Science and management

Biological invasions are well recognized a leading threat to the structure and function of ecosystems. Our research aims to advance the science, management and policy of invasive species with the goal of providing information on ecological impacts, elucidating introduction pathways and weighing the costs and benefits of considering prevention versus mitigation strategies for existing or...

Effects of multiple stressors

The conjunction of invasive species with climate change and increasing agricultural and urban land-use threaten the functioning of freshwater ecosystems. Resource managers, scientists and policy makers are becoming increasingly cognizant that the future will bring simultaneous changes in these factors, but lack the science and decision-support tools required to develop management strategies that...

Fair and balanced perspectives

Although non-native species are often anathema to people who care about the environment, emerging evidence suggests that beneficial invaders occur at times. Ecosystem services provided by non-native species go beyond agriculturally important species, and include providing food and habitat for native species and substituting functionally for species that have gone extinct. Our research continues...
