Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), [Note 1] form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC.
Taxon identifiers enable researchers to search more easily for pertinent information on the subject of an article, without needing to disambiguate the subject manually. For example, taxon identifiers are used in species articles so that the information in the article can be easily cross-referenced with the popular Catalogue of Life database.
The representation of taxonomic information in machine-encodable form raises a number of issues not encountered in other domains, such as variant ways to cite the same species or other taxon name, the same name used for multiple taxa , multiple non-current names for the same taxon , changes in name and taxon concept definition through time, and ...
MNHN-Tree-Tools: MNHN-Tree-Tools is an opensource phylogenetics inference software working on nucleic and protein sequences. Clustering of DNA or protein sequences and phylogenetic tree inference from a set of sequences. At the core it employs a distance-density based approach. Thomas Haschka, Loïc Ponger, Christophe Escudé and Julien ...
A new taxon is created for each of the other clades. [1] For the each new taxon, the curators try to find a proposed name in literature for it. If there is no name proposed, the taxon is given a placeholder name by adding a suffix to the original name, e.g. Lactobacillus gasseri_A. After "Z" comes "AA". [1]
Phylogenetic nomenclature is a method of nomenclature for taxa in biology that uses phylogenetic definitions for taxon names as explained below. This contrasts with the traditional method, by which taxon names are defined by a type, which can be a specimen or a taxon of lower rank, and a description in words. [1]
Taxoboxes display the "taxonomic hierarchy". ("Taxon" is a general term for a named group of organisms, such as a subspecies, a species, a family, an order, etc.) The taxonomic hierarchy shows the location of the taxon within a particular classification system; e.g. for a genus, it may show its family, order, etc. up to kingdom.
Taxonbar displays these links as short strings, indicating the unique identifier each database has assigned the taxon for catalogue purposes. Taxonomic identifiers of each taxon are stored and retrieved from each taxon's corresponding Wikidata entry, but can be overridden in individual articles with locally entered data. Adding the data to ...
