Continuous variation in herkogamy in Mediterranean honeysuckle populations

Herkogamy, the spatial separation of sex organs in hermaphroditic plants, is thought to have evolved to reduce self-pollination and inbreeding within a...

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...

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...

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,...

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...

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
