Although, a lot of the forests are being cut down by timber companies. This has been the main reason for the owl’s endangerment. The United States government declared the Northern Spotted Owl endangered in the year of 1990. This made it illegal to log in forests inhabited by the Northern Spotted Owl or thought to be inhabited. That created a debate between loggers and the United States government.
Some of the animals in the taiga hibernate in the winter, some fly south if they can, while some just cooperate with the environment, which is very difficult. Taiga is the Russian word for forest and is the largest biome in the world. It stretches over Eurasia and North America. The taiga is located near the top of the world, just below the tundra biome. The taiga is found throughout the high northern latitudes, between the tundra, and the temperate forest, from about 50°N to 70°N, but with considerable regional variation.
However, [that is not the case today.] [U]nusually hot, dry summers and mild winters in central British Columbia during the last few years, along with forests filled with mature lodge pole pine, have lead to an epidemic”(Natural Resources Canada). Although, before you can really understand how serious of an issue this epidemic is, you must first know how something as seemingly insignificant as a pine beetle, can cause so much damage, and what the three most destructive effects of this beetle infestation are. The most devastating effects from the pine beetle infestation include; the destruction it has caused throughout BC already, the devastating Co2 impact it has on Canada, and the downward spiral it has put on the forestry economy. In order to better understand the effects that the mountain pine beetle has on BC, it is first important to know a bit about the beetles and how the attack begins to how it ends on each tree they infest.
Northern forests offer the lowest human density of any tiger habitat, and the most complete ecosystem. The vast woodlands also allow tigers far more room to roam, as Russia's timber industry is currently less extensive than that of many other countries. Tigers are the largest of all wild cats and are renowned for their power and strength. There were once eight tiger subspecies, but three became extinct during the 20th century. Over the last hundred years, hunting and forest destruction have reduced overall tiger populations from hundreds of thousands to perhaps 3,000 to 5,000.

D. Animals of the Savanna 1. Aardwolf (__________________________) a) Long, furry hyena that has long front legs and short front legs b) Carnivore but also an __________________. c) Feeds mostly on Harvester termites, Insect Larvae, and eggs of ground nesting birds d) Has a rancid odor to that of a __________.
These areas may be drier than wetland areas, but life is still abundant. As you get higher in elevation, you begin to leave the montane areas and enter the subalpine ecosystem. The bent and twisted spruce and fir trees say that the top of the mountain has very hard winters and summers. There are a lot of animals in the Rocky Mountain National Park. There are elk, mule deer, moose, bighorn sheep, coyotes, black bears, cougars and hundreds of smaller animals that live in the park.
Also, since new species of plants have invaded the arctic some animals can’t adapt to them, like the Caribou which numbers have decreased. 4. If climate change continues then half of the arctic tundra could be gone replaced by trees and lush vegetation by 2050. This would cause most plant
Polar bears are the apex predator in Arctic marine ecosystems and are exposed to high levels of pollutants that are magnified with each step higher in the food web. Most of the pollution in the Arctic is transported northward by the large rivers draining into the Arctic and on wind and ocean currents that bring pollutants from southern latitudes. The pollutants of most concern are organochlorines that are, or were, used in industry or as pesticides. A key characteristic of the pollutants is that they are persistent in the environment and resist degradation. Unfortunately, many of the organochlorine pollutants are lipophilic or "fat loving" and bond tightly to fat molecules.
The Arctic Tundra is such an extreme environment where the temperatures can stretch below the negatives and the harsh winds don’t make it much easier. These social animals which live in groups of seven to ten individuals this helps greatly with survival helping them greatly with survival (Mech, 2006). Canis lupus arctos is the scientific term for the Arctic wolf (Klappenbach, 2008).The class of this special animal is Mammalia the reason for this is that as that they have 3 middle ear bones, hair, and the production of milk by modified sweat glands called mammary glands. The Order is Carnivora the reason for this is that they feast on the meat (Alpha of WolfSpirits, 2011). The family it falls under is Canidae this is the biological family of carnivorous and omnivorous mammals.
(Endangered Species List) The Polar Bears live in an Arctic ecosystem as they rely on sea ice for their habitats where they can live twenty to thirty years. However, although these excellent swimmers prefer ice islands, edges of floating ice and ice floes they can occasionally be found on land located in the Arctic Circle. (Glick. D 2006) The endangerment of the Polar Bear has a negative effect on biodiversity as it will make negative changes on the Arctic food web. The Polar Bear is at the top of the food web in the Arctic and relies heavily on seals as their main food source,
