The ecosystem of the Southern Ocean is extremely complex, and understanding its response to rapid climate change is challenging. The aim of the project is to use changes in the behaviour of marine predators to provide new measures of integrated changes in eastern Antarctic ecosystems throughout the winter. With novel combinations of electronic tagging, natural biogeochemical markers, and simulation modelling, the project expects to reconstruct changes in animal behaviour in response to changes in the environment. The data is anticipated to explain ongoing large-scale shifts in Southern Ocean ecosystems, providing information needed to underpin future management and adaptation strategies.Read moreRead less
The contribution of human/marine herbivore interactions to reef degradation. This project aims to define how interactions between human society and herbivores influence marine ecosystem structure and function. It will analyse geographic patterns from recent systematic sampling of reef communities worldwide and study fish, macro-invertebrate and meso-grazer herbivory to identify herbivores’ role in the collapse and recovery of reef ecosystems. This project will examine the match between a critica ....The contribution of human/marine herbivore interactions to reef degradation. This project aims to define how interactions between human society and herbivores influence marine ecosystem structure and function. It will analyse geographic patterns from recent systematic sampling of reef communities worldwide and study fish, macro-invertebrate and meso-grazer herbivory to identify herbivores’ role in the collapse and recovery of reef ecosystems. This project will examine the match between a critical ecosystem function and community structure across local to global scales, including the identification of non-linearities and interactions involving human effects on this process. This research is expected to safeguard marine ecosystems from collapse.Read moreRead less
Poleward bound: mechanisms and consequences of climate-driven species redistribution in marine ecosystems. Global redistribution of Earth's species is widely recognised as a fingerprint of climate change. However, the physiological and ecological processes that underpin such shifts in the distribution of marine species are poorly understood. Even less is known about why species respond at different rates, and how such widespread changes will impact the structure and function of Australia's marin ....Poleward bound: mechanisms and consequences of climate-driven species redistribution in marine ecosystems. Global redistribution of Earth's species is widely recognised as a fingerprint of climate change. However, the physiological and ecological processes that underpin such shifts in the distribution of marine species are poorly understood. Even less is known about why species respond at different rates, and how such widespread changes will impact the structure and function of Australia's marine ecosystems. This research will address critical knowledge gaps of why and how species respond in vastly different ways to environmental change. Research outcomes will improve the capacity to predict responses of marine species and ecosystems to climate change and provide advice relevant to strategic management of valuable natural resources.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
High resolution health assessment of Antarctic plants as climate changes. Declines in terrestrial ecosystem health as a result of a drying climate have been observed in some areas of East Antarctica. This project aims to determine if such changes are widespread. Since mosses, the dominant plants of Antarctica, preserve a record of past climate down their shoots they can be used as surrogates to study how both ecosystems and climate are changing at remote polar sites. Outcomes will include improv ....High resolution health assessment of Antarctic plants as climate changes. Declines in terrestrial ecosystem health as a result of a drying climate have been observed in some areas of East Antarctica. This project aims to determine if such changes are widespread. Since mosses, the dominant plants of Antarctica, preserve a record of past climate down their shoots they can be used as surrogates to study how both ecosystems and climate are changing at remote polar sites. Outcomes will include improved climate data for Antarctica, enabling more robust analysis of regional climate change, and development of ultrahigh-resolution techniques capable of non-destructively monitoring Antarctic ecosystem health. This research will advance ecosystem science and inform best practice in management of Antarctic biodiversity.Read moreRead less
Predicting biodiversity distribution on the Antarctic continental shelf. This project aims to develop an international database of underwater observations to predict the distribution of seafloor biodiversity over the entire Antarctic continental shelf for the present day and to 2100. Antarctic seafloor communities are unique and highly diverse, but their distribution is poorly known because biological data are sparse. These predictions depend on a unique and validated approach to estimate the pr ....Predicting biodiversity distribution on the Antarctic continental shelf. This project aims to develop an international database of underwater observations to predict the distribution of seafloor biodiversity over the entire Antarctic continental shelf for the present day and to 2100. Antarctic seafloor communities are unique and highly diverse, but their distribution is poorly known because biological data are sparse. These predictions depend on a unique and validated approach to estimate the present and future redistribution of surface primary production to the seafloor, and will enable calculating the amount of atmospheric carbon captured and stored at the seafloor. The maps will be at an unprecedented resolution of around 2 kilometres, and be invaluable tools underpinning policy, management and future science.Read moreRead less
