Dniester
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 ...

Fish Of The Black Sea
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

Benthophilus
The tadpole-gobies (''Benthophilus''), also called pugolovkas (which means "tadpole" in Ukrainian), are a genus of Ponto-Caspian fishes in the family Gobiidae. They are distributed in the fresh and brackish waters of basins of the Black Sea, Caspian Sea and the Sea of Azov, up to salinities of about 20 ‰. They typically live in habitats such as the deep waters of the Caspian (salinity about 13 ‰) and in the deltas, estuaries and coastal waters of the Ponto-Caspian. Tadpole-gobies are small fish, never larger than 15 cm, and usually smaller. Their life span is about one year. After spawning they die. Species There are currently 20 recognized species in this genus:Boldyrev V.S., Bogutskaya N.G. (2007) Revision of the tadpole-gobies of the genus ''Benthophilus'' (Teleostei: Gobiidae). Ichthyol.

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.

Gobiidae
Gobiidae or gobies is a family of bony fish in the order Gobiiformes, one of the largest fish families comprising more than 2,000 species in more than 200 genera. Most of gobiid fish are relatively small, typically less than in length, and the family includes some of the smallest vertebrates in the world, such as '' Trimmatom nanus'' and ''Pandaka pygmaea'', ''Trimmatom nanus'' are under long when fully grown, then ''Pandaka pygmaea'' standard length are , maximum known standard length are . Some large gobies can reach over in length, but that is exceptional. Generally, they are benthic or bottom-dwellers. Although few are important as food fish for humans, they are of great significance as prey species for other commercially important fish such as cod, haddock, sea bass and flatfish. Several gobiids are also of interest as aquarium fish, such as the dartfish of the genus ''Ptereleotris''. Phylogenetic relationships of gobiids have been studied using molecular data. Descript ...

Dnieper
} 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 ...

Tighina
Bender (, Moldovan Cyrillic: Бендер) or Bendery (russian: Бендеры, , uk, Бендери), also known as Tighina ( ro, Tighina), is a city within the internationally recognized borders of Moldova under ''de facto'' control of the unrecognized Pridnestrovian Moldavian Republic (Transnistria) (PMR) since 1992. It is located on the western bank of the river Dniester in the Romanian historical region of Bessarabia. Together with its suburb Proteagailovca, the city forms a municipality, which is separate from Transnistria (as an administrative unit of Moldova) according to Moldovan law. Bender is located in the buffer zone established at the end of the 1992 War of Transnistria. While the Joint Control Commission has overriding powers in the city, Transnistria has ''de facto'' administrative control. The fortress of Tighina was one of the important historic fortresses of the Principality of Moldova until 1812. Name First mentioned in 1408 as ''Tyagyanyakyacha'' (Тя ...

Iron Gate (Danube)
The Iron Gates ( ro, Porțile de Fier; sr, / or / ; Hungarian: ''Vaskapu-szoros'') is a gorge on the river Danube. It forms part of the boundary between Serbia (to the south) and Romania (north). In the broad sense it encompasses a route of ; in the narrow sense it only encompasses the last barrier on this route, just beyond the Romanian city of Orșova, that contains two hydroelectric dams, with two power stations, Iron Gate I Hydroelectric Power Station and Iron Gate II Hydroelectric Power Station. At this point in the Danube, the river separates the southern Carpathian Mountains from the northwestern foothills of the Balkan Mountains. The Romanian side of the gorge constitutes the Iron Gates Natural Park, whereas the Serbian part constitutes the Đerdap National Park. A wider protected area on the Serbian side was declared the UNESCO global geopark in July 2020. Archaeologists have named the Iron Gates mesolithic culture, of the central Danube region circa 13,000 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
