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

Abstract

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