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.

Summary
High throughput nitrogen analysis for ecological studies. Australian environments are unproductive partly because they contain little Nitrogen (N) and changes in atmospheric CO2 will exacerbate this. Furthermore, animals cannot extract all the N from the plants they eat. An assay has been developed that measures how much they can extract (available N) and it is intended to use it to measure habitat quality and the effects of climate change over large tracts of land. This requires thousands of ....High throughput nitrogen analysis for ecological studies. Australian environments are unproductive partly because they contain little Nitrogen (N) and changes in atmospheric CO2 will exacerbate this. Furthermore, animals cannot extract all the N from the plants they eat. An assay has been developed that measures how much they can extract (available N) and it is intended to use it to measure habitat quality and the effects of climate change over large tracts of land. This requires thousands of N analyses. The equipment we are requesting - a LECO combustion analyser, allows us to analyse samples quickly and safely and uses fewer chemicals and much less water than do traditional machines.Read moreRead less
Re-evaluating the role of tannins in Australian forest ecosystems. As atmospheric CO2 concentrations rise, eucalypts will respond by decreasing the amount of protein in the leaves and increasing the concentrations of toxins called tannins. Together this will have the effect of making the leaves harder for herbivores to eat and slower to break down on the forest floor. We have developed a new way of measuring these effects and will use it to show which eucalypt communities climate change will mo ....Re-evaluating the role of tannins in Australian forest ecosystems. As atmospheric CO2 concentrations rise, eucalypts will respond by decreasing the amount of protein in the leaves and increasing the concentrations of toxins called tannins. Together this will have the effect of making the leaves harder for herbivores to eat and slower to break down on the forest floor. We have developed a new way of measuring these effects and will use it to show which eucalypt communities climate change will most affect and so which forests will become less able to support fauna. Apart from contributing to the better management of Australian forests, this project also enhances the National Carbon Accounting System by measuring how tannins influence litter decomposition and explaining the link with leaf chemistry.Read moreRead less

The Heron Island Climate Change Observatory: An In-Situ Ocean Acidification and Carbonate Chemistry Monitoring Platform. Climate change and ocean acidification are widely recognized as key threats to Australia's natural ecosystems, yet we are currently ill-equipped to respond due to poor knowledge of the scale/nature of the impacts. The Heron Island Climate Change Observatory will establish key infrastructure that will rapidly improve our understanding of the impacts of ocean acidification whic ....The Heron Island Climate Change Observatory: An In-Situ Ocean Acidification and Carbonate Chemistry Monitoring Platform. Climate change and ocean acidification are widely recognized as key threats to Australia's natural ecosystems, yet we are currently ill-equipped to respond due to poor knowledge of the scale/nature of the impacts. The Heron Island Climate Change Observatory will establish key infrastructure that will rapidly improve our understanding of the impacts of ocean acidification which is important to local communities and the nation given that coral reefs support over $6 billion in revenue (and employ 60,000 people) each year. This critically important information is essential to the management and protection of Australia's coral reefs, including the Great Barrier Reef.

Anatomy of a biodiversity hotspot: investigating the evolutionary and ecological basis of high plant diversity in southwestern Australia. Southwestern Australia - Australia's only global biodiversity hotspot - has an exceptionally rich flora but has suffered extensive habitat loss, so many rare plants are threatened with extinction. Further, this region is expected to suffer severely under projected climate change scenarios, lending urgency to efforts to describe and understand the regions plant ....Anatomy of a biodiversity hotspot: investigating the evolutionary and ecological basis of high plant diversity in southwestern Australia. Southwestern Australia - Australia's only global biodiversity hotspot - has an exceptionally rich flora but has suffered extensive habitat loss, so many rare plants are threatened with extinction. Further, this region is expected to suffer severely under projected climate change scenarios, lending urgency to efforts to describe and understand the regions plant biodiversity. This project will provide the first description and analysis of an important but hitherto little-known aspect of biodiversity, the evolutionary structure of ecological communities. This will enhance our understanding of how communities are assembled, providing a stronger scientific basis for sustainable management of the southwest's biodiversity.Read moreRead less
Fitness in free-living populations in a changing world. We understand very little about the evolutionary and ecological response of populations to periods of rapid environmental change or volatility. New methods raise the possibility dissecting the various causes of change, and their demographic consequences. However, these methods depend on long-term studies of the genealogy, survival and reproductive success of individuals. Data on the iconic superb fairy-wren will be used to establish this ....Fitness in free-living populations in a changing world. We understand very little about the evolutionary and ecological response of populations to periods of rapid environmental change or volatility. New methods raise the possibility dissecting the various causes of change, and their demographic consequences. However, these methods depend on long-term studies of the genealogy, survival and reproductive success of individuals. Data on the iconic superb fairy-wren will be used to establish this species as a model for the study of climate change, and the extent to which living in social groups helps or hinders evolutionary response to such change.Read moreRead less
