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
Quantitative metrics for determining aquifer ecosystem state. Clean groundwater comes from dirty surface water by way of biological purification. This project will develop quantitative ways to assess groundwater ecosystems to ensure the sustainable extraction of water and maintenance of these crucial ecosystems.

Summary
Mechanisms underlying crop pollinator effectiveness in agro-ecosystems. This project aims to understand how pollinators affect fruit quantity and quality. Worldwide, insect pollinators contribute to biodiversity and ecosystem services in production systems, but also cause yield variability in pollinator-dependent crops. Accounting for the combined outcomes of the amount, quality and timing of the pollen transferred by each pollinator visit is a critical but unexplored component of crop pollinati ....Mechanisms underlying crop pollinator effectiveness in agro-ecosystems. This project aims to understand how pollinators affect fruit quantity and quality. Worldwide, insect pollinators contribute to biodiversity and ecosystem services in production systems, but also cause yield variability in pollinator-dependent crops. Accounting for the combined outcomes of the amount, quality and timing of the pollen transferred by each pollinator visit is a critical but unexplored component of crop pollination ecology. This project will quantitatively assess the effectiveness of pollinator communities to determine the importance of pollinator community composition to maximising crop production. This project is expected to protect food resources and economically benefit Australia.Read moreRead less
Red listing ecosystems - testing the new global standard for conservation. The International Union for Conservation of Nature (IUCN) Red Lists are critical for setting conservation priorities. These include a well-tested species Red List protocol, and a new global standard for Red-listing ecosystems. This project will test the new global standard across a range of marine, terrestrial and freshwater ecosystems, developing powerful new tools and guidelines for application.

Summary
Forecasting ecosystem collapse and recovery by tracking networks of species. This project aims to assess and predict ecosystem decline by measuring change in networks of interacting species. Efforts to prevent ecosystem collapse are failing. A focus on managing individual species ignores the fact that ecosystems function because species have complex associations with one another and the environment. This project will use methods from social networks, food-web theory and web-searching behaviour, ....Forecasting ecosystem collapse and recovery by tracking networks of species. This project aims to assess and predict ecosystem decline by measuring change in networks of interacting species. Efforts to prevent ecosystem collapse are failing. A focus on managing individual species ignores the fact that ecosystems function because species have complex associations with one another and the environment. This project will use methods from social networks, food-web theory and web-searching behaviour, to discover symptoms of declining ecosystems and find robust metrics that diagnose change in networks of co-occurring species. The intended outcome is to clarify the relationship between species interactions, co-occurrence and ecosystem decline, knowledge critical to ecosystem recovery.Read moreRead less

Cyanobacterial bio-encapsulation for restoring degraded drylands. This project aims to discover the ecological and functional roles of cyanobacteria in drylands, and develop new technologies for their broad application in large-scale ecosystem restoration. The global demand for landscape-scale restoration requires novel approaches to deliver on the promise of reinstating healthy, sustainable, and biodiverse ecosystems. This project will harness next-generation DNA sequencing to select beneficial ....Cyanobacterial bio-encapsulation for restoring degraded drylands. This project aims to discover the ecological and functional roles of cyanobacteria in drylands, and develop new technologies for their broad application in large-scale ecosystem restoration. The global demand for landscape-scale restoration requires novel approaches to deliver on the promise of reinstating healthy, sustainable, and biodiverse ecosystems. This project will harness next-generation DNA sequencing to select beneficial cyanobacteria for incorporation into emerging seed enhancement technologies. The project will deliver innovative and cost-effective tools to overcome barriers to seedling recruitment and plant survival, and enhance the functionality of degraded dryland ecosystems. This will contribute to long-term cost savings to the Australian economy through reduced spending on environmental issues such as salinity, erosion, acidification and poor water quality.Read moreRead less
Predicting the delivery of ecosystem services in agricultural landscapes. The ecological sustainability of Australian agriculture relies on services (for example, pollination) provided by ecosystems. Service provision is threatened by environmental change, but there is no established approach for predicting the impact of change on services.

The ecological sustainability of Australian agriculture relies on services (for example, pollination) provided by ecosystems. Service provision is threatened by environmental change, but there is no established approach for predicting the impact of change on services. This project will undertake the most comprehensive experimental examination of ecosystem-service delivery ever conducted in Australia, testing the predictive capacity of an approach that links environmental change with variation in service provision through species’ traits. The major outcomes include greater capacity for agriculturalists to maximise ecosystem benefits and increase economic returns, and improved biodiversity conservation through recognition of its contribution to agriculture.

Testing the importance of large-scale climate factors to plant community assembly following land-use change. This project will examine the native plant species and functional diversity of Australia's rain forest communities to create a predictive framework of how plant communities recover following deforestation. Such a framework is key to focusing conservation efforts in degraded and multi-use landscapes.
Dynamic resilience and stability properties of marine systems: the importance of environment-engineer feedbacks in kelp forests. Kelp forests form complex habitats that support diverse, productive and economically important food-webs. This project will determine whether healthy kelp forests engineer their environment to make conditions more suitable for their continued recruitment and survivorship, thus increasing their stability and resilience in response to anthropogenic threats.
