however their taxonomic ranks were uncertain due to the lack of criteria to define them within traditional taxonomy.In this study,we analyzed ITS sequence data from 745 collections(nearly 600 being newly generated)including 86 from type specimens of previously recognized subgenera and sections.Many ...
Diversity in the group is generally most conveniently represented at the level of the taxonomic rank of order. Within the platyhelminths this rank is relatively informative and much more numerically manageable than lower ranks such as family or genus (for example, there are 42 orders versus 401 ...

A recent trend in systematics is to eliminate ranks altogether or, alternatively, to permit unranked names between the major rank names (see Chapter 16). In either case, the taxon names, minus ranks, would still retain their hierarchical, evolutionary relationship (e.g., as in Figure 2.19D)...
PhyloRank can calculate the relative evolutionary divergence (RED) of taxa in a tree in order to identify taxa at a given taxonomic rank that have conspicuous placements in the tree. This information can be used to refine the placement of taxa in the tree with the aim of taxa at the same...
ranks. There are seven main taxonomic ranks: kingdom, phylum or division (see table), class, order, family, genus, species. In addition, the domain (proposed by Carl Woese) is now widely used as one of the fundamental ranks, although it is not mentioned in any of the Nomenclature Codes...
Taxonomic ranks are subjectively defined constructs based on dissimilarities between individuals or groups of organisms, with higher ranks representing higher-order groupings. The establishment of a Linnaeus-type hierarchy and binomial n... KT Konstantinidis,E Stackebrandt - Springer Berlin Heidelberg 被...
Global comparisons of beta diversity among mammals, birds, reptiles, and amphibians across spatial scales and taxonomic ranks Beta diversity is the change in species composition among areas in a geographic region. The proportion of species shared between two areas often decreases ... Hong,QIAN - 《...
Using the unconstrained algorithm, the TNRS ranks all candidate matches by descending SNMS, OMS and taxonomic status. Taxonomic status is ranked as follows: “accepted” > “synonym” > “no opinion” ("illegitimate" and "invalid" are treated as "synonym" for ranking purposes). The highest ran...
