Comparative ecology of common and threatened plants in fire-prone habitats. There is a critical lack of data on the fire responses of many threatened plant species in Australia, yet such information is essential for species recovery planning and land management. This project will use plants in the Family Epacridaceae (the heaths) as a case study to test whether particular plant traits are associated with rarity vs commonness in fire prone habitats of south eastern Australia. The results will in ....Comparative ecology of common and threatened plants in fire-prone habitats. There is a critical lack of data on the fire responses of many threatened plant species in Australia, yet such information is essential for species recovery planning and land management. This project will use plants in the Family Epacridaceae (the heaths) as a case study to test whether particular plant traits are associated with rarity vs commonness in fire prone habitats of south eastern Australia. The results will increase knowledge of the ecology of this particular, under-studied plant group and will also enable the development of ecologically sound fire management practices, especially in relation to threatened species.Read moreRead less
Establishing baseline ecological conditions for the Lower Lakes, South Australia: the applications of palaeoecology to sustainable resource management. The Lower Lakes of the Murray River are in a critical ecological state due to record low water levels. Management of these lakes needs to integrate water security demands with maintaining healthy ecosystem functions. Proposed management options such as allowing seawater incursion and the construction of a weir to impede freshwater flows are based ....Establishing baseline ecological conditions for the Lower Lakes, South Australia: the applications of palaeoecology to sustainable resource management. The Lower Lakes of the Murray River are in a critical ecological state due to record low water levels. Management of these lakes needs to integrate water security demands with maintaining healthy ecosystem functions. Proposed management options such as allowing seawater incursion and the construction of a weir to impede freshwater flows are based on assumptions about what the Lakes were like naturally (pre-European). This study will reconstruct environmental variability within the Lower Lakes over the past 7000 years, concentrating on salinity to document the extent of marine incursion, and pH to examine the impacts of acid sulphate release from exposed sediments during low flow events.

The highly prized sandalwood is the basis of an industry that employs over 100 people and generates $12 million export income annually in regional WA. Natural recruitment of sandalwood is poor. This project will build on research, conducted by Murdoch University and the Forest Products Commission, that indicates natural recruitment of the tree is greatly enhance in the presence of native rat-kangaroos who cache the seeds. This project will train an APA(I) postgraduate through an industry based project that will evaluate increased recruitment of sandalwood by native mammal caching. Many of these mammals are Conservation Dependent or Threatened with extinction.Read moreRead less

Coral Reef Fishes And The Global Decline In Reef Health: Is Biodiversity At Risk Or Resilient? Successful management and protection of marine species depends on understanding the processes that control the biodiversity of marine communities at both local and regional scales. This study will develop a general model to predict the response of reef fish communities to declining habitat structure and diversity across the tropical Pacific Ocean. Using expertise and ecological tools developed in Austr ....Coral Reef Fishes And The Global Decline In Reef Health: Is Biodiversity At Risk Or Resilient? Successful management and protection of marine species depends on understanding the processes that control the biodiversity of marine communities at both local and regional scales. This study will develop a general model to predict the response of reef fish communities to declining habitat structure and diversity across the tropical Pacific Ocean. Using expertise and ecological tools developed in Australia, and in collaboration with scientists working on the other side of the Pacific, this project will develop a broad-scale understanding of the threats to coral reefs and play a leading role in the development of marine-biodiversity management plans for Australia and neighbouring regions.Read moreRead less
Building capacity for adaptive management in protected areas through improved systems for monitoring and evaluation. The project demonstrates how evaluation can lead to improved management of protected areas. Effectively managed protected areas are essential for biodiversity conservation.

The project demonstrates how evaluation can lead to improved management of protected areas. Effectively managed protected areas are essential for biodiversity conservation. Improved management, and hence improved conservation outcomes will flow from enhanced use of monitoring and evaluation data in decision-making. Identifying strengths and weaknesses in management will allow managers to better allocate resource for more effective conservation outcomes. The project establishes connections with all protected area management agencies in Australia, and will contribute to the development of national policy and practice in protected area evaluation and reporting, thus helping to meet national and international reporting obligations.

Evaluating the influence of trophic connections between marine habitats on the effectiveness of Marine Protected Areas. Marine ecosystems are characterized by trophic subsidies: consumers forage between habitats, and ungrazed primary production is exported as drift or detritus. However, the trophic relationships we see today may in a sense be unnatural, because intensive fishing of consumers may have fundamentally altered them.
We aim to evaluate the importance of the exchange of consumers and ....Evaluating the influence of trophic connections between marine habitats on the effectiveness of Marine Protected Areas. Marine ecosystems are characterized by trophic subsidies: consumers forage between habitats, and ungrazed primary production is exported as drift or detritus. However, the trophic relationships we see today may in a sense be unnatural, because intensive fishing of consumers may have fundamentally altered them.
We aim to evaluate the importance of the exchange of consumers and drift between seagrass and reef habitats in Australia and North America. We aim to find out whether fishing alters these processes by studying marine protected areas in both continents.
This work will come at a crucial time for the implementation of Australia's MPA system.

An innovative approach to maximising catchment water yield in a changing climate. Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change. Past solutions of increasing water supply by building dams are no longer easily implemented because of the significant environmental consequences. To maximise yield, better management of current res ....An innovative approach to maximising catchment water yield in a changing climate. Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change. Past solutions of increasing water supply by building dams are no longer easily implemented because of the significant environmental consequences. To maximise yield, better management of current resources is required, dependent on understanding what factors affect water yield and how they may be better manipulated. This project innovatively integrates ecological and hydrological processes by modelling the expression of water use by vegetation and its management and water availability at fine resolutions.Read moreRead less
Refining Restoration Ecology: Is Range of Historical Variability an appropriate concept to guide ecosystem management and restoration? Ecosystem restoration is an urgent task in many Australian landscapes. Range of Historical Variability (RHV) theory provides an influential but largely untested framework to guide restoration activities. We will test the RHV proposition that biodiversity conservation is enhanced if the structure of altered ecosystems is restored within the pre-settlement range. P ....Refining Restoration Ecology: Is Range of Historical Variability an appropriate concept to guide ecosystem management and restoration? Ecosystem restoration is an urgent task in many Australian landscapes. Range of Historical Variability (RHV) theory provides an influential but largely untested framework to guide restoration activities. We will test the RHV proposition that biodiversity conservation is enhanced if the structure of altered ecosystems is restored within the pre-settlement range. Plants, vertebrates and invertebrates will be compared between ?unrestored? Callitris woodlands dominated by post-settlement regrowth, and ?restored? stands where regrowth has been reduced within the RHV. This will be the first test of RHV theory to encompass a range of taxonomic and functional groups at both local and landscape scales.Read moreRead less

Plant secondary metabolites (PSMs) are considered to protect against herbivory, although the mechanisms are not well understood. This project will determine how marsupial folivores avoid toxicity when browsing on Eucalyptus leaf. Blood levels of terpenes, phenols and their metabolites will be measured in the brushtail possum while it feeds on a diet of varying PSM content. We expect to be able to show relationships between the ingestion and blood levels of PSMs and feeding behaviour. This will give a greater understanding of the effect of plant toxins on browsing behaviour, enabling improved foraging models and more effective habitat management.Read moreRead less
