Abstract Context Evidence for declines in insect populations is growing with climate change being one suspected driver. Forests, however, are still underrepresented the relevant research. Recent droughts (2018–2020) have severely affected forests Central Europe and been linked to carabid abundance, biomass as well changes species traits at local scale. Objective We tested drought effects on forest carabids regional additionally investigated whether variability could be explained initial community composition environmental context. Methods used generalized linear mixed models compare data from 1999 2001 2020 2022 across eleven old beech sites of high conservation interest North-East Germany biomass, Hill numbers selected traits. then additional community-related predictors explain spatial biomass. Results found significant 65% abundance 51%. There were no numbers. consistent evidence that especially larger less mobile species. Declines also occurred strictly protected old-growth forests. Among predictors, landscape best stronger decline area their vicinity. Conclusions Our findings reveal large-scale context recent highlight exceptional role this regard. Future strategies need incorporate potential exposure extreme weather.
