Understanding plant population, community, and invasion dynamics
Research in my group examines leading questions at the interface of plant population and community ecology. Though I am primarily an empirical ecologist, the approaches we take often have population models at their core, allowing rigorous links between theoretical concepts and the dynamics of plants in their natural environment. Over the last ten years, our research has focused on two primary themes: (1) the maintenance of species diversity and (2) the controls over the spread and impact of biological invasions.
Our projects have explored all stages of the invasion process, from introduction through impact. Current work examines the movement of invasive plants across landscapes, and how habitat fragmentation influences invader spread and native plant persistence. This work combines mathematical models with empirical approaches involving Arabidopsis, an experimental system in which the ecological and evolutionary controls over invader spread can be teased apart. Our research into the maintenance of biodiversity combines experiments and models to explore the role of niche differences between species in regulating their coexistence. Recent work in this area explores how ecological drift, genetic diversity and natural selection influence the outcome of plant interactions.
