Sammanfattning : The risk of predation is an important factor for our understanding of animal behaviour in general. This thesis investigates the influence of predation risk on fighting behaviour in the cichlid fish Nannacara anomala. LÄS MER
Sammanfattning : A central goal of evolutionary biology is to understand the processes responsible for morphological, genetic and behavioural differentiation between sexes and among geographically distinct populations. Perhaps the most significant processes are genetic drift, natural selection, phenotypic plasticity and sexual selection. LÄS MER
Sammanfattning : Animals show a great variety in physiological and behavioural responses to stressors. These responses are often bimodally distributed within populations and show consistency on an individual level over time and across situations, which in terrestrial vertebrates have been identified as proactive and reactive stress coping strategies.

4. Behaviour and metabolic rates of brown trout and Atlantic salmon : Influence of food, environment and social interactions
Sammanfattning : 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. LÄS MER
