Abstract

Advertisement calls of Microhyla palmipes and Oreophryne monticola have never been described before; howevercharacteristics of M. orientalisâ??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

ABSTRACTKarawang District is the largest producer of frog meat in West Java. To find out how the frog harvesting impacts to the represent condition of population in the wild, on 16-27 May 2016 population survey was conducted on paddy field in East Karawang by implementing transect method with total length was 3000 meters. The results of this transect method showed that the population of juvenile was the highest in most areas of transects, followed by pre-adult population. The population of adult individuals was at the lowest and most adult male individuals were detected by the call that they make. Conditions of water supply in rice fields also determine the conditions of juvenile and pre-adult populations; newly planted rice fields with high water availability obtained the highest population per unit area compared to the condition of paddy fields with a little water availability; but exceptions to the plowed rice fields, despite the availability of a lot of water but disturbance from human activities was also high. Average density per unit area m2 for a little watery rice fields to dry with a total length of 1500 meters transect were as follows: (1) juvenil density was 0.33 individuals/m2, (2) pre-adult density was 0.04 individuals/m2, (3) adult density was 0.005 individuals/m2. Average density for much watery rice fields with a total length of 1200 meters transect were as follows: (1) juvenile density was 0.89 individuals/m2, (2) pre-adult density was 0.08 individuals/m2, (3) adult density was 0.01 individuals/m2.Key words: population density, Fejervarya cancrivora, paddy field, Karawang District

Abstract

ABSTRACTTroides helena helena (Linnaeus, 1758) can be found in Java and Bali. The larval and adult stages of this butterfly do not produce any sound, but the pupal stage produces sound in response to a touching stimulus. Sony PCM-M10 recorder and Pettersson M500 USB Ultrasound Microphone were used to record the sound. Adobe Audition 3.0 was used to visualize the oscillogram and audiospectrogram of the sound. Beyond our expectations, the pupae produce ultra sound hisses which are composed of many impulses. A one-day-old pupa has a frequency range between 0.2-40 kHz; however of 2-days to 18-days-old has a frequency range between 0.2-150 kHz. The sound wave consist of two sound elements, i.e. the audible sound element (0.2-20 kHz) and inaudible sound element (>20-150 kHz) and the bandwidth is between 200 Hz to around 150 kHz, with the strongest spectrum energy at around 2.6 kHz, 4 kHz, 6 kHz, 9 kHz and 23 kHz and some strong spectrum energy is also visible at around 40 kHz.Key words: acoustic, behaviour, butterfly, pupa, Troides helena helena

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

Abstract

Hylarana celebensis (Peters, 1872) is an endemic frog to Sulawesi, the species being a member of family Ranidae.  The presence of the frog in its habitat is easily detected from its advertisement call; males usually call in a chorus, they call to each other in a large group. Bioacoustics of calls that a typical individual male of H. celebensis has not been described in detail, although it is very easy to find this species in freshwater swamps, permanent ponds, or slow-flowing waters in the lowland areas. The purpose of the bioacoustic analysis on H. celebensis?s calls that were recorded at Bahodopi area is to build a reference collection to be compared with H. celebensis?s bioacoustics to the other regions in Sulawesi. Because of the wide distribution of this frog in Sulawesi; population genetic structure of H. celebensis may also follow the population genetic structure of Ingerophrynus celebensis. Calls of H. celebensis have two types of calls, i.e. pure tone and pulse; however, pure tones have three variation, namely pure tone type 1, pure tone type 2 and pure tone type 3; however pulsed call has only one type. Keywords: Anura, Hylarana celebensis, bioacoustics, Sulawesi.

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.
