Abstract

Morphometric study has showed that Asian Striped Tree Frog popula-tions from Sulawesi can be separated from populations discovered in other islands (Sumatra, Java and Kalimantan) and become accepted as a new species, namely Polypedates iskandari (Riyanto et.al., 2011). However, the results on analysis of vocalizations sequences have indicated that, P. iskandari and P. leucomystax from Java population use similar acoustic bandwidth frequencies in the major call. The different between the two species can only be found in minor calls; P. iskandari has a higher dominant frequency range than P. leucomystax. This study shows that minor calls are not important in communication among males. Therefore, based on acoustic analysis, there is no sufficient evidence to classify the Sulawesi population of P. leucomystax as a new species.Keywords: vocalization, Polypedates leucomystax, P. iskandari, Sulawesi, Java

Abstract

Frogs communities of degraded areas in Curug Nangka area, West Java. A Total of thirteenfrog species were found in degraded land areas of Curug Nangka, on the foot hills of MountSalak at elevation of 640 m - 730 m above sea level (asl). In the fast-flowing river habitat, threefrog species dominated this habitat, they were Huia masonii, Hylarana chalconota andOdorrana hosii; whereas in fast-flowing ditch habitat, Phrynoidis aspera and H. chalconotawere the dominant species, and for the pine plantation, H. chalconota and H. nicobariensisdominated this habitat. On the river transect, the presence of individuals H. masonii wasinfluenced by the dynamics of air temperature and water temperature. In the open ditchtransects, the presence of individual P. aspera was influenced by water temperature. Therewas a stronger positive association between the presence of individuals H. masonii andindividuals of O. hosii than between individual O. hosii and H. chalconota on the rivertransect. Among individuals of H. masonii and individuals of H. chalconota there was apositive association; however in the open ditch transects, there was no association betweenthe presence P. aspera and H. chalconota. The presence of H. chalconota and H. nicobariensison the pine plantation transect had strong positive association.Keywords: frog community, degraded area.

Abstract

Vocalizations of Microhyla achatina have never been described before. The advertisement calls of six individual malesof M. achatina which originated from the foot hills of Mount Salak, West Java were recorded in September 2011 atair temperatures of 21.0°C-23.4°C. Call components were obtained from 95 calls, consisting of 855 pulses, whichwere then analyzed to obtain the characteristics of sound waves by using software of Adobe Audition 3.0 andSAP2011. Sound waves of M. achatina mainly consists of impulses whose sound spectrum ranges from 1327.5-2789.1 Hz, while the band width of the spectrum is 1461.6 Hz. Results of the analysis showed that the frequency ofthe three pulse-forming elements (dominant frequency, maximum frequency and minimum frequency) was markedlymodulated; frequency modulation was clearly visible in the minimum frequency, which was modulared by 1500 to2700 Hz modulation. The modulation of the dominant frequency and the maximum frequency was not too broad,i.e. between 3000-3500 Hz. Results of linear regression analysis of the dominant frequency versus minimum frequencyand dominant frequency versus maximum frequency showed a strong correlation between the dominant frequencyversus minimum frequency, but a weak correlation between the dominant frequency versus the maximumfrequency.Keywords: vocalization, Microhyla achatina, West Java.
