Herkogamy, the spatial separation of sex organs in hermaphroditic plants, is thought to have evolved to reduce self-pollination and inbreeding within a population. Yet there has been little evidence to support these...

Mixed mating after the loss of self-incompatibility in a long-living perennial herb
Flowering plants display an extensive range of adaptive floral forms, which are often correlated with their mating systems. The maintenance of contrasting strategies such as those adopted by obligate outcrossers...

High male fertility in males of a subdioecious shrub
Female reproductive success in females versus hermaphrodites has been well documented. However, documenting a potential advantage in fertility of male versus hermaphrodite individuals in subdioecious species is also...

Effect of nectar robbing on a pollinator-dependent plant
Nectar robbing commonly has negative consequences for the reproductive success of plants. Because total plant fitness is the result of both female and male functions, Rojas-Nossa et al. studied the effect of nectar...
Pollinator limitation on reproductive success in Iris tuberosa
Variation in plant and floral size can have conflicting effects on pollination and fruit production in flowering plants. In a new study published in AoB PLANTS, Pellegrino measured the effect of varying pollinator...
Temporal variation in gender in an annual plant
The widespread tendency towards declining fruit set from first to last flowers on plants may contribute to temporal variation in allocation optima.
Ants mediate plant reproductive traits
The selection of floral and reproductive traits is influenced by the plant’s abiotic environment, florivores and pollinators. Leroy et al. show that mutualistic associations with ants can result in an enhanced...
