The role of epigenetic modifications in bovid adaptation to environmental change. This project will explore the role of epigenetic change, where gene expression is regulated without changing the deoxyribonucleic acid (DNA) sequence, in how animals adapt to rapid climate change. This project will trace epigenetic markers in ancient bison and cows through 30,000 years of climate change, and identify key adaptive genes for the cattle industry.

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.
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.
Drought-induced mortality in arid-zone tree species: a mechanistic study. This project aims to determine the relative importance of elevated temperature and increased vapour pressure deficit during drought in causing drought induced mortality (DIM). The outcomes of this project will be an enhanced ability to predict future mortality in response to a warmer and atmospherically drier climate. This will benefit the development of future management strategies and our ability to predict drought impac ....Drought-induced mortality in arid-zone tree species: a mechanistic study.

The outcomes of this project will be an enhanced ability to predict future mortality in response to a warmer and atmospherically drier climate. This will benefit the development of future management strategies and our ability to predict drought impacts on landscape function and productivity.Read moreRead less
Adapting to climate change: does enhanced metabolism provide heritable protection against ocean acidification and increasing temperature in oysters? By the end of this century, our oceans will have much higher concentrations of carbon dioxide and will be several degrees warmer. We have developed a population of oysters that can survive in these conditions, and the project will examine these oysters at the molecular level to determine whether increased metabolism is responsible for their survival ....Adapting to climate change: does enhanced metabolism provide heritable protection against ocean acidification and increasing temperature in oysters?

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
The impact of environmental change on larval energetics of molluscs on the southeast coast of Australia. This project will investigate the impact of environmental change on larval energetics of molluscs on the southeast (SE) coast of Australia. The SE coast of Australia is a climate hotspot characterised by rising ocean temperatures, fluctuations in salinity and we expect in the near future ocean acidification (OA). Mollusc larvae show extreme sensitivity to OA, but the impacts of other stressor ....The impact of environmental change on larval energetics of molluscs on the southeast coast of Australia. This project will investigate the impact of environmental change on larval energetics of molluscs on the southeast (SE) coast of Australia. The SE coast of Australia is a climate hotspot characterised by rising ocean temperatures, fluctuations in salinity and we expect in the near future ocean acidification (OA). Mollusc larvae show extreme sensitivity to OA, but the impacts of other stressors remains unknown. It is predicted that OA will reduce the capacity of larvae to cope with temperature and salinity, particularly when food supply is low and in populations which have had no previous exposure to OA. Understanding the response of mollusc larvae to environmental change will support ecologically and economically significant mollusc populations over this century.Read moreRead less
How does the interaction between environmental drivers determine the impact of global change on animals? There is an urgent need to determine how vulnerable natural populations are to simultaneous changes in more than one environmental driver. This project will take an integrative approach, using molecular, physiological and ecological tools, to determine whether cellular responses to the interaction between UV-B radiation and temperature vary between populations, and within individuals over tim ....How does the interaction between environmental drivers determine the impact of global change on animals? There is an urgent need to determine how vulnerable natural populations are to simultaneous changes in more than one environmental driver. This project will take an integrative approach, using molecular, physiological and ecological tools, to determine whether cellular responses to the interaction between UV-B radiation and temperature vary between populations, and within individuals over time. This project will bridge the gap between physiology and ecology by testing whether molecular responses translate into fitness benefits for the organism to gain an understanding at a level that is relevant for conservation.

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

The aim of this project is to predict how key ecosystem service providers may change under resource limitation and thermal stress. The project seeks to assess how common species respond to climatic fluctuations and resource limitations when competing for resources in familiar and novel environments along six biogeographic transects throughout Australia. In combination with hypothesis-driven field, laboratory and transplant experiments, citizen science will be used to create a longitudinal data set of the constraints put on dominant and functionally important species. The project also seeks to enable more robust forecasting of biological responses to environmental change by integrating both empirical and theoretical capabilities.Read moreRead less
