Zur Arthropodenfauna von Tagebaufolgelandschaften Sachsen-Anhalts: 1. Landasseln (Oniscoidea, Isopoda, Crustacea)

Abstract

BERGMANN, S.; WITSACK, W.: Arthropods of Saxony-Anhalt (Germany) open-cast post-mining landscapes. 1. Wood-lice (Oniscoidea, Isopoda, Crustacea)- Hercynia N. F. 34 (2001): 261-283. Between 1996-1998 investigations on lsopoda were carried out within the open-cast post-mining landscapes of Saxony-Anhalt. Species-lists taken from 94 locations are evaluated and characteristic species of the investigated habitat types are shown. Currently 7 species of lsopoda are known from postmining Iandscapes of Sachsen-Anhalt. These are 14 % of the known species in Saxony-Anhalt. The paper gives information about the distribution of the recorded species in different mining regions in Centtal Germany. It makes remarks on the habitat preferences of seven recorded lsopoda-species and the assessment of population densities. Finally the importance of the different habitat types for the Isopoda species is discussed. Most important are the dense vegetated varied grasslands and the forests. Characteristic species of dense vegetated varied grasslands are: Armadillidium vulgare, Porcellio scaber and Trachelipus rathkii. Armadillidium vulgare, Porcellio scaber, Oniscus asselus and Philoscia muscorum are characteristic species of forests.
