Abstract

Hylarana nicobariensis (Stoliczka, 1870) is a very common frog, which has a wide distribution, covering the southern part of Thailand, Peninsular Malaysia, Sumatra, Borneo, Java, Bali and Palawan in the Philippines. The presence of this frog is very easy to be recognized by listening its shrill call that is sounded loudly all day. Detailed descriptions of H. nicobariensis’s calls from Ulu Gombak in Peninsular Malaysia and Danum Valley in Sarawak have been published by Jehle and Arak (1998), which are some call characters of the frog from the two locations are significantly different. To determine the call characters that can distinguish among populations of this frog, advertisement calls of five different populations (Batukaru, Curup, Limau Manis, Curug Nangka and Lake Ecology Park) were analyzed. The characters of the call waves on the five populations are different in the structure of sub-pulses, dominant frequency and lower frequency. Among the five populations, the population from Lake Ecology Park is the most different in the terms of the dominant frequency (3996.95 ± 124.74 Hz) and lower frequency (1692.51 ± 80.77 Hz), of this population both these characters occupy the highest level compared to four other populations; however individuals from Curup occupy the lowest level on dominant frequency (2919.67 ± 67.76 Hz) and lower frequency (832.96 ± 32.42 Hz).Key words: Ranidae, Hylarana nicobariensis, bioacoustics

Abstract

Advertisement calls of Microhyla palmipes and Oreophryne monticola have never been described before; howevercharacteristics of M. orientalis’s calls has been described just to support new species publication. The advertisement calls oftwo individual males of M. orientalis and M. palmipes which originated from Wongaya Gede, Bali were recorded in July2010 at air temperatures of 26.0°C. Three individuals males of O. monticola were recorded in Eka Karya Botanical Garden,Bali at air temperature of 25.0°C. Call components were obtained from 65 calls of M. orientalis, consisting of 95 pulses; 10calls of M. palmipes, consisting of 113 pulses; 3 calls of O. monticola, consisting of 127 pulses, which were then analyzed toobtain the characteristics of sound waves by using software of Adobe Audition 3.0. Sound waves of M. orientalis mainlyconsists of two dominant frequencies raging from 1873-2062 Hz and 3375-3562 Hz; however sound waves of M. palmipesand O. monticola mainly consist of only one dominant frequency that ranges of the frequency is the same, i.e. 3000-3937Hz. Although M. palmipes and O. monticola have the same range on dominant frequency, but the two species have significantlydifferent on number of period per pulse, pulse duration, pulse interval, pulse period, call duration and call interval.Key words: frog call, Microhylidae, Bali Island

Abstract

ABSTRACTCall characteristics of Limnonectes modestus (Boulenger, 1882) which is endemic to Sulawesi have never been described before.  The advertisement calls of two individual males collected from Nantu Wildlife Sanctuary, Gorontalo, northern Sulawesi were recorded in December 6, 2014 at air temperatures of 26°C.  Adobe Audition 3.0 software was used to visualize sound waves.  Advertisement call of L. modestus is very simple, which only has one type of call containing 1-6 pulses.  Pulse duration, pulse rate and call rate of the two individual males are very diverse, ranged between 21-56 milli seconds, 2.58 to 7.87 pulses/second and 0.09-1.16 call/second; but the frequency variation of call is very low, the lower frequency range between 515.6 to 593.0 Hertz (CV=3.1%), whereas the upper frequency range between 2179.0 to 2859.0 Hertz (CV=5.4%); the band width of the frequency range between 1616.5 to 2320.0 Hertz (CV=7.1%). Key words: vocalization, Limnonectes modestus, Nantu Wildlife Sanctuary, North Sulawesi
