Fig. 3. Percentage of reads attributed to carabid, prey and other for Nebria salina and Poecilus cupreus for samples from 2013 to 2019 and 2021. Colors distinguish between (a) prey reads (green), (b) carabid reads (blue) and (c) other reads (contaminants and not assigned – orange). Proportions are given as percentages of the total number per sample (after filtering the singletons).
Fig. 5. Prey diversity in the diet of Nebria salina (a) and Poecilus cupreus (b) through time. Each dot represents the diet of one carabid specimens, dots are jittered horizontally and vertically for more clarity. The curve corresponds to a linear regression with the grey area displaying the 95 % confidence interval.
