Summary
Purification of contaminated wastewaters by modified Bayer layered double hydroxides. This project intends to develop enhanced adsorbent materials, prepared from industrial wastewater and seawater, for the decontamination of environments affected by Australian industries. This inexpensive novel material will be applicable to a wide range of purification applications and will reduce the environmental impact of Australian industries.
Optimising synthesis, developing delivery systems and resolving the ecological significance of the chemical in smoke that promotes seed germination. Discovery of the identity of the component in smoke (a butenolide) that promotes seed germination provides the research platform to deliver smoke-like efficacy for germination of native species used in horticulture, land restoration and biodiversity conservation. The study will investigate five key areas to deliver the national benefits of our disco ....Optimising synthesis, developing delivery systems and resolving the ecological significance of the chemical in smoke that promotes seed germination. Discovery of the identity of the component in smoke (a butenolide) that promotes seed germination provides the research platform to deliver smoke-like efficacy for germination of native species used in horticulture, land restoration and biodiversity conservation. The study will investigate five key areas to deliver the national benefits of our discovery: investigate efficacy of butenolide in seed germination; resolve mechanisms of dormancy release via butenolide; optimise synthesis pathways for production of butenolide and germination-effective analogues; investigate the ecologiocal context and natural abundance of butenolide; resolve synthesis and delivery systems for horticulture and restoration.Read moreRead less
Pelletisation of seawater-neutralised bauxite refinery residues (Bauxsol?) for construction of permeable reactive barriers to treat flowing acid mine waters. Acid mine drainage (AMD) occurs where sulphides (mostly pyrite, but also sulphides of other metals) are exposed to oxygen and water; the estimated global liability from AMD is over US$300 billion. There is currently no cost-effective way to prevent the release of acid and heavy metals from exposed sulphide minerals especially at abandoned m ....Pelletisation of seawater-neutralised bauxite refinery residues (Bauxsol?) for construction of permeable reactive barriers to treat flowing acid mine waters. Acid mine drainage (AMD) occurs where sulphides (mostly pyrite, but also sulphides of other metals) are exposed to oxygen and water; the estimated global liability from AMD is over US$300 billion. There is currently no cost-effective way to prevent the release of acid and heavy metals from exposed sulphide minerals especially at abandoned mine sites. This study investigates the pelletisation and use of neutralised bauxite refinery residues (Bauxsol?) to treat flowing metal-rich acid mine drainage waters using reactive-barriers that will neutralise acid and remove heavy metals without impeding flow.Read moreRead less
Predicting the effects of desalination plant discharge in a changing ocean environment. This project will test whether changes to the ocean environment associated with climate change (a warmer and more acidic ocean) will influence the sensitivity of marine organisms to hyper-saline discharges. Novel toxicity tests will be developed using locally relevant species that will provide crucial tools for the management of coastal habitats.
Exploiting natural processes to effectively remediate acidified coastal environments. Working with local government, industry and communities, this project aims to identify how natural processes can best be manipulated to limit acid sulfate soil discharge in many Australian estuaries. The expected outcomes are systematic remediation of these areas and improvement in estuarine water quality.
The regeneration niche of invasive plants: managing the weed-shaped hole. In Australia $20 million was spent on weed control in natural areas in 2001-02 and is indicative of the level of funding for weed control programs each year. An understanding of how current weed control programs affect the regeneration of weeds in the system will give us novel insights into the persistence of weed populations despite sustained investment in control. Environmental weeds threaten biodiversity and ecosystem ....The regeneration niche of invasive plants: managing the weed-shaped hole. In Australia $20 million was spent on weed control in natural areas in 2001-02 and is indicative of the level of funding for weed control programs each year. An understanding of how current weed control programs affect the regeneration of weeds in the system will give us novel insights into the persistence of weed populations despite sustained investment in control. Environmental weeds threaten biodiversity and ecosystem function in unique Australian communities, better management of weeds will have conservation, ecosystem service provision and amenity values nationally. This project highlights the importance of understanding the weed regeneration niche for successful long-term and sustainable control.Read moreRead less
Optimising seed sourcing for effective ecological restoration. This project aims to address the sourcing of native seed for ecological restoration under global change. The great demand for native seed to deliver ecological restoration provides a clear need and responsibility to use this seed as efficiently as possible. This project expects to develop detailed new knowledge that links plant and environmental genomics, plant physiology, seed and soil biology in embedded experiments at post-mining ....Optimising seed sourcing for effective ecological restoration. This project aims to address the sourcing of native seed for ecological restoration under global change. The great demand for native seed to deliver ecological restoration provides a clear need and responsibility to use this seed as efficiently as possible. This project expects to develop detailed new knowledge that links plant and environmental genomics, plant physiology, seed and soil biology in embedded experiments at post-mining rehabilitation sites. Expected outcomes include clear industry guidelines that refine seed sourcing strategies for ecological restoration for current and future climates. This should provide significant benefits for improved ecological restoration outcomes when using native seed today and into the future.Read moreRead less
Planning for the impacts of land-uses on coral reef fisheries. This projects aims to develop models that can determine the ecological and economic impacts of land-use changes (e.g. agriculture) on fisheries and assess alternative land-use plans that seek to maximise economic opportunity while protecting fisheries. Fisheries support the livelihoods of 12 per cent of the world’s population. Land-based activities are among the most significant threats to coral reef fisheries because sediments and n ....Planning for the impacts of land-uses on coral reef fisheries. This projects aims to develop models that can determine the ecological and economic impacts of land-use changes (e.g. agriculture) on fisheries and assess alternative land-use plans that seek to maximise economic opportunity while protecting fisheries. Fisheries support the livelihoods of 12 per cent of the world’s population. Land-based activities are among the most significant threats to coral reef fisheries because sediments and nutrients degrade reefs, yet they are often ignored in fisheries management. By improving the sustainability of coastal development, biodiversity conservation, and health of fisheries, the models developed by the project could deliver socio-economic and environmental benefits for millions of people reliant upon fisheries for their livelihoods.Read moreRead less
Reproducibility and open science in environmental research. The goal of this project is to improve the reproducibility and transparency of environmental science. Disturbingly low levels of reproducibility have recently been uncovered in other disciplines, and there are good reasons to suspect the same conditions in environmental science. However, it has thus far been excused from evaluation because of the large spatial scales, long time horizons and dependencies among processes that prohibit dir ....Reproducibility and open science in environmental research. The goal of this project is to improve the reproducibility and transparency of environmental science. Disturbingly low levels of reproducibility have recently been uncovered in other disciplines, and there are good reasons to suspect the same conditions in environmental science. However, it has thus far been excused from evaluation because of the large spatial scales, long time horizons and dependencies among processes that prohibit direct replication of empirical field research. The project plans to assess the reproducibility of environmental research and develop systematic review methods that account for bias in published research. In this way, it seeks to contribute to the standards for statistical inference and reporting in the discipline, and facilitate a cultural shift to ‘Open Science’ to ensure a more reliable evidence base for environmental decisions.
