Incorporating new knowledge of phytoplankton diversity and nutrient utilisation into an ocean-climate model to improve forecasts of ocean function. Phytoplankton drives ocean biogeochemical cycles and regulate Earth’s climate yet are poorly represented in ocean-climate models. This project will use advanced cell sorting and analysis techniques and innovative selection experiments to gain a deeper understanding of phytoplankton diversity and nutrient utilisation under projected climate change.

Phytoplankton drives ocean biogeochemical cycles and regulate Earth’s climate yet are poorly represented in ocean-climate models. This project will use advanced cell sorting and analysis techniques and innovative selection experiments to gain a deeper understanding of phytoplankton diversity and nutrient utilisation under projected climate change. This new knowledge will be used to improve the biological structure of an existing coupled ocean-climate model and reduce key uncertainties in forecasts of ocean function. This research will provide managers and industry with more accurate insight into the effects of ongoing climate change on the delivery of ecosystem services in eastern Australian waters.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
Integrating biomechanics and ecology: moving from an individual- to population-level understanding of the effects of environmental change. Coral reefs, a key Australian resource, face an uncertain future due to environmental change. Up to now, environmental change research has focused on the individual level, severely limiting our predictive capacity. This project will develop a novel 'first principle' approach to solve this shortcoming and make population-level predictions possible.
Are good males bad females? Sexual conflict in hermaphrodites. Animal hermaphrodites (organisms that are both males and females) are extremely common and important from both an economic and ecological perspective but we know little about the evolution of this group. This project will examine how sexual conflict, so pervasive in organisms with separate sexes, affects the evolution of hermaphrodites.

Summary
Regime shifts from kelp forests to turfs: drivers, resilience and future. This project aims to apply a comparative experimental and analytical approach to quantify linkages among multiple stressors driving kelp forest loss and expansion of turfs across three continents. Transformations of kelp forests to turf reefs are associated with a profound loss of ecological productivity and function, with significant impacts for societies reliant on the biodiversity and functioning of kelp ecosystems. Fie ....Regime shifts from kelp forests to turfs: drivers, resilience and future. This project aims to apply a comparative experimental and analytical approach to quantify linkages among multiple stressors driving kelp forest loss and expansion of turfs across three continents. Transformations of kelp forests to turf reefs are associated with a profound loss of ecological productivity and function, with significant impacts for societies reliant on the biodiversity and functioning of kelp ecosystems. Field and laboratory experiments will be used to develop and test ‘green gravel’, a novel restoration tool that aims to overcome reinforcing feedbacks (lack spores and hard substrate) preventing recovery of kelp forests. This will provide significant benefits by identifying solutions to address loss of kelp forests in Australia and globally.Read moreRead less

Summary
Ecology of novel coral reef ecosystems. Coral reef ecosystems are changing. Some of these changes are predictable, based on how species respond to climate change. This project will utilise information on species vulnerability to predict what reef ecosystems, including corals, fishes and invertebrates, will look like in the future and how this will affect the benefits we gain from reefs.

Summary
A transportable containerised laboratory for rapid cell sorting and high-resolution bioimaging of living aquatic microbes in field locations. This project will deliver a transportable, unique laboratory for the rapid isolation and high-resolution analysis of living microbes immediately after sampling from the sea or waterways. It will be the first of its kind in Australia and deliver new knowledge of the role of these organisms in their natural habitats.
Ecological competition between corals and algae in a high carbon dioxide world: understanding the mechanisms and implications for reef ecosystems. This project will explore the impacts of ocean acidification on ecological interactions between two key groups on reefs: corals and seaweeds. Such knowledge is fundamental to managing the consequences of increased global carbon emissions on the ecology and persistence of Australian marine ecosystems, including the Great Barrier Reef.

Summary
Trait plasticity and the maintenance of functional diversity. This project aims to determine if trait plasticity mediates functional degradation of coral reefs. It will use natural environmental gradients to identify mechanisms that enable corals to persist in marginal habitats. The project will use three-dimensional imaging to measure how variability in traits influences functional redundancy. This will facilitate better predictions of the effects of environmental change on reef systems. Expect ....Trait plasticity and the maintenance of functional diversity. This project aims to determine if trait plasticity mediates functional degradation of coral reefs. It will use natural environmental gradients to identify mechanisms that enable corals to persist in marginal habitats. The project will use three-dimensional imaging to measure how variability in traits influences functional redundancy. This will facilitate better predictions of the effects of environmental change on reef systems. Expected outcomes include improved understanding of the response of coral reef ecosystems to environmental change and a framework for predicting reefs at risk of degradation. Benefits will be to both global biodiversity conservation and the provision of ecosystem services in reef dependent communities.Read moreRead less
Advancing knowledge of microbial symbioses underpinning coral health and reef resilience and predicting their responses to climate change. Coral reefs are complex, diverse ecosystems in which microbial communities form associations with host corals. However, the roles these associations play in coral stress responses are unknown. This project unlocks the black-box of coral microbial complexity and determines how the reef’s smallest members have the greatest influence on reef health.
