Sex ratio variation in Fragaria chiloensis.

Fragaria chiloensis displays a pattern of decreasing female frequency with latitude from California to northern Washington — a pattern similar to other dioecious species. Skewed sex ratios in dioecious plants are primarily the result of differential survivorship between sexes. Previous work has shown sex specific differences in clonal reproduction (runnering) are consistent across sites in California. However, no study has examined the variations in life history and demography across the geographic range of F. chiloensis.
