By examining mitochondrial DNA phylogeny using 2424bp of sequence data 12S rRNA, tRNAval, and 16S rRNA genes, we evaluated the taxonomic relationships among Javan litter frogs Leptobrachium hasseltii from southern Sumatra, Java, and Bali. Leptobrachium hasseltii formed a well-supported monophyletic group, which comprised two major clades. One major clade represented the southern Sumatran and Javan populations and the other consisted of the population from Bali. The Javan and southern Sumatran clade included two subclades: the West Javan-southern Sumatran group and the Central Javan group. The genetic divergence between the two major clades (Bali vs. Java-Sumatra) suggested their separation happen at species level. Further studies using morphological and acoustic data are needed to determine the taxonomic status of Bali population.

Javan Hawk Eagle is one of the three keys species of the Gunung Halimun Salak National Park and endemic to the island of Java. Protecting the active Javan Hawk Eagle nesting tree is one of the efforts to increase the success rate of Java Hawk Eagle breeding so that information on the distribution and characteris-tics of Javan Hawk Eagle nesting tree is needed. Field exploration was carried out to determine the existence of the Javan Hawk Eagle nest. There were 10 individuals of Javan Hawk Eagle nesting trees which consisted of 5 species namely Rasamala, Huru, Damar, Leng-sar and Manggong with tree architecture models of rauh, massart, scarrone and aubreville, tree height between 26-55 m and height of nests between 18-41m. The Javan Hawk Eagle nesting trees grow in primary, secondary, and plantation forests in a height between 670- 1295 masl, with a steep and very steep slope, the majority of the dis-tance from the river is less than 100 m and the majority of the dis-tance with ecotone is less than 600 m. Javan Hawk Eagle nest on Damar is the first finding at Gunung Halimun Salak National Park.

Full textAbstract:
Habitat loss and forest fragmentation have negative impacts on Javan Slow Loris Nycticebus javanicus, a Critically Endangered nocturnal primate endemic to Java. Reports confirmed that less than 9% of forest area remains on Java Island. One of the remaining natural habitats of the Javan Slow Loris is the fragment of Kemuning Forest in Temanggung Regency, Central Java. The purpose of this study was to determine resource selection and habitat variables that determine the presence of Javan Slow Loris. Habitat variables measured were basal area, tree connectivity, crown coverage on tree stage, slope, elevation, and distance to river. Data analysis performed was logistic regression, likelihood ratio test, and Akaike’s Information Criterion with a backward elimination procedure. We also used direct observation and interviews with locals to collect data on environment and anthropogenic features of this forest. The results showed that the Javan Slow Loris uses resources selectively on a microhabitat scale. The habitat factors that influence the probability of resource selection by the species are canopy cover and slope. Habitat characteristics preferred by the Javan Slow Loris in Kemuning Forest are secondary lowland tropical rainforest with dense canopy cover located on a steep slope with low level of habitat disturbances. Although this study uses a small sample size, the expectation is that the results can be used as preliminary information for the habitat and population management of Javan Slow Loris in Kemuning Forest to guide conservation efforts and design management strategies.

The grouping system and local distribution pattern analysis of Javan green peafowl (Pavo muticus muticus, Linnaeus 1758) population in Baluran and Alas Purwo National Parks, East Java, Indonesia. Biodiversitas 19: 1690-1695. The Javan green peafowl population lives in a group system. The population applies a small size group system. The distribution of the birds in Java Island is randomly fragmented and isolated in several types of habitat and each has a small number of individuals in every group. Baluran and Alas Purwo National Parks, East Java, Indonesia as part of Javan green peafowl (Pavo muticus muticus, Linnaeus 1758) distributions have been selected for the study on the grouping system and the analysis of local distribution. The research was aimed at obtaining data and information on the grouping system and local distribution of Javan green peafowl population in Baluran and Alas Purwo National Park. The number of individuals and groups was counted by applying a transect method and a concentration method on every type of habitat where peafowls are present. The distribution pattern data were analyzed by using a formula (Ludwig and Reynolds 1988). The results indicate that Javan green peafowl population is living in small groups (2-4 birds). There are 5 types of Javan green peafowl groups in Baluran National Park (BNP) and Alas Purwo National Park (APNP). The dominant group is adult female group consisting 3 individual members. The leader of the group is a female bird. Adult males live in solitary. The group system among Javan green peafowl populations is a strategy of the birds. Local distribution of Javan green peafowl populations in Baluran and Alas Purwo National Parks is mostly in the form of clumped dispersion.

Full textAbstract:
Background: The Banteng population in Ujung Kulon National Park (TNUK) is less than 500 individuals. The habitat of Java Banteng in conservation areas has largely decreased. One approach to assessing the current status of biodiversity at all levels, especially in endangered species, is to use geospatial technology such as remote sensing and geographic information systems combined with spatial data science. This study aims to create a spatial model of the suitability of the Javan Banteng habitat in the TNUK area and identify the use of the Java Banteng habitat and environmental variables that affect the presence of Javan Banteng. Methods: This research data was collected through coordinate data for stool sampling and data from BTNUK using a method called maximum entropy (maximum). The analysis used the Relative Use Index, Maximum Entropy modeling, and Relative Abundance Index. Results: Based on research, the use of habitat by Java Banteng with the value of making a spatial distribution model can be analyzed by analyzing the contribution of environmental variables based on the level of contribution in percent and the results of the jackknife test, namely the percentage of contribution of environmental variables in this study showed that environmental parameters, slope (37.6%) were the highest parameters, followed elevation (25.8%), land cover (25.3%), and NDVI (6%), rivers (5.3%). The analysis of five environmental variables used in making the Javan Banteng distribution model showed that at an altitude of 45 meters above sea level, Java Banteng preferred to show 95%. The graph decreased at an altitude above 45 mdpl, and Java Banteng at 200 meters above sea level looked at 0%. Conclusions: Javan Banteng do not like or do not choose places with altitudes ranging from 200 - 625 meters above sea level.

SummaryThe Javan Hawk-eagle Spizaetus bartelsi is endemic to the island of Java. Severe habitat fragmentation and small population size, aggravated by illegal hunting have put this rainforest species on the list of threatened bird species. Intensive searching since 1986 resulted in the discovery of a large number of localities additional to the historic ones. All known locality records of Javan Hawk-eagle have been scrutinized and are listed in the present paper. Confirmed post-1980 records are from 24 forest fragments of varying sizes: 10 (including 28 discrete localities) in west, seven (including 14 discrete localities) in central and seven (including 20 discrete localities) in east Java. The configuration of available habitat in forest clusters is evaluated. The co-existence with other threatened bird taxa, and the need for further field surveys and studies of the Javan Hawk-eagle are discussed.

On April and September 2006, preliminary study to know the distribution, population status and habitat of the Javan moustached parakeets (Psittacula alexandri alexandri Linnaeus 1758) were conducted in the Baluran and Alas Purwo National Parks (East Java) and in the Tilu Geder Mountain Forests and in the Darmaga IPB Campus Parks (West Java). Direct and indirect observations were used in this research. The results are found only 2 individuals of birds in the Darmaga IPB Campus Parks. However, 45 species of plants were recorded as the natural food resources for the Javan moustached parakeets in the fields. Almost 60 percent parts of plants i.e., fruits were food by birds, even if those birds are more frugivorous. Some species of plants were known as the nesting trees for the species, namely: Tectona grandis, Acacia lecophloea, Azadirachta indica, Tetrameles nudiflora and Eucalyptus deglupta. The Javan moustached parakeets have needed mangrove forests, beach forests, evergreen forests and old teak forests for their activities. The population and their habitat of javan parakeets are threatened by forest fragmentation effects and over hunting.

Full textAbstract:
Red and yellow soils from tropical regions are generally more mature than their subtropical counterparts. Most of these soils contain kaolin as the dominant clay mineral. Exchangeable aluminium (Al) generally balances permanent negative charges and occupies strongly acidic exchange sites of the soil clay. The objective of this study was to identify those clay minerals that are most highly implicated in contributing exchangeable Al to red and yellow soils collected from the Islands of Okinawa and Java. All soils exhibited an acid reaction but varied in their exchangeable Al content and clay mineralogy. Clay content was high in all Javan soils but varied in those from Okinawa. Javan soils were dominated by kaolinite, and Okinawan soils by an association of illite and halloysite. However, 2 : 1-2 : 1 : 1 intergrades were significant components in both the Oku red soils (Okinawa Island) and the Pamagersari red soils (Java Island). Javan soils were characterised by a more mature (advanced) state of weathering than those from Okinawa. The source of exchangeable Al was halloysite in Okinawan soils and 2 : 1-2 : 1 : 1 intergrades in Javan soils.

Full textAbstract:
The Javan gibbon Hylobates moloch is confined to the last remnants of rainforest on the island of Java, Indonesia. As of 2002, the species has been recorded in 29 forest areas, and the wild population is conservatively estimated at 4100-4500 individuals. Over 95% of the gibbons are in populations of >100 individuals, and the four largest areas support populations of >500 individuals each. In 2003, 56 Javan gibbons were maintained at eight Indonesian zoos, 15 at four Indonesian wildlife rescue centres, with five potential breeding pairs. There is no evidence that the species has bred successfully in captivity in Indonesia. Outside the range country, 48 Javan gibbons were maintained at ten institutions in nine countries, with six breeding pairs. The total ex-situ population is some 120 individuals, the majority of which is wild-caught. At present most initiatives relating to the conservation of the Javan gibbon have targeted small isolated forest areas and the ex-situ population, whereas in-situ protection of the largest populations in the wild has been largely ignored. Significant populations are currently found in unprotected forests. The large captive population of Javan gibbons within Indonesia allows, with improved co-operation, to set up an integrated captive- breeding programme. This should, not be seen, however, as a means to improve the conservation status of the wild Javan gibbons, which needs to be achieved through protection of remaining habitat, but could be used for improving the prevailing low levels of conservation awareness in Java.

Full textAbstract:
Javan langur (Trachypithecus auratus É. Geoffroy, 1812) is categorized by IUCN as a vulnerable primate species since 2008 and protected under 2018 LHK regulation. They can be found across Java Island, also in the Watangan Puger Nature Reserve (WPNR), East Java. There is no information about the population and habitat characteristics of Javan langur in WPNR except their existence. This research study aims to estimate the population structure, population density, and habitat characteristics of the Javan Langur in the WPNR, within the area of 2.6 ha. Three concentration points for daily observations were determined for 3 days. A combination of concentration count with scan sampling observation method at intervals of 30 minutes every hour of observation was done to get the data of density, position, population structure, and plant species preferred by Javan langurs. The important value, diversity Shannon-Wiener index, and plant species preferred were also analyzed. There are 26 population composed of two groups of the Javan langur occupying an area of 1,118 ha (43%). The population size estimatation for the first group was 17 individuals with a population density of 15.17 individu/ha, while that for the second group was 9 individuals with a population density of 8.02 individu/ha. The twenty-six Javan langurs are composed of complete age structure such as adult 69%, sub-adult 15%, and infant 16%. The Javan langur population was mostly found in the vegetation structure of Syzygium jambos (jambu hutan) to Pithecellobium dulce (asam manila) (IV = 45.47 to 3.88). Total 24 tree species are found in WNPR, most of the trees are used by the Javan langur as food and cover. The tree community in WPNR has medium diversity with value of 2.28. Furthermore, the Javan langur prefer Artocarpus elasticus (bendo) and Syzygium jambos (jambu hutan) at the upper strata (> 15 meters) than other trees and strata. Most of them are actively walking or jumping (locomotion) during the activity observed at the tree community.

Full textAbstract:
The Javan gibbon (<i>Hylobates moloch</i>) is endemic to the island of Java and its distribution is restricted from the western tip of Java to the Dieng Mountains in Central Java. Unlike the other known habitats that hold a large population of Javan gibbons, the Dieng Mountains have not been protected and experience various threats. This study, which was conducted in 2018 and 2021, aimed to provide an update of the current density and population size of Javan gibbons in Dieng after the most recent study in 2010 and to investigate their relationships with habitat characteristics (vegetation and elevation). The triangulation method and a new acoustic spatial capture-recapture method were used to estimate group density. A new approach for extrapolation, based on the habitat suitability model, was also developed to calculate population size. The results show that the Javan gibbon population in the Dieng Mountains has most likely increased. The mean group density in each habitat type was high: 2.15 groups/km<sup>2</sup> in the low suitable habitat and 5.55 groups/km<sup>2</sup> in the high suitable habitat. The mean group size (3.95 groups/km<sup>2</sup>, n = 20) was higher than those reported in previous studies. The overall population size was estimated to be 1092 gibbons. This population increase might indicate the success of conservation efforts during the last decade. However, more effort should be made to ensure the long-term future of this threatened species. Although the density significantly differed between habitat suitability types, it was not influenced by the vegetation structure or elevation. A combination of multiple variables will probably have a greater effect on density variation.

Currently the critically endangered Javan Rhino is only found in Ujung Kulon National Park (NP) in Banten province of west Java, Indonesia. As per annual camera trapping surveys being carried out by the Ujung Kulon NP authorities the current Javan rhino population is estimated to be 72 of which 38 are male and 33 are female. The gender of a further individual could not be determined from camera trap photographs due to poor quality. Out of the 72 Javan rhinos 15 are calves and for the first time in a decade this gives us cause to be hopeful for the critically endangered Javan rhino inhabiting its lone abode in the world. While the trend in rhino numbers is increasing (with at least one new birth recorded every year since 2012), efforts to look for a suitable second habitat for Javan rhinos within Indonesia continues. This is based on sound scientific analysis among key rhino conservation partners in Indonesia, however no consensus on a potential site for Javan rhino has yet been reached. The species remains at risk from a range of threats—from infectious diseases to natural disasters, including tsunamis. In December 2018, Arak Krakatoa erupted causing tsunamis in both Sumatra and Java. Poaching is also a threat although no poaching incidents have been reported in the past two decades due to enhanced vigil by Rhino Protection Units in Yayasan Badak Indonesia (YABI). The Rhino Protection Units work in tandem with the Ujung Kulon NP rangers under an MOU signed by YABI and Ujung Kulon NP authorities with due approval from the Ministry of Environment and Forestry, Republic of India, while the Javan rhino camera trapping exercises in Ujung Kulon NP are carried out by the Rhino Monitoring Unit (RMU) of the Park. (Up until October 2019 the RMU was known as the Rhino Observation and Activity Management (ROAM) in association with WWF-Indonesia). Since January 2020, the camera trapping of Javan rhinos in Ujung Kulon NP has been conductedo by RMU members of the Park and is being funded by the International Rhino Foundation (IRF) through its Indonesian partner YABI. There are also programmes to improve the habitat, and an exercise in the removal of the invasive palm, Arenga Palm is continuing as it blocks out sunlight, inhibiting the germination process and disrupting the growth of vegetation, which rhinos feed on. This habitat improvement activity is being supported by the International Rhino Foundation (IRF) through its Indonesian partner YABI. Actuellement, le rhinocéros de Java, en danger critique d'extinction, ne se trouve que dans le parc national (PN) d'Ujung Kulon, dans la province de Banten, dans l'ouest de Java, en Indonésie. Selon les enquêtes annuelles de pièges photographiques, menées par les autorités du PN de Ujung Kulon, la population actuelle du rhinocéros de Java est estimée à 72, dont 38 mâles et 33 femelles. Le sexe d'un autre individu n'a pas pu être déterminé à partir des photos de pièges photographiques en raison de la mauvaise qualité. Sur les 72 rhinocéros de Java, 15 sont des jeunes et, pour la première fois en une décennie, cela nous donne de l'espoir pour le rhinocéros de Java, en danger critique d'extinction, et vivant dans son unique habitat restant au monde. Alors que la tendance du nombre de rhinocéros est à la hausse (avec au moins une nouvelle naissance enregistrée chaque année depuis 2012), les efforts pour rechercher un deuxième habitat approprié pour les rhinocéros de Java en Indonésie se poursuivent. Ceci est basé sur une analyse scientifique solide parmi les principaux partenaires de conservation des rhinocéros en Indonésie, mais aucun consensus sur un site potentiel pour le rhinocéros de Java n'a encore été atteint. L'espèce reste menacée par une gamme de menaces—des maladies infectieuses aux catastrophes naturelles, y compris les tsunamis. En décembre 2018, Arak Krakatoa a éclaté, provoquant des tsunamis à la fois à Sumatra et à Java. Le braconnage est également une menace bien qu'aucun incident de braconnage n'ait été signalé au cours des deux dernières décennies en raison de la vigilance renforcée des unités de protection des rhinocéros à Yayasan Badak Indonésie (YABI). L'Unité de surveillance des rhinocéros du parc travaille en tandem avec les rangers du PN d'Ujung Kulon dans le cadre d'un protocole d'accord signé par YABI et les Autorités du PN d’Ujung Kulon avec l'approbation du Ministère de l'environnement et des forêts, République de l'Inde, alors que les exercices de piégeage photographique de rhinocéros de Java dans le PN UK ont été effectués par l'Unité de surveillance des rhinocéros (RMU) du parc. (Jusqu'en octobre 2019, la RMU était connue sous le nom d’Observation et gestion des activités du rhinocéros (ROAM) en association avec le WWF-Indonésie). Depuis janvier 2020, le piégeage photographique des rhinocéros de Java dans le PN d'Ujung Kulon est réalisé par les membres de la RMU du parc et est financé par la Fondation Internationale pour le rhinocéros (IRF) via son partenaire indonésien YABI. Il existe également des programmes pour améliorer l'habitat et un exercice d'élimination du palmier envahissant, Arenga Palm, se poursuit car il bloque la lumière du soleil, inhibant le processus de germination et perturbant la croissance de la végétation, dont les rhinocéros se nourrissent. Cette activité d'amélioration de l'habitat est soutenue par la Fondation Internationale pour le rhinocéros (IRF) via son partenaire indonésien YABI.

Full textAbstract:
Indonesia is at the epicenter of the Asian Songbird Crisis, i.e., the recognition that the cage bird trade has a devastating impact on numerous imperiled bird species in Asia. The Javan pied starling Gracupica jalla, only in the last five years recognized as distinct from the pied starlings of mainland Southeast Asia, has been declared extinct the wild in 2021. Up until the 1980s, it used to be one of the most common open countryside birds on the islands of Java and Bali, Indonesia. From the early 2000s onwards, the species is commercially bred to meet the demand from the domestic cagebird trade. We conducted 280 market surveys in 25 bird markets in Java and Bali between April 2014 and March 2020, with 15 markets being surveyed at least six times. We recorded 24,358 Javan pied starlings, making it one of the most commonly observed birds in the markets. We established that, conservatively, around 40% of the birds in the market were sold within one week and used this to estimate that at a minimum ~80,000 Javan pied starlings are sold in the bird markets on Java and Bali. The latter represents a monetary value of USD5.2 million. We showed that prices were low in the 1980s, when all birds were sourced from the wild. It became more varied and differentiated in the 2000s when a combination of now expensive wild-caught and cheaper captive-bred birds were offered for sale, and prices stabilized in the 2010s when most, if not all birds were commercially captive-bred. Javan pied starlings are not protected under Indonesian law, and there are no linked-up conservation efforts in place to re-establish a wild population on the islands, although small-scale releases do take place.

Full textAbstract:
Animal-plant interactions are crucial for understanding the ecological dynamics and predicting ecosystem changes. This study explores the role of the invasive plant Maesopsis eminii in the Bodogol Nature Reserve, Gunung Gede National Park, West Java, Indonesia, focusing on its interaction with diurnal vertebrate species. Primates, including Javan gibbon and Javan langur, were identified as primary consumers of Maesopsis eminii, with Javan gibbon showing the highest consumption rates. Dietary analysis revealed that both primate species utilized M. eminii fruits and leaves, whereas Javan gibbons relied more on Maesopsis eminii than Javan langurs. Other vertebrates, such as squirrels and birds, are occasional visitors with minimal fruit consumption. This study highlights that Maesopsis eminii is a primary resource of Javan gibbon, Javan langur, and Javan surili. This nearly year-round fruiting plant is crucial for supporting primate populations, especially given its contribution to their diet. Considering the mutualistic interaction between Maesopsis eminii and its visitors, the Javan gibbon was the only species that probably dispersed seeds through endozoochory, making this primate species a crucial part of the dispersal of Maesopsis eminii in Gunung Gede National Park. Because invasive plants can threaten native flora and fauna, future studies must emphasize balancing the beneficial and detrimental effects.

Dietary study of carnivores has garnered a great deal of attention for a very long time since it provides information for comprehending ecological processes and tracking the economic effects of animals on food production. Few studies reported alternative prey that is detrimental to food production, such as rodents and insects, in addition to the numerous studies on livestock predation. Therefore, this study aims to provide information on the diet composition and overlap of two mesocarnivore species, Javan mongoose (Urva javanica) and leopard cat (Prionailurus bengalensis), in Java, Indonesia. The macroscopic observation technique was applied for identifying food remnants found in the 90 feces of the mongoose and 100 feces of the cat collected in 2018. Twenty three and 21 taxa of prey were found in the leopard and Javan mongoose feces. Rodentia was the most frequent taxa found in the feces of both species, followed by Galliformes. Insects comprised the majority of diet items but at low frequencies. Two mesocarnivores were specialists (Levin’s index of leopard cat: 0.08; Javan mongoose: 0.26) with fairly high diet overlap (Pianka’s index = 0.78). The results provided compelling evidence of the positive and negative impacts of mesocarnivores on food production in Java.

Javan coucal (Centropus nigrorufus) is one of the endemic birds of Java that has limited distribution in coastal areas. This study aimed to determine the spatial distribution and habitat preference of javan coucal in Wonorejo Region, in the East Coast of Surabaya. The spatial distribution and habitat preference were analyzed using dispersion index (ID) and Jacob index respectively. The results showed that Javan Coucal distribution was clumped, indicated by ID value > 1 for mangrove forests, inactive ponds and active ponds. The Jacob index (Dhi) were 0,75, 0,41 and -0,68 for inactive ponds, mangrove forests and active ponds, respectively. This result indicated that javan coucal preferred inactive ponds and the mangrove forests, and they tend to avoide active pond. The habitat factors affecting the javan coucal encounters were perch height (t=2,655; p=0,014), distance from coast (t=4,539; p=0,000) and air temperature (t=2,675; p=0,013). The regression equation was Y=67,041+0,678 (perch height) + 0,020 (distance from coast)-2,373(air temperature). Keywords: habitat preference, javan coucal, spatial distribution, Wonorejo

Abstract Javan Hawk-Eagle (JHE, Nisaetus bartelsi) is an endemic species in Java Island and an important biological indicator of ecosystem health. The government has issued regulations to protect this species and increase the population by 10% from 2015 until 2019. East Java has the largest JHE potential habitat in Java Island based on a previous study using satellite images of 2002. Therefore, the current habitat distribution of JHE’s is essential for getting knowledge about patch dynamics in JHE’s habitat. This study’s objective was to analyze patch dynamics of JHE’s habitat from 2002 until 2015 and validate habitat distribution. Previously predicted probability map (2002) of JHE’s were updated using Landsat 8 satellite images of 2015 and was validated through ground-truth checked. Results showed that the distribution of JHE’s habitat after validation is 28 patches, which is covered 4766.26 km2. The dynamics that occur in the JHE’s patch are patch lost(1 patch), patch area decreased (5 patches), patch area increased (13 patches), new patch (4 patches), and merged patch. After validation, there are six newly identified patches, and one patch area increased. The total area increased by 2156.14 km2 or 82.61% of the total area occupied by JHE’s in 2002. About 39.89% of total habitat patches were located inside the protected area. This study recommends continuing monitoring activities on habitat patches, including potential habitat patches in lowland areas, and proposing conservation activities based on habitat patch dynamics that occurred from 2002 to 2015.

<p>Javan rhino (Rhinoceros sondaicus) is one of the rare animals with critically endangered status. The Ujung Kulon National Park (UKNP) is one of javan rhino habitat in Indonesia. Every year the monitoring program for javan rhino in UKNP was performed to identify the animals. This research was aimed to analyze the population structure of javan rhino based on the records data from 2011 to 2019 in UKNP. Research showed that the natural increase (NI) and birth rate (BR) values were 17.34% (moderate) and 67.33% (high) respectively. The net return rate (NRR) value was 15.38% (male) and 14.28% (female). The NRR value in the present study was lower than 100% and caused by less number of animals in a population for 30 years of breeding length. Despite this, the inbreeding rate of javan rhino at UKNP in 2019 was 0.01 (low). It was concluded that the natural increase of javan rhino at UKNP showed a good parameter but the population number needs to be increased.</p>

Full textAbstract:
All members of the family Rhinocerotidae have the need to wallow in mud or water to protect their skin from sun damage, remove ectoparasites and for thermoregulation purposes. Just 72 wild Javan rhino (Rhinoceros sondaicus) remain on the planet, all located in their last stronghold in Ujung Kulon National Park (UKNP), West Java, Indonesia. Javan rhinos need to wallow regularly throughout the year, yet the role wallows play in their behaviour and the importance to the species remains little understood. In this study, we identified, mapped and studied 35 wallows in eastern UKNP, where rhinos were active. We spatially mapped and recorded each wallow’s characteristics. We examined rhino wallowing behaviour using 392 remote camera trap videos, taken across UKNP during a five-year study from 2011 to 2016. We identified and categorised eight behavioural patterns at and near wallows related to rhino daily activities and found that wallows have several key features for the Javan rhinos. Findings revealed that Javan rhinos, who construct the wallows themselves, choose sites with 75% shade cover and often at an elevation. Analysis of the rhino calls from camera trap videos taken at and near wallows, identify seven vocalisation descriptors with accompanying sonograms, a first for this rare and shy rainforest species. We discovered that Javan rhino utilise wallows not only for thermoregulatory function, but also as sites of interaction and communication. This has important implications for conservation and potential translocation of rhinos, which will require finding sites with suitability for the construction of wallows. Tous les membres de la famille des rhinocérotidés ont besoin de se vautrer dans la boue ou l'eau pour protéger leur peau des dommages du soleil, éliminer les ectoparasites et à des fins de thermorégulation. Il ne reste que 72 rhinocéros de Java (Rhinoceros sondaicus) sauvages sur la planète, tous situés dans leur dernier bastion du parc national d'Ujung Kulon (UKNP), à West Java, en Indonésie. Les rhinocéros de Java doivent se vautrer régulièrement tout au long de l'année, cependant le rôle des mares boueuses dans leur comportement et leur importance pour l'espèce restent peu compris. Dans cette étude, nous avons identifié, cartographié et étudié 35 mares boueuses dans l'est de l’UKNP, où les rhinocéros étaient actifs. Nous avons cartographié spatialement et enregistré les caractéristiques de chaque mare. Nous avons examiné le comportement des rhinocéros se vautrant dans la boue en utilisant 392 vidéos de pièges photographiques à déclenchement à distance, vidéos prises sur l’ensemble de l'UKNP au cours d'une étude de cinq ans de 2011 à 2016. Nous avons identifié et catégorisé huit modèles de comportements à proximité de et aux mares boueuses liées aux activités quotidiennes des rhinocéros et nous avons constaté que les mares boueuses ont plusieurs caractéristiques clés pour les rhinocéros de Java. Les résultats ont révélé que les rhinocéros de Java, qui construisent eux-mêmes les mares, choisissent des sites à 75% d'ombre et souvent en altitude. L’analyse des appels vocaux enregistrés dans les vidéos prises à l’aide de pièges photographiques à proximité de et aux mares boueuses, identifie sept descripteurs de vocalisation accompagnés de leurs sonogrammes, une première pour cette espèce rare et timide habitant en forêt tropicale. Nous avons découvert que le rhinocéros de Java utilise les mares non seulement pour leur fonction thermorégulatrice, mais aussi comme sites d'interaction et de communication. Cela a des implications importantes pour la conservation et le transfert potentiel des rhinocéros, et nécessitera de trouver des sites convenant à la construction de mares boueuses.

Full textAbstract:
Javan Langur (T. auratus) is well-known as one of endemic primates from Java, Bali and Lombok Islands. The activities of land clearing, vegetation conversing, wild hunting and illegal wildlife trading are the main causes of the extinction of the Javan Langur. It can be used as an important issue for conservation action by making prediction maps of suitable habitat potential, especially for species facing a high risk of extinction in the wild. We were documenting an information about potential habitat for Javan langur using spatial suitability model in order to provide rigorous information as the basis for conservation activities of Javan langur in TNBTS. We used Landsat-8 TM image and geospatial data to support analysis as a representative of environmental parameters in order to develop the habitat model. We were using maximum entropy (MaxEnt) algorithm refers to Javan langur presence or absence. The results showed that the suitability of the Javan langur habitat in TNBTS has an excellent model accuracy level with an AUC (Area Under the Receiver Operating Characteristics) value of 0.964 and a standard deviation of 0.961. Parameters with the highest response values here are elevation, NDVI (Normalised Difference Vegetation Index) and temperatures.

New locality records and a range extension of the Javan endemic Pearly Tree Frog, Nyctixalus margaritifer Boulenger, 1882 are reported from Central Java and East Java. Our new data include the easternmost record in Java, a record from the eastern edge of Bromo Tengger Semeru National Park, which is approximately 142 km west of the species&rsquo; type locality in Gunung Willis in East Java. This tree-frog species inhabits undisturbed rainforest with a dense canopy and vegetation at elevations up to 1,200 m a.s.l. Based on a morphometric analysis of newly collected specimens, we found observable differences in several morphological characters. However, more specimens are needed to confirm the taxonomic status of the rare, endemic, and poorly known N. margaritifer.

Full textAbstract:
The colubrid snake Dendrelaphis subocularisis distributed throughout Indochina, the southern limit of its range corresponding with the Isthmus of Kra, an important biogeographic barrier that separates the Indochinese biota from the Sundaic biota. This study presents five museum specimens that represent a hitherto unknown population that inhabits the Sundaic island Java. Thus, the distribution of Dendrelaphis subocularisis disjunct, with the Javan population being isolated by 2000 kilometres from the nearest mainland population. Principal Components Analysis was applied to morphological data taken from the five Javan specimens as well as from 26 museum specimens of Indochinese origin. Regression analysis of the spatial pattern of the resulting scores indicated that: 1) the Javan population exhibits negligible morphological differentiation, and 2) a phenetic cline exists from which the Javan population does not appreciably deviate in spite of its isolated status. These findings suggest a vicariant origin of the Javan population entailing climatic changes and formation of land bridges during Pleistocene glaciations. The Javan and Indochinese populations represent independent sister lineages, and are therefore valid species within the framework of a lineage-based species concept. However, to conform to current taxonomic practice, the Javan population is not named separately due to the fact that it is not diagnosable.

Full textAbstract:
Javan slow loris (Nycticebus javanicus) is one of the endemic wildlife on Java Island. This species owns particular characteristics, including arboreal, solitary, and nocturnal natures. The species is threatened due to habitat loss and illegal trafficking. Nevertheless, their current geographic distribution remains unclear and environmental factors impact on these species is mostly unknown. This study aims to predict the habitat suitability of javan slow loris in the Conservation Management Forest Unit area of Mount Halimun Salak Forest Group. The study employs a species distribution modeling approach using Maximum Entropy. The presence data of javan slow loris was collected from the radio-telemetry devices used in post-release monitoring. The modeling utilizes elevations, distance from the settlements, slopes, and land covered as its environment variables. The result shows that 52% of the study areas, or 54,669 ha are suitable as the habitat of N. javanicus. Since as the largest protected area on Java Island, Gunung Halimun Salak National Park is one of the natural habitats that are pivotal for this species. This study provides essential documentation for developing management strategies within protected areas. Hence, the result of the study could serve as one of the factors in the determination of animal release location in the future.
