Die Pseudoskorpion-Fauna (Arachnida: Pseudoscorpiones) eines Auwaldes bei Ingelheim am Rhein, unter besonderer Berücksichtigung der Auswirkungen des trocken-warmen Winters 2006/2007
The pseudoscorpion-fauna (Arachnida: Pseudoscorpiones) of a floodplain close to Ingelheim/Rhine, with special reference to the effects of the dry-warm winter 2006/2007
Heft 35
From the beginning of May 2005 to September 2007 the pseudoscorpion fauna in a hardwood floodplain forest of the Rhine valley near Ingelheim was investigated. Altogether 587 individuals representing two species from two families were captured using pitfall traps, trunk eclectors and by litter sieving. The warm, dry winter 2006/2007 exhibited a strong influence upon the activity of Neobisium carcinoides (Hermann, 1804). This winter event was followed by an extreme drought in April 2007, which affected the activity maximum of the corticolous species Chernes hahnii (C.L. Koch, 1839). In 2005 and 2006 the activity maximum of C. hahnii was observed in July, whereas in 2007 maturity was achieved earlier in May. Furthermore 31 individuals of N. carcinoides were captured in trunk eclectors. This climbing behaviour correlates with the presence of Lepidocyrtus lignorum (Collembola: Entomobryidae) on the trunks.
