Testing the importance of large-scale climate factors to plant community assembly following land-use change. This project will examine the native plant species and functional diversity of Australia's rain forest communities to create a predictive framework of how plant communities recover following deforestation. Such a framework is key to focusing conservation efforts in degraded and multi-use landscapes.

Summary
Forecasting ecosystem collapse and recovery by tracking networks of species. This project aims to assess and predict ecosystem decline by measuring change in networks of interacting species. Efforts to prevent ecosystem collapse are failing. A focus on managing individual species ignores the fact that ecosystems function because species have complex associations with one another and the environment. This project will use methods from social networks, food-web theory and web-searching behaviour, ....Forecasting ecosystem collapse and recovery by tracking networks of species. This project aims to assess and predict ecosystem decline by measuring change in networks of interacting species. Efforts to prevent ecosystem collapse are failing. A focus on managing individual species ignores the fact that ecosystems function because species have complex associations with one another and the environment. This project will use methods from social networks, food-web theory and web-searching behaviour, to discover symptoms of declining ecosystems and find robust metrics that diagnose change in networks of co-occurring species. The intended outcome is to clarify the relationship between species interactions, co-occurrence and ecosystem decline, knowledge critical to ecosystem recovery.Read moreRead less
From genes to ecosystems: does genetic divergence in eucalyptus alter biodiversity and ecosystem function? The project will use a dominant tree species of south-eastern Australia to examine how genetic based variation in its traits influences community organisation, biodiversity and ecosystem processes. Outcomes from this research will be important for responding to an uncertain future environment and maintaining the services ecosystems provide.

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
Habitat degradation on coral reefs. This project aims to determine how reef degradation modifies predator-prey dynamics in fish communities, and how parental effects may help species to cope with habitat change. Live corals are ecosystem engineers that support the world’s most biodiverse communities, but anthropogenic factors have led to unprecedented global declines in live coral. The transition from live to dead coral-dominated habitats is associated with a modified sensory landscape of fear f ....Habitat degradation on coral reefs. This project aims to determine how reef degradation modifies predator-prey dynamics in fish communities, and how parental effects may help species to cope with habitat change. Live corals are ecosystem engineers that support the world’s most biodiverse communities, but anthropogenic factors have led to unprecedented global declines in live coral. The transition from live to dead coral-dominated habitats is associated with a modified sensory landscape of fear for resident fishes, via chemical interference emanating from degraded coral. Inter-generational advantages would help management to regulate reef usage to promote resilience.Read moreRead less

Summary
Assessing pollination services of honey bees in native ecosystems and threats posed by parasites. The European honeybee is our most abundant pollinator but we know little about its role in native Australian ecosystems or how its many diseases may affect its ability to pollinate. This project will determine whether honeybees are important pollinators of native plants and how a common parasite affects their pollination ability.
Functional-trait approach to restoration of species-rich shrublands. The project aims to deliver management tools that will help mining companies to meet restoration targets and to improve the field of trait-based predictive restoration ecology. Species-rich kwongan shrublands of south-west Australia are a biodiversity treasure. Despite their global and national conservation value, little is known about which plant traits are most important for community assembly and diversity maintenance. This ....Functional-trait approach to restoration of species-rich shrublands. The project aims to deliver management tools that will help mining companies to meet restoration targets and to improve the field of trait-based predictive restoration ecology. Species-rich kwongan shrublands of south-west Australia are a biodiversity treasure. Despite their global and national conservation value, little is known about which plant traits are most important for community assembly and diversity maintenance. This project plans to use plant functional traits related to nutrient and water acquisition to predict plant community assembly under different soil resource availabilities and thus assist in successful rehabilitation of this native vegetation after closure of sand-mining operations.Read moreRead less
Warming up predator-prey interactions. Predator-prey interactions are the building blocks of communities, but these will change with shifts in distribution due to carbon dioxide (CO2)-induced increases in temperature. Coral reefs are particularly vulnerable and the project will explore how temperature elevation will influence the physiological performance and ecology of fish to alter these fundamental interactions.

Summary
Insect diversity and carrion decomposition in modified landscapes. Decomposition is fundamental to the recycling of nutrients in ecosystems, yet it is not known how different combinations of decomposer insects contribute to this important ecosystem service. This project includes a series of experiments to examine how insects affect carrion decomposition rates, and how this depends on environmental context. The project aims to show how decomposition is maintained in variable and changing landscap ....Insect diversity and carrion decomposition in modified landscapes. Decomposition is fundamental to the recycling of nutrients in ecosystems, yet it is not known how different combinations of decomposer insects contribute to this important ecosystem service. This project includes a series of experiments to examine how insects affect carrion decomposition rates, and how this depends on environmental context. The project aims to show how decomposition is maintained in variable and changing landscapes by revealing when the loss or gain of species will alter this critical ecological process. This will have implications for biodiversity-ecosystem function theory, and applications to biodiversity management and ecosystem restoration.Read moreRead less

Assessing the ecosystem-wide risks of threatened species translocation. This project aims to develop the first quantitative risk assessment framework to improve decisions about moving threatened species to new places. Moving threatened plants and animals to new environments, or reintroducing them where they previously persisted, is a growing focus of conservation. Moving species can have unanticipated effects on other species in the ecosystem. Although the International Union for Conservation of Nature deems ecosystem-wide risk assessments essential for conservation translocations, no framework exists to assess these risks and inform these decisions. New tools for assessing the risks of conservation translocations are expected to improve global and local conservation outcomes.Read moreRead less
