Ecosystem Assembly in Old Fields in the Western Australian Wheatbelt. This project aims to examine the process of ecosystem re-assembly on land which is taken out of agricultural production and left without further management. Land abandonment is common in many parts of the world and could increase dramatically in Australia due to land degradation, salinity and structural change. We will investigate the factors which influence whether native plant species can recolonise abandoned farmland, usin ....Ecosystem Assembly in Old Fields in the Western Australian Wheatbelt. This project aims to examine the process of ecosystem re-assembly on land which is taken out of agricultural production and left without further management. Land abandonment is common in many parts of the world and could increase dramatically in Australia due to land degradation, salinity and structural change. We will investigate the factors which influence whether native plant species can recolonise abandoned farmland, using field and greenhouse studies. We will do this within the context of ecosystem assembly, thereby answering a practical question and also providing input to a conceptual area which is currently of great interest inRead moreRead less
A physiological and biochemical basis for seed storage for biodiversity conservation and restoration. Seed banking is a vital component of the integrated strategies required to conserve biodiversity and restore degraded landscapes. The effectiveness of seed banking for Australian flora is limited by a lack of research into the factors affecting seed viability during storage.

Seed banking is a vital component of the integrated strategies required to conserve biodiversity and restore degraded landscapes. The effectiveness of seed banking for Australian flora is limited by a lack of research into the factors affecting seed viability during storage. For key indicative Australian species this study will focus on morphological, biophysical and biochemical factors governing seed longevity to determine the optimum storage conditions and identify bio-indicators of seed deterioration for rapid determination of seed storage behaviour. This project will develop benchmark standards by which the estimated 325 seed banks storing native seeds in Australia will benefit.Read moreRead less
Establishment of the Australian Cane Toad Genome Program. The Cane Toad is one of Australia's greatest environmental menaces, and is in the top 100 of the "World's Worst invader species". Over a billion toads infest Northern Australia, and they will soon invade WA and move further into NSW. Their poisons and voracious appetite could make many native mammals, birds and reptiles extinct. The only possibility to eradicate the Toad is by biological control, but there is no known control agent. We wi ....Establishment of the Australian Cane Toad Genome Program. The Cane Toad is one of Australia's greatest environmental menaces, and is in the top 100 of the "World's Worst invader species". Over a billion toads infest Northern Australia, and they will soon invade WA and move further into NSW. Their poisons and voracious appetite could make many native mammals, birds and reptiles extinct. The only possibility to eradicate the Toad is by biological control, but there is no known control agent. We will identify the 'Toad's Achilles' heel' against which control agents can be developed. We can do this by identifying every Toad gene. This project forms the first step to this goal by establishing the Australian Cane Toad Genome Program. Toad control will help preserve Australia's unique natural heritage.Read moreRead less
Population Genetics of Fungal Pathogens that Threaten the Biosecurity of Australia's Eucalypts. Many new pathogens and diseases are emerging on exotic eucalypt plantations throughout the world. These emerging diseases pose a threat to native eucalypt forests and plantations in Australia. Vigilant quarantine measures are necessary to prevent the introduction of potentially devastating pathogens into Australia. However, incursions do occur and there is a great need to study these pathogens now, ....Population Genetics of Fungal Pathogens that Threaten the Biosecurity of Australia's Eucalypts. Many new pathogens and diseases are emerging on exotic eucalypt plantations throughout the world. These emerging diseases pose a threat to native eucalypt forests and plantations in Australia. Vigilant quarantine measures are necessary to prevent the introduction of potentially devastating pathogens into Australia. However, incursions do occur and there is a great need to study these pathogens now, before they enter Australia. By studying the population genetics of pathogens, their evolutionary potential can be estimated and with that the extent of the risk they pose to native and planted eucalypts in Australia can be determined.Read moreRead less
An inventory of past biodiversity in Western Australia using ancient DNA. Fossil bones and museum skins are genetic time capsules that facilitate the exploration of Australia's past biodiversity. Travelling back in 'genetic time' provides important insights into how ecosystems functioned prior to the arrival of Europeans and the feral species that accompanied them. This funding will facilitate research into the genetic heritage of endangered WA species such as Woylies and Cockatoos. Native speci ....An inventory of past biodiversity in Western Australia using ancient DNA. Fossil bones and museum skins are genetic time capsules that facilitate the exploration of Australia's past biodiversity. Travelling back in 'genetic time' provides important insights into how ecosystems functioned prior to the arrival of Europeans and the feral species that accompanied them. This funding will facilitate research into the genetic heritage of endangered WA species such as Woylies and Cockatoos. Native species face increasing pressures from climate change and invasive species. Compiling a genetic inventory of WA's past biodiversity will assist in developing scientifically sound conservation management responses. Such approaches are critically important if this biodiversity hotspot is to be preserved for future generations.Read moreRead less
Fungal pathogens threatening the sub-tropical eucalypt plantation industry in Australia. Eucalypt plantations in Australia are at risk from both native pathogens and those that have emerged on exotic eucalypt plantations and been introduced to Australia. Most of the serious pathogens of exotic plantations have emerged in the sub-tropics in climates very similar to those in Queensland. It is not known if these pathogens have already been introduced to Australia; however, increased movement of ger ....Fungal pathogens threatening the sub-tropical eucalypt plantation industry in Australia. Eucalypt plantations in Australia are at risk from both native pathogens and those that have emerged on exotic eucalypt plantations and been introduced to Australia. Most of the serious pathogens of exotic plantations have emerged in the sub-tropics in climates very similar to those in Queensland. It is not known if these pathogens have already been introduced to Australia; however, increased movement of germplasm and forest products increases the risk of introducing new eucalypt pathogens. This project will involve a detailed examination of pathogens present on eucalypts in Queensland. Studies of the diversity of pathogens and determination of their reproductive mode and their pathogenicity will enable for detailed risk assessments. Assessment of genetic trials for disease incidence will provide valuable information for future selections and breeding.Read moreRead less

Discovery of the identity of the component in smoke (a butenolide) that promotes seed germination provides the research platform to deliver smoke-like efficacy for germination of native species used in horticulture, land restoration and biodiversity conservation. The study will investigate five key areas to deliver the national benefits of our discovery: investigate efficacy of butenolide in seed germination; resolve mechanisms of dormancy release via butenolide; optimise synthesis pathways for production of butenolide and germination-effective analogues; investigate the ecologiocal context and natural abundance of butenolide; resolve synthesis and delivery systems for horticulture and restoration.Read moreRead less
Conservation of the threatened western ringtail possum, Pseudocheirus occidentalis: Is translocation a solution? The western ringtail possum, Pseudocheirus occidentalis, is recognised both nationally and internationally as a threatened species.

The western ringtail possum, Pseudocheirus occidentalis, is recognised both nationally and internationally as a threatened species. Control of introduced predators, specifically the fox and feral cat, has been central to the success of threatened fauna conservation in Western Australia. However, it is now critical to demonstrate that translocation can result in sustained fauna recovery. This program aims to determine whether translocating displaced possums to protected habitat is a viable conservation management strategy. The project will assess the importance of introduced predator control, predator interactions, competition with the common brushtail possum and disease on the survival of translocated western ringtail possums.Read moreRead less
Is reintroduction of soil foraging animals critical for the restoration of degraded semi-arid woodlands? Locally-extinct animals are important, not only for their intrinsic value, but because they are thought to be essential for maintaining and restoring healthy ecosystems. This project will give us valuable insights into how ecosystems may have functioned prior to the loss of native animals, and how ecosystems can be restored when the animals are reintroduced. Our research will provide Australi ....Is reintroduction of soil foraging animals critical for the restoration of degraded semi-arid woodlands? Locally-extinct animals are important, not only for their intrinsic value, but because they are thought to be essential for maintaining and restoring healthy ecosystems. This project will give us valuable insights into how ecosystems may have functioned prior to the loss of native animals, and how ecosystems can be restored when the animals are reintroduced. Our research will provide Australian Wildlife Conservancy with the knowledge they need to continue their reintroductions, and information that encourages land managers to adopt strategies to ensure the survival of reintroduced animals outside of formal reserves.

The roles of invasive ants in urban ecosystem dynamics and restoration. The potential impacts of invasive ants are recognised worldwide, and we know that invasive ant species are already present in heavily disturbed areas in southern Australia, particularly in urban settlements. However, as yet, we have very little information on the actual and potential impacts of invasive ants on ecosystem processes. Urban bushland is seen as an important conservation and amenity resource, and there are incre ....The roles of invasive ants in urban ecosystem dynamics and restoration. The potential impacts of invasive ants are recognised worldwide, and we know that invasive ant species are already present in heavily disturbed areas in southern Australia, particularly in urban settlements. However, as yet, we have very little information on the actual and potential impacts of invasive ants on ecosystem processes. Urban bushland is seen as an important conservation and amenity resource, and there are increasing efforts to manage and restore these areas. This project aims to elucidate the likely impact of invasive ants on the maintenance and restoration of urban bushland, and hence provide guidance as to whether management and restoration needs to include invasive ant control.
