1. Trädgårdsmästarens förökningsmetoder – schema och katalog över förökningsdelar vid vegetativ förökning av fleråriga örtartade växter
Sammanfattning : The purpose of this licentiate thesis is to gather and classify information about traditional vegetative propagation of perennial herbaceous plants. This thesis is the first, self-contained part of a survey of propagation methods used by horticulturists. LÄS MER
2. Transcriptional biomarkers of toxicity – powerful tools or random noise? : An applied perspective from studies on bivalves
Sammanfattning : Aquatic organisms are constantly at risk of being exposed to potentially harmful chemical compounds of natural or anthropogenic origin. Biological life can for instance respond to chemical stressors by changes in gene expression, and thus, certain gene transcripts can potentially function as biomarkers, i.e. LÄS MER
3. Effects of FODMAPs and gluten on irritable bowel syndrome- from self-reported symptoms to molecular profiling
Sammanfattning : Irritable bowel syndrome (IBS) is a complex disorder of gut-brain interactions. The diagnosis of IBS is based on subjective reporting of abdominal pain and altered bowel habits in the absence of any clinical alterations of the gut or other pathological conditions. LÄS MER
4. Genomic and morphological diversity of marine planktonic diatom-diazotroph associations : a continuum of integration and diversification through geological time
Sammanfattning : Symbioses between eukaryotes and nitrogen (N2)-fixing cyanobacteria (or diazotrophs) are quite common in the plankton community. A few genera of diatoms (Bacillariophyceae) such as Rhizosolenia, Hemiaulus and Chaetoceros are well known to form symbioses with the heterocystous diazotrophic cyanobacteria Richelia intracellularis and Calothrix rhizosoleniae.

5. Learning-by-modeling : Novel Computational Approaches for Exploring the Dynamics of Learning and Self-governance in Social-ecological Systems
Sammanfattning : As a consequence of global environmental change, sustainable management and governance of natural resources face critical challenges, such as dealing with non-linear dynamics, increased resource variability, and uncertainty. This thesis seeks to address some of these challenges by using simulation models. LÄS MER
