Published in 2021 at "General and comparative endocrinology"

DOI: 10.1016/j.ygcen.2021.113837

Abstract: Analysis of hair cortisol concentrations (HCCs) is a promising method for monitoring long-term stress in mammals. However, previous measurements of HCCs in polar bears (Ursus maritimus) have yielded highly variable results, which are likely due… read more here.
