Australian waters contain a huge range of biodiversity, but are under threat from human activities. To face this challenge and resolve the problems of depleted fisheries and habitat destruction, innovative approaches are required to integrate marine biology with fisheries economics. The research meets this immediate need by developing bioeconomic models of marine reserves to determine reserve location and size, and analyse interactions between reserves and harvested areas under environmental uncertainty. The models will be developed using the latest developments in economics, biology and numerical methods and will be used to conserve Australia's marine biodiversity and improve fisheries management.Read moreRead less
Sustainable Farms: Tree Regeneration and the Future of Farmland Biodiversity. While many government and community initiatives aim to enhance the sustainability of Australian farming systems, none specifically target the important regional-scale threatening process of tree recruitment failure. Unless this problem is addressed urgently, many farming landscapes may be virtually treeless in the future, with severe negative ramifications for both biodiversity and agricultural productivity. 'Sustainab ....Sustainable Farms: Tree Regeneration and the Future of Farmland Biodiversity. While many government and community initiatives aim to enhance the sustainability of Australian farming systems, none specifically target the important regional-scale threatening process of tree recruitment failure. Unless this problem is addressed urgently, many farming landscapes may be virtually treeless in the future, with severe negative ramifications for both biodiversity and agricultural productivity. 'Sustainable Farms' will have major national and community benefits because it will: (1) identify more sustainable farming practices that are conducive to successful tree recruitment in the future, and (2) raise awareness about a much neglected threat to the sustainability of Australian farming landscapes.Read moreRead less
Plutonium - A new tracer of sediment transport into the Great Barrier Reef Lagoon. This work will quantify one of the most controversial threats to the Great Barrier Reef Marine Park, namely the amount of sediment reaching the reef as a consequence of human activities. It will have economic implications for this major Australian tourist attraction, as well as the commercial fishing and agricultural and horticultural industries in the region. The direct economic value associated with these indust ....Plutonium - A new tracer of sediment transport into the Great Barrier Reef Lagoon. This work will quantify one of the most controversial threats to the Great Barrier Reef Marine Park, namely the amount of sediment reaching the reef as a consequence of human activities. It will have economic implications for this major Australian tourist attraction, as well as the commercial fishing and agricultural and horticultural industries in the region. The direct economic value associated with these industries exceeds $1 billion per annum, and around 1 million people visit the inshore areas every year. Management of the park will benefit through improved understanding of the transport of sediment from the rivers to the lagoon and inner reef areas, and the fraction of the sediment attributable to anthropogenic practices.

Recent fire disasters in southern Australia emphasise that wildfire is one of the major social, economic and ecological issues facing the nation. Biodiversity loss and environmental degradation are also substantial national issues. The outcomes and new understanding obtained from this project will have enormous rural, regional, national and international benefits through developing better informed, and ecologically sustainable, principles and practices for biodiversity conservation, vegetation management, and fire management. It also will guide natural resource managers such as national park staff and state forest managers in best practice methods to manage post-fire ecological recovery on land under their jurisdiction.

THE CORAL RECORD OF ENVIRONMENTAL IMPACTS IN THE GREAT BARRIER REEF:QUANTIFICATION OF ANTHROPOGENIC FLUXES. The objective of this proposal is to quantify the environmental impacts of enhanced terrestrial fluxes and climate change on the coral reefs in the Great Barrier Reef. This will be achieved by using an integrated approach based on coral proxy records of river plumes and sea surface temperatures that are preserved in carbonate skeletons of the long-lived (200-400 year old) Porites coral. ....THE CORAL RECORD OF ENVIRONMENTAL IMPACTS IN THE GREAT BARRIER REEF:QUANTIFICATION OF ANTHROPOGENIC FLUXES.

This will be achieved by using an integrated approach based on coral proxy records of river plumes and sea surface temperatures that are preserved in carbonate skeletons of the long-lived (200-400 year old) Porites coral. This will be integrated with monitoring and process studies of river flood plumes and coral reefs and provide a scientific basis to ensure the long-term sustainability of the GBR.Read moreRead less
Biodiversity conservation, vegetation restoration and landscape design. There has been considerable recent activity through major Government-funded programs to restore native vegetation. Despite extensive expenditure, the biodiversity conservation values of restoration remain very poorly known. This innovative project will address this major knowledge gap.

There has been considerable recent activity through major Government-funded programs to restore native vegetation. Despite extensive expenditure, the biodiversity conservation values of restoration remain very poorly known. This innovative project will address this major knowledge gap. It will generate quality data and new principles to guide restoration that maximizes biodiversity conservation. The principal aim is to estimate tree planting effects on vertebrates and assess whether the effects are consistent across different landscapes, farm units and regions. New insights from the project will aid the design of cost-effective and ecologically-effective restoration programs for future landscapes in rural Australian production environments.Read moreRead less

This study will analyse, at a molecular level, the response of coral larvae to stimuli inducing settlement from the plankton and the process of establishment of a sessile, calcified colony. The knowledge gained will facilitate induction of settlement on demand in the most effective way. We will characterise known candidate genes which may be involved in settlement, and reveal a more complete picture using subtractive hybridisation. Studies of the nervous system and the changes that it undergoes at metamorphosis will promote understanding of the control of metamorphosis, and insights into how more complex nervous systems may have evolved.Read moreRead less

A key outcome will be an informed framework for protecting and enhancing biodiversity in the face of global warming. This research will build on previous archaeological and palaeoecological studies into plant processing practices; provide mediation between different approaches to rainforest management and further an understanding of the antiquity of rainforest occupation in the Wet Tropics World Heritage Zone. Aboriginal communities see the collection of archaeological data as pivotal in gaining control over their cultural sites, which leads to partnerships between universities and communities. Furthermore, close institutional and community relationships have increased the flow of knowledge about past Indigenous rainforest management.Read moreRead less
The evolution and conservation consequences of promiscuity in plants pollinated by vertebrates. Pollen dispersal between plants, predominantly by insects and wind, is characteristically restricted to nearest neighbours. Recent molecular analysis of paternity for a Banksia pollinated by nectar-feeding birds showed atypical pollen dispersal, with high multiple paternity, wide outcrossing and local panmixis. With much of the Australian flora also bird-pollinated, our initial results have potentiall ....The evolution and conservation consequences of promiscuity in plants pollinated by vertebrates. Pollen dispersal between plants, predominantly by insects and wind, is characteristically restricted to nearest neighbours. Recent molecular analysis of paternity for a Banksia pollinated by nectar-feeding birds showed atypical pollen dispersal, with high multiple paternity, wide outcrossing and local panmixis. With much of the Australian flora also bird-pollinated, our initial results have potentially wide and novel significance. This project proposes to test the generality of our observations for other vertebrate-pollinated species, and to test the conservation and evolutionary consequences of reduced pollen dispersal caused by habitat fragmentation and declining pollinators for a pollination paradigm facilitating promiscuity.Read moreRead less
