For example, Motacilla alba alba (often abbreviated M. a. alba) is the nominotypical subspecies of the white wagtail (Motacilla alba). The subspecies name that repeats the species name is referred to in botanical nomenclature as the subspecies "autonym", and the subspecific taxon as the "autonymous subspecies". [12]
Variety is defined in the code as follows: "Variety (varietas) the category in the botanical nomenclatural hierarchy between species and form (forma)". The code acknowledges the other usage as follows: "term used in some national and international legislation for a clearly distinguishable taxon below the rank of species; generally, in ...
The basic ranks are species and genus. When an organism is given a species name it is assigned to a genus, and the genus name is part of the species name. The species name is also called a binomial, that is, a two-term name. For example, the zoological name for the human species is Homo sapiens. This is usually italicized in print or underlined ...
Differences between these two groups is attributed to phenotypic plasticity and are too few for them to be termed as wholly different species. [7] Emergence of variants of the same species may occur in the same geographical region where different habitats provide distinct ecological niches for these organisms examples of these habitats include ...
Range maps are provided wherever possible; if a range map is not available, a description of the canid's range is provided. Ranges are based on the IUCN Red List for that species, unless otherwise noted. All extinct species (or subspecies) listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol: "†".
For example, giraffe populations and subspecies differ genetically to such an extent that they may be considered species. Although the giraffe, as a whole, is not considered to be threatened, if each cryptic species is considered separately, there is a much higher level of threat.
A small, dark-colored subspecies, intermediate in size between youngi and baileyi. [117] Arizona and New Mexico: Currently (2022) synonymized under C. l. nubilus [1] [118] † C. l. monstrabilis Texas wolf: Goldman, 1937 [57] Similar in size and color to mogollonensis and possibly the same subspecies. [119] Texas, New Mexico, and northern Mexico
Today, it is treated as a single species with four subspecies. Along with the nominate subspecies A. g. guarauna, A. g. dolosus, A. g. elucus (both J. L. Peters, 1925), and A. g. pictus (F. A. A. Meyer, 1794) are recognized. The difference between the subspecies are related to slight differences in size and plumage. [6]
