Incorrect Subsequent Spelling
In zoological nomenclature, an incorrect subsequent spelling is a name whose spelling has been unjustifiably and unintentionally changed from the original. It is distinct from a " mandatory change", a change to the original spelling that is required by the ''International Code of Zoological Nomenclature'', and an "emendation", an intentional change to a name that may or may not be justified. For example, the rice rat ''Oryzomys peninsulae'' has occasionally been called "''Oryzomys peninsularis''", an incorrect subsequent spelling. If an incorrect subsequent spelling is in "prevailing usage", it is to be conserved. For example, although the name of the pathogen ''Trypanosoma brucei ''Trypanosoma brucei'' is a species of parasitic kinetoplastid belonging to the genus ''Trypanosoma'' that is present in sub-Saharan Africa. Unlike other protozoan parasites that normally infect blood and tissue cells, it is exclusively extracel ...'' was originally spelled ''brucii'', the spelling '' ...

Zoological Nomenclature
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 (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of binominal nomenclature * Which name must be used in case of name conflicts * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus ''Abronia'' in both animals and plants). The rules and recommendations have one fundamental aim: to provide the maximum universality and continuity in the naming of all animals, except where taxonomic judgment dictates otherwise. The code is meant to guide on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mandatory Change
Mandate most often refers to: * League of Nations mandates, quasi-colonial territories established under Article 22 of the Covenant of the League of Nations, 28 June 1919 * Mandate (politics), the power granted by an electorate Mandate may also refer to: * Mandate (after shave), British after shave brand * Mandate (criminal law), an official or authoritative command; an order or injunction * Mandate (international law), an obligation handed down by an inter-governmental body * ''Mandate'' (magazine), a monthly gay pornographic magazine * Mandate (trade union), a trade union in Ireland * , various ships of Britain's navy * Mandate (typeface), a brash-brush typeface designed by R. Hunter Middleton * The formal notice of decision from an appeals court * A requirement for a Health maintenance organization to provide a particular product See also * Contract of mandate, a contract of bailment of goods without reward, to be carried from place to place, or to have some act performed abo ...

Oryzomyini
Oryzomyini is a tribe of rodents in the subfamily Sigmodontinae of the family Cricetidae. It includes about 120 species in about thirty genera,Weksler et al., 2006, table 1 distributed from the eastern United States to the southernmost parts of South America, including many offshore islands. It is part of the clade Oryzomyalia, which includes most of the South American Sigmodontinae. The name ''Oryzomyini'' derives from that of its type genus, ''Oryzomys'', which means "rice rat" or "rice mouse". Many species are also known as rice rats. Taxonomy Contents of Oryzomyini An oryzomyine group was first envisaged by Oldfield Thomas in the early 20th century. He defined it to include pentalophodont species, which have a mesoloph(id) on the upper and lower molars, with a long palate (extending past the third molars). Thomas included ''Oligoryzomys'', '' Oecomys'', and ''Oryzomys'' (which included many species now in other genera), as well as ''Rhagomys'', which is currently classi ...

Oryzomys Peninsulae
''Oryzomys peninsulae'', also known as the Lower California rice rat, is a species of rodent from western List of mammals of Mexico, Mexico. Restricted to the southern tip of the Baja California peninsula, it is a member of the genus ''Oryzomys'' of family Cricetidae. Only about twenty individuals, collected around 1900, are known, and subsequent destruction of its riverine habitat may have driven the species to extinction. Medium in size for its genus, it was first described as a separate species, but later lumped into other, widespread species until it was reinstated as separate in 2009. It is distinctive in fur color—grayish brown on the forequarters and reddish brown on the hindquarters—and in some dimensions of its skull, with a high braincase, robust zygomatic arches (cheekbones), and long incisive foramen, incisive foramina (perforations of the palate between the incisors and the molar (tooth), molars). Taxonomy ''Oryzomys peninsulae'' was first collected in 1896 and O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trypanosoma Brucei
''Trypanosoma brucei'' is a species of parasitic kinetoplastid belonging to the genus ''Trypanosoma'' that is present in sub-Saharan Africa. Unlike other protozoan parasites that normally infect blood and tissue cells, it is exclusively extracellular and inhabits the blood plasma and body fluids. It causes deadly vector-borne diseases: African trypanosomiasis or sleeping sickness in humans, and animal trypanosomiasis or ''nagana'' in cattle and horses. It is a species complex grouped into three subspecies: ''T. b. brucei'', ''T. b. gambiense'' and ''T. b. rhodesiense''. The first is a parasite of non-human mammals and causes ''nagana'', while the latter two are zoonotic infecting both humans and animals and cause African trpanosomiasis. ''T. brucei'' is transmitted between mammal hosts by an insect vector belonging to different species of tsetse fly (''Glossina''). Transmission occurs by biting during the insect's blood meal. The parasites undergo complex morphological changes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
