1. Detection of spatial genetic structure and identification of conservation units in continuous environments
Sammanfattning : .... LÄS MER
2. Assessing and monitoring genetic patterns for conservation purposes with special emphasis on Scandinavia
Sammanfattning : Genetic variation is essential for biological evolution, for maintaining viability of populations, and to ensure ecosystem resilience. Increased human exploitation and environmental change result in rapid loss of biological variation, including genetic diversity. LÄS MER
Sammanfattning : The overall objective of this thesis is to provide a background to the recycling of cotton. Since cotton consists of pure cellulose, it might be possible to include used cotton, in the already existing viscose industry. LÄS MER
4. Evolutionary history and chloroplast DNA variation in three plant genera: Betula, Corylus and Salix. : The impact of post-glacial colonisation and hybridisation
Sammanfattning : The great difference in the level of chloroplast variation and its geographic structure among the three main species studied here demonstrates that forest species do not form a homogeneous group. Hazel shows a genetic structure similar to many other thermophilous species and this structure, in combination with fossil evidence, indicates that the post-glacial colonisation of most of Europe originated in a refugium in western France while the Balkan and Italy were colonised from a south-eastern refugium.

Sammanfattning : In many parts of the world, there are well-established systems for material recycling of metal, glass, and paper. However, no large-scale chemical recycling of textiles currently exists. LÄS MER
