11. Population genetic analyses in the orchid genus Gymnadenia : a conservation genetic perspective
Abstract : 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. READ MORE

12. Effects of Social Organisation on Spatial Genetic Structures in Formica Ants
Abstract : The social organization of social insect colonies can be broadly defined as monogynous, single reproductive female or polygynous, several reproductive females. Monogynous organization is genetically simple while polygynous is more complex and the two social forms differ commonly in mating and dispersal behaviour as well as in colony foundation. READ MORE

13. Hybrid zones and speciation – insights from the European crow hybrid zone
Abstract : In hybrid zones genetically differentiated populations meet and interbreed. As they result from ongoing divergence and potential speciation, such zones provide opportunities to study how different factors affect this process. The hybrid zone between the all black carrion crow (Corvus corone corone) and the grey and black hooded crow (Corvus c. READ MORE

14. Conservation Genetics of the White-Tailed Eagle
Abstract : The white-tailed eagle is a formerly threatened raptor that is commonly used as a flagship and indicator species in conservation work. This thesis uses molecular genetic methods to study sex determination of nestlings, genetic variability, population structure and phylogeography of the white-tailed eagle. READ MORE

15. Effects of Agriculture on Abundance, Genetic Diversity and Fitness in the Common Frog, Rana temporaria
Abstract : The aims of this thesis were to evaluate the effects of agriculture on amphibians in terms of (i) population genetic consequences of agriculture-induced spatial changes of the landscape and (ii) local adaptation and tolerance to frequently used agrochemicals. The study was performed using the common frog Rana temporaria as a model. READ MORE
