Abstract
The tree trunk-region of forests is rendered prominent as a habitat and traffic zone of arthropods. A great number of manifold activities in lower trunk areas may be determined by means of special collecting devices, so-called «arboreal photo-eclectors». For the first time artificial trunks were used, which were, in diameter and surface structure as well as in shape and arrangement, exactly equal to catch funnels. In this way, the actions of climbing up and flying to tree trunks yield comparable hints on structure and dynamics of arthropod coenoses and populations in different forests and in different years. — In research areas studied until now, Collembola are the predominating group, followed, in definite areas of the Swabian Alb, in 1978, by Diptera [esp. Cecidomyiidae, Phoridae], Arachnida [esp. Araneae, Acari], Rhynchota [esp. Heteroptera Miridae; Cicadina], Coleoptera [esp. Staphylinidae, Curculionidae], lepidopterous larvae and Hymenoptera [parasitic groups]. — Numerous Arthropoda, esp. groups or stages unable to fly or less active in flying, orientate markedly towards trunk-silhouettes. High tree trunks hold the greatest attraction, and among these best catch results are achieved by using funnels at a low distance from the ground.
