In 1935, cane toads were first introduced to Australia from Hawaii as a biocontrol agent. The toads were meant to replace the use of toxic pesticides to reduce the native cane beetle population that was decimating sugar cane, a valuable Australian crop. Since their release, however, cane toads have rapidly multiplied: over 70 years, the population increased from 100 individuals to over 200 million! The toads have devastated local ecosystems, including spreading diseases to native wildlife, preying on native fauna, and out-competing native insectivores for food. Additionally, no evidence has been found that they have had any effect on the cane beetles that they were meant to control. What type of growth model does the cane toad population follow?
