Abstract excerpt
1. Bound and total corticosteroid concentrations of yellow-bellied marmots (Marmota flaviventris) were lowest in May after emergence from hibernation and peaked in August prior to immergence. 2.

There was no consistent relationship between measures of population density and concentrations of corticosteroids; when a significant...
