Professor Robert Pringle and his co-authors used cameras to document the zest with which wild African browsers will eat the invasive Sodom Apple (S. campylacanthum). Pringle worked with Corina Tarnita, a Princeton mathematical biologist and assistant professor of ecology and evolutionary biology, as well as with collaborators from the University of Wyoming, the University of Florida, the University of California-Davis, the Mpala Center and the University of British Columbia.
The researchers specifically observed the foraging activity of elephants, impalas, small-dog-sized antelopes known as dik-diks, and rodents. They captured about 30,000 hours of foraging using cameras they had focused on particular plants. The researchers also marked several hundred Sodom-apple fruit to track how many were eaten, and measured the average height, mortality and reproducibility of Sodom-apple plants in all the exclosures.
