1. Quantitative genetic variation in declining plant populations
Abstract : The ecological and genetic effects of habitat fragmentation are an issue of major concern in current conservation biology. Habitat fragmentation results in smaller habitat areas and as a consequence smaller and more isolated populations. Many habitats have become fragmented through human activities such as forestry and agricultural development. READ MORE

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. Genetic structure of natural populations : aspects of the association between genetical and morphological variability patterns
Abstract : Most species comprise a number of more or less reproductively isolated subpopulations. These subpopulations may exhibit striking differences in morphology and ecology, and on the basis of those differences they are often given the rank of subspecies, race, stock, variety, etc. READ MORE

4. Mapping genetic diseases in northern Sweden
Abstract : The population of northern Sweden has previously been shown to be well suited for the mapping of monogenic diseases. In this thesis we have tested the hypothesis that this population could also be used for efficient identification of risk genes for common diseases. READ MORE

5. Neurospora tetrasperma from Natural Populations : Toward the Population Genomics of a Model Fungus
Abstract : The study of DNA sequence variation is a powerful approach to study genome evolution, and to reconstruct evolutionary histories of species. In this thesis, I have studied genetic variation in the fungus Neurospora tetrasperma and other closely related Neurospora species. I have focused on N. READ MORE
