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.
Ecosystem quality and herbivore dynamics in tropical rainforests fragmented by deforestation. After logging, large expanses of south-east Asian rainforests are being converted to oil palm plantations. This is occurring within a mega-diverse area of global ecological and conservation significance yet the ecological consequences of this process are poorly understood. This project will examine patterns of changes in key arthropod herbivores, their food resources and natural enemies within experimen ....Ecosystem quality and herbivore dynamics in tropical rainforests fragmented by deforestation. After logging, large expanses of south-east Asian rainforests are being converted to oil palm plantations. This is occurring within a mega-diverse area of global ecological and conservation significance yet the ecological consequences of this process are poorly understood. This project will examine patterns of changes in key arthropod herbivores, their food resources and natural enemies within experimentally fragmented post-logging forests. The project will quantify the effects of fragment size, location and vegetation upon the herbivore dynamics, their impact on the vegetation and their interactions with their natural enemies. The project aid understanding the dynamics of the ecosystems involved and the services they provide.Read moreRead less
Closing the carbon cycle: an ecological understanding of wood decay. The project aims to understand the controls on the return of carbon to the atmosphere within forests, especially focusing on this problem from a microbial perspective. Microbial dynamics and wood decay are crucially important for the global carbon cycle. What the field is lacking is a trait-based ecology of wood decomposers. The project plans to examine the interactions among fungal and oomycete endophytes and decomposers throu ....Closing the carbon cycle: an ecological understanding of wood decay. The project aims to understand the controls on the return of carbon to the atmosphere within forests, especially focusing on this problem from a microbial perspective. Microbial dynamics and wood decay are crucially important for the global carbon cycle. What the field is lacking is a trait-based ecology of wood decomposers. The project plans to examine the interactions among fungal and oomycete endophytes and decomposers through a series of experiments. The expected outcome of this project is a clear understanding of the role of traits in wood decomposer communities, especially their influence on priority effects, competitive hierarchies, and the resultant wood decay rate.Read moreRead less
Fauna, fuel and fire: effects of animals on bushfire risk. This project aims to determine the extent that animals influence fire regimes through effects on fuel load and characteristics. Minimising the risk of large, severe bushfires, while conserving native species is one of the greatest challenges facing managers of fire-prone ecosystems globally. Using a powerful combination of landscape-scale field observations, experimental manipulations of animal densities, and modelling, the project expec ....Fauna, fuel and fire: effects of animals on bushfire risk. This project aims to determine the extent that animals influence fire regimes through effects on fuel load and characteristics. Minimising the risk of large, severe bushfires, while conserving native species is one of the greatest challenges facing managers of fire-prone ecosystems globally. Using a powerful combination of landscape-scale field observations, experimental manipulations of animal densities, and modelling, the project expects to quantify interactions between animals, bushfire fuel and fire regimes in south eastern Australian forests, woodlands and scrublands. This evidence should benefit the design of integrated, efficient, and complementary strategies for fire and fauna management in Australia’s extensive fire-prone ecosystems.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.
Overcoming multiple constraints to wetland forest restoration. This project aims to determine the efficacy of different approaches for restoring wetland forests at the landscape scale. The death and decline of Victoria’s wetland forests, crucial habitat for the endangered helmeted honeyeater and Leadbeater's possum, most likely result from modified flooding patterns, low native tree and shrub recruitment and increased competition from understorey plants. The project intends to reinstate a more n ....Overcoming multiple constraints to wetland forest restoration. This project aims to determine the efficacy of different approaches for restoring wetland forests at the landscape scale. The death and decline of Victoria’s wetland forests, crucial habitat for the endangered helmeted honeyeater and Leadbeater's possum, most likely result from modified flooding patterns, low native tree and shrub recruitment and increased competition from understorey plants. The project intends to reinstate a more natural flood regime, planting native species and reducing competition from dense understorey vegetation. In this way, the project aims to test and advance ecological theory, guide wetland restoration and inform management plans for saving Victoria’s iconic fauna.Read moreRead less

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
Arresting declines of arboreal mammals in the tropical savannas. This project aims to evaluate the hypothesis that arboreal species are limited by the abundance of tree hollows, and that historical increases in the frequency of intense fires may be reducing hollow abundance. Northern Australia’s mammals are in severe decline, and arboreal species are among those that have fared worst. There is abundant anecdotal evidence that a decline in hollow abundance is the cause. Working with the Western A ....Arresting declines of arboreal mammals in the tropical savannas. This project aims to evaluate the hypothesis that arboreal species are limited by the abundance of tree hollows, and that historical increases in the frequency of intense fires may be reducing hollow abundance. Northern Australia’s mammals are in severe decline, and arboreal species are among those that have fared worst. There is abundant anecdotal evidence that a decline in hollow abundance is the cause. Working with the Western Australian Department of Parks and Wildlife in the Kimberley, the last region on the Australian mainland with an intact mammal fauna, the project aims to explore management options for increasing the availability of hollow denning sites for arboreal mammals (e.g. fire management, artificial nest boxes), and evaluate the likely impact of such actions on mammal populations across northern Australia.Read moreRead less
Exotic and native plant coexistence in novel communities. The development of novel communities has become an inevitable outcome of global change. Despite this, we have a poor understanding of the mechanisms driving their assembly. Here, experimental and modelling approaches will be used to identify how competition among native and exotic plant species change across key environmental gradients, leading to: resilient native communities; stable novel communities - mixes of native and exotic species ....Exotic and native plant coexistence in novel communities. The development of novel communities has become an inevitable outcome of global change. Despite this, we have a poor understanding of the mechanisms driving their assembly. Here, experimental and modelling approaches will be used to identify how competition among native and exotic plant species change across key environmental gradients, leading to: resilient native communities; stable novel communities - mixes of native and exotic species; or, degraded communities dominated by exotic species. The annual plant communities of Western Australia's (WA) York Gum woodlands will be used as a model system. Outcomes will improve management of WA wildflower communities and provide a framework for predicting novel community formation worldwide.Read moreRead less
