In taxonomy, binomial nomenclature, also called binominal nomenclature or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name, a binomen, binominal name or a scientific name; more informally it is also historically called a Latin name.
Przewalski's horse, also called the takhi, Mongolian wild horse or Dzungarian horse, is a rare and endangered horse originally native to the steppes of Central Asia. It is named after the Russian geographer and explorer Nikolay Przhevalsky. Once extinct in the wild, it has been reintroduced to its native habitat since the 1990s in Mongolia at the Khustain Nuruu National Park, Takhin Tal Nature Reserve, and Khomiin Tal, as well as several other locales in Central Asia and Eastern Europe.
Bovines comprise a diverse group of 10 genera of medium to large-sized ungulates, including cattle, bison, African buffalo, water buffalos, and the four-horned and spiral-horned antelopes. The evolutionary relationship between the members of the group is still debated, and their classification into loose tribes rather than formal subgroups reflects this uncertainty. General characteristics include cloven hooves and usually at least one of the sexes of a species having true horns. The largest extant bovine is the gaur.
Bos is the genus of wild and domestic cattle. Bos is often divided into four subgenera: Bos, Bibos, Novibos, and Poephagus, but including these last three divisions within the genus Bos without including Bison in the genus is believed to be polyphyletic by many workers on the classification of the genus since the 1980s. The genus as traditionally defined has five extant species but this rises to eight when the domesticated varieties are counted as separate species, and ten when the closely related genus Bison is also included. Most but not all modern breeds of domesticated cattle are believed to have originated from the extinct aurochs. Many ancient breeds are thought to have originated from other species. Zebus and taurine cattle are thought to descend from ancient Indian and Middle Eastern aurochs, respectively.
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its publisher, the International Commission on Zoological Nomenclature. The rules principally regulate:
The domestic yak, also known as the Tartary ox, grunting ox or hairy cattle, is a species of long-haired domesticated cattle found throughout the Himalayan region of the Indian subcontinent, the Tibetan Plateau, Kachin State, Yunnan, Sichuan, Gilgit-Baltistan (Kashmir), and as far north as Mongolia and Siberia. It is descended from the wild yak.
A holotype is a single physical example of an organism, known to have been used when the species was formally described. It is either the single such physical example or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept.
Heck cattle are a hardy breed of domestic cattle. These cattle are the result of an attempt by Heinz and Lutz Heck to breed back the extinct aurochs from modern aurochs-derived cattle in the 1920s and 1930s. Controversy revolves around methodology and success of the programme. There are considerable differences between Heck cattle and the aurochs in build, height, and body proportions. Furthermore, there are other cattle breeds which resemble their wild ancestors at least as much as Heck cattle.
The term tarpan refers to free-ranging horses of the Russian steppe from the 18th to the 20th century. It is generally unknown whether those horses represented genuine wild horses, feral domestic horses or hybrids. The last individual believed to be a tarpan died in captivity in the Russian Empire during 1909.
The International Commission on Zoological Nomenclature (ICZN) is an organization dedicated to "achieving stability and sense in the scientific naming of animals". Founded in 1895, it currently comprises 26 commissioners from 20 countries.
The wild horse is a species of the genus Equus, which includes as subspecies the modern domesticated horse as well as the endangered Przewalski's horse. The European wild horse known as the tarpan that went extinct in the late 1800s has previously been classified as a subspecies of wild horse, but more recent studies have cast doubt on whether those horses were truly wild or if they actually were feral horses or hybrids.
In zoological nomenclature, the valid name of a taxon is the sole correct scientific name. The valid name should be used for that taxon, instead of any other name that may currently be being used, or may previously have been used. A name is valid when, and only when, it is in harmony with all the relevant rules listed in the International Code of Zoological Nomenclature (ICZN). A valid name is the correct zoological name of a taxon.
A conserved name or nomen conservandum is a scientific name that has specific nomenclatural protection. That is, the name is retained, even though it violates one or more rules which would otherwise prevent it from being legitimate. Nomen conservandum is a Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the International Code of Nomenclature for Algae, Fungi, and Plants (ICN), while the International Code of Zoological Nomenclature favours the term "conserved name".
Asinus is a subgenus of Equus that encompasses several subspecies of the Equidae commonly known as wild asses, characterized by long ears, a lean, straight-backed build, lack of a true withers, a coarse mane and tail, and a reputation for considerable toughness and endurance.
The wild water buffalo, also called Asian buffalo, Asiatic buffalo and wild buffalo, is a large bovine native to the Indian subcontinent and Southeast Asia. It has been listed as Endangered in the IUCN Red List since 1986, as the remaining population totals less than 4,000. A population decline of at least 50% over the last three generations is projected to continue. The global population has been estimated at 3,400 individuals, of which 3,100 (91%) live in India, mostly in Assam. The wild water buffalo is the most likely ancestor of the domestic water buffalo.
AnimalBase is a project brought to life in 2004 and is maintained by the University of Göttingen, Germany. The goal of the AnimalBase project is to digitize early zoological literature, provide copyright-free open access to zoological works, and provide manually verified lists of names of zoological genera and species as a free resource for the public. AnimalBase contributed to opening up the classical taxonomic literature, which is considered as useful because access to early literature can be difficult for researchers who need the old sources for their taxonomic research.
The book Svenska Spindlar or Aranei Svecici is one of the major works of the Swedish arachnologist and entomologist Carl Alexander Clerck and was first published in Stockholm in the year 1757. It was the first comprehensive book on the spiders of Sweden and one of the first regional monographs of a group of animals worldwide. The full title of the work is Svenska Spindlar uti sina hufvud-slägter indelte samt under några och sextio särskildte arter beskrefne och med illuminerade figurer uplyste – Aranei Svecici, descriptionibus et figuris æneis illustrati, ad genera subalterna redacti, speciebus ultra LX determinati, and included 162 pages of text and six colour plates. It was published in Swedish, with a Latin translation printed in a slightly smaller font below the Swedish text.
The wild yak is a large, wild bovine native to the Himalayas. It is the ancestor of the domestic yak.
Tibicen is an historical genus name in the insect family Cicadidae that was originally published by P. A. Latreille in 1825 and formally made available in a translation by A. A. Berthold in 1827. The name was placed on the Official Index of Rejected and Invalid Generic Names in Zoology by the International Commission on Zoological Nomenclature in 2021. Certain European cicada species that were included by some authors in this genus at the time of its suppression are now listed under genus Lyristes Horváth, 1926. Other formerly-Tibicen species are placed in the tribe Cryptotympanini and include the genera Auritibicen Lee, 2015, Hadoa Moulds, 2015 Megatibicen Sanborn and Heath, 2016, and Neotibicen Hill and Moulds, 2015.
The Wells and Wellington affair was a dispute about the publication of three papers in the Australian Journal of Herpetology in 1983 and 1985. The periodical was established in 1981 as a peer-reviewed scientific journal focusing on the study of amphibians and reptiles (herpetology). Its first two issues were published under the editorship of Richard W. Wells, a first-year biology student at Australia's University of New England. Wells then ceased communicating with the journal's editorial board for two years before suddenly publishing three papers without peer review in the journal in 1983 and 1985. Coauthored by himself and high school teacher Cliff Ross Wellington, the papers reorganized the taxonomy of all of Australia's and New Zealand's amphibians and reptiles and proposed over 700 changes to the binomial nomenclature of the region's herpetofauna.
