Contains data used in the following publication: Felix Neff, Jonas Hagge, Rafael Achury, Didem Ambarlı, Christian Ammer, Peter Schall, Sebastian Seibold, Michael Staab, Wolfgang W. Weisser, Martin M. Gossner (2022). Hierarchical trait filtering at different spatial scales determines beetle assemblages in deadwood. Functional Ecology. https://doi.org/10.1111/1365-2435.14186 These are complementary data, which are needed to reproduce the analyses. Most data are archived in the Biodiversity Exploratories Information System (https://doi.org/10.17616/R32P9Q). The following data are included: BELongDead_Subplots_Normal.csv: List of normal subplots within the BELongDead projects (only these were included in the analyses) Body_length.csv: Body length data for study species assembled from Freude et al. (1965-1998) Lightness_completion.csv: Colour lightness recorded from measured individuals and photos from coleonet.de (Lompe, 2002) Name_standardisation.csv: Dataset used to standardise taxonomic names from different sources Saproxylic_species_sub.csv: List of saproxylic species (according to Schmidl & Bussler (2004)), which were recorded in the project Similar_Species.csv: List of similar species for species with missing traits. Based on these, missing traits were estimated References Freude, H., Harde, K. W., & Lohse, G. A. (1965–1998). Die Käfer Mitteleuropas Band 1-15. Goecke und Evers. Lompe, A. (2002).
