Thirty Years of Numerical Taxonomy
-In this history of numerical taxonomy since the publication in 1963of Sokal and Sneath's Principles of Numerical Taxonomy, I include reminiscences of the reactions of biologists in Britain and elsewhere. Much of the original program has proved sound. The debate on phenetic and phylogenetic classifications has been valuable, although the logical and theoretical aspects of phenetics have been gr...
متن کاملNumerical taxonomy of the genus Glycyrrhiza in the Hyrcanian region
Noticeable variation was observed in a number of morphological characters in the Glycyrrhiza specimens in various habitats in north of Iran. To study these variations, two taxa related to the Hyrcanian region from all four known taxa of this genus in Iran, including Glycyrrhiza echinata, and G. glabra var. glabra were studied by numerical taxonomy using morphological characters in three provinc...
متن کاملNumerical taxonomy of certain coryneform bacteria.
da Silva, G. A. Nigel (Iowa State University, Ames), and John G. Holt. Numerical taxonomy of certain coryneform bacteria. J. Bacteriol. 90:921-927. 1965-An electronic computer was used to sort 32 strains of coryneforms into groups with the tree-sort program. The similarity values obtained in this procedure were then used to construct a dendrogram depicting the phenetic resemblance among the tax...
متن کاملSpecific Numerical Taxonomy Methods in Biological Classification
There are presented automatic classification methods which, according to the authors' conceptions, are specific to biology. In section 1 there are included the necessary steps made in the automatic classification. In section 2 there are presented 2 methods of automatic classification which are frequently used in any field and in opposition with it the section 3 presents another method from lite...
متن کاملSub-dominant theory in numerical taxonomy
Sub-dominant theory provides efficient tools for clustering. However it classically works only for ultrametrics and ad hoc extensions like Jardine and Sibson’s 2ultrametrics. In this paper we study the extension of the notion of sub-dominant to other distance models in classification accounting for overlapping clusters. We prove that a given dissimilarity admits one and only one lower-maximal q...
