Regressions between molt period δD_fur and growing season δD_precip or latitude at the collection sites.

<p>The δD_fur values (site mean ± standard deviation) of males collected during the molt period varied significantly with latitude of capture (panel A) and predicted growing season δD_precip at the location of capture (panel B). The same was true of female molt period δD_fur values and latitude (panel C) and δD_precip (panel D). <i>n</i> = 1 to 7 individuals per site. Predicted growing season δD_precip values were obtained from waterisotopes.org <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031419#pone.0031419-Bowen1" target="_blank">[40]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031419#pone.0031419-Bowen3" target="_blank">[44]</a>.
