Cat Horswill

My research focuses on investigating the mechanisms that regulate and determine the population dynamics of marine top predators. I study the links between environmental variation, demography and population dynamics, and how populations respond to extreme fluctuations in prey abundance. I investigate methods for estimating demographic parameters from fragmented and error-prone datasets, and often use Bayesian models for this purpose. I am also interested in demographic compensation and the evolution of life-history characteristics. I have worked extensively on the population dynamics of temperate and polar species of seabird, and more recently on the life history profiles of tunas and sharks.

I am currently a NSF and NERC funded post-doc (2016-2019) with the University of Glasgow, Rutgers University, University of California and Simon Fraser University. This project is in collaboration with Jason Matthiopoulos, Holly Kindsvater, Marc Mangel, Nick Dulvy and Maria Jose Juan Jorda. The aim of the project is to develop a cross taxa method that combines incomplete and multi-species datasets in order to reconstruct full life-history profiles for data-limited populations.
