Australian Rabbits

Caption: Rabbits crowded around a watering hole in southern Australia in 1938. This invasive species started with 24 individuals, reaching a population of 600 million by 1950 in part because of a phenomenon known as the Allee effect. A Duke University team has experimentally tested the concept in engineered bacteria.
