1. Biased Evolution : Causes and Consequences
Sammanfattning : 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. LÄS MER
2. The evolution of sex chromosomes and sex-linked sequences in birds
Sammanfattning : Identifying the processes involved in the evolution of suppressed recombination between sex chromosomes and understanding their consequences for the evolutionary dynamics of sex-linked loci have been major topics of research during the last century. In this thesis, I used the avian ZW system, where females are the heterogametic sex, to investigate the underlying processes in sex chromosome evolution in birds. LÄS MER
3. Catching the Spore killers : Genomic conflict and genome evolution in Neurospora
Sammanfattning : A genome is shaped by many different forces. Recombination can for instance both create and maintain genetic diversity, but the need to locally reduce recombination rates will also leave specific signatures. LÄS MER
4. Magnetooptical properties of dilute nitride nanowires
Sammanfattning : Nanostructured III-V semiconductors have emerged as one of the most promising materials systems for future optoelectronic applications. While planar III-V compounds are already at the center of the ongoing lighting revolution, where older light sources are replaced by modern white light LEDs, fabricating such materials in novel architectures, such as nanowires and quantum dots, creates new possibilities for optoelectronic applications.

5. Synthesis and Characterization of ZnO Nanostructures
Sammanfattning : One-dimensional ZnO nanostructures have great potential applications in the fields of optoelectronic and sensor devices. Therefore, it is very important to realize the controllable growth of one-dimensional ZnO nanostructures and investigate their properties. LÄS MER
