This file offers the data behind Fig. 4A-C of Lähteenmäki et al., estimating the effects of time, grazing regime (i.e. of grass length) and beetle taxa present on dung pat weight in the temperate experiment (for an in-depth description, see Appendix 1, section Experimental design, Finland). The specific columns are the following: BlockID: block identity CageID: cage identity Pat: dung pat replicate Grass height: simulated grazing regime, with L identifying long grass and S identifying short grass Geotrupes presence: design variable indicating whether Geotrupes was present or not Aphodius presence: design variable whether Aphodius was present or not Measurement: measurement day (treated as a categorical variable) Weight: dung weight, in grams
