Comparative analysis of collembolan fauna on the territory of Ukraine

Study of springtails fauna is conducted in different spatial scale from local to regional. It is suggested to divide the regions study into groups: microregions, mesoregions, macroregions and megaregions, taking into account their area. Due to interchanging of one taxa the spatial gradients of ecological conditions of the Ukraine, high level of general taxonomical diversity of regional, concrete and cenotic collembolanfaunae is provided. A comparative study of zonal springtails faunae confirmed a supposition about possibility of consideration of forest-steppe zone not in composition of the Steppe area arid, but within the limits of Temperate area humid. The concrete collembolanfaunae are better differentiated after quality composition of genera and species, than by their number. The concrete fauna of the Transcarpathian Lowland possesses low similarity with the faunistic complex of Carpathians. It follows to examine its composition in flat faunistic complex of broad-leaved zone. The rule of the double diminishing of size of collembolanfauna is formulated in the row of mesoregion (territory of the Ukraine) – microregion (natural zone, mountain country) – locality (local level) – biocenosis. On the basis of local fauna cluster analysis, two types of faunistic borders in the western part of Ukraine are selected: zonal and regional
