Habitat loss and fragmentation are among the largest threats to herpetofauna diversity in tropical rain forest areas, including the rain forest in Kerinci Seblat National Park (KSNP). To measure the rate of negative impact to the herpetofauna population,fifteen survey sites with several degree of habitat disturbance were selected. Based on cluster analysis,15 survey sites were grouped into five distinct clusters, included low elevation forest group, high elevation group, swamp group, disturbed forest group and cultivated land group. Calculation of linier regression for four major (low elevation forest group, high elevation group, disturbed forest group and cultivated land group groups) showed that the rate of locally biodiversity losses were high (R2 > 0.7).

Selama survai herpetofauna di Taman Nasional Ujung Kulon yang dilakukan pada bulan Juli sampai September 1990 dijumpai 14 jenis amfibia; yang terdiri dari satu jenis dari suku Megophryidae, tiga jenis dari suku Bufonidae, tiga jenis dari suku Microhylidae, lima jenis dari suku Ranidae dan dua jenis dari suku Rhacophoridae (Kumiati el al.. 2001). Survai herpetofauna Iain terutama untuk kelompok amfibia pernah dilakukan Liem (1973) di Taman Nasional Gede-Pangrango. Survai tersebut berlangsung pada tahun 1961-1962, dan lebih intensif lagi dilakukan pada bulan Agustus 1963, Maret dan Mei 1964. Dari survai ini Liem (1973) mendapatkan 19 jenis amfibia; yang terdiri dari dua jenis dari suku Megophryidae, empat jenis dari suku Bufonidae, dua jenis dari suku Microhylidae, tujuh jenis dari suku Ranidae dan empat jenis dari suku Rhacophoridae. Untuk mendapatkan gambaran umum keanakaragaman herpetofauna dari tiga taman nasional yang terdapat di Jawa Barat, maka dilakukan survai herpetofauna di Taman Nasional Gunung Halimun; yang berlangsung intensif sejak bulan Oktober 2001. Dua puluh dua jenis amfibia didapatkan selama survai tersebut; yang terdiri dari dua jenis dari suku Megophryidae, empat jenis dari suku Bufonidae, satu jenis dari suku Microhylidae, sepuluh jenis dari suku Ranidae dan lima jenis dari suku Rhacophoridae. Indeks kesamaan Simpson digunakan untuk membandingkan keanekaragaman jenis antara dua taman nasional. Hasil indeks koefisien Simpson antara Taman Nasional Ujung Kulon dan Taman Nasional Gunung Halimun adalah 0,786; antara Taman Nasional Ujung Kulon dan Taman Nasional Gede-Pangrango adalah 0,786; dan antara Taman Nasional Gunung Halimun dan Taman Nasional Gede- Pangrango adalah 0,842. Berdasarkan kepada nilai indeks tersebut, kesamaan keanekaragaman amfibia di Taman Nasional Gunung Halimun dan Taman Nasional Gede-Pangrango sangat tinggi.

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

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%).

Giant River Toad {Phrynoidis aspera (Gravenhorst, 1829)} is a largest generalist toad that is able to adapt to a variety of habitats and elevations. The complete calls of Giant River Toad had not been published before. To know all of sound characters of the toad, a total of five individuals males P. aspera vocalization were recorded on 30 October 2010 (1 individual; air temperature: 23.1°C; water temperature: 18.1°C) by using an Audio Technica AT875R microphone, the sound was recorded on a Fostex FR 2LE in WAV format; and on 22-24 September 2011 (4 individuals; air temperature 21.0°C-23.4°C; water temperature 21.6°C-22.0°C) in Curug Nangka, Mount Salak foot hill,West Java by using PCM-M10 Sony Recorder. The toad has four types of call: (1) Call type 1, consists of impulses without harmonic and average band width is 317.44 Hertz and average of amplitude is 40.43; (2) Call type 2, consists of pure tone with many sub-harmonics, average range frequency is 1420.28 Hertz and average of amplitude is 42.67; (3) Call type 3, consists of impulses and pure tone with two weak harmonics and average band width is 373.81 Hertz and average of amplitude is 48.19; (4) Call type 4, consists of impulses without harmonic and average band width is 792.62 Hertz and average of amplitude is 51.01. Based on the number of calls that were recorded of five individuals from the Mount Salak foot hill, call type 4 is its major call (common advertisement call), but the three others call types are minor calls.

ABSTRACTOn CoP 18 which will be held in Sri Lanka in 2019, house gecko was proposed to be uplisted up listed from the non-appendix status of CITES to be included the list of CITES appendix II on the reasons that the hunting of the reptile was very large and uncontrolled. In order to anticipate the up listing of house gecko status, LIPI as a Scientific Authority in Indonesia recommended quota for house gecko in 2019 to be 1,800,000 individuals. To see that such a quota does not have a negative impact on the population of house gecko in the wild, a survey was conducted by using the close questioner system method by visiting housing in a village; where in this survey the villages were located at the foot hill of Gunung Karang, Pandeglang Regency, Banten Province. The survey was conducted on March 18 to April 1, 2019. The total number of villages visited was 8 villages which were divided into three sub-districts. The total area surveyed in 8 villages was around 94.5 hectares. The total number of houses visited was 740 houses; the total number of houses that contained the house gecko was 211 houses. The total number of house gecko by interviewed was 260 individuals, while the total number of house geckos by observed was 88 individuals. The survey results obtained an average population density of house gecko by interviewing eight villages was 3.66 individuals/hectares, while the observation results were 1.15 individuals/hectares. The approach to the average population density of houses gecko by interviewing with the results of 3.66 individuals/hectares was assumed to be the density that was close to the logical number. Extrapolating the density of house geckos in Pandeglang Regency which covers an area of 229,071 hectares excluded paddy field area was considered to be inhabited by house gecko, so the extrapolation of the number of house geckos in Pandeglang Regency is around 838,399.86 individuals. Keywords: Gekko gecko, house gecko, Java, population
