Pavouci (Araneae) xerotermních trávníků a lomů Chráněné krajinné oblasti Blanský les

Abstrakt: Results of a survey of the arachnofauna of six xerothermous localities in the Blanský les Protected Landscape Area (southern Bohemia, Czech Republic) are presented. Three of the study sites were operating or freshly abandoned quarries (one limestone, two granulite), three were adjoining (sub)xerophilous grasslands; the survey method was pitfall trapping for one season. In total, 3,029 specimens of 132 Araneae species were recorded. Sitticus distinguendus (Simon, 1868) and Pellenes tripunctatus (Walckenaer, 1802) are new for the region of Southern Bohemia. The results point to the importance of insular, isolated xerophilous sites for maintaining high species diversity.
