Kola Peninsula Tundra
The Kola Peninsula tundra ecoregion (WWF ID: PA1106) is an ecoregion that covers the northeastern half of the Kola Peninsula, along the coast of the White Sea, a marginal sea of the Arctic Ocean. The maritime effects of the White Sea create a milder climate than would be expected for a region of this latitude. It is in the Palearctic realm, and the tundra biome. It has an area of . Location and description The northernmost segments of this ecoregion are on the northern coast of Fennoscandia, facing the Barents Sea. The more southerly regions are the northeastern edge of the Kola Peninsula, facing the White Sea. Climate The region has a Humid continental climate - cool summer subtype (Koppen classification Dfc). This climate is characterized by high variation in temperature, both daily and seasonally; with long, cold winters and short, cool summers with no averaging over . Mean precipitation is about 512 mm/year. The mean temperature at the center of the ecoregion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palearctic Realm
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/Afrotropic, Indian/Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wallace ad ...

Rubus Chamaemorus
''Rubus chamaemorus'' is a species of flowering plant in the rose family Rosaceae, native to cool temperate regions, alpine and arctic tundra and boreal forest. This herbaceous perennial produces amber-colored edible fruit similar to the blackberry. English common names include cloudberry, nordic berry, bakeapple (in Newfoundland and Labrador), knotberry and knoutberry (in England), aqpik or low-bush salmonberry (in Alaska – not to be confused with salmonberry, ''Rubus spectabilis''), and averin or evron (in Scotland). Description Unlike most ''Rubus'' species, the cloudberry is dioecious, and fruit production by a female plant requires pollination from a male plant. The cloudberry grows to high. The leaves alternate between having 5 and 7 soft, handlike lobes on straight, branchless stalks. After pollination, the white (sometimes reddish-tipped) flowers form raspberry-sized aggregate fruits which are more plentiful in wooded rather than sun-exposed habitats. Consisting of ...

Geography Of Finnmark
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ecoregions Of Norway
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varangerhalvøya National Park
Varangerhalvøya National Park ( no, Varangerhalvøya nasjonalpark) lies on the Varanger Peninsula in Troms og Finnmark county, Norway. It is located in the municipalities of Båtsfjord, Nesseby, Vadsø, and Vardø, in the northeasternmost part of Norway. The peninsula was earlier the largest area within the Arctic climate zone in mainland Norway, but with the 1991-2020 normals, much of the area is boreal rather than arctic. Much of the area is still alpine tundra. Flora and fauna Since species from the Arctic, eastern Siberia, and more southerly areas all occur together on the Varanger Peninsula, the plant life is distinctive. The small deciduous woodlands in the area are among the northernmost in the world. Lime-rich bedrock and soil in the north supports rich pockets containing rare species like ''Papaver dahlianum'' (a poppy), field fleawort, Svalbard snow cinquefoil , and '' Arenaria pseudofrigida'' (a sandwort). The peninsula still has a complete alpine ecosystem with re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kandalaksha Nature Reserve
Kandalaksha Nature Reserve (russian: Кандалакшский заповедник) (also Kandalakshsky) is a Russian 'zapovednik' (strict ecological reserve) on the south shore of Kandalaksha Bay in the Murmansk and Karelia regions on the opening to the White Sea. The reserve also includes two small sectors on the northern coast of the Kola peninsula on the Barents Sea; notably, the warm Atlantic current causes the northern sectors on the Barents Sea to be warmer than the more southerly White Sea sectors. Over 550 islands are covered in the boundaries of the reserve. It is one of the oldest nature reserves in Russia, created in 1932 to protect the marine habitats and waterfowl of the region, particularly the eider. The reserve is situated in the Kandalakshsky District, Kolsky District, and Lovozersky District of Murmansk Oblast. The nearest city, Kandalaksha, is at the northwest entrance to the Kandalaksha Gulf, about 5 km from the nearest point in the reserve. Since 1976, th ...

Reindeer
Reindeer (in North American English, known as caribou if wild and ''reindeer'' if domesticated) are deer in the genus ''Rangifer''. For the last few decades, reindeer were assigned to one species, ''Rangifer tarandus'', with about 10 subspecies. A 2022 revision of the genus elevated five of the subspecies to species (see Taxonomy below). They have a circumpolar distribution and are native to the Arctic, sub-Arctic, tundra, boreal forest, and mountainous regions of northern Europe, Siberia, and North America. Reindeer occur in both migratory and sedentary populations, and their herd sizes vary greatly in different regions. The tundra subspecies are adapted for extreme cold, and some are adapted for long-distance migration. Reindeer vary greatly in size and color from the smallest species, the Svalbard reindeer (''R. t. platyrhynchus''), to the largest subspecies, Osborn's caribou (''R. t. osborni''). Although reindeer are quite numerous, some species and subspecies are in d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betula Nana
''Betula nana'', the dwarf birch, is a species of birch in the family Betulaceae, found mainly in the tundra of the Arctic region. Description It is a monoecious, deciduous shrub growing up to high. The bark is non-peeling and shiny red-copper colored. The leaves are rounded, diameter, with a bluntly toothed margin. The leaves are a darker green on their upper surface. Leaf growth occurs after snow melt and become red in autumn. The wind-pollinated fruiting catkins are erect, long and broad. Distribution ''Betula nana'' is native to arctic and cool temperate regions of Greenland, Iceland, northern Europe, northern Asia and northern North America and it will grow in a variety of conditions. Outside of far northern areas, it is usually found growing only in mountains above , up to in Great Britain and in the Alps. Its northern range limit is on Svalbard, where it is confined to favourable sites. In the UK ''Betula nana'' is at its southern range limit, with many populations ...

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-contained g ...
