Vocal mimicry in songbirds. Many of the world’s largest clade of birds - the songbirds - incorporate vocal mimicry in their songs, but while scientific interest in vocal mimicry dates from Aristotle, limited progress has been made. With our unique research program we aim to provide an empirically based, theoretically informed understanding of avian vocal mimicry. In an important advance, we will examine both sexes to test long-held male-centric assumptions about evolutionary origins and maintena ....Vocal mimicry in songbirds. Many of the world’s largest clade of birds - the songbirds - incorporate vocal mimicry in their songs, but while scientific interest in vocal mimicry dates from Aristotle, limited progress has been made. With our unique research program we aim to provide an empirically based, theoretically informed understanding of avian vocal mimicry. In an important advance, we will examine both sexes to test long-held male-centric assumptions about evolutionary origins and maintenance of this trait. Crucially, we focus on lineages found only in Australia and PNG, where songbirds originated, to develop a robust scientific understanding of vocal mimicry across the entire songbird clade, and so provide an important new perspective on why and how song began.Read moreRead less
Dynamic assessment of threats to marine megafauna in face of global change. This project aims to develop a global approach to synthesise global tracking datasets and deliver near real-time diagnostics on risks for marine megafauna at a global scale pushing forward a new frontier in dynamic marine spatial management to improve conservation.

This project aims to develop a global approach to synthesise global tracking datasets and deliver near real-time diagnostics on risks for marine megafauna at a global scale pushing forward a new frontier in dynamic marine spatial management to improve conservation. This project expects to increase our understanding of how marine megafauna movements vary with environmental changes and how much they overlap with threatening global human activities. Expected outcomes will demonstrate how big data in marine telemetry can be synthesised and translated into ecologically significant behaviours. This should provide significant benefits to address global scientific and societal problems highlighted in the Australian science and research priorities.Read moreRead less
Temperature-dependent toxicity of plant secondary compounds to mammalian herbivores. Changes in the toxicity of plant secondary compounds is an unexplored consequence of rises in ambient temperatures. Evidence from agricultural and laboratory studies suggests that temperature dependent toxicity can have major effects on the intake and metabolism of plant secondary metabolites by mammals. These effects are mediated by a decrease in liver metabolism and by the effects of plant secondary metabolite ....Temperature-dependent toxicity of plant secondary compounds to mammalian herbivores. Changes in the toxicity of plant secondary compounds is an unexplored consequence of rises in ambient temperatures. Evidence from agricultural and laboratory studies suggests that temperature dependent toxicity can have major effects on the intake and metabolism of plant secondary metabolites by mammals. These effects are mediated by a decrease in liver metabolism and by the effects of plant secondary metabolites on mitochondrial function which leads to greater heat production. The project will quantify the importance of temperature dependent toxicity and measures the changes in the cost of detoxification to better model the effects of climate change on marsupial herbivores.Read moreRead less

High throughput nitrogen analysis for ecological studies. Australian environments are unproductive partly because they contain little Nitrogen (N) and changes in atmospheric CO2 will exacerbate this. Furthermore, animals cannot extract all the N from the plants they eat. An assay has been developed that measures how much they can extract (available N) and it is intended to use it to measure habitat quality and the effects of climate change over large tracts of land. This requires thousands of ....High throughput nitrogen analysis for ecological studies. Australian environments are unproductive partly because they contain little Nitrogen (N) and changes in atmospheric CO2 will exacerbate this. Furthermore, animals cannot extract all the N from the plants they eat. An assay has been developed that measures how much they can extract (available N) and it is intended to use it to measure habitat quality and the effects of climate change over large tracts of land. This requires thousands of N analyses. The equipment we are requesting - a LECO combustion analyser, allows us to analyse samples quickly and safely and uses fewer chemicals and much less water than do traditional machines.Read moreRead less
Transgenerational Consequences of Different Environmental Experiences. The project aims to deliver an integrative overview of behavioural, evolutionary and environmental epigenetics. In particular, by studying why stress-related experiences of organisms (e.g. exposure to toxins) can be passed onto the future generations regardless of its seemingly fitness-reducing impacts. It also aims to test if the seemingly beneficial effect of non-stress related experiences (e.g. environmental enrichment) ca ....Transgenerational Consequences of Different Environmental Experiences. The project aims to deliver an integrative overview of behavioural, evolutionary and environmental epigenetics. In particular, by studying why stress-related experiences of organisms (e.g. exposure to toxins) can be passed onto the future generations regardless of its seemingly fitness-reducing impacts. It also aims to test if the seemingly beneficial effect of non-stress related experiences (e.g. environmental enrichment) can be inherited transgenerationally. This project involves both research synthesis (e.g. meta-analysis) and experiments on zebrafish employing cutting-edge statistical, computational and molecular methods along with behavioural assays. Also, the outcomes of the synthesis are expected to guide future work in the field. Read moreRead less
The influence of breeding synchrony on avian reproductive strategies. Australia has a strong international reputation for research on avian evolutionary biology, in part, because of our diverse and unique avifauna.

In order to study such processes our collective experience strongly suggests and increasing need for geographic amalgamation of necessary and complementary molecular and biomedical techniques. We therefore request funding to establish a collaborative research laboratory in a novel research field - Evolutionary Immuno-Ecology- in which all vital aspects, from a mechanistic to an evolutionary level, can be studied at one research centre.Read moreRead less
New multi-scale seed dispersal models for improved regional weed management. This project will exploit recent advances in ecological and atmospheric modelling with the aim to build improved models of seed dispersal across landscapes to anticipate weed spread. Damaging invasive plants are rapidly transforming landscapes and altering ecosystem function worldwide. The speed and direction of weed spread determines the success or failure of costly containment and control actions, however we lack the ....New multi-scale seed dispersal models for improved regional weed management. This project will exploit recent advances in ecological and atmospheric modelling with the aim to build improved models of seed dispersal across landscapes to anticipate weed spread. Damaging invasive plants are rapidly transforming landscapes and altering ecosystem function worldwide. The speed and direction of weed spread determines the success or failure of costly containment and control actions, however we lack the ability to adequately predict spread. New models that combine micrometeorological measurements, within-canopy turbulence and topographic variation in wind flows will be designed to better predict where dispersal will occur. In this project, these improved predictions are planned to be combined with decision models to direct the management of invasive species across entire landscapes.Read moreRead less
Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project wi ....Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project will provide a new, yet crucial, perspective on how and why diseases spread. Our discoveries will help understand and manage the burden of infectious diseases from parasites in and beyond our cities and across the human-wildlife interface; essential for improving human and wildlife health in an increasingly urbanised Australia.Read moreRead less
Quantifying tree and soil respiration and their responses to global change. The Australian Greenhouse Office, as well as independent analysis, recognizes that belowground processes must be better quantified if Australia's contributions to atmospheric concentrations of greenhouse gases (GG) are to be firmly based.

The Australian Greenhouse Office, as well as independent analysis, recognizes that belowground processes must be better quantified if Australia's contributions to atmospheric concentrations of greenhouse gases (GG) are to be firmly based. A major issue is the lack of dedicated research focused on soil and plant root emissions of GG and, in particular, a lack of testing of methodologies suited to Australian soils and conditions. This project will address these concerns. We will also be addressing the clear need for further training of PhD qualified researchers in the field of climate change. Read moreRead less
