1. Climate change time machine : Adaptation to 30 years of warming in the Baltic Sea
Sammanfattning : Earth mean surface temperature has increased by 1 °C since the industrial revolution, and this has already had considerable effects on animal and plant species. Ecological responses to the warming climate – often facilitated via phenotypic plasticity – are ubiquitous. LÄS MER
2. Evolutionary innovation : Early industrial uses of genetic engineering
Sammanfattning : Based on an analysis of biological and economic theories of evol~tion, this dissertation first specifies evolutionary innovation and then uses it toanalyze early industrial uses of genetic engineering. Innovation refers totechnological innovation processes, i.e. series of innovative activitiesresulting in technical change. LÄS MER
3. Drivers of evolutionary change in Podospora anserina
Sammanfattning : Genomic diversity is shaped by a myriad of forces acting in different directions. Some genes work in concert with the interests of the organism, often shaped by natural selection, while others follow their own interests. The latter genes are considered “selfish”, behaving either neutrally to the host, or causing it harm. LÄS MER
4. Bank-Industry Networks and Economic Evolution : An Institutional-Evolutionary Approach
Sammanfattning : The links between institutions and economic evolution, especially between financial institutions and industrial innovation, are poorly understood. Having Schumpeter´s theory of economic evolution as starting point, this study gives an outline of an institutional-evolutionary theory of institutional change, innovation, and financial systems, based on learning-by-financing within bank-industry networks.

5. Plant-Herbivore Interactions and Evolutionary Potential of Natural Arabidopsis lyrata Populations
Sammanfattning : In this thesis, I combined field, greenhouse and common-garden experiments to examine the ecological and evolutionary consequences of plant-herbivore interactions and the genetic architecture of fitness-related traits in the insect-pollinated, self-incompatible, perennial herb Arabidopsis lyrata. More specifically, I examined (1) whether damage to leaves and inflorescences affects plant fitness non-additively, (2) whether trichome production is associated with a cost in terms of reduced tolerance to leaf and inflorescence damage, (3) whether young plant resistance to a specialist insect herbivore varies among populations, and (4) whether the evolution of flowering time, floral display and rosette size is constrained by lack of genetic variation or by genetic correlations among traits.
