31. Population differentiation in Lythrum salicaria along a latitudinal gradient
Sammanfattning : In this thesis, quantitative genetic approaches, common-garden experiments, and field studies were combined to examine patterns of population differentiation and the genetic architecture of characters of putative adaptive significance in the widely distributed perennial herb Lythrum salicaria. In this work, I (1) documented patterns of population differentiation in phenology, life-history, and morphology along latitudinal gradients at different geographical scales, (2) investigated the genetic architecture of phenology, flower morphology, and inflorescence size, and (3) combined estimates of phenotypic selection in the field with information on the genetic variance-covariance matrix (G) to examine potential constraints to adaptive evolution.

32. Management regimes for lawns and hedges in historic gardens
Sammanfattning : Management regimes for lawns and hedges in historic gardens This research investigates and compares eighteenth-century and contemporary garden management methods with a focus on the structural elements of lawns and hedges at Gunnebo House, which is used as a craft laboratory. The concept of management regime is utilized for a discourse analysis of the garden through the norms embedded in the management. LÄS MER
33. Molecular population genetics of inducible defense genes in Populus tremula
Sammanfattning : Plant-herbivore interactions are among the most common of ecological interactions. It is therefore not surprising that plants have evolved multiple mechanisms to defend themselves, using both constitutive chemical and physical barriers and by induced responses which are only expressed after herbivory has occurred.

34. Isak Gustaf Clasons herrgårdsrestaureringar 1888–1930
Sammanfattning : Manor house restorations by isak Gustaf Clason 1888–1930 Swedish architect Isak Gustaf Clason (1856–1930) was the leading expert of his time for the conservation of manor houses and also for designing new manor houses and large villas. He was considered a leader for the architectural community and worked with many different types of building projects. LÄS MER
35. Intraspecific variation in Rhinanthus angustifolius. Local adaptation, phenotypic plasticity and geographical structure
Sammanfattning : Plant species often adapt to local environmental conditions, which can result in the formation of genetically and phenotypically distinct ecotypes. Ecotypes can evolve rapidly, and may be a first step in the process of ecological speciation. LÄS MER
