Nature, 1954
A COLONY of tree shrews, Tupaia glis (Diard), has been maintained at the University of Malaya for the past nineteen months, specimens having been obtained both from the Federation of Malaya and from Thailand. A total of fifty-five living animals has been received; the colony at the time of writing includes thirteen males and fourteen females.

Maternal behaviour and the effects of stress in tree shrews
Nature, 1974THE tree-shrews (family Tupaiidae), small squirrel-like mammals occurring throughout South-east Asia, are currently classified1 into two subfamilies: Ptilocercinae (nocturnal pen-tailed tree-shrews; genus Ptilocercus) and Tupaiinae (diurnal tree-shrews; genera Tupaia, Anathana, Dendrogale, Lyongale, Urogale). The overall systematic status of the family

The organization of somatosensory area II in tree shrews
Journal of Comparative Neurology, 1981AbstractMicroelectrode multiunit recording methods were used to determine the somatotopic organization of the second somatosensory area, S‐II, in tree shrews. Neurons were activated by light tactile stimuli, and receptive fields were located on the contralateral body surface only.

Ciliogenesis in photoreceptor cells of the tree shrew retina
Anatomy and Embryology, 1997Transmission electron microscopy of the retinal cones from several prenatal, young postnatal and adult tree shrews (Tupaia belangeri) reveals that the centrioles, from which the ciliary precursors of the outer segments grow out, are not transported into a pre-existing inner segment, but are positioned under the apical plasma membrane of cone precursor ...

Most biarmed chromosomes are morphologically distinct. Among the acrocentrics, one pair is outstandingly large. Some small ones have secondary constrictions. One or two pairs of the small acrocentrics may have a short second arm; thus they may be regarded as small subtelocentric.

Establishment of brain ischemia model in tree shrew
Brain Research, 2019Tree shrew, as a kind of small and inexpensive animal between insectivores and primates with the general anatomy being similar to human, could be considered as developed animal model for brain ischemia (BI) study. However, there is no neural behavior scores criterion from tree shrew with BI up to now.To produce BI model of tree shrew, a novel ...

Breast Cancer in a Tree Shrew (Tupaia glis)
Nature, 1966ON May 29, 1965, a female tree shrew—Tupaia glis sordida, according to the system of Lyon1—was found in a late stage of pregnancy on Tioman Island off Malaya. A nodular lesion measuring about 4 mm was present beneath the skin of the right thoracic breast near the nipple. No other lesions were found and there were no large ectoparasites.

Forelimb Morphology of Tree Shrews
2015The chapter includes three subchapters—Skeleton, Joints and Musculature, which describe, respectively, osteology, syndesmology and myology of the shoulder girdle and forelimb in Tupaia belangeri, one of the most generalized members of the order Scandentia.

On the phyletic relationships of the Tree shrews
Mammal Review, 1974ABSTRACTThe Tree shrews (family Tupaiidae) were earlier grouped with the Elephant shrews (family Macroscelididae) in the suborder Menotyphla of the Insectivora. Following a proposal of Carlsson (1922), many workers, and notably Le Gros Clark, have presented evidence that the Tree shrews should be regarded as primitive or basal Primates.

Fossils directly contribute to the construction of phylogenies in two ways. They provide additional samples (usually taxa) which are used in biological comparisons, so far as the completeness of the fossil material warrants, in order to determine morphocline polarity; that is, in forming a hypothesis of primitive and derived character states.
