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.

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
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.

Summary
Evolutionary and environmental basis of CO2 tolerance in coral reef fishes. This project aims to examine the effects of ocean acidification on coral reef fishes due to increasing atmospheric carbon dioxide (CO2). Physiological performance of fish vary under elevated CO2, but behaviour is consistently, negatively impacted. This project aims to investigate evolutionary trade-offs between behaviour and performance, physiological mechanisms key to compromising, maintaining, or enhancing metabolic pe ....Evolutionary and environmental basis of CO2 tolerance in coral reef fishes. This project aims to examine the effects of ocean acidification on coral reef fishes due to increasing atmospheric carbon dioxide (CO2). Physiological performance of fish vary under elevated CO2, but behaviour is consistently, negatively impacted. This project aims to investigate evolutionary trade-offs between behaviour and performance, physiological mechanisms key to compromising, maintaining, or enhancing metabolic performance under elevated CO2, and the importance of habitat in how fish respond to elevated CO2. As fish play critical roles in marine ecosystems by structuring food webs and driving ecological processes, this information will be critical for predicting the effects of ocean acidification on marine ecosystems and biodiversity.Read moreRead less
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
An integrated mechanistic model of species' responses to environmental change: from individual responses to range shifts and beyond. To effectively adapt to future environmental change, reliable forecasts are needed of how human alterations to climate and habitat will affect species. This project integrates cutting-edge methods in nutritional, physiological and spatial ecology to develop new tools for predicting and understanding how species will respond to environmental change.
The failure-threshold of leaves in drought. This project aims to reveal how specific water-stress thresholds damage the leaves of Australian crop and forest species during drought. Water stress affects agricultural productivity and plant survival in drought-prone regions such as Australia. Using optical and X-ray techniques, this project seeks to visualise and quantify the dynamic processes of damage and repair in leaves under stress. Anticipated outputs include a practical basis to predict drou ....The failure-threshold of leaves in drought.

Summary
The quick and the dead: identifying mechanisms for plant drought survival. This project aims to identify genes that control plant responses to low air humidity, which enhance drought survival by restricting water loss. Most plant water loss occurs through pores called stomata. This project expects to identify the genes that close stomata within minutes of decreased humidity by determining the molecular changes that occur over this timeframe and testing candidate genes for a critical role.

This project aims to identify genes that control plant responses to low air humidity, which enhance drought survival by restricting water loss. Most plant water loss occurs through pores called stomata. This project expects to identify the genes that close stomata within minutes of decreased humidity by determining the molecular changes that occur over this timeframe and testing candidate genes for a critical role. Diverse land plant models will be examined to ensure broad applicability of results. A major expected outcome is new knowledge of genes that minimise plant water loss, which would ultimately benefit plant-based industries through new targets for breeding improved, drought-adapted varieties for food security in a drying climate.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
Fires, black carbon, greenhouse gas emissions and the carbon balance of southern sclerophyll forests. Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon.

Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon. An aim of management is to identify fire regimes that will optimise the carbon outcome as well as provide protection to life and property. This project will help managers meet that aim by developing a quantitative understanding of how much stable, black carbon (charcoal) is produced and how it affects other soil processes.Read moreRead less
