<p>Javan Langur (Trachypithecus auratus) is one of endemic primates in Indonesia and classified into vulnerable level. Based on its morphological characteristic and geographic area, Javan Langur divided into 2 subspecies, those are Trachypithecus auratus auratus and Trachypithecus auratus mauritius. The identification of its morphological characteristic and genetic in species or subspecies level is important before releasing because it is correlated with inbreeding grouping and releasing place. The aim of this study is to identify the Javan Langur (Trachypithecus auratus) in Javan Langur Center (JLC) Coban Talun-Batu based on D-Loop sequence. The blood sample used in this study was taken from two adult female Javan Langur named Ijem and Embun, that have different morphological characteristics. Both (primates) are suggested to be T.a.mauritius and T.a.auratus respectively. The amplification of D-Loop sequence by mean of PCR technique was performed using specific designed primers forward D-LoopRs 5’-GTACTTAACTCCACCACCAA-3’ and reverse D-LoopRs 5’-GTTGAGTTGGGTATGCTCGA-3’. The phylogenetic tree reconstruction based on MEGA 5 using Maximum Likelihood (ML) method and pairwise distance analysis with Kimura-2 parameter model shows that Ijem and Embun are placed in different clade. Pairwise distance from those samples value is 11,4%, it prove that they are interspecies. This result supports the morphological characteristic and previous research used Cyt-b sequence, Ijem is Trachypithecus auratus mauritius and Embun is Trachypithecus auratus auratus. </p><p>Keywords : Identification, Javan Langur (Trachypithecus auratus), D-loop, Javan Langur Center</p>

The Tenasserim lutung Trachypithecus barbei was previously known from museum specimens and field observations only. We discovered a zoo specimen and present the first confirmed evidence for the continued existence of the species since 1967. We describe the cranial pelage and coloration characteristics of this species which were previously unknown. We present first molecular evidence for recognizing T. barbei as a distinct species and for assessing its phylogenetic affinities relative to other members of the genus Trachypithecus. We document the taxonomic history of T. barbei and present a distribution map based on a compilation of all known locality records.

<p>Javan Langur (Trachypithecus auratus) is an endemic langur in Indonesia which classified as vulnerable primate. Some researches divided Javan Langur species into some subspecies, yet was not described properly. Cytochrome-b sequence from mitochondrial DNA is able to determine samples between and intra-species as well. This study aimed to identify the Javan Langur (Trachypithecus auratus) samples named Andin (@&amp;) and Bobby (B&amp;), both are rehabilitated in Javan Langur Center (JLC). The amplification of Cytochrome-b gene from whole blood DNA with PCR technique using forward primer L151625’­CTTCCATGAGGACAAATATC-3’ and reverse primer Rmuc15’-GTGGAGTATAGGTATGATTGC-3’. The phylogenetic tree reconstruction based on MEGA 5 using maximum likelihood (ML) method and pairwise distance analysis with Kimura-2 parameter model resulted that Andin and Bobby are in the same group with <br />T. a. auratus. Andin is in the same clade with T. a. auratus haplotype aaF, while Bobby in the same clade T. <br />a. auratus and T. a. auratus haplotype aaC. We concluded that both of them belong to T. a. auratus subspecies.</p><p><br /><strong>Keywords</strong>: Javan Langur (Trachypithecus auratus), Javan Langur Center (JLC), Cytochrome-b</p>

A study on feeding behavior of two primate species viz; Phayre’s leaf monkey (Trachypithecus phayrei, Blyth, 1847) and capped langur (Trachypithecus pileatus Blyth, 1843) was conducted during summer season (March–May, 2014) in Dampa Tiger Reserve (DTR), Mizoram, India. Study was carried out in the Terei range of forest reserve. A total of 87 plant species including bamboo were recorded in the area. Both species of primates (T. phayrei and T. pileatus) were studied for their food plant selection, diet composition, time budget for activities during day. Selection of trees to sleep at night was also observed. Capped langur selected 7 food plant species whereas Phayre’s leaf monkey selected 8 food plants. 40% of the plant species were common to both the primate species; however they showed a distinct variation in food plant preference. Phayre’s leaf monkey spent S 90% of feeding time on Musa ornata, Melacana baccifera and Dendrocalamus longispathus and S 80% Musa balbisiana, Gmelina arborea and Buetneria pilosa; an indication of preference for bamboo species and climbers. Capped langur spent feeding time S 90% on Ficus maclellendi and Ficus semicordata while other species were given comparatively less time. Both the species had consumed young leaves, flowers and fruits in their diet that constitute nearly 80% of the diet. Food items were drawn from different plants. The Phayre’s preferred Dendrocalamus longispathus, (98%) as sleeping site while the Capped langur selected Ficus benghalensis (90%) to sleep at night. Both the species are folivorous in nature but the selection of food plants, source of diet components and plants used to sleep at night were different that indicates that both species has distinct niche within the same habitat type; a very strong survival strategy.

Cat Ba langurs (Trachypithecus poliocephalus), endemic to Cat Ba Island (Vietnam), are a member of the limestone langur group (francoisi species-group) found in Laos, Vietnam, and China. With less than 75 individuals in the world, these Cat Ba langurs are Critically Endangered. This dissertation represents the first long-term behavioural study of the species (549 contact hours across 11 months), and provides socioecological information for two groups (n=17-20) living on the Cua Dong fjord, which can be used in conservation management. Like most other colobines, the majority of the Cat Ba langur diet is leaves (84% of their dietary budget). This may explain their activity budget, which is primarily inactivity (55% of their activity budget), followed by foraging (19%) and social behaviour and locomotion (12% each). Activity and dietary budgets vary seasonally, with animals spending more time in social behaviours in the wet season, when they eat more fruit, and more time in foraging in the dry season, when leaves are ingested more, suggesting they are energy maximisers. In addition, age differences were found, with adults spending the most time in social behaviours and resting. Social behaviour primarily includes grooming and playing with others - play is more common in younger animals, while older animals tend to groom more. Overall, they spend 58% of their days not in proximity to any other langurs. Adult males spend the most time alone, and seem to avoid young langurs. Disputes tend to be between adult females, and two females only tend to come together if there is a young langur acting as a ‘social glue’. Home ranges varied between groups with the larger group’s range being 50ha compared to just 22ha for the smaller group. In both areas, rocks and sparsely covered areas are used most often, which is due to the shrubby, discontinuous vegetation. Most of the langurs’ observable time is spent on exposed slopes (47%), followed by steep cliffs (38%), summits (11%), valleys (3%), and the ground (1%); this varied seasonally, likely to balance foraging needs with thermoregulation. The langurs used 22 sleeping sites, including ledges (61%) and caves (17%). When newborn, Cat Ba langurs are bright orange. They start to lose this natal coat as an infant, and become much darker during the young juvenile stage. As individuals age, they also become more independent and start to forage and locomote more on their own. These reported behaviours can be used to create a baseline for activity budgets, home range size, and habitat use, and development and maturation that can be used for comparative purposes in future studies. Results find that animals are behaviourally similar to other related species and their biggest threat is likely their small, fragmented population structure. To combat this, I support habitat protection, patrols, and enforcement; education and training; habitat corridors; and limiting the human population, as these support an entire ecosystem while teaching locals the importance of biodiversity, reducing resource competition, and fragmentation from infrastructure, and providing a means for the langurs themselves to disperse.

Delacour’s langur (Trachypithecus delacouri) is a critically endangered Southeast Asian colobine, found in the karst outcrops of northern Vietnam. Half of the remaining population (estimated at fewer than 200 individuals) resides within Van Long Nature Reserve, Ninh Binh Province. This thesis aims to further the conservation of T. delacouri by reviewing the first release of captive-bred individuals as a potential conservation tool for the species, along with acquiring a greater understanding of the species’ behaviour. Behavioural focal observations were conducted throughout 2011, both on wild groups at Van Long and captive individuals at the Endangered Primate Rescue Center (EPRC) at Cuc Phuong National Park. A group of three individuals was released by the EPRC into Van Long in August 2011 in an aim to connect populations and promote interbreeding, and was tracked using GPS radio collars for a period of up to 13.5 months, with the release then evaluated in line with IUCN reintroduction guidelines. Activity budgets of the wild versus captive T. delacouri populations showed significant differences, although both were in line with typical colobine budgets. Inactivity dominated (wild 75.0%, captive 61.9%), with feeding behaviours also playing a major part (wild 21.3%, captive 29.0%). Sex differences were minimal, but age differences showed that young were more social, and adults spent more time inactive and less time feeding. Both affiliative and antagonistic social interactions were common, with females and young most likely to be involved in affiliative behaviours. Infants showed significant changes in their behaviour as they aged, becoming increasingly social and independent, with allomothering witnessed. Vocalisations were predominantly performed by adult males, with grunts the most common call (61.2%) of the seven identified. An individual’s sex/age class was significantly linked to the type of vocalisation performed. T. delacouri vocalisation behaviour was relatively similar to that of other limestone langurs, although some differences in call structure were found. The released individuals all survived for a minimum of five months before tracking was disrupted for one, showing some wild-like behaviours, although their behaviours were largely atypical. The group quickly separated to travel as individuals, and ranged extensively with the adult male covering 1020ha in 9.5 months. Average day journey lengths were comparable to other limestone langurs (453m–735m), but the individuals did not develop distinct home ranges. A strong diurnal trend in movement showed two peaks at early morning and late afternoon, but minimal seasonal differences were detected. More extensive monitoring is needed to determine whether or not the release was a success, but the project fulfilled an important role as a pilot study to learn how best to conduct a release and how the animals will behave. In reviewing the release it was found to have broadly followed the IUCN guidelines, although gaps were identified suggesting more formalised planning, risk assessments, and consultation was needed. Moving forward, the possibility of translocating existing T. delacouri subpopulations, rather than conducting further captive releases, should be explored as a conservation strategy, along with continuing the effective protection measures in place at Van Long.
