    • 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 ...
    • [Pre-print] Sex- and context-specific associations between personality and a measure of fitness but no link with life history traits 

      Haines, Jessica A.; Nason, Sarah E.; Skurdal, Alyshia M.M.; Bourchier, Tenal; Boutin, Stan; Taylor, Ryan W.; McAdam, Andrew G.; Lane, Jeffrey E.; Kelley, Amanda D.; Humphries, Murray M.; Gorrell, Jamieson C.; Dantzer, Ben; Coltman, David W.; Hämäläinen, Anni (Elsevier, 2020-07-23)
      The pace-of-life syndrome hypothesis posits that personality traits (i.e. consistent individual differences in behaviour) are linked to life history and fitness. Specifically, fast-paced individuals are predicted to be ...
    • 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 ...
    • 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). ...
    • 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 ...
