Vliv různých travních směsí na společenstva pancířníků (Acari: Oribatida) v iniciálních sukcesních stádiích během obnovy květnatých luk

Altogether 400 quantitative soil samples were taken from 8 stationary plots in the localities Výzkum and Čertoryje in the Bílé Karpaty Mts. during the years 1999-2002. The present study is based on material of 10563 oribatid specimens belonging to 62 oribatid species. The lowest species richness and mean abundance were recorded on the plot with agricultural management.The highest mean abundance was found on the old sub-xerothermic meadow in Čertoryje. The eurytopic species .i.Scheloribates laevigatus./i. and .i.Tectocepheus velatus./i. as well as the heliophilous .i.Punctoribates punctum./i. were eudominant in all studied plots. These eudominant species were complemented by the dominant and recedent eurytopic species .i.Microppia minus, Hemileius initialis, Achipteria coleoptrata./i. and .i.Medioppia subpectimata./i.. The rare xerophilous species .i.Lucoppia burrowsi./i. was found in the plots sowed by different grass mixtures and in the fallow
