Resilience of eucalypts to future droughts. This project aims to examine how resilient Eucalyptus species are to future droughts by combining data synthesis, manipulative experiments and modelling. Climate change is expected to increase the frequency, magnitude and duration of future droughts, with major environmental and socio-economic consequences for Australia. Current predictive capacity is extremely limited: experiments are limited in scale and cannot capture important global change interac ....Resilience of eucalypts to future droughts. This project aims to examine how resilient Eucalyptus species are to future droughts by combining data synthesis, manipulative experiments and modelling. Climate change is expected to increase the frequency, magnitude and duration of future droughts, with major environmental and socio-economic consequences for Australia. Current predictive capacity is extremely limited: experiments are limited in scale and cannot capture important global change interactions, whilst models do not represent the functional characteristics and adaptions of eucalypts. This project will develop a strong evidence- and process-based understanding to quantify the functional behaviour of drought-adapted Eucalyptus species and leverage this insight to make future model projections.Read moreRead less
Understanding the mechanisms of thermal acclimation in the symbiotic algae (Symbiodinium) within cnidarian corals. Global warming is a major threat to coral reefs, contributing to devastating coral bleaching. This project will provide new insight into how coral reefs can respond to rising global temperature through clarifying the thermal acclimation mechanisms in corals using molecular techniques.
To grow or to store: Do plants hedge their bets? This project aims to resolve a long-standing question about the function of perennial plants: how much of the carbon taken up by photosynthesis is used immediately for growth, and how much is kept in reserve as insurance against future stress? This question is important to our understanding of how plants respond to stresses such as severe drought, and yet lack of data and theoretical modelling currently hampers our ability to answer it. By applyin ....To grow or to store: Do plants hedge their bets? This project aims to resolve a long-standing question about the function of perennial plants: how much of the carbon taken up by photosynthesis is used immediately for growth, and how much is kept in reserve as insurance against future stress? This question is important to our understanding of how plants respond to stresses such as severe drought, and yet lack of data and theoretical modelling currently hampers our ability to answer it. By applying novel data analysis and modelling tools to recent experimental results, the project plans to test hypotheses for how plants allocate carbon between growth and storage in response to stress. Insights from the project may underpin better management of Australia’s vulnerable ecosystems.Read moreRead less
Coping with temperature extremes: morphological constraints on leaf function in a warmer, drier climate. This project will determine how hydraulic properties of temperate, evergreen leaves affect their capacity to cope with seasonal variation in temperature extremes. The results will enhance mechanistic understanding of temperature tolerance, and inform prediction of vegetation change in response to climate warming and increasing CO2 concentrations.
Fiddling while home burns: climate change and fiddler crabs. Climate change is already affecting many Australian animals, including fiddler crabs. This project will use extensive knowledge of fiddler crab biology to determine whether they can behaviourally compensate for the rapid changes that are occurring by using experiments and observations conducted under natural conditions in the mangroves of Darwin harbour.
Portfolio projection of biodiversity responses under climate change. Organisms need to adapt and/or migrate to avoid critical population loss under climate change. Despite the importance of both processes in biodiversity dynamics, most biodiversity predictions focus on the patterns of migration under climate change. The type and amount of adaptation required to escape climate-driven extinction in the future remain largely unknown. This project aims to quantify the type and extent of adaptation a ....Portfolio projection of biodiversity responses under climate change. Organisms need to adapt and/or migrate to avoid critical population loss under climate change. Despite the importance of both processes in biodiversity dynamics, most biodiversity predictions focus on the patterns of migration under climate change. The type and amount of adaptation required to escape climate-driven extinction in the future remain largely unknown. This project aims to quantify the type and extent of adaptation and migration required for ecologically and economically important marine species to avoid critical population loss under climate change. By quantifying adaptive and migration responses as vulnerability metrics, the project outcomes will provide resource managers novel tools to formulate flexible management strategies.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?

Prioritising habitat restoration for biodiversity and ecosystem service outcomes. An emerging carbon market will provide funds for habitat restoration over the coming decades, but this will only be realised through careful prioritisation and planning. This research will prioritise investments in habitat restoration in order to cost-effectively achieve biodiversity conservation and ecosystem service protection goals.

Engineering microbes that increase coral climate resilience. This project aims to develop microbes which are able to enhance the climate resilience of corals. Coral reefs around the world are being lost at an alarming rate. Developing microbial symbionts to enhance coral climate resilience will give Australian and other coral reef ecosystems an increased chance of surviving the impact of climate change.

This project aims to develop microbes which are able to enhance the climate resilience of corals. Coral reefs around the world are being lost at an alarming rate. Developing microbial symbionts to enhance coral climate resilience will give Australian and other coral reef ecosystems an increased chance of surviving the impact of climate change. The project will also enhance understanding of the functional roles of microbial symbionts of corals, and advance the microbial symbiosis discipline globally. Expected outcomes include healthier coral reefs through the use of more climate resilient coral stock in reef conservation and restoration initiatives.Read moreRead less
Avoiding coral bleaching: investigation into the repair of damaged photosynthetic machinery in symbiotic algae (symbiodinium) within corals. Photosynthesis in symbiotic algae within corals is essential for a healthy alga-coral symbiotic relationship. This project will provide new insights into how symbiotic algae maintain higher photosynthetic performance in corals through elucidating the mechanism associated with the repair of photodamaged photosynthetic machinery.
