Catostomus Catostomus Catostomus
The longnose sucker (''Catostomus catostomus'') is a species of cypriniform freshwater fish in the family Catostomidae. It is native to North America from the northern United States to the top of the continent. It is also found in Russia in rivers of eastern Siberia, and thus one of only two species of sucker native to Asia (the other is the Chinese '' Myxocyprinus asiaticus''). Description The body of the longnose sucker is long and round with dark olive or grey sides and top and a light underside. They are up to in total length and weigh up to . Longnose suckers are easily confused with white suckers (''Catostomus commersoni''), which appear very similar. However, longnose suckers can be distinguished by their comparatively finer scales. Distribution and ecology The longnose sucker inhabits cold, clear waters, including lakes, pools, rivers and streams, and occasionally also brackish waters. In North America, it ranges north from the Columbia, Delaware, Missouri and M ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Johann Reinhold Forster
Johann Reinhold Forster (22 October 1729 – 9 December 1798) was a German Continental Reformed church, Reformed (Calvinist) pastor and natural history, naturalist of partially Scottish descent who made contributions to the early ornithology of Europe and North America. He is best known as the naturalist on James Cook's Second voyage of James Cook, second Pacific voyage, where he was accompanied by his son Georg Forster. These expeditions promoted the career of Johann Reinhold Forster and the findings became the bedrock of colonial professionalism and helped set the stage for the future development of anthropology and ethnology. They also laid the framework for general concern about the impact that alteration of the physical environment for European economic expansion would have on exotic societies. Biography Forster's family originated in the Lord Forrester, Lords Forrester in Scotland from where his great-grandfather had emigrated after losing most of his property during the ...

Aquatic Plants
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecologi ...

Kolyma
Kolyma (russian: Колыма́, ) is a region located in the Russian Far East. It is bounded to the north by the East Siberian Sea and the Arctic Ocean, and by the Sea of Okhotsk to the south. The region gets its name from the Kolyma River and mountain system, parts of which were not accurately mapped by Russian surveyors until 1926. Today the region consists roughly of the Chukotka Autonomous Okrug and the Magadan Oblast. The area, part of which is within the Arctic Circle, has a subarctic climate with very cold winters lasting up to six months of the year. Permafrost and tundra cover a large part of the region. Average winter temperatures range from (even lower in the interior), and average summer temperatures, from . There are rich reserves of gold, silver, tin, tungsten, mercury, copper, antimony, coal, oil, and peat. Twenty-nine zones of possible oil and gas accumulation have been identified in the Sea of Okhotsk shelf. Total reserves are estimated at 3.5 billion tons ...
