Photosynthetic traits as “key performance indicators” of coral health. The objective of this project is to advance knowledge on the healthy functioning of the coral–algal symbiosis, which defines the response of coral reef ecosystems to worldwide environmental change. Current approaches to address this problem have linked coral health to algal symbiont diversity but have been unable to resolve the fundamental symbiont functional traits that govern this link – the “key performance indicators (KPI ....Photosynthetic traits as “key performance indicators” of coral health. The objective of this project is to advance knowledge on the healthy functioning of the coral–algal symbiosis, which defines the response of coral reef ecosystems to worldwide environmental change. Current approaches to address this problem have linked coral health to algal symbiont diversity but have been unable to resolve the fundamental symbiont functional traits that govern this link – the “key performance indicators (KPIs)”. This project plans to couple advanced physiological and functional genomics techniques to transform our understanding of how algal symbiont metabolic KPIs regulate coral growth and stress susceptibility. This may provide new diagnostic capability for the assessment of coral health and may enable us to improve coral reef ecosystem management.Read moreRead less
Chemical signalling in the sea. This project aims to understand how eggs attract and select sperm, and how the environment influences these interactions. Differential sperm chemotaxis, a form of mate choice involving chemical signalling between eggs and sperm, has only been described in mussels, but may be a widespread form of gamete-level sexual selection. The project will study the biochemical and molecular basis of differential sperm chemotaxis in mussels, and the stability of gamete-level in ....Chemical signalling in the sea.

The project will study the biochemical and molecular basis of differential sperm chemotaxis in mussels, and the stability of gamete-level interactions under different environmental conditions. Improved fundamental knowledge of reproduction in a commercially important marine species may yield future commercial benefits for Australia’s marine food production sectorRead moreRead less
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.

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
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
Mechanisms underlying crop pollinator effectiveness in agro-ecosystems. This project aims to understand how pollinators affect fruit quantity and quality. Worldwide, insect pollinators contribute to biodiversity and ecosystem services in production systems, but also cause yield variability in pollinator-dependent crops. Accounting for the combined outcomes of the amount, quality and timing of the pollen transferred by each pollinator visit is a critical but unexplored component of crop pollinati ....Mechanisms underlying crop pollinator effectiveness in agro-ecosystems. This project aims to understand how pollinators affect fruit quantity and quality. Worldwide, insect pollinators contribute to biodiversity and ecosystem services in production systems, but also cause yield variability in pollinator-dependent crops. Accounting for the combined outcomes of the amount, quality and timing of the pollen transferred by each pollinator visit is a critical but unexplored component of crop pollination ecology. This project will quantitatively assess the effectiveness of pollinator communities to determine the importance of pollinator community composition to maximising crop production. This project is expected to protect food resources and economically benefit Australia.Read moreRead less
Testing metabolic theories in ecology. There are striking similarities in the way plants and animals take up and use energy (metabolism), despite enormous variation in size and life-style. This project will make the first experimental comparison of the predictions of the two major theories for these broad patterns. The results will significantly progress this controversial and exciting field.
Functional links between estuaries and their catchments: How does land use change affect estuarine ecological and bio-geochemical function? Estuaries are iconic recreational areas of high ecological and socio-economic value. Estuarine health is strongly linked to the catchments that feed them, yet we have no detailed understanding of these links. This project will use a number of state of the art approaches to better understand how land use affects estuarine health.

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.

The origins of electroreception and nocturnality in the earliest known jawed vertebrates and their bearing on vertebrate diversification. This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision.

This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on tropical reefs or rainforest communities, through careful temporal niche partitioning where reliance on other sensory systems takes over from vision and olfaction as the principal method of prey detection. This project aims to elucidate how the modern fish diversity was shaped by such significant early evolutionary events.Read moreRead less
