Figure 6


Fig. 6. (A) Occurrence of CO2 pulses from zero and non-zero baseline CO2 in one specimen of Pterostichus stygicus. `Singlet' pulses (indicated with grey arrows) were stand-alone bursts of CO2 that occurred with a tracheal compression. Such singlets did not occur in any other specimen. The inset box shows the area (red) used to calculate the volume of all other pulses. Beetle, mass 178.0 mg. (B) Multiple repeating CO2 bursts used to simulate patterns of superimposition (without additional CO2). A large singlet burst (red arrow in A) was repeated at frequencies (f) of 14, 20, 33 and 50 min–1.
