| evolution of alanine:glyoxylate aminotransferase 1 peroxisomal and mitochondrial targeting. a survey of its subcellular distribution in the livers of various representatives of the classes mammalia, aves and amphibia. | as part of a wider study on the molecular evolution of alanine:glyoxylate aminotransferase 1 (agt1) intracellular compartmentalization, we have determined the subcellular distribution of immunoreactive agt1, using postembedding protein a-gold immunoelectron microscopy, in the livers of various members of the classes mammalia, aves, and amphibia. as far as organellar distribution is concerned, three categories could be distinguished. in members of the first category (type i), all, or nearly all, ... | 1994 | 7813517 |
| cryptococcosis in tree shrews (tupaia tana and tupaia minor) and elephant shrews (macroscelides proboscides). | fungal infections due to cryptococcus neoformans occurred in seven short-eared elephant shrews (macroscelides proboscides), six large tree shrews (tupaia tana), and five lesser tree shrews (tupaia minor) at the national zoological park during a 30-mo period in 1991-1993. clinical signs were absent or included weight loss, shivering, dyspnea, and/or neurologic disease. definitive antemortem diagnostic techniques included tracheal lavage and serum cryptococcal antigen latex agglutination titers. t ... | 1997 | 9279407 |
| [three new species of the genus medwayella traub, 1972 (insecta: siphonaptera: pygiopsyllidae) from sabah (eastern malaysia, borneo)]. | medwayella traubiana n. sp., m. pfeifferi n. sp. and m. sabahae n. sp. (pygiopsyllidae) are described from sabah (north of borneo island), the first two on tupaia tana (scandentia), the last on sundasciurus lowii (rodentia). sex male is only identified, because these fleas have been collected in sympatry, or even in syntopy. their determination is based on segment ix and aedeagus. if m. traubiana and m. pfeifferi are related to some known species, m. sabahae is clearly distinct from other medway ... | 2004 | 15638138 |
| networks, trees, and treeshrews: assessing support and identifying conflict with multiple loci and a problematic root. | multiple unlinked genetic loci often provide a more comprehensive picture of evolutionary history than any single gene can, but analyzing multigene data presents particular challenges. differing rates and patterns of nucleotide substitution, combined with the limited information available in any data set, can make it difficult to specify a model of evolution. in addition, conflict among loci can be the result of real differences in evolutionary process or of stochastic variance and errors in rec ... | 2009 | 20525582 |
| osteometrical skull character in the four species of tree shrew. | 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 principa ... | 2000 | 10852401 |
| female-biased dispersal and gene flow in a behaviorally monogamous mammal, the large treeshrew (tupaia tana). | female-biased dispersal (fbd) is predicted to occur in monogamous species due to local resource competition among females, but evidence for this association in mammals is scarce. the predicted relationship between fbd and monogamy may also be too simplistic, given that many pair-living mammals exhibit substantial extra-pair paternity. | 2008 | 18797506 |

| staying hot to fight the heat-high body temperatures accompany a diurnal endothermic lifestyle in the tropics. | much of our knowledge of the thermoregulation of endotherms has been obtained from species inhabiting cold and temperate climates, our knowledge of the thermoregulatory physiology of tropical endotherms is scarce. we studied the thermoregulatory physiology of a small, tropical mammal, the large treeshrew (tupaia tana, order scandentia) by recording the body temperatures of free-ranging individuals, and by measuring the resting metabolic rates of wild individuals held temporarily in captivity. th ... | 2018 | 29623412 |
