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").
Nomenclature codes or codes of nomenclature are the various rulebooks that govern the naming of living organisms. Standardizing the scientific names of biological organisms allows researchers to discuss findings (including the discovery of new species).
This page emphasizes absolute ranks and the rank-based codes (the Zoological Code, the Botanical Code, the Code for Cultivated Plants, the Prokaryotic Code, and the Code for Viruses) require them. However, absolute ranks are not required in all nomenclatural systems for taxonomists; for instance, the PhyloCode , [ 2 ] the code of phylogenetic ...
The ICPN, or PhyloCode, is a code of rules and recommendations for phylogenetic nomenclature. The ICPN only regulates clade names. Names for species rely on the rules of the traditional codes of nomenclature. The Principle of Priority (or "precedence") is claimed for names and for definitions within the ICPN. The starting point for priority was ...
The International Code of Phylogenetic Nomenclature, known as the PhyloCode for short, is a formal set of rules governing phylogenetic nomenclature. Its current version is specifically designed to regulate the naming of clades , leaving the governance of species names up to the rank-based nomenclature codes ( ICN , ICNCP , ICNP , ICZN , ICVCN ).
Biological taxonomy is not fixed, and opinions about the correct status of taxa at all levels, and their correct placement, are constantly revised as a result of new research. Many aspects of classification remain a matter of scientific judgment. The ITIS database is updated to take account of new research as it becomes available. [citation needed]
Engström et al. [14] suggest and evaluate the use of a taxonomy to bridge the communication between researchers and practitioners engaged in the area of software testing. They have also developed a web-based tool [15] to facilitate and encourage the use of the taxonomy. The tool and its source code are available for public use. [16]
Taxonomy is that part of Systematics concerned with topics (a) to (d) above. A whole set of terms including taxonomy, systematic biology, systematics, scientific classification, biological classification, and phylogenetics have at times had overlapping meanings – sometimes the same, sometimes slightly different, but always related and ...
