<p>Vocalization plays an important role in the
communication of anurans. In this study, the advertisement calls of male <i>Fejervarya multistriata</i> obtained in
Lishui, Zhejiang, China during the breeding season were recorded. Their note
number (NN), note duration (ND), note interval (NI), call duration (CD), pitch
(PIT), call intensity (CIT) and dominant frequency (DF) were analyzed. The
calls of <i>F. multistriata</i> are composed
of one to 38 notes, and calls composed of fewer than ten notes have the highest
frequency. Male frogs produced calls ranging from 1201 Hz to 3357 Hz with two DFs
(1412.49 Hz and 2953.89 Hz). By comparing the differences among individual
calls, it was found that the within-individual coefficients of variation (CV<sub>W</sub>)
and among-individual coefficients of variation (CV<sub>A</sub>) for NN, NI, CD,
PIT and DF were more than 10%, whereas that of CIT was less than 5%. The CV<sub>A</sub>/CV<sub>W</sub>
ratios showed that ND is important for sexual selection, whereas NN, NI CD, PIT,
CIT, and DF are important for individual recognition. Phylogenetic generalized
least squares analysis showed that phylogenetic signals affect DF<i> </i>vs<i>. </i>snout–vent length (SVL) and CD of anurans
in China, and accounting for phylogenetic signals, DF was negatively correlated
with SVL. DF was found to be higher in anurans that breed in flowing water than
in those that breed in stagnant water, after eliminating the effects of phylogeny
and SVL. Therefore, we concluded that phylogenetic effects, SVL, and the water type of breeding habitats have a combined
impact on the advertisement calls in anurans.</p>
