My PhD project (DFG 413417083) aims at uncovering the genetic basis and evolutionary history of phenotypic and species evolution in a color-polymorphic songbird radiation, wheatears (genus Oenanthe) and relatives. To study these questions, in a first part of my project, I will reconstruct the histories of colonization and hybridization in pervasively hybridizing wheatear species, before inferring genome regions that are shielded from gene flow and represent candidate genomic regions involved in reproductive isolation. In a second part, I will use an admixture mapping approach and comparative genomic analyses to infer genomic regions involved in the parallel evolution of plumage color traits.
