Abstract

The goal of this project was to examine intraindividual variability in the calling song of the male cricket, Gryllus pennsylvanicus. We evaluated syllable period and chirp period lengths under both constant and changing temperature conditions. Significant variability in chirp and syllable period length was found under constant conditions, suggesting males are subject to internal variability without any effects from the environment. Significant variability was also seen in chirp and syllable period length for crickets under changing temperature condtions. There was a two to five minute delay in response to the temperature change.
