Phenetic Approaches to Classification
Academy of Natural Sciences Philadelphia, Pennsylvania 19103
An assessment of similarity among individuals, species, and higher taxa is an essential component of biological classification. Multivariate phenetic techniques can be used to carry out this task, and to provide a logical basis for the recognition of taxa and the construction of phylogenies. Cluster analysis and ordination are current techniques used to group by similarity. These techniques are discussed and some of them applied to a representative taxon of parasites, the mite family Harpyrhynchidae. Taxonomic structure within the family is described in terms of parasite morphology, host association, and probable coevolution.
