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
A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise. This project aims to address the current gaps in understanding .... A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise. This project aims to address the current gaps in understanding the critical exchanges of water and greenhouse gases (GHGs) combining field methodologies and hydrological models, under different climatic conditions. The intended outcomes will benefit management of GHG emissions, coastal flooding and vulnerable groundwater dependent habitats.Read moreRead less

Summary
Catastrophic shifts: the value of knowing more about ecosystem feedbacks. Ecosystems respond to gradual change in unexpected ways. Feedback processes between different parts of an environment can perpetuate ecosystem collapse, leading to potentially irreversible biodiversity loss. However, it is unclear if greater knowledge of feedbacks will ultimately change environmental decisions. The project aims to identify when feedbacks matter for environmental decisions, by generating new methods that pr ....Catastrophic shifts: the value of knowing more about ecosystem feedbacks. Ecosystems respond to gradual change in unexpected ways. Feedback processes between different parts of an environment can perpetuate ecosystem collapse, leading to potentially irreversible biodiversity loss. However, it is unclear if greater knowledge of feedbacks will ultimately change environmental decisions. The project aims to identify when feedbacks matter for environmental decisions, by generating new methods that predict the economic benefit of knowing more about feedbacks. Combining ecological modelling and value-of-information theory, the outcomes of these novel methods will provide significant and broad environmental benefits, by enabling managers to make informed decisions and stay one step ahead of potential ecosystem collapse.Read moreRead less

The network will fill essential knowledge gaps about interactions of under- and above-ground environmental processes and their responses to disturbance and change. These interactions determine the sustainability of food, clean water, mineral resources and Australian ecosystems, and cannot be studied with existing environmental infrastructure. The 5 foundational sites will host integrated monitoring equipment to observe stocks and fluxes of carbon, water, energy and mass across the “Critical Zone” – the vertical span from plant canopies to fresh bedrock. Joining a burgeoning international movement, the network will catalyse Critical Zone science in Australia.Read moreRead less

Unravelling how ecosystems function through time and space. This project aims to build a whole-of-ecosystem model to trace the biological capture of energy and cycling of matter as it moves through entire river catchments. It is expected to generate new knowledge about ecological responses to environmental streamflow through the novel integration of all major food-web compartments – from dissolved molecules to predatory fish – in a single framework. The expected outcome of this project is an enh ....Unravelling how ecosystems function through time and space. This project aims to build a whole-of-ecosystem model to trace the biological capture of energy and cycling of matter as it moves through entire river catchments. It is expected to generate new knowledge about ecological responses to environmental streamflow through the novel integration of all major food-web compartments – from dissolved molecules to predatory fish – in a single framework. The expected outcome of this project is an enhanced capacity to predict the ecological consequences of future water management scenarios, facilitating more precise management of river systems. This should provide considerable benefits to the health of Australia’s rivers and the contributions these ecosystems make to society, environment, and agriculture.Read moreRead less
Environmentally-friendly strategies for shoreline protection in lakes. Most current approaches to shoreline protection involve the use of ecologically damaging hard structures. Nature-based alternatives are increasingly adopted, but often without scientific evidence that they are environmentally-friendly. With rising sea-levels, the need for coastal protection will increase, so it is essential that we develop ecologically sustainable approaches to shoreline protection. The aim of this study is ....Environmentally-friendly strategies for shoreline protection in lakes. Most current approaches to shoreline protection involve the use of ecologically damaging hard structures. Nature-based alternatives are increasingly adopted, but often without scientific evidence that they are environmentally-friendly. With rising sea-levels, the need for coastal protection will increase, so it is essential that we develop ecologically sustainable approaches to shoreline protection. The aim of this study is to assess changes to biodiversity and ecosystem functions associated with different protection strategies. The research outcomes will be an understanding of the broad ecological impacts from these approaches and will provide the basis for ecologically sustainable shoreline protection in coastal lakes and lagoons.Read moreRead less
