As humans modify the biosphere, many complex landscape-level problems are emerging. New methods are required to work on these large-scale problems. The aim of this project is to develop novel methods involving trace elements and isotopes, opening up new ways to explore the large-scale connections between terrestrial ecosystems and downstream estuaries. It is planned to use these new methods to test for unexpected positive benefits of floods for estuarine fisheries. The project is significant and innovative because it develops two fundamentally new types of tracer work, one at the sediment-animal level and one at the within-molecule level. The expected outcomes include a new toolkit for tracing the hidden connections between terrestrial and aquatic ecosystems.Read moreRead less
The importance of edge effects in determining the value of seagrass landscapes as fish nurseries. Seagrasses are a conspicuous element of Australian marine environments, and are crucial in the conservation and maintenance of biodiversity. Degradation of seagrass ecosystems from climatic extremes, increased sediment and nutrients in the water, and other pollutants results in loss and fragmentation of meadows. These changes to seagrass are linked with increased coastal erosion, severe loss of bio ....The importance of edge effects in determining the value of seagrass landscapes as fish nurseries. Seagrasses are a conspicuous element of Australian marine environments, and are crucial in the conservation and maintenance of biodiversity. Degradation of seagrass ecosystems from climatic extremes, increased sediment and nutrients in the water, and other pollutants results in loss and fragmentation of meadows. These changes to seagrass are linked with increased coastal erosion, severe loss of biodiversity, and collapse of fisheries. Increased understanding of how biological processes such as predation and food availability influence animal associations with seagrasses, and how these effects change with landscape structure, will have important applications in the sustainable management of Australia's threatened coastal habitats.Read moreRead less
Achieving biodiversity conservation and ecosystem service delivery: the role of landscape structure. Achieving gains for human well-being and, at the same time, conserving biodiversity is the ultimate challenge for conservation policy. This project will develop new understandings and new methods to address this issue, with important impacts on the effectiveness of strategies to conserve biodiversity.
Can we see the wood for the trees? Effective restoration strategies in rapidly changing subtropical river systems. Addressing the issue of degraded waterways nationally will cost billions of dollars; in southeast Queensland alone it is estimated that it will cost $500 million. Fundamental research is needed to ensure such efforts achieve the desired outcomes. Previous research has shown riverbank erosion is a key stressor for water quality. This project aims to link fluvial disturbance with the ....Can we see the wood for the trees? Effective restoration strategies in rapidly changing subtropical river systems. Addressing the issue of degraded waterways nationally will cost billions of dollars; in southeast Queensland alone it is estimated that it will cost $500 million. Fundamental research is needed to ensure such efforts achieve the desired outcomes. Previous research has shown riverbank erosion is a key stressor for water quality. This project aims to link fluvial disturbance with the capacity for effective riparian restoration in subtropical river systems at a local, reach and whole of catchment scale. The outcome aims to develop decision-support tools and methods for industry partners to invest in catchment-scale restoration activities in order to manage the risks to drinking water quality and aquatic ecosystem health from riverbank erosion.Read moreRead less
Towards a Landscape Conservation Culture - broadening the spatio-temporal scope of ecological studies to anticipate change in Australian forested ecosystems. This project in south-western Australia develops an integrated framework to interpret knowledge about landscape processes and future trajectories of species and assemblages at different spatio-temporal scales.

This project in south-western Australia develops an integrated framework to interpret knowledge about landscape processes and future trajectories of species and assemblages at different spatio-temporal scales. A synthesis of data obtained through repeated biological surveys and remote sensing, with spatial data handled through GIS is used in an explanatory modeling approach to make predictions under different disturbance regimes. Models built from combined spatial layers exhibiting continuous variation in environmental variables will provide area-class maps at different scales, allowing the portrayal of uncertainty associated with vegetation units - a considerable innovation over maps depicting homogenous discrete zones.Read moreRead less

Conserving and recovering the koala populations on NSW Far North Coast. This project aims to develop a novel, integrated socio-ecological approach for connecting landscapes and communities for the recovery of threatened koala populations on the New South Wales far north coast. This should increase understanding of how local landholders and land managers respond to koala recovery programs and why they respond positively and become engaged for the long-term. The intended outcome is a spatial prioritisation framework for species recovery that integrates social and ecological values, and increased global knowledge of how to recover declining wildlife populations.Read moreRead less

Critical regions and network connectivity of coral reef ecosystems. This project aims to measure the degree of connectivity between isolated reefs in Australia's Coral Sea and the Great Barrier Reef and identify the biological and environmental mechanisms that enhance management strategies or mitigate against disturbances. The movement of individuals in fragmented landscapes plays a central role in the ecology and evolution of species. The project seeks to measure connectivity at multiple scales ....Critical regions and network connectivity of coral reef ecosystems. This project aims to measure the degree of connectivity between isolated reefs in Australia's Coral Sea and the Great Barrier Reef and identify the biological and environmental mechanisms that enhance management strategies or mitigate against disturbances. The movement of individuals in fragmented landscapes plays a central role in the ecology and evolution of species. The project seeks to measure connectivity at multiple scales and identify critical regions for the design of networks of marine protected areas. This is anticipated to improve our understanding of connectivity in marine seascapes and benefit management of important fishery species and current efforts in coral reef conservation.Read moreRead less

The project plans to develop a new understanding of the capacity of forests to increase moisture recycling, which enhances cloud and precipitation processes and exerts a cooling influence on the land surface. Deforestation and climate change are major global challenges. The role of forests in the carbon cycle is well recognised. Less attention is given to their role in the energy and water cycles, and their capacity to regulate regional climate. The project plans to apply an innovative land use-climate scenario modelling to quantify the impacts of deforestation and afforestation on the climate of northern Australia and south-east Asia under global warming. It also plans to evaluate the capacity of restoring forests to offset regional climate change, to inform regional land use planning and climate mitigation and adaptation.Read moreRead less
