Geographic distribution bears in North America

Bears are carnivoran mammals of the family Ursidae. Only eight species of bears are living on our planet. But they are widespread in the Northern Hemisphere and partially in the Southern Hemisphere. There are three species of bears inhabit North America. The most regular is the American black bear (Ursus americanus). It can be observed in all provinces and territories in Canada except Prince Edward Island and 40 of the 50 states of the USA. There are about 900 000 black bears lives in North America. The grizzly or brown bear (Ursus arctos), lives in British Columbia, Alberta, the Yukon and Northwest territories as well as in the states of Washington, Idaho, Montana, Wyoming, Montana, Idaho. In North America, approximately 57 000 bears live. Due to low human activity in its remote Arctic ecosystems, the polar bear (Ursus maritimus) conserves more of its original region than any other persisting large carnivore. About 25 000 polar bears live in the northern areas of Canada, American Ala

Basically dead cattle in Portugal must be buried or incinerated as quickly as possible, which reduces food available for vultures. Via

Last of the Wild

The last of wild represents the least influenced areas of major terrestrial biomes. Most wild in each biome is defined as areas with Human Footprint Index values less than or equal to 10. The map shows the distribution of what remains the least influenced areas in each biome. Source:

The distribution of cheetah

Number of species of birds by country

Birds live in most terrestrial habitats and on all seven continents, reaching their southern extreme in the snow petrel's breeding colonies up to 440 kilometers (270 miles) inland in Antarctica. The highest bird diversity occurs in tropical regions. It was earlier thought that this high diversity was the result of higher speciation rates in the tropics; however recent studies found higher speciation rates in the high latitudes that were offset by greater extinction rates than in the tropics. Several families of birds have adapted to life both on the world's oceans and in them, with some seabird species coming ashore only to breed and some penguins have been recorded diving up to 300 meters (980 feets) deep.

World distribution of snakes

Source: There are over 2,900 species of snakes ranging as far northward as the Arctic Circle in Scandinavia and southward through Australia. Snakes can be found on every continent except Antarctica, in the sea, and as high as 4,900 meters  (16,000 feet) in the Himalayan Mountains of Asia. There are numerous islands from which snakes are absent, such as Ireland, Iceland, and New Zealand.

The Disappearing Rivers of the U.S.

The rivers of the American West have shaped the pattern of human development across the region. In turn, human activities are rapidly changing the rivers that sustain them. Today, nearly half - 49% - of all river miles in the West are no longer in their natural state. In all, 140 thousand miles of rivers in the American West – a distance long enough to circle the Earth nearly 6 times – have been modified by dams, diversions, suburban sprawl, legacy mines, and other human development.

Global Distribution of Penguins

Penguins are a group of aquatic, flightless birds. They live almost exclusively in the Southern Hemisphere, with only one species, the Galapagos penguin, found north of the equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage, and their wings have evolved into flippers. Most penguins feed on krill, fish, squid and other forms of sea life caught while swimming underwater. They spend about half of their lives on land and half in the oceans. Although almost all penguin species are native to the Southern Hemisphere, they are not found only in cold climates, such as Antarctica. In fact, only a few species of penguin live so far south. Several species are found in the temperate zone, and one species, the Galápagos penguin, lives near the equator. The largest living species is the emperor penguin on average adults are about 1.1 m (3 ft 7 in) tall and weigh 35 kg (77 lb). The smallest penguin species is the little blue penguin, also known as

Protecting the Arctic

Many governments and nongovernmental organizations are collaborating in an attempt to protect the marine ecosystems of the Arctic in the face of climate change and increasing pressure from industry. This task is complicated by the differervLctesignations of protection as well as by the numerous governing bodies that have created these designations. ^ Marine Protected Areas of the Arctic are being explored to determine their current state of protection within the larger Important Marine Areas. Important Marine Areas included in this analysis have been identified by four different organizations and/or countries working in the Arctic. They Are 1) Convention on Biological Diversity’s Ecologically or Biologically Significant Areas (CBD EBSA) 2) Fisheries and Oceans Canada’s Ecologically and Biologically Significant Areas (Canada EBSA) 3) International Union for Conservation of Nature-National Resources 4)  Arctic Council’s Arctic Marine Shipping Assessment (AMSA IIC).
