One genotype dominates a facultatively outcrossing plant invasion
Plant invasions are rarely homogenous. Processes such as selection, drift, gene flow, and founding events can rapidly shape the genetic diversity and...

Outcrossing rates in a rare “ornithophilous” aloe are correlated with bee visitation
Pollinator taxa may vary in their contribution to plant outcrossing rates and hence differ in their influence on plant fitness. In plants that have...

Self-fertilization does not lead to inbreeding depression in Typha parent species or hybrids
Some of the most impactful invasive plants are hybrids that exhibit heterosis and outperform their parent species. Heterosis can result from multiple...
