The ecology of the Pacific Northwest is very interesting. Animals and plants are the reason why it is how it is today. An animal in the Pacific Northwest ecology is the Northern Spotted Owl. This owl is an endangered animal and is one of three subspecies of spotted owls.It is dark to chestnut brown in color with white, round spots all around its neck, back, head, and under parts. Their natural habitats are old-growth forests and these can be found in places that range from northern California, all the way to British Columbia, Canada.
Rising temperatures are already affecting Alaska, where the spruce bark beetle is breeding faster in the warmer weather. These beetles now breed an extra generation each year, this brings more problems, from 1993 to 2003, they ruined (chewed up) 3.4 million acres of Alaskan forest. Melting glaciers and land-based ice sheets also add to rising sea levels. This threatens low-lying areas around the globe with beach erosion, coastal flooding, and also contaminates the fresh water supplies. At
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.
Land species- species adapted to arctic climate at risk. Marine species- species dependent on sea ice, including polar bears, walruses etc. will decline. Carbon cycle changes- replacement of arctic vegetation with more forests will lead to higher productivity and increased carbon dioxide uptake, but methane emissions from warming wetlands and thawing permafrost could counterbalance this positive impact. 4.
A survey financed by the Countryside Alliance showed that in spite of control, 30% of farmers had experienced significant losses from foxes in the preceding twelve months. This figure is supported by the research of an eminent Oxford biologist, Dr David Macdonald, who also found out that the percentage of farmers believing that foxes should be controlled varied between 82.2% in the Midlands and 96.2% in the sheep rearing districts of Exmoor. However I do not think that foxes are pests at all as most of the fox’s feeding habitats are not detrimental to farming – on the contrary, their main prey are rabbits, rats and voles, all of which are considerable pests in the 70% of farmlands given to arable production, so on one hand foxes can be benefit to the farmer. According to the Ministry of Agriculture, predation on lambs by foxes is ‘insignificant’. Studies show that even by farmers’ estimates, only one in two hundred lambs fall victim to a fox, whereas between 10% and 24% of lambs die from hypothermia, malnutrition or disease or are still-born.
Adult male Canada Geese can grow to be 15 pounds, while smaller birds can be as light as 3 pounds (Canada Goose 2011). The average lifespan of a Canada Goose in the wild is 22-24 years. Geese are social creatures and will commonly come up to a human, whether in defense of their territory or in search of food (Sibley, D.A. 2000). Their general habitat throughout North America is always near some body of water, and Canada Geese have shown that they can survive in climates from tundra to temperate
Ice in Motion In the article Ice in Motion by Alexandra Witze, the author essentially examines "ice dynamics", the movement and melting of glaciers, and the consequences of these changes to our environment currently and in centuries to come. Greenland and Antarctica are home to some of the world's largest glacial masses; this article also provides details of multiple studies conducted in those regions. To provide some perspective: Greenland loses as much ice in a year as is in the entire Alps. Antarctica's Pine Island Glacier is a major contributor to rising sea levels and recently produced an iceberg of 720 square kilometers - approximately eight times the size of the island of Manhattan. (Witze, 2011).
The Amur leopard is a distinct subspecies of leopard and one of the most endangered big cats on Earth. The situation surrounding its conservation is critical, and its population in the wild is small and rapidly decreasing in size. Though it is far more endangered than the Amur tiger, it receives much less attention than its close cousin and few have heard of it or its precarious state. The Amur leopard’s habitat now spans about 5000 square km and the last remaining viable wild population consists of less than 40 individuals in the province of Primorsky Krai, Russia. The leopard’s habitat once extended through north-eastern (‘Manchurian’) China, including Jilin and Heilongjiang provinces, and throughout the Korean peninsula.
Many things are hindering this species ability to survive. Amur leopards are endangered due to conflict with humans, habitat loss and fragmentation, poaching/illegal trade, inbreeding and vulnerable population size, and a scarcity of prey. Territory loss is one of the main reasons that the Amur leopard is critically endangered. The Amur leopard’s habitat is mostly temperate broadleaf forests and the mountains. Human induced fires are a main threat.
Through out the seasons, the temperature greatly varies. This biome has very cold winters and hot summers. Deciduous forests are homes to many animals like the Black Bear, Fox, Brown Bear, Cardinal, Gray Squirrel, and Raccoon. Each animal must have special adaptations to live in this biome. Many animals hibernate through out the long and cold winters.
