I am interested in the management of pests and invasive species, especially by biological control. Using experimentation and modeling, I aim to understand the underlying ecology, demography and evolution of the species and species interactions involved. I collaborate with professionals and stakeholders to test and evaluate new management options.
Background: common ragweed (Ambrosia artemisiifolia) is one of the most prominent invasive alien plant species in Europe. Originating from North America, it has become a worldwide invader. It can cause crop yield reductions and its allergenic wind-dispersed pollen are a problem for human health. Common ragweed is expected to expand its range in Europe. Therefore, we need to understand the drivers of its success and to develop long-term management strategies.
My focus: i) Understanding spatio-temporal variation in the population dynamics of ragweed. I coordinate an international 3-year European-wide field survey on ragweed demography (http://ragweed.eu/task-forces/task-force-population-dynamics), and use the data to construct an environmental-dependent demographic model of ragweed.
ii) Assessing the potential for classical biological control of ragweed, a control method relatively new to Europe. I will assess the efficacy of the exotic leaf beetle Ophraella communa by experimentation in the field, and by modeling its impact on ragweed population dynamics.
The framework: this research is performed in the framework of the European COST Action SMARTER (www.ragweed.eu), which we coordinated from 2013 to 2016.
