Intraspecific variation of scent and its impact on pollinators' preferences.

Floral scents shape plant-pollinator interactions. Although populations of the same species can vary in their floral scent, little is known about how this variation affects pollinator visitation. In this study, we compare the scents emitted by buzz-pollinated (Solanaceae) in two areas of its distribution (Mexico and USA) and investigate how these differences in scent affect pollinator preferences and attraction.

Changes in Reproductive Traits in ; An Unexpected Shift Toward Self-Incompatibility in a Domesticated Annual Fruit Crop.

Domestication is an evolutionary process with an impact on plant reproduction. Many domesticated plants are self-compatible (i.e.

Pollinator Preferences for Floral Volatiles Emitted by Dimorphic Anthers of a Buzz-Pollinated Herb.

Floral scents attract pollinators to plant rewards; in nectarless flowers, pollen grains are the only reward. Thus, pollen not only fertilizes ovules, but also feeds pollinators. This dilemma is resolved by specialization of anthers (i.
