In many angiosperm species, populations are reproductively subdivided into distinct sexual
morphs including females, males and hermaphrodites. Sexual polymorphism is maintained …

The aquatic perennial herb Sagittaria trifolia L. commonly known as arrowhead, has been
utilized in China both as a culinary vegetable and in traditional medicines. Characterizing …

Many plants express their female and male sex roles at different times (dichogamy), with
important consequences for mating. Dichogamy can yield mate limitation via biased floral …

Clonality is often implicated in models of the evolution of dioecy, but few studies have
explicitly compared clonal structure between plant sexual systems, or between the sexes in …

The spatial genetic structure (SGS) of plant populations is determined by the outcome of key
ecological processes, including pollen and seed dispersal, the intensity of local resource …

Investment in male function should often yield diminishing fitness returns, subjecting the
evolution of male phenotypes to substantial constraints. In plants, the subdivision of male …

The stable coexistence within populations of females, males, and hermaphrodites
(subdioecy) is enigmatic because theoretical models indicate that maintenance of this …

Indirect measures of sexual selection have been criticized because they can overestimate
the magnitude of selection. In particular, they do not account for the degree to which mating …

Sagittaria natans (Alismataceae) is an endangered aquatic herb in China. The nuclear
microsatellite (SSR) loci variation of the 11 extant populations of S. natans was investigated …

Habitat fragmentation and population declines have led to increased population edges,
exposing higher proportions of plants to ecotones. However, it remains a challenging …
