Lesley Morrell is interested in how animals respond to their environments, particularly in the context of anti-predator aggregation and environmental change. Her group studies how animals interact with one another in their foraging, mating and social decisions, and how the environment affects these behaviours. Projects include the behavioural responses of small fish to increasing environmental turbidity, the effect of resource density on attack rates by foraging insects, and understanding how predators target prey, using principles taken from human psychology. Lesley is also interested in how students learn, and evaluating the effectiveness of learning and teaching strategies.

Dr Morrell welcomes applications in all areas of her research, particularly those relating to the evolution of aggregation as an anti-predator defence. She is able to supervise both empirical and theoretical projects and is willing to support applications from students wishing to access their own funding.
