2. 1. Determinants of genomic diversity in the collared flycatcher (Ficedula albicollis)

   Author : Ludovic Dutoit; Hans Ellegren; Asher Cutter; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; collared flycatcher; Ficedula albicollis; enetic diversity; sexual conflict; effective population size; nucleotide diversity; linked selection; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Abstract : 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. READ MORE

4. 2. MHC and genomic diversity in Atlantic salmon (Salmo salar L.)

   Author : Jakob Lohm; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; cytogenetik; Genetik; cytogenetics; Genetics; nucleotide diversity; isolation-by-distance; DGGE; AFLP; furunculosis; disease resistance; Arctic charr; brown trout; Atlantic salmon; population genetics; genetic variation; Mhc class IIB; Animal ecology;

   Abstract : 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.). READ MORE

5. 3. Diversity of Skin Infections

   Author : Johanna Ekström; Malmö Klinisk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human papillomavirus; high-throughput sequencing; Staphylococcus auereus; multiple displacement amplification; non melanoma skin cancer;

   Abstract : 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. READ MORE

6. 4. The roles of demography and natural selection in shaping genome-wide variation of Norway spruce

   Author : Xi Wang; Pär K. Ingvarsson; Carolina Bernhardsson; Xiao-Ru Wang; Nathaniel Street; Tanja Pyhäjärvi; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; whole-genome resequencing; variant calling; genetic linkage map; nucleotide diversity; natural selection;

   Abstract : 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. READ MORE

7. 5. Diversity and persistence of Helicobacter pylori

   Author : Annelie Lundin; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Helicobacter pylori; genomic diversity; cag pathogenicity island; Nudix hydrolase;

   Abstract : 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. READ MORE
