Revisiting the ontogeny of vocal learning in birds: from neuron to fitness. This project aims to test the hypothesis that acoustic exposure prior to hatching directly affects gene expression, neural development, behaviour and consequently fitness, in wild populations of songbirds. Recent research suggests that animals are receptive to acoustic parental signals long before birth and may use such previously unrecognised signals to make adaptive developmental decisions. This project will quantify t ....Revisiting the ontogeny of vocal learning in birds: from neuron to fitness. This project aims to test the hypothesis that acoustic exposure prior to hatching directly affects gene expression, neural development, behaviour and consequently fitness, in wild populations of songbirds. Recent research suggests that animals are receptive to acoustic parental signals long before birth and may use such previously unrecognised signals to make adaptive developmental decisions. This project will quantify the effect on neural development and vocal learning in embryonic birds, employing a model songbird species. The outcomes of this study will transform our understanding of the adaptive potential of prenatal vocal learning, which will have significant benefits for human speech and language development.Read moreRead less
Avian embryonic perception: what role for good vibrations? It has long been recognised that animals perceive environmental information before they are born. This project will test for the first time whether such avian communication systems rely on vibrations. We will test the hypothesis that cryptic communication using rhythmic vibration, is essential for embryonic birds to sense parental cues regarding rising temperatures, by measuring neural control in adults, as well as embryonic perception a ....Avian embryonic perception: what role for good vibrations? It has long been recognised that animals perceive environmental information before they are born. This project will test for the first time whether such avian communication systems rely on vibrations. We will test the hypothesis that cryptic communication using rhythmic vibration, is essential for embryonic birds to sense parental cues regarding rising temperatures, by measuring neural control in adults, as well as embryonic perception and response. By experimentally manipulating family communication we will demonstrate the potential for prenatal vibrations to alter developmental outcomes, enriching our understanding of avian sensory development.These data are important for the commercial poultry industry and for captive breeding programs.

Size matters: elephantoid dispersal, evolution, paleoecology and extinction in Asia. This project will investigate the natural history of the once widespread elephant lineages in Asia by studying their fossils and unlocking chemical archives from their teeth. It will provide new insights into their adaptive responses to climate change and life on islands, interactions with humans and the factors that eventually led to their demise.
Integrating fossils and genomes to resolve the early evolution of snakes. This project aims to address a high-profile evolutionary controversy – the origin of snakes – by reconciling the anatomical and fossil evidence with the burgeoning genomic data. New genomic data surprisingly links snakes with the un-snakelike iguana, prompting claims that the genetic and the fossil/anatomical data are irreconcilable. The project aims to evaluate these key fossils, and reptile anatomy in general, in light o ....Integrating fossils and genomes to resolve the early evolution of snakes. This project aims to address a high-profile evolutionary controversy – the origin of snakes – by reconciling the anatomical and fossil evidence with the burgeoning genomic data. New genomic data surprisingly links snakes with the un-snakelike iguana, prompting claims that the genetic and the fossil/anatomical data are irreconcilable. The project aims to evaluate these key fossils, and reptile anatomy in general, in light of the new genomic tree. This has potential to greatly elucidate major evolutionary changes across the lizard-snake transition (for example, extensive mobility in the snake skull). The project also plans to assess the long-term evolutionary consequences of ‘snakiness’, such as the hypothesised irreversibility of limb loss, and increased resilience to mass extinction.Read moreRead less

Summary
Pre-natal communication in adaptation to hot climate. This project aims to reveal how birds programme their offspring for a warming world, by communicating acoustically with their embryos. Most animals, including humans, can hear external sounds before birth, but it is not known what function this plays. An Australian bird calls to its eggs at high ambient temperatures, which alters nestling growth and survival. This project will show the physiological effects involved and the consequences for a ....Pre-natal communication in adaptation to hot climate. This project aims to reveal how birds programme their offspring for a warming world, by communicating acoustically with their embryos. Most animals, including humans, can hear external sounds before birth, but it is not known what function this plays. An Australian bird calls to its eggs at high ambient temperatures, which alters nestling growth and survival. This project will show the physiological effects involved and the consequences for adaptation to heat in wild birds. This project will elucidate whether the global reduction in animal body size is an adaptive response to rising temperatures, and research the therapeutic benefits of pre-natal sounds.Read moreRead less
Modelling collective behaviour to protect social insect ecosystem services. This project aims to use mathematical models and computer simulations and biological experiments to investigate how social insects adapt to environmental stress, for example due to climate change and pollution. Fundamental to the adaptability of social insects are the complex mechanisms that allow colonies to maintain a carefully balanced division of labour (DOL). This project builds on evolutionary game theory to develo ....Modelling collective behaviour to protect social insect ecosystem services. This project aims to use mathematical models and computer simulations and biological experiments to investigate how social insects adapt to environmental stress, for example due to climate change and pollution. Fundamental to the adaptability of social insects are the complex mechanisms that allow colonies to maintain a carefully balanced division of labour (DOL). This project builds on evolutionary game theory to develop a new approach for analysing how environmental factors impact on DOL and thus colony viability. The project will deliver new methods to assess and predict the impact of environmental stress This will ultimately help to protect these keystones of biodiversity and the significant ecosystem services they provide as pest-control agents, through pollination, seed dispersal, and soil conditioning.Read moreRead less
Effects of uptake of carbon and nutrients (nitrogen, phosphorous and silicon) on pH among phytoplankton species: implications for ocean acidification feedback mechanisms. Anthropogenic CO2 emission has caused a decrease in the ocean pH, which may affect coral reefs. The project will study two processes, as the feedback mechanisms, which can increase pH in seawater, uptake of additional CO2 by algae directly and stimulated by the human input of nitrogen and phosphorus.

Summary
Enhancement of South Australian high-performance computing facilities. These facilities will enable the efficient use of high-performance computing and will more than double the capability provided by eResearch SA for South Australian researchers. They will support large-scale applications, running over many processors in parallel (high-performance computing) or large numbers of single processors (high-throughput computing).
Does physiological plasticity of individuals render populations resilient to climate change? Abrupt environmental changes can put natural populations at risk of extinction. The project will show to what extent individuals can compensate for temperature changes and thereby render populations resilient to climate change. This research will make theoretical advances and improve the power to predict impacts of future climate change.
Limits to the resilience of Australian forests and woodlands to drought. Water availability is a primary determinant of plant growth and the distribution of plant species and communities throughout the world. In Australia, climate change is predicted to result in increasing temperatures and shifting precipitation patterns, leading to more intense droughts in some areas. This project will examine the resilience of Australian forests and woodlands to drought under both current and future climate s ....Limits to the resilience of Australian forests and woodlands to drought. Water availability is a primary determinant of plant growth and the distribution of plant species and communities throughout the world. In Australia, climate change is predicted to result in increasing temperatures and shifting precipitation patterns, leading to more intense droughts in some areas. This project will examine the resilience of Australian forests and woodlands to drought under both current and future climate scenarios. The results of this work will feed into the new generation of dynamic global vegetation models, allowing for robust prediction of changes in the structure and productivity of Australian vegetation communities in the face of rapid climate change.Read moreRead less
