Abstract

This study performs biological and physiological validations of a minimally-invasive technique for assessing fecal corticosterone metabolites in captive and wild groups of yellow-bellied marmots and finds repeatable inter-individual differences in FCMs, suggesting this hormonal trait might be a meaningful target of selection.
