1. Visually guided swimming in box jellyfish: A study of swimming behaviour in response to visual stimuli
Abstract : Most animals use eyes to guide their behaviour. Analysing, and understanding, visually guided behaviours gets more complicated the more advanced the animal gets. Box jellyfish provide a relatively simple system for understanding visually guided behaviours. READ MORE

2. 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

3. Behaviour and metabolic rates of brown trout and Atlantic salmon : Influence of food, environment and social interactions
Abstract : For Atlantic salmon (Salmo salar) and brown trout (Salmo trutta), the decision to migrate or when to migrate is believed to be influenced by the individual’s metabolic rate (MR) relative its food intake. As MR was expected to be related to behaviour, the potential links between behaviour and metabolic costs was studied. READ MORE

4. Fine stream wood : effects on drift and brown trout (Salmo trutta) growth and behaviour
Abstract : Stream ecosystems and their riparian zones have previously been regarded as two different ecosystems, linked through numerous reciprocal subsidies. Today, ecologists agree that the stream and the riparian zone should be regarded as one system, the stream-riparian ecosystem, which is characterised largely by the subsidies between land and water.

5. Relations between metabolic rate, migration and behaviour in Atlantic salmon (Salmo salar) and brown trout (Salmo trutta)
Abstract : ABSTRACT Migration is common among populations of brown trout (Salmo trutta) and Atlantic salmon (Salmo salar). However, not all individuals in the same population migrate, a phenomenon referred to as partial migration. READ MORE
