- Evolutionary and Seasonal Ecology
- Main aim: understand why we observe variation in life histories and behavior and how this variation influences interactions, populations and ecosystems.
I work in highly seasonal environments and study the scheduling of annual events and the trade-offs involved. Key traits: reproduction, energy storage, dormancy and migrations. What is the scope of state-dependent responses? What is the role of phenotypic plasticity versus evolution? Most of my work is on the ecology and evolution of birds, fish and zooplankton using mathematical models and statistical analyses of data. An important component of my work is to use the insights we gain to understand and predict how organisms respond to environmental variability and change, with pollution, harvesting and climate change as central stressors.
Student project opportunities:
