| the impact of fossil calibrations, codon positions and relaxed clocks on the divergence time estimates of the native australian rodents (conilurini). | the native rodents are the most species-rich placental mammal group on the australian continent. fossils of native australian rodents belonging to the group conilurini are known from northern australia at 4.5ma. these fossil assemblages already display a rich diversity of rodents, but the exact timing of their arrival on the australian continent is not yet established. the complete mitochondrial genomes of two native australian rodents, leggadina lakedownensis (lakeland downs mouse) and pseudomy ... | 2010 | 20153409 |
| murine viruses in an island population of introduced house mice and endemic short-tailed mice in western australia. | house mice (mus domesticus) were recently introduced to thevenard island, off the northwest coast of western australia. this island is also habitat for an endangered native rodent, the short-tailed mouse (leggadina lakedownensis). concerns have been raised that house mice may pose a threat to l. lakedownensis both through competition and as a source of infection. to assess the threat to l. lakedownensis posed by viral pathogens from m. domesticus, a serological survey was conducted from 1994 to ... | 1999 | 10231757 |
| water and sodium requirements of field populations of house mice (mus domesticus) and short-tailed mice (leggadina lakedownensis) on thevenard island, in the arid pilbara region of western australia. | the coexistence of the lakeland downs short-tailed mouse leggadina lakedownensis and house mouse mus domesticus on thevenard island, in the arid north of western australia, prompted a study to compare their seasonal water and sodium metabolism using tritiated water and sodium-22 as tracers. fractional water influx rates for m. domesticus (40.3 +/- 1.6% total body-water day-1) were significantly higher than those for l. lakedownensis (25.3 +/- 1.2% total body-water day-1). water effluxes were hig ... | 1999 | 10549142 |
| water and sodium balances and metabolic physiology of house mice (mus domesticus) and short-tailed mice (leggadina lakedownensis) under laboratory conditions. | a laboratory study investigated the metabolic physiology, and response to variable periods of water and sodium supply, of two arid-zone rodents, the house mouse (mus domesticus) and the lakeland downs short-tailed mouse (leggadina lakedownensis) under controlled conditions. fractional water fluxes for m. domesticus (24 +/- 0.8%) were significantly higher than those of l. lakedownensis (17 +/- 0.7%) when provided with food ad libitum. in addition, the amount of water produced by m. domesticus and ... | 1999 | 10633560 |
