CLUSTER ANALYSIS AND VEGETATION MESO-XERIC ORDERING IN MORI CA VALLEY BASIN (BOTO ANI COUNTY)

The aim of this paper is to classify, describe, and interpret the floristic structure of meso-xeric plant communities in the Mori ca Valley, by eco-cenotic data numerical analysis, interlinked with environmental gradients. A number of 92 relevès were analyzed by cluster analysis and grouped in 15 clusters. These clusters correspond to meso-xeric associations in Mori ca Valley. These associations have been ordered directly by canonical correspondence analysis (CCA).
