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: A draft assembly of the non-recombining region of the collared flycatcher W chromosome is presented, containing 46 genes without evidence of female-specific functional differentiation, demonstrating evolutionary stable matrilineal inheritance of this nuclear–cytonuclear pair of chromosomes.

TL;DR: This study of a young vertebrate speciation model system expands knowledge of how gene expression evolves as natural populations become reproductively isolated by identifying genes differentially expressed between species and finding 16 genes uniquely expressed in one of the species.

TL;DR: A model of compensation occurring on a gene-by-gene basis is supported, supported by an absence of clustering of genes on the Z chromosome with respect to the extent of compensation, which suggests male-biased expression of Z-linked genes is a derived trait after avian sex chromosome divergence.

TL;DR: A large number of single nucleotide polymorphisms as well as estimates of gene expression on transcriptome scale are yielded and the synonymous substitution rate per year is found to be an order of magnitude smaller than values reported for angiosperm herbs.
