Karl Kessler
Karl Fedorovich Kessler (; – ) was a Baltic German zoologist who worked as a professor of biology at Saint Petersburg Imperial University. Among his contributions was the idea that evolution at an infraspecific level involved mutual aid and that Charles Darwin had placed too much emphasis on competition which he accepted as occurring at the interspecies level. Life and work Kessler was born in Damrau, Konigsberg, where his father was a royal forester (''oberforestmeister''). His father moved to Novgorod Governorate, where Kessler grew up. In 1828, he joined the with a scholarship and went to Saint Petersburg Imperial University in 1834. He attended the zoology lectures of Stepan Kutorga. After graduation he worked as a school mathematics teacher. In 1837, Kessler and his botanist friend from student days, went on an expedition to Finland. In 1840, he defended a master's dissertation on the legs of birds in relation to systematics. In 1842, his doctoral dissertation ...

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, ...

Dace
A dace is a small fish that can be one of many different species. The unmodified name is usually a reference to the common dace (''Leuciscus leuciscus''). This, like most fish called "daces", belongs to the family Leuciscidae, mostly in subfamily Leuciscinae. Daces in the Cyprinidae: * Common dace, '' Leuciscus leuciscus'' * Chinese mud carp, '' Cirrhinus chinensis'' (called "dace" in Hong Kong) or mud carp (''Cirrhinus molitorella'') * Columbia River dace, '' Ptychocheilus oregonensis'' (a pikeminnow) * Desert dace, '' Eremichthys acros'' (a monotypic genus) * European daces, genus ''Leuciscus'' * Fallfish, '' Semotilus corporalis'' (a creek chub called "dace" in Canada) * Horned dace, '' Semotilus atromaculatus'' (a creek chub) * Japanese dace '' Tribolodon hakonensis'', genus '' Tribolodon'' * Korean splendid dace, '' Coreoleuciscus splendidus'' * Lake Candidus dace, '' Candidia barbata'' * Mexican daces, genus †'' Evarra'' * Moapa dace, '' Moapa coriacea'' (a monotypic ...

Chub
Chub is a common fish name. It pertains to any one of a number of ray-finned fish in several families and general. In the UK, the term ''chub'' usually refers to the species '' Squalius cephalus''. In addition, see sea chub.

Phoxinus
''Phoxinus'' is a genus of freshwater fish in the family Leuciscidae of order Cypriniformes, and the only members of the subfamily Phoxininae, or Eurasian minnows. The other species in this genus are also commonly known as minnows. The name "minnow" was what early English fisherman used to describe "small and insignificant". The genus ''Phoxinus'' is found throughout Eurasia, and includes 21 known species. Previously, members of the North American genus '' Chrosomus'' were also believed to form part of this genus. Species ''Phoxinus'' contains the following species: * '' Phoxinus abanticus'' Turan, Bayçelebi, Özuluğ, Gaygusuz & Aksu, 2023 * '' Phoxinus adagumicus'' Artaev, Turbanov, Bolotovskiy, Gandlin & Levin, 2024 * '' Phoxinus bigerri'' Kottelat, 2007 (Pyrenean minnow) * '' Phoxinus brachyurus'' Berg, 1912 (Seven Rivers minnow) * '' Phoxinus chrysoprasius'' (Pallas, 1814) * '' Phoxinus colchicus'' Berg, 1910. * '' Phoxinus csikii'' Hankó, 1922 (Danube minnow) * ...

Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery 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. 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 (shark Sharks are a group of elasmobranch cartilaginous fish characterized by a ...

Taxa Named By Karl Kessler
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
