Summary
Assessing the impact of global environmental change on the nutritional ecology of marsupial and insect folivores of Eucalyptus. Higher atmospheric carbon dioxide concentrations are predicted to alter plant nutrient and toxin content, while higher ambient temperatures may compromise the abilities of animals to metabolise plant toxins. This project will assess how climate change scenarios are likely to impact native marsupials and insects that rely on eucalypt leaves for food.
A changing climate for calcification on the Great Barrier Reef: past, present and future. The Great Barrier Reef (GBR) is a national and international icon, recognised through its inscription as a World Heritage Area and economic and social value to Australians. Maintenance of the GBR as we know it is now compromised by a rapidly changing climate. Ocean acidification, warming water temperatures and increased freshwater will progressively be detrimental to the fundamental reef-building process ....A changing climate for calcification on the Great Barrier Reef: past, present and future. The Great Barrier Reef (GBR) is a national and international icon, recognised through its inscription as a World Heritage Area and economic and social value to Australians. Maintenance of the GBR as we know it is now compromised by a rapidly changing climate. Ocean acidification, warming water temperatures and increased freshwater will progressively be detrimental to the fundamental reef-building process of calcification. Informed policy and management strategies in a rapidly changing physical environment require determination, for short and long time frames, of the regional consequences and impacts of changing reef-building capacity.Read moreRead less
Overcoming multiple constraints to wetland forest restoration. This project aims to determine the efficacy of different approaches for restoring wetland forests at the landscape scale. The death and decline of Victoria’s wetland forests, crucial habitat for the endangered helmeted honeyeater and Leadbeater's possum, most likely result from modified flooding patterns, low native tree and shrub recruitment and increased competition from understorey plants. The project intends to reinstate a more n ....Overcoming multiple constraints to wetland forest restoration. This project aims to determine the efficacy of different approaches for restoring wetland forests at the landscape scale. The death and decline of Victoria’s wetland forests, crucial habitat for the endangered helmeted honeyeater and Leadbeater's possum, most likely result from modified flooding patterns, low native tree and shrub recruitment and increased competition from understorey plants. The project intends to reinstate a more natural flood regime, planting native species and reducing competition from dense understorey vegetation. In this way, the project aims to test and advance ecological theory, guide wetland restoration and inform management plans for saving Victoria’s iconic fauna.Read moreRead less
The recovery of seagrass beds: the role of catchments and options for management responses. Seagrass beds once dominated tidal flats but are disappearing at an increasing rate due to human actions, both in Australia and around the world. This project will develop an understanding of the processes that cause these losses, the factors that prevent seagrass-bed re-establishment, and provide a framework for evaluating alternative management options.
Group dynamics, Allee effects and population regulation in cooperative breeders. Understanding population dynamics is crucial for effective conservation biology. In many cases breeding is limited by high density, but in social species the opposite is true, exposing small groups to high extinction risk. However, analyses of population dynamics in social species is rare, limiting our ability to effectively conserve such species.

Establishing research programs with Pacific neighbours benefits Australia's relations with Pacific Island countries generally. This project applies novel research methods to understanding human adaptations to long-term environmental and climatic fluctuations. It will address the National Research Priority goal of responding to climate variability by advancing our understanding of recent climate change in the Australia/Pacific region. It will show that Australian researchers can play a significant role in understanding the spread of humans across the Pacific, and the environmental adaptations required by populations in resource depleted environments. It will increase collaboration between research institutions focusing on the Australia/Pacific region.Read moreRead less

Summary
Snow, shrub and climate feedbacks: impacts of shrub expansion in the Australian alpine zone. This project aims to understand the mechanisms promoting shrub expansion in alpine areas and the consequences of a shrub-dominated landscape in terms of shrubs as hydrological mediators and as biodiversity and ecosystem modifiers. Some shrub species trap wind-blown snow, thereby facilitating seedling survival through soil insulation and increases to meltwater. However, if adaptive and plastic responses t ....Snow, shrub and climate feedbacks: impacts of shrub expansion in the Australian alpine zone. This project aims to understand the mechanisms promoting shrub expansion in alpine areas and the consequences of a shrub-dominated landscape in terms of shrubs as hydrological mediators and as biodiversity and ecosystem modifiers. Some shrub species trap wind-blown snow, thereby facilitating seedling survival through soil insulation and increases to meltwater. However, if adaptive and plastic responses to climate change allows, shrub expansion will have significant negative impacts on alpine biodiversity and ecosystem function. This project will tease apart the interacting effects of snow, recruitment and adaptation to provide models of shrub increase and determine how shrubs modify alpine ecosystem processes and upper catchment hydrology.Read moreRead less
Spatial scale of influence of riparian and catchment land use on stream ecosystem health. Human activities at the landscape scale comprise one of the greatest threats to the ecological integrity of river ecosystems. Government and community groups across Australia are making significant efforts in riparian protection and rehabilitation in an attempt to improve the health of degraded waterways but are hampered in their goal to maximise the environmental gains for every dollar or unit effort inve ....Spatial scale of influence of riparian and catchment land use on stream ecosystem health. Human activities at the landscape scale comprise one of the greatest threats to the ecological integrity of river ecosystems. Government and community groups across Australia are making significant efforts in riparian protection and rehabilitation in an attempt to improve the health of degraded waterways but are hampered in their goal to maximise the environmental gains for every dollar or unit effort invested. The proposed research on understanding the spatial scale of influence of land use and the aggregative effects on stream ecosystems will provide a robust framework to assess various options and optimise benefits from management actions.

The project aims to identify naturally occurring micro-organisms to increase the effectiveness of Green Guard ®, which is a biopesticide used against the Australian plague locust. The project will use next-generation sequencing and other molecular techniques to potentially identify candidate microbes or combinations of microbes that can be added to Green Guard to enhance locust susceptibility. The project also aims to quantify the interactive impact of temperature and nutrition on immune function, disease resistance and host-plant quality of plague locusts; and to explore the combined effects of temperature, habitat and Green Guard, in combination with candidate microbes or pathogens, on the behaviour and collective movement of locusts. It is anticipated that this will have implications for management and control strategies.Read moreRead less
