Racing cane toads reveals they get cold feet on Southern Australia invasion
weren't allowed to compete in the Olympics, but scientists have raced cane toads
in the laboratory and calculated that they would not be able to invade Melbourne, Adelaide or Hobart and are unlikely to do well in Perth or Sydney, even with climate change.

Invasion of the cane toads
Why do some invasive species expand rapidly in a new environment while others do not" Scientists from the United States and Australia are beginning to make headway on this question after analyzing how fast cane toads
invaded different regions of Australia.
