Fig. 3

The four sampling localities in eastern Tennessee are shown with orange stars (a), and the total number of nests collected that were either solitary (blue) or social (green) are shown with pie charts. The distribution of latency to move after perturbation (a measure of boldness) is shown for individuals from each of the four populations (b: Melton Lake, c: Melton Hill, d: Boone Lake, and e: Chilhowee Dam). Individuals that moved quickly (low latency score) are bold, whereas individuals with a slow response (high latency score) are shy. There was no association between nest type (social or solitary) and boldness; populations differed in the frequency of the alternate allele at the locus that is most strongly associated with boldness
