This project aims to determine the ecological effects of artificial light at night on coastal marine ecosystems. Artificial light at night is a pervasive stressor that disrupts a fundamental driver of ecological and evolutionary processes: natural light cycles. Using a holistic approach that combines field experiments and microbial ecology, this project will assess impacts of artificial light at multiple levels of biological and ecological organisation. Expected outcomes include new knowledge on how species interactions mediate functional changes in response to an emergent, global stressor. This should provide significant benefits, including enhanced management of coastal systems and the critical services and social benefits they provide.

Resolving the threat of ocean deoxygenation to coral resilience. This project aims to uncover the role low oxygen plays in shaping healthy corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs, yet we have no knowledge of how less oxygen availability affects critical life history factors that govern coral resilience: growth, reproduction, and stress tolerance. This project unites a multidisciplinary team of experts to, for the fir ....Resolving the threat of ocean deoxygenation to coral resilience. This project aims to uncover the role low oxygen plays in shaping healthy corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs, yet we have no knowledge of how less oxygen availability affects critical life history factors that govern coral resilience: growth, reproduction, and stress tolerance. This project unites a multidisciplinary team of experts to, for the first time, couple advanced oxygen sensing, metabolic physiology, coral reproductive and stress biology to transform our understanding of oxygen thresholds that are diagnostic of reduced coral competitive fitness across life stages (adults, juveniles, larvae), needed to improve coral reef ecosystem management.Read moreRead less
Understanding snow gum dieback for effective and integrated management. The project leverages recent research and infrastructure investments and our determined and collaborative team as it aims to: 1) assess the future geography of snow gum dieback in the high country and identify priority locations for pro-active management, 2) quantify the impact of snow gums on high country water and carbon budgets and thus the socio- economic and biodiversity values, and 3) determine options for mitigation. ....Understanding snow gum dieback for effective and integrated management.

Dieback of our iconic snow gum forests is diminishing the ecological, hydrological and cultural values of the Australian Alps and will impact state and national water-supply and power-generation systems. Our research will inform Alps-wide management efforts designed for long-term success.Read moreRead less
Feast or famine: how Australian plants stay productive under low phosphorus. Phosphorus (P) is in low supply in soils around the nation, and limits plant production in the Australian landscape, as well as for many tropical forests worldwide. How scarce P restricts photosynthetic capacity has remained elusive. We will determine how Australian plants achieve high phosphorus-use efficiency despite low P concentrations in leaves and soils. We will synthesise knowledge of how plants maintain producti ....Feast or famine: how Australian plants stay productive under low phosphorus. Phosphorus (P) is in low supply in soils around the nation, and limits plant production in the Australian landscape, as well as for many tropical forests worldwide. How scarce P restricts photosynthetic capacity has remained elusive. We will determine how Australian plants achieve high phosphorus-use efficiency despite low P concentrations in leaves and soils. We will synthesise knowledge of how plants maintain productivity with low P availability, and inform global models how to represent P biogeochemistry and photosynthesis to improve C-cycle estimates. The understanding of plant photosynthetic and P-saving mechanisms that emerge should provide benefits through improved ecological models and enhanced management of primary production.Read moreRead less

Summary
Animal cultures and anthropogenic change. This project aims to investigate the impacts of anthropogenic change on the elaborate song cultures of declining Australian songbirds. Culture is fundamental to the biology of social animals, and has profound implications for biodiversity conservation; however, the drivers of animal cultural change are unclear. This project will analyse how lyrebird song cultures respond to anthropogenic environmental change, including Australia’s 2019-20 megafires. Furt ....Animal cultures and anthropogenic change. This project aims to investigate the impacts of anthropogenic change on the elaborate song cultures of declining Australian songbirds. Culture is fundamental to the biology of social animals, and has profound implications for biodiversity conservation; however, the drivers of animal cultural change are unclear. This project will analyse how lyrebird song cultures respond to anthropogenic environmental change, including Australia’s 2019-20 megafires. Furthermore, it will assess the mechanisms linking environmental and cultural change, and examine the utility of vocal cultures as bioindicators of ecological health. This project will advance fundamental research in animal culture and enhance the conservation of cultural diversity in the wild.Read moreRead less

Resolving the role of kelp in blue carbon cycles to enable management. We aim to uncover how kelp forests contribute to carbon storage, biodiversity enhancement and nutrient mitigation in Australia. We will combine mapping and modelling to identify local variation in kelp carbon stocks and sequestration potential and verify kelp carbon export to deep ocean sinks through genetic tracing in seawater and sediments. Co-benefits will be identified through nutrient experiments and reef surveys. We wil ....Resolving the role of kelp in blue carbon cycles to enable management. We aim to uncover how kelp forests contribute to carbon storage, biodiversity enhancement and nutrient mitigation in Australia. We will combine mapping and modelling to identify local variation in kelp carbon stocks and sequestration potential and verify kelp carbon export to deep ocean sinks through genetic tracing in seawater and sediments. Co-benefits will be identified through nutrient experiments and reef surveys. We will also assess the risk that calcification and production of halogenic gas within the kelp forest could offset its climate mitigation potential. Project outcomes will enable management to consider kelp ecosystem services broadly and optimize our capacity to meet current emission reduction and biodiversity commitments.Read moreRead less

The global importance and demand for seafood is higher than ever; yet, sustainable seafood production is threatened by seafood fraud. This research will develop a new technology that will trace the geographic origins of seafood from catch to table and empower authorities to combat fraud. In doing so, this research will use natural chemical variation in biominerals to build maps of ocean chemistry and create universal markers of seafood provenance. These markers will be intrinsically tamper-proof: enabling the chemical geolocation of seafood across international trade routes. The outcome of this research will address a global environmental challenge and, in doing so, deliver benefits to the Australian economy, consumer and environment. Read moreRead less
