a, Design and construction of IR assay arena. b, Diagram of Peltier plates and recording camera position in the IR assay arena (image shown with one side wall removed for clarity). c, Schematic of assay cage used in IR behaviour experiments. The clear acrylic panel is shown in grey. d, Perforated tubing surrounding the two Peltier plates. e, Concentrations of CO2 recorded from a CO2 sensor placed inside an assay cage and exposed to the 5-minute CO2 paradigm used in the study. There were no differences in CO2 concentration in the left and right zones. Means ± SEMs (n = 3 independent measurements). f, Infrared thermograph of the thermal output of each zone of the IR source used in the distance setup. The right zone was held at ~34 °C, while the left zone was allowed to equilibrate with the ambient incubator conditions. Image acquisition and temperature estimation were made using a FLIR One infrared smartphone camera.
