1. Hybrid sterility and genetic incompatibilities in Ficedula flycatchers
Abstract : Although the theory behind the mechanisms generating intrinsic post-zygotic isolation is well established, very few concrete examples of genetic incompatibilities have been described, especially in vertebrates. Consequently, our understanding of the evolutionary forces shaping the appearance of genetic incompatibilities between natural populations and the overall role of genetic incompatibilities in the speciation process is limited.

2. 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
