Every cloud drop is formed from a microscopic aerosol particle, known as a cloud condensation nuclei (CCN). In unpolluted environments the CCN particles originate from biogenic sources. Determining the magnitude and driving factors of biogenic aerosol production in different ecosystems is crucial to the development and improvement of climate models. This project aims to determine the mechanisms of new particle production from one of the biggest ecosystems in Australia, the Great Barrier Reef. It is expected that the project will establish whether marine aerosol along the Queensland coast is coral-derived and show that this aerosol can affect the CCN concentration and therefore cloud formation and the hydrological cycle.Read moreRead less
Formation, photochemistry and fate of gas-phase peroxyl radicals. This project aims to understand how peroxyl radical reactions modulate the composition of air. The gas-phase chemical reactions of organic peroxyl radicals contribute to air quality in clean and polluted environments. However, experimental observations of these reaction intermediates and the complex mechanisms governing their formation and fate are limited. This project will use mass spectrometry and laser-based methods to interro ....Formation, photochemistry and fate of gas-phase peroxyl radicals.

Diagnosing river health using invertebrate traits and DNA barcodes. Diagnosing river health using invertebrate traits and DNA barcodes. This project aims to develop indices that link change in invertebrate communities to specific environmental stressors, and combine these indices with innovative, low cost molecular approaches to species identification to rapidly identify the causes of decline.

Diagnosing river health using invertebrate traits and DNA barcodes. This project aims to develop indices that link change in invertebrate communities to specific environmental stressors, and combine these indices with innovative, low cost molecular approaches to species identification to rapidly identify the causes of decline. River health assessment methods, usually based on aquatic invertebrates, identify if rivers are impaired but must be developed to identify the causes of decline. The intended outcomes are improved sustainable water resource management within and among states, and improved natural resource policy development.Read moreRead less
Can we see the wood for the trees? Effective restoration strategies in rapidly changing subtropical river systems. Addressing the issue of degraded waterways nationally will cost billions of dollars; in southeast Queensland alone it is estimated that it will cost $500 million. Fundamental research is needed to ensure such efforts achieve the desired outcomes. Previous research has shown riverbank erosion is a key stressor for water quality.

Addressing the issue of degraded waterways nationally will cost billions of dollars; in southeast Queensland alone it is estimated that it will cost $500 million. Fundamental research is needed to ensure such efforts achieve the desired outcomes. Previous research has shown riverbank erosion is a key stressor for water quality. This project aims to link fluvial disturbance with the capacity for effective riparian restoration in subtropical river systems at a local, reach and whole of catchment scale. The outcome aims to develop decision-support tools and methods for industry partners to invest in catchment-scale restoration activities in order to manage the risks to drinking water quality and aquatic ecosystem health from riverbank erosion.Read moreRead less
Restoring functional links between riparian zones and streams by enhancing structural retention. This project aims to test whether structural retention, whereby plant detritus (logs, bark, leaves) is trapped and retained within river channels, can offset the impacts caused by widespread clearance of vegetation along river banks, a widespread problem in Australia and the world. Theoretically, retention is a major environmental driver of ecosystem change in rivers, but this has rarely been tested, ....Restoring functional links between riparian zones and streams by enhancing structural retention. This project aims to test whether structural retention, whereby plant detritus (logs, bark, leaves) is trapped and retained within river channels, can offset the impacts caused by widespread clearance of vegetation along river banks, a widespread problem in Australia and the world. Theoretically, retention is a major environmental driver of ecosystem change in rivers, but this has rarely been tested, particularly in a restoration context. The aim of this project is to show that increasing retention results in higher species diversity, thus providing managers with a relatively straightforward method for improving the environmental conditions of rivers, while simultaneously testing three hypotheses about rectifying ecosystem degradation caused by human impacts.Read moreRead less

Summary
Stochastic mathematical modelling of the Wnt signalling pathway. The Wnt signalling pathway is pivotal in multicellular organisms, regulating cellular processes such as proliferation, apoptosis and migration. Faulty Wnt signalling is associated with degenerative diseases, developmental disorders and cancers and is therefore a potential target for therapeutic drugs. This project will perform a stochastic spatial simulation of the Wnt signalling pathway which will be matched to experimental data. ....Stochastic mathematical modelling of the Wnt signalling pathway. The Wnt signalling pathway is pivotal in multicellular organisms, regulating cellular processes such as proliferation, apoptosis and migration. Faulty Wnt signalling is associated with degenerative diseases, developmental disorders and cancers and is therefore a potential target for therapeutic drugs. This project will perform a stochastic spatial simulation of the Wnt signalling pathway which will be matched to experimental data. The model will be extended to integrate with the cell cycle. Increased proliferation in tumours has been linked to mutations in Wnt components. Using the extended model, the effect of Wnt-targeting therapeutic cancer drugs on cancer cell proliferation rates will be predicted and compared to experiments.Read moreRead less
