Adaptive management of arid and semi-arid ecosystems. Australia’s arid zones contain some of the world’s most threatened ecosystems. Management must begin immediately, but our understanding of these fragile species and ecosystems is currently very limited. This project will develop and apply new research in Adaptive Management (“learning by doing”) to ensure the persistence of these rare places.
New tracer methods for revealing the hidden connections between ecosystems. 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 positiv ....New tracer methods for revealing the hidden connections between ecosystems. 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
Apex predator control of nutrient dynamics. This project aims to understand the mechanisms through which predators can control ecosystem nutrient dynamics. Ecology has been dominated for decades by the top-down/bottom-up paradigm. The project will use experiments and remote sensing observations to examine the spatial structure of feedback loops between a top predator and nutrient cycles. The expected outcome is a mechanistic and scalable understanding of the spatial distribution of nutrients and ....Apex predator control of nutrient dynamics. This project aims to understand the mechanisms through which predators can control ecosystem nutrient dynamics. Ecology has been dominated for decades by the top-down/bottom-up paradigm. The project will use experiments and remote sensing observations to examine the spatial structure of feedback loops between a top predator and nutrient cycles. The expected outcome is a mechanistic and scalable understanding of the spatial distribution of nutrients and push ecosystems towards alternate states. The project will provide innovative approaches to scale-up ecological data that can be used to inform the decisions of policy makers and land managers.Read moreRead less
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.
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.
The spatial energetics of pollination failure in habitat restoration. This project addresses the reasons for pollination failure of threatened plant species during habitat restoration. Specifically, the project will determine the role of energetic constraints on pollinator movement in the hostile landscape matrix surrounding urban woodland remnants, and model future scenarios for restoring natural functioning woodland ecosystems.
