Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for p ....Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for predicting climate change resilience that can be applied to many species. The intended benefits include increasing our understanding of the potential for native bees to act as future pollinators in Australia’s natural and agro-ecosystems, and guide policy and management decisions to better protect and conserve our bee fauna.Read moreRead less
How does climate affect regeneration and distribution of Australian plants? This project aims to quantify the degree to which Australian plant species have responded to changes in climate over the last few decades, and to build understanding of the mechanisms that underpin responses to climate change. It seeks to fill critical knowledge gaps about the way heatwaves, freezing temperatures and temperature variability affect plants. The project aims to introduce a novel approach that will allow ass ....How does climate affect regeneration and distribution of Australian plants? This project aims to quantify the degree to which Australian plant species have responded to changes in climate over the last few decades, and to build understanding of the mechanisms that underpin responses to climate change. It seeks to fill critical knowledge gaps about the way heatwaves, freezing temperatures and temperature variability affect plants. The project aims to introduce a novel approach that will allow assessment of physiological and morphological change in response to recent climate change in the absence of historic data. Improved accuracy in identifying species that will have trouble responding to climate change would allow managers to more effectively target their resources to maximise biodiversity and ecosystem function.Read moreRead less
Finding damage thresholds in pyrethrum to optimise crop profitability. This project aims to use a new vascular approach to develop a quantitative stress tolerance framework for the crop species pyrethrum, defining the risks to plant production of water, heat and frost stress. Using novel optical and x-ray technology, this project seeks to pinpoint damaging stress thresholds and combine this knowledge with crop monitoring technology in a way that will allow crop managers to avoid damaging stress ....Finding damage thresholds in pyrethrum to optimise crop profitability. This project aims to use a new vascular approach to develop a quantitative stress tolerance framework for the crop species pyrethrum, defining the risks to plant production of water, heat and frost stress. Using novel optical and x-ray technology, this project seeks to pinpoint damaging stress thresholds and combine this knowledge with crop monitoring technology in a way that will allow crop managers to avoid damaging stress events. The intended outcome is to enable the pyrethrum industry, and ultimately a diversity of crop managers, to better utilise new advances in monitoring technology to maximise the benefits of irrigation such that yields are high relative to water use and damage by stress is avoided. Immediate beneficiaries will be the pyrethrum industry, but the research will provide a model, applicable to the multitude of irrigated crops in Australia. 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.
How do Microbes Grow in High Salt at Very Cold Temperatures. The proposed research aims to define mechanisms of survival and speciation that underpin the capacity of a novel group of Antarctic microorganisms to evolve dominance in their very cold (-20 degrees Celsius) and very salty environment. Most (~85 per cent) of the Earth's biosphere is cold (<5 degrees Celsius), and yet contains a rich diversity of microorganisms of which we know little. The uniqueness and sensitivity of Antarctica partic ....How do Microbes Grow in High Salt at Very Cold Temperatures. The proposed research aims to define mechanisms of survival and speciation that underpin the capacity of a novel group of Antarctic microorganisms to evolve dominance in their very cold (-20 degrees Celsius) and very salty environment. Most (~85 per cent) of the Earth's biosphere is cold (<5 degrees Celsius), and yet contains a rich diversity of microorganisms of which we know little. The uniqueness and sensitivity of Antarctica particularly demands that we rapidly improve our understanding of its biology. The discoveries made could provide fundamental insight about speciation - processes controlling which life forms that colonise the planet.Read moreRead less

This project aims to identify factors that counter the negative impacts of climate change on coral reefs. This project expects to address key research gaps to ensure the persistence of these ecosystems. Expected outcomes of this project include identification of coral reefs that are buffered by adjacent systems, such as mangroves and seagrass, and characterisation of conditions (e.g. increased food availability) that allow coral reefs and associated organisms to persist under stress. Outcomes of this project should provide significant benefits such as adding to the interventions toolbox in alleviating the impacts of global change on coral reefs and identifying conservation strategies to help prevent the loss of these valuable ecosystems.Read moreRead less

As the oceans simultaneously warm and acidify, prospects for marine biota are of concern. This project aims to determine the potential for phenotypic adjustment and evolutionary adaptation. To discern the roles of phenotype and genotype in marine invertebrate stress tolerance this project endeavours to use selection experiments, long-term rearing and quantitative genetics . A focus on vulnerable calcification systems could determine genetic mechanisms underlying impaired growth. Investigation of species from the east Australia latitudinal thermal gradient, a global change hot spot could generate insights into biological responses and adaptive potential in a changing ocean and on time scales relevant to resource managers to understand the challenges faced by marine biota.Read moreRead less

Summary
Interplay between plasticity and senescence. This project aims at bridging two fundamental human stressors together in a quantitative genetic framework. The environment changes globally on a huge scale coupled with effect on the age-structures and genetic composition of countless populations by over-harvesting and exploitation. This project will provide significant benefits, such as potential strategies of dealing with future human-induced changes more effectively.
Oyster adaptation to climate change via transgenerational plasticity. We are in an age of rapid climate change, where the need to understand the adaptive potential of marine organisms in warmer, more acidified oceans is increasingly urgent. This is especially true in Australia where changes are significant. This project uses a cutting-edge, integrated interdisciplinary approach to measure the capacity of oysters to adapt and persist to climate change via transgenerational plasticity, describe th ....Oyster adaptation to climate change via transgenerational plasticity. We are in an age of rapid climate change, where the need to understand the adaptive potential of marine organisms in warmer, more acidified oceans is increasingly urgent. This is especially true in Australia where changes are significant. This project uses a cutting-edge, integrated interdisciplinary approach to measure the capacity of oysters to adapt and persist to climate change via transgenerational plasticity, describe the epigenetic mechanisms which underlie it and develop an immediate breeding method to protect vulnerable oysters and other marine organisms against climate change. The research outcomes will transform Indigenous-led oyster reef restoration projects and future-proof an iconic food source and national industry.Read moreRead less
Australian and global plant diversity from first principles. This project aims to explain the composition of vegetation in Australia and worldwide using ecological and evolutionary first principles. Researchers have studied how climate shapes vegetation for centuries, but still lack a basic quantitative theory predicting what types of plants should be found where and why. Combining first principles models, statistics and large Australian data synthesis, this project will determine whether vegeta ....Australian and global plant diversity from first principles. This project aims to explain the composition of vegetation in Australia and worldwide using ecological and evolutionary first principles. Researchers have studied how climate shapes vegetation for centuries, but still lack a basic quantitative theory predicting what types of plants should be found where and why. Combining first principles models, statistics and large Australian data synthesis, this project will determine whether vegetation structure and diversity is predictable and thus improve predictive models. Predicting the long term effects of evolutionary adaptation and humans on ecosystems could enable the management of terrestrial carbon and underpin effective ecosystem management and restoration.Read moreRead less
