1. Migratory behaviour of Baltic salmon (Salmo salar L.) : adaptive significance of annual cycles
Abstract : This thesis evaluates the adaptive significance of annual cycles on the migratory behaviour of Baltic salmon (Salmo salar L.). The studies have included field experiments as well as laboratory studies gf maturity and migratory behaviour patterns of smolts and postsmolts mainly from the Angerman river population. READ MORE

2. Adaptive behaviour in traffic : An individual road user perspective
Abstract : Road-user adaptation is a prerequisite for traffic to run smoothly. By adaptation, the road user aims to ensure a feeling of comfort according to his or her present state and capability. In this thesis, adaptive behaviour of car drivers and cyclists in response to different factors is explored, using the individual perspective of the road user. READ MORE

4. Domestication effects on foraging behaviour : consequences for adaptability in chickens
Abstract : The main aim of this thesis was to study domestication effects on foraging behaviour in chickens and to investigate whether and how domestication and selection for high production have influenced adaptability in chickens. Two domestic strains of chickens (egg layers and meat type chickens) and their wild ancestor, the red jungle fowl (RJF) were compared in different test situations with respect to foraging behaviour and adaptability.

5. Predation as a driver of reproductive isolation - from adaptive divergence to hybrid inviability
Abstract : Natural selection can play an important role in the origin of new species. When reproductive isolation evolves as a result of ecologically-based divergent natural selection, the process is referred to as ecological speciation. In most organisms, sufficient reproductive isolation is considered to be essential for the establishment of new species. READ MORE
