Preliminary scope of work
Understanding the mechanisms of speciation is a major goal of evolutionary biology. Population genomics becomes an increasingly important tool for this research field and allows to investigate mechanisms and genetic basis of species formation even in non-model organisms that are not amenable to classical laboratory crosses. The aim of this PhD project is to elucidate the genetic architecture of reproductive isolation between two closely related song bird species, the Common Nightingale (Luscinia megarhynchos) and the Thrush Nightingale (L. luscinia). Using novel genotyping approaches based on next generation sequencing and previously developed species-specific SNP markers, the student will genotype several hundreds of DNA samples from naturally occurring hybrid populations between the two nightingale species, already collected during our previous research. The obtained data will allow us to investigate genome-wide patterns of interspecific gene flow and identify genomic regions responsible for nightingale speciation. Furthermore, we will use admixture mapping to examine genetic basis of several traits that are likely to contribute to prezygotic as well as postzygotic reproductive isolation in nightingales. Combination of admixture mapping with genome-wide patterns of introgression will enable us to infer the importance of different reproductive barriers in nightingale speciation. The student will be mainly responsible for the laboratory part of the project. We expect a motivated student interested in population genetics and evolutionary biology with at least basic training in molecular genetic techniques.
