a Body temperature trace showing a 13-lined ground squirrel’s year. Hibernating portion is demarcated by blue shaded box above. b A non-hibernating and hibernating 13-lined ground squirrel, individually housed in standard lab rodent cages in an animal facility. c Representative plots of body temperature telemetry analyses. Arrows point to the first day of torpor, the phenotype measured in this study. Days are ± from hibernaculum placement. d Approximate locales of squirrels genotyped in this study. The taupe shaded area indicates the 13-lined ground squirrel’s geographic range with data provided by NatureServe76. The map was created using ggmap77 for R.
