Summary
Atmospheric trace gases: Fuelling the dormant microbial majority. This project aims to determine the physiological roles and ecological significance of hydrogen, methane and carbon monoxide scavenging. Bacteria adapt to adverse environmental conditions such as energy-starvation by entering dormant states. The fuel sources that sustain this dormant majority have yet to be resolved. Aerobic soil bacteria survive by scavenging trace gases from the atmosphere; they literally live on thin air. These ....Atmospheric trace gases: Fuelling the dormant microbial majority. This project aims to determine the physiological roles and ecological significance of hydrogen, methane and carbon monoxide scavenging. Bacteria adapt to adverse environmental conditions such as energy-starvation by entering dormant states. The fuel sources that sustain this dormant majority have yet to be resolved. Aerobic soil bacteria survive by scavenging trace gases from the atmosphere; they literally live on thin air. These trace gas scavengers are the major biological sinks in the global methane and hydrogen cycles. This project aims to study entire ecosystems of trace gas scavengers, which could enhance understanding of soil microbial ecology and biogeochemical cycling. By studying the regulation and distribution of gas scavenging, we can better model how these sinks respond to global change.Read moreRead less

Microflow ultra high pressure liquid chromatography – high resolution mass spectrometry for chemical exposure monitoring: Identifying new chemicals of interest in environmental or biological samples is the first critical step toward understanding their impact to human and environment. A state-of-the-art microflow ultra high performance liquid chromatography high resolution mass spectrometer is fundamental to extend our research capabilities to new environmental contaminants and environmental exposure biomarkers, as well as consumption biomarkers of new illicit drugs and their metabolites. This instrument will fill an important gap in our capacity to link health/ecological risk to unknown chemicals and will allow interdisciplinary researchers to advance work in environmental toxicology, chemistry and forensics.Read moreRead less
The evolution of cooperative communication. This interdisciplinary project will provide a broad understanding of communication in a model ecological system involving ants, lycaenid butterflies, and host-plants. The project will reveal the nature of the chemical signals used to communicate, and their role in the origin, maintenance, and loss of mutualistic and parasitic associations.

Sensor calibration facility for spectral and thermal remote sensing. This project aims to establish a calibration facility for the radiometric and spectral correction of hyperspectral and thermal sensors for ultrahigh-resolution remote sensing. Sensor calibration and characterisation is critical to the accuracy of hyperspectral and thermal data products, however, there is no central facility in Australia for this purpose.

New Directions in Bayesian Statistics: formulation, computation and application to exemplar challenges. Bayesian statistics is a fundamental statistical and machine learning approach for density estimation, data analysis and inference. However, there remain open questions regarding the formulation of the model, the likelihood and priors, and efficient computation.

Bayesian statistics is a fundamental statistical and machine learning approach for density estimation, data analysis and inference. However, there remain open questions regarding the formulation of the model, the likelihood and priors, and efficient computation. This project proposes new approaches that address these issues, and applies them to two exemplar challenges: the impact of climate change on the Great Barrier Reef and better understanding neurological diseases related aging, in particular Parkinson's Disease.

ARC Centre of Excellence for Mathematical and Statistical Frontiers of Big Data, Big Models, New Insights. In today's world, massive amounts of data in a variety of forms are collected daily from a multitude of sources. Many of the resulting data sets have the potential to make vital contributions to society, business and government, as well as impact on international developments, but are so large or complex that they are difficult to process and analyse using traditional tools.

In today's world, massive amounts of data in a variety of forms are collected daily from a multitude of sources. Many of the resulting data sets have the potential to make vital contributions to society, business and government, as well as impact on international developments, but are so large or complex that they are difficult to process and analyse using traditional tools. The aim of this Centre is to create innovative mathematical and statistical models that can uncover the knowledge concealed within the size and complexity of these big data sets, with a focus on using the models to deliver insight into problems vital to the Centre's Collaborative Domains: Healthy People, Sustainable Environments and Prosperous Societies.Read moreRead less

Resolving human-flying fox conflict in the face of environmental change. This project aims to identify socially-acceptable priority areas to be managed for the long-term viability of flying-foxes under a changing climate, and develop strategies to mitigate human-flying fox conflict, using ecological and social analysis in a decision-theoretic framework. Flying-foxes are nationally protected mammals pivotal to Australia’s forest ecosystems, but are threatened by habitat loss, extreme weather and legal culls at orchards. Their exceptional mobility puts them in frequent conflict with human settlements, leading to forced dispersals from roosts. Anticipated outcomes are the conservation of Australia’s flying-foxes and international understanding of how to resolve human conflict with highly mobile species that are threatened but locally abundant and controversial.Read moreRead less
Tibet's rivers in the Anthropocene: history and present trajectories. This project aims to produce a multifaceted history of the eastern Tibetan Plateau's rivers, focusing on the increasing human impacts during the Anthropocene.

This project aims to produce a multifaceted history of the eastern Tibetan Plateau's rivers, focusing on the increasing human impacts during the Anthropocene. It will combine data from archival, cultural and oral sources in multiple languages with the results of scientific studies of river flow, water quality, and sediment, ice, and tree-rings analysis. The project will produce both historical narratives and graphic representations that model past land and water usage. The results of the project will underpin environmental policy for this hydrologically and ecologically crucial region, including the development of a paradigm of care based on the region's indigenous cultural resources.Read moreRead less
The role of song in Kaytetye and Warlpiri biocultural knowledge. This project aims to integrate Indigenous Ecological Knowledge with Indigenous ceremonial knowledge in two central Australian Aboriginal languages: Kaytetye and Warlpiri.

This project aims to integrate Indigenous Ecological Knowledge with Indigenous ceremonial knowledge in two central Australian Aboriginal languages: Kaytetye and Warlpiri. With a multidisciplinary team and by building on existing lexical and musical corpora, the project expects to produce the first biocultural monographs. Identification of biota and human uses of them will be expanded with their song, site of origin and kinship affiliation; thus advancing knowledge of how societies interact with the natural world and the role of music in retaining knowledge. Expected benefits of this project are greater intergenerational transfer of Indigenous biocultural knowledge through working on country and enhanced Indigenous capacity. Read moreRead less
Modelling dynamics in spatial ecology. This project addresses how birth, death and movement drive patterns of plants and animals in space and time.

This project addresses how birth, death and movement drive patterns of plants and animals in space and time. We aim to apply and extend dynamical statistical models grounded in theory. Dynamical models are needed for us to understand how species and ecological communities respond to environmental change and disturbance including bushfires, climate change and extremes and species invasion. Using data from forest plots and animal movement, we aim to understand influences on individuals and species, and how to use that to generate robust predictions. The project is expected to produce statistical models and software for use by ecologists. This should help predict, and manage, ecological impacts of environmental change and disturbances.Read moreRead less
