Seasonal Ecology
Seasonal Ecology
Seasonality is a central template in nature and an important selective force. We aim to understand how seasonal environments shape ecological processes and evolutionary adaptations and how human stressors impact these processes. Most of our research questions have an annual cycle perspective to them. We run both theoretical and empirical studies and strive for concept rich research anchored in mechanisms and theory. Coastal and marine organisms form the main part of our work, but with some studies also in terrestrial systems including links between sea and land.
The Seasonal Ecology Group is a research lab led by Øystein Varpe and based at Department of Biological Sciences, University of Bergen. It is embedded in the larger multi-lab unit Theoretical Ecology Group

Our field is evolutionary ecology, with particular attention to how seasonality shapes ecological processes and evolutionary adaptations.
Central topics in our lab:
Life history theory
Phenology
Population biology
Predator-prey interactions
Foraging ecology
Ecosystem connections & meta-ecosystems
Sea - land interactions
Marine and coastal ecology
Ecological modelling
