Research title: The effects of climate-related stressors on fish social behaviour
Research summary
My PhD research focuses on the interactions between individual and group social behaviour in fishes subjected to anthropogenic stressors. I am investigating the links between changes in social behaviours among individuals and changes in group dynamics, and how this varies across environmental conditions.
