Study on Fruit Flies, Extinction Featured by CBC News


Prof. Ryan Norris

Integrative biology professor Ryan Norris discussed his most recent study with CBC News. His research team looked at how fear of predators pushes some species toward extinction. Based on their study, which exposed fruit fly populations to the scent of a praying mantis, Norris said the lingering smell of a predator is enough to cause a vulnerable population to decline. He studies animal behaviour, conservation and population ecology.
