| energy metabolism in potoroine marsupials. | fasting and fed metabolic rates were measured in three species of potoroine marsupials, the rufous rat-kangaroo (aepyprymnus rufescens), the long-nosed potoroo (potorous tridactylus) and the brush-tailed bettong (bettongia penicillata). there were no significant differences among potoroine species in fasting metabolic rate. the lowest fasting heat production for each species was 11-20% less than the interspecific value of 295 kj.kg-0.75.day-1 for basal metabolism of mature, non-reproductive euth ... | 1992 | 1401340 |
| eimeria spp. (apicomplexa:eimeriidae) parasitic in the rat-kangaroos hypsiprymnodon moschatus, potorous tridactylus, aepyprymnus rufescens and bettongia gaimardi (marsupialia:potoroidae). | | 1988 | 3225116 |
| neural angiostrongylosis in three captive rufous bettongs (aepyprymnus rufescens). | neurological disease attributed to migration of the rat lungworm (angiostrongylus cantonensis), is described in three captive rufous bettongs (aepyprymnus rufescens). clinical signs, including ascending paralysis and multifocal neurological deficits, were similar to those seen in other species. histologically, the severity of meningoencephalomyelitis ranged from mild to moderate. in one animal cerebrospinal fluid contained a high percentage of eosinophils but peripheral blood cell counts were wi ... | 1997 | 9293336 |

| demography in relation to population density in two herbivorous marsupials: testing for source-sink dynamics versus independent regulation of population size. | we compared demography of populations along gradients of population density in two medium-sized herbivorous marsupials, the common brushtail possum trichosurus vulpecula and the rufous bettong aepyprymnus rufescens, to test for net dispersal from high density populations (acting as sources) to low density populations (sinks). in both species, population density was positively related to soil fertility, and variation in soil fertility produced large differences in population density of contiguous ... | 2005 | 15583939 |
| reversal and convergence in marsupial chromosome evolution. | the karyotypes of marsupial species are characterized by their relatively low number of chromosomes, and their conservation. most species have diploid numbers lying between the two modes, 2n = 14 and 2n = 22, but the karyotype of aepyprymnus rufescens is exceptional in containing 2n = 32 chromosomes. many differences in diploid number between marsupial species can be accounted for by particular fissions and fusions, which are easy to detect because of the low numbers of chromosomes in each karyo ... | 2003 | 14970718 |

| functional morphology of the hindleg in two kangaroos macropus giganteus and aepyprymnus rufescens. | in this study the structures in the hindleg of the kangaroo which are potentially available for jumping were examined. specimens of two species, macropus giganteus and aepyprymnus rufescens, were examined and are described and compared. the basic pattern of the jump of the two species is similar. this is reflected anatomically by the fact that in both species the extensors of the hip, knee and ankle as a percentage of the total weight of the hindleg are greater than the flexors of the same joint ... | 1991 | 2059557 |
| relationships between plasma composition and parotid salivary composition and secretion rates in the potoroine marsupials, aepyprymnus rufescens and potorous tridactylus. | parotid salivation was investigated in two species of potoroine marsupial, aepyprymnus rufescens and potorous tridactylus to ascertain flow rates and composition, the buffer capacity of the saliva with respect to possible dependence of these animals on foregut fermentation, and the similarity of anion excretion patterns to those of the kangaroo parotid. under anaesthesia neither species secreted spontaneously and secretion was stimulated by intravenous infusion of carbachol, bethanechol and isop ... | 1992 | 1281847 |
| ultrastructure and motility of spermatozoa in macropodid and potoroidid marsupials. | in order to gain some understanding of the significance of the morphological features of spermatozoa within the macropodoidea, the motility of spermatozoa from two macropodids (petrogale xanthopus and dendrolagus matschiei) and the motility, number and distribution of spermatozoa from three potoroidids (aepyprymnus rufescens, bettongia penicillata and potorous tridactylus) were examined. sperm were collected by electro-ejaculation or from the cauda epididymides. epididymides from the potoroidids ... | 1995 | 8848581 |
| molecular phylogenetic relationships of two extinct potoroid marsupials, potorous platyops and caloprymnus campestris (potoroinae: marsupialia). | complete 12s rrna and partial cytochrome b (cytb) gene sequences have been obtained from museum samples of two recently extinct potoroids-potorous platyops and caloprymnus campestris. phylogenetic analyses based on these mitochondrial dna sequences suggest that the broad-faced potoroo (p. platyops) was a close relative of the recently discovered potorous longipes and the recently re-discovered potorous gilberti. although the extinct desert rat-kangaroo (c. campestris) was clearly resolved as a m ... | 2004 | 15062789 |
| bacteriophages from the forestomachs of australian marsupials. | bacteriophages were observed in forestomach contents from three species of australian macropodoid marsupials possessing a foregut fermentative digestion: the eastern grey kangaroo (macropus giganteus), the eastern wallaroo (macropus robustus robustus), and the rufous bettong (aepyprymnus rufescens). forty-six morphologically distinct phage types, representing the families myoviridae, siphoviridae, and podoviridae, were identified. the range of forms varied between host species. the greatest dive ... | 1991 | 1785938 |
