Barbatula Cobdonensis
''Barbatula cobdonensis'' is a species of freshwater ray-finned fish belonging to the family Nemacheilidae, the stone loaches. This loach is found in the lakes Khintiktig-Khol and Ak-Khol and in the Mogen-Buren River all within the drainage basin of the Kobdo River in northwestern Mongolia and the Tuva Republic in Russia. This taxon is placed with some uncertainty within the genus ''Barbatula'' as a ''species inquirenda'', or it may be a junior synonym In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently. ... of '' B. compressirostris''.

Aleksey Nikolaevich Gundriser
Alexey ( ; ), is a Russian and Bulgarian male given name derived from the Greek ''Aléxios'' (), meaning "Defender", and thus of the same origin as the Latin Alexius. Similar Ukrainian and Belarusian names are romanized as Oleksii (Олексій) and Aliaksiej (Аляксей), respectively. The Russian Orthodox Church uses the Old Church Slavonic version, Alexiy or Aleksiy (Алексiй, or Алексий in modern spelling), for its Saints and hierarchs (most notably, this is the form used for Patriarchs Alexius I and Alexius II). The name became fairly popular in Russia after the baptism of Michael of Russia's son, Alexis of Russia. The common hypocoristic is Alyosha () or simply Lyosha (). These may be further transformed into Alyoshka, Alyoshenka, Lyoshka, Lyoha, Lyoshenka (, respectively), sometimes rendered as Alesha/Aleshenka in English. The form Alyosha may be used as a full first name in Bulgaria (Альоша) and Armenia. In theory, Alexia is the female f ... [...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 ...

Nemacheilidae
The Nemacheilidae, or stone loaches, are a family of cypriniform fishes that inhabit stream environments, mostly in Eurasia, with one genus, ''Afronemacheilus'' found in Africa Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surfac .... The family includes about 790 species.

Tuva
Tuva (; ) or Tyva (; ), officially the Republic of Tyva,; , is a Republics of Russia, republic of Russia. Tuva lies at the geographical center of Asia, in southern Siberia. The republic borders the Federal subjects of Russia, federal subjects of the Altai Republic, Buryatia, Irkutsk Oblast, Khakassia, and Krasnoyarsk Krai, and shares an international border with Mongolia to the south. Tuva has a population of 336,651 (Russian Census (2021), 2021 census). Its capital city is Kyzyl, in which more than a third of the population reside. Historically part of Outer Mongolia as Tannu Uriankhai during the Qing dynasty, the last imperial dynasty of China, Tuva broke away in 1911 as the Uryankhay Republic following the 1911 Revolution, Xinhai Revolution, which created the Republic of China (1912–1949), Republic of China. It became a Uryankhay Krai, Russian protectorate in 1914 and was replaced by the nominally independent Tuvan People's Republic in 1921 (known officially as Tannu ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Barbatula
''Barbatula'' is a genus of fish in the family (biology), family Nemacheilidae native to Europe and Asia.Kottelat, M. (2012)Conspectus cobitidum: an inventory of the loaches of the world (Teleostei: Cypriniformes: Cobitoidei). ''Raffles Bulletin of Zoology, Suppl. No. 26: 1-199.'' They are found in streams, rivers and lakes, and the genus also includes Europe's only cavefish, which only was discovered in the Danube Sinkhole, Danube–Aachtopf system in Germany in 2015. ''Barbatula'' formerly included many more species, but these have been moved to other genera, notably ''Oxynoemacheilus''.

Species Inquirenda
In biological classification, a ''species inquirenda'' is a species of doubtful identity requiring further investigation. The use of the term in English-language biological literature dates back to at least the early nineteenth century. The term ''taxon inquirendum'' is broader in meaning and refers to an incompletely defined taxon of which the taxonomic validity is uncertain or disputed by different experts or is impossible to identify the taxon. Further characterization is required. Certain species names may be designated unplaced names, which ''Plants of the World Online'' defines as "names that cannot be accepted, nor can they be put into synonymy". Unplaced names may be names which were not validly published, later homonyms which are therefore illegitimate, or species which cannot be accepted because the genus name is not accepted. Species names may remain unplaced if there is no accepted species in a genus in which it can be placed, or if the type material for the species ...
