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
Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years.

The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will be combined with isotopic analysis to reveal how environmental and biological factors drive animal movements and impact habitat connectivity. In a world of vanishing top predators, it is imperative to understand system dynamics before we can evaluate the impact of species removal on ecosystem function.Read moreRead less

Mechanistic investigation of fluorinated coatings for stone preservation. We will investigate mechanisms governing the synthesis of a latex used for stone preservation. This latex is made from novel and unusual starting materials, and will be the most complex system for which mechanisms have been investigated. We will redesign the synthesis procedure to control particle size and composition of the functional species at the particle surface. This will enable both particle size and surface composi ....Mechanistic investigation of fluorinated coatings for stone preservation. We will investigate mechanisms governing the synthesis of a latex used for stone preservation. This latex is made from novel and unusual starting materials, and will be the most complex system for which mechanisms have been investigated. We will redesign the synthesis procedure to control particle size and composition of the functional species at the particle surface. This will enable both particle size and surface composition to be tailored as desired. The results will be used to investigate the influence of these quantities on interactions between particles and sandstone surfaces. The outcomes will be used by the industrial partner to devise improved protective coatings for stone surfaces in Australian conditions.Read moreRead less
Resolving nitrogen and phosphorus transformations along subterranean estuary - sediment/water interface continuums in carbonate sands. Humans are modifying global nitrogen (N) and phosphorus (P) cycles at an alarming rate. The release of N and P into the environment drives eutrophication, one of the greatest threats to coastal ecosystems worldwide. Globally, there is little effort being made to control increasing N and P emissions. The transport of contaminated groundwater is a major source of N ....Resolving nitrogen and phosphorus transformations along subterranean estuary - sediment/water interface continuums in carbonate sands. Humans are modifying global nitrogen (N) and phosphorus (P) cycles at an alarming rate. The release of N and P into the environment drives eutrophication, one of the greatest threats to coastal ecosystems worldwide. Globally, there is little effort being made to control increasing N and P emissions. The transport of contaminated groundwater is a major source of N and P to the coastal zone and an overlooked driver of eutrophication. Yet, research into the processes that influence N and P transformation in groundwater are scarce, they neglect carbonate sand systems and have ignored the processes in key groundwater transition zones. This project will generate new knowledge that will help us understand the role that groundwater plays in coastal eutrophication.Read moreRead less
Effect of cane sugar juice composition on scaling rate and scale composition in sugar mills. The Australia sugar industry produces 1100 GWh of renewable electricity annually, abating ~1.1 M tonnes of CO2-equivalent of greenhouse gases. This can be increased if the juice evaporation performance, which largely determines the energy efficiency of the sugar factory, can be improved through reduced fouling of evaporators. This project will investigate the effect of juice composition on fouling of sug ....Effect of cane sugar juice composition on scaling rate and scale composition in sugar mills. The Australia sugar industry produces 1100 GWh of renewable electricity annually, abating ~1.1 M tonnes of CO2-equivalent of greenhouse gases. This can be increased if the juice evaporation performance, which largely determines the energy efficiency of the sugar factory, can be improved through reduced fouling of evaporators. This project will investigate the effect of juice composition on fouling of sugar factory evaporators so that a model to predict scale type and scale propensity can be developed. This will enable the development of better scale control strategies, resulting in reduced energy usage and reduced usage of the hazardous and polluting chemicals required to remove scale.Read moreRead less

Innovative tools needed for market-based nutrient offsetting . This project will apply innovative approaches to develop a functional equivalency of nutrients from catchment versus point sources. This is fundamental knowledge needed for the successful application of nutrient offsetting. This market-based mechanism involves point source polluters choosing to pay for catchment restoration, which is offset against their nutrient discharge. Currently, despite its potential, there is a lack of confide ....Innovative tools needed for market-based nutrient offsetting . This project will apply innovative approaches to develop a functional equivalency of nutrients from catchment versus point sources. This is fundamental knowledge needed for the successful application of nutrient offsetting. This market-based mechanism involves point source polluters choosing to pay for catchment restoration, which is offset against their nutrient discharge. Currently, despite its potential, there is a lack of confidence in the scientific robustness of nutrient offsetting. The proposed new indicators in nutrient equivalency would provide the foundation needed to ensure that governments and industry can have the confidence to engage in nutrient trading schemes, ultimately ensuring environmental and social benefits.Read moreRead less
Adaptive ecotyping of the toxic cyanobacterium Cylindrospermopsis raciborskii to predict its invasive capacity. We change the world while other organisms adapt to these new conditions. Cyanobacteria (blue green algae) increasingly dominate water bodies that were previously free of these harmful blooms. To minimise the spread of these algae, this project will study the genetic basis that determines how rapidly they can evolve and adapt to a changing planet.
