Summary
When and where are temperate reef communities vulnerable to ocean warming? This project will test in the laboratory and the field, when and where ocean warming will exceed the thermal limits of marine species and why certain species show greater sensitivity to warming temperatures than others. This project expects to generate robust estimates about how temperature sensitivity varies between populations across species’ ranges and identify the ecological implications for habitat loss in areas wher ....When and where are temperate reef communities vulnerable to ocean warming? This project will test in the laboratory and the field, when and where ocean warming will exceed the thermal limits of marine species and why certain species show greater sensitivity to warming temperatures than others. This project expects to generate robust estimates about how temperature sensitivity varies between populations across species’ ranges and identify the ecological implications for habitat loss in areas where thermal limits differ between key species. Expected outcomes include an enhanced capacity to detect when and where vulnerability hotspots will emerge that could jeopardise the immense social, ecological, and economic value of Australia’s temperate reefs, next to which 70% of Australians live, along 8,000 km of coastline.Read moreRead less
Species redundancy in response to multiple disturbances. This project aims to elucidate how the context within which disturbances occur affects food web linkages and how these map to responses in ecosystem function. There is a critical need to test the common assumption in environmental management that high biodiversity makes ecosystems resilient to disturbances. Studies that merely observe biodiversity change after disturbance cannot identify ecological processes connecting high diversity and e ....Species redundancy in response to multiple disturbances. This project aims to elucidate how the context within which disturbances occur affects food web linkages and how these map to responses in ecosystem function. There is a critical need to test the common assumption in environmental management that high biodiversity makes ecosystems resilient to disturbances. Studies that merely observe biodiversity change after disturbance cannot identify ecological processes connecting high diversity and ecosystem function, making experiments that manipulate identical disturbances in ecosystems with different biodiversity essential. This project will use field experiments that manipulate disturbances in streams replicated in low and high biodiversity regions and across gradients of chronic background stress to show how biodiversity sustains functional ecosystems, and how much diversity can be lost before ecosystems collapse.Read moreRead less
Restoring diverse native vegetation using drone-based precision seeding .

This project aims to make drone technology a viable solution for scaling up the restoration of native vegetation on degraded land. By integrating new research in plant ecology, microbiology and environmental economics the project aims to fill key knowledge gaps about the viability and application of drones in restoration. Expected outcomes are world-first research into the delivery of beneficial soil microbes using drones and the first assessment globally of the cost-effectiveness of drone restoration utilizing data from spatial analysis and extensive field trials. This should provide wide-ranging benefits for local land managers restoring remote degraded land and aid in reversing the cumulative effects of habitat loss on biodiversity. Read moreRead less
Plasticity and the origins of family. This project aims to answer the question of how family life evolved. Humans and many animals live in stable family groups because of the benefits of cooperation. Surprisingly, we have a very poor understanding of how family living initially evolved. This project will experimentally determine how simple responses to environmental change have driven the evolution of family living and thereby refine theories for understanding social evolution more generally. ....Plasticity and the origins of family.

Surprisingly, we have a very poor understanding of how family living initially evolved. This project will experimentally determine how simple responses to environmental change have driven the evolution of family living and thereby refine theories for understanding social evolution more generally. This information will be useful to environmental policy makers that need to consider the role of environmental change in managing and conserving viable populations.Read moreRead less
Reef health tipping-points: triage for threatened/collapsed reef ecosystems. The accelerating collapse of reef ecosystems represents one of the greatest threats for marine biodiversity and seafood production worldwide. To confront this emergency, this Fellowship will determine reef health tipping-points and provide a new 'reef ecosystem triage’ approach to prioritise the order of preventative treatments to safeguard threatened reefs, while directing remediation efforts to collapsed reefs where r ....Reef health tipping-points: triage for threatened/collapsed reef ecosystems. The accelerating collapse of reef ecosystems represents one of the greatest threats for marine biodiversity and seafood production worldwide. To confront this emergency, this Fellowship will determine reef health tipping-points and provide a new 'reef ecosystem triage’ approach to prioritise the order of preventative treatments to safeguard threatened reefs, while directing remediation efforts to collapsed reefs where recovery is most probable. The research will directly benefit reef-dependent industries and coastal communities by providing an objective evidence-based reef health system to protect against collapse and to identify our greatest opportunities to recover vast biodiversity and economic potential for reef ecosystems.Read moreRead less
Global patterns of mammalian biodiversity loss over the last 50,000 years. Wild mammals have experienced major population losses and extinctions in recent centuries, but their communities had already suffered from widespread losses during the Pleistocene. Existing literature has focused on documenting individual extinctions or continental-scale patterns. This project aims to show how biodiversity loss played out at the local scale around the world. It will use palaeontological and zooarchaeologi ....Global patterns of mammalian biodiversity loss over the last 50,000 years. Wild mammals have experienced major population losses and extinctions in recent centuries, but their communities had already suffered from widespread losses during the Pleistocene. Existing literature has focused on documenting individual extinctions or continental-scale patterns. This project aims to show how biodiversity loss played out at the local scale around the world. It will use palaeontological and zooarchaeological data to show how losses varied in space, how population sizes changed, and how species attributes such as rarity and body size related to loss. The world of mammals has become more homogeneous as biodiversity has declined. The challenge is to show how that happened across space and time.

This project aims to reduce the impacts of wind turbines and disturbance from forestry activity on the Tasmanian wedge-tailed eagle. It will do this by understanding the flight behaviour, movements and mortality of eagles, and the behavioural responses of breeding birds to forestry-related disturbance. The project will build new knowledge and institutional partnerships that will be used to minimise impacts on the Tasmanian eagle population, and develop models for use in planning. This will safeguard Australia's largest eagle and improve the sustainability of energy and forest industries. This research will also provide a model for the resolution of similar problems elsewhere in the world.Read moreRead less
