1. Biased Evolution : Causes and Consequences
Abstract : In evolution alternative genetic trajectories can potentially lead to similar phenotypic outcomes. However, certain trajectories are preferred over others. These preferences bias the genomes of living organisms and the underlying processes can be observed in ongoing evolution. READ MORE

2. Avian Genome Evolution - Gene Expression, Gene Divergence and Sexual Dimorphism
Abstract : This study has focused on: (i) differences in how males and females use the genes in the genome, (ii) how sex chromosomes evolve and (iii) how the evolutionary rate of genes are affected by the chromosome on which they are located on and the gene expression level they experience. A large-scale microarray was developed for the zebra finch, Taeniopygia guttata and techniques were developed so that this microarray could also be used for wild passerine birds. READ MORE

3. Intrinsic disorder and tandem repeats - match made in evolution : Computational studies of molecular evolution
Abstract : Proteins are both the building blocks and workers of the cell, carrying out most of the important functions. For a long time, their structure has been regarded as the primary factor for their function, but intrinsically disordered proteins demonstrate an alternative to this paradigm. READ MORE

4. On the Evolution of the Avian Transcriptome
Abstract : Change in gene expression is a powerful tool for evolution, because seemingly small expression changes can contribute important steps towards adaptation without necessarily affecting the whole organism. There is still much to learn about how gene expression evolves on genome- and population-wide levels, especially in non-model organisms. READ MORE

5. Exploring Brain Gene Expression i Animal Models of Behaviour
Abstract : The genetic basis for behavioural traits is largely unknown. The overall aim of this thesis was to find genes with importance for behavioural traits related to fear and anxiety. Microarray analysis was used to screen expression profiles of brain regions important for emotional behaviour in dogs, wolves, foxes and mice. READ MORE
