1. Mating behaviour and sexual selection in non-lekking fallow deer (Dama dama)
Sammanfattning : This thesis examines both behavioural and morphological traits influencing male mating success in non-lekking fallow deer (Dama dama). The thesis contains results based on behavioural observations and experimental studies made on Öland and around Uppsala, Sweden. LÄS MER
2. Behaviour of Pine Sawflies in Relation to Pheromone-Based Pest Management
Sammanfattning : Pine sawflies (Hymenoptera: Diprionidae) are severe pine defoliators. This thesis investigated sawfly behaviour related to the use of pheromones in integrated pest management, including monitoring with pheromone traps and mating disruption. LÄS MER
3. Mating behaviour in Drosophila melanogaster and its implication to genetic variation
Sammanfattning : Not much is known about the mechanisms affecting the genetic composition of populations of different species. To investigate one of these potential mechanisms, mating behaviour, the fruit fly Drosophila melanogaster, was chosen as an experimental animal. LÄS MER
4. Male moth behaviour and perception in pheromone plumes
Sammanfattning : Behaviour of male moths and electrophysiological responses of male pheromone-specific olfactory receptor neurones were studied in two model species, the oriental fruit moth Grapholita molesta and the turnip moth Agrotis segetum. The studies were aimed at elucidating the relative importance of different mating disruption mechanisms. LÄS MER
5. Genetic Structuring and the Evolution of Lekking Behaviour in the White-bearded Manakin, Manacus manacus
Sammanfattning : Genetic structuring is common in natural populations. It is important to identify and consider population structure when studying evolutionary processes. Recently, the discovery of genetic structuring in some lekking bird species has opened up new perspectives on our understanding of the evolution of lek mating systems. LÄS MER
