Differences in the sum of all significantly regulated transcripts of Hyas araneus after exposure experiments. For each treatment, up- and down-regulated transcripts were counted and represented as bars (black bars = up-regulated; grey bars = down-regulated). Treatments were tested for statistical differences using the Wilcoxon signed rank test (p < 0.05). Letters denote the significant differences. Differing letters indicate significant differences; identical letters indicate no significant difference.
