16. Speciation - What Can be Learned from a Flycatcher Hybrid Zone?
Abstract : Studies of hybrid zones offer important insights into the process of speciation. Much of the knowledge to be gained is dependent on an accurate estimation of the strength of pre- and post-zygotic isolation between hybridizing taxa. My results demonstrate that hybridization can variously affect different components of fitness. READ MORE

19. Nanofabrication of Zone Plates for Hard X-Ray Free-Electron Lasers
Abstract : This Thesis describes the development of hard X-ray zone plates intended for focusing radiation at X-ray free-electron lasers (XFELs). XFELs provide unprecedented brightness and zone plates which are put in the intense X-ray beam are at risk of being damaged. READ MORE

20. 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
