Biological invasions are gaining attention as a major threat to biodiversity and an
important element of global change. Recent research indicates that other components
of global change, such as increases in nitrogen deposition and atmospheric CO2 concentration,
favor groups of species that share certain physiological or life history traits. New
evidence suggests that many invasive species share traits that will allow them to
capitalize on the various elements of global change. Increases in the prevalence of
some of these biological invaders would alter basic ecosystem properties in ways that
feed back to affect many components of global change.
