1. Patterns of geographic variation in Silene section Elisanthe (Caryophyllaceae): hybridization and migrational history
Sammanfattning : Large-scale patterns of genetic variation in chloroplast (cp) and nuclear DNA in the widespread European herb species Silene latifolia and S. dioica were investigated using cpPCR-RFLPs, non-coding cpDNA sequences, AFLPs and sequences of the internal transcribed spacers (ITS) of nuclear ribosomal DNA (rDNA).

2. Phylogenetic Relationships of Silene sect. Melandrium and Allied Taxa (Caryophyllaceae), as Deduced from Multiple Gene Trees
Sammanfattning : This thesis focuses on phylogenetic relationships among some of the major lineages in Silene subgenus Behenantha (Caryophyllaceae) using DNA sequences from multiple, potentially unlinked gene regions from a large taxonomic and geographic sample. Both traditional phylogenetic analyses and a strategy to infer species trees and gene trees in a joint approach are used. LÄS MER
3. Phylogenetic Relationships, Biogeography and Species Delimitation: A case study on southern African Silene (Caryophyllaceae)
Sammanfattning : The primary aim of this thesis was to explore the phylogenetic relationships and historical biogeography of African members of the plant genus Silene (Caryophyllaceae), with special focus on the eight native southern African taxa. Three loci (the nuclear ribosomal internal transcribed spacer region, and the rps16 and matK regions from the plastid genome) generated using traditional Sanger sequencing were used to infer the phylogenetic positions of African taxa, while sequence data from 28 low copy nuclear loci were generated using the target capture method to explore shallow phylogenetic relationships within southern African taxa.
