Animals make behavioural and reproductive decisions that maximise their lifetime reproductive success, and thus their fitness, in light of periodic and stochastic variability of the environment. Modelling the variation of an individuals energy levels formalises this tradeoff and helps to quantify the population-level consequences of stressors e.g. disturbance from human activities and environmental change that can affect behaviour or physiology. In this study, we develop a dynamic state variable model for the spatially explicit behaviour, physiology and reproduction of a female, long-lived, migratory marine vertebrate.
