1. Cycles of voles, predators, and alternative prey in boreal Sweden
Sammanfattning : Bank voles, grey-sided voles, and field voles had synchronous 3-4 year density cycles with variable amplitudes which averaged about 200-fold in each species. Cycles of vole predators (red fox and Tengmalm's owl), and their (foxes') alternative prey (mountain hare and forest grouse) lagged behind the vole cycles. LÄS MER

Sammanfattning : Surgical tissue trauma is a strong stimulus for local inflammation, including leukocyte recruitment. While such a response may be of importance for the defense against microorganisms, it is also clear that inflammation may contribute to further tissue injury. LÄS MER
4. Pharmacological and Developmental Aspects on Neuronal Plasticity
Sammanfattning : Neuronal plasticity means the ability of the brain, its cells and networks to adapt and adjust to new challenges, a process which is ongoing throughout life. The goal of this thesis was to gain better understanding of the molecular events that follow different types of stimulations of brain structures such as the hippocampus, a key region for cognitive functions with overriding control on the corticosteroid system.
