A new species of toad is introduced into a region in a shipment of fruit, survives, and manages to start breeding. How could you determine whether the toad was an invasive species? You would need to determine whether it started breeding with native species. You would have to see if it was present over a large region or if it stayed in one location. All nonnative species are invasive species. You would need to watch over time to see if it had a negative effect on other species. As it is now breeding in the area, it would be considered native and not invasive.

EVOLUTION LINK Biologists have wondered how introduced species that would probably have limited genetic variation (due to the founder effect) survive and adapt so successfully that they become invasive. Part of the answer may be that invasive species are the result of multiple introductions instead of a single one. Explain how multiple introductions from a species native area to an introduced area could increase that species invasion success.

Figure 19.6 If the major food source of seals declines due to pollution or overfishing, which of the following would likely occur? a.

The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d. The carrying capacity of seals would remain the same, but the population of seals would decrease.
