Herbage cover heterogeneity as indicator of ecology-phytocoenotical and biotopical diversity in oak forests

The article is devoted to the identification of biotope diversity. There were surveyed the oak forests grown on the steep ravine slope near the Severskiy Donets River (the Don basin) within the area of National Park "Homolshansky lisy" (Kharkiv region, Ukraine). Study of spatial heterogeneity of herbage cover structure allowed distinguishing statistically significantly the seven types of multi-species mosaics on the coenotical level, which are characterized by specific ecology-phytocoenotical specificity. Such types form coenotical, hygrogen-edaphogenic and climatogenic series of substitution reflected the habitat diversity of surveyed area (as markers of habitat) and were in accord with the typology units of forests in Ukraine. In this paper there were used methods of phytoindication, indirect ordination, and non-parametric correlation analysis

Environmental Aspects of the Effect of Earthworm (Lumbricidae, Oligochaeta) TrophoMetabolic Activity on the pH Buffering Capacity of Remediated Soil (Steppe Zone, Ukraine)

Environmental aspects of trophometabolic activity of soil saprophages on the pH buffering capacity of remediated soils in Ukraine was considered. Earthworm (Lumbricidae) casts have been proven experimentally to have a higher acid-base buffering capacity in comparison with that of the initial soil. Remediated soils enriched with earthworm casts become more resistant to negative anthropogenic effects. Thus, the activity of soil saprophages influences positively the environmental properties of remediated soils on forest remediation sites by increasing their buffer capacity
