When fire and water mix: do carbon dioxide-related water savings drive woody plant thickening and fire dynamics in a grassy woodland? Australia's woodland landscapes have experienced widespread shrub expansion in the last century due to changes in fire, grazing and atmospheric carbon dioxide.

A global-scale analysis of functional traits in the face of global change. This project uses a global collaboration to develop a novel method for determining the response of extremely diverse animal taxa to global change. The method focusses on morphological traits and their functions and will improve conservation efforts by predicting the types of ecological processes and species threatened.
Predicting the consequences of drought-induced mortality for tree species in a changing climate. Tree mortality will be a dramatic manifestation of climate change as drought intensifies. A pre-existing record of mortality after recent drought in Eucalyptus woodland defines the moisture sensitivity of tree species and will be related to their functional traits, population dynamics and geography. This analysis will search for generalised characters that define the species that will be most suscept ....Predicting the consequences of drought-induced mortality for tree species in a changing climate. Tree mortality will be a dramatic manifestation of climate change as drought intensifies. A pre-existing record of mortality after recent drought in Eucalyptus woodland defines the moisture sensitivity of tree species and will be related to their functional traits, population dynamics and geography. This analysis will search for generalised characters that define the species that will be most susceptible to drought and will identify how future exaggerated drought will reorganise forest communities. The findings will contribute to understanding the vulnerability and resilience of our natural ecosystems with a changing climate.Read moreRead less
Integrating remote sensing, landscape flux measurements, and phenology to understand the impacts of climate change on Australian landscapes. This project aims to combine satellite data with field tower measurements to more accurately map the water and carbon status of Australian landscapes. This will provide valuable information on land surface changes and improve model predictions of water balance, productivity, and health in response to climate change and land use impacts.

Summary
Assessing Eucalyptus forest responses to rising CO2 and climate change. Rising atmospheric CO2 and the associated changes in rainfall regimes are rapidly reshaping how Australia’s forest ecosystems function and underpin our daily life. Whether Australia’s native Eucalyptus trees can withstand the impacts of climate extremes such as drought and heat under rising CO2 is a crucial question that this project aims to resolve. Using an innovative framework that integrates novel knowledge, data assimil ....Assessing Eucalyptus forest responses to rising CO2 and climate change. Rising atmospheric CO2 and the associated changes in rainfall regimes are rapidly reshaping how Australia’s forest ecosystems function and underpin our daily life. Whether Australia’s native Eucalyptus trees can withstand the impacts of climate extremes such as drought and heat under rising CO2 is a crucial question that this project aims to resolve. Using an innovative framework that integrates novel knowledge, data assimilation and ecosystem modelling, this project will provide critically needed evidence to disentangle the multifaceted impacts of climate change to Eucalyptus trees. This will help reduce the predictive uncertainty in assessing the vulnerability and resilience of Eucalyptus forests in the changing Australian landscape. Read moreRead less

Networking environmental science to achieve integrated management of Australian terrestrial biodiversity in an era of environmental change. Human activities impact Australian ecosystems profoundly and compound natural complexity by superimposing environmental changes.

Human activities impact Australian ecosystems profoundly and compound natural complexity by superimposing environmental changes. Thus, understanding, conserving and enhancing Australian biodiversity demands interdisciplinary research and management strategies. These activities lack overarching strategic coordination, being conducted mainly by groups with focused interests. We will develop a Network uniting the skills, resources and energies of excellent and productive researchers and managers of natural resources across the relevant disciplines and organizations, and so work synergistically towards the National Research Priority of an Environmentally Sustainable Australia.Read moreRead less
Ants, plants, diversity and function: trophic interactions and ecosystem function in a large-scale restoration experiment. Food and clean water are but two of the benefits we reap from functioning ecosystems, but we know little about how individual species contribute to making ecosystems work. This project capitalises on the diversity of Australia's ant fauna by using ants as a model taxon to explore the link between biodiversity and ecosystem functioning.
Models for biodiversity futures for massively altered agricultural landscapes. Problems with soil and water and declines in native biodiversity have been linked to clearance of native vegetation. We consider future landscapes with substantially more native vegetation than at present to deal with these natural resource problems. Plantings will be slow to mature so optimal planning for landscape revegetation must consider how long it will take for the new vegetation to provide suitable habitat, bo ....Models for biodiversity futures for massively altered agricultural landscapes. Problems with soil and water and declines in native biodiversity have been linked to clearance of native vegetation. We consider future landscapes with substantially more native vegetation than at present to deal with these natural resource problems. Plantings will be slow to mature so optimal planning for landscape revegetation must consider how long it will take for the new vegetation to provide suitable habitat, both at patch and landscape scales. We will develop an optimization framework incorporating models of vegetation maturation and biotic responses to aid designs for placement and scheduling of replantings to give the best outcomes for biodiversity management given constraints on amounts of retired area and costs of implementation.Read moreRead less
The role of behavioural interactions in shaping invasion dynamics: A global synthesis using the common myna as a model system. Invasive species have detrimental effects on human health, the economy and native biodiversity. This study will address a major gap in our scientific understanding of invasions by undertaking the first large-scale examination of the role of interactions between species in determining the dynamics and outcomes of biological invasions.

Invasive species have detrimental effects on human health, the economy and native biodiversity. This study will address a major gap in our scientific understanding of invasions by undertaking the first large-scale examination of the role of interactions between species in determining the dynamics and outcomes of biological invasions. The project will integrate data, across four continents, on dispersal, demography, breeding and behavioural interactions into one framework to create a cutting-edge model of invasion dynamics, using the highly invasive common myna as a model system. This novel approach will significantly advance theoretical developments in invasion biology and will inform pest management and threat mitigation efforts globally.Read moreRead less
