The introduction of species into new environments has increasingly become an economically costly and environmentally destructive phenomenon. By integrating an understanding of ecology, behavior and genetics, we aim to develop a more quantitative understanding of biological invasions. Research topics currently under investigation include efforts (1) to quantify the factors controlling susceptibility to invasion, (2) to uncover the mechanisms involved in the displacement of native species, and (3) to determine how mutualistic interactions between invaders and other organisms disrupt existing mutualisms and contribute to invasion success.
