1. Local Adaptation, Countergradient Variation and Ecological Genetics of Life-history Traits in Rana Temporaria
Sammanfattning : The main aim of this work was to identify local adaptation processes in amphibian populations, thereby improving the general understanding of genetics and mechanisms behind the evolution and maintenance of biological diversity. Phenotypic and genetic variation in life-history traits was studied within and between populations common frog (Rana temporaria) populations along a 1600 km transect from southern Sweden to northern Finland.

2. Phenotypic plasticity and local adaptation in island populations of Rana temporaria
Sammanfattning : Phenotypic plasticity is the ability of a genotype to express different phenotypes in different environments. Despite its common occurrence, few have investigated differences in plasticity between populations, the selection pressures responsible for it, and costs and constraints associated with it. LÄS MER
3. Tracing selection and adaptation along an environmental gradient in Populus tremula
Sammanfattning : The distribution of the expressed genotype is moved around in the population over time byevolution. Natural selection is one of the forces that act on the phenotype to change the patterns ofnucleotide variation underlying those distributions. LÄS MER
4. Direct and Large-Eddy Simulations of Turbulent Boundary Layers with Heat Transfer

5. Numerical studies of receptivity, stability and transition of wing and turbine blade boundary layers
Sammanfattning : In the present thesis, receptivity, stability and laminar-turbulent transition of different boundary-layer flows are addressed and investigated by means of direct numerical simulations. In particular, flows over a wing and a low-pressure-turbine (LPT) blade have been the main focus. LÄS MER
