WebJan 10, 2024 · INTRODUCTION. The vast majority of flowering plants (~87.5%) are at least partly dependent on animals for pollen transfer (Ollerton et al., 2011).Therefore, pollination ecology has been shown to theoretically play an essential role in the evolution of selfing and the maintenance of mixed mating systems (Holsinger, 1991; Johnston, 1998; … WebThe evolution of plant mating systems has undoubtedly been linked to the evolution of traits that influence the type of pollination and pollinator attraction to flowers.

WebNov 22, 2011 · The influence of viability selection on mating system evolution has not been studied theoretically. We model plant mating system evolution when a single locus simultaneously affects the selfing rate, pollen export, and viability. We assume frequency-independent mating, so our model characterizes prior selfing.
