Statistical analysis of the phytocoenose homogeneity. I. Distribution of the total species diversity and evenness indices as a homogeneity measure

Abstract

Homogeneity of the Leucobryo-Pinetum phytocoenose was assessed on the grounds of distributions of the total species diversity (H) and evenness e indices. In spite of the uniform physiognomy of the patch. caused by pure, even-aged, one-layered forest stand and apparent dominance of dwarf-shrubs in the ground layer, phytocoenose under study was heterogeneous. It resulted in the discrepancy between empirical distributions of H and e, and the normal distribution, as well as in the contagious spatial distributions of both indices.
