“…The acoustic data displayed in the spectrogram are helpful for identifying the species of anura being studied. Call sounds play a very important role in mate selection by female individuals and as a medium for males in carrying out their reproductive activities (Xiong et al, 2015); In addition, the call sound is also considered one of the key characters responsible for reproductive isolation and speciation processes in the toad group (Cocroft & Ryan, 1995;HC Gerhardt, 1991;Howard & Young, 1998;Leary, 2001;Wei et al, 2012). Pulse and frequency variations can be seen from Appendix (1).…”

Indonesia is a country with very high biodiversity and is known as Mega Biodiversity. In Indonesia found about 450 species of Anura representing about 11% of all species in the world, and 28 species ofwhich 28 live in West Java. Anura animals have a pattern of calling behavior that is essential for mating: males produce call-up behavior that attracts females and, in some species, represents the extent of their territory. Research on frogs and toads is considered necessary considering the absence of more detailed data on the bioacoustics of these frogs, especially in the West Java area, so that variations and patterns of anura sounds are known in the Telaga Warna Nature Reserve and Nature Park (CA-TWA) area and can make scientific contributions in information on variations and sound patterns owned by anura animals in terms of anura conservation in Indonesia. This research was conducted from month March-December 2018, located in Telaga Warna Nature Reserve and Nature Park, Bogor, West Java. Call the recording every 6:00 p.m. to 11:00 p.m. each night during the sampling period. The number of anura species in the villa and swamp areas is more abundant than the lake area, and the presence of Pearl maroon frogs (nyctixalus margaritifer) found in the villa and lake areas, while the Bufo melanotictus type that likes to live in the lake area. It can be seen that the villa and swamp areas are still maintained vegetation by looking at the medium density of the canopy. Steeper slope conditions help the flow of nutrients from the soil due to the erosion process and settle in flat to gentle areas. The density of the canopy in the area helps maintain the surface temperature of the land with a stable land surface temperature ranging from 15 – 21 0C.

The characteristics of male anurans' calls play an important role in mating success during the breeding season. In this study, we analyzed intra-and inter-individual variability of the advertisement calls of the pale-shouldered horned toad (Xenophrys boettgeri) in the field during its breeding season in Lishui, Zhejiang Province, China. The results showed that some acoustic parameters were significantly correlated with morphological features and air temperature. Most acoustic parameters including note numbers, call duration, and dominant frequency were static, whereas the call interval was intermediate. The CV b /CV w ratio was greater than 1.0 for all acoustic parameters analyzed, with between-individual variation being higher than within-individual variation. Furthermore, the acoustic parameter results of principle component analysis and discriminant function analysis indicated that note numbers and call interval are potentially useful for individual discrimination of X. boettgeri.

Vocalization plays an important role in the communication of anurans. In this study, the advertisement calls of male Fejervarya multistriata 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 F. multistriata 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 (CVW) and among-individual coefficients of variation (CVA) for NN, NI, CD, PIT and DF were more than 10%, whereas that of CIT was less than 5%. The CVA/CVW ratios indicate 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 vs. 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 conclude that phylogenetic effects, SVL, and the water type of breeding habitats have a combined impact on the advertisement calls in anurans.
