Maximizing reservoir water quality security through the use of a Lake Diagnostic System (LDS) and a Controlled Lagrangian Drogue (CLD). It is proposed to build on recent advancements in limnological research and existing measurement technologies to develop the hardware, algorithms and software to form a unique real time reservoir water quality management system, driven by minimal measurement inputs. This will remove the reliance on extensive expensive reservoir monitoring, previously necessary ....Maximizing reservoir water quality security through the use of a Lake Diagnostic System (LDS) and a Controlled Lagrangian Drogue (CLD). It is proposed to build on recent advancements in limnological research and existing measurement technologies to develop the hardware, algorithms and software to form a unique real time reservoir water quality management system, driven by minimal measurement inputs. This will remove the reliance on extensive expensive reservoir monitoring, previously necessary to characterize the lake spatial variability and seasonality, for full 3D modelling. This project will deliver to industry: two measurement tools to simplify reservoir monitoring, the LDS and CLD; and software tools to manage real time data collection, provide decision support to reservoir managers and to enable ?on-demand? scenario predictions.Read moreRead less
Between a hot place & hypoxia: Quantifying fish-kill risk in inland rivers. Native fish populations in Australian ephemeral rivers are highly valued but are subject to widespread decline. During drought waterholes serve as critical refuges for native fish, however thermal extremes and hypoxia (lack of oxygen) have led to regular fish-kill events. Whilst we know the general conditions that lead to fish-kills, we do not have a clear understanding of why some species are more tolerant than others, ....Between a hot place & hypoxia: Quantifying fish-kill risk in inland rivers. Native fish populations in Australian ephemeral rivers are highly valued but are subject to widespread decline. During drought waterholes serve as critical refuges for native fish, however thermal extremes and hypoxia (lack of oxygen) have led to regular fish-kill events. Whilst we know the general conditions that lead to fish-kills, we do not have a clear understanding of why some species are more tolerant than others, or how we can help decision-makers anticipate fish-kill risks. This project will combine laboratory ecophysiology investigations and novel field monitoring techniques to develop a next-generation fish habitat model for stakeholders to use to assess fish-kill risks and plan for restoration.

Mining, irrigation, and groundwater: Towards a reliable protocol for assessing the impacts of extraction on groundwater fauna and ecology. Groundwater fluctuations associated with mining and increased irrigation demands, potentially threaten many of Australia's unique groundwater invertebrates (stygofauna) with extinction. Stygofauna represent a hidden store of biodiversity and are thought to have a critical, but poorly understood, role in enhancing groundwater quality. Environmentally sustainab ....Mining, irrigation, and groundwater: Towards a reliable protocol for assessing the impacts of extraction on groundwater fauna and ecology. Groundwater fluctuations associated with mining and increased irrigation demands, potentially threaten many of Australia's unique groundwater invertebrates (stygofauna) with extinction. Stygofauna represent a hidden store of biodiversity and are thought to have a critical, but poorly understood, role in enhancing groundwater quality. Environmentally sustainable development of groundwater resources is hampered by a dearth of information on the ecological needs of stygofauna and how they respond to human-induced change. Using field and laboratory experiments, we aim to determine how water table fluctuations threaten stygofauna. From our results we will develop sampling and management protocols to monitor and protect stygofauna communities.Read moreRead less
Ecological responses of native fishes to dynamic water flows in northwest arid Australia. This project will investigate the biological adaptations and ecology of native fishes of northwest Australia in order to assess their resilience to altered water flows due to mining activities and changing climate. The project findings will contribute to sustainable management of water and biodiversity in arid environments.
Forecasting fish resilience to environmental change in northern Australia. This project aims to use a traits-based modelling framework, incorporating variability both within and between species, to forecast the resilience of freshwater fishes in northern Australia to impending environmental change. While northern Australian rivers are among the most pristine and productive on earth, they face profound change due to human activity. Emerging evidence suggests that flexibility in functional traits ....Forecasting fish resilience to environmental change in northern Australia. This project aims to use a traits-based modelling framework, incorporating variability both within and between species, to forecast the resilience of freshwater fishes in northern Australia to impending environmental change. While northern Australian rivers are among the most pristine and productive on earth, they face profound change due to human activity. Emerging evidence suggests that flexibility in functional traits (e.g. life history, physiology, behaviour, diet) may result in resilience to environmental change. This project aims to provide decision-makers with essential information and new tools to underpin future planning and resource management.Read moreRead less
Subterranean invertebrate communities of arid zone Western Australia: diversity, assessment and food-web structure. The diverse and unique subterranean fauna associated with aquifers of the Western Australia arid zone is potentially threatened by water extraction, mining and other human impacts. This project aims to apply a powerful combination of molecular genetic analyses and compound specific isotope analyses to study, for the first time, the food web structure and source of energy of these g ....Subterranean invertebrate communities of arid zone Western Australia: diversity, assessment and food-web structure. The diverse and unique subterranean fauna associated with aquifers of the Western Australia arid zone is potentially threatened by water extraction, mining and other human impacts. This project aims to apply a powerful combination of molecular genetic analyses and compound specific isotope analyses to study, for the first time, the food web structure and source of energy of these groundwater ecosystems. The project aims to also develop novel procedures for monitoring their biodiversity using environmental DNA within the groundwater. The results will provide crucial information for the management of groundwater, and conservation of their associated ecosystems, and significantly improve the rigour of long-term environmental monitoring.Read moreRead less
Resilience of lake ecosystems to water-level manipulation. Which lakes recover from fluctuations in water level and which do not? Manipulations of water levels in lakes will need to intensify as droughts become more frequent. This project will develop robust ways of forecasting how lakes will respond to changes in manipulations of water levels, to minimise extinctions and maintain aesthetics and water quality.
