Field Physiology: Studying Organismal Function in the Natural Environment

Area of Science:

• Physiology
• Animal Behavior
• Ecology

Background:

• Understanding free-ranging animal physiology requires continuous field measurements.
• Baseline physiology, variability, and responses to disturbances are key research areas.

Purpose of the Study:

• To review current technologies for high-resolution, continuous physiological monitoring in freely behaving animals.
• To discuss advantages, disadvantages, and emerging technologies for field physiology.
• To focus on heart rate and body temperature monitoring methods.

Main Methods:

• Review of existing technologies: radio telemetry (VHF/UHF), acoustic telemetry, and dataloggers.
• Analysis of physiological parameters measured: heart rate (ECG), EMG, EEG, body temperature, oxygen levels, gastric pH, and blood pressure.
• Discussion of emerging technologies and future innovations.

Main Results:

• Various telemetry and datalogger systems are available for field physiological monitoring.
• Heart rate and body temperature are extensively studied parameters in free-ranging organisms.
• Emerging technologies show promise for future high-resolution field studies.

Conclusions:

• Continuous field monitoring provides crucial insights into animal physiology.
• Careful experimental design and consideration of animal welfare are essential.
• Future innovations will enhance the scope and resolution of physiological data from wild animals.
