Abstract

Cyrtodactylus marmoratus is one of the first species described by Gray in 1831 on the island of Java that believed to have a variation of morphologic characters that not yet complete to revealed. This research aimed to develop any variation characters possessed by Cyrtodactylus marmoratus. The character morphology, morphometric, and meristic follow the statement of Hartmann (2016). Data were collected in August to November in the Lab. Herpetology MZB (Museum Zoologicum Bogoriense) LIPI (The Indonesian Institute of Sciences). Variation characters possessed  by Cyrtodactylus marmoratus, there are 4 Characters Morphology: Head Morph (HM), Patern Morph on the Body (PtrM), Post Cloacal Tubercles (PCT), and second post mental (PM2); a Morphometry Characters is snout-vent Length (SVL); and 12 characters Meristic are: Precloacal Pores (PP), Precloaco-femoral Pores (PFP), Enlarged Precloaco-femoral Scales (EPFS), Ventral Scales (VS), Paravertebral Tubercles (PVT), Dorsal Tubercles (DTR), Lamella Under Toe-IV (LT4), Lamella Under Toe-V (LT5), Lamella Under Finger-III (LF3), Lamella Finger-IV (LF4), Femoral Pores Left (FPL), Femoral Pores Right (FPR).

Abstract

Reticulated python (Malayopython reticulatus) is a widely distributed snake covering throughout Southeast Asia and almost all of Indonesia archipelago and divided into several subspecies based on morphological variation and its locality. Morphological variation data of M. reticulatus from Indonesia population has never been done thoroughly. This study aims to determine the morphological variations based on 21 meristic and 3 morphometric characters from several populations in Indonesia. The data was collected from the Museum Zoologicum Bogoriense (MZB) Cibinong, Indonesia and other additional collections that are carried out from June to July 2018 and then analyzed by Principal Component Analysis (PCA) to determine the population grouping. The result showed a high variation on the scale range of anterior prefrontal, posterior prefrontal, frontal, parietal, preocular, postocular, loreal, temporal, upper labial, lower labial, and dorsal scales. Ventral and subcaudal scales in male and female specimens show high variation in the total scale count, the ratio comparison of tl: SVL measurement, indicated the sexual dimorphism. Prefrontal (anterior-posterior) and frontal scales show high variation and difficult to distinguish between each locality at the subspecies level and suggest it to be intra-specific variation. There is no significant grouping were found between populations from data on morphological variations.

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. 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

Tokay gecko (Gekko gecko) is a large-sized gecko from the genus of Gekko, which is most commonly found from South Asia, southern China, and Southeast Asia. In Indonesia, these species are common to inhabit human-modified habitat in Sumatera, Borneo, Java, Bali, Lesser Sundas, Sulawesi, and Moluccas. In recent years, the demand for Tokay gekko with high use-value in both national and international markets has increased, one of which is used for traditional medicine. This situation raised the concern on the decreasing of the wild population and the validity of captive breeding programs that produced a large number of individuals. Several reports had estimated millions of individuals have been exported from Indonesia either legally or illegally, however, the exact number never been reported. The purpose of this study is to evaluate the trend on the harvested Tokay gecko and its origin based on the source code information. The data were collected from government records, including specimens harvested from the wild and specimens produced from captivity during 2013 - 2018 (six years). The results showed that the legally exported specimens were sourced from wild (W) and captive breeding (C or F). The total numbers of individuals exported from the wild harvest are 97.146, and all export realization is below the wild harvest quota. However, there are the large numbers of individuals exported and declared as specimens produced from the captive breeding facilities (6.965.000 with source code F, and 1.236.000 with source code C). More importantly, the high level of specimens produced from captive breeding facilities is unlikely to match with the biological capacity of this species. Therefore, we predict that specimens labeled captive breeding were likely sourced from the wild.

Abstract

Exploitation freshwater turtle for local consumption, medicine, and pet in several parts in Asia caused the declining populations in the wild. The purpose of this study is to evaluate of turtle harvest that listed in Appendix CITES in South Sumatra and Central Borneo. We reported the trading network of the three most exploited turtle species in South Sumatera and Central Borneo. We visited the largest middleman in the two provinces and collect the data that comprises the harvest number, prices, trade flow, catching area, and the level of harvest for local consumption. During our survey in Sampit (Central Borneo) (one week in April 2019), we recorded 667 kg of turtles were sent to a middleman and harvested from Jemaras and Sembuluh district. This amount comprises 549 individuals of Cuora amboinensis, 173 Siebenrockiella crassicollis, and one individual of Cyclemys dentata. Contrary to that, in Palembang, we did not find any delivery of turtle from the hunters. However, 387 individuals of C. amboinensis and 132 individuals of S. crassicollis were found in a middleman pool. We also recorded that local people in Central Borneo consumption of turtle meat. The national quota of C. amboinensis in Central Borneo and South Sumatra are 1700 and 2000 individuals for 2019. The national quota of S. crassicollis in South Sumatra is 500 individuals, while Central Borneo does not have any quota for this species. The realization of these wild-caught turtles indicates an over harvesting beyond the annual harvest quota. Moreover, the two middlemen are indicated to carry illegal carapace trading, although the scientific authority recommended to ban the carapace trade.

Abstract

Huia masonii (Boulenger, 1884) or Javan Torrent Frog is one of the frogs that are endemic on the island of Java. The presumption of two different forms of Huia's morphology according to Manthey and Dezer’s publication makes a systematic study of these species among their populations necessary. In this study, a systematic study of H.masonii was conducted between populations with a morphological approach to determine differences in character between populations, taxonomic status and phylogeny between populations. A total of 111 adult specimens (62 males and 49 females) from each population with good condition were observed morphologically. Data analysis was performed using Principal Component Analysis (PCA) and UPGMA Clustering. The results of this study indicate that there are no fundamental differences in the characteristics of each population so that there are no characters that can be used as diagnostic characters. The absence of this diagnostic character also makes the taxonomic status of H. masonii morphologically unchanged. Besides relationship between populations is still close to one another morphologically

Abstract

Traditionally, the genus Philautus Gistel, 1848 contains small Rhacoporid frogs that lack vomerine teeth and a direct development tadpole stage. In Java, this genus consists of 3 species, including Philautus aurifasciatus, Philautus jacobsoni, and Philautus pallidipes. It is known that Philautus aurifasciatus and Philautus jacobsoni are sympatric species from Mount Ungaran and are morphologically difficult to distinguish. Therefore, information is needed through the phenetic characters of each population in the area to identify differences in their morphology. This study aimed to analyze the morphological characteristics of  Bush Frog Philautus spp. on Mount Ungaran in terms of meristic character through a direct field survey and comparison methods. Furthermore, it was conducted by observing 32 specimens of Philautus spp. from Mount Ungaran and compared with the Philautus aurifasciatus from Mount Gede Pangrango with 18 meristic characters. The results showed that Philautus spp. is similar to Philautus aurifasciatus in terms of their meristic characters. The results of the meristic analysis showed that Philautus spp. has a variety of dorsal colors from brown, purple, green, and gray with two types of patterns including patterned groups (resembling letters H, X, and V) and abstract. Furthermore, the throat, stomach, and lower thighs are granular with three snout shapes (protruding, round, and sloping). It has a loreal oblique tympanum and canthus rostralis. The forelimbs are not webbed while the hindlimbs are half webbed, and the inner metatarsal is an elongated oval in shape. Meristic analysis provides a basis for strengthening the taxonomic status of Philautus spp on Mount Ungaran, as well as information the distribution in Mount Ungaran.
