1. Trade-off between starvation and predation : Weight-watching in Yellowhammers
Sammanfattning : In this thesis I show that captive yellowhammers (Emberiza citrinella) strategically adjusted their level of body mass and diurnal trajectory of mass increase to experimentally increased predation risk. During winter, small birds need large fat reserves to survive the night. Therefore, they build up fat reserves every day. LÄS MER
2. Commuting time choice and the value of travel time
Sammanfattning : In the modern industrialized society, a long commuting time is becoming more and more common. However, commuting results in a number of different costs, for example, external costs such as congestion and pollution as well as internal costs such as individual time consumption. LÄS MER
3. Growth versus the Environment - Is There a Trade-off?
Sammanfattning : This book shows that the intensity of use of energy and materials in OECD countries is diminishing over time despite falling metal and energy prices. Material demand is sometimes falling in absolute terms, but there are also a few examples of rapid growth. LÄS MER
4. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency
Sammanfattning : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. LÄS MER
5. Evolution of Plants : a mathematical perspective
Sammanfattning : The Earth harbors around 300 000 plant species. The rich and complex environment provided by plants is considered a key factor for the extraordinary diversity of the terrestrial fauna by, for example, providing food and shelter. LÄS MER
