are over 260 maintained trails so that means you will see the animals - foxes, raccoons and other animals. The animals have to blend in and survive on their…
Most only use the tundra as a summer home due to the harsh conditions of the winter but some animals that can be found in the Arctic tundra are caribou, musk ox, Arctic hare, Arctic fox, snowy owl, lemmings, and polar bears. Animals that live in the tundra have special adaptations to survive. Some adapt by having babies and raising their young in the summer. A lot of animals hibernate.…

-Moist deciduous and semi-evergreen seasonal forests, receive high overall rainfall with a warm summer wet season and a cooler winter dry season. Some trees in these forests drop some or all of their leaves during the winter dry season.…
The Great Bear Rain Forest consists of 64, 000 square kilometres of pure nature, in the coast of British Columbia. It is one of the rarest forest ecosystems on the plants, where trees grow to be over 1000 years old and partakes in being a home to a healthy population of grizzly bears and black bears rare white “Spirit” bears and wild salmon. In the Great Bear Rainforest the towering trees, fjords, islands, mountain slopes and estuaries support a rich diversity of plants and wildlife. Bears, wolves, mountain goats, Sitka deer, salmon and six million migratory birds are found here.…
How is our changing view of human population in the Americas prior to European contact impacting our view of North American ecology and our approaches to natural resources management? The ecology of North America prior to european contact was much different than we previously thought. We thought that their were very few Native Americans and that they lived in small colonies and had very little impact on their surroundings. When in reality there were millions of them, that lived in huge cities. They also had huge impacts on the environment. The early Americans displayed advanced techniques in the movement of goods around the continent. The movement of goods can be seen in artifacts that are similar but found thousands of miles away from each…
The wolf is truly a special animal. As the most widely distributed of all land mammals, the wolf, formally the gray wolf (Canis lupus), is also one of the most adaptable. It inhabits all the vegetation types of the Northern Hemisphere and preys on all the large mammals living there. It also feeds on all the other animals in its environment, scavenges, and can even eat fruits and berries. Wolves frequent forests and prairies, tundra, barren ground, mountains, deserts, and swamps. Some wolves even visit large cities, and, of course, the wolf's domesticated version, the dog, thrives in urban environments.…
