Intraspecific variation in seed dispersal between annual and perennial populations

Seed dispersal impacts plant fitness by shaping the habitat and distribution of offspring, influencing population dynamics and spatial genetic diversity. Whether the evolution of dispersal strategies varies across herbaceous life forms (annual, perennial, clonal) is inconclusive. This study examines how seed dispersal strategies vary between annual and perennial populations of Mimulus guttatus (syn. Erythranthe guttata), investigating differences in seedpod orientation and shape, and the probability and distance of seed dispersal.
