Variation in signal complexity is common among different species. Understanding why some species have evolved extensive call can offer insight into the evolution of complex signals. In this study, we investigated functions types a treefrog using network analysis, male playback experiments, and correlation analysis between properties body size. Our results show that treefrogs produce three kinds notes be combined to single-note as well composite calls. We also identified an intermediate note type advertisement suppress call, indicating calls may from The revealed functional distinction Additionally, our study dominant frequencies size calling males. Male frogs combine sequences form graded calls, which perform communication functions. indicate needs drive complexity, provides new evidence social hypothesis deeper insights function animal acoustic communication.

The Gaoligong Mountain Range in Yunnan Province, China, is characterized by its large variation elevation and topography, together with wide latitudinal range, resulting extremely high levels of biodiversity. Studies show that the amphibian diversity largely underestimated, especially south. During herpetological surveys 2023 2024, three specimens Leptobrachella were collected from mountain at Tongbiguan Provincial Nature Reserve. Subsequent morphological comparisons a phylogenetic reconstruction revealed these belonged to previously unknown morphologically distinct lineage , which we formally describe. Our discovery brings number species genus 108, 44 occur seven on Range. This result confirms underestimated Range, Reserve, where multiple sympatric congeneric occur, including four five putative new Xenophrys Polypedates . These findings also highlight need for future research investigate mechanisms syntopic coexistence.

Phylogenetic analysis 16S mtDNA fragments revealed that is closely related to L.damingshanensis. Uncorrected p-distances between all homologous DNA sequences available for gene Leptobrachella are greater than 7.1%. Morphologically, nov. differs its congeners in several ways, including a medium body size (SVL 26.0-26.7 mm males, 30.6-34.8 females), lack toe webbing lateral fringes, shagreened granular dorsal surface, pale brown dorsum with darker markings, iris bicolored, upper half copper fading silver lower half, presence small irregular black spots tangerine tubercles flanks.
