On Speciation in Birds – Genomic Signatures across Space and Time

The process of speciation is a cornerstone in evolutionary biology. In Darwin’s On the Origin of Species, he described how he imagined that a new species would evolve to fill an empty niche. This focus on ecology shifted with Mayr towards the importance of isolation, and for many decades the geographic modes of speciation were debated. Speciation in sympatry, i.e. without any isolation between the

The prey perspective - behaviour and appearance in a world of predators

The varieties of prey phenotypes that have been revealed in nature are vast and many of these phenotypes are the result of the selective force that predators have had on prey traits in the past. Even within species and populations we see variations due to both differences in the selection forces they live under but also due to individual trait variation. In this thesis I investigate both the direc

Tendon autografts for bridging nerve defects

A new method, where a tendon segment – a tendon autograft – was used as graft material for peripheral nerve reconstruction, was developed. Defects, 10-15 mm long, in rat sciatic nerves were bridged by various modifications of tendons. A piece of an intact tendon and a tendon, that had been teased into a membrane and then rolled to form a loose “collagen roll”, supported axonal regeneration over a

Glaucoma Characteristics and Risk Factors - Results from Malmö Eye Survey

This thesis is based on data from a large glaucoma screening, comprising 32, 918 elderly citizens of Malmö and data from retrospective analysis of glaucoma patients’ charts from the Eye Department of Malmö University Hospital. The definition of glaucoma was based on reproducible visual field defects and/or glaucomatous optic nerve head damage in both groups. In paper I, including screened individ

Health Effects of Foods Enriched with Cereal beta-Glucans from Cereals

Since soluble fibre in the form of the cereal beta-glucans found in oats and barley has been shown to have a positive effect on lipid and glucose metabolism, people at risk of developing cardiovascular diseases or diabetes might benefit from that a variety of palatable food products containing beta-glucans being available to them. The aim of the papers presented in the thesis was to evaluate the m

Application of the Fluoresecence Lidar Techniques in the Architectural Heritage

The primary aim of the research project is to analyse the potential for the application of lidar and fluorescence techniques in building investigation, and also to establish a scientific remote-sensing method for surveying and analysing the historical facade that is non-destructive and can be used in-situ. The fluorescence lidar method uses point-monitoring and scanning of areas that can provide m
