An experimental evaluation of self-interference in Narcissus assoanus: functional and evolutionary implications.
Floral traits that reduce self-pollination in hermaphroditic plants have usually been interpreted as mechanisms that limit the genetic consequences of self-fertilization. However, the avoidance of sexual conflict between female and male function (self-interference) may also represent an important selection pressure for the evolution of floral traits, particularly in self-incompatible species. H...
متن کاملIn the right place at the right time: Parnassia resolves the herkogamy dilemma by accurate repositioning of stamens and stigmas.
BACKGROUND AND AIMS Spatial (herkogamy) and temporal (dichogamy) separation of pollen presentation and stigma receptivity have been interpreted as reducing interference between male and female functions in hermaphroditic flowers. However, spatial separation leads to a potential conflict: reduced pollination accuracy, where pollen may be placed in a location on the pollinator different from the ...
متن کاملDo Abstinence-Plus Interventions Reduce Sexual Risk Behavior among Youth?
Perspectives A bstinence until marriage has emerged as a primary policy goal in efforts to promote adolescent sexual and reproductive health—in the United States and increasingly worldwide. While few would argue with abstinence as a personal choice (no one should be forced to have sex), there are serious questions about whether government promotion of abstinence should be a public health goal. ...

Reciprocal herkogamy promotes disassortative mating in a distylous species with intramorph compatibility.
Mating patterns in heterostylous species with intramorph compatibility have the potential to deviate from symmetrical disassortative mating owing to ecological and reproductive factors influencing pollen dispersal. Here, we investigate potential and realized patterns of mating in distylous Luculia pinceana (Rubiaceae), a species with intramorph compatibility. Our analysis provides an opportunit...
