Description of Research

The research in my laboratory focuses primarily on the ecology of invasive plant species and their biological control using insects and pathogens. With support from NSF, USDA, and other sources, I have pursued a comprehensive program linking field observations, experiments, and mathematical modeling to test assumptions and predictions of ecological theories applied to biological invasions and biological pest control.  In addition, I maintain a broad interest in population and community ecology and am involved in studies of plant population dynamics; ecology and evolution of plant life history features (dispersal, dormancy, perenniality, iteroparity); and host-plant selection by insects.  I have worked closely with Eric Coombs (Oregon Department of Agriculture) and others to develop and implement biological control programs on state, regional, and national scales.   My work extends to public policy issues surrounding invasions and release of new organisms into the environment, as reflected in studies conducted for the U.S. Congress Office of Technology Assessment (OTA), the National Research Council (NRC), and other government and non-government organizations.

My research focuses on understanding the ecological risk of the cinnabar moth to non-target host plant arrowleaf groundsel (Senecio triangularis). In addition to analyzing long-term regional datasets for these two species, I am also conducting an experiment in the Willamette National Forest to determine how sensitive this non-target plant is to herbivory by cinnabar moth larvae at different timing and intensities.

I currently study rapid adaptation of the cinnabar moth to host plant and climate. Using field, greenhouse and lab studies I investigate changes in preference and performance of the moth larvae and adults towards the target (J. vulgaris, ragwort) and non-target (S. triangularis) host plants; and changes in performance under a mountain or valley climate. I’m also interested in knowing more about the speed of adaptation through (natural) selection experiments and comparing climate adaptation in populations along similar elevation gradients (regionally and abroad, including in my home country, Switzerland).
