TL;DR: This study provides a roadmap to the emerging field of speciation genomics by showing that the genomic landscape of species differentiation is highly heterogeneous with approximately 50 ‘divergence islands’ showing up to 50-fold higher sequence divergence than the genomic background.

TL;DR: It is concluded that the heterogeneous landscape of differentiation in Ficedula flycatchers evolves mainly as the result of background selection and selective sweeps in genomic regions of low recombination, and the necessity of incorporating linked selection as a null model to identify genome regions involved in adaptation and speciation is emphasized.

TL;DR: Criteria for proper inference of demographic histories using PSMC is evaluated and recommendations of using sequencing data with a mean genome coverage of ≥18X, a per‐site filter of ≥10 reads and no more than 25% of missing data are arrived at.

TL;DR: In this paper, a comparative population genomics framework that exploits emergent features of long-term linked selection is proposed to account for the temporal dynamics of differentiation landscapes, which can help overcome shortcomings of traditional genome scans for adaptive evolution.

TL;DR: The detected patterns are difficult to explain only by range expansions from separate LGM refugia close to the Mediterranean and suggest that some M. arvalis populations persisted during the LGM in suitable habitat further north and that the gradients in genetic diversity may represent traces of a more ancient colonization of Europe by the species.
