1. Plants go with the flow : predicting spatial distribution of plant species in the boreal forest
Abstract : The main objectives of this thesis are to study if a topographic wetness index (TWI) could be used as a tool for predicting the spatial distribution of vascular plant species richness in the boreal forest as well as to study congruence in species richness between vascular plants, liverworts, mosses and lichens. A wetness index ln(a/tanβ) based on topography was used to assign a specific TWI-value to every 20 x 20m grid in two 25 km2 boreal forest landscapes (differing in average soil pH) in northern Sweden.

2. Urban types in rapidly urbanising cities
Abstract : One of the challenges confronting cities innon-industrialised countries today is the fact that cities aregrowing at unprecedented rates, sizes and densities. Growthtrends in these cities are largely unregulated. READ MORE

3. Measurement of the Dalitz Plot Distribution for η→π+π−π0 with KLOE
Abstract : The mechanism of the isospin violating η→π+π−π0 decay is studied in a high precision experiment using a Dalitz plot analysis. The process is sensitive to the difference between up and down quark masses. READ MORE

4. Regional and local variation in plant species richness
Abstract : In this thesis, I examine the variation in plant species richness along gradients of productivity and disturbance in grasslands and forest habitats in southern Sweden, and I compare the documented patterns with theoretical predictions. Moreover, I evaluate the relative importance of habitat quality and habitat configuration for the occurrence of field layer species in deciduous forests. READ MORE

5. Simulations of turbulent boundary layers with suction and pressure gradients
Abstract : The focus of the present licentiate thesis is on the effect of suction and pressure gradients on turbulent boundary-layer flows, which are investigated separately through performing numerical simulations.The first part aims at assessing history and development effects on adverse pressure-gradient (APG) turbulent boundary layers (TBL).
