Fig 1.
Plastic effects of 533 nm ambient light exposure on firefly flash morphology.
(A) Example of change in intensity of flashes emitted by A. ficta male under different illumination conditions (indicated above each section), recorded in units of average counts per 100 ms over 4 min. (B) Changes in signal intensity over 4 min of separate A. ficta male under the same illumination conditions (indicated above each section).
Fig 2.
Effects of exposure wavelength and intensity on firefly flash morphology.
Change in average (± 1 SE) flash intensity (A) and frequency (B) of light signals emitted by A. ficta under illumination by eight wavelengths and two intensities of ambient light (N = 6). Base values for average flash intensity (5420 counts) and flash frequency (43.167 peaks/min) obtained from 1 min dark recordings have been subtracted out.
