Summary: The proposal seeks to explore the role of hybridization in plant invasiveness through an interdisciplinary research at the interface between population genetics, remote sensing and ecology, using the model genus Carpobrotus (Aizoaceae) as an example. We will sample the three most invasive Carpobrotus species and their hybrids across their native and invaded ranges, and develop taxon-specific microsatellite markers to identify their distribution at global scale. Their spread over time will be reconstructed by using remote sensing techniques. The species identified in the field will be grown in a common garden, cross-pollinated, and their hybridization potential will be assessed using the developed microsatellite markers. Finally, the population characteristics of the species and hybrids identified in the field and those resulting from the cross-pollination experiments will be measured and used to determine the influence of hybridization on plant invasiveness. The results of this project will contribute to answering fundamental questions on the role of hybridization in plant invasions.
