Geographical Variation in the Advertisement Calls of <italic>Leptobrachella ventripunctata</italic> (Anura: Megophryidae) in Southwestern China

<p indent="0mm">In anurans, advertisement calls (ACs) are an essential form of intraspecific communication. This study evaluates geographical variation in the ACs of <italic>Leptobrachella ventripunctata</italic> in the Guizhou Plateau, southwestern China, and explores correlations between call characteristics, body size, and environmental factors. ACs are simple calls of <italic>L</italic>. <italic>ventripunctata</italic>, and apparent differences were observed in the ACs among different geographical populations of <italic>L</italic>. <italic>ventripunctata</italic>. The Call duration (CD) revealed a significant positive correlation with altitude and a significant negative correlation with temperature and humidity. Moreover, the Dominant frequency (DF) exhibited a significant negative correlation with altitude and the habitat closure degree and a significant positive correlation with temperature. These variations in ACs between different geographical populations of <italic>L</italic>. <italic>ventripunctata</italic> may critically impact the adaptive evolution of species, and the calls may also be relevant for environmental selection.
