NEW OBJECTIVE METHOD FOR CALCULATING FIDELITY. EXAMPLE: THE ILLYRIAN BEECHWOODS

Abstract

The concept of fidelity and using character species has main importance in the methodics of Zürich-Montpellier phytosociological school. In spite of their long history and importance only few of papers study this question from methodical point of view. In this paper the fidelity concept and measures are shortly rewieved and Juhász-Nagy’s unfortunately not well-known fidelity concept is reconsidered. Information statistical (G2) functions are proposed to measure the three forms of fidelity. On the basis of this concept we suggest to distinguish faithful and character species. The application of new method is showed by an example: the Illyrian beechwoods.
