Cat Horswill

My research focuses on investigating the mechanisms that shape the population dynamics of marine top predators. I study the links between environmental variation and population dynamics, and how populations respond to extreme fluctuations in prey abundance. I investigate why life-history strategies vary between populations of the same species, and how we can use life-history theory to reconstruct population-specific strategies when empirical data are unavailable. I am also interested in demographic compensation and the evolution of life-history characteristics. To address these topics, I use fieldwork, biochemical analysis and advanced statistical modelling. I have worked extensively on the population dynamics of temperate and polar species of seabird, as well as the life history profiles of tunas and sharks.
