Effects of asymmetric nuclear introgression, introgressive mitochondrial sweep, and purifying selection on phylogenetic reconstruction and divergence estimates in the pacific clade of Locustella Warblers
Drovetski, Sergei V.; Semenov, Georgy; Red'kin, Yaroslav A.; Fadeev, Igor V.; Koblik, Eugeniy A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-07)When isolated but reproductively compatible populations expand geographically and meet, simulations predict asymmetric introgression of neutral loci from a local to invading taxon. Genetic introgression may affect phylogenetic reconstruction by obscuring topology and divergence estimates. We combined phylogenetic analysis of sequences from one mtDNA and 12 nuDNA loci with analysis of gene flow ... -
Geographic mode of speciation in a mountain specialist avian family endemic to the Palearctic
Drovetski, Sergei V.; Semenov, Georgy; Drovetskaya, Sofya S.; Fadeev, Igor V.; Red'kin, Yaroslav A.; Voelker, Gary (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Mountains host greater avian diversity than lowlands at the same latitude due to their greater diversity of habitats stratified along an elevation gradient. Here we test whether this greater ecological heterogeneity promotes sympatric speciation. We selected accentors (Prunellidae), an avian family associated with mountains of the Palearctic, as a model system. Accentors differ in their habitat/elevation ... -
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
Drovetski, Sergei V.; Rakovic, Marko; Semenov, Georgy; Fadeev, Igor V.; Red'kin, Yaroslav A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)Phylogeographic studies of Holarctic birds are challenging because they involve vast geographic scale, complex glacial history, extensive phenotypic variation, and heterogeneous taxonomic treatment across countries, all of which require large sample sizes. Knowledge about the quality of phylogeographic information provided by different loci is crucial for study design. We use sequences of one mtDNA ... -
MtDNA ND2 sequence identifies Streaked Horned Lark (Eremophila alpestris strigata) from birdstrike to US Air Force F-15 at Portland International Airport, Oregon
Dove, Carla J.; Dahlan, Nor Faridah; Drovetski, Sergei V. (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)The Streaked Horned Lark (SHL: Eremophila alpestris strigata) is the Northwest subspecies of the Horned Lark listed as endangered in Washington State, critical in Oregon, and is now being considered for listing as threatened by the US Fish & Wildlife Service. Some of the important breeding areas of SHL are associated with airports in western Washington and Oregon which raises concern over possible ...
