Aim This research aimed to use a consensus process to develop a framework and definition for nutrition and dietetic research, and to identify dietetic research priorities for Australia for the period 2020 to 2030. Methods A three‐round Delphi process was selected to enable dietitians with demonstrated research expertise to contribute to the national priority development. All Fellows of the Dietitians Association of Australia, Advanced Accredited Practising Dietitians and research leaders were invited to participate (n = 84). The questionnaire was distributed electronically using a 7‐point Likert scale. Rounds 1 and 2 asked participants to comment on the proposed research framework, …

When people first arrived in what is now Queensland, they would have found the land inhabited by massive animals including goannas six metres long and kangaroos twice as tall as a human. We have studied fossil bones of these animals for the past decade. Our findings, published today in Nature Communications, shed new light on the mystery of what drove these ancient megafauna to extinction.

Trees marked by Aboriginal cultural practices are a distinctive part of the Australian landscape. A recent discovery on Wiradjuri country in New South Wales shows some of these “culturally modified trees” may be much younger than anybody thought...

Australia's bushfire crisis has been unprecedented, so it demands an unprecedented national response. Never before has such a large area been burnt by multiple fires in a single fire season, including bushland in Queensland, New South Wales, Victoria, South Australia, Western Australia and Tasmania.

Airborne particulate matter (PM) is a major health risk in urban settings. Ammonia (NH3) from vehicle exhaust is an under-recognised ingredient in the formation of inorganic PM and there remains a shortage of data to properly quantify the role of NH3 from vehicles in PM formation. An Open-path Fourier transform infra-red (OP-FTIR) spectrometer measured atmospheric NH3, carbon monoxide (CO) and carbon dioxide (CO2) at high temporal resolution (5 min) in Western Sydney over 11 months. The oxides of nitrogen (NO2 and NO; NOx) and sulphur dioxide (SO2) were measured at an adjacent air quality monitoring station. NH3 levels were maxima …

Urbanisation largely consists of removing native vegetation. Plants that remain interact with air quality in complex ways. Pollutants can be detrimental to plant growth; plants sometimes reduce air quality, yet some species also improve it through phytoremediation. A common pollutant of concern to human health in urban areas is particulate matter (PM), small particles of solid or liquid. Our study compared roadside moss turfs with leaves of a common Australian tree species, Pittosporum undulatum, in their ability to capture PM along an urban gradient. We sampled nine sites, three in each of three levels of urbanisation: low, medium, and high …

In this study, we present ground-based measurements of column-averaged dry-air mole fractions (DMFs) of CO2 (or XCO2) taken in a semiarid region of Australia with an EM27/SUN portable spectrometer equipped with an automated clamshell cover. We compared these measurements to space-based XCO2 retrievals from the Greenhouse Gases Observing Satellite (GOSAT). Side-by-side measurements of EM27/SUN with the Total Carbon Column Observing Network (TCCON) instrument at the University of Wollongong were conducted in 2015-2016 to derive an XCO2 scaling factor of 0.9954 relative to TCCON. Although we found a slight drift of 0.13 % over 3 months in the calibration curve of …

Static and dynamic flood models differ substantially in their complexity and their ability to represent environmental processes such as storm tide or riverine flooding. This study analysed spatial differences in flood extent between static (bathtub) and dynamic flood models (Delft3D) in estuarine environments with different morphology and hydrodynamics in order to investigate which approach is most suitable to map flooding due to storm surges and river discharge in estuarine environments. Time series of observed water levels and river discharge measurements were used to force model boundaries. Observational data, such as tidal gauge and water level logger measurements, satellite imagery and …

Quantitative understanding of the sources and sinks of greenhouse gases is essential for predicting greenhouse-gas-climate feedback processes and their impacts on climate variability and change. Australia plays a significant role in driving variability in global carbon cycling, but the budgets of carbon gases in Australia remain highly uncertain. Here, shipborne Fourier transform infrared spectrometer measurements collected around Australia are used together with a global chemical transport model (GEOS-Chem) to analyse the variability of three direct and indirect carbon greenhouse gases: carbon dioxide (CO2), methane (CH4) and carbon monoxide (CO). Using these measurements, we provide an updated distribution of these gases. …

While health benefits of legume consumption are well documented, intake is well below recommendations in many Western cultures, and little is known regarding culinary use and consumer understanding of these foods. This study aimed to investigate consumption, knowledge, attitudes, and culinary use of legumes in a convenience sample of Australians. An online computer-based survey was used to gather data and demographic characteristics. Respondents (505 individuals answered in full or in part) were regular consumers of legumes (177/376 consumed legumes 2-4 times weekly). Chickpeas, green peas, and kidney beans were most often consumed, and were made into most commonly Mexican, then …

Geography plays an important role in the distribution of plants on islands. This is in part because of the diversity of places and associated environmental conditions in which the islands are located, but also because of how islands are positioned with respect to one another. This relative positioning enters explicitly into island biogeographical character and can be expressed through spatial models. Over the past 20 years, spatial techniques for the empirical analysis of biological datasets have been increasingly applied to investigate biogeographical phenomena, particularly toward a better understanding of spatially structured underlying causative factors. These might include dispersal and competition, …

Coastlines are dynamic environments, with their Eco-geomorphology controlled by a complex range of natural and anthropic processes. Estuarine environments and associated wetland ecosystems are a critical shoreline types with regards to biodiversity, and are particularly susceptible to the influence of sea-level rise. This project applied future sea-level rise of Intergovernmental Panel on Climate Change (IPCC) hydro-scenarios to assess its impact on the eco-geomorphic aspects of coastal ecosystems in terms of risk assessment and sustainability. Comerong Island is used as a case study and is compared with other surrounding ocean-influenced and lagoonal deltas to assess the regional effects of sea-level rise. …

There is a growing expectation that volunteers will have a greater role in disaster management in the future compared to the past. This is driven largely by a growing focus on building resilience to disasters. At the same time, the wider landscape of volunteering is fundamentally changing in the twenty-first century. This paper considers implications of this changing landscape for the resilience agenda in disaster management, with a focus on Australia. It first reviews major forces and trends impacting on disaster volunteering, highlighting four key developments: the growth of more diverse and episodic volunteering styles, the impact of new communications …

We describe the stratigraphy and chronology of Kudjal Yolgah Cave in south-western Australia, a late Quaternary deposit pre- and post-dating regional human arrival and preserving fossils of extinct and extant fauna. Single-grain optically stimulated luminescence (OSL) dating shows that seven superposed units were deposited over the past 80 ka. Remains of 16 mammal species have been found at the site, all of them represented in Unit 7, for which seven OSL ages indicate accumulation between 80 and 41 ka. Single-grain OSL equivalent dose distribution patterns show no evidence of reworking of older or younger sediments into Unit 7, but late …
