Biological invasions are one of the strongest drivers of global environmental change, and invasive species are now often in the public discourse. At the same time, economists have begun to take a real interest in determining how invasive species interact with economic systems, and how invaders should be controlled to optimize societal wealth. Although the work from ecologists and economists have both greatly expanded our understanding of the drivers and impacts of invasions, little integration between the fields has occurred that would allow managers and policy-makers to identify the optical...

Over the past several decades, the field of invasion biology has rapidly expanded as global trade and the spread of human populations have increasingly carried animal and plant species across natural barriers that have kept them ecologically separated for millions of years. Because some of these nonnative species thrive in their new homes and harm environments, economies, and human health, the prevention and management of invasive species has become a major policy goal from local to international levels.

Yet even though ecological research has led to public conversation and policy...
