Peltigera Retifoveata
''Peltigera retifoveata'' is a species of foliose lichen in the family Peltigeraceae. It is found in Scandinavia, western Eurasia and western North America, where it grows on the ground and amongst mosses. Taxonomy Because of its thallus surface texure, ''Peltigera retifoveata'' is a member of the species complex centred around '' Peltigera canina''. It was formally described as a new species in 1985 by the Finnish lichenologist Orvo Vitikainen. The type specimen was collected by Vitikainen from Juuma (Kuusamo, Finland) at an elevation of , where it was found growing on the ground among mosses. One vernacular name used in North America is "sponge pelt". Description The thallus of ''P. retifoveata'' grows up to about in diameter, comprising individual that are about long and wide. The thallus surface is thickly tomentose near the margins, but becomes smoother ( near the centre. The thallus underside features thick, pale, tomentose veins, with white and pit-like i ...

Wells Gray Provincial Park
Wells Gray Provincial Park is a large wilderness park located in east-central British Columbia, Canada. The park protects most of the southern, and highest, regions of the Cariboo Mountains and covers 5,250 square kilometres (524,990 hectares or 1.3 million acres). It is British Columbia's fourth largest park, after Tatshenshini, Spatsizi and Tweedsmuir.Neave, Roland (2015). ''Exploring Wells Gray Park'', 6th edition.

Topography The boundaries of Wells Gray Park encompass 60 percent of the drainage basin of the Clearwater River and most water that originates in the park flows into this river. The northern two-thirds of the park is extremely rugged with relief ranging from Clearwater Lake at an elevation of to at an unnamed peak on the northern park boundary, west of Mount Pierrway.

Siberia
Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲirʲ, a=Ru-Сибирь.ogg) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of Russia since the latter half of the 16th century, after the Russians conquered lands east of the Ural Mountains. Siberia is vast and sparsely populated, covering an area of over , but home to merely one-fifth of Russia's population. Novosibirsk, Krasnoyarsk and Omsk are the largest cities in the region. Because Siberia is a geographic and historic region and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia extends eastwards from the Ural Mountains to the Pacific Ocean, and includes most of the drainage basin of the Arctic Ocean. The river Yenisey divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of nort ...

Pleurozium Schreberi
''Pleurozium schreberi'', the red-stemmed feathermoss or Schreber's big red stem moss, is a moss with a loose growth pattern. The root name ''pleuro'' comes from the Latin for ribs, possibly describing how the parts branch from the stem. The species occurs on the floor of the boreal forests of Canada, Scandinavia and northern Russia; an example of this occurrence is within the black spruce/ feathermoss climax forest, sometimes having moderately dense overstory canopy and featuring a forest floor of feathermosses including, ''Hylocomium splendens'' and '' Ptilium crista-castrensis''.C. Michael Hogan. 2008''Black Spruce: Picea mariana'', GlobalTwitcher.com, ed.

Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-conta ...

Boreal Forest
Taiga (; rus, тайга́, p=tɐjˈɡa; relates to Mongolic and Turkic languages), generally referred to in North America as a boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest has been called the world's largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous United States. In Eurasia, it covers most of Sweden, Finland, much of Russia from Karelia in the west to the Pacific Ocean (including much of Siberia), much of Norway and Estonia, some of the Scottish Highlands, some lowland/coastal areas of Iceland, and areas of northern Kazakhstan, northern Mongolia, and northern Japan (on the island of Hokkaidō). The main tree species, depending on the length of the growing season and summer temperatures, vary across the world. The taiga of North America is mostly spruce, Scandinavian and Finnish taiga consists of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C. Washington is the 18th-largest state, with an area of , and the 13th-most populous state, with more than 7.7 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada (Saskatchewan being the other). The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds. Alberta is the fourth largest province by area at , and the fourth most populous, being home to 4,262,635 people. Alberta's capital is Edmonton, while Calgary is its largest city. The two are Alberta's largest census metropolitan areas. More than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
