Relaxing life of the city? Allostatic load in yellow-bellied marmots along a rural–urban continuum

We measured fecal glucocorticoid metabolites (FGMs), an indicator of an animal’s response to stress, in yellow-bellied marmots along a rural–urban continuum. Our findings suggest that adult marmots are less stressed in urban environments compared to rural ones, while young are more stressed in rural environments than urban ones.
