1. Genetic variation, clonal diversity and breeding system in sedges (Carex)
Abstract : In this thesis I investigate genetic variation in clonal plants within the wind-pollinated plant family Cyperaceae and, in particular, in species of Carex. Clonal diversity and the spatial distribution of clones (genets) within populations was investigated in Carex bigelowii (in Iceland and Scandinavia) and C. READ MORE

2. Genetics and ecology of natural populations
Abstract : I have studied the genetic variation of single species using morphological variation and enzyme electrophoresis. I have striven to understand the interaction between the breeding structure and the ecology of the species in relation to the community, in which it lives. The work was done in the county of Västerbotten, northern Sweden. READ MORE

3. Molecular analysis of the oral microbiota of dental diseases
Abstract : Traditionally, bacterial culture has been used for bacterial detection, allowing study of living microorganisms. Molecular methods are rapid and allow simultaneous identification of numerous species and uncultivated phylotypes. READ MORE

4. Characterization of the Intestinal Microbiota by DNA-Based Methods
Abstract : The intestinal flora and the bacteria found in the extraintestinal sites were studied in liver injury rats, with or without Lactobacillus plantarum 299v pre-treatment. The dominating intestinal flora and translocating bacteria were typed by RAPD and identified by 16S rDNA sequencing. READ MORE

5. Nitrogen fixation among marine bacterioplankton
Abstract : While bacterioplankton indisputably control vital biogeochemical paths in the cycling of carbon and nutrients in the world’s oceans, our knowledge about the functional and genetic diversity of bacterioplankton communities is negligible. In this thesis, molecular and more traditional microbiological methods were used to study the specific function of N2-fixation and in a general sense diversity of marine bacterioplankton species.
