Landscape features have been shown to strongly influence dispersal and, consequently, the genetic population structure of organisms. Studies quantifying the effect of landscape features on gene flow of large mammals with high dispersal capabilities are rare and have mainly been focused at large geographical scales. In this study, we assessed the influence(More)
Impacts of individual personality on group distribution were investigated using sheep (Ovis aries) as a model. In an indoor exploration test, individuals who visited <4 (out of 6) objects in a novel environment were classified as 'shy' (n=10), and those who visited 5 or 6 objects were classified as 'bold' (n=10). Nine weeks later, using a series of groups(More)
To date, there has been scant information about the burden of methicillin-resistant Staphylococcus aureus infections in Central Australia. Our aims were to determine the proportion of Staphylococcus aureus infections due to methicillin-resistant strains in Central Australia, to characterise resistance to non-beta lactam antibiotics and to correlate findings(More)
A clutch of young chicks housed with a mother hen exhibit ultradian (within day) rhythms of activity corresponding to the brooding cycle of the hen. In the present study clear evidence was found of ultradian activity rhythms in newly hatched domestic chicks housed in groups larger than natural clutch size without a mother hen or any other obvious external(More)
In recent years, the development of satellite altimetry has opened previously unexplored regions of the world's oceans to exploration by marine geoscientists. By correlating sea surface gravity with seafloor depth, researchers gain insight into the kinematics of seafloor spreading and the physical mechanisms by which the seafloor is formed and deformed.(More)
BACKGROUND The Central Australian Indigenous population has a high incidence of Staphylococcus aureus bacteremia (SAB) but little is known about the local molecular epidemiology. METHODS Prospective observational study of bacteremic and nasal colonizing S.aureus isolates between June 2006 to June 2010. All isolates underwent single nucleotide polymorphism(More)
The availability of reliable assays for measuring 4β-hydroxycholesterol (4β-HC), a CYP3A metabolite of cholesterol, is an important step in qualifying this endogenous moiety as a biomarker of CYP3A activity. Liquid and gas chromatographic methods with mass spectrometric detection have been developed with varying sensitivities, with or without(More)
Opioid-induced respiratory depression (OIRD) is a serious and potentially life-threatening complication of opioid overdose, abuse, and misuse. An option to avert OIRD is to treat patients on strong opioids with respiratory stimulants that do not interact with the opioid system and consequently do not compromise opioid analgesic efficacy. The BK-channel(More)
