2009
N.Yu. Polchaninova
191 spider species from 20 families were recorded for the Streletsky part of the TsentralnoChernozemny Nature reserve. The largest number of species was registered in the strictly protected steppe and on the ravine slopes with steppe vegetation i.e. in the open habitats with well-developed intact herbage; the least number was found in the forest under the canopy and in the steppe with a mowing regime. In the forest herbage, species richness and number of individuals are higher than in the steppe, and increase gradually from spring to autumn. In litter, the density of slow-moving dwellers is a maximum in the strictly protected steppe and in a minimum in the mowed steppe, while in the forest habitats it amounts to medium figures, higher under the canopy than on the glades. Dynamic density, on the contrary, is the lowest in the bottom of forest ravines and in the dark forest, being the highest at the forest edge, slopes of bairak forest, and in the strictly protected steppe
