Personal Development Associate Professor Clare McArthur, from the School of Life and Environmental Sciences at the University of Sydney, explains the implications of research linked to different personalities in possum foraging. In this latest research on possums, personality, plants, poisons and primary parasites all play a part. The studies follow on from experimental work a few years ago that showed personality, laid on top of predation risk and plant toxins, explained variations in how individual possums forage. The latest research looked at how possums used their environment, what food they ate in their natural world and how personality affected this.
