Transformation of vegetation by big herbivores, from the Pleistocene to now. The project aims to provide a coherent understanding of the effects of extinct and extant large herbivores on ecosystems over space and time. The structure and distribution of vegetation types is determined not only by climate and soils, but also by the impacts of herbivores and fire as consumers of plant biomass. Recent research has shown how fire shapes the large-scale distribution of vegetation types, but we do not h ....Transformation of vegetation by big herbivores, from the Pleistocene to now. The project aims to provide a coherent understanding of the effects of extinct and extant large herbivores on ecosystems over space and time. The structure and distribution of vegetation types is determined not only by climate and soils, but also by the impacts of herbivores and fire as consumers of plant biomass. Recent research has shown how fire shapes the large-scale distribution of vegetation types, but we do not have an equivalent understanding of the effects of large ground-dwelling herbivores. The project plans to test the effects of such animals on vegetation structure in the Pleistocene, when mega-herbivores were common, and today, and thus to compare the impacts of fire and herbivores on the distribution of vegetation types.Read moreRead less
Understanding when biocontrol and enemy release affect plant populations. This project aims to determine when introduced species escape from their natural enemies, and when biocontrol efforts succeed. Enemy release and biocontrol are key to our understanding and management of invasions. However there has never been a broad quantitative assessment of the circumstances under which biocontrol and enemy release affect introduced populations. This project will use a combination of meta-analyses and i ....Understanding when biocontrol and enemy release affect plant populations. This project aims to determine when introduced species escape from their natural enemies, and when biocontrol efforts succeed. Enemy release and biocontrol are key to our understanding and management of invasions. However there has never been a broad quantitative assessment of the circumstances under which biocontrol and enemy release affect introduced populations. This project will use a combination of meta-analyses and international field studies to address this knowledge gap. Expected outcomes include a better understanding of the factors that facilitate biological invasions, and improved success of biocontrol agents.Read moreRead less
Forty million Australians: the future of our biodiversity. Many countries have experienced rapid increases in human numbers and natural-resource use. The project will use measured effects on biodiversity from such countries, combined with models of potential changes in Australia's population and climate, to forecast how our biodiversity may be affected up to 2050, and then to plan how to minimize negative impacts.
Origins of a biodiversity hotspot flora: diversification of the Australian Proteaceae. Why does Australia's only biodiversity hotspot, with nearly 3000 endemic plant species, occur in an area with poor soils and low rainfall? This project will analyse DNA sequences from over 1000 plant species of the Australian Proteaceae, many found only in this hotspot, to help us understand the evolutionary and ecological origins of this iconic flora.
How does your garden grow? Scaling functional traits to whole-plant growth. Understanding how the traits of leaves and stems influence plant growth is important because plant growth drives emergent ecosystem properties such as rates of water use and carbon and nitrogen cycling. The project will build a new understanding of trait-growth relationships, focusing on species from four Australian forest types.

Disaggregating and modelling the impacts of land-use change on biodiversity. This project aims to systematically analyse contemporary and historical data on agriculture, energy use and urbanisation, to identify the consumption and technology pathways that can most effectively mitigate the future extent and impact of land-use change. This synthesis is expected to develop new forecasting and optimisation tools using an innovative hierarchical meta-modelling approach. A key outcome would be to resolve inherent global and national trade-offs between ongoing human development and the competing need to conserve habitats, ecosystems, and species.Read moreRead less

Summary
Why do some declining species persist while others go extinct? Global change is driving thousands of species towards extinction. Legislation requires the protection of biodiversity, but current scientific understanding of species declines limits effective action. By taking a new approach to studying species declines, this integrative research aims to identify why some species persist, while others decline.

Global change is driving thousands of species towards extinction. Legislation requires the protection of biodiversity, but current scientific understanding of species declines limits effective action. By taking a new approach to studying species declines, this integrative research aims to identify why some species persist, while others decline. This project is expected to improve understanding of species vulnerability to extinction, and the conditions which allow species to coexist with threats. Anticipated benefits include advancing ecological theory, improving conservation planning, and increasing the efficiency and effectiveness of policy and management to prevent species extinctions.Read moreRead less
