Rutilus Lacustris
''Rutilus heckelii'' is a species of roach, a genus in the family Cyprinidae. This species occurs in freshened areas of Black and Azov Seas, entering the Don, Kuban, Dniepr, Dniestr and rarely Danube drainages. Newer research however suggests that ''R. heckelii'' is part of a more widely distributed species of roach, whose range extends to Siberia. The proper name of that species is ''Rutilus lacustris''.Levin, B.A., Simonov, E.P., Ermakov, O.A., Levina, M.A., Interesova, E.A., Kovalchuk, O.M., Malinina, Y.A., Mamilov, N.S., Mustafayev, N.J., Pilin, D.V., Pozdeev, I.V., Prostakov, N.I., Roubenyan, H.R., Titov, S.V. & Vekhov, D.A.

Rutilus
''Rutilus'' is a genus of fish in the family Cyprinidae found in Eurasia. This genus is a widely distributed lineage of cyprinids and ranges from West Europe to East Siberia. Species In FishBase (2022), nine species are included in the genus: * ''Rutilus caspicus'' (Yakovlev, 1870) (Caspian roach) * ''Rutilus frisii'' ( Nordmann, 1840) (Black sea roach) * ''Rutilus heckelii'' (Nordmann, 1840) * ''Rutilus kutum'' (S. N. Kamensky, 1901) (Caspian kutum) * ''Rutilus meidingeri'' ( Heckel, 1851) * ''Rutilus pigus'' ( Lacépède, 1803) (Pigo) * '' Rutilus rutilus'' (Linnaeus, 1758) (Common roach) * ''Rutilus stoumboudae Bianco & Ketmaier, 2014 * ''Rutilus virgo'' ( Heckel, 1852) (Cactus roach) In a phylogeographic study, Levin et al. (2017) argue that the Ponto-Caspian taxa including ''R. caspicus'', ''R. heckelii'' and ''R. stoumboudae'' could represent a single widespread species whose range extends to Siberia, to be named ''Rutilus lacustris'', whereas ''R. kutum'' is included in ...

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...

Azov Sea
The Sea of Azov ( Crimean Tatar: ''Azaq deñizi''; russian: Азовское море, Azovskoye more; uk, Азовське море, Azovs'ke more) is a sea in Eastern Europe connected to the Black Sea by the narrow (about ) Strait of Kerch, and is sometimes regarded as a northern extension of the Black Sea. The sea is bounded by Russia on the east, by Ukraine on the northwest and southwest. The sea is largely affected by the inflow of the Don, Kuban, and other rivers, which bring sand, silt, and shells, which in turn form numerous bays, limans, and narrow spits. Because of these deposits, the sea bottom is relatively smooth and flat with the depth gradually increasing toward the middle. Also, due to the river inflow, water in the sea has low salinity and a high amount of biomass (such as green algae) that affects the water colour. Abundant plankton result in unusually high fish productivity. The sea shores and spits are low; they are rich in vegetation and bird colonies ...

Don (river)
The Don ( rus, Дон, p=don) is the fifth-longest river in Europe. Flowing from Central Russia to the Sea of Azov in Southern Russia, it is one of Russia's largest rivers and played an important role for traders from the Byzantine Empire. Its basin is between the Dnieper basin to the west, the lower Volga basin immediately to the east, and the Oka basin (tributary of the Volga) to the north. Native to much of the basin were Slavic nomads. The Don rises in the town of Novomoskovsk southeast of Tula (in turn south of Moscow), and flows 1,870 kilometres to the Sea of Azov. The river's upper half ribbles (meanders subtly) south; however, its lower half consists of a great eastern curve, including Voronezh, making its final stretch, an estuary, run west south-west. The main city on the river is Rostov-on-Don. Its main tributary is the Seversky Donets, centred on the mid-eastern end of Ukraine, thus the other country in the overall basin. To the east of a series of three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kuban
Kuban (Russian language, Russian and Ukrainian language, Ukrainian: Кубань; ady, Пшызэ) is a historical and geographical region of Southern Russia surrounding the Kuban River, on the Black Sea between the Pontic–Caspian steppe, Don Steppe, the Volga Delta and the Caucasus, and separated from the Crimean Peninsula to the west by the Kerch Strait. Krasnodar Krai is often referred to as ''Kuban'', both officially and unofficially, although the term is not exclusive to the krai and accommodates the republics of Adygea, Karachay-Cherkessia, and parts of Stavropol Krai. Cossack settlement The Cossack settlement of Kuban and of the adjacent Black Sea region occurred gradually for over a century, and was heavily influenced by the outcomes of the conflicts between Russia and Ottoman Empire.Azarenkova et al., pp. 8ff. In the mid-18th century, the area was predominantly settled by the mountainous Adyghe people, Adyghe tribes. After the Russo-Turkish War (1768–1774 ...

Dniepr
} The Dnieper () or Dnipro (); , ; . is one of the major transboundary rivers of Europe, rising in the Valdai Hills near Smolensk, Russia, before flowing through Belarus and Ukraine to the Black Sea. It is the longest river of Ukraine and Belarus and the fourth-longest river in Europe, after the Volga, Danube, and Ural rivers. It is approximately long, with a drainage basin of . In antiquity, the river was part of the Amber Road trade routes. During the Ruin in the later 17th century, the area was contested between the Polish–Lithuanian Commonwealth and Russia, dividing Ukraine into areas described by its right and left banks. During the Soviet period, the river became noted for its major hydroelectric dams and large reservoirs. The 1986 Chernobyl disaster occurred on the Pripyat, immediately above that tributary's confluence with the Dnieper. The Dnieper is an important navigable waterway for the economy of Ukraine and is connected by the Dnieper–Bug Canal to other w ...

Dniestr
The Dniester, ; rus, Дне́стр, links=1, Dnéstr, ˈdⁿʲestr; ro, Nistru; grc, Τύρᾱς, Tyrās, ; la, Tyrās, la, Danaster, label=none, ) ( ,) is a transboundary river in Eastern Europe. It runs first through Ukraine and then through Moldova (from which it more or less separates the breakaway territory of Transnistria), finally discharging into the Black Sea on Ukrainian territory again. Names The name ''Dniester'' derives from Sarmatian ''dānu nazdya'' "the close river." (The Dnieper, also of Sarmatian origin, derives from the opposite meaning, "the river on the far side".) Alternatively, according to Vasily Abaev ''Dniester'' would be a blend of Scythian ''dānu'' "river" and Thracian ''Ister'', the previous name of the river, literally Dān-Ister (River Ister). The Ancient Greek name of Dniester, ''Tyras'' (Τύρας), is from Scythian ''tūra'', meaning "rapid." The names of the Don and Danube are also from the same Indo-Iranian word ''*dānu'' "ri ...

Danube
The Danube ( ; ) is a river that was once a long-standing frontier of the Roman Empire and today connects 10 European countries, running through their territories or being a border. Originating in Germany, the Danube flows southeast for , passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine before draining into the Black Sea. Its drainage basin extends into nine more countries. The largest cities on the river are Vienna, Budapest, Belgrade and Bratislava, all of which are the capitals of their respective countries; the Danube passes through four capital cities, more than any other river in the world. Five more capital cities lie in the Danube's basin: Bucharest, Sofia, Zagreb, Ljubljana and Sarajevo. The fourth-largest city in its basin is Munich, the capital of Bavaria, standing on the Isar River. The Danube is the second-longest river in Europe, after the Volga in Russia. It flows through much of Central and Sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...
