      The Bering Land Bridge (BLB) last connected Eurasia and North America during the Late Pleistocene. Although the BLB would have enabled transfers of terrestrial biota in both directions, it also acted as an ecological filter whose permeability varied considerably over time. Here we explore the possible impacts of this ecological corridor on genetic diversity within, and connectivity among, populations ...
    • Natural selection shaped the rise and fall of passenger pigeon genomic diversity 

      Murray, Gemma G.R.; Soares, André E.R.; Novak, Ben J.; Schaefer, Nathan K.; Cahill, James A.; Baker, Allan J.; Demboski, John R.; Doll, Andrew; Da Fonseca, Rute R.; Fulton, Tara L.; Gilbert, Marcus Thomas Pius; Heintzman, Peter D.; Letts, Brandon; McIntosh, George; O'Connell, Brendan L.; Peck, Mark; Pipes, Marie-Lorraine; Rice, Edward S.; Santos, Kathryn M.; Sohrweide, A. Gregory; Vohr, Samuel H.; Corbett-Detig, Russell B.; Green, Richard E.; Shapiro, Beth (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-17)
      The extinct passenger pigeon was once the most abundant bird in North America, and possibly the world. Although theory predicts that large populations will be more genetically diverse, passenger pigeon genetic diversity was surprisingly low. To investigate this disconnect, we analyzed 41 mitochondrial and 4 nuclear genomes from passenger pigeons and 2 genomes from band-tailed pigeons, which are ...
