    • A detailed life history of a Pleistocene steppe bison (Bison priscus) skeleton unearthed in Arctic Alaska 

      Funck, Juliette; Heintzman, Peter D.; Murray, Gemma G.R.; Shapiro, Beth; McKinney, Holly; Huchet, Jean-Bernard; Bigelow, Nancy H; Druckenmiller, Patrick; Wooller, Matthew J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-12)
      Detailed paleoecological evidence from Arctic Alaska’s past megafauna can help reconstruct paleoenvironmental conditions and can illustrate ecological adaptation to varying environments. We examined a rare, largely articulated and almost complete skeleton of a steppe bison (<i>Bison priscus</i>) recently unearthed in Northern Alaska. We used a multi-proxy paleoecological approach to reconstruct the ...

    • 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.

      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 ...
