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

The harmful effects of close inbreeding have been noticed for many centuries (34, 35, 165).
With the rise of Mendelian genetics, it was realized that the main genetic consequence of …

Considerable effort has been spent documenting correlations between dioecy and various
ecological and morphological traits for the purpose of testing hypotheses about conditions …

Dichogamy is the separation of the presentation of pollen and stigmas in time within a plant.
It is a common but neglected feature of outcrossing angiosperms. Dichogamy has been …

Background The rich literature that characterizes the field of pollination biology has focused
largely on animal-pollinated plants. At least 10% of angiosperms are wind pollinated, and …

This chapter is divided into two sections, the first dealing with the evolution of dispersal
mechanisms and the second with the consequences of dispersal at population and …

Pseudocereals are promising crops for coming decades keeping in view the global food
security. Amaranths are a leading group of plants among the pseudocereals that have the …

The order Poales comprises a substantial portion of plant life (7% of all angiosperms and
33% of monocots) and includes taxa of enormous economic and ecological significance …

▪ Abstract Examples of androdioecy, the coexistence of males and hermaphrodites, was
unknown when the subject was last reviewed about two decades ago. Since then, several …

Two sex-differential selective forces which have hitherto been principally applied to the
evolution of unisexuality are postulated to affect the disposition of pollen grains and stigmas …
