2. Piscivore-prey fish interactions - consequences of changing optical environment
Sammanfattning : Predator-prey interactions are a primary structuring force in aquatic systems. A change in the predator-prey interactions may cause a change in the strength of trophic cascades and even resulting in ecosystem shifts. LÄS MER
3. Financial Applications of Markov Chain Monte Carlo Methods
Sammanfattning : This thesis consists of four empirical studies on financial economics. The first chapter contains a short summary of the thesis. LÄS MER
4. Analysis of Adaptation in Human Postural Control
Sammanfattning : The ability to obtain correct balance control information and adjust motor performance appropriately are essential elements in effective postural control. However, functional disorders may affect the reliability of receptor information and ability to carry out corrective motions needed to maintain balance. LÄS MER
5. Effects of commercial hatchery processing on behaviour and welfare of laying hens
Sammanfattning : Around the world, more than 76.7 million tons of eggs are consumed every year. To meet this demand, billions of laying hen chicks are produced under highly industrial circum-stances. These chicks are hatched in commercial hatcheries for laying hens in a presumably stressful environment, which might affect their welfare and production later in life. LÄS MER
