Episode 313: Fear itself

In the animal kingdom, the power of fear is something no one would question. Fear can impact and control entire populations, affect whole ecosystems, and even change the path of evolution. But is it something we can measure – and once and for all, prove that the role of predators is more than just what they eat?

A new study from Raincoast Conservation Foundation does just that. Led by Raincoast’s ecologist and PhD student Justin Suraci, the team of scientists showed through experiments that the mere presence of predators can impact the behaviour of mesopredators and other species further down the food chain.

By using the sound of dogs barking Suraci and his team validated that fear itself is indeed something to behold.

To talk more about this study, its real world applications, and what it could be mean in future policy planning, Defender Radio was joined by Raincoast’s Justin Suraci.
