Geographical divergence in acoustic signals is often affected by multiple selective pressures. Environmental factors are expected to shape adjusting for greater propagation efficiency. Nevertheless, such habitat-driven hypotheses have not been well-examined with multi-signal and multi-habitat types included simultaneously. In this study, we evaluated call similarity of the spot-legged treefrog (Polypedates megacephalus), characterized types, from 11 geographic populations across Hainan Island. We also examined (i.e. body mass, temperature, altitude, vegetation) among different acoustical clusters, tested whether variation length frequency habitats was accordance prediction derived adaptation hypothesis. showed that P. megacephalus Island 3 clusters: northeastern flatlands, southwest mountains, hills around mountains. environmental altitude varied these acoustically distinct areas. Moreover, duration supported hypothesis they should optimal transmission their own habitats. Thus, our results reveal roles ecological selection geographical anuran signals.

Male frogs emit stereotypical advertisement calls to attract mates and deter conspecific rivals. The evolution of these is thought be linked anatomical constraints the acoustic characteristics their surroundings. adaptation hypothesis (AAH) posits that species evolve maximize propagation distance reduce signal degradation in environment where they are emitted. We applied phylogenetic comparative analyses study association body size, vegetation density, type aquatic ecosystem, calling site on traits Cophomantini, a large radiation Neotropical treefrogs (Hylidae). obtained analyzed acoustic, habitat data from total 112 (58% Cophomantini), using most inclusive available phylogeny. found significant negative correlation between peak frequency, site, but contrary predictions AAH, we did not find support for associations among call environmental characteristics. Although spectral allometry explained by an constraint, it could also maintained female choice. recommend future studies strive incorporate factors such as mate preferences, eavesdropping predators or parasites, genetic drift.

Despite a relatively broad distribution in Africa, the Spotted Rubber Frog, Phrynomantis affinis, is extremely rarely encountered. Only 18 specimens from 12 localities have been collected with few additional observations recorded. Virtually nothing of species' natural history known. We report or summarise new and range extensions P. affinis Namibia Zambia describe call for first time. also compare its to that sister species, bifasciatus, describing this time noting considerable extension. The calls show several key differences, generally having lower dominant frequency, pulse repetition rate, number pulses than bifasciatus. Namibian Zambian marked differences. These descriptions add valuable information both species will considerably improve field detection enigmatic affinis.
