16. Inferring Evolutionary Processes of Humans
Sammanfattning : More and more human genomic data has become available in recent years by the improvement of DNA sequencing technologies. These data provide abundant genetic variation information which is an important resource to help us to understand the evolutionary history of humans. LÄS MER
17. Demography and Polyploidy in Capsella
Sammanfattning : Studies of demography and population structure give insight into important evolutionary processes such as speciation and diversification. In the present work I perform such studies in the genus Capsella, which has three species: C. grandiflora, an outcrossing diploid, C. rubella a selfing diploid, and C. LÄS MER
18. Socially stable alcoholics: What characterises them? Drinking patterns, personality and health aspects of psychosocial and clinical importance
Sammanfattning : People who misuse alcohol are a heterogeneous group with different etiology, social and clinical characteristics. This thesis includes four studies whose aim was to characterise so called socially stable alcoholics (i.e. individuals with preserved psychosocial functioning) regarding personality, physical and mental health and drinking patterns.

19. Investigating the impacts of Late Pleistocene climate change on Arctic mammals using palaeogenomics
Sammanfattning : The climatic fluctuations of the Late Pleistocene likely had a large impact on the evolutionary history of Arctic species. Palaeogenomics is a useful tool to shed light on how past populations responded to these climatic shifts and the associated ice sheet dynamics and sea level change. LÄS MER
20. Population ecology and management of waders breeding on coastal meadows
Sammanfattning : Many wader (Charadrii) populations are declining throughout in Europe, but the underlying causes are often poorly known and diverse. To fully grasp the reasons behind declines in vulnerable wader populations, it is crucial to understand the demography. LÄS MER
