Hierarchical levels in syntaxonomy based on information functions

  • Published:
Vegetatio Aims and scope Submit manuscript

Summary

A method for defining syntaxa in sysystematics in an objective way is described. The method is based on measures of divergence of contingency tables obtained for the frequency distributions of species in given clusters, defined at different hierarchical levels of the dendrogram. The divergence is measured as an information function. The method is useful to compare different classifications.
