THE IUCN RED LIST OF THREATENED SPECIES™ Taxonomy Kingdom Phylum Class Order Family Animalia Chordata Mammalia Scandentia Tupaiidae Taxon Name: Tupaia discolor (Lyon, 1906) Common Name(s): • English: Bangkan Treeshrew Taxonomic Source(s): Sargis, E.J., Woodman, N., Reese, A.T. and Olson, L.E. 2013b. Using hand proportions to test taxonomic boundaries within the Tupaia glis species complex (Scandentia, Tupaiidae). Journal of Mammalogy 94: 183–201. Taxonomic Notes: Described as Tupaia discolor Lyon, 1906, from Bangka Island off the east coast of Sumatra. The taxon was later synonymised with T. glis by Chasen (1940), and it has generally been considered a synonym of that species (Corbet and Hill 1992, Helgen 2005, Honacki et al. 1982, Wilson 1993). It has been recently resurrected as T. discolor from Bangka Island (Sargis et al. 2013). Assessment Information Red List Category & Criteria: Data Deficient ver 3.1 Year Published: 2019 Date Assessed: June 9, 2017 Justification: This species is listed as Data Deficient, in view of the lack of information about its population, habitat requirements and the threats it faces on Bangka. Geographic Range Range Description: This species is found on Bangka Island off the east coast of Sumatra, Indonesia (Sargis et al. 2013). Country Occurrence: Native: Indonesia © The IUCN Red List of Threatened Species: Tupaia discolor – published in 2019. 1 http://dx.doi.org/10.2305/IUCN.UK.2019-1.RLTS.T111873499A111873502.en Distribution Map Tupaia discolor © The IUCN Red List of Threatened Species: Tupaia discolor – published in 2019. 2 http://dx.doi.org/10.2305/IUCN.UK.2019-1.RLTS.T111873499A111873502.en Population There is no information about the population of this species. Current Population Trend: Unknown Habitat and Ecology (see Appendix for additional information) There is no information about the habitat requirements and ecology of this species, however, the description of T. glis with which it was previously synoymised said that it was usually found in primary dipterocarp forest, thought tolerant to some degree of habitat modification, as it was recorded from secondary forest, plantations, fruit orchards and trees near housing areas (K. H. Han pers. comm. 2008). Systems: Terrestrial Threats (see Appendix for additional information) Extensive tin mining on Bangka Island has caused habitat disturbance, damage to natural drainage, and pollution (Nurtjahya et al. 2009). When this species was previously synonymised with T. glis the major threats to T. glis were listed as severe deforestation due to conversion for agriculture and plantations, and commercial logging, although the species can adapt to a degree of habitat modification. Conservation Actions It is not found in any protected areas. Credits Assessor(s): Sargis, E., Kennerley, R.

Correspondence to: I. Ruf ([email protected]) Received: 17 June 2015 – Revised: 6 September 2015 – Accepted: 7 September 2015 – Published: 25 September 2015 Abstract. The ethmoidal region of the skull houses one of the most important sense organs of mammals, the sense of smell. Investigation of the ontogeny and comparative anatomy of internal nasal structures of the macros- matic order Scandentia is a significant contribution to the understanding of the morphotype of Scandentia with potential implications for our understanding of the primate nasal morphological pattern. For the first time peri- natal and adult stages of Ptilocercus lowii and selected Tupaia species were investigated by serial histological sections and high-resolution computed tomography (µCT), respectively. Scandentia show a very common olfac- tory turbinal pattern of small mammals in having two frontoturbinals, three ethmoturbinals, and one interturbinal between the first and second ethmoturbinal. This indicates a moderately developed sense of smell (moderately macrosmatic).

Skull size and shape were examined among 14 species of the tree shrews (Tupaia montana, T. picta, T. splendidula, T. mulleri, T. longipes, T. glis, T. javanica, T. minor, T. gracilis, T. dorsalis, T. tana, Dendrogale melanura, D. murina, and Ptilocercus lowii). The bones of face were rostro-caudally longer in T. tana and T. dorsalis, contrasting with T. minor and T. gracilis, D. melanura, D. murina and P. lowii which have smaller facial length ratios. The arbo-terrestrial species (T. longipes and T. glis) were similar to terrestrial spe- cies in length ratios of bones of face unlike the other arbo-terrestrial species (T. montana, T. picta, T. splendidula, and T. mulleri).

This article aims to report basic information on the ecology and behaviour as well as a preliminary population assessment of this species on Great Nicobar Island. Nicobar treeshrews spend more than 60% of the day foraging, followed by resting or sleeping (12%). The proportion of time spent on major activities was significantly different across different time periods, with much of the feeding activity in the mornings and evenings. Nicobar treeshrews were observed largely solitarily or as breeding pairs. Observations on mating, aggression and vocalisation are also reported. Most of the ecological and behavioural traits are shared with one or more species of Tupaia in the region.

The morphological and behavioral characteristics of the group have been extensively characterized, and despite previously being classified as primates, recent studies have placed the group in its own family, the Tupaiidae. Genomic analysis has revealed that the genus Tupaia is closer to humans than it is to rodents. In addition, tupaias are susceptible to hepatitis B virus and hepatitis C virus. The only other experimental animal that has been demonstrated to be sensitive to both of these viruses is the chimpanzee, but restrictions on animal testing have meant that experiments using chimpanzees have become almost impossible. Consequently, the development of the tupaia for use as an animal infection model could become a powerful tool for hepatitis virus research and in preclinical studies on drug development. Key words: genome, HBV, HCV, Tupaia, virus Taxonomic Classification related based on brain anatomy [20]. However, recent molecular studies have separated tupaias from the pri- Tupaia belangeri belongs to the family Tupaiidae, mates and placed them in the order Scandentia and which consists of four genera and 19 extant species within the grandorder Euarchonta, which also contains (Table 1) [13, 19].

The skull size and shape were osteometrically examined in the four species of the tree shrews (Tupaia tana, T. javanica, T. minor and T. dorsalis). We suggest that the skull characters were affected by the species specific behavior and terrestrial, arbo-terrestrial and arboreal life, among the genus Tupaia. The neurocranium was laterally narrower in the braincase area, and the splanchnocranium was longer only on dorsal side in T. tana, and these characters were opposite to T. minor. The principal component analysis confirmed the obviously separated clusters among T. tana, T. javanica and T. minor, affected by the adaptation for each behavior. T. dorsalis was considered as terrestrial species from the results of proportion analysis and the principal component analysis.—KEY WORDS: skull, Tupaia dorsalis, Tupaia javanica, Tupaia minor, Tupaia tana.
