6. Defining Dukeship : The Problem of Royal Spares and Dynasty Formation in Sweden, 1556-1622
Abstract : This book examines how dukeship – the position of being a duke – was defined and negotiated in Sweden between the late 1550s and the early 1620s. The aim is to shed light on how the structural problem of royal spares, with dukes as pillars and perils of hereditary monarchy, influenced politics and the integration process of a ruling house.

7. Asymptotics, weak convergence and duality in population genetics
Abstract : This thesis consists of four papers on asymptotic results and stochastic duality for some processes in mathematical population genetics. The focus is on Wright-Fisher diffusions and coalescent processes, which model, respectively, the evolution of frequencies of genetic types and genealogies in a population,and play a key role in inference on genetic data sets.

8. Biodiversity and genetic patterns in marine invertebrates
Abstract : Abstract: Systematics based on genetic data has both confirmed and contradicted earlier, morphologically defined species and their relatedness. Morphology does not always correspond to genetic lineages, and this will inevitably affect both traditional systematics as well as biodiversity assessments. READ MORE

9. Species Delimitation and Phylogenetic Relationships. A study of Silene sections Atocion and Cryptoneurae
Abstract : Abstract The existence of conflicting genealogies of different genes through the evolution of species complicates the inference of phylogenetic relationships. The Multispecies Coalescent (MSC) model provides a theoretical background that account for the stochasticity in the genealogical process, thus providing systematists with a potentially objective way of testing alternative hypotheses of putative species.

10. The use of molecular markers for identifying species diversity and functional variation of ectomycorrhizal fungi
Abstract : Ectomycorrhiza (EM) is a symbiosis between soil living fungi and the roots of woody plants. EM fungal communities are important in forest nutrient cycling, they are species rich and their structures vary between habitats and over time. READ MORE
