Title: Effects of noise on predator-prey relationships in a marine ecosystem
Abstract: Anthropogenic noise has become a prominent source of disturbance in our oceans. Among other things, it affects the behavior of many marine organisms. Changes in predation behaviors – both of the predator and the prey – can have direct fitness effects and affect multiple species at the same time. During my PhD, I investigated how foraging and antipredator behavior was affected by noise in harbor porpoises and their prey, sand gobies. By using an experimental approach, I was able to investigate how different characteristics of the sound exposure could influence this vital interaction between species.
