Fig. 3From: Population structure and insecticide response of Gammarus spp. in agricultural and upstream forested sites of small streamsMinimum spanning network created from Gammarus fossarum CO1 sequences using the pegas package 1.1–2 [84]. The circles represent sampled haplotypes (H1–H15) and their dimensions are scaled based on the number of sequences given in Additional file 1: Table S9 and 10. Short vertical lines on the connecting lines between haplotypes represent mutations. Colours represent site typesBack to article page
