Statistical analysis of the phytocoenose homogeneity. V. Frequency distributions of similarity and distance coefficients as a function of the area size

Abstract

Homogeneity of the Leucobryo-Pinetum phytocoenose was assessed on the grounds of the type of frequency distributions of similarity and Euclidean distance coefficients. It was confirmed that: 1) the type of frequency distributions of similarity and distance coefficients, as well as values of their statistical characteristics depended on the area size; 2) for analysed phytocoenose the area size at which frequency distributions of both coefficients were symmetrical, i.e., fitted the normal distribution, could be determined; 3) at the same time such area determined the scale of spatial differentiation of the phytocoenose under which it was homogeneous.
