1. Genetic variation in natural populations: a modeller's perspective
Abstract : Thanks to advances in genome sequencing, empirical patterns of within- and between-species genetic variation are readily available. By studying these patterns much has been learned about the evolutionary histories of species. But the causes and consequences of different evolutionary histories are still difficult to tell apart.

2. Genetic variation in structured populations
Abstract : It is widely acknowledged that the process of speciation in the presence of gene flow between different ecotypes is common in nature. However, the mechanisms underlying speciation are not understood. READ MORE

3. Conservation Genetics of Scandinavian Wolverines
Abstract : In this thesis, genetic methods for individual identification and sex determination of wolverines from non-invasive samples were developed and applied in genetic monitoring of Scandinavian wolverine populations. Paternity and mating system of wolverines were studied by combining genetic analysis with telemetry data. READ MORE

4. Female choice and paternal care in the fifteen-spined stickleback, Spinachia spinachia
Abstract : In the fifteen-spined stickleback, Spinachia spinachia, males provide females with direct benefits by fanning, cleaning and guarding the offspring. Males announce their parental skills through intense body shakes during courtship. Females preferred to mate with more intensely shaking males. READ MORE

5. Evolutionary Resolutions of Conflicts with Mates and Offspring
Abstract : In sexual conflicts and conflicts between parents and offspring, natural selection acts in different directions on the two sides. For example, males may be selected to achieve many mates, but female fitness may be maximised by monogamy. In this thesis I study the evolutionary outcome of these situations mainly by theoretical modelling. READ MORE
