1. The spatial structure of genetic and morphometric variation in Corylus avellana (Betulaceae): pattern and scale
Sammanfattning : In the present thesis, I investigated the spatial structure of genetic and morphometric variation in the widespread wind-pollinated shrub Corylus avellana (L.) Betulaceae, hazel, and related the variation to geographic distribution and different spatial scales. LÄS MER
2. 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.
