Not All Networks are Created Equal
One of the benefits of social network models is that it allows for a visual and quantitative comparison to elucidate differences in social structure between species or populations. However, if scientists are not careful, differences may be a result of methodology, and not social relationships.

Genomics of Incipient Speciation
This paper (sub) compares genome-wide SNPs between two Swainson’s thrush subspecies. The subspecies have different breeding and wintering grounds, migration routes, plumage colors, and songs. The authors observed 65 genes in genomic islands with high divergence between the two species. From the candidate gene pool genes associated with migration, color, and song were identified, where the color and song genes may be different due to drift but the migration associated gene may have been selected upon.
