Reimagining the Australian Suburb: Biodiversity planning in urban fringe landscapes. Over 40% of nationally listed threatened ecological communities occur in urban areas. Accelerating urbanisation in Australia is considered one of the greatest threats to biodiversity. This threat will increase without a more strategic approach to conservation planning in urban environments.

Over 40% of nationally listed threatened ecological communities occur in urban areas. Accelerating urbanisation in Australia is considered one of the greatest threats to biodiversity. This threat will increase without a more strategic approach to conservation planning in urban environments. Protection of biodiversity in urban areas brings numerous societal benefits but involves complicated tradeoffs between competing land uses including housing development, agricultural production and conservation. This project builds on recent advancements in ecological modelling and mathematical optimisation to develop and test tools to facilitate transparent decisions based on optimal trade-offs between competing values. It will result in a more strategic approach to planning conservation in urban environments.Read moreRead less
Practical, powerful and cost effective indicators of sustainable forest management for the conservation of biological diversity. Much debate about appropriate use of Australia's forests stems from uncertainty about the magnitude of impacts on abundances and distributions of forest-dependent species, a key indicator of sustainable management under the Montreal Process. An opportunity exists to develop new tools to substantially improve our ability to detect and assess change. This project will de ....Practical, powerful and cost effective indicators of sustainable forest management for the conservation of biological diversity. Much debate about appropriate use of Australia's forests stems from uncertainty about the magnitude of impacts on abundances and distributions of forest-dependent species, a key indicator of sustainable management under the Montreal Process. An opportunity exists to develop new tools to substantially improve our ability to detect and assess change. This project will develop optimal monitoring design and analysis strategies for detecting population trends against a background of natural fluctuation and observation error. It will result in templates for coherent reporting on indicators at regional and national levels. It will exploit recent findings regarding observation error in surveys, advances in statistical control processes, simulation methods, and power analysis to develop a world-class species monitoring system.Read moreRead less
Drought and Salinity Tolerance in Metal Hyperaccumulating Plants: A Functional Role for the Metals? A few plant species can ?hyperaccumulate? metal ions to 100-1000 times the concentrations seen in ?normal? plants. Just why these plants have evolved such an extreme response to metalliferous soils remains an enigma. Many of the hyperaccumulators so far described are endemic to xeric environments, or saline soils prone to rapid drying. We hypothesize that the metals might act as osmotica, enha ....Drought and Salinity Tolerance in Metal Hyperaccumulating Plants: A Functional Role for the Metals? A few plant species can ?hyperaccumulate? metal ions to 100-1000 times the concentrations seen in ?normal? plants. Just why these plants have evolved such an extreme response to metalliferous soils remains an enigma. Many of the hyperaccumulators so far described are endemic to xeric environments, or saline soils prone to rapid drying. We hypothesize that the metals might act as osmotica, enhancing plant survival during water stress. This will be tested for Australian native and non-native hyperaccumulator plants. The study will clarify our understanding of the evolutionary significance of hyperaccumulation, and has important applications for extracting metals from contaminated soils.Read moreRead less

This project is a world-first, catchment-scale, experimental test of the benefits of new stormwater treatment approaches to stream health. The project, a collaboration with Melbourne Water and the Shire of Yarra Ranges, integrates river, urban stormwater and water resource management for multiple benefits. It should accelerate the uptake of smart, sustainable technologies in stormwater use and management, and identify better investment strategies for urban water and river management. The robust testing of the effect of new treatment design objectives by a catchment-scale experiment will have a strong impact on research in stream ecology and urban water management.Read moreRead less
Understanding coastal biodiversity: The impact of marine production subsidies upon arid coastal environments. Many of the Earth's coastlines have productive seas next to arid terrestrial habitats. Much of the coastline of Western Australia is arid. Our project will determine if biodiversity in fringing terrestrial areas is controlled by the supply of marine plant material that is transported to land by waves, wind and birds. A consequence of increasing coastal usage is associated growing anthrop ....Understanding coastal biodiversity: The impact of marine production subsidies upon arid coastal environments. Many of the Earth's coastlines have productive seas next to arid terrestrial habitats. Much of the coastline of Western Australia is arid. Our project will determine if biodiversity in fringing terrestrial areas is controlled by the supply of marine plant material that is transported to land by waves, wind and birds. A consequence of increasing coastal usage is associated growing anthropogenic pressures on the coastal environment. Our aim is to enhance awareness of the interactions that occur between terrestrial and marine systems, and hence to increase the capacity of the public and private sector to manage marine and terrestrial ecosystems, and the interface between them.Read moreRead less

This project will use DNA data to address fundamental questions about the origin and maintenance of biodiversity in a popular and widely distributed fish group. From a conservation perspective, the project will produce a benchmark about management of fish resources. We will investigate questions related to important conservation issues (including the recovery plan of a nationally threatened species) and the management of stocking activities in recreational fisheries of coastal and inland waters. The latter is particularly relevant to rural communities since they provide both social and economic benefits to rural people.Read moreRead less
High temperature limits of leaf function. In arid and semi-arid central Australia, Acacia spp. dominate the over-storey, but this shifts to Eucalyptus and Corymbia spp. in more mesic coastal regions. Areas of central Australia are extremely hot, dry and sunny, and it is this combination of stresses that likely excludes Eucalyptus spp. from many landforms. There has been little research on high temperature tolerance of Acacia and Eucalyptus, despite the putative importance of this stress, in co ....High temperature limits of leaf function. In arid and semi-arid central Australia, Acacia spp. dominate the over-storey, but this shifts to Eucalyptus and Corymbia spp. in more mesic coastal regions. Areas of central Australia are extremely hot, dry and sunny, and it is this combination of stresses that likely excludes Eucalyptus spp. from many landforms. There has been little research on high temperature tolerance of Acacia and Eucalyptus, despite the putative importance of this stress, in combination with other stresses, in limiting species? distributions. Our program of collaborative research will examine the tolerance of Acacia and Eucalyptus to a combination of high temperatures, drought and high light.Read moreRead less
A new hypothesis for the development of hollows in Box-Ironbark forest. Timber harvesting in Box-Ironbark forest over the past 150 years has significantly affected the habitat of hollow dependent fauna. Current management aims at speeding the growth of trees to accelerate hollow formation. Recent studies suggest that hollows form in trees of the Box-Ironbark forest following basal stem damage by fire or windstorm, rather than from branch damage as previously assumed. This hypothesis will be t ....A new hypothesis for the development of hollows in Box-Ironbark forest. Timber harvesting in Box-Ironbark forest over the past 150 years has significantly affected the habitat of hollow dependent fauna. Current management aims at speeding the growth of trees to accelerate hollow formation. Recent studies suggest that hollows form in trees of the Box-Ironbark forest following basal stem damage by fire or windstorm, rather than from branch damage as previously assumed. This hypothesis will be tested in relation to wildfires in 1985, 1991 and 1993 and by experimental simulation of these events. The results of this research are likely to have major implications for the management of Box- Ironbark forests.Read moreRead less
How connected are marine populations? Comparing life histories of endemic and non-endemic reef fishes to investigate the mechanisms behind self-recruitment. Recruitment of pelagic larvae plays a fundamental role in benthic marine populations, yet the sources and destinations of recruits are unknown for nearly all marine species. Because endemic species rely on retention of locally spawned larvae, they provide a novel opportunity for investigating the mechanisms allowing self-recruitment. I prop ....How connected are marine populations? Comparing life histories of endemic and non-endemic reef fishes to investigate the mechanisms behind self-recruitment. Recruitment of pelagic larvae plays a fundamental role in benthic marine populations, yet the sources and destinations of recruits are unknown for nearly all marine species. Because endemic species rely on retention of locally spawned larvae, they provide a novel opportunity for investigating the mechanisms allowing self-recruitment. I propose to compare the life histories and microchemical signatures in larval otoliths of endemic and closely related non-endemic reef fishes to determine the mechanisms and prevalence of self-recruitment. The results will broaden our understanding of how marine populations are replenished, information critically needed for marine conservation and resource management.Read moreRead less
