Behavioral and Physiological Responses of Ozark Zigzag Salamanders to Stimuli from an Invasive Predator: The Armadillo
Figure 5
Experiment 3: physiological responses to substrate cues. Oxygen consumption index by salamanders exposed to stimuli from armadillos, deer, or blank control water in a closed chamber for 12 min. Bars and error bars represent means ± 1 SE. The asterisk represents statistical significance. Index = residuals of log-transformed oxygen consumption (L) regressed against log-transformed mass (g).
