6. The role of regeneration in plant niche differentiation and habitat specialization
Sammanfattning : To predict the effects of environmental change and nature management on the distribution of plant species, it is crucial to understand the mechanisms of plant niche differentiation and habitat specialization. The importance to habitat specialization of particular plant traits and requirement of the regenerative phase of the plants life has received scanty interest. LÄS MER
7. Bottom-up and top-down regulation of heterogeneous lake food webs
Sammanfattning : Food webs are networks of organisms linked by trophic interactions that regulate the responses of ecosystems to environmental change. Such regulation is a result of the effects of resources on the abundance of their consumers (i.e. bottom-up effects) and/or the influence of consumers on the abundance of their resources (i. LÄS MER
8. Hidden Diversity Revealed : Genomic, Transcriptomic and Functional Studies of Diplomonads
Sammanfattning : The diplomonads are a diverse group of eukaryotic microbes found in oxygen limited environments such as the intestine of animals were they may cause severe disease. Among them, the prominent human parasite Giardia intestinalis non-invasively colonizes the small intestine of humans and animals where it induces the gastrointestinal disease giardiasis. LÄS MER
9. Neuroethology of olfaction in Drosophila : evolution and specialization
Sammanfattning : In insects olfaction is a primary sensory modality. As a result changes in the animal’s ecology are often paralleled by modifications in the olfactory system. Using a comparative approach between the generalist Drosophila melanogaster and its sibling specialist D. sechellia, I looked at the coding properties of the olfactory system. LÄS MER
10. Empirical essays on Regional Specialization and Trade in Sweden
Sammanfattning : This thesis deals with the empirical testing of trade theories, traditionally used to analyze international trade, using regional data on production and trade. This thesis consists of three main essays. In the first essay, we analyze Swedish regional production. LÄS MER
