Summary
Family matters: kin selection and competition in cooperative breeders. In the absence of dispersal of one or both sexes kin competition and inbreeding are expected to increase. This project will study group living fairy-wrens, which vary in whether or not one sex disperses. The results will shed new light on how species overcome the negative aspects of this behaviour and inform us about the consequences for populations and habitat management.
The evolution and maintenance of specificity, mutualism and diversity in plant-soil microbe interactions. This research will significantly advance knowledge regarding the evolution of mutualisms between plant and soil microbes. Results will provide valuable data on the importance of below-ground microbial community structure to growth and productivity of an ecologically important component of the Australian flora (Acacia spp.), and contribute to the development of best ecosystem restoration prac ....The evolution and maintenance of specificity, mutualism and diversity in plant-soil microbe interactions. This research will significantly advance knowledge regarding the evolution of mutualisms between plant and soil microbes. Results will provide valuable data on the importance of below-ground microbial community structure to growth and productivity of an ecologically important component of the Australian flora (Acacia spp.), and contribute to the development of best ecosystem restoration practices. Furthermore, it will see the continued development of the Acacia-rhizobia system as a world-class model for exploring interactions between perennial legumes and microbial symbionts. The research also investigates the adaptability and potential for rapid evolution of critical elements of the soil microflora to environmental change.Read moreRead less
Conservation biology of the largest Australian freshwater tortoise, the broad-shelled tortoise, Chelodina expansa - rare and endangered or cryptic and secure? The Murray is a highly managed river, with flows controlled by catchments and diversions. The combined impacts of water resource development, habitat modification and introduced species are astonishingly diverse, and include extinctions of some fish and invertebrates and depression of populations of many other species. Australia's largest ....Conservation biology of the largest Australian freshwater tortoise, the broad-shelled tortoise, Chelodina expansa - rare and endangered or cryptic and secure? The Murray is a highly managed river, with flows controlled by catchments and diversions. The combined impacts of water resource development, habitat modification and introduced species are astonishingly diverse, and include extinctions of some fish and invertebrates and depression of populations of many other species. Australia's largest chelid turtle, the broad-shelled turtle, is a high-level consumer thought to be particularly sensitive to these changes. We will use an innovative combination of non-destructive technologies to investigate the conservation biology of this species in the Lower Murray, where it is regarded as rare and where its biology is virtually unknown to inform conservation management and restoration initiativesRead moreRead less
Can animal dispersal inform fire management for species conservation? This project aims to improve fire management for environmental outcomes in northern Australia. It will address a key knowledge gap in our understanding of the effects of fire on biodiversity, relating to the spatial pattern of fire in the landscape. This is important because changing patterns of fire are not only a risk to humans but have major effects on our environment. This project will involve researchers, environmental ma ....Can animal dispersal inform fire management for species conservation? This project aims to improve fire management for environmental outcomes in northern Australia. It will address a key knowledge gap in our understanding of the effects of fire on biodiversity, relating to the spatial pattern of fire in the landscape. This is important because changing patterns of fire are not only a risk to humans but have major effects on our environment. This project will involve researchers, environmental managers and indigenous land owners to design better fire management strategies for biodiversity. The key benefits include new knowledge and tools to better manage fire and address one of our major environmental challenges, the decline of native wildlife in northern Australia.Read moreRead less
Boxing clever: artificial nest boxes as a conservation and research tool. Saving endangered species increasingly requires proactive management. This project presents an innovative and practical solution to save an iconic Australian species, while also providing the scientific foundation for the development of a novel Australian-based commercial product that will be used to protect and restore Australian biodiversity.
Testing the waters: impacts of contaminants on ecosystem structure and function in urban waterways. To ensure that people can swim, catch fish and enjoy the beauty of urban waterways we need to be able to predict the effects of more than one stressor at a time. This project will determine how nutrients and metals affect our waterways. Findings will help prioritise management actions that protect biodiversity and human uses of these systems.
Understanding snow gum dieback for effective and integrated management. The project leverages recent research and infrastructure investments and our determined and collaborative team as it aims to: 1) assess the future geography of snow gum dieback in the high country and identify priority locations for pro-active management, 2) quantify the impact of snow gums on high country water and carbon budgets and thus the socio- economic and biodiversity values, and 3) determine options for mitigation. ....Understanding snow gum dieback for effective and integrated management.

Dieback of our iconic snow gum forests is diminishing the ecological, hydrological and cultural values of the Australian Alps and will impact state and national water-supply and power-generation systems. Our research will inform Alps-wide management efforts designed for long-term success.Read moreRead less
Novel habitat quality assessment to inform the development of recreational boating infrastructure. As Australians migrate towards the coast, the demand for recreational boating facilities such as moorings and marinas is increasing rapidly. These structures can remove habitat and fragment the seascape in a similar manner to roads and clearings in forest and grasslands. Coastal infrastructure can also reduce the quality of existing habitats and their full impact must be assessed if the diversity a ....Novel habitat quality assessment to inform the development of recreational boating infrastructure. As Australians migrate towards the coast, the demand for recreational boating facilities such as moorings and marinas is increasing rapidly. These structures can remove habitat and fragment the seascape in a similar manner to roads and clearings in forest and grasslands. Coastal infrastructure can also reduce the quality of existing habitats and their full impact must be assessed if the diversity and function of coastal seascapes is to be conserved. This project aims to use a combination of novel modelling, surveys, and large experiments to understand how threatened seagrass, fish, and sediment habitats are altered in human modified seascapes, and to assess the success of habitat restoration following the removal of boating structures.Read moreRead less
New multi-scale seed dispersal models for improved regional weed management. This project will exploit recent advances in ecological and atmospheric modelling with the aim to build improved models of seed dispersal across landscapes to anticipate weed spread. Damaging invasive plants are rapidly transforming landscapes and altering ecosystem function worldwide. The speed and direction of weed spread determines the success or failure of costly containment and control actions, however we lack the ....New multi-scale seed dispersal models for improved regional weed management. This project will exploit recent advances in ecological and atmospheric modelling with the aim to build improved models of seed dispersal across landscapes to anticipate weed spread. Damaging invasive plants are rapidly transforming landscapes and altering ecosystem function worldwide. The speed and direction of weed spread determines the success or failure of costly containment and control actions, however we lack the ability to adequately predict spread. New models that combine micrometeorological measurements, within-canopy turbulence and topographic variation in wind flows will be designed to better predict where dispersal will occur. In this project, these improved predictions are planned to be combined with decision models to direct the management of invasive species across entire landscapes.Read moreRead less
