Describtion of variables:

species = carabid beetles species, scientific names according to Müller-Motzfeld (2004).
cor_sum = bias-corrected (Engel et al. 2017) abundance for each species, summed up across all plots and years (EWcarabids1999-2022_rawdata.csv).
trend2 = species-specific trend in sampling abundance across all years and plots. Meaningfulness of trend was determined by comparing AIC to null model.
spei_eff2 = species-specific sensitivity of sampling abundance to the 72-month SPEI. Meaningfulness of effect was determined by comparing AIC to null model.
wings = hind wing development.Source: Homburg et al. (2014) / carabids.org
size = mean size (body length, mm) for each species. Source: Homburg et al. (2014) / carabids.org
latitude = latitudinal center of distribution range. Source: Homburg et al. (2014) / carabids.org
humidity_preference_SUSTEK = Preference for humidity (1=dry, 8=humid) according to Sustek (2004)
