Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will b ....Investigating movement, distribution, abundance and diet to support management objectives for threatened riverine predators in Northern Australia. The rivers and estuaries of northern Australia are highly productive environments, containing an exceptional diversity and abundance of large predatory aquatic species. This project aims to monitor the movements, habitat preferences and diet in eight large predatory species in a northern Queensland river over the next three years. Movement data will be combined with isotopic analysis to reveal how environmental and biological factors drive animal movements and impact habitat connectivity. In a world of vanishing top predators, it is imperative to understand system dynamics before we can evaluate the impact of species removal on ecosystem function.Read moreRead less
A novel approach for assessing environmental flows using satellite data. This project will determine how ecosystems respond to environmental flow by linking flooding history with vegetation responses, using remote sensing, climate data layers, spatial statistics, models of environmental flows and ecological theory. Beneficiaries will include water and land managers in Australia.
Functional links between estuaries and their catchments: How does land use change affect estuarine ecological and bio-geochemical function? Estuaries are iconic recreational areas of high ecological and socio-economic value. Estuarine health is strongly linked to the catchments that feed them, yet we have no detailed understanding of these links. This project will use a number of state of the art approaches to better understand how land use affects estuarine health.
Optimisation of catchment management: stable isotope studies of water storage and yield. Focusing on the Cotter catchment, this project will establish how the water content of soils and tree stems regulates the amount of water used by trees in sub-catchments, and thus how much reaches streams and dams. Small areas supply most of the water yield and this project will help identify where managers should focus efforts to increase yield.

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
Reintroduction of ecosystem engineers as a woodland restoration tool. Can we help restore woodlands by reintroducing extinct native mammals? Through a strategic partnership combining innovative research and conservation action, this project will investigate how returning extinct 'ecosystem engineers' could be used as a tool for restoring healthy temperate woodland ecosystems.
Understanding grassy woodlands as whole ecosystems. Restoring Australia's once vast grassy woodlands needs a sound understanding of the whole ecosystem and robust scientific evidence to inform conservation action. This project will generate such evidence by establishing a National Outdoor Laboratory to inform the sustainable management of our nation's precious remaining woodlands.
