  • [Post-print] The K = 2 conundrum 

    Janes, Jasmine K.; Miller, Joshua M.; Dupuis, Julian R.; Malenfant, René; Gorrell, Jamieson C.; Cullingham, Catherine I.; Andrew, Rose L. (John Wiley & Sons, Inc., 2017-07)
    Assessments of population genetic structure have become an increasing focus as they can provide valuable insight into patterns of migration and gene flow. STRUCTURE, the most highly cited of several clustering-based ...
  • Sexually selected infanticide by male red squirrels in advance of a mast year 

    Haines, Jessica A.; Coltman, David W.; Dantzer, Ben; Gorrell, Jamieson C.; Humphries, Murray M.; Lane, Jeffrey E.; McAdam, Andrew G.; Boutin, Stan (Ecological Society of America, 2018-05)
    North American red squirrels (Tamiasciurus hudsonicus) anticipate when white spruce (Picea glauca), their primary food source, will produce large amounts of cones in infrequent and irregular mast years (Boutin et al. 2006). ...
  • [Pre-print] Spatial and temporal assessments of genetic structure in an endangered Garry oak ecosystem on Vancouver Island 

    Catherall, Erin E.; Janes, Jasmine K.; Josefsson, Caroline A.; Gorrell, Jamieson C. (NRC Research Press, 2018-01-26)
    Garry oak (Quercus garryana Dougl. ex Hook.) is a deciduous tree whose ecosystem is listed “at-risk” throughout its range in British Columbia (B.C.), Canada, under the Canadian Species at Risk Act (SARA). Garry oak ...
  • Seasonal, spatial, and maternal effects on gut microbiome in wild red squirrels 

    Ren, Tiantian; Boutin, Stan; Humphries, Murray M.; Dantzer, Ben; Gorrell, Jamieson C.; Coltman, David W.; McAdam, Andrew G.; Wu, Martin (BioMed Central, 2017-12-21)
    Our understanding of gut microbiota has been limited primarily to findings from human and laboratory animals, but what shapes the gut microbiota in nature remains largely unknown. To fill this gap, we conducted a comprehensive ...
  • Phylogeography of a migratory songbird across its Canadian breeding range: Implications for conservation units 

    Haché, Samuel; Bayne, Erin M.; Villard, Marc-André; Proctor, Heather; Davis, Corey S.; Stralberg, Diana; Janes, Jasmine K.; Hallworth, Michael T.; Foster, Kenneth R.; Chidambara-vasi, Easwaramurthyvasi; Grossi, Alexandra A.; Gorrell, Jamieson C.; Krikun, Richard (John Wiley & Sons, Inc., 2017-06-28)
    The objectives of this study were to describe and evaluate potential drivers of genetic structure in Canadian breeding populations of the Ovenbird, Seiurus aurocapilla. We performed genetic analyses on feather samples ...
  • Voyage of discovery? A comment on Koch et al. "A voyage to Terra Australis: human-mediated dispersal of cats" 

    Andrew, Rose L.; Smith, Deane; Gorrell, Jamieson C.; Janes, Jasmine K. (BioMed Central, 2016-12-07)
    The origins of feral cats in Australia may be understood with the help of molecular studies, but it is important that hypotheses be tested with appropriate sampling and methodology. We point out several shortcomings in ...
  • Very low levels of direct additive genetic variance in fitness and fitness components in a red squirrel population 

    McFarlane, S. Eryn; Gorrell, Jamieson C.; Coltman, David W.; Humphries, Murray M.; Boutin, Stan; McAdam, Andrew G. (John Wiley & Sons, Inc., 2014-05)
    A trait must genetically correlate with fitness in order to evolve in response to natural selection, but theory suggests that strong directional selection should erode additive genetic variance in fitness and limit future ...
  • Adopting kin enhances inclusive fitness in asocial red squirrels 

    Gorrell, Jamieson C.; McAdam, Andrew G.; Coltman, David W.; Humphries, Murray M.; Boutin, Stan (Macmillan Publishers Ltd., 2010-06-01)
    Orphaned animals benefit from being adopted, but it is unclear why an adopting parent should incur the costs of rearing extra young. Such altruistic parental behaviour could be favoured if it is directed towards kin and ...
