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

This project aims to investigate the capacity of farm dam management strategies to simultaneously support nature conservation and agricultural production. The project expects to generate new knowledge in the areas of conservation biology and sustainable agriculture by using experiments that identify the interdependence of cattle grazing and habitat quality of wetlands. Anticipated outcomes include a framework for evaluating management strategies in terms of their dual capacity to support aquatic wildlife and livestock production. Significant benefits include increased productivity through the improved management of wetlands and dams on farms and the recogniton of undervalued conservation resources.Read moreRead less
Have we already lost the Australian lungfish? This project aims to use radiocarbon ageing, conservation genetics and modelling to identify threats to the long-term survival of the Australian lungfish, the world's oldest living vertebrate. This project will provide managers with a powerful tool to prioritise management interventions to ensure the conservation of the species and to pull it back from extinction.

Understanding infection tolerance to improve management of wildlife disease. This project aims to investigate tolerance (the ability to limit the detrimental effects of infection) as a key animal defence strategy against disease. It focuses on diseases in natural systems, using the devastating amphibian fungal skin disease, chytridiomycosis, as a model. Expected outcomes include improved understanding of the relative importance of tolerance and resistance, and insight into the key immune and phy ....Understanding infection tolerance to improve management of wildlife disease. This project aims to investigate tolerance (the ability to limit the detrimental effects of infection) as a key animal defence strategy against disease. It focuses on diseases in natural systems, using the devastating amphibian fungal skin disease, chytridiomycosis, as a model. Expected outcomes include improved understanding of the relative importance of tolerance and resistance, and insight into the key immune and physiologic mechanisms underlying variations in tolerance. Anticipated benefits include improved strategies for mitigating infectious wildlife diseases via identifying targets for therapeutic interventions, ecological management and assisted-evolution strategies. This project should also benefit amphibian conservation globally.Read moreRead less

Summary
Planning for rare aquatic species: conservation and restoration priorities at local and continental scales. This project will develop a new method to include rare species in conservation plans by identifying habitat characteristics that are responsible for their distribution. After establishing these relations, cost-effective conservation and restoration actions will target rare fish, waterbird and insect species in Australian and overseas rivers.
Systematic planning beyond conservation: a multi-objective, multi action framework for sustainable biodiversity. When planning for conservation in rivers, protecting plants and animals can not simply be achieved by protecting parts of a river. This project will develop a strategy to sustain freshwater biodiversity that will optimally allocate conservation and restoration resources and minimises negative socioeconomic impacts on stakeholders.
Designing effective fish-friendly waterway culverts: integration of hydrodynamics and swimming performance. Man-made in-stream structures (for example, dams and road crossings) have contributed to major declines in native fish numbers, with more than 6,000 barriers to fish migration occurring in New South Wales alone. Recognising this, Fisheries New South Wales led the development of national guidelines for the design and construction of fish friendly road crossings. Unfortunately, these guideli ....Designing effective fish-friendly waterway culverts: integration of hydrodynamics and swimming performance. Man-made in-stream structures (for example, dams and road crossings) have contributed to major declines in native fish numbers, with more than 6,000 barriers to fish migration occurring in New South Wales alone. Recognising this, Fisheries New South Wales led the development of national guidelines for the design and construction of fish friendly road crossings. Unfortunately, these guidelines have little empirical backing. This project will integrate data on the swimming ability of Australian fish species with culvert hydrodynamic modelling to better understand fish requirements in and around road crossings. These data will strengthen national design guidelines and provide the tools engineers and planners need to balance fish migration with effective water management.Read moreRead less
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
How will the biodiversity crisis affect vital ecosystem functions? Loss of biodiversity due to environmental change is a potentially serious issue for the sustainability of ecosystems. Predictions on how biodiversity loss will affect ecosystem functions and services require a well-developed understanding of its effects on plant litter decomposition, because this process is a key component of the global carbon cycle. This project will advance this understanding by addressing several key questions ....How will the biodiversity crisis affect vital ecosystem functions? Loss of biodiversity due to environmental change is a potentially serious issue for the sustainability of ecosystems. Predictions on how biodiversity loss will affect ecosystem functions and services require a well-developed understanding of its effects on plant litter decomposition, because this process is a key component of the global carbon cycle. This project will advance this understanding by addressing several key questions (for example, relative importance of decomposition versus other drivers of environmental change; and temporal variation in biodiversity effects on decomposition), using forest streams as model systems. These experiments will mimic realistic extinction events across climatic gradients, enabling predictions to be made at large scales.Read moreRead less
