The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Constructing a temporally-constrained palaeoecological model of Quaternary faunal evolution and extinction in eastern Australia. Increased climatic variability and human-induced environmental degradation have had severe impacts on biodiversity, socio-economic sustainability and possibly our own future survival, thus attracting global attention. This study will help unravel the causes of the extinctions of Australia's large-size animals (megafauna) during the periods of last glaciation and earlie ....Constructing a temporally-constrained palaeoecological model of Quaternary faunal evolution and extinction in eastern Australia. Increased climatic variability and human-induced environmental degradation have had severe impacts on biodiversity, socio-economic sustainability and possibly our own future survival, thus attracting global attention. This study will help unravel the causes of the extinctions of Australia's large-size animals (megafauna) during the periods of last glaciation and earliest human colonisation of Australia. Investigating the causes of megafauna extinction is essential for an understanding of how those prehistoric events shaped the modern biota, and for the development of conservation strategies for our endemic faunas in an era of increased climatic and environmental variability and vulnerability.Read moreRead less
ARC Research Network for Understanding and Managing Australian Biodiversity. Biodiversity research is strong in Australia but is highly uncoordinated and, along with recent major breakthroughs in both theory and techniques, has highlighted the need for a Network to properly integrate research and focus it on the most appropriate scale. This Network aims to bring together a diverse spectrum of highly experienced and early career researchers to pool their ideas and expertise to allow them to deter ....ARC Research Network for Understanding and Managing Australian Biodiversity. Biodiversity research is strong in Australia but is highly uncoordinated and, along with recent major breakthroughs in both theory and techniques, has highlighted the need for a Network to properly integrate research and focus it on the most appropriate scale. This Network aims to bring together a diverse spectrum of highly experienced and early career researchers to pool their ideas and expertise to allow them to determine how best to describe Australia's current biodiversity and the biological and environmental history leading up to the present. A major outcome will be the ability to predict the impacts of environmental change on biodiversity to assist management decisions across Australia, with lessons of global importance.Read moreRead less
The abundance and isotope composition of pyrogenic carbon in tropical savannas. Tropical savanna burning represents an important but poorly understood component of the global carbon cycle. This project will quantify the dynamics of pyrogenic carbon (charcoal, soot, biochar) production and dispersal during savanna fires. Pyrogenic carbon is important because it can persist in the environment for thousands of years. Hence it represents both a 'sink' for carbon and a source of information about pas ....The abundance and isotope composition of pyrogenic carbon in tropical savannas. Tropical savanna burning represents an important but poorly understood component of the global carbon cycle. This project will quantify the dynamics of pyrogenic carbon (charcoal, soot, biochar) production and dispersal during savanna fires. Pyrogenic carbon is important because it can persist in the environment for thousands of years. Hence it represents both a 'sink' for carbon and a source of information about past environments. The project will also assist in validating 'biochar' as a new tool for carbon sequestration, an enable a deeper understanding of the interactions between fire, humans, vegetation and climate.Read moreRead less
450 Million year history of plant gas exchange capacity and the role of atmospheric carbon dioxide. Our planet faces an increase in atmospheric carbon dioxide that is unprecedented in human history, but has occurred in ancient times. By studying the relationship between past changes in atmospheric carbon dioxide, plant gas exchange and climate we will gain powerful global insight into future scenarios of continental carbon and water fluxes. This global perspective is essential for Australia to a ....450 Million year history of plant gas exchange capacity and the role of atmospheric carbon dioxide. Our planet faces an increase in atmospheric carbon dioxide that is unprecedented in human history, but has occurred in ancient times. By studying the relationship between past changes in atmospheric carbon dioxide, plant gas exchange and climate we will gain powerful global insight into future scenarios of continental carbon and water fluxes. This global perspective is essential for Australia to assess its vulnerability to global climate change in relation to other nations, thereby informing national planning of landscape resource use, including primary industry, water infrastructure and carbon trading.Read moreRead less

Summary
High-resolution ITRAX XRF core scanning facility for global change research. This facility will enable researchers to obtain high-resolution geochemical profiles in the study of environmental change and climate variability. It will provide archive data on the variation of density and chemical element composition along sediment and soil cores, rock cores, wood samples, speleothems and corals. These archives contain important information such as human activity, climate variability, water quality c ....High-resolution ITRAX XRF core scanning facility for global change research. This facility will enable researchers to obtain high-resolution geochemical profiles in the study of environmental change and climate variability. It will provide archive data on the variation of density and chemical element composition along sediment and soil cores, rock cores, wood samples, speleothems and corals. These archives contain important information such as human activity, climate variability, water quality changes, pollution histories, recent geomorphological change, land-use change, introduction of invasive species and the occurrence of bushfires. A better understanding of the occurrence and timing of these major environmental issues is of national and regional importance.Read moreRead less
