Silicon: a novel solution to reduce water use and pest damage in wheat. 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 a ....Silicon: a novel solution to reduce water use and pest damage in wheat. 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

Summary
Responses of fish to climate change. Climate variation will continue to impact biodiversity on our globe. Exciting new evidence has suggested that terrestrial ectotherms can minimise their vulnerability to changing temperatures by altering their thermoregulatory behaviour. Fish, unlike terrestrial ectotherms do not possess the same ability to thermoregulate and it is unclear how behavioural changes may reduce a population's vulnerability to climate change. This project aims to combine bio-loggin ....Responses of fish to climate change. Climate variation will continue to impact biodiversity on our globe. Exciting new evidence has suggested that terrestrial ectotherms can minimise their vulnerability to changing temperatures by altering their thermoregulatory behaviour. Fish, unlike terrestrial ectotherms do not possess the same ability to thermoregulate and it is unclear how behavioural changes may reduce a population's vulnerability to climate change. This project aims to combine bio-logging technology, energy budget theory and climate models to predict the potential role that changing behaviours may have in reducing the vulnerability of fish populations to climate change.Read moreRead less
Connectivity and movements of large pelagic species of ecotourism value. The project aims to answer key questions about the biology, ecology and sustainability of the world’s manta ray species to provide the information and tools for management and conservation of these charismatic and valuable species. In particular, the project aims to determine the likely impact of climate variability and fisheries that operate to Australia’s north on manta-based ecotourism in the Indo-Pacific region, as clim ....Connectivity and movements of large pelagic species of ecotourism value. The project aims to answer key questions about the biology, ecology and sustainability of the world’s manta ray species to provide the information and tools for management and conservation of these charismatic and valuable species. In particular, the project aims to determine the likely impact of climate variability and fisheries that operate to Australia’s north on manta-based ecotourism in the Indo-Pacific region, as climate change and active low-value fisheries may both jeopardise a high-value ecotourism industry. The project seeks to explore geographic distributions, local and large-scale movements, population sizes, structure, and inter-connectivity in the region to assess the effect of climate and fisheries on manta ray populations.Read moreRead less
Ecological responses of native fishes to dynamic water flows in northwest arid Australia. This project will investigate the biological adaptations and ecology of native fishes of northwest Australia in order to assess their resilience to altered water flows due to mining activities and changing climate. The project findings will contribute to sustainable management of water and biodiversity in arid environments.
Origin and evolution of plant functional traits in relation to fire. This project addresses the fundamental question as to what extent the Australian flora is adapted to fire by tracing the evolutionary history of the iconic family Proteaceae over the last 100 million years. The answer to this question has significant implications for informing Australia’s fire management and nature conservation policies.
A novel top-down approach to ecosystem management using multivariate foraging strategies of an iconic marine top-predator. Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species. The project aims to develop a new approach to measure prey abundance and availability in the marine ecosystem for the management of resources of top-predators. This will be of specific benefit i ....A novel top-down approach to ecosystem management using multivariate foraging strategies of an iconic marine top-predator. Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species. The project aims to develop a new approach to measure prey abundance and availability in the marine ecosystem for the management of resources of top-predators. This will be of specific benefit in areas where a strong need exists for conservation of prey species with economic importance too low to justify expensive at-sea research.Read moreRead less
Identifying potential trade-offs of adapting to climate change. Climate change and marine heatwaves introduce strong, directional selection for heat tolerance which, in turn, alters the genetic composition and diversity of marine species. While this may facilitate adaptation to warmer conditions, reduced genetic diversity may limit resilience or cause maladaptation to additional stressors. This project will focus on habitat-forming kelps and will aim to both assess the negative consequences of r ....Identifying potential trade-offs of adapting to climate change. Climate change and marine heatwaves introduce strong, directional selection for heat tolerance which, in turn, alters the genetic composition and diversity of marine species. While this may facilitate adaptation to warmer conditions, reduced genetic diversity may limit resilience or cause maladaptation to additional stressors. This project will focus on habitat-forming kelps and will aim to both assess the negative consequences of rapid selection and to disentangle the mechanisms of climate adaptation. Through a powerful combination of controlled experiments on known genotypes and cutting-edge transcriptomic approaches, this project will transform our understanding of the adaptability of foundation species in a rapidly changing ocean.

What drives novel community formation? Mechanisms of resilience against invasion and native species persistence under land use change. Environmental change is driving the creation of novel communities, stable mixes of native and exotic species. These communities are inevitable outcomes of human-induced environmental changes, yet why and how they form is still poorly understood. As these communities maintain high levels of native biodiversity, they are of great conservation value. Using Western A ....What drives novel community formation? Mechanisms of resilience against invasion and native species persistence under land use change. Environmental change is driving the creation of novel communities, stable mixes of native and exotic species. These communities are inevitable outcomes of human-induced environmental changes, yet why and how they form is still poorly understood. As these communities maintain high levels of native biodiversity, they are of great conservation value. Using Western Australia wildflower communities, This project aims to provide the first experimental tests of which environmental and biotic factors drive novel community formation, native species persistence and resilience to invasion. This will be important for developing realistic conservation plans in many ecosystems globally, and more specifically in Western Australia's biodiversity hotspot.Read moreRead less
Turf Wars: fighting the new battle facing blue forests. 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.

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
Global threats to kelp forests from heatwaves, herbivores and diseases. This project aims to understand the mechanisms behind climate-mediated declines in kelp. Ocean warming causes the collapse of valuable temperate kelp forests globally and on both sides of Australia, but it is unknown if this is because of direct physiological effects from temperature or the indirect effects of changes in species interactions. This project will compare the direct effects of marine heatwaves to the indirect ef ....Global threats to kelp forests from heatwaves, herbivores and diseases. This project aims to understand the mechanisms behind climate-mediated declines in kelp. Ocean warming causes the collapse of valuable temperate kelp forests globally and on both sides of Australia, but it is unknown if this is because of direct physiological effects from temperature or the indirect effects of changes in species interactions. This project will compare the direct effects of marine heatwaves to the indirect effects of range-shifting tropical herbivores and pathogens for the kelp forests of the Great Southern Reef, one of Australia’s largest coastal ecosystems. This project will generate knowledge underpinning adaptation strategies for these critical ecosystems, and could enhance the capacity to respond to degradation of these natural assets.Read moreRead less
