Biodiagnostics of urban soils of Melitopol urbosystem on the basic of the analysis of the ecomorphic mesofauna structure

The article deals with the results of biodiagnostics of urban
soils of Melitopol urbosystem on the basis of the analysis of the
ecomorphic mesofauna structure. It was established that increasing
the level of pollution of edaphotops by heavy metals in one case
causes the depression of the vitality of certain groups of
saprophages (representatives of the Isopoda class, the Enidae,
Helicidae families), in the other – the activation of their vitality
(representatives of the Diplopoda and Chilopoda classes, the
Lumbricida family and the Aranei row). The peculiarities of
ecomorphic structure and patterns of spatial-temporal dynamics of
the distribution groups of terrestrial mollusks should be used for
biodiagnostics of the ecological state of edaphotops.
