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 formal author, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN").
The ICZN is governed by the "Constitution of the ICZN", which is usually published together with the ICZN Code. [2] Members are elected by the Section of Zoological Nomenclature, [3] established by the International Union of Biological Sciences (IUBS). The regular term of service of a member of the Commission is six years.
The ICZN follows the Principle of Priority, in which the oldest available name for a taxon is generally the valid name. [4] Junior homonyms in the family and genus group – names of families and genera which have identical spelling, but refer to different taxa. Only one of two (or more) such homonyms can be valid; junior family-rank names must ...
Under the ICZN, two names of the same rank that have the same name-bearing type are objective synonyms, as are two whose name-bearing types are themselves objectively synonymous names; [7] for example, the names Didelphis brevicaudata Erxleben, 1777, and Didelphys brachyuros Schreber, 1778, were both based on a specimen (now in the British Museum of Natural History) described by Seba in 1734 ...
The ICNafp, the plant code, does not allow the two parts of a binomial name to be the same (such a name is called a tautonym), whereas the ICZN, the animal code, does. Thus the American bison has the binomen Bison bison; a name of this kind would not be allowed for a plant.
In 1963, its name was changed to the University of the Americas and in 1968 to the Universidad de las Américas. Since its founding the university has been located first in leased buildings at the Colonia Roma in Mexico City during the 1950s and later on an eight-acre campus on the Mexico-Toluca Road.
