1. From wolf to dog: Behavioural evolution during domestication
Sammanfattning : Biologists since Darwin have recognized that domestication, where species are selected to live in human-controlled environments, exerts strong selection on organisms and dramatically impacts their evolutionary trajectories. Across domesticated mammal species, characteristic morphological, physiological and behavioural changes occur simultaneously, as correlated traits, a phenomenon known as the domestication syndrome.

2. Evolution of MHC Genes and MHC Gene Expression
Sammanfattning : Polymorphism in coding regions and regions controlling gene expression is the major determinant of adaptive differences in natural populations. Genes of the major histocompatibility complex (MHC) possess a high level of genetic variation, which is maintained by selection over long coalescence times. LÄS MER
3. Consequences of the Domestication of Man’s Best Friend, The Dog
Sammanfattning : The dog was the first animal to be domesticated and the process started at least 15 000 years ago. Today it is the most morphologically diverse mammal, with a huge variation in size and shape. LÄS MER
4. Conservation Genetics of Wolves and their Relationship with Dogs
Sammanfattning : Management of wolves is a complex issue, and molecular genetics is an important tool in this work. Molecular genetics can provide important information at the species, population and individual level, which can be essential for the development of management programs aiming at the long term survival of wolf populations.

5. Exploring Brain Gene Expression i Animal Models of Behaviour
Sammanfattning : The genetic basis for behavioural traits is largely unknown. The overall aim of this thesis was to find genes with importance for behavioural traits related to fear and anxiety. Microarray analysis was used to screen expression profiles of brain regions important for emotional behaviour in dogs, wolves, foxes and mice. LÄS MER
