1. Reproductive isolation at contact zones
Sammanfattning : Speciation is among the most important evolutionary processes that contribute to biodiversity. It involves the formation of new species that have become reproductively isolated through a process that is not linear and varies in time and space. LÄS MER
2. Population genetic analyses in the orchid genus Gymnadenia : a conservation genetic perspective
Sammanfattning : Small populations are facing a particular risk of extinction due to a lack of appropriate genetic diversity and associated negative effects, factors dealt with in the discipline of conservation genetics. Many orchid species exhibit characteristics that make them a perfect study object in the scope of conservation genetics. LÄS MER
3. Female reproductive strategies and sexual conflicts in a polygynous mating system
Sammanfattning : In this thesis, I have investigated conflicts of interest in the facultatively polygynous European starling (Sturnus vulgaris) with a focus on female reproductive strategies. The extent to which males provided parental care was a key issue in understanding the mating system of the starling. LÄS MER
4. Mating system evolution and self-incompatibility in the wild plant species Brassica cretica
Sammanfattning : Compared to animals like ourselves, plants have a very flexible sexual life. Most plants are, for example, hermaphrodites with the potential capacity for reproduction by self-fertilization (or selfing). LÄS MER
5. Chemical communication in mating shore crabs Carcinus maenas
Sammanfattning : Locating and evaluating a suitable partner for mating is one of the most important events in any sexually reproducing organism. To achieve this, an animal must be able to locate its partner over both long and short distances, and finally evoke the proper mating behaviour. LÄS MER
