Rogen Nature Reserve
Rogen Nature Reserve ( sv, Rogens naturreservat) is a nature reserve in Jämtland County in Sweden. It is part of the EU-wide Natura 2000-network. The nature reserve is centred on Lake Rogen and is part of a wider network of nature protection areas that extend also on the other side of the border with Norway. The landscape is distinctly characterised by Rogen moraine, a type of moraine named after the area. It consists of long, sinuous low hills interspersed with long lakes. In addition, large erratic boulders are spread over the land. In all directions, mountain tops — parts of the Scandinavian Mountains — rise to about . The highest peak in the area is ''Brattriet'' with an altitude of . The landscape was formed during the last Ice age, and has been described as "labyrinthine". Fauna The nature reserve has a rich fauna. European otter, Eurasian lynx, brown bear and wolverine all inhabit the nature reserve. Birds such as golden eagle, black-throated loon, rough-legged buzza ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jämtland County
Jämtland County ( sv, Jämtlands län, ) is a county or '' län'' in the middle of Sweden consisting of the provinces of Jämtland and Härjedalen, along with minor parts of Hälsingland and Ångermanland, plus two small uninhabited strips of Lapland and Dalarna. Jämtland County constitutes 12 percent of Sweden's total area, and is the third largest county in the country. The county capital is Östersund and the county governor, appointed by the Swedish government, is Jöran Hägglund, who leads the administrative board. Jämtland County borders the counties of Dalarna, Gävleborg, Västernorrland, and Västerbotten. It also shares a border with the Norwegian county of Trøndelag. The county was established in 1810 and its foundation has both domestic and foreign causes. Upon formation it only consisted of the provinces of Jämtland and Härjedalen, which is why the coat of arms is a shield parted per fess with their provincial arms. Being sparsely populated, the land ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-throated Loon
The black-throated loon (''Gavia arctica''), also known as the Arctic loon and the black-throated diver, is a migratory aquatic bird found in the northern hemisphere, primarily breeding in freshwater lakes in northern Europe and Asia. It winters along sheltered, ice-free coasts of the north-east Atlantic Ocean and the eastern and western Pacific Ocean. This loon was first described by Carl Linnaeus in 1758. It has two subspecies. It was previously considered to be the same species as the Pacific loon, of which it is traditionally considered to be a sister species, although this is debated. In a study that used mitochondrial and nuclear intron DNA, the black-throated loon was found to be sister to a clade consisting of the Pacific loon and two sister species, the common loon and the yellow-billed loon. The black-throated loon measures about in length and can weigh anywhere from . In breeding plumage, the adult of the nominate subspecies has mostly black upperparts, with the ex ...

Scots Pine
''Pinus sylvestris'', the Scots pine (UK), Scotch pine (US) or Baltic pine, is a species of tree in the pine family Pinaceae that is native to Eurasia. It can readily be identified by its combination of fairly short, blue-green leaves and orange-red bark. Description ''Pinus sylvestris'' is an evergreen coniferous tree growing up to in height and in trunk diameter when mature, exceptionally over tall and in trunk diameter on very productive sites. The tallest on record is a tree over 210 years old tree growing in Estonia which stands at . The lifespan is normally 150–300 years, with the oldest recorded specimens in Lapland, Northern Finland over 760 years. The bark is thick, flaky and orange-red when young to scaly and gray-brown in maturity, sometimes retaining the former on the upper portion.Trees for LifeSpecies profile: Scots pine/ref> The habit of the mature tree is distinctive due to its long, bare and straight trunk topped by a rounded or flat-topped mass of ...

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] |
Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk.

Muskox
The muskox (''Ovibos moschatus'', in Latin "musky sheep-ox"), also spelled musk ox and musk-ox, plural muskoxen or musk oxen (in iu, ᐅᒥᖕᒪᒃ, umingmak; in Woods Cree: ), is a hoofed mammal of the family Bovidae. Native to the Arctic, it is noted for its thick coat and for the strong odor emitted by males during the seasonal rut, from which its name derives. This musky odor has the effect of attracting females during mating season. Its Inuktitut name "umingmak" translates to "the bearded one". Its Woods Cree names "mâthi-môs" and "mâthi-mostos" translate to "ugly moose" and "ugly bison", respectively. Muskoxen primarily live in Greenland and the Canadian Arctic of the Northwest Territories and Nunavut, with reintroduced populations in the American state of Alaska, the Canadian territory of Yukon, and Siberia, and an introduced population in Norway, part of which emigrated to Sweden, where a small population now lives.

Northern Pike
The northern pike (''Esox lucius'') is a species of carnivorous fish of the genus '' Esox'' (the pikes). They are typical of brackish and fresh waters of the Northern Hemisphere (''i.e.'' holarctic in distribution). They are known simply as a pike in Britain, Ireland, and most of Eastern Europe, Canada and the United States. Pike can grow to a relatively large size: the average length is about , with maximum recorded lengths of up to and published weights of . The IGFA currently recognizes a pike caught by Lothar Louis on Greffern Lake, Germany, on 16 October 1986, as the all-tackle world-record northern pike. Northern pike grow to larger sizes in Eurasia than in North America, and typically grow to larger sizes in coastal than inland regions of Eurasia. Etymology The northern pike gets its common name from its resemblance to the pole-weapon known as the pike (from the Middle English for 'pointed'). Various other unofficial trivial names are common pike, Lakes pike, great n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perch
Perch is a common name for fish of the genus ''Perca'', freshwater gamefish belonging to the family Percidae. The perch, of which three species occur in different geographical areas, lend their name to a large order of vertebrates: the Perciformes, from the el, πέρκη (), simply meaning perch, and the Latin ''forma'' meaning shape. Many species of freshwater gamefish more or less resemble perch, but belong to different genera. In fact, the exclusively saltwater-dwelling red drum is often referred to as a red perch, though by definition perch are freshwater fish. Though many fish are referred to as perch as a common name, to be considered a true perch, the fish must be of the family Percidae. The type species for this genus is the European perch, ''P. fluviatilis''. Species Most authorities recognize three species within the perch genus: * The European perch (''P. fluviatilis'') is primarily found in Europe, but a few can also be found in South Africa, and even as far ea ...

Salvelinus
''Salvelinus'' is a genus of Salmonidae, salmonid fish often called char or charr; some species are called "trout". ''Salvelinus'' is a member of the subfamily Salmoninae within the family Salmonidae. The genus has a northern circumpolar distribution, and most of its members are typically cold-water fish that primarily inhabit fresh waters. Many species also migrate to the sea. Most char may be identified by light-cream, pink, or red spots over a darker body. Scales tend to be small, with 115-200 along the lateral line. The pectoral, pelvic, anal, and the lower aspect of caudal fins are trimmed in snow white or cream leading edges. Many members of this genus are popular sport fish, and a few, such as lake trout (''S. namaycush'') and arctic char (''S. alpinus'') are objects of commercial fisheries and/or aquaculture. Occasionally, such fish escape and become invasive species. Deepwater char are small species of char living below 80 m in the deep areas of certain lakes. They are ...

Thymallus Thymallus
''Thymallus thymallus'', the grayling or European grayling, is a species of freshwater fish in the salmon family Salmonidae. It is the only species of the genus ''Thymallus'' (the graylings) native to Europe, where it is widespread from the United Kingdom and France to the Ural Mountains in Russia, and Balkans on the south-east, but does not occur in the southern parts of the continent. It was introduced to Morocco in 1948, but it does not appear to have become established there. Description The grayling grows to a maximum recorded length of and a maximum recorded weight of . Of typical ''Thymallus'' appearance, the grayling proper is distinguished from the similar Arctic grayling (''T. arcticus arcticus'') by the presence of 5–8 dorsal and 3–4 anal spines, which are absent in the other species; ''T. thymallus'' also has a smaller number of soft rays in these fins. Individuals of the species have been recorded as reaching an age of 14 years. The grayling prefers cold, clean, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burbot
The burbot (''Lota lota'') is the only gadiform (cod-like) freshwater fish Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 1.05%. These environments differ from marine conditions in many ways, especially the difference in levels of .... It is also known as bubbot, mariah, loche, cusk, freshwater cod, freshwater ling, freshwater cusk, the lawyer, coney-fish, lingcod, and eelpout. The species is closely related to the marine common ling and the cusk (fish), cusk. It is the monotypic, only member of the genus ''Lota''. For some time of the year, the burbot lives under ice, and it requires frigid temperatures to breed. Etymology The name burbot comes from the Latin word ''barba'', meaning beard, referring to its single chin whisker, or barbel (anatomy), barbel. Its generic and specific names, ''Lota lota'', comes from the old French ''lotte'' fish, which is also named "barbot" in Old French. ...

Brown Trout
The brown trout (''Salmo trutta'') is a European species of salmonid fish that has been widely introduced into suitable environments globally. It includes purely freshwater populations, referred to as the riverine ecotype, ''Salmo trutta'' morpha ''fario'', a lacustrine ecotype, ''S. trutta'' morpha ''lacustris'', also called the lake trout, and anadromous forms known as the sea trout, ''S. trutta'' morpha ''trutta''. The latter migrates to the oceans for much of its life and returns to fresh water only to spawn. Sea trout in Ireland and Britain have many regional names: sewin in Wales, finnock in Scotland, peal in the West Country, mort in North West England, and white trout in Ireland. The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although evidence indicates some stocks spawn on wind-swept shorelines of lakes. ''S. trutta'' morpha ''fario'' forms stream-resident populations, typically in alpine stre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
