1. Fungal disease dynamics, genetic variation and biodiversity-yield relationships : — a study along a gradient of coffee management in southwestern Ethiopia
Sammanfattning : Intensification of agricultural systems is a major threat to the associated biodiversity and could also affect the dynamics of pests and pathogens. One such system that is currently under an intensification trajectory is the production of Arabica coffee. LÄS MER
2. Behavioural differences and genetic relationships between four captive populations of red junglefowl (Gallus gallus) : possible implications for conservation
Sammanfattning : Conservation of species is to a large extent carried out by zoos where animals are kept in small populations under protected conditions. The ultimate goal of such ex situ conservation programs is to eventually reintroduce the animals into natural habitats to provide support for the survival of the species. LÄS MER
3. Genetic studies in rheumatoid arthritis : familial studies and analysis of relationships to atherothrombotic comorbidity
Sammanfattning : Background. Rheumatoid arthritis (RA) is an autoimmune disease mainly affecting the joints but has also extra articular manifestations and an increased cardiovascular (CV) co-morbidity. Rheumatoid factor (RF) and antibodies against citrullinated proteins/peptides (ACPA) are diagnostically important and are related to a more severe disease. LÄS MER
4. Alcohol Consumption among Adolescents : Psychosocial and Genetic influences
Sammanfattning : The present thesis is based on four studies focusing on alcohol consumption among Swedish adolescents, and therewith related psychosocial and genetic factors. One main objective was to study the reasons for drinking alcohol among different population - representative samples of adolescents in order to identify motives for drinking. LÄS MER
5. Sex Chromosome Evolution in a Hermaphrodite : Genetic and phenotypic relationships between sex roles
Sammanfattning : Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. LÄS MER
