Statistical analysis of the phytocoenose homogeneity. III. Spatial distributions of species and their standing biomass as a function of the area size

Abstract

Homogeneity of the Lcucobryo-Pineium phytocoenose was assessed on the grounds of species dispersal and spatial distribution of their biomass, determined with non-parametric runs test. It was confirmed that: 1) species dispersal and the type of spatial distribution of their biomass depended on the area size, 2) for analysed phytocoenose the area at which species dispersal and spatial sequence of the high and low standing biomass were random could be determined, 3) phytocoenose was homogeneous only under the difinite scale of its spatial differentiation, and 4) scale under which phytocoenose was homogenenous differed for qualitative and quantitative measures.
