The reserve is surrounded by human habituation which provide opportunity to study the impact of forest lost on biodversity. In addition, data on Nantu mostly focused on big mammals, as there is no previous herpetofauna survey at the area. Sampling of amphibian and reptile was conducted in June 2013 and in May June 2014 using-Visual Encounter Survey method, glue traps and transect sampling in seven different sites at the eastern part of Nantu. We categorized four habitat types based on human disturbances: high disturbed habitat (HDH), moderate disturbed habitat (MDH), low disturbed habitat (LDH) and pristine habitat (PH). A total of 680 individual amphibians (4 families; 17 species) and 119 individual reptiles (9 families; 29 species) were recorded. Species richness and species composition for amphibians and reptiles differs according to the level of human disturbances. Low level disturbances habitat demonstrated the highest diversity of amphibians and reptiles, whereas as expected, high distubed habitat showed the lowest diversity. Anthropogenic pressures in forest will decrease species richness of amphibian and reptiles. Although most amphibian and reptiles will be able to persist in low disturbances habitat, forest-dependent species will be lost when pristine forests are disturbed.

Amphibians have an important role in eco system and produce many bioactive peptides. However, the genetic information of amphibians from Indonesia is very limited, especially Duttaphrynus melanostictus and Phrynoidis asper. The aims of this study are to determine the nucleotide sequence of cytochrome oxidase I (COI) from D. melanos tictus and P. asper, to analyze their genetic diversity and their phylogenetic relationship. A total 668 base pairs of COI gene fragment were successfully amplified and their nucleotide sequence deter mined. P. asper (5 haplotypes) samples group have high haplotype diversity compared to D. mela nostictus (1 haplotype). The results of Basic Local Alignment Search Tools (BLAST) to the NCBI and BOLD database, showed 99 % 100 % identity to sequence of D. melanostictus. For the sequence of P. asper showed 99.23 % identity to sequence P. asper in BOLD database. There was no sequence of COI gene of P. asper in NCBI database. Genetic relationship among species in family Bufonidae, indicated that D. melanostictus has closer relation to P. asper than to another species, inspite of their pharapyletic characteristic. For intern species relationship of D. melanostictus, the data showed that D. melanostictus from Bogor have closer relationship to D. melanostictus from India than D. mela nostictus from China.

Its current stronghold includes the mountain range from Mount Gede-Pangrango National Park to Cibodas Botanical Garden in forested habitats at altitudes between 1400 meters above sea level (Ciwalen) to 1800 masl (Swamp svelte) with highest abundance in Cibeureum (1700 masl) (Kusrini et al., 2007; Lubis, 2008). It is also found in Mount Merapi National Park and in East Java around the Ijen plateau. The species is listed as "Least Concern" by the IUCN Red List 2009 (Iskandar et al., 2009) and not listed as a protected species by the Government Regulation 7 of 1999. The population density is believed to be stable (Kusrini et al., 2007) although habitat loss and disturbance are becoming increasing threats to its existence. Very little is known about the species' behavioural ecology and population biology. Research about the food and feeding behaviour of R. margaritifer is important to understand its conservation needs as well as to develop effective conservation interventions. Like many other frog species the Javan tree frog feed on a range of insects, and it is possible that the species is an important predator of several species of insects that are considered

This study aimed to analyze the perception of visitors about estuarine crocodile in captivity and facilities in two captive breeding sites. We conducted field observation and structured interview to 120 respondents in two local zoos: the Indonesia Jaya Crocodile Park (TBIJ or crocodile park) in Bekasi and Ragunan Zoo (TMR or the zoo) in Jakarta. All visitors have low knowledge about estuarine crocodile, which they obtained mostly from mass media. Although most visitors know that estuarine crocodies are protected however in pratice their don’t have enough empathy to captive crocodiles. Visitors to both areas are local who lives near the vicinity of the park or zoo. Crocodile park visitors mostly came from Bekasi with an average number of visits 1 time and 1-hour length of visit. The reason for their visit were the closeness of the location and to learn crocodiles. The zoo visitors mostly came from Jakarta with an average number of visits more than 3 times and 6 hours length of visits. Respondents visited the zoo because of low cost and recreation. Visitors of the zoo provided positive review for several aspects in the zoo, while visitors in crocodile park gave positive review only on physical condition of crocodiles.

It has been found in several areas in the mountainous part of western Java, one of which is in the Chevron Geothermal Indonesia (CGI) concession area within Mount Halimun-Salak National Park. An ecological study of this species and its habitat was conducted in CGI from April to September 2008. The biological and ecological aspects of this tree frog such as morphology, habitat characteristics, breeding behaviour, and larval development are presented in this paper. This study found that the fertilised eggs hatch as free-swimming tadpoles. In addition, the availability of artificial habitat in the form of concrete ponds helps sustain the population throughout the year. We also report parental care in this species.

Underlying this challenge is the biodiversity paradox: biological diversity predominantly concentrates in the tropics, while human, institutional, and financial resources are primarily located at higher latitudes both north and south. Addressing the biodiversity paradox requires the expansion and mobilization of human, institutional and financial resources around the world. We outline a model championed by the IUCN Species Survival Commission (SSC) that builds on the Species Conservation Cycle (Assess-Plan-Act-Network-Communicate) and recognizes that most conservation action occurs at the national or local level. Various strategies are applied to this end by the partners of Reverse the Red, a global movement that ignites strategic cooperation and science-based action to ensure the survival of wild species and ecosystems.

Excessive exploitation may threaten the stability of the population in the wild. The research of morphological characteristics of batik python conducted in North Sumatra was aimed to identify the characteristics of harvested P. reticulatus that has been processed at the slaughterhouses to predict changes in population structure in the wild. The data observed and analyzed were number of harvest, sex, sex ratio, morphometry, age class, reproductive maturity and feed type. Sex ratio from 272 specimens analysed from the slaughterhouse was 1: 0.86, or 53.68% males and 46.32% females, age class juvenileOf 29.04% with sex ratio of 1: 0.42 and adult of 70.96% with sex ratio of 1: 0.93. Mean snout vent length (SVL) of harvested Reticulated python was 272.67 cm (SD = 37.76). There was a significant difference in SVL between males (mean = 267, SD = 37.04) and females (mean = 278, SD = 37.91) at the same age class (p = 0.019). Results of this study support the conclusion of previous studies that commercial skin trade does not terminate the population of reticulated python in Indonesia. However, the tendency of smaller body size of harvesting python compared to previous studies indicates the possibility of excessive harvesting.

Here we report the fourth sighting of Ichthyophis hypocyaneus, in Gunung Halimun-Salak National Park. The individual was found in a flooded grassland and we described habitat and vegetation in the vicinity of the site. We hypothesized that it was either breeding or feeding as it was active at the site, and flooding had provided both breeding habitat and numerous preys. Although being a single sighting we would like to draw attention to the fact that no ecological preferences have been described for the species, and that such studies are urgently needed.

The study aimed to reveal the diversity of fig trees in a tropical urban residential area of Sentul City, Bogor, West Java, as a part of a bigger study on the wildlife-fig relationship. A purposively selected sample (270 ha of housing, boulevard) and allFicuswere censused. Data on species diversity, height, diameter, and fruiting stage were taken. There were 389Ficustrees, belonging to 10 species, namelyF. benjamina, F. binnendykii, F. caulocarpa, F. elastica, F. kurzii, F. lyrata, F. maclellandii, F. macrocarpa, F. septica,andF. variegata, of which two species (F. lyrataandF. maclellandii) were non-native species.Ficuswere planted as a border, roadsides, shading trees, or ornament. Based on the number of individuals, the most common species wasF. benjamina(63.75%), followed byF. kurzii(14.4%) andF. lyrata(9.5%). As theF. benjaminacan grow big, only about half (56.4...

Captive breeding of this turtle is important to continue their sustainable utilization. PT Ekanindya Karsa was one of the pioneers in captive breeding of this species since 2008. Until now, reference related to management and maintenance techniques of softshell turtle in captivity are few. This research aims to analyse feeding preferences in juveniles. The results will assist wildlife conservation efforts and improve captive breeding effort for the future. Research was carried out at PT. Ekanindya Karsa from July to October 2012. Fifteen juveniles were given food for 9 weeks comprises of tuna, shrimp, spinach and sweet potatoes with cafeteria methods. Based on the number of food intake and cost efficiency, prefereed food was sweet potato and tuna. Feeding activities were visible in the morning (7.00 – 10.00 am) and evening (7.00 – 10.00 pm) with ad libi...

The total area is 7.959 ha, making Labanan Research Forest as the largest of the 33 research forest in Indonesia. Labanan Research Forest has high biodiversity due to its various kinds of biophysical characteristics. Nevertheless, the database of biodiversity in Labanan Research Forest has not been well documented yet. We did exploration to investigate potential of flora and fauna in Labanan Research Forest, consisting of vegetation, mammals, birds and herpetofauna. The exploration recorded 65 families and 183 genera of plants, 26 families and 53 genera of understorey plants, 41 species of mammals, 131 species of birds, and 71 species of herpetofauna. High biodiversity will be used as icon to promote Labanan Research Forest in order to increase researchers' interest to conduct further study at the site. Labanan

Padahal, tidak kurang dari 450 jenis amfibi diketahui terdapat di Indonesia dan hanya sedikit informasi detil mengenai biologi dan ekologi yang diketahui. Sementara itu survei yang dilakukan oleh para ahli, yang kebanyakan adalah peneliti dari luar Indonesia, kerapkali menemukan jenis-jenis baru yang belum dideskripsikan. Pengalaman selama beberapa tahun terakhir menunjukkan bahwa hasrat mahasiswa ataupun peneliti lokal di bidang penelitian biologi dan ekologi amfibi sebenarnya meningkat pesat. Sayangnya, hal ini terkendala oleh minimnya pengetahuan mengenai metoda penelitian terutama saat melakukan penelitian di alam. Sebenarnya informasi mengenai metoda survei dan penelitian amfibi dapat dilihat dari berbagai buku ataupun jurnal ilmiah yang kebanyakan menggunakan bahasa Inggris. Namun demikian, banyak informasi tersebut yang tidak dapat digali oleh mahasiswa dan peneliti lokal karena adanya kendala dalam bahasa. Buku ini berkembang dari modul yang dibuat penulis saat mengajar mahasiswa jurusan KSHE Fakultas Kehutanan IPB maupun mahasiswa/peneliti muda dari berbagai institusi dalam berbagai pelatihan. Merekalah yang mendorong agar penulis mengembangkan modul tersebut menjadi sebuah buku yang mengetengahkan berbagai cara melakukan survei dan penelitian amfibi dalam bahasa Indonesia. Kepada merekalah, para herpetologis Indonesia di masa datang, buku ini saya persembahkan.
