Saimaa Lake
Saimaa ( , ; ) is a lake located in the Finnish Lakeland area in southeastern Finland. With a surface area of approximately , it is the largest lake in Finland, and the fourth-largest natural freshwater lake in Europe. The name Saimaa likely comes from a non-Uralic, non-Indo European substrate language. Alternatively, it has been proposed that the name may be connected to the Sami word ''sápmi''. History The lake was formed by glacial melting at the end of the Ice Age. Major towns on the lakeshore include Lappeenranta, Imatra, Savonlinna, Mikkeli, Varkaus, and Joensuu. About 6,000 years ago, ancient Lake Saimaa, estimated to cover nearly at the time, was abruptly discharged through a new outlet. The event created thousands of square kilometres of new residual wetlands. Following this event, the region saw a population maximum in the decades following only to later return to an ecological development towards old boreal conifer forests which saw a decline in population.

Freshwater Seal
Freshwater seals are pinnipeds which live in freshwater bodies. The group is paraphyletic in nature, the uniting factor being the environment in which these pinnipeds live. The vast majority of all modern seals live solely in saltwater habitats though this is likely due to the rarity of sufficiently large freshwater bodies rather than the limitation of seal biology. Baikal seals The only exclusively freshwater seal species is the Baikal seal, locally named (). The Baikal seal has inhabited Lake Baikal for roughly two million years, the closest relative to it being the Arctic ringed seal whence it has likely descended. The manner by which the baikal seal reached Lake Baikal is still not fully understood, theories include their entrance into the lake via travel up the Yenisei River or perhaps via large lakes which existed in Siberia during the Pleistocene. Ringed seals While the Baikal Seal may be the only unique species of pinniped to live in a purely freshwater environ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pusa Hispida Saimensis Ca 1956
''Pusa'' is a genus of the earless seals, within the family Phocidae. The three species of this genus were split from the genus ''Phoca'', and some sources still give ''Phoca'' as an acceptable synonym for ''Pusa''. The three species in this genus are found in Arctic and subarctic regions, as well as around the Caspian Sea. This includes these countries and regions: Russia, Finland, Scandinavia, Britain, Greenland, Canada, the United States, Iran, Azerbaijan, Kazakhstan, and Japan. Due to changing local environmental conditions, the ringed seals found in the Canadian region has varied patterns of growth. The northern Canadian ringed seals grow slowly to a larger size, while the southern seals grow quickly to a smaller size. Only the Caspian seal species of ''Pusa'' is endangered, while two subspecies of the ringed seal are vulnerable and endangered, Ladoga seal and Saimaa ringed seal The Saimaa ringed seal (''Pusa hispida saimensis'', Finnish: ''saimaannorppa'') is a subsp ...

Eutrophication
Eutrophication is a general term describing a process in which nutrients accumulate in a body of water, resulting in an increased growth of organisms that may deplete the oxygen in the water; ie. the process of too many plants growing on the surface of a river, lake, etc., often because chemicals that are used to help crops grow have been carried there by rain. Eutrophication may occur naturally or as a result of human actions. Manmade, or cultural, eutrophication occurs when sewage, Industrial wastewater treatment, industrial wastewater, fertilizer runoff, and other nutrient sources are released into the environment. Such nutrient pollution usually causes algal blooms and bacterial growth, resulting in the depletion of dissolved oxygen in water and causing substantial environmental degradation. Many policies have been introduced to combat eutrophication, including the United Nations Development Program (UNDP)'s sustainability development goals. Approaches for prevention and re ...
