Twenty years of numerical syntaxonomy

open access: yesVegetatio, 1989
The development of numerical syntaxonomy during its first 20 yr is reviewed. The use of methods of numerical classification and ordination is the dominating feature of the development. National and local phytosociological data banks were established, large data sets handled and many important vegetation monographs were methodically based on ...

Hierarchical levels in syntaxonomy based on information functions

Plant Ecology, 1980
Numerical taxonomy (formalized cluster analysis) can be defined as a set of procedures which assign objects to groups in such a way that each group reveals some distinct characteristic of the sample population (Orloci 1978). This means in the classification of vegetation that any cluster of releves or synoptic tables can be syntaxonomically meaningful ...

Syntaxonomy of the Australian mangai refined through iterative ordinations

open access: yesVegetatio, 1989
Mangal (tidal forest) communities vary with respect to position in the littoral sequence, and latitude. A previous classification of mangal from the southern and western coastlines of Australia has been subjected to a series of ordinations, in an attempt to produce a robust syntaxonomy.

Assessment of vegetation β-diversity on the basis of syntaxonomy

Russian Journal of Ecology, 2014
Using the example of vegetation in four specially protected natural areas in the Southern Urals, it has been shown that its β-diversity can be estimated in two ways: from the number of syntaxa ranking from the class to the association and from the syntaxonomic spectrum, i.e., the ratio between associations of different classes.

Notes on syntaxonomy of cultural forest communities

Folia Geobotanica et Phytotaxonomica, 1980
It is suggested that communities of cultivated forests can be incorporated into the system of “natural” wood communities either as facies, variants or subassociations, if they differ below the association level; if they differ on the association level, a new association is suggested, with the prefix “culti-” before the planted dominant tree species ...
