Concentration–response relationship visualised for the mortality of Gammarus spp. individuals after 96 h of exposure to imidacloprid, visualised for the tested concentration range (A, B; test concentrations were log-transformed with half of the lowest non-zero test concentration added to avoid infinite numbers) and the relative abundance of Gammarus fossarum per site type (C). Each coloured dot represents the mean of replicates per concentration and sampling site (with different degrees of transparency for overlapping dots). The lines represent the average estimate of mortality per exposure concentration for a typical stream with the shadowed areas indicating the 95% confidence intervals (uncertainty of random effects not taken into account). Colours represent the site types (A, C) or the relative abundance of G. fossarum (B). Note that in A the line of the edge is slightly covered by the line of the refuge
