Pitfall Trap sampling bias depends on body mass temperature and Trap number insights from an individual based model
Ecosphere, 2017Co-Authors: Jan Engel, Lionel R Hertzog, Julia Tiede, Cameron Wagg, Anne Ebeling, Heiko Briesen, Wolfgang W. WeisserAbstract:The diversity and community composition of ground arthropods is routinely analyzed by Pitfall Trap sampling, which is a cost- and time-effective method to gather large numbers of replicates but also known to generate data that are biased by species-specific differences in locomotory activity. Previous studies have looked at factors that influence the sampling bias. These studies, however, were limited to one or few species and did rarely quantify how the species-specific sampling bias shapes community-level diversity metrics. In this study, we systematically quantify the species-specific and community-level sampling bias with an allometric individual-based model that simulates movement and Pitfall sampling of 10 generic ground arthropod species differing in body mass. We perform multiple simulation experiments covering different scenarios of Pitfall Trap number, spatial Trap arrangement, temperature, and population density. We show that the sampling bias decreased strongly with increasing body mass, temperature, and Pitfall Trap number, while population density had no effect and Trap arrangement only had little effect. The average movement speed of a species in the field integrates body mass and temperature effects and could be used to derive reliable estimates of absolute species abundance. We demonstrate how unbiased relative species abundance can be derived using correction factors that need only information on species body mass. We find that community-level diversity metrics are sensitive to the particular community structure, namely the relation between body mass and relative abundance across species. Generally, Pitfall Trap sampling flattens the rank-abundance distribution and leads to overestimations of ground arthropod Shannon diversity. We conclude that the correction of the species-specific Pitfall Trap sampling bias is necessary for the reliability of conclusions drawn from ground arthropod field studies. We propose bias correction is a manageable task using either body mass to derive unbiased relative abundance or the average speed to derive reliable estimates of absolute abundance from Pitfall Trap sampling.

Effect of Pitfall Trap type and diameter on vertebrate by-catches and ground beetle (Coleoptera: Carabidae) and spider (Araneae) sampling
Methods in Ecology and Evolution, 2010Co-Authors: Markus Lange, Martin M. Gossner, Wolfgang W. WeisserAbstract:Summary 1. To determine the diversity of epigaeic arthropods, Pitfall Traps are a suitable and widely accepted sampling method. Unfortunately small mammals such as shrews, voles and mice are accidentally caught by these Traps, sometimes very frequently depending on Trap type and size. 2. Here we present an experiment examining the influence of Trap types, conventional cup Traps vs. funnel Traps, and of Trap diameter on catches of carabid beetles, spiders and unwanted by-catches of small mammals. 3. The number of sampled carabid beetles increased significantly with diameter of the Traps and presence of a funnel. The number of species was not affected by Trap type or Trap size. 4. For spiders, significantly more individuals and more species were found in larger Traps. After correcting for difference in sample size by rarefaction, spider species number was still higher in larger Traps. The use of a funnel had no effect on spider assemblages. 5. Funnel Traps and a smaller Trap diameter strongly reduced catches of small mammals, on average by at least 2/3. While catches of arthropods increased with increasing Trap size independent of Trap type, the number of small mammals caught in the Traps was not greater in larger Traps when a funnel was used. 6. Based on our results and other studies on the efficiency of different Pitfall Trap types, we recommend to use funnel Traps of larger diameter (approximately 9 cm) to more efficiently sample epigaeic arthropod assemblages and to minimize unwanted catches of small mammals.
