Figure 4.

Morphological variation in Cyprinella lutrensis along the habitat divergence vector. Grids are thin-plate spline transformations from specimen means along the morphological divergence vector at the observed scale. Lines are drawn between landmarks to aid visualization. Landmark vectors below transformations reflect the direction and magnitude of each landmark movement between habitats. Vectors point in the direction landmarks moved from stream habitats to reservoir habitats. The top visualization is at the observed range and the bottom is magnified 3×.
