Dioecy, the coexistence of separate male and female individuals in a population, is a rare
but phylogenetically widespread sexual system in flowering plants. While research has …

Dioecy, the presence of male and female flowers on separate individuals, is both
widespread and uncommon within flowering plants, with only a few percent of dioecious …

Evolutionary transitions from hermaphroditism to dioecy have been common in flowering
plants, 1, 2 but recent analysis also points to frequent reversions from dioecy to …

Dioecy has evolved independently, many times, among unrelated taxa. It also appears to
have evolved along two contrasting pathways:(1) from hermaphroditism via monoecy to …

Dioecy, the sexual system in which male and female organs are found in separate
individuals, allows greater specialization for sex‐specific functions and can be …

SS Mayer and D, Charlesworth ln some dioecious plant species, males and/or females have
large and presumably costly opposite-sex structures that are sterile. This is termed 'cryptic …

• Premise of the study: Separating sexual function between different individuals carries risks,
especially for sedentary organisms. Nevertheless, many land plants have unisexual …

In this chapter, I shall review theoretical models of the evolution of dioecy from
hermaphroditism. I hope to show why theoretical ideas have been important, and why we …

In several angiosperm genera distyly has evolved into dioecy. In every known case, male
plants are believed to have evolved from short-style and females from long-style plants. We …

A range of hypothesized evolutionary pathways has been proposed for describing the
evolution of dioecy. However, the evolutionary links between other sexual systems not …
