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

This project aims to establish an environmental radioactivity research centre, equipped with ultra-low background and high-resolution alpha and gamma spectrometry systems, radon detectors and radium delayed coincidence counters. The centre will address a critical demand in Australia for precise analysis of a large suite of natural and artificial radionuclides, which will be used as tracers and chronological tools to investigate key questions in oceanography and the mining and energy, archaeological, agricultural, and forestry sectors. The facility is expected to substantially increase expertise and training in radionuclides in Australia, and promote high-level research collaborations and outputs of both national and international significance. Major outcomes of the proposed facility include better understanding of how oceans regulate climate and improved capacity to assess effects of radiation on natural ecosystems.Read moreRead less
Resolving the role of dryland flooding in the global carbon cycle. Aquatic sources of carbon dioxide and methane are globally significant, but unknown for flooded drylands. The aim of this project is to use an innovative combination of well-integrated methodologies to determine if flooded drylands release large amounts of carbon dioxide and methane. This project is significant because this release of carbon dioxide and methane has not previously been accounted for and may change the magnitude of ....Resolving the role of dryland flooding in the global carbon cycle. Aquatic sources of carbon dioxide and methane are globally significant, but unknown for flooded drylands. The aim of this project is to use an innovative combination of well-integrated methodologies to determine if flooded drylands release large amounts of carbon dioxide and methane. This project is significant because this release of carbon dioxide and methane has not previously been accounted for and may change the magnitude of the global terrestrial carbon dioxide sink and account of some of the planet’s missing sources of methane. The outcomes of this project will make a significant contribution to our understanding of the global carbon cycle and earth climate system, and inform future management of these systems.

The role of vegetated foreshores in stabilising Australia's shorelines. This project aims to improve Australia's capacity to predict shoreline position with sea level rise, identify the role of vegetation in foreshore stabilisation and determine thresholds for shoreline retreat by quantifying the links between biological, geomorphological and sedimentary processes and shoreline position. Sea level rise and potential increases in storminess are predicted to lead to severe impacts and there is an ....The role of vegetated foreshores in stabilising Australia's shorelines. This project aims to improve Australia's capacity to predict shoreline position with sea level rise, identify the role of vegetation in foreshore stabilisation and determine thresholds for shoreline retreat by quantifying the links between biological, geomorphological and sedimentary processes and shoreline position. Sea level rise and potential increases in storminess are predicted to lead to severe impacts and there is an immediate and critical need to understand and accurately predict the functioning, dynamics, and distribution of Australia's coastal zones. Expected outcomes of this interdisciplinary project include an integrated modelling framework crucial for planning and management of sea level rise responses in Australia.Read moreRead less
Resilience in biogeochemical pathways along a catchment-to-coast continuum. Aquatic systems have degraded more in the past 50 years than any other time in history. Global pressures are further threatening their sustainability, but their complexity makes it difficult to understand how they are responding. This project will combine numerous state-of-the-art approaches to unravel pathways that shape their response.
Controlling cane toads by turning their own weapons against them. This project aims to prevent cane toads, which are causing ecological havoc across tropical Australia, from breeding successfully. Attempts to control toad populations have had little impact, but recent research has revealed a new possibility — exploiting the toads' own weapons for intraspecific conflict. Larval cane toads compete intensely with other larval cane toads and as a result, have evolved a way to kill off their competit ....Controlling cane toads by turning their own weapons against them. This project aims to prevent cane toads, which are causing ecological havoc across tropical Australia, from breeding successfully. Attempts to control toad populations have had little impact, but recent research has revealed a new possibility — exploiting the toads' own weapons for intraspecific conflict. Larval cane toads compete intensely with other larval cane toads and as a result, have evolved a way to kill off their competitors. Toad tadpoles produce chemicals that have devastating effects on younger members of their own species, but not on native species. By deploying those chemicals, this project could develop a novel and powerful form of invader control.Read moreRead less
Ecohydrologic functioning of ephemeral streams. This project aims to increase understanding of how surface-groundwater interactions sustain vegetation associated with ephemeral streams. One of the biggest problems faced by mining and regional development in arid regions is how to protect ecological and heritage values of ephemeral streams by minimising impacts of water abstraction and surplus discharge.

This project aims to increase understanding of how surface-groundwater interactions sustain vegetation associated with ephemeral streams. One of the biggest problems faced by mining and regional development in arid regions is how to protect ecological and heritage values of ephemeral streams by minimising impacts of water abstraction and surplus discharge. The project will use environmental tracers, coupled with assessment of vegetation water use and numerical modelling, to assess resilience of ephemeral streams to changes in flows resulting from mining activities and climate-related shifts in recharge. Expected outcomes of the project include providing appropriate context for evaluating and adapting management to conserve scarce water resources. This project should significantly contribute to the sustainable management of both mineral and groundwater resources.Read moreRead less
