Spiders as indicators of biodiversity of agroeсosystems in low- and high-input farming systems

The effectiveness of spiders using as indicators of biodiversity in agroecosystems for low- and high-input farming is investigated. The analysis of spiders’ species diversity of different agroecenosis, semi-natural territories and ecotones between them is conducted in the article. The correlated quantity between species richness of spiders, it’s density in biotopes and indicators of agromanagement in according to low- and high-input farming are researched. The structural opportunities of spiders communities are analyzed, the most common and dominant species of spiders are defined. For the first time in Ukraine Ozyptila westringi (Thomisidae) was registered, that is more common in the territories of Sweden, Nederland and Germany. The tendency to grow for species richness density of spiders in habitats during agricultural season is revealed.

Key words: biodiversity indicator, spiders, agrocenosis, semi-natural habitats, ecotones.
