Range dynamics and demographics of spatially structured populations under global change. Why are particular species present in some locations, but not others? This is a simple, fundamental ecological question, yet surprisingly, our answers on this point remain far from complete. Using an integrated, systems-based approach, we will determine the interplay between: (i) birth, death and movement rates, (ii) species interactions, and (iii) the constraints of the physical environment (temperature, ra ....Range dynamics and demographics of spatially structured populations under global change. Why are particular species present in some locations, but not others? This is a simple, fundamental ecological question, yet surprisingly, our answers on this point remain far from complete. Using an integrated, systems-based approach, we will determine the interplay between: (i) birth, death and movement rates, (ii) species interactions, and (iii) the constraints of the physical environment (temperature, rainfall, soil type), which determine the limits of species' ranges. Our models will provide Australian conservation managers with a novel, validated toolbox to explore the trade-offs, and synergies, inherent in trying to adapt to climate change and other stressors on biodiversity.Read moreRead less
Ecosystem level impacts of climate change on a temperate grassland. The sustainable use of temperate native pastures is important economically because of grazing and for biodiversity since they are home to many threatened plants. Native pasture sustainability depends on maintaining species diversity and vegetation productivity, both of which have been shown to change in response to climate change. The aims of this project are to elucidate what impact these changes have on the ecosystem propertie ....Ecosystem level impacts of climate change on a temperate grassland. The sustainable use of temperate native pastures is important economically because of grazing and for biodiversity since they are home to many threatened plants. Native pasture sustainability depends on maintaining species diversity and vegetation productivity, both of which have been shown to change in response to climate change. The aims of this project are to elucidate what impact these changes have on the ecosystem properties of a native pasture. This is important, as it will allow likely problems caused by global climate change to be predicted by increasing the understanding of the underlying mechanisms as well as improving the management of grasslands in an environmentally sustainable way.

How does warming prevent soil nitrogen availability from declining in response to elevated CO2? The sustainable use of the terrestrial environment depends upon maintaining ecosystem productivity which in turn depends upon nutrient availability within the soil. Increasing levels of CO2 in the atmosphere are known to decrease nutrient availability while warming prevents this from happening. The aims of this project are to determine how warming is able to prevent elevated CO2 concentrations from re ....How does warming prevent soil nitrogen availability from declining in response to elevated CO2? The sustainable use of the terrestrial environment depends upon maintaining ecosystem productivity which in turn depends upon nutrient availability within the soil. Increasing levels of CO2 in the atmosphere are known to decrease nutrient availability while warming prevents this from happening. The aims of this project are to determine how warming is able to prevent elevated CO2 concentrations from reducing soil N availability and hence productivity in a native grassland ecosystems. This is important, as it will allow likely problems caused by global climate change to be predicted by increasing the understanding of the underlying mechanisms as well as improving the management of grasslands in an environmentally sustainable way.

A study of travel writing in Australian colonial history. Travel writing is a key mechanism by which readers learn about other peoples and cultures, a genre that is crucial to the formation of identities, ideologies, and ideas. Australian travel writing provided foundational texts for those emigrating to the colony. This project positions Australian texts within an international comparative sphere. It will advance the understanding of colonial culture in Australia, and of the perceptions and val ....A study of travel writing in Australian colonial history. Travel writing is a key mechanism by which readers learn about other peoples and cultures, a genre that is crucial to the formation of identities, ideologies, and ideas. Australian travel writing provided foundational texts for those emigrating to the colony. This project positions Australian texts within an international comparative sphere. It will advance the understanding of colonial culture in Australia, and of the perceptions and values of those who settled colonial Australia. It will make available to Australian and international students and researchers a rich archive of texts that have not been previously mapped. Australians are keenly interested in travel and its literature, and this project brings colonial travel texts to public attention.Read moreRead less
Travelling Home: A Study of Walkabout, Australia's Geographic Magazine (1934-74). Walkabout was one of mid-twentieth century's most popular magazines with a focus on inland Australia, as well as the Pacific region. It graced suburban lounge rooms, doctors' and dentists' surgeries, railway waiting rooms, ministerial offices, and school libraries. Walkabout's mixture of entertainment and education ensured its influence across a spectrum of readers: across age, class, and educational boundaries.

Walkabout was one of mid-twentieth century's most popular magazines with a focus on inland Australia, as well as the Pacific region. It graced suburban lounge rooms, doctors' and dentists' surgeries, railway waiting rooms, ministerial offices, and school libraries. Walkabout's mixture of entertainment and education ensured its influence across a spectrum of readers: across age, class, and educational boundaries. This project explores the role of Walkabout in the development of a modern national identity. Walkabout deliberately cultivated one of Australia's key modern economic foundations-the travel industry-and did so whilst also influencing knowledge formation and circulation. Read moreRead less
Impacts of climate change on sustainability of temperate native pasture: an experiment. The sustainable use of temperate native pastures is important economically because of grazing and for biodiversity since they are home to many threatened plants.

The sustainable use of temperate native pastures is important economically because of grazing and for biodiversity since they are home to many threatened plants. Native pasture sustainability depends on maintaining species diversity and vegetation productivity. Climate change is likely to have major impacts on both factors. The aims of this project are to elucidate the impacts of climate change on the species composition, productivity and nutritional quality of a grazed native pasture. This is important, as it will allow us to predict likely problems caused by global climate change and increase our understanding of the mechanisms underlying these changes.Read moreRead less
Creatures of the Ice: A Cultural Analysis of Human-Animal Relations in Antarctica. Perceptions of animals in the world's largest wilderness, Antarctica, have changed dramatically over history: once seen primarily as commercial resources, whales, seals and penguins are now environmental icons. As few people ever travel to Antarctica, their views of its animals are usually dependent on written and visual texts. Combining expertise in the humanities and sciences, this project examines the ways in w ....Creatures of the Ice: A Cultural Analysis of Human-Animal Relations in Antarctica. Perceptions of animals in the world's largest wilderness, Antarctica, have changed dramatically over history: once seen primarily as commercial resources, whales, seals and penguins are now environmental icons. As few people ever travel to Antarctica, their views of its animals are usually dependent on written and visual texts. Combining expertise in the humanities and sciences, this project examines the ways in which humans have narrated their encounters with animals in Antarctica over the last two centuries. Australia is custodian of forty-two percent of Antarctica; this project provides a cultural context through which to understand current attitudes towards its fragile ecosystems.Read moreRead less
Reconstructing past population dynamics to understand human and climatic impacts in prehistory. More than 100 species have become extinct since humans first colonised Australia, and over 1000 are considered threatened. This research will determine the factors most strongly governing the interaction between humans and native fauna in Australia over the last 46 millennia. Our approach is powerful and novel because it will effectively draw together multidisciplinary evidence on natural resource exp ....Reconstructing past population dynamics to understand human and climatic impacts in prehistory. More than 100 species have become extinct since humans first colonised Australia, and over 1000 are considered threatened. This research will determine the factors most strongly governing the interaction between humans and native fauna in Australia over the last 46 millennia. Our approach is powerful and novel because it will effectively draw together multidisciplinary evidence on natural resource exploitation and habitat alteration by ancient people, and the influence of dramatic climatic shifts on the Australian biota. Information on past biological responses to environmental change is critical to properly contextualising the current impact, and long-term consequences of, threats such as global warming, habitat loss and invasive species.Read moreRead less
Carbon in - carbon out: can carbon inputs keep up with losses in peatland? This project aims to quantify the current and predict the future carbon balance of a high altitude, carbon-dense ecosystem, namely sub-alpine grassy peatland, by measuring how environmental variables including experimental warming control the fluxes of carbon and water into and out of the system. In this way, this project will produce new knowledge on the susceptibility of high-altitude peaty soils to climate change. Expe ....Carbon in - carbon out: can carbon inputs keep up with losses in peatland? This project aims to quantify the current and predict the future carbon balance of a high altitude, carbon-dense ecosystem, namely sub-alpine grassy peatland, by measuring how environmental variables including experimental warming control the fluxes of carbon and water into and out of the system. In this way, this project will produce new knowledge on the susceptibility of high-altitude peaty soils to climate change. Expected outcomes include an enhanced ability to predict future carbon accumulation rates and the resilience of the vital water-storage and filtration services provided by these systems. This project will enhance outputs from new infrastructure and assist planning for future flood and drought management across SE Australia.Read moreRead less
The 'paper war': Missionary Textuality and Early Nineteenth-Century Australian Colonial Culture. Early nineteenth-century Australian texts reverberate with the anxieties and controversies surrounding colonisation. The morality of colonisation and indigenous-settler relationships were hotly debated in a proliferation of books, pamphlets, letters, and editorials, and in this religious personnel, including missionaries, played a pivotal role. Yet no critical analysis of colonial missionary writing ....The 'paper war': Missionary Textuality and Early Nineteenth-Century Australian Colonial Culture. Early nineteenth-century Australian texts reverberate with the anxieties and controversies surrounding colonisation. The morality of colonisation and indigenous-settler relationships were hotly debated in a proliferation of books, pamphlets, letters, and editorials, and in this religious personnel, including missionaries, played a pivotal role. Yet no critical analysis of colonial missionary writing exists. This project conducts archival research into texts produced by a linked network of religious/missionary figures, focusing on the Lake Macquarie mission run by Lancelot Threlkeld, and analyses these through theories of colonial discourse and textuality. Research outcomes include original, innovative contributions to Australian literary/cultural studies and international colonial/postcolonial studies.Read moreRead less
