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
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
Eucalypt growth in past and future environments - a novel approach to understanding the impacts of atmospheric CO2 and climate. The impact of climate change and rising atmospheric CO2 on Australia's plantation and native forests is a major concern for government and land managers. These forests are important for environmental, aesthetic, and economic purposes, including carbon sequestration and trading. Forests use large amounts of water, reducing stream flow and water supplies for rural and u ....Eucalypt growth in past and future environments - a novel approach to understanding the impacts of atmospheric CO2 and climate. The impact of climate change and rising atmospheric CO2 on Australia's plantation and native forests is a major concern for government and land managers. These forests are important for environmental, aesthetic, and economic purposes, including carbon sequestration and trading. Forests use large amounts of water, reducing stream flow and water supplies for rural and urban communities. Knowledge generated from the proposed project will provide insight into mechanisms driving productivity and water use of forests in current and future environments. The knowledge will be used by land managers and government to develop strategies to cope with future impacts of climate change.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.
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.
Quantifying tree and soil respiration and their responses to global change. The Australian Greenhouse Office, as well as independent analysis, recognizes that belowground processes must be better quantified if Australia's contributions to atmospheric concentrations of greenhouse gases (GG) are to be firmly based. A major issue is the lack of dedicated research focused on soil and plant root emissions of GG and, in particular, a lack of testing of methodologies suited to Australian soils and con ....Quantifying tree and soil respiration and their responses to global change. The Australian Greenhouse Office, as well as independent analysis, recognizes that belowground processes must be better quantified if Australia's contributions to atmospheric concentrations of greenhouse gases (GG) are to be firmly based. A major issue is the lack of dedicated research focused on soil and plant root emissions of GG and, in particular, a lack of testing of methodologies suited to Australian soils and conditions. This project will address these concerns. We will also be addressing the clear need for further training of PhD qualified researchers in the field of climate change. Read moreRead less
How will Eucalypt tree architecture and growth adapt to future atmospheric CO2 and drought? This work is fundamental to understanding how growth and water use by Australia's forests will be modified in the future by global change. The changes in tree leaf area and canopy structure that we seek to understand will determine forest responses to increasing atmospheric CO2 and drought. It is essential to study these changes on Australian species, because they differ from forest species elsewhere in h ....How will Eucalypt tree architecture and growth adapt to future atmospheric CO2 and drought? This work is fundamental to understanding how growth and water use by Australia's forests will be modified in the future by global change. The changes in tree leaf area and canopy structure that we seek to understand will determine forest responses to increasing atmospheric CO2 and drought. It is essential to study these changes on Australian species, because they differ from forest species elsewhere in having been largely shaped by water availability. This fundamental work will flow into predictions of future forest growth and water use in Australia, with consequences for land and water resource management as well as forestry.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.
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?
