This protocol uses juvenile American lobsters as a model to demonstrate the use of impedance pneumography to assess physiological performance during a thermal stress. This technique passes a small oscillating electrical current across two electrod

Measuring heart rate during a thermal challenge provides insight into physiological responses of organisms as a consequence of acute environmental change. Using the American lobster (Homarus americanus) as a model organism, this protocol describes the use of impedance pneumography as a relatively noninvasive and nonlethal approach to measure heart rate in late stage invertebrates.
