Explaining biodiversity. Why are there many species in some places and not in others? The aim of this project is to understand this in order to protect species, understand invasion and restore ecological systems. Using published food webs, this project will determine what factors underlie biodiversity, then use experiments to understand effects of habitat loss and climate change on food web structure.
How arid zone wetlands persist: linking ecological dynamics with hydrological regimes . This project will investigate how aquatic food webs assemble and persist in mound springs, relict streams and river pools in the Australian arid zone. Knowing how aquatic systems respond to wet and dry phases is the first step towards ‘climate proofing ’ these systems against future extreme events.

Summary
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
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
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
Extinction of turtles in the River Murray: Consequences and Solutions. Turtles are a major ecological component of the Murray-Darling, Australia’s major river system. They are declining alarmingly with potential dire consequences for water quality, biodiversity, and river health. This project unites a world-class research team with diverse industry partners, indigenous groups, and non-government organisations from three states to address a problem of national significance. This project aims to i ....Extinction of turtles in the River Murray: Consequences and Solutions. Turtles are a major ecological component of the Murray-Darling, Australia’s major river system. They are declining alarmingly with potential dire consequences for water quality, biodiversity, and river health. This project unites a world-class research team with diverse industry partners, indigenous groups, and non-government organisations from three states to address a problem of national significance. This project aims to identify and quantify causes of declines in turtles along the whole system, with the aim of developing practical management options to overcome it. This will be the first river-wide study of turtles, achieved by combining cutting-edge genetic and ecological techniques with a citizen science program.Read moreRead less
Aquatic biodiversity: consequences of massive modification of agricultural landscapes. Agricultural landscapes have undergone great change. Significant shifts in land-use may sustain agricultural productivity, but nationally we risk the loss of our natural wealth - native plants and animals. This project develops a new vision for assessing conservation values of rural landscapes that will help land managers to plan for present and future land-use of both terrestrial and aquatic organisms. It wil ....Aquatic biodiversity: consequences of massive modification of agricultural landscapes. Agricultural landscapes have undergone great change. Significant shifts in land-use may sustain agricultural productivity, but nationally we risk the loss of our natural wealth - native plants and animals. This project develops a new vision for assessing conservation values of rural landscapes that will help land managers to plan for present and future land-use of both terrestrial and aquatic organisms. It will help managers to understand the biodiversity value of different landscapes, the types of species that may persist or be at risk of loss, and the landscape components that influence these outcomes. This knowledge will enhance our national capacity to jointly integrate nature conservation and agricultural productivityRead moreRead less
The importance of dispersal in maintaining biodiversity of aquatic plants in landscapes. Aquatic plants improve water quality and provide habitat for aquatic animals, which underpin industries such as tourism and commercial fisheries critical to economies in regional areas and across Australia. Preserving plant biodiversity of aquatic ecosystems is vital to preserve these benefits. Dispersal plays a critical role in maintaining plant biodiversity and requires understanding at landscape scales. T ....The importance of dispersal in maintaining biodiversity of aquatic plants in landscapes. Aquatic plants improve water quality and provide habitat for aquatic animals, which underpin industries such as tourism and commercial fisheries critical to economies in regional areas and across Australia. Preserving plant biodiversity of aquatic ecosystems is vital to preserve these benefits. Dispersal plays a critical role in maintaining plant biodiversity and requires understanding at landscape scales. This project will identify appropriate approaches for the conservation of plant biodiversity in aquatic ecosystems through an improved understanding of the contribution of wind, water and waterbirds in the dispersal of aquatic plants. This project will also identify water flow regimes that promote a diverse and sustainable aquatic flora.Read moreRead less
Systematic planning beyond conservation: a multi-objective, multi action framework for sustainable biodiversity. When planning for conservation in rivers, protecting plants and animals can not simply be achieved by protecting parts of a river. This project will develop a strategy to sustain freshwater biodiversity that will optimally allocate conservation and restoration resources and minimises negative socioeconomic impacts on stakeholders.

The project will develop and test a new global standard for the assessment and reporting on ecological condition of internationally important wetlands, listed under the Ramsar Convention. It has four aims: establishment of a strategic adaptive management and governance framework, a meta-analysis of the 2,303 internationally listed wetlands, development of a protocol for assessment and prediction and delivering a digital reporting platform for effective management. The project is significant because it tackles the decline of freshwater ecosystems, by targeting the most prominent wetlands. It also assists state and national governments to meet their obligations under the Ramsar Convention and most importantly guides more effective management.Read moreRead less
