Variability in bumblebee pollination buzzes affects the quantity of pollen released from flowers
Buzz-pollination is a plant strategy that promotes gamete transfer by requiring a pollinator, typically bees (Hymenoptera: Apoidea), to vibrate a flower’s anthers in order to extract pollen. AlthoughExpand

Division of labour within flowers: heteranthery, a floral strategy to reconcile contrasting pollen fates
In many nectarless flowering plants, pollen serves as both the carrier of male gametes and as food for pollinators. This can generate an evolutionary conflict if the use of pollen as food byExpand

Comparison of pollination and defensive buzzes in bumblebees indicates species-specific and context-dependent vibrations
Bees produce vibrations in many contexts, including for defense and while foraging. Buzz pollination is a unique foraging behavior in which bees vibrate the anthers of flowers to eject pollen whichExpand

Modification of flower architecture during early stages in the evolution of self-fertilization.
BACKGROUND AND AIMS The evolution of selfing from outcrossing is characterized by a series of morphological changes to flowers culminating in the selfing syndrome. However, which morphological traitsExpand

Floral vibrations by buzz-pollinating bees achieve higher frequency, velocity and acceleration than flight and defence vibrations
Vibrations play an important role in insect behaviour. In bees, vibrations are used in a variety of contexts including communication, as a warning signal to deter predators and during pollenExpand

Bee and floral traits affect the characteristics of the vibrations experienced by flowers during buzz-pollination
During buzz pollination, bees use their indirect flight muscles to produce vibrations that are transmitted to the flowers and result in pollen release. Although buzz pollination has been known forExpand

Revealed: the first ever flower, 140m years ago, looked like a magnolia
Although most species of plants on Earth have flowers, the evolutionary origin of flowers themselves are shrouded in mystery. Flowers are the sexual organs of more than 360,000 species of plantsExpand
