Comparative Paleogenomics of the Arctic Tundra Ecosystem: the genetic response of plants and animals to climate change. This project will use DNA from deep-frozen seeds and bones 100,000 years old to record how species respond to climate change - by adapting and surviving or by shifting ranges and moving. Very large numbers of genes will be examined to identify changes across the genomes of four plant and two animal species, and contrast the responses to major climatic shifts.
Adaptive capacity of marine invertebrates in a climate change ocean. 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 dete ....Adaptive capacity of marine invertebrates in a climate change ocean. 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
How climate-resilient are our temperate fisheries species? This project assesses the resilience of our temperate fisheries species to climate change. Using natural warming hotspots and volcanic CO2 vents we study populations of fisheries species that are already pre-adapted to future climate, and therefore could act as key populations for replenishment of future fisheries stocks. An innovative and interdisciplinary approach combines the ecology, genetics, behaviour, and physiology of fisheries s ....How climate-resilient are our temperate fisheries species? This project assesses the resilience of our temperate fisheries species to climate change. Using natural warming hotspots and volcanic CO2 vents we study populations of fisheries species that are already pre-adapted to future climate, and therefore could act as key populations for replenishment of future fisheries stocks. An innovative and interdisciplinary approach combines the ecology, genetics, behaviour, and physiology of fisheries species to evaluate their climate resilience. An advanced food web model will be developed to forecast changes to fisheries production in a future world. This provides a much-improved forecast of climate adaptation and managing future biodiversity and fisheries species through resilient genes and populations.Read moreRead less
Using phylogenomics to record the impacts of climate change, extinction and population fragmentation. This project will use ancient DNA from permafrost-preserved Steppe bison bones and bovid exome capture systems to build a detailed record of the genomic impacts of rapid climate and environmental change at the end of the Pleistocene (30 to 11 kyr). The project will analyse how ancestral genetic diversity is distributed amongst surviving bison populations, and the role of nuclear loci under selec ....Using phylogenomics to record the impacts of climate change, extinction and population fragmentation. This project will use ancient DNA from permafrost-preserved Steppe bison bones and bovid exome capture systems to build a detailed record of the genomic impacts of rapid climate and environmental change at the end of the Pleistocene (30 to 11 kyr). The project will analyse how ancestral genetic diversity is distributed amongst surviving bison populations, and the role of nuclear loci under selection and drift. It will create a novel temporal dataset of genomic adaptation and evolution, and will generate critical data for studies of evolutionary processes such as extinctions, speciation and conservation biology and management.Read moreRead less
Sex is important in adaptation to environmental change. Aims: This project will use novel experiments with the aim of determining the potential for plasticity to be adaptive with sexual selection and how non-genetic effects transfer across generations by establishing genomic mechanisms. Significance: Plasticity (or acclimation) is often hailed as the saviour for species in the face of rapid climate change, but it is problematic if it is not adaptive in nature. Expected outcomes: Expected outcome ....Sex is important in adaptation to environmental change. Aims: This project will use novel experiments with the aim of determining the potential for plasticity to be adaptive with sexual selection and how non-genetic effects transfer across generations by establishing genomic mechanisms. Significance: Plasticity (or acclimation) is often hailed as the saviour for species in the face of rapid climate change, but it is problematic if it is not adaptive in nature. Expected outcomes: Expected outcomes include an enhanced ability to predict adaptation of fish under environmental change. Benefits: This project will provide significant benefits to Australian and international communities that rely on fish for nutrition, economic and social values, through an improved evidence base to inform management.Read moreRead less
Mapping climate change vulnerability of older Australians to extreme heat. Exposure to extreme heat is associated with negative health outcomes and has been recognized as a global health challenge in the context of climate change, especially among older people. While the direct heat-related mortality for older people reached a record high of 345,000 deaths worldwide in 2019, which was 80.6% higher than the 2000–05 average, there has been no detailed study in Australia. This project is to have a ....Mapping climate change vulnerability of older Australians to extreme heat. Exposure to extreme heat is associated with negative health outcomes and has been recognized as a global health challenge in the context of climate change, especially among older people. While the direct heat-related mortality for older people reached a record high of 345,000 deaths worldwide in 2019, which was 80.6% higher than the 2000–05 average, there has been no detailed study in Australia. This project is to have a national picture of the impact of extreme heat on the health outcomes of older people and associated healthcare costs at Statistical Area level 3 (SA3), to inform the design and implementation of tailored interventions to minimize the health risk and costs from extreme heat to protect the health of this vulnerable group.

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
