Ants, plants, diversity and function: trophic interactions and ecosystem function in a large-scale restoration experiment. Food and clean water are but two of the benefits we reap from functioning ecosystems, but we know little about how individual species contribute to making ecosystems work. This project capitalises on the diversity of Australia's ant fauna by using ants as a model taxon to explore the link between biodiversity and ecosystem functioning.
The spatial energetics of pollination failure in habitat restoration. This project addresses the reasons for pollination failure of threatened plant species during habitat restoration. Specifically, the project will determine the role of energetic constraints on pollinator movement in the hostile landscape matrix surrounding urban woodland remnants, and model future scenarios for restoring natural functioning woodland ecosystems.
Intervention ecology on coral reefs: a new role for fishes. In a world where few intact reefs remain, the goal of this project is to find ways to restore degraded reefs. Recent research has identified the species responsible for removing harmful algae from coral reefs, while advances in mariculture provide us with the capacity to rear these critically important reef fish species. Combining captive rearing, experimental manipulations, and a global analysis of the functional capacity of herbivorou ....Intervention ecology on coral reefs: a new role for fishes. In a world where few intact reefs remain, the goal of this project is to find ways to restore degraded reefs. Recent research has identified the species responsible for removing harmful algae from coral reefs, while advances in mariculture provide us with the capacity to rear these critically important reef fish species. Combining captive rearing, experimental manipulations, and a global analysis of the functional capacity of herbivorous fishes, in intact, degraded and human-modified systems, the research will explore the potential for restoring, or boosting, the capacity of reefs to withstand disturbance. The goal is to provide the scientific knowledge required to directly modify the key processes operating on coral reefs. Read moreRead less

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

We are in an age of rapid climate change, where the need to understand the adaptive potential of marine organisms in warmer, more acidified oceans is increasingly urgent. This is especially true in Australia where changes are significant. This project uses a cutting-edge, integrated interdisciplinary approach to measure the capacity of oysters to adapt and persist to climate change via transgenerational plasticity, describe the epigenetic mechanisms which underlie it and develop an immediate breeding method to protect vulnerable oysters and other marine organisms against climate change. The research outcomes will transform Indigenous-led oyster reef restoration projects and future-proof an iconic food source and national industry.Read moreRead less
Will trees get enough nitrogen to sustain productivity in elevated CO2? The project proposes to explore how tissue nitrogen declines in future elevated carbon dioxide (eCO2) by studying the availability of soil nitrogen to plants and use of nitrogen by Eucalyptus woodland trees. Plant canopy nitrogen concentrations decline in nearly every large-scale eCO2 study done on native soils. The project plans to explore how changes in ecosystem nitrogen balance occur, by investigating if leaf nitrogen de ....Will trees get enough nitrogen to sustain productivity in elevated CO2? The project proposes to explore how tissue nitrogen declines in future elevated carbon dioxide (eCO2) by studying the availability of soil nitrogen to plants and use of nitrogen by Eucalyptus woodland trees. Plant canopy nitrogen concentrations decline in nearly every large-scale eCO2 study done on native soils. The project plans to explore how changes in ecosystem nitrogen balance occur, by investigating if leaf nitrogen declines under eCO2 due to the balance of plant activity versus changes in soil nitrogen availability. The outcomes are central to knowing the extent to which extra nitrogen ‘feeds’ the eCO2 fertilisation response and sustains long-term increases in productivity. Expected outcomes may support the development of management options to sustain future forest productivity.Read moreRead less
