Oral Delivery - A Viable Strategy for Fertility Control Vaccination of Kangaroos ? Local overabundance of kangaroos poses significant, environmental, economic, social and animal welfare problems in Australia. The only management tool available for free ranging populations is shooting. Fertility control is a highly desirable alternative but current 'hands on' methods are not cost-effective options for wild populations. Immunologically-mediated contraception has the potential to be such a manag ....Oral Delivery - A Viable Strategy for Fertility Control Vaccination of Kangaroos ? Local overabundance of kangaroos poses significant, environmental, economic, social and animal welfare problems in Australia. The only management tool available for free ranging populations is shooting. Fertility control is a highly desirable alternative but current 'hands on' methods are not cost-effective options for wild populations. Immunologically-mediated contraception has the potential to be such a management tool if the vaccine can be delivered effectively. The investigators and their colleagues have achieved contraception by vaccine injection in kangaroos. This project aims to establish proof-of-concept for arguably the only viable vaccine delivery option for free ranging macropods: Oral delivery via an edible pellet or lick.Read moreRead less
Grazing as a management tool for biodiversity conservation: adaptive management strategies for threatened grassland ecosystems. Lowland temperate grasslands are threatened Australian ecosystems that support an important, and in many cases threatened, biota. These habitats are significantly under-represented in the reserve system, and occur in bioregions that have been subjected to extensive vegetation clearing, intensive production and high stocking densities. This project will develop strategie ....Grazing as a management tool for biodiversity conservation: adaptive management strategies for threatened grassland ecosystems. Lowland temperate grasslands are threatened Australian ecosystems that support an important, and in many cases threatened, biota. These habitats are significantly under-represented in the reserve system, and occur in bioregions that have been subjected to extensive vegetation clearing, intensive production and high stocking densities. This project will develop strategies for maintenance of species and habitat diversity in grasslands through the application of adaptive management principles informed by rigorous ecological research. Outcomes include best-practice approaches to on- and off-reserve management in grazed ecosystems, and better approaches to the interaction between research and biodiversity conservationRead moreRead less
Hotspots of endemism for invertebrate conservation in south-east Australia. The project aims to identify and predict hotspots of species endemism to guide conservation and restoration efforts. This work is significant in the current extinction crisis because endemic species (those unique to a region) are at higher risk of extinction due to human causes. The project will model the relationship of narrow range endemic species with contemporary and past environments, estimate the historical loss of ....Hotspots of endemism for invertebrate conservation in south-east Australia. The project aims to identify and predict hotspots of species endemism to guide conservation and restoration efforts. This work is significant in the current extinction crisis because endemic species (those unique to a region) are at higher risk of extinction due to human causes. The project will model the relationship of narrow range endemic species with contemporary and past environments, estimate the historical loss of species through land-clearing and fire, and predict future responses to climate change, to inform conservation planning. Lastly, it will test the efficacy of habitat transplants in restoring local invertebrate assemblages. Benefits include better informed conservation planning and new restoration approaches.Read moreRead less

This project will provide fundamental information on the factors, which influence possum movements and behaviour in urban environments and the effectiveness of current possum relocation strategies. The project is of significance to Zoological Parks as possums at present cause extensive damage to vegetation and pose a threat to animals in the collection through possible transmission of disease. This project will lead to the development and trial of new methods for management of these populations.Read moreRead less
Plastic pollution: new driver altering responses to variable environments. This project aims to determine how bisphenol A (BPA), which now represents a novel environmental driver, alters physiological responses of animals, and how it interacts with other environmental variables to alter ecological and evolutionary trajectories. Plastic pollution is a monumental global environmental and health problem, and Australia has one of the world’s highest exposures to BPA, a plastics leachate. This projec ....Plastic pollution: new driver altering responses to variable environments. This project aims to determine how bisphenol A (BPA), which now represents a novel environmental driver, alters physiological responses of animals, and how it interacts with other environmental variables to alter ecological and evolutionary trajectories. Plastic pollution is a monumental global environmental and health problem, and Australia has one of the world’s highest exposures to BPA, a plastics leachate. This project will use a new zebrafish gene knock-out model to show whether the effects of BPA are transferred between generations, and will establish an international collaboration, thereby increasing Australia's research capacity. Outcomes from the project are expected to benefit environmental management.Read moreRead less
Identifying and managing the ecological impacts of free-ranging wild horses. Wild horses cause significant ecological damage in conservation areas in Australia, but experimental research examining horse impacts is lacking. Our approach is to assess ecological impacts of wild horses in Guy Fawkes River National Park, a significant wilderness in northern NSW. We will describe the relationship between horse abundance and environmental impacts, experimentally determine how horse exclusion affects ....Identifying and managing the ecological impacts of free-ranging wild horses. Wild horses cause significant ecological damage in conservation areas in Australia, but experimental research examining horse impacts is lacking. Our approach is to assess ecological impacts of wild horses in Guy Fawkes River National Park, a significant wilderness in northern NSW. We will describe the relationship between horse abundance and environmental impacts, experimentally determine how horse exclusion affects key environmental variables, and test the sensitivity of threatened plants to wild horse browsing and trampling. A key outcome will be development of scientifically-validated protocols for assessing horse impacts, and for managing wild horses in other areas of eastern Australia.Read moreRead less
Are kangaroos jeopardizing conservation outcomes? There is concern that grazing by over-abundant kangaroos is jeopardising the goals of arid conservation reserves, but there is little evidence about the extent of their impacts. The goal of this proposal is to quantify kangaroos' grazing effects on biodiversity within arid conservation reserves. The results will provide a whole ecosystem understanding of how overgrazing by kangaroos influences the biodiversity conservation value of the vast lands ....Are kangaroos jeopardizing conservation outcomes? There is concern that grazing by over-abundant kangaroos is jeopardising the goals of arid conservation reserves, but there is little evidence about the extent of their impacts. The goal of this proposal is to quantify kangaroos' grazing effects on biodiversity within arid conservation reserves. The results will provide a whole ecosystem understanding of how overgrazing by kangaroos influences the biodiversity conservation value of the vast landscapes of arid Australia. Managers of many conservation reserves, including our project partners, and policy-makers need the information that our experiments will provide to inform the development of strategies to optimise biodiversity conservation and manage the impacts of kangaroos.Read moreRead less
Dynamic networks in a patchy landscape: will species interactions adjust to increased climatic extremes? This project addresses pressing questions on how increased climatic extremes will affect species diversity in arid Australia, building on the longest ecological dataset available for the continent's vast but fragile inland landscapes. Our tests of key ideas about strong interactions among species, their role in building resilient communities and conserving biodiversity, will generate consider ....Dynamic networks in a patchy landscape: will species interactions adjust to increased climatic extremes? This project addresses pressing questions on how increased climatic extremes will affect species diversity in arid Australia, building on the longest ecological dataset available for the continent's vast but fragile inland landscapes. Our tests of key ideas about strong interactions among species, their role in building resilient communities and conserving biodiversity, will generate considerable international interest, while our focus on interactions of species at water sources will address knowledge gaps to inform best practice in managing converted pastoral lands. The results will contribute to retaining healthy functioning ecosystems, and the vital production systems they support, as the global climate changes.Read moreRead less

New-Generation Near Infrared Spectrometer for Ecological Research. Sustainable use of the natural resources of Australia depends on studies that define how ecological communities respond to disturbance and change. An important part of this is understanding how the composition of plants and animals such as insects, change reflecting for example, increased concentrations of toxins.

Sustainable use of the natural resources of Australia depends on studies that define how ecological communities respond to disturbance and change. An important part of this is understanding how the composition of plants and animals such as insects, change reflecting for example, increased concentrations of toxins. However making large numbers of analyses is expensive and slow. Near infrared spectroscopy is a non-destructive analytical method that allows the composition of materials to be deduced based on their interaction with light. Adopting these methods in ecology will allow many samples to be analysed quickly and cheaply and also stop waste and duplication of analytical work.Read moreRead less
