A total of 148 samples were taken; in the material of 1606 specimens 170 spider species were found. Over sixty years ago MIEDZIŃSKI(1934) recorded 119 species from that area. The results of our studies were compared with those of Miedziński, Table I: 69 species were recorded in both papers, 101 are new to the studied area, and 50 have not been confirmed. The differences in the species composition have several reasons: a) the studied area was gradually getting drier, b) the exploration time was short, c) not all collecting techniques were used, and not all habitat types were included in MIEDZIŃSKI's studies. The present list of spider species from the vicinity of Krotoszyn includes 220 species, 7 of them being new to Greater Poland-Kujawy Lowland.}, type={Text}, title={A comparison of the species composition of spider communities over sixty years in the vicinity of Krotoszyn}, keywords={Krotoszyn (region), ecology, arachnids, Arachnida, spiders, Araneae, Poland, Aranei, changes of the spider fauna}, }
