1. Determinants of genomic diversity in the collared flycatcher (Ficedula albicollis)
Sammanfattning : Individuals vary from each other in their genetic content. Genetic diversity is at the core of the evolutionary theory. Rooted in a solid theoretical framework developed as early as the 1930s, current empirical observations of genomic diversity became possible due to technological advances. LÄS MER
2. MHC and genomic diversity in Atlantic salmon (Salmo salar L.)
Sammanfattning : In this thesis I present studies concerning genomic diversity and genetic heterogeneity as well as the evolution and maintenance of genetic variation at a specific immune defence gene in Atlantic salmon (Salmo salar, L.). LÄS MER
3. Diversity of Skin Infections
Sammanfattning : The identification of infectious agents in cancer has been one of the most rewarding endeavors in cancer research. Currently about 20% of the global cancer burden is linked to an infection. A common characteristic of virus-induced cancer is an increased incidence in immunosuppressed patients, presumably because of impaired host control of virus. LÄS MER
4. The roles of demography and natural selection in shaping genome-wide variation of Norway spruce
Sammanfattning : Understanding the relative contribution of genetic drift, natural selection, and mutation to genetic variation, and quantifying adaptive evolution and the effects of natural selection in species are enduring goals of evolutionary genetics. Norway spruce (Picea abies) is one of the most important conifer species that dominates from both an ecological and economical point of view in many boreal ecosystems. LÄS MER
5. Diversity and persistence of Helicobacter pylori
Sammanfattning : Helicobacter pylori is an exceptionally diverse bacterial species, and every infected individual harbors a unique strain, apart from the strain concordance found in some families. The infection is usually acquired during childhood and once established, persists for life unless treated with antibiotics. LÄS MER
