In biological classification, subspecies (pl.: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics , but that can successfully interbreed. [2] [3] Not all species have subspecies, but for those that do there must be at least two.
[10] [11] The classification also includes seven fresh-water biomes and 5 marine biomes. [10] Each biome contains many ecoregions that are examples of that type of habitat. [10] The purpose of this classification scheme is to identify ecoregions that are conservation priorities. These priority regions are referred to collectively as the WWF's ...
Biology is the scientific study of life. [ 1 ] [ 2 ] [ 3 ] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [ 1 ] [ 2 ] [ 3 ] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted ...
The traditional classification of primates (class Mammalia, subclass Theria, infraclass Eutheria, order Primates) has been modified by new classifications such as McKenna and Bell (class Mammalia, subclass Theriformes, infraclass Holotheria) with Theria and Eutheria assigned lower ranks between infraclass and the order Primates.
The hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown. A species (pl.: species) is a population of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. [1]
The hierarchy of biological classification's eight major taxonomic ranks. A phylum contains one or more classes. Intermediate minor rankings are not shown. In biological classification, class (Latin: classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders.

The hierarchy of biological classification's eight major taxonomic ranks. Intermediate minor rankings are not shown. In zoological nomenclature, a subphylum is a taxonomic rank below the rank of phylum. The taxonomic rank of "subdivision" in fungi and plant taxonomy is equivalent to "subphylum" in zoological taxonomy.
