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.

Avoiding coral bleaching: investigation into the repair of damaged photosynthetic machinery in symbiotic algae (symbiodinium) within corals. Photosynthesis in symbiotic algae within corals is essential for a healthy alga-coral symbiotic relationship. This project will provide new insights into how symbiotic algae maintain higher photosynthetic performance in corals through elucidating the mechanism associated with the repair of photodamaged photosynthetic machinery.
Disentangling climate and evolutionary controls over the temperature dependence of leaf respiration. The project will use field and laboratory studies to establish if there are systematic differences in the temperature responses of leaf respiration in plants adapted to hot and cold environments. The results will enable climate modellers to better predict impacts of climate change on carbon exchange between vegetation and the atmosphere.
Global change in the sub-antarctic - Temperature response of vascular plant species from Macquarie and Heard Islands. The aim is to understand how subantarctic and alpine plant species that have evolved, respectively, in equable and highly variable temperature regimes will respond to increase in temperature resulting from global warming and climate change. The proposed project will identify species that are likely to benefit from, or are vulnerable to, rising temperatures. Processes underlying a ....Global change in the sub-antarctic - Temperature response of vascular plant species from Macquarie and Heard Islands. The aim is to understand how subantarctic and alpine plant species that have evolved, respectively, in equable and highly variable temperature regimes will respond to increase in temperature resulting from global warming and climate change. The proposed project will identify species that are likely to benefit from, or are vulnerable to, rising temperatures. Processes underlying adaptation and acclimation of plant growth to increasing temperature will also be identified. These results will be significant for conservation of biodiversity and management of Australia's unique subantarctic and alpine flora.Read moreRead less
A step change in modeling leaf respiration-photosynthesis relationships . This project aims to use innovative, high-throughput technologies to develop a novel framework that links daytime photosynthesis and starch/amino acid mobilisation to variations in night-time leaf respiration. Variations in leaf respiration can have large impacts on ecosystem functioning and the Earth’s climate. Although advances have been made in respiration modelling, current models are unable to predict dynamic, day-to- ....A step change in modeling leaf respiration-photosynthesis relationships . This project aims to use innovative, high-throughput technologies to develop a novel framework that links daytime photosynthesis and starch/amino acid mobilisation to variations in night-time leaf respiration. Variations in leaf respiration can have large impacts on ecosystem functioning and the Earth’s climate. Although advances have been made in respiration modelling, current models are unable to predict dynamic, day-to-day variations in respiratory rates. Expected outcomes include equations that predict daily variations in night-time leaf respiration for environments across Australia and overseas. Benefits to planners include the ability to more accurately model vegetation-atmosphere carbon exchange and future changes in climate. Read moreRead less
The causes and effects of mortality in tropical Australian trees. Drought can cause the widespread death of tropical trees resulting in large emissions of carbon dioxide to the atmosphere, but predictions of tree death during drought remain rudimentary. This project will combine new data and modelling on how Australian tropical trees respond to drought to improve estimates of tree mortality risk and its impacts.

Summary
Plant Phenomics Imaging and Analysis Facility. The Australian plant science community faces a major challenge in being able to comprehensively characterise the performance or phenotype of plants in a high throughput manner necessary for post-genomic era science with model plant species, smart-breeding of crop plants and to assess plant-environment interactions. Our capacity to accurately 'phenotype' either a new mutant or a new variety has fallen behind out capacity to generate novel genetic mat ....Plant Phenomics Imaging and Analysis Facility. The Australian plant science community faces a major challenge in being able to comprehensively characterise the performance or phenotype of plants in a high throughput manner necessary for post-genomic era science with model plant species, smart-breeding of crop plants and to assess plant-environment interactions. Our capacity to accurately 'phenotype' either a new mutant or a new variety has fallen behind out capacity to generate novel genetic material. This facility will significantly boost research outputs across a range of disciplines pivotal to Australia's future agricultural plant productivity and environmental sustainability. Read moreRead less
