The impact of environmental change on larval energetics of molluscs on the southeast coast of Australia. This project will investigate the impact of environmental change on larval energetics of molluscs on the southeast (SE) coast of Australia. The SE coast of Australia is a climate hotspot characterised by rising ocean temperatures, fluctuations in salinity and we expect in the near future ocean acidification (OA). Mollusc larvae show extreme sensitivity to OA, but the impacts of other stressor ....The impact of environmental change on larval energetics of molluscs on the southeast coast of Australia. This project will investigate the impact of environmental change on larval energetics of molluscs on the southeast (SE) coast of Australia. The SE coast of Australia is a climate hotspot characterised by rising ocean temperatures, fluctuations in salinity and we expect in the near future ocean acidification (OA). Mollusc larvae show extreme sensitivity to OA, but the impacts of other stressors remains unknown. It is predicted that OA will reduce the capacity of larvae to cope with temperature and salinity, particularly when food supply is low and in populations which have had no previous exposure to OA. Understanding the response of mollusc larvae to environmental change will support ecologically and economically significant mollusc populations over this century.Read moreRead less
Seafood safety: high throughput diagnostics for ciguatoxin risk assessment. This project aims to develop a novel, high throughput platform for rapidly assessing ciguatoxins. Species of the marine microalgae Gambierdiscus produce ciguatoxins, which accumulate in fish through marine food chains to cause the often debilitating human illness called ciguatera fish poisoning. Ciiguatera fish poisoning is a growing and substantial risk for the $2.2 billion Australian commercial fishing industry. This s ....Seafood safety: high throughput diagnostics for ciguatoxin risk assessment. This project aims to develop a novel, high throughput platform for rapidly assessing ciguatoxins. Species of the marine microalgae Gambierdiscus produce ciguatoxins, which accumulate in fish through marine food chains to cause the often debilitating human illness called ciguatera fish poisoning. Ciiguatera fish poisoning is a growing and substantial risk for the $2.2 billion Australian commercial fishing industry. This serious illness is increasingly impacting more southerly areas of Australia due to environmental changes. The outcomes of this project include new knowledge of the risk of ciguatoxins at Australian 'hot spot' sites, extensively field tested methods for detecting Gambierdiscus and ciguatoxins in situ and key data to inform policy to safeguard the seafood industry and consumers.

Rewiring marine food webs: Predicting consequences of species range shifts. This project aims to predict how changes in climate-driven species distributions affect shallow marine communities globally. Environmental change affects the structure, resilience and productivity of coastal marine ecosystems at regional and global scales. This project will combine global species distribution and trait databases, existing experimental data and targeted field sampling to develop, test and apply an integra ....Rewiring marine food webs: Predicting consequences of species range shifts. This project aims to predict how changes in climate-driven species distributions affect shallow marine communities globally. Environmental change affects the structure, resilience and productivity of coastal marine ecosystems at regional and global scales. This project will combine global species distribution and trait databases, existing experimental data and targeted field sampling to develop, test and apply an integrated modelling platform to predict how global warming-driven changes in species distributions and their interactions affect the structure and dynamics of shallow marine communities. This project addresses a knowledge gap on how species’ redistributions and trophic dynamics produce communities, and aims to forecast future species abundances for sustainable marine ecosystem management.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

A coupled liquid chromatography mass spectrometer as a core component of an Australian research facility for marine microbial biotoxins: This project will establish an Australian research facility for marine microbial biotoxins. The requested core instrument is a liquid chromatography mass spectrometer to analyse and quantify microbial toxins at ultra-trace quantities against complex sample backgrounds. Specialists in diverse areas of marine ecology and chemistry from three partner universities will team up to focus their research on novel biotoxins and marine natural products. This research is significant in developing a capability to swiftly respond to the emergence and outbreak of novel toxins. This facility will foster the collaboration with the partner organisation, the Cawthron Institute, a world leading research institute of marine biotoxins.Read moreRead less
Future fisheries under climate change: the missing role of zooplankton. This project aims to develop the first global ecosystem model with a more realistic representation of zooplankton. Fish are the main source of protein for 3 billion people, yet fish catches are declining. Current models of future fish biomass under climate change do not consider the complex role that zooplankton play in transferring energy from phytoplankton to fish. By resolving the link between phytoplankton and fish, this ....Future fisheries under climate change: the missing role of zooplankton. This project aims to develop the first global ecosystem model with a more realistic representation of zooplankton. Fish are the main source of protein for 3 billion people, yet fish catches are declining. Current models of future fish biomass under climate change do not consider the complex role that zooplankton play in transferring energy from phytoplankton to fish. By resolving the link between phytoplankton and fish, this project will vastly improve estimates of future global fisheries production and regional variation. Such knowledge is vital for future food security in Australia and globally, and also to understand the role of zooplankton in carbon export in the ocean.Read moreRead less
