The specialised buzz-pollination syndrome poses a partial barrier to plant invasions

We reviewed the literature on buzz-pollination of invasive plants to assess whether: (1) plant species exhibiting specialised pollination syndromes are underrepresented as invasive species, and (2) species with specialised pollination syndromes that have become invasive can reproduce in the absence of specialist buzzing pollinators.
We found 2.5% (117/4,630) of invasive angiosperms have poricidal anthers, which is an underrepresentation of the proportion of global angiosperms that are estimated to have poricidal anthers (6-10%). Most invasive buzz-pollinated plants are genetically self-compatible (97%), but only 43% can set fruit in the absence of a pollinator.
