Common treeshrew (Tupaia glis, Tupai akar)Scientific classificationKingdom: AnimaliaPhylum: ChordataClass: MammaliaOrder: ScandentiaFamily: TupaiidaeGenus: TupaiaSpecies: T. glis
The common treeshrew (Tupaia glis) is a small mammal in the treeshrew family Tupaiidae, and is native to Thailand, Malaysia, and Indonesia. It has been listed as Least Concern by IUCN as it remains common and displays some adaptability to ongoing habitat lossDescriptionThe common treeshrew is one of the largest among treeshrews. Average body length is between 16 and 21 cm (6.3 and 8.3 in), and average weight is around 190 g, with varying colours of reddish-brown, greyish or black upper parts and whitish belly. Its long, bushy tail is dark greyish-brown and almost reaches the length of the body. The paws are bare with sharp nails, and with a naked patch of skin above its long nose. Both sexes are similar. The animal has a head and body length of 13–21 cm and a tail length of 12–20 cm.[3] The common treeshrew usually has a white, pale stripe on each shoulder.
The two subspecies are T. g. longipes and T. g. salatana, with T. g. longipes being duller in color than T. g. salatana. The underparts of T. g. longipes are dull buff to reddish-buff, and the underside of the tail is greyish. The underparts and underside of the tail are dark reddish in T. g. salatana. Similar species are Tupaia splendidula and Tupaia montana.
Ecology and behaviorCommon treeshrews are active during the day, and forage for food alone or in pairs, mainly on the ground, among shrubs and tree holes. They feed on fruits, seeds, leaves, and insects, especially ants and spiders. They are also reported to catch lizards.They are very agile in climbing both large vertical tree trunks and bushes, and occasionally jump from stems of a young tree to that of another as much as 60 cm (24 in) away. Their climbing is concentrated in lower heights. They frequently scent-mark their territories by chest and anogenital rubbing with a secretion from glands on chest and scrotum. Adult males are more secretory than females and juveniles. In the Bukit Timah Nature Reserve, mean home ranges of adult males were estimated at 10,174 m2 (109,510 sq ft), of adult females at 8,809 m2 (94,820 sq ft), of juvenile males at 7,527 m2 (81,020 sq ft), and of juvenile females at 7,255 m2 (78,090 sq ft), with partial overlaps between male and female ranges varying from 0.4% to 56.8%. Home ranges of adult residents of the same sex overlap to a lesser degree than those of opposite sexes. A male's range may include the ranges of two or three females. A high overlap between ranges of one adult male and one adult female indicates they form a stable pair. Juvenile ranges of either sex adjoin or overlap with ranges of adults, suggesting the juveniles are family members. Individuals of the same sex are involved in aggressive territorial chases.
