Stevardiinae
Stevardiidae is a large Family (biology), family of freshwater fish in the Order (biology), order Characiformes. It includes many genera previously placed in the family Characidae, which was split into multiple families in 2024. They are found throughout South and Central America. In earlier taxonomic treatments, most genera in this family were placed in the characid subfamily Glandulocaudinae, which has been redefined as a much smaller subfamily of the Stevardiidae. As suggested by their former taxonomic name, a gland on their Fish anatomy, caudal fin is found almost exclusively in the males of many species of this family, which allows the release and pumping of Pheromone, pheromones. Members of this subfamily have complex courtship behaviors which lead to insemination. The ecology and life history of these fish is complex yet little studied. Stevardiids are important components of the diet for commercially-harvested larger fish. Taxonomy The following taxonomy is based on ''E ...

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 ...

Characin
Characiformes is an order of ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.; Buckup P.A.: "Relationships of the Characidiinae and phylogeny of characiform fishes (Teleostei: Ostariophysi)", ''Phylogeny and Classification of Neotropical Fishes'', L.R. Malabarba, R.E. Reis, R.P. Vari, Z.M. Lucena, eds. (Porto Alegre: Edipucr) 1998:123-144. Taxonomy The Characiformes form part of a series called the Otophysi within the superorder Ostariophysi. The Otophysi contain three other orders, Cypriniformes, Siluriformes, and Gymnotiformes. The Characiformes form a group known as the Characiphysi with the Siluriformes and Gymnotiformes. The order Characiformes is the sister group to the orders Siluriformes and Gymnotiformes, though this has been debated in light of recent molecular evidence. Originally, the characins were all grouped within a sing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided by precipitation variations than by temperature variations. The tropics maintain wide diversity of local climates, such as rain forests, monsoons, sa ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern Subregion#Americas, subregion of the Americas. South America is bordered on the west by the Pacific Ocean, on the north and east by the Atlantic Ocean, and to the south by the Drake Passage; North America and the Caribbean Sea lie to the northwest. The continent includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territory, dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one administrative division, internal territory: French Guiana. The Dutch Caribbean ABC islands (Leeward Antilles), ABC islands (Aruba, Bonaire, and Curaçao) and Trinidad and Tobago are geologically located on the South-American continental shel ...

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] |
Alberto Perugia
Alberto is the Romance version of the Latinized form (''Albertus'') of Germanic '' Albert''. It is used in Italian, Portuguese and Spanish. The diminutive forms are ''Albertito'' in Spain or ''Albertico'' in some parts of Latin America, Albertino in Italian as well as ''Tuco'' as a hypocorism. It derives from the name Adalberto which in turn derives from '' Athala'' (meaning noble) and ''Berth'' (meaning bright).

Taxa Named By Carl H
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] |
