Figure 5From: Sensory trait variation in an echolocating bat suggests roles for both selection and plasticityEstimated migration patterns among populations of Cape horseshoe bats. The thickness of the arrows indicates the relative migration rates; values indicate M, the number of immigrants per generation scaled by mutation rate. The 95% confidence intervals are provided in Additional file 6: Table S3. Inset: Voronoi tessellation showing the assignment of populations to four spatially defined genetic clusters. A key to acronyms used are given in Table 1.Back to article page
