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 …

Species diversity is remarkably unevenly distributed among flowering plant lineages.
Despite a growing toolbox of research methods, the reasons underlying this patchy pattern …

Despite the prevalence of sexual reproduction across eukaryotes, there is a remarkable
diversity of sex‐determination mechanisms. The underlying causes of this diversity remain …

Abstract About 15,000 angiosperm species (∼ 6%) have separate sexes, a phenomenon
known as dioecy. Why dioecious taxa are so rare is still an open question. Early work …

Angiosperm sexual systems are fundamental to the evolution and distribution of plant
diversity, yet spatiotemporal patterns in angiosperm sexual systems and their drivers remain …

Variation in species richness across the tree of life, accompanied by the incredible variety of
ecological and morphological characteristics found in nature, has inspired many studies to …

Sexual system is a key determinant of genetic variation and reproductive success, affecting
evolution within populations and within clades. Much research in plants has focused on …

Inferring the geographic mode of speciation could help reveal the evolutionary and
ecological mechanisms that underlie the generation of biodiversity. Comparative methods …

Abstract Background and Aims Although dioecy, which characterizes only 6% of angiosperm
species, has been considered an evolutionary dead end, recent studies have demonstrated …

Population divergence is the first step in allopatric speciation, as has long been recognized
in both theoretical models of speciation and empirical explorations of natural systems. All …
