1. Functional Traits in Sphagnum
Sammanfattning : Peat mosses (Sphagnum) are ecosystem engineers that largely govern carbon sequestration in northern hemisphere peatlands. I investigated functional traits in Sphagnum species and addressed the questions: (I) Are growth, photosynthesis and decomposition and the trade-offs between these traits related to habitat or phylogeny?, (II) Which are the determinants of decomposition and are there trade-offs between metabolites that affect decomposition?, (III) How do macro-climate and local environment determine growth in Sphagnum across the Holarctic?, (IV) How does N2 fixation vary among different species and habitats?, (V) How do species from different microtopographic niches avoid or tolerate desiccation, and are leaf and structural traits adaptations to growth high above the water table?Photosynthetic rate and decomposition in laboratory conditions (innate growth and decay resistance) were related to growth and decomposition in their natural habitats.

2. Traits & Talks : Lessons about Personality and Deliberation from the Negotiations between Nelson Mandela and FW de Klerk
Sammanfattning : Compelling research in political psychology and personality psychology points to the significance of personality as a determinant of political behavior. Within a comprehensive framework for the study of personality in politics, the so-called Five-level Model (FLM), this thesis primarily focuses on the level of personality traits, where the well-established Five-factor model (the ‘Big Five’) is applied.

3. Shaping urban environments through human selection for plant traits
Sammanfattning : Cities, as home to the majority of the world’s people, are significant sites for addressing challenges of achieving sustainability and securing human wellbeing. Urban environments are complex social-ecological systems, and meeting these challenges requires better understandings of the interactions of social and ecological elements. LÄS MER
4. How the sensory ecology of the bumblebee affects their functional traits
Sammanfattning : Morphological traits are important for trait-based ecological studies as they allow for the prediction of biodiversity across the biosphere. Currently, the predictive power of trait-based ecology is not often applied to terrestrial arthropods, even though they provide us with important agricultural, ecological, and cultural value. LÄS MER
5. Linking functional traits and cultural ecosystem services in urban areas through human preferences
Sammanfattning : Urban areas are now the daily lived experience for the majority of the world’s people, and it is therefore important to explore what kind of ecological communities and corresponding ecosystem functions and services are being generated in these environments. Urban areas are shaped by a variety of factors, but arguably one of the most influential is that of people, in terms of how their preferences and active selective choices for biota play out in the landscape.
