Annual trends in heart rate (HR), activity, and heart rate variability (HRV) recorded from a female black bear in Minnesota denning with yearlings in 2009 and birthing cubs in January of 2010. These data were recorded with a Generation 2 (GEN 2) device with conventional human clinical software. A steady increase in HR and activity occurs through the spring with a sharp decrease in the fall prior to hibernation. A transient increase in HR and activity is seen just prior to parturition, with cessation of activity occurring immediately after (see inset)
