Escalating the arms race: Understanding when and how trees get really tall. Australia's giant Eucalypt trees are an amazing phenomenon and resource; underpinning unique ecosystems, rich in timber, stored carbon, and animal habitat. While tree height generally arises via an evolutionary arms race for light, the race has escalated dramatically in some locations and species. Using a computational framework that simulates adaptation driven by size-structured competition, this project will quantify h ....Escalating the arms race: Understanding when and how trees get really tall. Australia's giant Eucalypt trees are an amazing phenomenon and resource; underpinning unique ecosystems, rich in timber, stored carbon, and animal habitat. While tree height generally arises via an evolutionary arms race for light, the race has escalated dramatically in some locations and species. Using a computational framework that simulates adaptation driven by size-structured competition, this project will quantify how distinct factors-including climate, recruitment, and disturbance-enhance the race for light and can thereby explain the origins of Australia's giant Eucalypt. With calibrated models of species evolution, coupled with targeted fieldwork and big data, this project clarifies key forces shaping present and future vegetation.Read moreRead less

The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si alleviates stress in wheat, from gene to farm scale, providing cost-benefit analysis and a best–practice toolbox for implementation by farmers. Outcomes are anticipated to provide a cheaper and more environmentally sustainable solution to issues of water scarcity and yield losses to pests in Australia’s leading crop.Read moreRead less

Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ecoinformatics and evolutionary theory. Across this span, working groups will target nine identified opportunities for breakthrough research. Each research target needs input from two or more disciplines. Together, the nine targets link across disciplines, as a network that spans from genomic to planetary scales.Read moreRead less

This project aims to improve the success of hybrid living shorelines that combine the restoration of mangroves and oysters with engineered structures to enhance restoration outcomes and coastal hazard resilience. It expects to generate new knowledge on the effectiveness of innovative coastal-manager-led solutions that have not yet been robustly evaluated. Expected outcomes of this project include delivery of the technical guidelines needed to practically design and implement nature-based coastal protection at scale. This should provide significant socio-economic and environmental benefits through improving Australia’s capacity to adapt to increased erosion and flood risk caused by climate change and coastal urbanisation.Read moreRead less
Understanding snow gum dieback for effective and integrated management. The project leverages recent research and infrastructure investments and our determined and collaborative team as it aims to: 1) assess the future geography of snow gum dieback in the high country and identify priority locations for pro-active management, 2) quantify the impact of snow gums on high country water and carbon budgets and thus the socio- economic and biodiversity values, and 3) determine options for mitigation. ....Understanding snow gum dieback for effective and integrated management.

Resolving the warming East Australian Current's impact on a marine food web. This project aims to understand the effects of climate change on marine food webs, from plankton production to predation by iconic marine fauna, by integrating data on oceanographic conditions and fish distribution with the foraging patterns and breeding success of seabirds. Warming waters due to strengthening western boundary currents have unknown consequences for coastal marine food webs. Innovative prey capture signatures from accelerometers, and advanced movement models from satellite locations will show how predators locate and prey upon fish schools. Anticipated outcomes are insight into how changing resource availability in the oceans affects ecosystem resilience; improved viability for coastal industries; and ecosystem-based conservation management strategies.Read moreRead less
Can consistent individual differences in metabolic rate explain animal personality? Implications for fish and aquaculture in a warming climate. This project will determine if consistent individual differences in metabolic rate affect behaviour, growth, and reproduction in fish. If so, then we need to prepare for the fact that a warming climate will lead to reductions in fish growth and reproduction, because rising temperature directly increases metabolism and therefore maintenance costs.

This project aims to use ecological models and field experiments to uncover drivers and critical thresholds for turf expansion. Habitat loss is a leading threat to goods and services from the oceans. Globally, kelp forests are collapsing and being replaced by persistent unwanted algal ‘turfs’. Understanding of this habitat shift is rudimentary, and solutions to mitigate the impacts virtually non-existent. Through stress experiments and genomic analyses, this project aims to discover resilient kelps that promote forest persistence under stress. By expanding our understanding of critical habitat transitions, and exploring new solutions, this project aims to enhance our capacity to respond to the ongoing degradation of Australia’s Great Southern Reef.Read moreRead less
