Spiders (Araneae) of the selected synanthropic environments in Lublin City

Abstract

Material collected in the area of Lublin City in typical synanthropicenvironments were worked out. Collected species, depending on thelevel of attachment, were classified to 3 ecological groups: eusynanthropicspecies, hemisynanthropic and asynanthropic ones. The differencein frequency of occurring and numbers of many species were noticed,depending on the type of synanthropic environment. It was observedthat outdoor walls of buildings were eagerly inhabited by species,which are associated with bark in natural conditions. This suggeststhat those species may supply the groups of synanthropic spidersin the future. Among 97 spiders recorded, the occurrence of Dipoenatorva (TH.) and Leptorchestes berolinensis (C.L.K.) - very rare speciesin Poland and Central Europe was worth mentioning. It was also found,that Achaearanea tabulata LEVI is a stable and common element ofPolish arachnofauna.
