Behavioural Ecology; Seasonal and life history timing
My research focus is in the area of behavioural ecology – the study of evolutionary explanations for individual variation in behaviour and life history – and phenology – the study of seasonal timing. I’m particularly fascinated with how individuals time their reproduction in seasonal environments and over their lifespan. Reproductive timing is a resource allocation problem, and I use this principle to explain why timing varies among individuals and how it evolves in changing environments. These are critical questions in this era of climate change, when phenological mismatch with the environment has the potential to negatively affect populations.
