A summary of δ2Hfur values with respect to season of sampling, stable isotope laboratory, and of δ2Hprecip at site of sampling. Panel A shows the δ2Hfur (‰, VSMOW-SLAP) values for known-origin summer bat fur analyzed at the University of Western Ontario (UWO; n = 78) and Central Appalachian Stable Isotope Facility (CASIF; n = 37) respectively, alongside unknown-origin winter bat fur analyzed at CASIF (n = 111). Panel B shows the inferred relationship between δ2Hprecip (top-performing isoscape was a June–August δ2Hprecip model, IsoMAP job 66,098) and known-origin summer δ2Hfur (‰, VSMOW-SLAP). The results of a bootstrapped linear regression, with subsampling iterated with respect to sampling site, are reported below, with mean parameter estimates plotted on the scatter plot
