Stipetum novakii ass. nova - A new association of serpentine rocky grassland vegetation (Halacsyetalia sendtneri) in Serbia

Abstract

Phytosociological characteristics of grassland communities above serpentines (order Halacsyetalia sendtneri H. Ritter-Studnička 1970) in Serbia, are analyzed according to Braun-Blanquet methodology. In order to detect the basic floristic differentiation of analyzed communities ordinary correspondence analysis was applied. Cluster analysis was also performed to see the structure and separation of the communities based on the floristic composition. In order to determine diagnostic species, fidelity indices with presence/absence data and the size of all groups standardized to equal size were calculated. The new association Stipetum novakii is described in open rocky serpentine grasslands in Brdjani Gorge. © 2013 by Acta Botanica Croatica, the Faculty of Science, University of Zagreb.
