Development and utilization of implantable cardiac monitors in free-ranging American black and Eurasian brown bears: System evolution and lessons learned
Biologgers can be used to monitor both human and animal physiology and behaviors, activity patterns, and/or environmental stressors. Monitoring of heart rates and rhythms, respiratory patterns, and activity in free-ranging bears can provide unique insights into physiological mechanisms. Such researc...
