Spiders (Arachnida, Araneae) inhabiting agroecosystem grass-level in Moscow region (species composition, spatial distribution, and seasonal dynamics)

摘要

The species composition of the araneocoraplex is almost identical to those of European countries in the temperate zone. The communities inhabiting various crops are similar taxonomically. A set of mass species ttmteveatent of a kind of crops. The number of species and their abundance are reduced toward the center of fields. Eurytopic meadow species and the species tvpical of declined biotopes are characteristic of the agroecosysterns. Thoimsidae (hortobiotk ambushers), Tetragnathidae and Linyphiidae(hortobiotic web-building spiders) Predominate there. The abundance of spiders in the central part of the field is insufficient to support the stability of arthropod complexes.
