1. Spatial Modelling of Coastal Fish – Methods and Applications
Abstract : Environmental factors influence species and habitats on multiple scales creating a mosaic of distribution patterns. Studying factors shaping these patterns are central to our understanding of population dynamics and ultimately ecosystem functioning. READ MORE

2. Genetic Adaptation and Speciation in Darwin’s Finches and Atlantic Herring
Abstract : Natural selection acts on existing genetic variation to drive genetic adaptation of organisms to various ecological niches. Interaction between closely related populations, through processes such as competition and hybridization, may either lead to their divergence or population fusion, which has consequences for adaptation and the formation of species.

3. Aposematism, Crypsis and Population Differentiation in the Strawberry Poison Frog
Abstract : Evolutionary transitions between the two major predator avoidance strategies aposematism and crypsis are expected to be associated with changes in many important traits of animals. However, empirical studies on populations experiencing ongoing or recent transitions between these strategies are rare. READ MORE

4. Climate change time machine : Adaptation to 30 years of warming in the Baltic Sea
Abstract : Earth mean surface temperature has increased by 1 °C since the industrial revolution, and this has already had considerable effects on animal and plant species. Ecological responses to the warming climate – often facilitated via phenotypic plasticity – are ubiquitous. READ MORE

5. Speciation and Metabolic rate : Insights from an avian hybrid zone
Abstract : The role of divergent climate adaptation in speciation has received surprisingly little scientific attention. My dissertation research focused on how resting metabolic rate (RMR) relates to the build up of prezygotic and postzygotic isolation in a natural Ficedula flycatcher hybrid zone. READ MORE
