Maintenance of Australia's forest biodiversity and healthy forested ecosystems are of national importance. Mammal species that are key to dispersing beneficial fungi in our forests have suffered greatest declines in the past, and further declines may ultimately lead to ecosystem collapse. My research seeks to unravel community relationship between mammals and fungi, and how interactions within and between these groups maintain diverse communities. My results will enable forest managers to protect forest biodiversity from current and future threats and to restore degraded ecosystems. Through training of early career ecologists, the research also represents a tangible benefit to Australian science.Read moreRead less
Watching migrating whales: ensuring the sustainability of a growing whale-watch industry. Whale-watching is a huge growth industry, contributing $270 million to Australia in 2003. Yet most whalewatching targets species listed under the EPBC Act 1999 as species slowly recovering from massive overexploitation. Current protection measures are historical (ie best-guess) rather than scientific in origin. We will assess the scientific basis for these protection measures by experimentally manipulating ....Watching migrating whales: ensuring the sustainability of a growing whale-watch industry. Whale-watching is a huge growth industry, contributing $270 million to Australia in 2003. Yet most whalewatching targets species listed under the EPBC Act 1999 as species slowly recovering from massive overexploitation. Current protection measures are historical (ie best-guess) rather than scientific in origin. We will assess the scientific basis for these protection measures by experimentally manipulating tour boat behaviour, and by determining the economic feasibility of the industry. By doing so we will increase the long-term sustainability of the industry, a valuable tourist industry for regional Australia.Read moreRead less
Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia ....Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia from invasive diseases. There is an urgency to undertake our research because global environmental change and increasing movements of people (particularly military personnel) from overseas regions where these diseases are endemic is increasing the vulnerability of northern Australia to the (re)establishment of mosquito borne diseases.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

Summary
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. However making large numbers of analyses is expensive and slow. Near infrared spectroscopy is a non-destructive an ....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. 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
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

This project provides crucial knowledge to achieve an Environmentally Sustainable Australia (National Research Priority) and meets a principal aim of the National Strategy for Ecologically Sustainable Development-to develop sustainable agriculture while protecting the biological resources on which they depend. We achieve this through a novel approach linking production targets and conservation trade-offs with agricultural landscape design and management. This information will underpin the development of policies to improve the environmental performance of Australian agriculture, ensure farming enterprises maximise benefits obtained from native ecosystems, and guarantee profitable and viable rural industries.Read moreRead less

How do foraging herbivores negotiate the twin perils of plant toxins and predators? Our research uses a new framework which links the costs of both plant toxins and predation risk to determine their effects on individual foraging herbivores. This will enable a new way of analysing and predicting the impact of changes to habitat diversity on native herbivores, and the impact of invasive alien herbivore and predator species on natural ecosystems and in human crop production. This is extremely valu ....How do foraging herbivores negotiate the twin perils of plant toxins and predators? Our research uses a new framework which links the costs of both plant toxins and predation risk to determine their effects on individual foraging herbivores. This will enable a new way of analysing and predicting the impact of changes to habitat diversity on native herbivores, and the impact of invasive alien herbivore and predator species on natural ecosystems and in human crop production. This is extremely valuable in today's economic and social climate, when management must be underpinned by evidence of impact and by quantification of costs and benefits of mitigation.Read moreRead less
