Ground inhabiting spiders were investigated during the vegetation periods of , 1998 and 2000 in four pine forests of Brandenburg, Germany. 1995 three of them were managed in different ways and one area served as a control. In total 105 different species were found and the lowest number of species was found on the control area. Due to the management the pine forests got opened and xerophilous species could settle the areas. In total a heterogeneous species community was found on each area. From year to year high rates of species turnover were measured even for the dominant species (> 5 % of all collected individuals per area and year). Some endangered species in Brandenburg were collected as well.

Remarks on first records of two spider species in Brandenburg.

Records of Clubiona similis L. Koch, 1867 in the Upper Rhine area in Baden-Württemberg/Germany (Araneae: Clubionidae)

In this third supplement to the Catalogue of Swiss spiders of Maurer & Hänggi (1990) 9 species are recorded for the first time for Switzerland. 4 additional species already published elsewhere are added to the list of Swiss spiders. 5 other earlier published species are listed, which are only known from greenhouses or under similar eusynanthropic conditions. The list of spiders known to Switzerland today comprises 944 species.

The first record of Chthonius (C.) alpicola (Pseudoscorpiones, Chthoniidae) in Germany and new localities in Austria are presented.
