During her PhD studies, Cara Alyse Gallagher developed a model of the metabolism of harbor porpoises for use in species management and conservation. As animals move through their habitats they use energy to fulfill metabolic costs related to their age, activity level, reproductive status, and local environmental conditions. Human disturbance may offset natural energetics by scaring animals away from food rich regions and demanding extra energy to fuel behavioral responses to disturbance. By impacting the foraging success of individuals, human disturbance can ultimately affect population reproductive and mortality rates. The model developed by Cara Alyse Gallagher was applied to investigate the effects of disturbance from underwater noise and climate change on porpoise populations. This model is general and can be applied to other marine mammal species to understand and mitigate the impacts of human disturbance on their populations. 

The PhD study was completed at Department of Bioscience, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
