Journal ArticleDOI
Genomic variation across two barn swallow hybrid zones reveals traits associated with divergence in sympatry and allopatry.
Elizabeth S. C. Scordato,Matthew R. Wilkins,Matthew R. Wilkins,Georgy A. Semenov,A. S. Rubtsov,Nolan C. Kane,Rebecca J. Safran +6 more
TL;DR: Traits associated with genome‐wide differentiation in allopatry may also contribute to isolation in sympatry, and potentially important additional roles for evolutionary history and ecology in shaping variation in the extent hybridization between closely related pairs of subspecies are discussed.
Journal ArticleDOI
Biological introduction risks from shipping in a warming Arctic
Chris Ware,Chris Ware,Jørgen Berge,Jørgen Berge,Anders Jelmert,Steffen M. Olsen,Loïc Pellissier,Mary S. Wisz,Darren J. Kriticos,Georgy A. Semenov,Sławomir Kwaśniewski,Inger Greve Alsos +11 more
TL;DR: Risks associated with non-indigenous propagule loads discharged with ships' ballast water to the high-Arctic archipelago, Svalbard, are evaluated as a case study for the wider Arctic and show that current ballastWater management practices do not prevent non-Indigenous species from being transferred to the Arctic.
Journal ArticleDOI
Limited Phylogeographic Signal in Sex-Linked and Autosomal Loci Despite Geographically, Ecologically, and Phenotypically Concordant Structure of mtDNA Variation in the Holarctic Avian Genus Eremophila
TL;DR: It is argued that mtDNA is capable of discovering independent evolutionary units within avian taxa and can provide a reasonable phylogeographic hypothesis when geographic scale, geologic history, and phenotypic variation in the study system are too complex for proposing reasonable a priori hypotheses required for multilocus methods.
Journal ArticleDOI
Geographic mode of speciation in a mountain specialist Avian family endemic to the Palearctic
Sergei V. Drovetski,Georgy A. Semenov,Sofya S. Drovetskaya,Igor V. Fadeev,Yaroslav A. Red'kin,Gary Voelker +5 more
TL;DR: Allopatric speciation is the predominant geographic mode of speciation in Prunellidae despite the favorable conditions for ecological diversification in the mountains and range overlaps among species.
Journal ArticleDOI
Effects of assortative mate choice on the genomic and morphological structure of a hybrid zone between two bird subspecies.
Georgy A. Semenov,Elizabeth S. C. Scordato,David R. Khaydarov,Chris C. R. Smith,Nolan C. Kane,Rebecca J. Safran +5 more
TL;DR: The results emphasize that assortative mating may maintain phenotypic differences independent of other processes shaping genome‐wide variation, consistent with other recent findings that raise questions about the relative importance of mate choice, ecological selection and selectively neutral processes for divergent evolution.
