Sexual selection. Are ducks impressed by drakes' display?K G McCracken
Institute of Arctic Biology and Department of Biology and Wildlife, University of Alaska Fairbanks, Fairbanks, Alaska 99775, USA
Nature 413:128. 2001....
Signatures of high-altitude adaptation in the major hemoglobin of five species of andean dabbling ducksKevin G McCracken
Institute of Arctic Biology, Department of Biology and Wildlife, and University of Alaska Museum, University of Alaska, Fairbanks, Alaska 99775, USA
Am Nat 174:631-50. 2009....- Parallel evolution in the major haemoglobin genes of eight species of Andean waterfowlK G McCracken
Institute of Arctic Biology, Department of Biology and Wildlife, University of Alaska Fairbanks, Fairbanks, AK 99775, USA
Mol Ecol 18:3992-4005. 2009..The patterns of parallel evolution observed in these waterfowl suggest that adaptation to high-altitude hypoxia has resulted from selection on unique but overlapping sets of one to five amino acid substitutions in each lineage... - Gene flow in the face of countervailing selection: adaptation to high-altitude hypoxia in the betaA hemoglobin subunit of yellow-billed pintails in the AndesKevin G McCracken
Department of Biology and Wildlife, Institute of Arctic Biology, University of Alaska Fairbanks
Mol Biol Evol 26:815-27. 2009..Heterozygous individuals may have a dispersal advantage if their hemoglobin has a wider range of function due to the presence of multiple protein isoforms with a mixture of different oxygen affinities... - Is homoplasy or lineage sorting the source of incongruent mtdna and nuclear gene trees in the stiff-tailed ducks (Nomonyx-Oxyura)?Kevin McCracken
Institute of Arctic Biology, Department of Biology and Wildlife, University of Alaska Fairbanks, Fairbanks, Alaska 99775 USA
Syst Biol 54:35-55. 2005..In the case of Oxyura, the answer to both questions may be no. Complete mtDNA sequences combined with data from a very large number of nuclear loci may be the only way to resolve such trichotomies... - Multilocus coalescent analysis of haemoglobin differentiation between low- and high-altitude populations of crested ducks (Lophonetta specularioides)Mariana Bulgarella
Department of Biology and Wildlife, Institute of Arctic Biology, and University of Alaska Museum, University of Alaska Fairbanks, Fairbanks, AK 99775, USA
Mol Ecol 21:350-68. 2012.... - Phylogenetic and structural analysis of the HbA (alphaA/betaA) and HbD (alphaD/betaA) hemoglobin genes in two high-altitude waterfowl from the Himalayas and the Andes: Bar-headed goose (Anser indicus) and Andean goose (Chloephaga melanoptera)Kevin G McCracken
Institute of Arctic Biology, Department of Biology and Wildlife, University of Alaska Fairbanks, Fairbanks, AK 99775, USA
Mol Phylogenet Evol 56:649-58. 2010..Our findings illustrate the importance of understanding phylogenetic relationships and polarity of character-state changes when making inferences about adaptive evolution... - Do common eiders nest in kin groups? Microgeographic genetic structure in a philopatric sea duckSarah A Sonsthagen
Institute of Arctic Biology and Department of Biology and Wildlife, University of Alaska Fairbanks, Fairbanks, AK 99775, USA
Mol Ecol 19:647-57. 2010..A long-term demographic study is needed to understand more fully the mechanisms that lead to fine-scale genetic structure observed in common eiders breeding in the Beaufort Sea... - Population structure and genetic diversity of moose in AlaskaJennifer I Schmidt
Institute of Arctic Biology, University of Alaska Fairbanks, 902 N Koyukuk Dr, Fairbanks, AK, 99775 7000, USA
J Hered 100:170-80. 2009..Finally, there was no evidence of bottlenecks either at the population level or overall. We conclude that weak population structure occurs among moose in Alaska with population expansion from interior Alaska westward toward the coast... 
Gene flow and hybridization between numerically imbalanced populations of two duck species in the Falkland IslandsKevin G McCracken
Institute of Arctic Biology, University of Alaska Museum, and Department of Biology and Wildlife, University of Alaska Fairbanks, Fairbanks, Alaska, United States of America
PLoS ONE 6:e23173. 2011....- Genetic and phenotypic divergence between low- and high-altitude populations of two recently diverged cinnamon teal subspeciesRobert E Wilson
Institute of Arctic Biology, Department of Biology and Wildlife, and University of Alaska Museum, University of Alaska Fairbanks, Fairbanks, Alaska 99775 E mail Department of Biological Sciences, Wright State University, Dayton, Ohio 45435
Evolution 67:170-84. 2013..Multiple selection pressures associated with high-altitude habitats, including cold and hypoxia, have likely shaped morphological and genetic divergence within South American cinnamon teal populations... - Movements of birds and avian influenza from Asia into AlaskaKevin Winker
University of Alaska Museum, Fairbanks, Alaska 99775, USA
Emerg Infect Dis 13:547-52. 2007....
