Figure 2. Food scarcity and ambient temperature affect gene expression in the posterior
and anterior hypothalamus. Relative gene expression levels of Tshβ, Tshr, Dio2, Kiss1 and
Rfrp3 in the posterior hypothalamus and Kiss1 and Gnrh in the anterior hypothalamus for (A,
E) common vole males, (B, F) common vole females, (C, G) tundra vole males and (D, H)
tundra vole females respectively, at low (open symbols) or high workload (filled symbols), at
10°C (blue) or 21°C (red). Data are presented as means ± SEM (n = 6-8). Significant effects
(two-way ANOVA) of workload (wl) and temperature (temp) are shown: *p < 0.05, **p <0.01,
***p < 0.001. Significant differences between groups (one-way ANOVA) are indicated by
asterisks. Statistic results for ANOVAs can be found in Table S4.
