Frequent or freakish? Framing bushfires in the context of climate change
… thesis explores media coverage of catastrophic bushfires in Australia across three large-circulation newspapers. It compares the ‘Black Saturday’ bushfires of February 2009 and the ‘Black Summer’ bushfire disaster of 2019-20 to discover how fire is framed within Australian newspaper outlets, and …

Quantitative Geographic Analysis: A Cultural History of Australian Bushfire Narratives
… serialised fiction and journalistic accounts of bushfires side by side. Across the 19th century, fictional depictions of settler endurance and survival were increasingly tempered by journalistic portrayals of destruction. By the century's end, these narratives framed fire as a force that overcame …

Visualising convective heat transfer in a propagating wildland fire
Bushfires are a large destructive natural hazard, intensified by climate change and increasing human activity into wildland areas. Accurate prediction of fire behaviour is essential for mitigation strategies and emergency response. While radiative heat transfer has traditionally been emphasized in …

Spatial and temporal patterns (1973-2012) of bushfire in an arid to semi-arid region of Western Australia
… between the Murchison and Minilya Rivers, of all bushfires greater than 1 ha that were visible from Landsat satellite imagery ranging from 30 – 60m ground resolution. The data was analysed to characterise a general bushfire regime for the region which included: mean and median size of fire scars; …

Reducing future bushfire risk : optimal strategies for fuel load reduction
Bushfires are among the most destructive natural hazards, threatening ecosystems, public health, and infrastructure. As risks intensify due to climate change, urban expansion, and land-use change, there is an urgent need for integrated and sustainable management approaches. In this study, we …

Chemical composition and toxicity of emissions from burning five vegetation types of Western Australia under experimental combustion conditions
… impact on human health of particulate from bushfires and emphasise the importance of vegetation type on toxicological outcomes of bushfire-derived PM2.5. The EFs obtained in this study can be used in models to estimate the emissions from bushfires in Australia, particularly Western …

Takotsubo Syndrome: Precipitants, Clinical Course and Emerging Treatments
… temperatures, pollution, and proximity to bushfires(as individual and cumulative stressors) with the incidence of ACS and TTS. We also investigated the impacts of exogenous catecholamines and catecholamine-potentiating drugs(CPD) on TTS. In regards to the impacts of variable severity of …

The conservation status and dynamics of a protected African lion Panthera leo population in Kafue National Park, Zambia
… hunting of lions and frequent, uncontrolled bushfires). I provide both direct and indirect evidence of such threats, and conclude that lion abundance in Kafue is limited primarily by the suppressed prey population, while the extent and regularity of bushfires may also have adverse effects. I …

Application of multiple unmanned aircraft systems (UAS) for bushfire mitigation
… decision making phases. Currently in the case of bushfires disaster response services rely on watchtowers, manned aircraft and satellite data for information. Advances in technology such as the development of sense-and-avoid systems will soon allow Unmanned Aircraft Systems (UAS) to be flown …

Surgery and Climate Change: The Scientific and Public Policy Implications
… arising from severe weather events, including bushfires, floods, winds and superstorms. Indirect effects may involve injuries arising from the flow-on effects of heat, such as a possible increase in violent activities (known in the literature as the “heat hypothesis”), as well as effects …

An exploration of the emotional network in donation activity in local crisis scenarios
… of disasters increase globally, including bushfires and floods in Australia, donations have become pivotal to short-term relief and early recovery. While existing research predominantly conceptualises donations as financially or motivationally driven transactions, this study reframes …
