1. Hybrid zones and speciation – insights from the European crow hybrid zone
Sammanfattning : In hybrid zones genetically differentiated populations meet and interbreed. As they result from ongoing divergence and potential speciation, such zones provide opportunities to study how different factors affect this process. The hybrid zone between the all black carrion crow (Corvus corone corone) and the grey and black hooded crow (Corvus c. LÄS MER
2. 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
3. The Genetics of Speciation and Colouration in Carrion and Hooded Crows
Sammanfattning : A fundamental goal in biological research is to gain an understanding of the evolutionary processes and genetic elements that drive speciation. Genes responsible for reproductive isolation in young divergent lineages are particularly poorly known. In this thesis, the speciation genetics of carrion (Corvus (corone) corone) and hooded (C.

4. Genus Brachyspira in birds : phenotypes, phylogeny and pathogenicity
Sammanfattning : Spirochaetes of genus Brachyspira colonize the large intestine of some mammals and birds, and cause intestinal disease and production losses in pigs and chickens. The precise significance of Brachyspira spp. colonization in birds, the bacterial species involved, and the epidemiology are incompletely understood. LÄS MER
