A new integrated approach for ecologically sustainable forest management. As harvested regions can maintain high levels of biodiversity, forestry has moved away from conservation in large reserves, and instead focuses on creating a dynamic mosaic of harvested and unharvested forest. However, designing this mosaic poses complex problems.

As harvested regions can maintain high levels of biodiversity, forestry has moved away from conservation in large reserves, and instead focuses on creating a dynamic mosaic of harvested and unharvested forest. However, designing this mosaic poses complex problems. This project aims to identify underlying patterns and processes determining how forest biodiversity is distributed and use this information to develop decision models to underpin sustainable forest management plans. Existing and new evidence will be used, the latter derived from three innovative approaches for more efficient and cost effective biodiversity assessment: remote sensing of plants, next generation DNA technology of beetles and analysis of acoustic recording of birds.Read moreRead less
Optimising biodiversity conservation in managed forest landscapes. How to meet human needs for timber while limiting harm to biodiversity is an urgent scientific goal. The project will address this challenge by quantifying the impacts of forestry systems and wildfire on mammal species. Novel network modelling of interactions among plants, animals, and environmental variables will establish cost-effective management improvements to maximise biodiversity values. A systematic conservation planning ....Optimising biodiversity conservation in managed forest landscapes. How to meet human needs for timber while limiting harm to biodiversity is an urgent scientific goal. The project will address this challenge by quantifying the impacts of forestry systems and wildfire on mammal species. Novel network modelling of interactions among plants, animals, and environmental variables will establish cost-effective management improvements to maximise biodiversity values. A systematic conservation planning approach will deliver spatially and temporally explicit solutions to balancing trade-offs between production and conservation taking into account dynamic impacts from climate change and fire. Outcomes will provide a foundation for policy changes to put theoretical solutions into practice.Read moreRead less
Conserving biodiversity in timber production forests. Intensified forestry to meet rising demand for timber is placing biodiversity at risk. The aim of this project is to develop and field-test a novel framework to reconcile forest conservation with production. The project seeks to resolve whether intensive forestry coupled with a large reserve network produces better biodiversity outcomes than less intensive forestry with fewer reserves. I will integrate abundances of plant and animal species w ....Conserving biodiversity in timber production forests. Intensified forestry to meet rising demand for timber is placing biodiversity at risk. The aim of this project is to develop and field-test a novel framework to reconcile forest conservation with production. The project seeks to resolve whether intensive forestry coupled with a large reserve network produces better biodiversity outcomes than less intensive forestry with fewer reserves. I will integrate abundances of plant and animal species with forest industry timber yield data in a uniquely suited landscape. Survey results will be synthesised with global data on biodiversity responses to forestry. This research will benefit the forest industry by providing guidelines that improve conservation outcomes while maintaining timber yield.Read moreRead less
Developing DNA tracking methods to identify illegally logged timber products from Africa. Illegal logging causes societal and environmental forest degradation, and is a high priority for international control. This project will produce a range of DNA methods that allow the tracing of the geographic source of origin for timber products from African tropical forests that will allow producers and consumers to better market and choose their products.
Understanding the underlying causes and practical management solutions to marri (Corymbia calophylla) decline in the south west of Western Australia. Tree declines threaten forests across much of Australia and efficient methods to understand and manage the causes are urgently needed. We will test a step-wise multidisciplinary model to determine the causes of marri (Corymbia calophylla) decline, which is currently threatening important ecosystem functions and biodiversity.
Carboxylate exudation and phosphorus acquisition in eucalypts. Eucalypts are thought to rely on mycorrhizas to acquire phosphorus (P). Using leaf manganese concentrations in the field to proxy rhizosphere carboxylates, followed by plant growth in low P-solutions, it was shown that some, but not all eucalypts that grow on P-impoverished soils release carboxylates from their roots. This trait is a strategy of Proteaceae to access soil P, but assumed not to be used by eucalypts. This game-changing ....Carboxylate exudation and phosphorus acquisition in eucalypts. Eucalypts are thought to rely on mycorrhizas to acquire phosphorus (P). Using leaf manganese concentrations in the field to proxy rhizosphere carboxylates, followed by plant growth in low P-solutions, it was shown that some, but not all eucalypts that grow on P-impoverished soils release carboxylates from their roots. This trait is a strategy of Proteaceae to access soil P, but assumed not to be used by eucalypts. This game-changing discovery challenges the current dogma that eucalypts invariably rely on mycorrhizas to acquire P. This project will explore the significance of this newly-described trait for functioning of eucalypts more broadly and produce results that are important for conservation, restoration and forestry activities.

To grow or to store: Do plants hedge their bets? This project aims to resolve a long-standing question about the function of perennial plants: how much of the carbon taken up by photosynthesis is used immediately for growth, and how much is kept in reserve as insurance against future stress? This question is important to our understanding of how plants respond to stresses such as severe drought, and yet lack of data and theoretical modelling currently hampers our ability to answer it.

This project aims to resolve a long-standing question about the function of perennial plants: how much of the carbon taken up by photosynthesis is used immediately for growth, and how much is kept in reserve as insurance against future stress? This question is important to our understanding of how plants respond to stresses such as severe drought, and yet lack of data and theoretical modelling currently hampers our ability to answer it. By applying novel data analysis and modelling tools to recent experimental results, the project plans to test hypotheses for how plants allocate carbon between growth and storage in response to stress. Insights from the project may underpin better management of Australia’s vulnerable ecosystems.Read moreRead less

Summary
High-throughput sample preparation robotics to enable emerging large-scale plant genomics, metabolomics and proteomics research. Discovering and breeding plants that are best suited for new environmental conditions requires the analysis of many samples to discover the underlying genes, metabolites and proteins. The project will build two robotic instruments that will facilitate the rapid grinding and extraction of plant tissues to facilitate these discoveries across Australia.
Disentangling climate and evolutionary controls over the temperature dependence of leaf respiration. The project will use field and laboratory studies to establish if there are systematic differences in the temperature responses of leaf respiration in plants adapted to hot and cold environments. The results will enable climate modellers to better predict impacts of climate change on carbon exchange between vegetation and the atmosphere.
A step change in modeling leaf respiration-photosynthesis relationships . This project aims to use innovative, high-throughput technologies to develop a novel framework that links daytime photosynthesis and starch/amino acid mobilisation to variations in night-time leaf respiration. Variations in leaf respiration can have large impacts on ecosystem functioning and the Earth’s climate. Although advances have been made in respiration modelling, current models are unable to predict dynamic, day-to- ....A step change in modeling leaf respiration-photosynthesis relationships . This project aims to use innovative, high-throughput technologies to develop a novel framework that links daytime photosynthesis and starch/amino acid mobilisation to variations in night-time leaf respiration. Variations in leaf respiration can have large impacts on ecosystem functioning and the Earth’s climate. Although advances have been made in respiration modelling, current models are unable to predict dynamic, day-to-day variations in respiratory rates. Expected outcomes include equations that predict daily variations in night-time leaf respiration for environments across Australia and overseas. Benefits to planners include the ability to more accurately model vegetation-atmosphere carbon exchange and future changes in climate. Read moreRead less
