Labeobarbus Intermedius
''Labeobarbus intermedius'' is an East African ray-finned fish species in the family Cyprinidae. Like the closely related yellowfish, it is hexaploid. A large species, the maximum recorded standard length is nearly . This species has a subspecies named '' Labeobarbus intermedius intermedius''. Systematics and taxonomy The year of its first description – as ''Barbus intermedius'' – was for some time erroneously reported as 1837. ''L. intermedius'' was still placed by most modern authors in the "wastebin genus" ''Barbus'' by default, and the IUCN still does so until a thorough taxonomic revision of the African "barbs" is published. However, the species is increasingly being restored to the related yellowfish genus ''Labeobarbus'', which seems a much more appropriate placement. It is a close relative of ''Labeobarbus bynni'', another African "barb". No subspecies are recognized at present. The population from the Barino River basin invalidly described as ''L. i. austr ...

Barb (fish)
A barb is one of various ray-finned fish species in a non-phylogenetic group, with members in the family Cyprinidae, and especially the genera ''Barbus'' and '' Puntius'', but many others also. They were formerly united with the barbels in the subfamily Barbinae but that group is paraphyletic with the Cyprininae. If the Labeoninae are recognized as distinct, many small African "barbs" would probably, however, warrant recognition as a new subfamily. The root of the word "barb" is common in cyprinid names of European languages, from the Latin ''barba'' ("beard") (COD): * ''barb'' from Catalan * ''barbi'' from Finnish * ''barbo'' from Spanish * ''barbeau'' from French * ''barbo'' from Italian and many others. This is in reference to the barbels which are prominently seen around the mouth of many "barbs". Genera Genera that contain species with common names including "barb": * '' Barbichthys'' * ''Barbodes'' * ''Barboides'' * ''Barbonymus'' – tinfoil barbs * '' Barbopsis ...

Ripon Barbel
The Ripon barbel (''Labeobarbus altianalis'') is an East African ray-finned fish species in the family Cyprinidae. A notably large barb, its maximum recorded total length is . Taxonomy Like other African "barbs", placement of this species in ''Barbus'' – the genus of the typical barbels and relatives – was provisional. Though called "barbel", it is probably not closely enough related to the typical barbels – the core group of ''Barbus'' – to be considered congeneric. Several supposedly distinct species have been merged into ''B. altianalis'', and numerous subspecies have been proposed. None of these are deemed valid. Some authorities place this species in the genus Labeobarbus. On the other hand, '' B. longifilis'', '' B. paucisquamatus'' and '' B. somereni'' were once considered subspecies of ''L: altianalis'', the second as sspp. ''lobogenysoides'' and ''paucisquamata'' and the third as ssp. ''urundensis''. Significant junior synonyms of ''L. altianal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbus Eurystomus
''Labeobarbus johnstonii'' is a species of cyprinid fish. It has long been placed in ''Barbus'', the "wastebin genus" for barbs, by default, and this is still being done by the IUCN. However, the species is increasingly being restored to related yellowfish genus ''Labeobarbus'' which seems a much more appropriate placement. It is presumably hexaploid like the other yellowfish. The supposed subspecies ''latirostris'' of its relative '' L. intermedius'' is actually misidentified ''L. johnstonii''.Vreven ''et al.'' (2006), de Graaf ''et al.'' (2007) Its natural habitats are rivers and freshwater lakes. It is found in Lake Malawi, the Shire River and their larger tributaries in Malawi, Mozambique and Tanzania. Like other yellowfish, ''L. johnstonii'' is a large species. It can grow to more than standard length and over in weight. This freshwater fish is found in small group in all sorts of underwater habitat. They are omnivores, but adult fish like to eat smaller fishes in par ...

Junior Synonym
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia lev ...

Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural 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. 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 set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
