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.

Microbial community stability dynamics to environmental triggers. This project aims to advance our knowledge of the structural/functional dynamics of complex microbial communities by defining stability in response to environmental influences such as nutrient stress, pathogen invasion and antibiotics/chemicals. Using innovative microbial consortia modelling, to identify communities at risk of homeostatic disruption, we will develop and test pre-emptive microbial manipulation strategies for restor ....Microbial community stability dynamics to environmental triggers. This project aims to advance our knowledge of the structural/functional dynamics of complex microbial communities by defining stability in response to environmental influences such as nutrient stress, pathogen invasion and antibiotics/chemicals. Using innovative microbial consortia modelling, to identify communities at risk of homeostatic disruption, we will develop and test pre-emptive microbial manipulation strategies for restoring community stability. This project will yield significant global impact and economic/health benefit for humans and animals.Read moreRead less
Australia's ocean microbiome: how the diversity and functionality of microbes influence key oceanographic provinces. Every millilitre of seawater contains millions of microbes that maintain the health of our planet, but their identity and function in Australian waters is undefined. This project will identify the microbes inhabiting Australian marine systems, elucidate the services they provide, and predict how they will be affected by future environmental changes
Incorporating new knowledge of phytoplankton diversity and nutrient utilisation into an ocean-climate model to improve forecasts of ocean function. Phytoplankton drives ocean biogeochemical cycles and regulate Earth’s climate yet are poorly represented in ocean-climate models. This project will use advanced cell sorting and analysis techniques and innovative selection experiments to gain a deeper understanding of phytoplankton diversity and nutrient utilisation under projected climate change. Th ....Incorporating new knowledge of phytoplankton diversity and nutrient utilisation into an ocean-climate model to improve forecasts of ocean function. Phytoplankton drives ocean biogeochemical cycles and regulate Earth’s climate yet are poorly represented in ocean-climate models. This project will use advanced cell sorting and analysis techniques and innovative selection experiments to gain a deeper understanding of phytoplankton diversity and nutrient utilisation under projected climate change. This new knowledge will be used to improve the biological structure of an existing coupled ocean-climate model and reduce key uncertainties in forecasts of ocean function. This research will provide managers and industry with more accurate insight into the effects of ongoing climate change on the delivery of ecosystem services in eastern Australian waters.Read moreRead less
Determinants of substrate preferences and environmental applications of the copper membrane monooxygenases. The project aims to improve sustainability of environmental problems related to methane emissions, nitrogen cycling and pollution. We are developing tools targeting microbial genes correlated to all these issues. Data from these tests provides the information needed for monitoring environmental health and development of sustainable solutions.

A time of flight secondary ion mass spectrometer facility for elemental and isotopic imaging of ultra-fine features: Microbiology has long been an area of strength in Australian science. With recent technological advances microbiology has entered a new golden age unveiling an extraordinary level of diversity and the central role of microbes in global biogeochemistry. The 'omics' era is generating endless hypotheses regarding geochemical processes carried out by microbes and this necessitates the application of advanced technologies to generate empirical support. Time of flight secondary ion mass spectrometry has emerged as a key tool to unravel elemental cycling carried out by microorganisms in mixed species communities in contexts ranging from terrestrial to marine ecology and from groundwater bioremediation to biogas production biotechnologies.Read moreRead less
Defining the evolution of pathogen virulence to enhance rabbit biocontrol. Rabbits impose a major economic and ecological burden on Australia. Biocontrols involving viruses are the best means to regulate rabbit populations, although they often have transient effectiveness. It is therefore essential to determine why some viruses retain the high virulence essential for effective biocontrol, while others are consistently benign. Through bioinformatic and experimental studies of two rabbit viruses w ....Defining the evolution of pathogen virulence to enhance rabbit biocontrol. Rabbits impose a major economic and ecological burden on Australia. Biocontrols involving viruses are the best means to regulate rabbit populations, although they often have transient effectiveness. It is therefore essential to determine why some viruses retain the high virulence essential for effective biocontrol, while others are consistently benign. Through bioinformatic and experimental studies of two rabbit viruses with markedly different virulence, Rabbit Haemorrhagic Disease virus (high virulence) and Australian rabbit calicivirus (low virulence), this project will determine the molecular mechanisms that control virulence and the factors that shape virulence evolution. Ultimately, this research will help improve rabbit biocontrol in Australia.Read moreRead less
