The python of Indonesian Sundaland has been traded for its distinct skin colour and patterns. The need for rapid method in cross-species amplification for Indonesian Sundaland python is useful to contribute in management of sustainability harvesting system. In this research, we screened 10 microsatellite primers which are previously used for Australian, New Guinean, Chinese and Burmese pythons and 7 potentially amplifiable primers for African and Asian reptiles. Python breitensteini showed a greater number of alleles (2-8 alleles) than Python bivittatus (1-3 alleles) and Python brongersmai (1-2 alleles). The observed and expected heterozygosity for all species were ranged from 0 to 1.00 and 0 to 0.79, respectively. According to the high cross-species amplification rates, 15 out of 17 primers were useful in assessing the genetic diversity and conservation genetic of Indonesian Sundaland python. Among the 15 primers, MS3 generated the highest number of allele for P. breitensteini (8 alleles), P. bivittatus (3 alleles), and P. brongersmai (2 alleles). We proposed MS3 locus as a suitable marker for Indonesian Sundaland python.Keywords: microsatellite, Python, Sundaland.

Human population growth has rapidly conversed the natural environment into agricultural and plantation area in Indonesia. This phenomenon resulted a reduction and fragmentation habitats, and led to the loss of biodiversity. By exploring Wonosobo, we were able to analyse the herpetofauna composition on three different habitat, including river, salak plantation [Salacca zalacca (Gaert.) Voss], and paddy fields. We identified 17 species (60,7%) from river, 15 species (53,6%) from paddy field, and 13 species (46,4%) from salak plantation. Shannon-wiener index diversity (H’) categorized herpetofauna diversity in all three habitats as medium. Meanwhile, the evenness index (E) showed that herpetofauna community in river classified as unstabile (E=0.7302). River was predicted be functioned as transit area for herpetofauna to hunt. There were no herpetofauna species predominating all three habitats, and this indicating that the ecosystem balance was well preserved. This study revealed that agriculture and plantation area affected the herpetofauna composition, yet it still able to maintain the diversity well. In addition, the water bodies, including river and irrigation in agriculture and plantation area, should be maintained its quality as it plays an important part in herpetofauna conservation. Keywords: fragmentation, herpetofauna composition, habitat

Indonesia is known as one of the highest supplier on animal illegal trading, especially reptile. The objectives of this study are to reveal the preparation proccess of reptiles in the wholesaler and the flow of illegal trade through deep interview and observation in Kebumen Regency, Central Java, Indonesia. The results showed that wholesaler did some specific processes towards reptile. As much as 289 reptiles were observed to be traded in various conditions. Dry season affect the amount of animal sold. Chinese Ratsnake (Ptyas korros) and Reticulated Python (Malayopython reticulatis) became the most traded commodity within reptile trading, and is reported to be exported to other countries. Trafficking of adult reptiles could threaten their wild population, yet the level of exploration and monitoring toward reptile’s wild population are still low.Keywords: Kebumen, reptile, trade, population, wholesaler

The population of herpetofauna (Class: Reptilia, Amphibia) is continuously declining throughout the world. Moreover, habitat changes such deforestation drive rapidly to declining process. Human communities play an important role in conserving the herpetofauna by maintaining and improving the harmonious relationship between human and environment. Therefore, these association will strongly support the conservation of herpetofauna and their habitats. This study is aimed to survey the herpetofauna communities, explore the local people perspective on herpetofauna, and the relationship between human and herpetofauna. We found 12 species observed in this survey that included to 3 order of herpetofauna: anura, squamata and testudines. Local people recognized herpetofauna species around them well and do not harm them because of their roles, such as part of nature (39%), bioindicator (33%), myth (17%), and economic value (11%). We also revealed the local knowledge on herpetofauna, as 14 local names and their roles. Despite Kuala Tungkal is a strategic area for the national port development that probably impacts herpetofauna microhabitat, it needs serious attention on herpetofaunal issues.

Bandar Bakau is a mangrove conservation area with approximately 20 ha that preserves many kinds of fauna, including Mangrove Pit Viper Cryptelytrops purpureomaculatus. However, this species and its habitat are still poorly studied in Indonesia, particularly Sumatera island, despite it has a wide distribution in Southeast Asian countries. The main purpose of this study is to evaluate the microhabitat of Mangrove Pit Viper C. purpureomaculatus that found at a restricted mangrove area in Dumai, Riau Province. Visual Encounter Survey (VES) and deep interview methods were used in this study. The survey found six individuals of C. purpureomaculatus that mostly basking on the Avicennia marina and artificial building. Although Bandar Bakau is a tourism object, but no snakebite cases were found.

Lake Ranu Pani has been experiencing environmental damage due to human activities, while Lake Ranu Regulo is still in good condition. This difference in environmental conditions allows for differences in the genetic diversity of animals in the area. The aim of this research is to know the genetic diversity of Ischnura aurora needle dragonfly based on morphometric analysis in both locations. A total of 8 morphometric characters (in mm) were measured using a digital caliper. Data were analyzed using T test, biplot and cluster. T test results showed that male I. aurora in both sites was not significantly different, nor did females, but there were differences between male and female aurora at each location ie body color, wing span (WS) and length of hindwing (LH). Biplot analysis showed the uniformity of sample distribution for each character. The dendogram results described most of the samples were clustered into a single group. The result data showed that genetic diversity of I.aurora in Ranu Pani and Ranu Regulo lakes is still low. Keywords: Damselfly, Morphometric, Ranu Pani, Ranu Kumbolo
