Rutilus Atropatenus
''Rutilus atropatenus'', also known as the Azerbaijani spring roach or Shirvan roachling, is a species of freshwater ray-finned fish belonging to the family Leuciscidae, which includes the daces, Eurasian minnows and related species. This species is endemic to Azerbaijan.Kuljanishvili, T., G. Epitashvili, J. Freyhof, B. Japoshvili, L. Kalous, B. Levin, N. Mustafayev, S. Ibrahimov, S. Pipoyan and L.

Freshwater
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include non-salty mineral-rich waters, such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is n ... [...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, ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Kura (Caspian Sea)
The Kura, also known in Georgian as Mtkvari ( ), is an east-flowing transboundary river south of the Greater Caucasus Mountains which drains the southern slopes of the Greater Caucasus east into the Caspian Sea. It also drains the north side of the Lesser Caucasus, while its main tributary, the Aras, drains the south side of those mountains. Starting in northeastern Turkey, the Kura flows through to Georgia, then into Azerbaijan, where it receives the Aras as a right tributary, and finally enters the Caspian Sea. The total length of the river is . People have inhabited the Caucasus region for thousands of years and first established agriculture in the Kura Valley over 4,500 years ago. Large, complex civilizations eventually grew on the river, but by 1200 CE most were reduced to ruin by natural disasters and foreign invaders. The increasing human use, and eventual damage, of the watershed's forests and grasslands, contributed to a rising intensity of floods through the 20th cen ...

Azerbaijan
Azerbaijan, officially the Republic of Azerbaijan, is a Boundaries between the continents, transcontinental and landlocked country at the boundary of West Asia and Eastern Europe. It is a part of the South Caucasus region and is bounded by the Caspian Sea to the east, Russia's republic of Dagestan to the north, Georgia (country), Georgia to the northwest, Armenia and Turkey to the west, and Iran to the south. Baku is the capital and largest city. The territory of what is now Azerbaijan was ruled first by Caucasian Albania and later by various Persian empires. Until the 19th century, it remained part of Qajar Iran, but the Russo-Persian wars of Russo-Persian War (1804–1813), 1804–1813 and Russo-Persian War (1826–1828), 1826–1828 forced the Qajar Empire to cede its Caucasian territories to the Russian Empire; the treaties of Treaty of Gulistan, Gulistan in 1813 and Treaty of Turkmenchay, Turkmenchay in 1828 defined the border between Russia and Iran.

Rutilus
''Rutilus'', commonly known as roaches, is a genus of freshwater ray-finned fish belonging to the family Leuciscidae, which includes the daces, Eurasian minnows and related fishes. This genus is a widely distributed lineage of leuciscids and ranges from West Europe to East Siberia. Taxonomy ''Rutilus'' was first proposed as a genus in 1820 by the French polymath Constantine Samuel Rafinesque with ''Cyprinus rutilus'' designated as the type species but also the type species by absolute tautonymy. ''Cyprinus rutilus'' was first formally described in the 10th edition of ''Systema Naturae'' by Carl Linnaeus with "European lakes" given as the type locality. 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 ''R. frisii''.
