The overarching aim of this project is to advance knowledge on the long-term impacts of ocean acidification on marine fish and fisheries. An interrelated set of projects will be developed that tests the capacity of marine fish to adapt to projected future rises in ocean carbon dioxide and will investigate the effects of ocean acidification on apex predators and key fisheries species. The research will address critical knowledge gaps in ocean acidification research and provide advice about the impacts of ocean acidification on marine biodiversity and fisheries productivity on time scales relevant to strategic management and policy decision-making in Australia and internationally.Read moreRead less
A changing climate for calcification on the Great Barrier Reef: past, present and future. The Great Barrier Reef (GBR) is a national and international icon, recognised through its inscription as a World Heritage Area and economic and social value to Australians. Maintenance of the GBR as we know it is now compromised by a rapidly changing climate. Ocean acidification, warming water temperatures and increased freshwater will progressively be detrimental to the fundamental reef-building process ....A changing climate for calcification on the Great Barrier Reef: past, present and future. The Great Barrier Reef (GBR) is a national and international icon, recognised through its inscription as a World Heritage Area and economic and social value to Australians. Maintenance of the GBR as we know it is now compromised by a rapidly changing climate. Ocean acidification, warming water temperatures and increased freshwater will progressively be detrimental to the fundamental reef-building process of calcification. Informed policy and management strategies in a rapidly changing physical environment require determination, for short and long time frames, of the regional consequences and impacts of changing reef-building capacity.Read moreRead less

Summary
Macroalgal-driven feedbacks and the dynamics of coral reef ecosystems. Seaweed overgrowth poses one of the greatest threats to coral reefs. This project aims to understand the role of seaweeds in shaping ecological processes on degraded coral reefs. In doing so it will not only identify the processes that maintain and reinforce seaweed dominance on coral reefs, but also identify ways to reverse such states.
Seagrass adaptation and acclimation responses to extreme climatic events. This project aims to advance our understanding of how temperate marine plants in their northern limit will respond to the effects of synergistic stressors from extreme events combined with climate change. The project will study Shark Bay, a UNESCO World Heritage site, where a semi-permanent, salinity gradient maintained by shallow seagrass banks has resulted in unique ecosystems like stromatolites to persist. Expected outc ....Seagrass adaptation and acclimation responses to extreme climatic events. This project aims to advance our understanding of how temperate marine plants in their northern limit will respond to the effects of synergistic stressors from extreme events combined with climate change. The project will study Shark Bay, a UNESCO World Heritage site, where a semi-permanent, salinity gradient maintained by shallow seagrass banks has resulted in unique ecosystems like stromatolites to persist. Expected outcomes include practical solutions for building resilience to climate change mitigation in marine ecosystems. This will benefit the broader Australian community through changing how we manage significant resources and services these systems support, such as fisheries, coastal protection.Read moreRead less

Summary
Science for management of coral reefs. This project will lead an international team to undertake a novel, multi-disciplinary program of research on coral reefs to better understand and avoid dangerous ecological tipping points. This research will cement Australia’s leading contribution to reef science, and will guide the management and sustainable use of ecosystems around the world.
Phenotypic and adaptive responses to environmental change. This project aims to investigate how environmental change will effect coral reef fish by assessing adaptive responses in a model species. This project expects to generate new knowledge on the interplay between adaption and plasticity both within and across generations using novel experimental designs. Expected outcomes include improved models of fish acclimation and adaptation to environmental change and an enhanced evidence base to info ....Phenotypic and adaptive responses to environmental change. This project aims to investigate how environmental change will effect coral reef fish by assessing adaptive responses in a model species. This project expects to generate new knowledge on the interplay between adaption and plasticity both within and across generations using novel experimental designs. Expected outcomes include improved models of fish acclimation and adaptation to environmental change and an enhanced evidence base to inform the management of cumulative impacts. This will provide significant benefits to Australian and international communities that rely on fish for nutrition, economic and/or social value.Read moreRead less
An integrated examination of the drivers of movements of large filter feeding organisms of high ecotourism value: a case study. This aim is to define key drivers behind movements of large filter-feeding organisms, using the manta ray as a model system. As dive eco-tourism often depends on the presence of such charismatic filter-feeding animals, an understanding of why animals occupy particular sites at particular times is important, especially in the face of climate change.
The effect of native invasions on Australian fisheries species. This project aims to forecast climate-related changes in the diversity, distribution and abundance of fisheries species. In a changing world where many people depend on oceans for food and livelihood, predicting the future distribution of fisheries species is a challenge. Native invasions and ocean warming are stressing inshore fisheries species, but rigorous empirical data and models that can reliably forecast these effects are lac ....The effect of native invasions on Australian fisheries species. This project aims to forecast climate-related changes in the diversity, distribution and abundance of fisheries species. In a changing world where many people depend on oceans for food and livelihood, predicting the future distribution of fisheries species is a challenge. Native invasions and ocean warming are stressing inshore fisheries species, but rigorous empirical data and models that can reliably forecast these effects are lacking. This project intends to reveal the drivers of successful native invasions, evaluate their effect on fish diversity and productivity, and develop holistic models that forecast their effects on inshore fisheries species’ near-future distribution and stocks.Read moreRead less
Habitat fragmentation: critical role in the decline and recovery of coral reef fish biodiversity. Preserving biodiversity in the face of environmental degradation and climate change is the greatest challenge of our time. Although habitat fragmentation is considered a key cause of the current extinction crisis, the effects of changing habitat configuration on species persistence and recovery is almost completely unknown. Coral reefs are among the most diverse and threatened ecosystems on the plan ....Habitat fragmentation: critical role in the decline and recovery of coral reef fish biodiversity. Preserving biodiversity in the face of environmental degradation and climate change is the greatest challenge of our time. Although habitat fragmentation is considered a key cause of the current extinction crisis, the effects of changing habitat configuration on species persistence and recovery is almost completely unknown. Coral reefs are among the most diverse and threatened ecosystems on the planet and this project will provide the first insights into how coral reef fish diversity responds to increased subdivision and isolation of reef habitat. It will identify critical aspects of habitat change that either enhance local diversity or threaten populations with extinction and provide new ecological data to refine conservation strategies.Read moreRead less
Living in a changing climate: the impacts of temperature during aestivation on burrowing frogs. Although arid zones of Australia are characterised by extremes of temperature, little is known about the thermal ecology of frogs inhabiting these regions. This project will determine the effects of temperature on the physiology of an arid-adapted frog and determine whether likely increases in global temperatures will impact its survival.
