Abstract Preventing the introduction of potentially
invasive species is becoming more important as this worldwide problem continues
to grow. The ability to predict the identity or range of potential invaders
could influence regulatory decisions and help to optimally allocate resources
to deal with ongoing invasions. One screening tool presented here, using
species life history and environmental tolerances to identify potential invaders
similar to past invaders, can be used to predict potential invading species.
Another screening tool, genetic algorithms, can be used to predict the potential
range of an invading species. Use and further development of tools such as
these, that are quantitative and relatively transparent, would give managers
and other decision makers more information for making better-informed decisions.
