Phylogenetic Inference and Allopolyploid Speciation - A Study of Silene section Physolychnis
(2012-08-31)
The major theme of this thesis is allopolyploidization, with focus on Silene section Physolychnis. The evolutionary history of an allopolyploid species can be established by inferring the sister relationships of the ...

(2012-09-27)
Phytoplankton are the most important primary producers in the world’s oceans, yet little is known of how they avoid the constant threats from the pelagic grazers. From land it is well known that plants defend themselves ...
Biofilms in Nitrogen Removal - Bacterial Population Dynamics and Spatial Distribution
(2012-01-12)
Efficient nitrogen removal at wastewater treatment plants (WWTPs) is necessary to avoid
eutrophication of recipient waters. The most commonly used approach consists of aerobic
nitrification and subsequent anaerobic ...
