Current Research

My research focuses on understanding the circumstances in which anthropogenic impacts (e.g., roads, dams) affect wildlife populations. I’m particularly interested in determining which species or species groups are most vulnerable to human impacts and determining ways to mitigate negative effects. Most recently, my research has focused on two themes: (1) determining ways to improve knowledge on the influence of mitigation measures on wildlife populations through experiments, and (2) using evidence synthesis to inform management/policy/funding decisions. I’m currently working with Dr. Steven Cooke and Dr. Joseph Bennett with the Canadian Centre for Evidence-Based Conservation involved with conducting evidence synthesis and meta-analysis on a variety of topics including, for example: the effectiveness of counter-wildlife crime interventions for conserving wildlife directly threated by exploitation, the impacts of flow regime changes on fish productivity in temperate regions, the consequences of fish entrainment and impingement associated with hydroelectric dams on fish productivity, the effectiveness of captive breeding programs for freshwater species as risk fish and mussels at achieving conservation targets, and the performance of fish passage facilities and culverts for promoting fish movement at barriers.
