Identifying factors that counter negative impacts of ocean climate change. 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 allo ....Identifying factors that counter negative impacts of ocean climate change. 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
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.
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

Bridging the land–sea divide to ensure food security under climate change. This project aims to comprehensively evaluate ocean-based food solutions to meet food security needs under climate change. It will resolve a critical blind spot in current plans that isolate land and sea food systems and neglect their interdependencies. Combining global models and data, it will assess the constraints of ocean-based food solutions by anticipating and accounting for land-sea links including: agricultural ru ....Bridging the land–sea divide to ensure food security under climate change. This project aims to comprehensively evaluate ocean-based food solutions to meet food security needs under climate change. It will resolve a critical blind spot in current plans that isolate land and sea food systems and neglect their interdependencies. Combining global models and data, it will assess the constraints of ocean-based food solutions by anticipating and accounting for land-sea links including: agricultural runoff, shared feed resources for farmed animals, and trade-offs for biodiversity and climate mitigation. It will deliver a major leap in our capacity to undertake holistic ecosystem assessment of future food production pathways. Benefits will include integrated food–biodiversity–climate policies for Australia and the world.Read moreRead less

Will trees get enough nitrogen to sustain productivity in elevated CO2? The project proposes to explore how tissue nitrogen declines in future elevated carbon dioxide (eCO2) by studying the availability of soil nitrogen to plants and use of nitrogen by Eucalyptus woodland trees. Plant canopy nitrogen concentrations decline in nearly every large-scale eCO2 study done on native soils. The project plans to explore how changes in ecosystem nitrogen balance occur, by investigating if leaf nitrogen de ....Will trees get enough nitrogen to sustain productivity in elevated CO2? The project proposes to explore how tissue nitrogen declines in future elevated carbon dioxide (eCO2) by studying the availability of soil nitrogen to plants and use of nitrogen by Eucalyptus woodland trees. Plant canopy nitrogen concentrations decline in nearly every large-scale eCO2 study done on native soils. The project plans to explore how changes in ecosystem nitrogen balance occur, by investigating if leaf nitrogen declines under eCO2 due to the balance of plant activity versus changes in soil nitrogen availability. The outcomes are central to knowing the extent to which extra nitrogen ‘feeds’ the eCO2 fertilisation response and sustains long-term increases in productivity. Expected outcomes may support the development of management options to sustain future forest productivity.Read moreRead less
