31. Genetic Disequilibria and the Interpretation of Population Genetic Structure in Daphnia
Sammanfattning : Understanding the processes that shape the spatial distribution of genetic variation within species is central to the evolutionary study of diversification and demography. Neutral genetic variation reflects past demographic events as well as current demographic characteristics of populations, and the correct interpretation of genetic data requires that the relative impact of these forces can be identified.

32. Insights into the ecology and genetics of lichens with a cyanobacterial photobiont
Sammanfattning : Nature conservation requires an in-depth understanding of the ecological processes that influence species persistence in the different phases of a species life. In lichens, these phases comprise dispersal, establishment, and growth. LÄS MER
33. Migratory behaviour and adaptive divergence in life-history traits of pike (Esox lucius)
Sammanfattning : Population divergence shaped by natural selection is central to evolutionary ecology research and has been in focus since Darwin formulated “The origin of species”. Still, the process of adaptive divergence among sympatric populations is poorly understood. LÄS MER
34. Quantification of population exposure and health impacts associated with air pollution
Sammanfattning : There is substantial evidence that air pollution, in particular particulate matter (PM), affects our health. The overall objective of this thesis is to understand and quantify population exposure to ambient air pollution and related health impacts. LÄS MER
35. Att tillaga en region : Den regionala maten i representationer och praktik - exemplet Skärgårdssmak
Sammanfattning : The connection between specific foods and specific places has, over the course of the past decade or so, come to constitute an important instrument in regional development strategies. The objective of this thesis is to study how regions are created and communicated in discourses on regional food and to examine how representations of regions are interpreted, given meaning and materialised in social practice.
