Group of Population and Speciation Genetics



Research

We focus our research on the genetics and ecology of speciation in two song bird species - the Common Nightingale (Luscinia megarhynchos) and Thrush Nightingale (L. luscinia) - which hybridize in a secondary contact zone spanning Central and Eastern Europe. We study the evolution of reproductive isolation at all levels, including premating, postmating-prezygotic and postzygotic barriers to gene flow. Combining population, quantitative and functional genomics we aim to elucidate the genetic architecture of reproductive isolation and identify molecular mechanisms and specific genes responsible for the establishment of reproductive isolation. We are particularly interested in the role of sex chromosomes in speciation. Genetic studies are complemented by analyses of morphological, ecological and behavioral data to understand how hybridization and competition between species affect the process of speciation.
