Both biotic (e.g. pollinators, herbivores) and abiotic ecological factors (e.g. soil, temperature) cause selection and thus impact adaptive evolution in plants. Nevertheless, we know little about the impact of individual factors and their interactions, as well as the speed of evolutionary adaptation, because of the paucity of controlled experimental studies addressing these questions in plants...
Floral scents function as both long- and short-distance cues, conveying information about a plant’s presence, identity, and resource availability. The success of plant–pollinator interactions depends critically on pollinators’ responses to these volatile organic compounds (VOCs). A central feature of floral scent is its evolutionary lability: in this tight retroaction cycle, emission of and...
