Ecological and genetic connectivity in seagrasses: the role of sexual reproduction, dispersal and recruitment on meadow restoration. This project's goal is to study the role of dispersal in contemporary demographics and genetics of an Australian seagrass genus Posidonia. The expected outcome of this project is to understand the importance of long-distance dispersal of seeds in determining resilience of seagrasses to both natural and anthropogenic disturbances.
Genetic Rescue of Australia's Arid Zone Plants. Many Australian arid zone plant species have been severely damaged by grazing, loss of pollinators and other impacts and cannot survive without urgent intervention. Some exist as small fragmented populations with too little genetic variation to reproduce or adapt to further environmental change. We propose to combine surveys of genetic (DNA) diversity and the reproductive status of populations in order to identify species that could be saved by a ....Genetic Rescue of Australia's Arid Zone Plants. Many Australian arid zone plant species have been severely damaged by grazing, loss of pollinators and other impacts and cannot survive without urgent intervention. Some exist as small fragmented populations with too little genetic variation to reproduce or adapt to further environmental change. We propose to combine surveys of genetic (DNA) diversity and the reproductive status of populations in order to identify species that could be saved by a process of ‘genetic rescue’. Genetic rescue will involve experimental pollinations to produce highly fit seedlings and later transplanting of these seedlings to augment genetically deficient populations.

Connectivity and movements of large pelagic species of ecotourism value. The project aims to answer key questions about the biology, ecology and sustainability of the world’s manta ray species to provide the information and tools for management and conservation of these charismatic and valuable species. In particular, the project aims to determine the likely impact of climate variability and fisheries that operate to Australia’s north on manta-based ecotourism in the Indo-Pacific region, as clim ....Connectivity and movements of large pelagic species of ecotourism value. The project aims to answer key questions about the biology, ecology and sustainability of the world’s manta ray species to provide the information and tools for management and conservation of these charismatic and valuable species. In particular, the project aims to determine the likely impact of climate variability and fisheries that operate to Australia’s north on manta-based ecotourism in the Indo-Pacific region, as climate change and active low-value fisheries may both jeopardise a high-value ecotourism industry. The project seeks to explore geographic distributions, local and large-scale movements, population sizes, structure, and inter-connectivity in the region to assess the effect of climate and fisheries on manta ray populations.Read moreRead less
Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and sourc ....Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and source of stocked versus wild fish determined in stocked and unstocked rivers. Natural chemical signatures will also help determine important recruitment areas. The outcomes will allow fisheries managers to make informed decisions regarding stocking strategies.Read moreRead less
The impact of severe bushfires on the ecology, demography and genetics of frogs in the Victorian Kinglake region. The February 2009 bushfires in Victoria devastated many communities, and also had a profound impact on wildlife species. This research is aimed at measuring the impact of these fires on frogs in the Kinglake region. It will provide a range of national benefits, including a better understanding of the effects of wildfire on native species and their habitats, information to help plan c ....The impact of severe bushfires on the ecology, demography and genetics of frogs in the Victorian Kinglake region. The February 2009 bushfires in Victoria devastated many communities, and also had a profound impact on wildlife species. This research is aimed at measuring the impact of these fires on frogs in the Kinglake region. It will provide a range of national benefits, including a better understanding of the effects of wildfire on native species and their habitats, information to help plan conservation efforts for frogs, and a vital connection with local landowners; some of whom lost their homes in the fires but were still concerned about the wellbeing of frogs in the area. Australia is a fire-prone country, and this project will help develop responses to the threats posed by the expected increase in the frequency and intensity of fires in southern Australia.Read moreRead less
Australian alpine seed ecology: Plant conservation and adaptation to climate change. The Australian alpine region is critically vulnerable to climate change. Many alpine plant species are already threatened. Our project facilitates effective management of Australian alpine flora, enabling us to preserve alpine biodiversity and improve ecosystem resilience to climate change.

Many alpine plant species are already threatened. Our project facilitates effective management of Australian alpine flora, enabling us to preserve alpine biodiversity and improve ecosystem resilience to climate change. Seed banking provides conservation of nationally vulnerable and threatened flora, providing insurance against extinction. Our exemplary contribution to global seed conservation provides a national resource of alpine seeds for revegetation and research and interpretive resources at the Australian National Botanic Gardens facilitate public awareness of the ecological significance and fragility of Australian alpine ecology in response to climate change.Read moreRead less
Selection and deployment of browsing resistant Eucalyptus globulus and Eucalyptus nitens. Marsupial browsing is a significant problem for eucalypt plantation establishment in Australia. To date, browsing control has relied on the use of 1080 pesticide, but through political and social pressure this will cease in Tasmanian State Forests by December 2005. To develop new approaches to integrated pest management, we will explore the use of natural plant resistance to marsupial browsers. We will dete ....Selection and deployment of browsing resistant Eucalyptus globulus and Eucalyptus nitens. Marsupial browsing is a significant problem for eucalypt plantation establishment in Australia. To date, browsing control has relied on the use of 1080 pesticide, but through political and social pressure this will cease in Tasmanian State Forests by December 2005. To develop new approaches to integrated pest management, we will explore the use of natural plant resistance to marsupial browsers. We will determine the genetic and chemical basis of seedling resistance in Eucalyptus globulus and E. nitens, and investigate the stability of resistance though tree development and across different sites. Resistant germplasm will be identified and tested in operational plantings.Read moreRead less
Overcoming critical recruitment bottlenecks limiting seedling establishment in degraded seagrass ecosystems: a systems approach to restoration. This project will apply a demographic approach, adopted from terrestrial models of seed-based restoration, to identify those early life-stage transitions most limiting to seedling establishment in seagrass restoration.
Working with wind energy and forestry for effective eagle conservation. 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 e ....Working with wind energy and forestry for effective eagle conservation. 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
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
