I study the ecology and evolution of freshwater fishes and climate effects of forestry
In one project, I study the rapid speciation that occurs in many Scandinavian whitefish populations. The overarching objective is to understand how a speciation process initiates - what's the "spark" that makes individuals to develop in different directions? In a subproject we study the history of different whitefish populations by analyzing DNA preserved in lake sediments.
The climatic effects of forestryare studied in collboration with reserachers at the Mid Sweden University. These projects focus, among other things, on the effects of thinning and altered rotation length on emissions of CO2.
A third project investigates how climate, connectivity, and non-native species affect the distribution of freshwater fishes. In a subproject we are developing a map-based web service, where fishery managers can make experiments, for example by turning up the temperature, removing dams or introducing non-native species and then examine the consequences for different species.
