The ecology and evolution of invasive plant species

Photograph of purple loosestrifeCombining ecological and genetic approaches, we have examined the process of biological invasion in three different plant systems. In multiflora rose (Rosa multiflora) we used genetic markers to quantify the relative contributions of sexual reproduction via seed versus vegetative reproduction via clonal spread to local patterns of invasion (Jesse et al. 2010). In purple loosestrife (Lythrum salicaria) we compared phenotypic plasticity of native European versus invasive North American populations in response to variation in water and nutrient levels (Chun et al. 2007).
