Invasion Impacts

We know very little about what makes some exotic populations invasive (harmful) and others not.

To a great extent, the interest in biological invasions is generated from the sometimes profound impacts exotic species have on native species and ecosystems. Despite this understanding, we know very little about what makes some exotic populations invasive (harmful) and others not. We also have an inadequate understanding of how to efficiently and effectively detect, eradicate, and control known invasive species. We use simulation models to explore general principles related to the trade-offs associated with expending effort to detect, eradicate, or control invasive species relative to the likelihood of successfully reaching management goals.
