Population responses to wild-derived and wild mouse urine stimuli. a, b Mean responses across the population for stimuli including wild-derived (A: stimulus set 2, n = 263) and wild (B: stimulus set 3, n = 241) mouse stimuli. Horizontal lines represent significant differences among stimulus pairs using a one-way non-parametric ANOVA (Kruskal-Wallis test). Broken lines indicate p values below 0.05, while solid lines indicate p values below 0.01. See Additional File 2 for specific p values for this and all other pairwise comparisons. c, d Pairwise correlation distance matrices of population responses for stimulus set 2 (c), and 3 (d). e, f Hierarchical clustering trees using correlation distances for stimulus set 2 (e) and 3 (f). g, h Distance representation using multidimensional scaling for stimulus set 2 (g) and set 3 (h). Units are arbitrary, but in each plot, axes are scaled equally
