1. Exploring the species boundaries in terrestrial clitellates (Annelida: Clitellata)
Abstract : The biological diversity in the soil is much higher than most people can imagine, and a very important group of animals living there are earthworms and other clitellate worms. It has been found that several clitellate morphospecies are in fact complexes of so called cryptic species, and the number of species in this group may be much higher than previously believed.

2. Chicken domestication : Effects of tameness on brain gene expression and DNA methylation
Abstract : Domestication greatly increases phenotypic variation in a short time span, with selection for a single phenotype and a plethora of associated phenotypic changes as an outcome of the process. The domestication process influences the underlying genomic architecture of a species, and the success and speed of the process is likely influenced by it. READ MORE

3. Multiplex markers in a plant breeding perspective
Abstract : Plant breeding is largely depending on the repeated selection for desirable traits. This process is both time and labour consuming, making the development of commercial plant varieties a slow and costly activity. READ MORE

4. Application of Molecular Markers in Sugar Beet Breeding
Abstract : Around 1750 a German chemist discovered it to be possible to extract sugar crystals from beet juice. Since then, breeding and improved agricultural practices have increased the concentration of sucrose per root from around 4% to around 18%. READ MORE

5. Developmental Neurotoxicity of Environmental Pollutants : Effects on neuronal protein markers after neonatal exposure
Abstract : This thesis focused on investigations of the developmental neurotoxic effects of bisphenol A (BPA) or perfluorohexane sulfonate (PFHxS), after a single neonatal exposure, during a critical period of the brain development in mice.BPA is a well-known industrial chemical used in the production of polymer products and PFHxS is used as an industrial additive as a surfactant.
