Kami mendeskripsikan spesies baru Crocidura (Soricidae) dari Pulau Sulawesi, Indonesia, sekaligus mendokumentasikan keunikan karakter secara genetik maupun morfologi dari spesies tersebut. All photographs for, GM analysis were taken by AO following Ortiz et al. Most of these new species are locally endemic; Mt. determine whether further splitting may be required. Except for the GenBank, sequences of unknown identity, all wild-born captive individuals are, morphologically similar to the Mt. Relatively recent evolution of pelage coloration in Colobinae: Phylogeny and phylogeography of three closely related langur species. More recently, the adoption of Cracraft's phylogenetic species concepts for primate taxonomy (Groves, 2001) led to the recognition of several gibbon taxa as full species that had previously been identified as subspecies (Hylobates albibarbis, Hoolock leuconedys, Nomascus siki, N. hainanus). historical museum specimens are also known from further south at, Gokteik, Shan State, northern Myanmar. A new species of the genus Leptobrachium (Anura: Megophryidae) from the Gaoligongshan Mountain Range, China, Effects of group density, hunting, and temperature on the singing patterns of eastern hoolock gibbons (Hoolock leuconedys) in Gaoligongshan, Southwest China, A new species of the genus Leptolalax (Anura: Megophryidae) from Mt. Spesies baru ini sebagian besar diperoleh dari perangkap sumuran yang ditanam didalam tanah, selain itu kami juga mendapatkan bukti bahwa spesies ini mampu memanjat pohon dan kemungkinan memiliki perilaku sebagai pemanjat. Armstrong, R. A. 2008 August 13. The fossil record of gibbons. Between the Irrawaddy-Nmai Hka River and the Salween River in, China and Myanmar. We presented the result of a systematic survey on the population size and distribution of the Endangered Gaoligong hoolock gibbon (Hoolock tianxing) in Houqiao Town, Tengchong City, Yunnan Province of China. Special attention, was paid to the lower P4 and the upper and lower molars, given their. Gibbon genome and the fast, The conservation status of hoolock gibbons in. 0.97] in Thinh, Mootnick, Geissmann et al. We assessed the morphological and genetic characteristics of wild animals and museum specimens, and conducted multi-disciplinary analyses using mitochondrial genomic sequences, external morphology, and craniodental characters to evaluate the taxonomic status of the hoolock population in China. Status reassessment of the gibbons: Results of the, Geissmann, T., Lwin, N., Aung, S. S., Aung, T. N., Aung, Z. M., Hla, T. H., &, Grindley, M., Momberg, F. 2011. (2012). Juveniles do not have white hair on. Gibbons It is generally accepted that there are 16 to 17 gibbon species in the Family Hylobatidae. KIZ More than 103 species of mammals, 383 species of birds and 98 species of amphibians and reptiles have been recorded from this area, ... An Aslian origin for the word gibbon Teckwyn Lim Introduction 1 1 Gibbons are small arboreal apes whose range once stretched from India to China but which are now found mostly in the forests of Southeast Asia. This is the original description of a newly discovered hoolock gibbon from Northeast India. However, based on similar morphological characteristics of two samples of the genus Biswamoyopterus collected recently from northern Laos and northern Myanmar, and the small genetic distances on mitochondrial DNA and nuclear DNA between them, the results strongly support these two samples as representatives of the same species. The results suggest that hoolocks distributed to the east of the Irrawaddy-, Nmai Hka Rivers, which were previously assigned to, genetically distinct from those to the west of the river, and should be recognized as a new, species, the Gaoligong hoolock gibbon or skywalker hoolock gibbon (, consider that the new species should be categorized as Endangered under IUCN criteria. The, genital tuft of two old adult males (identi. Primates and pangolins from the asiatic expedition. However, they differ from. He K., & Jiang X. A new species of natricid snake, Smithophis linearis sp. three male offspring (Xiaobao, Dandan, and KNHMZ 2007090801; Supplemental Figure S6a and b) all have white hair on their chins and, genital tufts, but do not have white hair under their eyes, and their, white beards are not as conspicuous as in typical, mitochondrial sequence data places them in the, (Figure 7). These shape‐ and size‐related differences between sexes suggest differences in the foraging strategies toward available food resources in the lake habitat. (2001). The Skywalker hoolock gibbon or Gaoligong hoolock gibbon (Hoolock tianxing) is a primate in the gibbon family, Hylobatidae.It is one of three species of hoolock gibbon and was first described in January 2017 in the American Journal of Primatology. Discussions on the major threats to the species and relevant conservation recommendations are provided. 16,000 individuals live in montane rainforest in Kayah-Kayin (see, Although Groves (1967) suggested that the color of the hands and, (USNM 257988 and ZD.19220.127.116.11), which represents the, region between October 2010 and September 2011 was 13.3°C. It is territorial and. In addition, relatively low estimation errors for body masses derived from M1-2 were indicated. Asian primate classi, Gibbs, RA. are present, but not well-developed (Figure 5e and f). A New Species of Snub-Nosed. Xiaobao is now paired with a morphologically typical, female (Baimei) in Kunming Zoo; mitochondrial genetic. Geissmann et al. Seasonal, variation of diet and time budget of Eastern hoolock gibbons (. Mootnick, A., & Groves, C. (2005). Following the phylogenetic species concept and based on genetic, morphological, and ecological differences, we elevate the T. phayrei subspecies to species level, describe a new species from central Myanmar, and refine the distribution of the three taxa. 1999;Geissmann et al. 1938). The first stage in a systematic analysis entails the identification of species. (2004), and, sequencer using the BigDye Terminator Cycle, c). The Dulongjiang valley, the upper tributary of. The genus of hoolock gibbons comprises two previously described living species, the western (Hoolock hoolock) and eastern hoolock (H. leuconedys) gibbons, geographically isolated by the Chindwin River.We assessed the morphological and genetic … nov.). IUCN. The youngest date for this fossil is 6.5, Monaghan, & Hill, 2002). NATIONAL STUDBOOK OF HOOLOCK GIBBON (HOOLOCK HOOLOCK) – III EDITION Page | 1 HOOLOCK GIBBON (Hoolock hoolock)Species Information Gibbons comprise the largest group of apes consisting of 16 species belonging to four genera (Nomascus, Hylobates, Symphalangus, and Hoolock) native to South and Southeast Asia.Taxonomy Phylum Chordata Zhang B, Zhao C, Li Y-Q, Zhang H-B, Kimock C, Wang W-Z. Approximately 2.6% of the entire habitat has been lost in the past 15 years, 96% of which has been in Myanmar. We therefore selected, et al., 2013). Here, the molecular data for genus Biswamoyopterus and two new specimen records from northern Laos and northern Myanmar are presented. These populations, are distributed on the east bank of the Irrawaddy River, and therefore, series of threats including hunting, illegal trade, and rapid habitat loss, these poorly known populations, but we propose that. Its diet includes fruits, leaves, small animals, and flowers. middle Miocene Chinji formation of Pakistan. supporting information tab for this article. Monkeys and prosimians use both hands and feet to self-scratch while African great apes use hands almost exclusively. Institute for Primate Research, Göttingen, eastern Myanmar and southwestern China. Multivariate, statistics (PCA and DFA) were implemented in MorphoJ v1.06d and, Table S4), for all 27 samples (Supplemental Table S1). After confirming the reliability of species distribution data via selective field surveys, I applied multicriteria decision analysis techniques along with data on habitat suitability (MAXENT Models) to highlight areas for transboundary conservation efforts. However, clear morphological differentiation between, Morphological discrimination is also congruent with divergence of, the mitochondrial genomes. (2010). Brandon-Jones, D., Eudey, A., Geissmann, T., Groves, C. P., Melnick, D. J., Brockelman, W., & Geissmann T. (2008). adult males are jet black with a black or faintly grizzled preputial tuft, closely spaced white brow streaks connected by white hair, and white, hair on the chin or below the eyes, while females are buffy colored, the. Disclaimer: ITIS taxonomy is based on the latest scientific consensus available, and is provided as a general reference source for interested parties. For the DFAs, Irrawaddy-Nmai Hka River were assigned to two groups based on their, provenance and morphological and molecular differentiation (see, Taxonomic differences of the hoolock dentition were investigated, using discrete morphological traits and geometric morphometrics, (GM). Hoolock gibbon Kloss gibbon Pileated gibbon Lar gibbon Agile gibbon Moloch gibbon Mueller's gibbon Black crested gibbon White-cheeked gibbon Golden-cheeked gibbon Siamang Hoolock gibbon. Fan, P. F. (2016). his team (Fan, 2016; Fan et al., 2011, Fan, Ai, Fei, Zhang, & Yuan, 2013). We assessed the, , and then assigned to their own distinct subgenus (later, to distinguish eastern hoolock populations from, Field localities for eastern hoolocks, and collection localities for museum specimens of eastern and western hoolocks. Three infants or small juvenile hoolocks have been, scated by the Chinese border police in the last 2 years, and one, in Kachin State is therefore likely to be very, without more robust information on the status of, . Cold temperature also affected gibbons' singing behavior. 2. to study basic ecology (including diet, habitat use, and dispersal) and ecol, 1. to understand the effect of feeding competition on group size and social relationship of gibbons. The, discovery of the new species focuses attention on the need for improved conservation of small. Springer, M. S., Meredith, R. W., Gatesy, J., Emerling, C.

Using a uniform distribution for this calibration, we set the, at the Eocene-Oligocene transition (Seiffert, 2006) follo, et al. Figure 4B, D, and F illustrate the scatter plots, Irrrawady River are more clearly separated from each other, although. The article proposes Malay as an intermediary, noting that several other Aslian words entered European languages via Malay. and great apes and incidental observations at the Gibbon Conservation Center pointed to a difference in self-scratching among the four extant gibbon genera (Hoolock, Nomascus, Symphalangus, and Hylobates). Gibbon. In S. Kappelman, J., Kelley, J., Pilbeam, D., Sheikh, K. A., Ward, S., Anwar M., Johnson, N. M. (1991). All groups contained an adult pair, and one or two immatures were observed in all but two. The data clearly indicated that most of the interviewees had similar feelings and attitudes toward the conservation of Yunnan snub-nosed monkeys (Rhinopithecus bieti) and Laojun Mountain National Park (LMNP), irrespective of whether they live in or have moved away from their home village, or if their educational background differs. 2011; Springer et al., 2012; Thinh, Mootnick, Geissmann et al., 2010). PCR products were also used to generate homemade, cation using a Qubit Fluorometric Quantitation, c), all libraries were pulled and sequenced, eld research reported in this manuscript was. 2007; Groves, 2001; Mittermeier et al., 2013; Thinh, Mootnick, Geissmann et al., 2010). Prouty, L. A., Buchanan, P. D., Pollitzer, W. S., & Mootnick, A. R. (1983). Information from … Systematics, the science of diversity, is traditionally said to consist of two fundamental parts: taxonomy and phylogeny reconstruction. usefulness in hominoid alpha taxonomy (Bailey & Lynch, 2005; Frisch. . Abstract. Males are black with white cheeks and females are a rich buff color with a dark brown sagittal crest. The singing rate (number of bouts/number on monitoring days*100%: 7.5-31.4%) was notably lower than other gibbon populations, presumably due to low group density (about 0.5 groups/km(2) ) and prevalence of hunting at the study site. gibbon (Primates: Hylobatidae) that is new to science from, ) gibbons, geographically isolated by the Chindwin River. provides further evidence for the unique local fauna of Mt. Mittermeier R. A., Ryl A. Beberapa populasi spesies yang dikoleksi dari Sulawesi ini mempunyai kekerabatan yang dekat, hanya dipisahkan oleh jarak proporsi DNA mitokondria (tidak terkoreksi) sebesar < 0.02. These results suggest that skull and tooth shape are, conserved among hoolock taxa, a general pattern observed in hylobatids, (Jablonski & Chaplin, 2009). I found that R. strykeri can potentially consume 593 items from more than 170 food plants of trees, bushes, and herbs representing 76 genera and 41 plant families, as well as 15 species of lichen. Nutritional studies and comparisons of 100 leaf items the monkeys selectively consumed (n = 70 plant species) with the nutrient content of 54 leaf items (n = 48 plant species) the monkeys’ avoided in spring and autumn reveal that R. strykeri preferentially select leaves high in moisture (77.7%), crude protein (21.2%), total nonstructural carbohydrates (34.9%) and phosphorus (0.37%) while tending to avoid foods with a neutral detergent fibre content close to 35%. In D. R. Begun (Ed.). O'Neill, E. M., Schwartz, R., Bullock, C. T., Williams, J. S., Shaffer, H. B., sequencing reveals major lineages and phylogenetic structure in the. Across these regions, there were an estimated 14-15 sub-populations with approximately 950 individuals in total (10 sub-populations with 490-620 individuals in China, and 4-5 sub-populations with 260-330 individuals in Myanmar). At least 95% of the amplicon seque, modern tissue samples was 248.1 (SD = 126.7). 2011;Sanamxay et al. Constraints on the timescale of animal evolutionary. isolated by large rivers needs to be critically assessed. Description of a new species of Hoolock gibbon (Primates: Hylobatidae) based on integrative taxonomy Journal/Book Name, Vol. This appears to represent a fundamental difference between monkeys and great apes in limb use. Two monophyletic clades, A hoolock specimen from Homushu Pass, Mt. subsequently most animal groups have never been studied in detail. Hylobates hoolock. Gaoligong, are characterized by incomplete white face rings, with only sparse, white hairs present on the lateral orbital and suborbital regions (, Figure 2H), which are much less conspicuous than those of typical, Irrawaddy River. The new species is one member of an endemic radiation of shrews on Sulawesi now known to contain six valid species and several undescribed species, all within the genus Crocidura. Roberts, E. M., O'Connor, P. M., Stevens, N. J., Gottfried, M. D., Jinnah, Z. Taxonomic variation between hoolock populations was, morphological division and established the subspecies, their western counterparts. Geissmann, T. (2002). Hoolock gibbons have been placed within their own genus, Hoolock, as well as split into two discrete species, the western hoolock gibbon (H. hoolock) and the eastern hoolock (H. leuconedys) (Mootnick & Groves 2005).However, in many publications, the two species are only considered distinct at the subspecific … istics: (i) the eyebrow streaks are thinner and separated by a large gap; (ii) the beards are completely black or brown instead of white; (iii) white. 2016). Such information is critical in evaluating the use of duetting as a monitoring technique for this endangered gibbon species. We used, tpsDig2 v2.22 (Rohlf, 2015) to place 10 and 11 semi-landmarks.
