Temperate trophic cascades: impacts of seal foraging on benthic community dynamics. Effective Marine Protected Area management across Australia requires guidance from rigorous strategic research. The project will investigate opposing activities that provoke ecosystem collapse (overharvesting, grazing) or recovery (marine park protection) and provide advice to improve effectiveness of marine conservation strategies in New South Wales and South Australia.
Regime change: when and how do ecological subordinates turn dominant? This project aims to bridge the gap between physiology and ecology in kelp forest species by developing mechanistic models to predict change and, in an unprecedented step, test them in long-term experiments at naturally acidified sites to understand the consequences of ocean acidification (OA) and warming for kelp forests. Ecosystem change is a frequent outcome of decadal modifications of the physical and chemical environment. ....Regime change: when and how do ecological subordinates turn dominant? This project aims to bridge the gap between physiology and ecology in kelp forest species by developing mechanistic models to predict change and, in an unprecedented step, test them in long-term experiments at naturally acidified sites to understand the consequences of ocean acidification (OA) and warming for kelp forests. Ecosystem change is a frequent outcome of decadal modifications of the physical and chemical environment. Whilst these changes often involve degradation from productive states, we have a poor understanding of the mechanisms which drive change. Key stressors in marine systems, OA and warming are predicted to drive loss of kelp forests but we still don't understand the reality of these predictions.Read moreRead less
Safeguarding coral reef fisheries for future food security. This Fellowship aims to address the vulnerability of coral reef fisheries in Australia and the Indo-Pacific by identifying fishery targets that benefit human nutrition and will persist despite declining coral habitats and rising water temperature. This project will advance knowledge on coral and fish responses to increasingly frequent marine heatwaves, using novel methodologies rooted in ecological modelling, experimental marine biology ....Safeguarding coral reef fisheries for future food security. This Fellowship aims to address the vulnerability of coral reef fisheries in Australia and the Indo-Pacific by identifying fishery targets that benefit human nutrition and will persist despite declining coral habitats and rising water temperature. This project will advance knowledge on coral and fish responses to increasingly frequent marine heatwaves, using novel methodologies rooted in ecological modelling, experimental marine biology and climate forecasting. Expected outcomes include (i) a comprehensive toolbox for improved management of coral reefs and associated fisheries in Australia and beyond, and (ii) an integrated socio-ecological model for predicting coral reef fishery responses under environmental change.Read moreRead less
Addressing social and ecological constraints to expand marine restoration. This project aims to improve social and ecological outcomes of marine habitat restoration by increasing community and industry engagement in restoration practices with high socio-economic benefits. By understanding and overcoming social and ecological barriers to successful restoration efforts, this project will generate new knowledge on how communities – both human and marine – can work together to rapidly restore robust ....Addressing social and ecological constraints to expand marine restoration. This project aims to improve social and ecological outcomes of marine habitat restoration by increasing community and industry engagement in restoration practices with high socio-economic benefits. By understanding and overcoming social and ecological barriers to successful restoration efforts, this project will generate new knowledge on how communities – both human and marine – can work together to rapidly restore robust, productive reef habitats. Expected outcomes of this project include a new ecological, multi-species approach that boosts restoration resilience; and a collaborative framework for developing government policy that builds industry and community support for cooperative management of coastal ecosystem restoration.Read moreRead less
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
Ocean acidification and rising sea temperature effect on fish. Predictions of climate change effects on marine biodiversity often do not include species interactions. This project will study the effects of climate change stressors on the behaviour and competitive abilities of fishes and build models that predict how these affect their survival and persistence in marine ecosystems under future climate scenarios.
Using ancient fish ear bones to overcome the shifting baseline syndrome in freshwater fish populations. Chemical tracers in fish ear bones from 5,500 years ago through to modern times will provide information on changes in fish ecology over centuries and identify why freshwater fish populations have declined. Outcomes will provide knowledge of how fish populations would react to altered fishing pressure and restoration of environments.
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
Testing co-evolutionary processes driving venom diversity in tiger snakes. Testing co-evolutionary processes driving venom diversity in tiger snakes.

Testing co-evolutionary processes driving venom diversity in tiger snakes. This project aims to examine the geographic variation amongst tiger snakes in anatomy, ecology, and life history traits, and the relationship of these factors to venom toxins and production; and to evaluate the true pharmacological potential of tiger snake venom. This project will investigate the role of venom adaptation in long-term animal evolution, by identifying rare venom transcripts involved in providing evolutionary potential for adaptation to environmental change. This is essential as continuing climatic and human-induced alteration of our environment affects southern Australia where many people live, work and interact with native wildlife. Anticipated outcomes are maximizing venom harvests and enhanced snakebite treatment capacity.Read moreRead less
LIZARD SOCIAL BEHAVIOUR AND THE INFLUENCE OF PARASITES. We ask why stable social group living in animals, with well documented benefits, is relatively rare. One cost is the enhanced opportunity for parasite and disease transmission among group members. We will explore, for a lizard, the impact of group living on parasite infections, and the costs of infection. We expect to produce observational and experimental results with an unusual level of detail, and with a fresh taxonomic perspective to in ....LIZARD SOCIAL BEHAVIOUR AND THE INFLUENCE OF PARASITES. We ask why stable social group living in animals, with well documented benefits, is relatively rare. One cost is the enhanced opportunity for parasite and disease transmission among group members. We will explore, for a lizard, the impact of group living on parasite infections, and the costs of infection. We expect to produce observational and experimental results with an unusual level of detail, and with a fresh taxonomic perspective to influence debate in this central area of behavioural ecology. We will also produce new information on behavioural ecology of Australian fauna, important for conservation management and ecotourism.Read moreRead less
