Alburnus Derjugini
The Georgian shemaya (''Alburnus derjugini'') is a species of ray-finned fish belonging to the family Leuciscidae. It is found in eastern Black Sea tributaries, from south of the Caucasus in Russia and Georgia, south to the Çoruh River in eastern Anatolia, Turkey and west to the Sakarya River. The species name commemorates the collector Konstantin Deryugin Konstantin Mikhailovich Deryugin (: 10 February 1878 – 27 December 1938) was Russian Empire and Soviet oceanographer and marine biologist.

Lev Berg
Lev Semyonovich Berg, also known as Leo S. Berg (; 14 March 1876 – 24 December 1950) was a leading Russian geographer, biologist and ichthyologist who served as President of the Soviet Geographical Society between 1940 and 1950. He is known for his own evolutionary theory, nomogenesis (a form of orthogenesis incorporating mutationism) as opposed to the theories of Darwin and Lamarck. Life Lev Berg was born in Bessarabia in a Jewish family, the son of Simon Gregoryevich Berg, a notary, and Klara Lvovna Bernstein-Kogan. He graduated from the Second Kishinev Gymnasium in 1894. Like some of his relatives, Berg converted to Christianity in order to pursue his studies at Moscow State University. At Moscow University, Berg studied hydrobiology and geography. He later studied ichthyology and in 1928 was awarded he was also a member of the Russian Academy of Sciences. Lev Berg graduated from the Moscow State University in 1898. Between 1903 and 1914, he worked in the Museum of Z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class (biology), class of Osteichthyes, bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fish fin, fins made of webbings of skin supported by radially extended thin bony spine (zoology), spines called ''lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister taxon, sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation (anatomy), articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they domi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Leuciscidae
Leuciscidae is a family of freshwater ray-finned fishes, formerly classified as a subfamily of the Cyprinidae, which contains the true minnows. Members of the Old World (OW) clade of minnows within this subfamily are known as European minnows. As the name suggests, most members of the OW clade are found in Eurasia, aside from the golden shiner (''Notemigonus crysoleucas''), which is found in eastern North America North America is a continent in the Northern Hemisphere, Northern and Western Hemisphere, Western hemispheres. North America is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South Ameri .... According to ancestral area reconstruction, the subfamily Leuciscinae is thought to have originated in Europe before becoming widely distributed in parts of Europe, Asia and North America. Evidence for the dispersal of this subfamily can be marked by biogeographical scenarios/observations, geomorphological changes, ...

Black Sea
The Black Sea is a marginal sea, marginal Mediterranean sea (oceanography), mediterranean sea 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 (country), Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is Inflow (hydrology), supplied by major rivers, principally the Danube, Dnieper and Dniester. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea, not including the Sea of Azov, covers , 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 ...

Caucasus
The Caucasus () or Caucasia (), is a region spanning Eastern Europe and Western Asia.

Mount Elbrus, Europe's highest mountain, is situated in the Western Caucasus area of Russia. On the southern side, the Lesser Caucasus includes the Javakheti Plateau and the Armenian highlands. The Caucasus is divided into the North Caucasus and South Caucasus, although the Western Caucasus also exists as a distinct geographic space within the North Caucasus. The Greater Caucasus mountain range in the north is mostly shared by Russia and Georgia as well as the northernmost parts of Azerbaijan.

Çoruh River
The Chorokh ( ka, ჭოროხი ''Ch'orokhi'' , , ''Chorokh'', , , ''Akampsis'') is a river that rises in the Mescit Mountains in north-eastern Turkey, flows through the cities of Bayburt, İspir, Yusufeli, and Artvin, along the Kelkit River, Kelkit-Çoruh Fault, before flowing into Georgia (country), Georgia, where it reaches the Black Sea just south of Batumi and a few kilometers north of the Turkish-Georgian border. In Arrian's ''Periplus Ponti Euxini'', it is called the ''Acampsis'' (); Pliny the Elder, Pliny may have confused it with the ''Bathys''. Procopius writes that it was called Acampsis because it was impossible to force a way through it after it has entered the sea, since it discharges its stream with such force and swiftness, causing a great disturbance of the water before it, that it goes out for a very great distance into the sea and makes it impossible to coast along at that point. In English, it was formerly known as the Boas, the Churuk, or the Chorokh. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatolia
Anatolia (), also known as Asia Minor, is a peninsula in West Asia that makes up the majority of the land area of Turkey.

Sakarya River
The Sakarya (; ; ; ) is the third longest river in Turkey. It runs through the region known in ancient times as Phrygia. It was considered one of the principal rivers of Asia Minor (Anatolia) in Greek classical antiquity, and is mentioned in the ''Iliad'' and in ''Theogony''. Its name appears in different forms as Sagraphos, Sangaris, or Sagaris. In ''Geographica'', Strabo wrote during classical antiquity that the river had its sources on Mount Adoreus, near the town of Sangia in Phrygia, not far from the border with Galatia, and flowed in a very tortuous course: first in an eastern direction, then toward the north, then in a northwesterly direction and finally to the north through Bithynia into the Euxine (Black Sea). Pseudo-Plutarch wrote that a man named Sagaris often disdained the mysteries of the Mother of the Gods, frequently deriding her priests. She struck him with madness, and he flung himself into the river Xerobates, which from then on was called Sagaris. Part of ...
