Abstract

Sound production is a widespread phenomenon among animals. Effective sound use for mate or species recognition requires some acoustic differentiation at an individual or species level. Several species of caudate amphibians produce underwater sounds, but information about intra- and interspecific variation in their acoustic production is missing. We examined individual, sex, and species variation in underwater sound production in adults of two sympatric newt taxa, and . Individual newts produced simple low- (peak frequency = 7-8 kHz) and mid-high frequency (14-17 kHz) clicks, which greatly overlap between sexes and species. Individual differences explained about 40-50% of total variation in sound parameters. These results provide foundations for further studies on the mechanisms and eco-evolutionary consequences of underwater acoustics in newts.
