Title

Reproductive Assurance Among Populations of the American Bellflower

Abstract

Reproductive assurance is the ability to self-fertilize when little or no outcrossing is available. In certain plant species, it is an adaptive mechanism that allows plants to reproduce in habitats that would otherwise be unsuitable given their lack of pollinators. The American Bellflower (Campanula americana) is a beautiful woodland herb with a wide distribution in the eastern United States. It has a mixed mating system, meaning that an individual plant both self-fertilizes and out-crosses via pollinators. Interestingly, C. americana populations at one end of the geographic range tend to self-fertilize more than plants in the rest of the range, a sign that reproductive assurance may be occurring in certain range-edge populations. Through intensive field and lab work that involved pollinator surveys, measurements of several floral traits, and seIfing rate measurements, we aimed to determine if and how these plants exhibit reproductive assurance.
