* Evaluate invader impacts at population and community levels, including underlying mechanisms. * Examine interactive impacts of drought and herbivory by biological control agents on the competitive dominance of a notorious weed. * Assess a new technique for assessing habitat quality for songbirds based on local song structure. * Measure effects of invasive plant control treatments on plants and animals and evaluate degree to which such methods mitigate target invader impacts.
My primary interest lies in building understandings of ecological patterns and processes in order to improve the management of natural systems. Current applications include evaluating impacts of exotic plants on native plants, cascading effects on consumers, and efficacy of weed control efforts in mitigating these impacts. Studies consider population and community level attributes, and organisms from plants and invertebrate to birds and their predators.
My past research includes examination of disturbance effects on harbor seals, edge effects of forest roads on songbirds, and habitat use of Canada lynx.
My work aims to develop and apply ecological principles to solve real-world problems facing managers of natural systems.
