The American pika (Ochotona princeps) is known to maintain strict territorial boundaries, and dominance between individuals is enforced through a dominant pika invading another pika's territory, forcing the latter out. The general hierarchy of dominance has been observed (higher to lower in dominance) from male to female and adult to juvenile.
A high-ranking male mandrill advertises his status with bright facial coloration. [1]In the zoological field of ethology, a dominance hierarchy (formerly and colloquially called a pecking order) is a type of social hierarchy that arises when members of animal social groups interact, creating a ranking system.
Taxonomic rank is a classification level in biological taxonomy, such as species, genus, family, order, class, phylum, and kingdom.
In zoology, the nomenclature for the more commonly used ranks (superfamily to subspecies), is regulated by the International Code of Zoological Nomenclature (ICZN Code). [89] In the fields of phycology , mycology , and botany , the naming of taxa is governed by the International Code of Nomenclature for algae, fungi, and plants ( ICN ).
The hierarchy of biological classification's eight major taxonomic ranks. A class contains one or more orders. Intermediate minor rankings are not shown. Order (Latin: ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class.

Species can be placed in a ranked hierarchy, starting with either domains or kingdoms. Domains are divided into kingdoms . Kingdoms are divided into phyla (singular: phylum ) — for animals ; the term division , used for plants and fungi , is equivalent to the rank of phylum (and the current International Code of Botanical Nomenclature allows ...
