![]() ![]() Ordination analyses (NMDS) and MANOVA revealed no significant differences in spider and carabid beetle species compositions of the catches. Generalised linear models indicated no significant differences in arthropods counts among catches of pitfall traps of the four different designs, except for woodlice. The study was carried out in an oak-beech forest in Northwest Germany using a total of 40 pitfall traps (ten replicates per trap design). During the present study pitfall traps of four different designs (covers, wire grids, litter exclosure, open) were tested in terms of their efficiency in capturing ground-dwelling arthropods (Acari, Araneae, Carabidae, Formicidae, Isopoda, Myriapoda, Opiliones) in order to gain a better understanding of the applicability and reliability of pitfall traps in forests. Pitfall traps set in forests are usually protected with covers or wire grids, but the effect of these constructions on sampling efficiency as well as their practicability and necessity have so far received little attention. Capture efficiency of pitfall traps may be affected by external factors and the design of the trap. 12, 12165 Berlin, Germany e-mail: trapping is an approved self-sampling method for capturing epigeal arthropods for ecological and faunistic studies. 111 (1): 69-74, 2014 | DOI: 10.14411/eje.2014.008 The efficiency of pitfall traps as a method of sampling epigeal arthropods in litter rich forest habitats Johanna SIEWERS 1, Jens SCHIRMEL 2, Sascha BUCHHOLZ *,3 1īiological Station Wesel, Freybergweg 9, 46483 Wesel, Germany e-mail: 2Įcosystem Analysis, Institute of Environmental Science, University of Koblenz-Landau, Fortstraße 7, 76829 Landau, Germany e-mail: 3ĭepartment of Ecology, TU Berlin, Rothenburgstr. ![]()
