FIG. C1. Changes in the frequency of Gilia plants along experimental transects in the Calcium Seep population. Five transects were established along the oak canopy boundary (shown on the left of the figure); another five were placed near the valley bottom boundary. Black dots indicate transect locations at which paired transplant plots were established. Gilia frequency indicates the percentage of quadrat points where plants were found.
