Ground-living spiders in a bottom land area of the Danube river in Bavaria (Germany)

The ground-living spider fauna of a drained bottom land forest area was investigated at 5 sites in the vicinity of the Danube river near Dillingen/Bavaria. Four series of pitfall traps were set up in the bottom land forest area, while a fifth series was installed in a dry, sunny clearing. Observation period was from early April through late November 1985. A total numberof 1447 adult spiders belonging to 94 species were oaught. The main result was that the small, dry clearing area harbors a rather specific spider community that is distinctly different from those of the neighbouring wet areas in the forest
