Fig. 4. Typical recording of a hyperoxic switch recording of Pogonomyrmex
californicus. One ant, mass 8.25 mg, at 40°C and 20 ml
min1 STP. The recording begins and ends with baselines. The
large dip in
CO2
that follows hyperoxia is plainly visible. The drop in
H2O coincides
with the drop in
CO2. Following
the introduction of nitrogen, a rapid rise in both
H2O and
CO2 are evident.
CO2 rapidly
declines to near baseline levels, but
H2O plateaus at
an intermediate level; see text.
