Abstract: Ground beetle fauna of 35 nature reserves in the Łodź Province is summarized based on the literature data and unpublished records. For all studied reserves new faunistic data are presented, including first records of Carabidae for eight of them. In total, 140 ground beetle species (27.22% of Polish fauna and 54% of species recorded in the area of the Łodź Province) are noted from 35 (39%) nature reserves located in the Łodź Province. Moreover, it has been found, that the reserves “Rawka” and “Spala” encompass some of the highest Carabidae species richness noted among the all Polish nature reserves. Among the beetles recorded in the studied nature reserves, there are 16 species protected by Polish law, including 13 species of Carabus L. and 3 of Calosoma Web., what means 50% of Polish fauna and76.19% of protected carabid species occurring in the Łodź Province. Twelve species are included in the Polish RedData List: three species as critically endangered (CR) (Badister dorsiges, Patrobus australis, Trechus austriacus), one as endangered (EN) (Carabus clatratus), two as vulnerable (VU) (Odacantha melanura and Oodes helopioides), four as near threatened (NT) (Calosoma sycophanta, Carabus convexus, Diachromus germanus, and Omophron limbatum), one as least concern (LC) (Carabus intricatus), and one in “data deficient” category (DD) (Broscus cephalotes). High number of Carabidae species recorded on a relatively very small area of investigated nature reserves (in total only 0.29% of the Łodź Province) proves their importance in the conservation of species diversity of Carabidae in Poland.

Abstract: Summary The aim of the present research carried out in the vicinity of Bydgoszcz (the Kujawy and Pomorze Province) was to investigate whether the cultivation system affects the qualitative and quantitative composition of Carabidae. The catches were performed staring from the first decade of May to the first decade of August, over 2008–2009, on the plantations of winter triticale grown in two systems, organic and traditional. Over the two‐year research period 4716 beetles were caught from the Carabidae family. The beetles represents 21 genera, of which 2892 individuals – on the organic farm and 1824 – on the traditional farm. The eudominants were represented by the following genera: Harpalus spp., Poecilus spp., Pterostichus spp., Calathus spp. The least abundant were the species of the genera of Notiophilus spp., Dyschirius spp., Broscus spp., Bradycellus spp., Badister spp., Platynus spp. and Zabrus spp.
