The longer a plant waits to self-pollinate, the longer it has to attract pollen from outside. But waiting too long can have consequences.

Evolution of plant mating systems drives pollen limitation
Seed production of plants is rarely maximized, because it is limited by pollen receipt. Previous theories have shown that ecological mechanisms can drive the evolution of pollen limitation. Devaux et al.’s model shows...

Relative contribution of reproductive attributes to density-dependent effects on fruit-set
How much fruit can a plant set? Pollinator dependence and pollinator behaviour play a role, as does plant density.

Plant biotic interactions and fitness in habitat edges
Habitat variations influence the richness and composition of insect guilds. This affects plant reproduction, which depends upon functional relationships with insects involving both pollination and predation. The impact...

Unfavourable pollination environments promote evolution of a stable mixed reproductive system in angiosperms
Self-incompatible plants were less frequent in populations with consistently worse pollination environment, suggesting that reproductive assurance selects for selfing in these areas.

Inbreeding and stress in hemiparasites
Small and fragmented populations of hemiparasitic plants are dependent upon their host species and can be susceptible to inbreeding depression. In addition, they may also be strongly affected by a lack of suitable host...
Commonness, reproductive patterns and inbreeding depression of two Jumellea species
Population size reduction can threaten long-term persistence of plant populations through loss of genetic diversity and inbreeding depression. Blambert et al. evaluate the consequences of population size reduction by...
Pollinator decline, high pollen limitation and low progeny quality
Interactions between species are especially sensitive to environmental changes. The interaction between plants and pollinators is of particular interest given the potential current global decline in pollinators. Reduced...
Genetic diversity and mating system of autopolyploid Vicia
Polyploids may be better colonizers because they possess higher genetic diversity, and thus the ability to adapt to changing conditions.
How environmental stress from transplanting into foreign habitats influences inbreeding depression
Inbreeding depression does not increase in foreign environments: A field experimental study.
Why bother with females?
Gynodioecy (coexistence of females and hermaphrodites) occurs in numerous flowering plants, so understanding its maintenance has wide importance.
