Neues wagen, Positives entdecken, jeden Tag. This thesis is based on the following three publications and manuscripts. They will be referred
to in the text by the term ‘paper’ and their roman numerals. They are reviewed in chapter 2
and 3 of this thesis. After a short general introduction into the main topics, the main results of
the respective scientific analyses are given and interpreted. For detailed information about
materials and methods as well as for further results and discussions see appended
publications and manuscripts.
I Genetic support for recurrent fragmentation and founder events of juniper
populations in Central Europe
Inga M. Michalczyk, Yvonne A. Lücke, Stefan Huck and Birgit Ziegenhagen
Manuscript submitted to The Holocene.
Reviews received with the comment ‘possibly acceptable after moderate revision’.
II Characterization of highly polymorphic nuclear microsatellite loci in Juniperus
communis L.
Inga M. Michalczyk, Federico Sebastiani, Anna Buonamici, Eva Cremer, Christina
Mengel, Birgit Ziegenhagen and Giovanni G. Vendramin
Molecular Ecology Notes (2006) 6, 346-348.
III Reduction of population sizes has not yet affected genetic diversity of juniper,
Juniperus communis L.
