Figure legends:
Figure 1: Factors that predict DNMT1, DNMT3 and TET2 gene expression in house sparrows from across the globe. Visual summary of fixed-effects estimates from model selection results presented in Table 2.
Figure 2: Correlations in gene expression levels (log10 transformed) for DNMT1, DNMT3 and TET2: A) across countries, B) among-individuals, and C) within-individuals (i.e., residual correlations). The dotted vertical line denotes a correlation of zero (i.e., no correlation). Points are estimates derived from the MCMCglmm model output, and whiskers denote 95% CI. 95% CI that overlap zero are interpreted as not significantly different from zero.
