The red-tailed silverside, or zona (''Bedotia geayi'') is a species of Madagascar rainbowfish endemic to the Mananjary River drainage in Madagascar. It is threatened by habitat loss and introduced species. It has often been confused with the related '' B. madagascariensis'', which is common in the aquarium trade.SeriouslyFish: Bedotia madagascarensis.' Retrieved 3 July 2014.Loiselle, P.V.; and Rodriguez, D. (2007).

Zootaxa 1520: 1-18. In addition to meristics, the two can be separated by the exact colour pattern on their tail fin (males of both typically have red in the tail) and the distinct red spot on the lower jaw of breeding male ''B. geayi'' (lacking in ''B. madagascariensis''). ''B. geayi'' was described in 1907 by Jacques Pellegrin from a type collected by the pharmacist and natural histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques Pellegrin
Jacques Pellegrin (12 June 1873 – 12 August 1944) was a French zoology, zoologist. Biography Pellegrin was born in Paris on 12 June 1873. He worked under zoologist Léon Vaillant (chair of reptiles and fishes) at the ''Muséum national d'histoire naturelle''. From 1897, Pellegrin served as ''préparateur'' at the museum. He obtained doctorates in medicine (1899) and science (1904), and in 1908 was named as an assistant director. After many missions abroad, he became sub-director of the museum in 1937, and replaced Louis Roule (1861–1942) as the chairperson of herpetology and ichthyology. He published over 600 scientific books and articles and scientifically described around 350 new species. He named a number of fishes from the family Cichlidae, such as the genera ''Astatoreochromis'', ''Astatotilapia'', ''Boulengerochromis'', ''Lepidiolamprologus'', ''Nanochromis'' and ''Ophthalmotilapia''. Pellegrin fought with the French Resistance during World War II. He was killed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Madagascar
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] |
Bedotia
''Bedotia'' is a genus of the family (biology), family Bedotiidae of fishes Endemism, endemic to Madagascar. Taxonomy This genus is monophyly, monophyletic. Little is known regarding phylogenetics, phylogenetic interrelationships of the numerous populations of ''Bedotia'' of eastern Madagascar, and the genus is in need of systematic revision. One author synonym (taxonomy), synonymized ''B. longianalis'' and ''B. tricolor'' with ''B. geayi'' with no justification. It is apparent that several species of ''Bedotia'' exist, although many of these are new to science and await Species description, description, whereas the taxonomic status of many nominal species remains uncertain. A 2004 study supported three major, more or less geographically distinct, clades of ''Bedotia'', one comprising species with distributions ranging from mid- to southeastern Madagascar (''B. madagascariensis'', ''B. geayi'', and ''B. tricolor'', plus four undescribed species), another including species restric ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Pharmacist
A pharmacist, also known as a chemist in English in the Commonwealth of Nations, Commonwealth English, is a healthcare professional who is knowledgeable about preparation, mechanism of action, clinical usage and legislation of medications in order to dispense them safely to the public and to provide consultancy services. A pharmacist also often serves as a primary care provider in the community and offers services, such as health screenings and immunizations. Pharmacists undergo university or graduate-level education to understand the biochemical mechanisms and actions of drugs, drug uses, therapeutic roles, side effects, potential drug interactions, and monitoring parameters. In developing countries, a diploma course from approved colleges qualifies one for pharmacist role. This is mated to anatomy, physiology, and pathophysiology. Pharmacists interpret and communicate this specialized knowledge to patients, physicians, and other health care providers. Among other licensing ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is ...

Meristics
Meristics is an area of zoology and botany which relates to counting quantitative features of animals and plants, such as the number of fins or scales in fish. A meristic (countable trait) can be used to describe a particular species, or used to identify an unknown species. Meristic traits are often described in a shorthand notation called a ''meristic formula''. Meristic characters are the countable structures occurring in series (e.g. myomeres, vertebrae, fin rays). These characters are among the characters most commonly used for differentiation of species and populations. In the salmonids, scale counts have been most widely used for the differentiation of populations within species. In rainbow and steelhead trout the most notable differences among populations occur in counts of scales. Meristic comparison is used in phenetic and cladistic analysis. Meristic analysis A meristic study is often a difficult task. For example, counting the features of a fish is not as easy as ...

Madagascar Rainbowfish
Bedotiidae are a family of fish in the order Atheriniformes. They are closely related to the Australian rainbowfish family Melanotaeniidae, and were formerly placed in it as a subfamily, but are now considered a distinct family. They are commonly known as the Madagascar rainbowfish, Madagascan rainbowfish, or Malagasy rainbowfish due to their endemism to Madagascar. It includes two genera, ''Bedotia'' and ''Rheocles''. Taxonomy This family is monophyletic and includes the two genera ''Bedotia'' and '' Rheocles'', with at least 16 species. This group is considered by Nelson, 2016 '' Fishes of the World'' to be a subfamily of the family Melanotaeniidae. However, more recent authorities such as '' Eschmeyer's Catalog of Fishes'' treat it as its own family. When treated as a family it has been placed by some authorities in a suborder Melanotaenioidei which includes the sister groups Bedotiidae and Melanotaeniidae, as well as Pseudomugilidae (including Telmatherininae).

Bedotia Madagascariensis
''Bedotia madagascariensis'' (zona) is a species of fish in the family Bedotiidae. It is endemic to Madagascar, where found in rivers and lakes between the Ivoloina River and the Manambolo Creek. It is commonly seen in the aquarium trade, where it often has been confused with the related '' B. geayi''.SeriouslyFish: Bedotia madagascarensis.' Retrieved 3 July 2014. It is threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease .... It was described by Charles Tate Regan in 1903, with Madagascar given as the type locality, Regan deposited the type in the '' Muséum d'histoire naturelle de Genève'' and named the genus in honour of its director Maurice Bedot (1859–1927).

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
