Journal Title: KULON - Year 2016, Vol 21, Issue
Abstract
The study was conducted in the Lublin Province, mainly in High Nature Value farmlands along the valleys of the rivers Bug, Tyśmienica and Wieprz. Samples were collected during four years (2012-2015) in study plots located in winter cereals of organic (E) and low-input conventional farming systems (K). Epigeic and epiphytic spiders were caught by using pitfall traps and sweep net, respectively. In Total, 167 individuals from 30 rare and endangered species were collected, which accounted for 0.25% of the totally caught specimens and 13% of all species found. Two species belonged to the category ‘endangered’ (EN) in Poland; 20 species were vulnerable (VU) and seven species with deficient data (DD). The most abundant rare and endangered spider species were by name as follows: Thanatus arenarius, Pardosa maisa and Porrhomma microphthalmum. Statistically significant differences in the number of individuals and the number of rare and endangered spider species, between winter cereals in organic and low-input conventional farming systems were not revealed.
