Physiological effects of extreme hot weather on animals’ metabolism, development, body size and cell lifespan. This project aims to determine the physiological effects of extreme hot weather on animals’ metabolism, development, body size and cell lifespan. Body size in animals is negatively related to latitude; individuals are relatively small in hot climates. The project will test the idea that the adverse effects of heat during development constrain body size. The project will draw on physiolo ....Physiological effects of extreme hot weather on animals’ metabolism, development, body size and cell lifespan. This project aims to determine the physiological effects of extreme hot weather on animals’ metabolism, development, body size and cell lifespan. Body size in animals is negatively related to latitude; individuals are relatively small in hot climates. The project will test the idea that the adverse effects of heat during development constrain body size. The project will draw on physiology, endocrinology, behaviour and cell biology and study birds across Australian climates and in a temperature-controlled laboratory. The outcomes of the project will provide insight into regional variation in species vulnerabilities to climate variation and inform biodiversity management.Read moreRead less
Managing urban trees. Managing urban trees. This project aims to explore the effects of different urban tree types and plantings on people and wildlife in Melbourne, Moreland and Ballarat so they can better plan their future urban forests. Local governments spend millions of dollars planting and maintaining urban trees every year. Research provides little guidance to these land managers when making critical decisions in a rapidly changing social and physical environment. This project will combin ....Managing urban trees. Managing urban trees. This project aims to explore the effects of different urban tree types and plantings on people and wildlife in Melbourne, Moreland and Ballarat so they can better plan their future urban forests. Local governments spend millions of dollars planting and maintaining urban trees every year. Research provides little guidance to these land managers when making critical decisions in a rapidly changing social and physical environment. This project will combine tree inventory data with new information on the social and ecological effects of trees (e.g. human well-being, bird diversity). This research is expected to guide future tree management decisions that have better social and environmental outcomes for Australia’s cities.Read moreRead less
Biotic connectivity within the temperate Australian marine protected area network at three levels of biodiversity, communities, populations and genes. Project outcomes will improve management of coastal biodiversity through a multi-state collaboration of managers, marine ecologists, population geneticists and taxonomists. Sites most needed within marine protected area (MPA) networks for maintaining resilience of populations across seascapes will be identified, including sites with exceptional en ....Biotic connectivity within the temperate Australian marine protected area network at three levels of biodiversity, communities, populations and genes. Project outcomes will improve management of coastal biodiversity through a multi-state collaboration of managers, marine ecologists, population geneticists and taxonomists. Sites most needed within marine protected area (MPA) networks for maintaining resilience of populations across seascapes will be identified, including sites with exceptional endemism or key roles in dispersal of larvae. The ecological efficacy of the temperate Australian MPA network will be assessed through analysis of long-term ecological datasets and further development of a novel 'remote sensing' methodology, whereby surveys are undertaken by volunteer divers across much greater spatial and temporal scales than could be studied by dedicated scientific dive teams.Read moreRead less
Resolving human-flying fox conflict in the face of environmental change. Resolving human-flying fox conflict in the face of environmental change. This project aims to identify socially-acceptable priority areas to be managed for the long-term viability of flying-foxes under a changing climate, and develop strategies to mitigate human-flying fox conflict, using ecological and social analysis in a decision-theoretic framework.

Resolving human-flying fox conflict in the face of environmental change. This project aims to identify socially-acceptable priority areas to be managed for the long-term viability of flying-foxes under a changing climate, and develop strategies to mitigate human-flying fox conflict, using ecological and social analysis in a decision-theoretic framework. Flying-foxes are nationally protected mammals pivotal to Australia’s forest ecosystems, but are threatened by habitat loss, extreme weather and legal culls at orchards. Their exceptional mobility puts them in frequent conflict with human settlements, leading to forced dispersals from roosts. Anticipated outcomes are the conservation of Australia’s flying-foxes and international understanding of how to resolve human conflict with highly mobile species that are threatened but locally abundant and controversial.Read moreRead less
Developing Assisted Reproductive Technologies for the Conservation of Critically Endangered Australian Amphibians. Unprecedented rates of species extinction are of global concern. Although high extinction rates are reported for all vertebrate classes, amphibians are the most severely affected. Captive-breeding programs play a key role in maintaining populations of endangered amphibian species, but in most cases reproductive rates are too low to support long term re-introduction programmes. This ....Developing Assisted Reproductive Technologies for the Conservation of Critically Endangered Australian Amphibians. Unprecedented rates of species extinction are of global concern. Although high extinction rates are reported for all vertebrate classes, amphibians are the most severely affected. Captive-breeding programs play a key role in maintaining populations of endangered amphibian species, but in most cases reproductive rates are too low to support long term re-introduction programmes. This study aims to develop sophisticated Assisted Reproductive Technologies (ART) to enhance the propagation and genetic management of endangered Australian frog species. ART is a powerful new approach to ex situ conservation that, if integrated into existing captive breeding programs, will ensure the preservation of Australia’s unique amphibian biodiversity.Read moreRead less

Understanding plant:fungal communication to increase plant productivity. Relationships between mutualistic fungi and plants are exploited as they foster plant productivity and vigour. One significant problem facing the agro-forestry and agricultural industries is that the ability of beneficial fungi to colonise plant hosts is highly dependent on the genetic background of the host. Ultimately, this means that if fungal inoculants are not matched with the appropriate plant host, maximal benefits f ....Understanding plant:fungal communication to increase plant productivity. Relationships between mutualistic fungi and plants are exploited as they foster plant productivity and vigour. One significant problem facing the agro-forestry and agricultural industries is that the ability of beneficial fungi to colonise plant hosts is highly dependent on the genetic background of the host. Ultimately, this means that if fungal inoculants are not matched with the appropriate plant host, maximal benefits from these relationships are not achieved. This project aims to identify the first genetic markers to be used for matching plants with appropriate fungal isolates, thereby guaranteeing optimal plant performance. This will add a critical component to the global effort of increasing the productivity of our natural resources.Read moreRead less
Factors controlling ectomycorrhizal contributions to plant N nutrition. This project aims to define the mechanistic link between nitrogen metabolism in symbiotic ectomycorrhizal fungi and its effect on the quantity of nitrogen shared with a plant host. Using a genetically diverse population of a key Australian fungal species, the project expects to uncover genetic features related to nitrogen metabolism that correlate to improved support of plant nutrition. Expected outcomes include better under ....Factors controlling ectomycorrhizal contributions to plant N nutrition. This project aims to define the mechanistic link between nitrogen metabolism in symbiotic ectomycorrhizal fungi and its effect on the quantity of nitrogen shared with a plant host. Using a genetically diverse population of a key Australian fungal species, the project expects to uncover genetic features related to nitrogen metabolism that correlate to improved support of plant nutrition. Expected outcomes include better understanding of plant-microbe interactions, groundwork for tools to better model the role of fungi in soil nutrient cycling and guidelines for plant:fungal pairings in reforestation practices. Overall, these should provide significant benefit to the global effort in understanding the role of soil microbes in plant nutrition.Read moreRead less
Characterising controls of carbon flow from trees into mycorrhizal fungi. This project aims to improve our understanding of below-ground carbon sequestration. A significant portion of plant photosynthate is shuttled to root-associated mutualistic ectomycorrhizal fungi in forest ecosystems. Therefore, fungal partners of forest trees are valuable carbon sinks. One problem impeding below-ground carbon accounting in forest soils is a lack of understanding concerning the genetic control of how photos ....Characterising controls of carbon flow from trees into mycorrhizal fungi. This project aims to improve our understanding of below-ground carbon sequestration. A significant portion of plant photosynthate is shuttled to root-associated mutualistic ectomycorrhizal fungi in forest ecosystems. Therefore, fungal partners of forest trees are valuable carbon sinks. One problem impeding below-ground carbon accounting in forest soils is a lack of understanding concerning the genetic control of how photosynthetically fixed sugars are passed to root-associated microbes. This project aims to identify and characterise the sugar transporters that shuttle carbon in ectomycorrhizal plant–fungal interactions and investigate how these are affected by elevated carbon dioxide. It may also identify isolates of mutualistic fungi that could be paired with eucalypt hosts to maximise carbon sequestration and forest productivity.Read moreRead less

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
