How do sampling methods impact our understanding of mating system distribution in angiosperms?

Plant mating systems are key determinants of fitness. Angiosperms exhibit a diversity of reproductive strategies, including self-fertilization (or selfing), outcrossing, and mixed mating. It has been estimated that up to 43% of plant species are capable of selfing, and that selfing may provide reproductive assurance in marginal conditions where opportunities for mating may be limited. However, the distribution of selfing rates across angiosperm species, and the overall prevalence of mixed mating remains an active area of debate. Here, we discuss the distribution of selfing rate in flowering plants, and utilize non-parametric methods to examine how previous sampling methods may have impacted our present understanding of the prevalence and distribution of selfing and mixed mating. Data on plant mating systems, such as quantifications of selfing rates, may be profoundly biased due to increased interest in species that exhibit mixed mating and selfing. By examining the potential for systematic study bias, we can further understand the diversity of plant reproductive systems and their implications for botanical diversity.
