Effect sizes by LTI type and trophic level for insect abundance (mean and 95% confidence intervals). A mean value above the dashed zero line indicates that the abundance is higher in verges than in compared habitats. Values in grey above LTI types indicate the number of study cases/number of studies for each trophic level. *p < 0.05, ***p < 0.001
