1. Genetic algorithm based design of power system stabilizers
Sammanfattning : .... LÄS MER
2. Speciation and Metabolic rate : Insights from an avian hybrid zone
Sammanfattning : The role of divergent climate adaptation in speciation has received surprisingly little scientific attention. My dissertation research focused on how resting metabolic rate (RMR) relates to the build up of prezygotic and postzygotic isolation in a natural Ficedula flycatcher hybrid zone. LÄS MER
3. Dynamics and Performance of a Linear Genetic Programming System
Sammanfattning : Genetic Programming (“GP”) is a machine learning algorithm. Typically, Genetic Programming is a supervised learning algorithm, which trains on labeled training examplesprovided by the user. The solution output by GP maps known attributes to the known labels. LÄS MER
4. 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.

5. Breeding System Evolution and Pollination Success in the Wind-Pollinated Herb Plantago maritima
Sammanfattning : In this thesis, I examined variation in sex expression and mating patterns in the sexually polymorphic, wind-pollinated herb Plantago maritima. With a combination of field studies, greenhouse experiments, and genetic analyses, I (a) examined factors influencing sex ratio variation in gynodioecious plants (in which hermaphrodites and females coexist), (b) discovered variation in breeding system, (c) investigated density-dependence of seed production, and (d) documented genetic variation within and among populations close to the northern range margin in Europe.
