Figure 3

Genetic structure and number of migrants at the junction of Schwarzach (left), Kalserbach (right) and Isel (center) along the rivers (blue lines). The four genotype groups are represented in different colours (red, orange, yellow and brown) and number of immigrants from a source upstream (dark blue) and downstream (light blue) are shown in circles. Although two sites (one at Schwarzach and one at Kalserbach) are separated from the next source population upstream by canyons (grey blocks), they show immigrants from upstream. Geographically close populations next to the inlet of Kalserbach all show migrants from downstream sites.
