Altered gene co-expression patterns in anthropogenic compared to wild habitats. a Gene expression correlation matrices (Pearson, r) were significantly different in wild and mesocosm fishes (Jennrich test, P = 6.89 × 10⁻¹³) but also retained similar structure (Mantel test, P = 0.001). b Scatter of pair-wise correlation coefficients for mesocosm and wild fishes: the wild coefficients explain 27 % of the variation in mesocosm coefficients in a linear regression. c Gene co-expression networks for wild and fishes constructed using the ARACNe algorithm, and the intersection of these networks showing shared edges (shared statistical associations between genes)
