Ladoga Seal
The Ladoga ringed seal (russian: Ладожская нерпа; ''Pusa hispida ladogensis''), is a freshwater subspecies of the ringed seal (''Pusa hispida'') which are found entirely in Lake Ladoga in northwestern Russia. The subspecies evolved during the last ice age, about 11,000 years ago. As the glaciers retreated and water levels changed, the Baltic ringed seal (including Ladoga seals) was trapped in freshwater lakes and separated from the Arctic ringed seal. It is related to the even smaller population of Saimaa ringed seals in Lake Saimaa, a lake that flows into Ladoga through the Vuoksi River. Appearance The adult Ladoga seal grows to about 150 cm in length and weighs approximately 60–70 kg. Pups are approximately 50–60 cm at birth and weigh approximately 4–5 kg. There are four variations of coats.Popov, L. "Ladoga Seal." ''Mammals in the Seas, volume II: pinniped species summaries and report on sirenians'' (FAO Fisheries Series) No. 5, Vo ...

Oscar Frithiof Nordquist
Oscar Frithiof Nordqvist Ph.D. (19 May 1858 – 1925) was a Finnish hydrographer. At age twelve he was one of the first students at the art school of the Finnish art association. While serving as a Lieutenant in the military of the Grand Duchy of Finland, he accompanied Adolf Erik Nordenskiöld on S.S. Vega through the Northeast Passage in 1879, acting as the expedition's interpreter of Russian. In 1887 he was in charge of a hydrographical expedition to the Gulf of Bothnia, marking the start of hydrographical work in Finland. - detailing Nordqvist's role in the formation of ICES In 1901 he headed the |
Mammals Of Russia
This is a list of the mammal species recorded in Russia. There are 266 mammal species in Russia, of which five are critically endangered, thirteen are endangered, twenty-six are vulnerable, and six are near threatened. One of the species listed for Russia is extinct and one can no longer be found in the wild. All the mammals of Russia are in the subclass Theria and infraclass Eutheria, being all Placentalia, placental.

Pinniped
Pinnipeds (pronounced ), commonly known as seals, are a widely range (biology), distributed and diverse clade of carnivorous, fin-footed, semiaquatic, mostly marine mammal, marine mammals. They comprise the extant taxon, extant family (biology), families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals). There are 34 extant species of pinnipeds, and more than 50 extinct species have been described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular phylogenetics, molecular evidence supports them as a monophyletic lineage (descended from one ancestral line). Pinnipeds belong to the order Carnivora; their closest living relatives are Musteloidea, musteloids (Mustelidae, weasels, Procyonidae, raccoons, skunks, and red pandas), having diverged about 50 million years ago. Seals range in size from the and Baikal sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Data Book Of The Russian Federation
''Red Data Book of the Russian Federation'' (''RDBRF''), also known as ''Red Book'' (russian: Красная книга) or ''Russian Red Data Book'', is a state document established for documenting rare and endangered species of animals, plants and fungi, as well as some local subspecies (such as the Ladoga seal) that exist within the territory of the Russian Federation and its continental shelf and marine economic zone. The book has been adopted by Russia to enact a common agreement on rare and endangered species protection. Conservation The book provides a central information source in organizing studies and monitoring programs on rare and endangered species and their habitats. History The first Russian ''Red Data Book'' was based upon research conducted between 1961 and 1964 by a number of Soviet biologists. It represented the Soviet part of the IUCN Red List (hence the name). At that time it was just the Soviet Union's first organized list of endangered species, not a leg ...

Industrialization
Industrialisation ( alternatively spelled industrialization) is the period of social and economic change that transforms a human group from an agrarian society into an industrial society. This involves an extensive re-organisation of an economy for the purpose of manufacturing. Historically industrialization is associated with increase of polluting industries heavily dependent on fossil fuels. With the increasing focus on sustainable development and green industrial policy practices, industrialization increasingly includes technological leapfrogging, with direct investment in more advanced, cleaner technologies. The reorganization of the economy has many unintended consequences both economically and socially. As industrial workers' incomes rise, markets for consumer goods and services of all kinds tend to expand and provide a further stimulus to industrial investment and economic growth. Moreover, family structures tend to shift as extended families tend to no longer liv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poaching
Poaching has been defined as the illegal hunting or capturing of wild animals, usually associated with land use rights. Poaching was once performed by impoverished peasants for subsistence purposes and to supplement meager diets. It was set against the hunting privileges of nobility and territorial rulers. Since the 1980s, the term "poaching" has also been used to refer to the illegal harvesting of wild plant species. In agricultural terms, the term 'poaching' is also applied to the loss of soils or grass by the damaging action of feet of livestock, which can affect availability of productive land, water pollution through increased runoff and welfare issues for cattle. Stealing livestock as in cattle raiding classifies as theft, not as poaching. The United Nations' Sustainable Development Goal 15 enshrines the sustainable use of all wildlife. It targets the taking of action on dealing with poaching and trafficking of protected species of flora and fauna to ensure their avail ...

Names Given To Animals Young
In the English language, animals have different names depending on whether they are male, female, young, domesticated, or in groups. The best-known source of many English words used for collective groupings of animals is '' The Book of Saint Albans'', an essay on hunting published in 1486 and attributed to Juliana Berners. Most terms used here may be found in common dictionaries and general information web sites. Generic terms The terms in this table apply to many or all taxons in a particular biological family, class, or clade. Terms by species or taxon Usage of collective nouns '' Merriam-Webster'' writes that most terms of venery fell out of use in the 16th century, including a "murder" for crows. It goes on to say that some of the terms in '' The Book of Saint Albans'' were "rather fanciful", explaining that the book extended collective nouns to people of specific professions, such as a "poverty" of pipers. It concludes that for lexicographers, many of these don't ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Seal
The freshwater seals are seals which live in freshwater bodies. The only exclusively freshwater seal species is the Baikal seal, locally named (). The others are the subspecies or colonies of regular saltwater seals. These include two subspecies of ringed seal: the Ladoga seal and the Saimaa ringed seal. Common seals (harbor seals) are known to enter estuaries and freshwater rivers in pursuit of their prey. Colonies of common seals live in some lakes, such as seals of Iliamna Lake, Alaska, trapped there a long time ago. There is also a subspecies called the Ungava seal (''Phoca vitulina mellonae'') that comprises less than 300 individuals landlocked in the fresh water of Lacs des Loups Marins, Petit Lac de Loups Marins, and Lac Bourdel in northern Quebec. California sea lions can also live in fresh water for periods of time, such as near Bonneville Dam, nearly up the Columbia River. In 2004, a healthy sea lion was found sitting on a road in Merced County, California, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vuoksi River
The Vuoksi (russian: Вуокса, historically: "Uzerva"; fi, Vuoksi; sv, Vuoksen) is a river running through the northernmost part of the Karelian Isthmus from Lake Saimaa in southeastern Finland to Lake Ladoga in northwestern Russia. The river enters Lake Ladoga in three branches, an older main northern branch at Priozersk (Käkisalmi), a smaller branch a few kilometers to the north of it, and a new southern branch entering further southeast as Burnaya River (Finnish: Taipaleenjoki), which has become the main stream in terms of water discharge. Since 1857, the old northern distributaries drain only the lower reaches of the Vuoksi basin and are not fed by Lake Saimaa. The northern and southern branches actually belong to two separate river systems, which at times get isolated from each other in dry seasons. The descent between Lake Saimaa and Lake Ladoga is . The entire run of the river is via the Priozersk branch, or via the Taipale (Burnaya) branch. It has a drainage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
