Impacts reported for alien reptiles and amphibians, excluding species reported to affect
only other aliens. Only a few examples of taxa involved in loss of scientific understanding are

will be even truer if lag phenomena among the naturalized populations themselves
should prove common. So it seems likely that instances of ecological, evolutionary,
health, and economic impacts from herpetological introductions will multiply as
additional alien populations expand and become studied. This is further suggested
