Late Quaternary variability in sediment residence time and provenance in the Gulf of Carpentaria, northern Australia Open
Uranium (U) isotopes in detrital marine sediments provide a means to estimate sediment residence time—the duration particles spend in the landscape prior to deposition. When paired with physical parameters such as specific surface area, th…

Cannabidiol modulates brain copper homeostasis in wild-type-like but not Alzheimer’s disease transgenic female mice: Implications for neuroprotective therapy Open
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterised by cognitive decline, synaptic dysfunction, and neuroinflammation. Disrupted metal homeostasis—particularly involving copper (Cu), zinc (Zn), and iron (Fe)—…

Strontium isoscapes for provenance, mobility and migration: the way forward Open
Strontium isotopes ( 87 Sr/ 86 Sr) are increasingly used as a provenance tool in multiple disciplines. Application to biological materials requires knowledge of the variation in bioavailable 87 Sr/ 86 Sr across the landscape, potentially i…

Megafauna mobility: Assessing the foraging range of an extinct macropodid from central eastern Queensland, Australia Open
Understanding the factors that influence the geographic range of extinct megafaunal species is crucial for reconstructing their ecology and extinction dynamics. For extant herbivores, it has been demonstrated that large body mass provides …

A strontium isoscape of southwestern Australia and progress toward a national strontium isoscape Open
Strontium isotopes (87Sr/86Sr) are widely used tracers in the geosciences. Here we exploit an opportunity to determine 87Sr/86Sr ratios on archived fluvial sediment samples from the low-density National Geochemical Survey of Australia (NGS…

Using Fourier Transform Infrared spectroscopy to produce high-resolution centennial records of past high-intensity fires from organic-rich sediment deposits Open
Background Current observational or instrumental records of past fires are historically limited, and information on fire characteristics tends to be confined to the recent past. Aims and methods Here, we reconstruct a record of high-intens…

Atmospheric particulates over the northwestern Pacific during the late Holocene: Volcanism, dust, and human perturbation Open
Mineral aerosols form a key component of Earth’s dynamic biogeochemical systems, yet their composition and mass are variable in time. We reconstruct patterns in mineral aerosol flux from East Asia, the second largest global dust source, in…

Assessing changes in high-intensity fire events in south-eastern Australia using Fourier Transform Infra-red (FITR) spectroscopy Open
Background As fire regimes continue to evolve in response to climate change, understanding how fire characteristics have responded to changes in the recent past is vital to inform predictions of future fire events. Aims and methods Using F…
