Enantiostyly, a reproductive system characterized by heteromorphic flowers with either left or right style deflection, compels reciprocal pollen transfer between floral types. The potential outcrossing advantage of...

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...
Foraging responses of bumblebees to rewardless floral patches: Importance of within-plant variance in nectar presentation
Nectar-foraging pollinators respond flexibly to the reward condition of floral patches. In a new study published in AoB PLANTS, Nakamura and Kudo compared foraging behaviours of bumblebees between naturally rewarding...

Maintenance of self-incompatibility in peripheral populations of a circumboreal woodland subshrub
Compared with self-incompatible (SI) species, species that shift to self-compatibility (SC) are more likely to colonize a new habitat. Linnaea borealis, named after Carl Linnaeus and commonly known as twinflower, is an...
Sterile flowers promote female reproductive success
Large floral displays attract pollinators but can also promote among-flower self-pollination (geitonogamy). Morales et al. assess the effects of the presence of sterile flowers and fertile-flower display size in...
