Research

My main research focuses on which factors determine the dynamics of bird population size and distribution, which is directly related to my position as head of the Swedish Bird Survey, a nationwide program for monitoring the breeding birds in Sweden.
About two thirds of the species monitored are migratory birds. The extent to which birds are capable of carrying out a succesful migration, a subject at the core of the AMR-project, will to some extent manifest itself in their populaton trends. Therefore, analysing species trends in numbers and distribution, in relation to their migratory status, will be one way of understanding the fitness consequences of various migratory strategies.
I’m also very much interested in migration as such, in particular the behaviour, physiology and energetics of fuel deposition and flight. Present focus is on migratory Great Snipes and their migration strategy, which we study by geolocators. Since long I also study the population ecology, moult and fuel deposition of passerines in Swedish Lapland.
