Colour vision in birds: consequences to fatal collisions with wind farms. Wind-farms represent a key component of sustainable energy generation world-wide. However, many birds die as a result of collisions with wind-farms, posing an unsolved and controversial conservation issue. The proliferation of wind-farms in Australia will exacerbate the problem. Birds rely on vision to negotiate static and moving objects. Wind-farms, currently coloured to meet human aesthetic criteria, may be 'invisible' t ....Colour vision in birds: consequences to fatal collisions with wind farms. Wind-farms represent a key component of sustainable energy generation world-wide. However, many birds die as a result of collisions with wind-farms, posing an unsolved and controversial conservation issue. The proliferation of wind-farms in Australia will exacerbate the problem. Birds rely on vision to negotiate static and moving objects. Wind-farms, currently coloured to meet human aesthetic criteria, may be 'invisible' to birds since they see colours differently from humans. We will determine bird spectral sensitivities and compare them to the spectral reflectance of wind-farms. We will then develop modifications improving the visibility of wind-farms to birds, thereby reducing fatalities.Read moreRead less
DNA Method for Detection of Phytophthora cinnamomi in Soil and Plant Material. The need to impose strict quarantine procedures to prevent the spread of Jarrah Dieback disease hampers the activities of the mining, tourism, wildflower, nursery, and bee keeping industries. These procedures are time consuming and require a high degree of technical expertise. They result in false negatives facilitating the spread of the disease in asymptomatic material. This project will develop a DNA test for detec ....DNA Method for Detection of Phytophthora cinnamomi in Soil and Plant Material. The need to impose strict quarantine procedures to prevent the spread of Jarrah Dieback disease hampers the activities of the mining, tourism, wildflower, nursery, and bee keeping industries. These procedures are time consuming and require a high degree of technical expertise. They result in false negatives facilitating the spread of the disease in asymptomatic material. This project will develop a DNA test for detection of the pathogen in soil and plant material to make detection easier, quicker, and specific. The outcomes will be a test for detection of the dieback pathogen and technology to detect pathogens in soil samples.Read moreRead less

Approximately 41% of the 5750 plant species in Western Australia are susceptible to Phytophthora cinnamomi a pathogen recognised as a key threatening process to Australia's biodiversity by the Federal Government. This project will enhance our understanding of how the pathogen survives in soil and tolerant plant species. It will determine how the pathogen is able to survive long-term as dormant propagules and how this dormancy can be broken. This project will be relevant to managers of natural ecosystems and to the horticultural industries throughout Australia and will assist in developing effective ways to manage this ecologically devastating plant pathogen.

Phyloinformatics and biodiversity: developing bioinformatic tools for understanding the dynamics of extinction and invasion within species assemblages. DNA sequence data provides an exciting new way to study biodiversity, because the genome of each organism records its evolutionary history. By analysing DNA sequences co-existing species, we can reconstruct the ecological and evolutionary history of a biological community. This allows us to track biodiversity changes over time, and examine how th ....Phyloinformatics and biodiversity: developing bioinformatic tools for understanding the dynamics of extinction and invasion within species assemblages. DNA sequence data provides an exciting new way to study biodiversity, because the genome of each organism records its evolutionary history. By analysing DNA sequences co-existing species, we can reconstruct the ecological and evolutionary history of a biological community. This allows us to track biodiversity changes over time, and examine how the state of a species assemblage determines which species are lost through extinction or gained through the invasion of exotic species. Understanding the factors that govern changes in biodiversity over time is essential for planning for future conservation in the face of a rapidly changing environment. Read moreRead less

The aims of this work are to test a commercially available long-acting contraceptive on large populations of kangaroos and koalas, and to devise efficient, economic and practical ways of delivering these contraceptives to the animals. The outcome will be a system of controlling the number of these animals which is economically realistic and acceptable to national and international communities. The contraceptive is administered as a small, subcutaneous implant in the back of the neck. It can be inserted very quickly and has no harmful side effects. A further outcome may be its adoption in other parts of the world, to the advantage of the company which manufactures it.Read moreRead less

We will dissect the interaction between an Australian butterfly and changing climate. This will make significant contributions to the national research priorities Responding to climate change and variability and Sustainable use of Australia's biodiversity. We will address the known deficits in standard approaches to predicting futures for biota. We will provide an Australian species in which the mechanisms of response to climate change are understood in detail. Our outputs will be directly applicable to other butterflies: 19 threatened taxa in Australia. The novelty of our approach will be of marked international interest, and will train Australian researchers in a new way of predicting biological impacts of climate change.Read moreRead less
How do ecologically significant complex traits evolve in natural populations? Evolution and selection on plant chemistry in Eucalyptus. The scent of Eucalyptus oil is one of the signatures of Australia but we actually import large amounts of these oils. As well as being valuable industrially, Eucalyptus oils also influence many aspects of our environment ranging from icons such as the koala to the occurrence of smog in cities. Understanding how plants make these oils helps us to understand eco ....How do ecologically significant complex traits evolve in natural populations? Evolution and selection on plant chemistry in Eucalyptus. The scent of Eucalyptus oil is one of the signatures of Australia but we actually import large amounts of these oils. As well as being valuable industrially, Eucalyptus oils also influence many aspects of our environment ranging from icons such as the koala to the occurrence of smog in cities. Understanding how plants make these oils helps us to understand ecological processes and also to improve the financial incentives for land restoration through the planting of valuable oil-bearing trees. We aim to use recent new techniques in genetics to explain why the quantity and types of Eucalyptus oils vary so widely and to apply this information to improving land management and conservation.Read moreRead less

Western Barred Bandicoots are highly endangered marsupials, found in the wild only on Bernier and Dorre islands in Western Australia. Captive breeding and reintroduction efforts, considered essential for survival of this species, are currently hampered by a progressively debilitating, wart-like syndrome and reduced fertility. This project will use pathological, immunohistochemical and ultrastructural techniques in combination with novel molecular methods, and lymphocyte proliferation assays to determine the causes and conservation implications of these conditions. The hypothesis is that these conditions are a consequence of a viral or chlamydial infection in immunocompromised animals.Read moreRead less
