This project aims to generate unprecedented insights into the fangs of venomous snakes, focusing on elapids (taipans, tiger snakes etc). We will examine fang shape diversity, correlation with behavior and ecology, evolutionary history, and biomechanical properties. Data will be collected using cutting-edge micro-CT technology and analysed using 3D geometric morphometrics, computer simulations, and advanced phylogenetic techniques. This should greatly improve understanding of the evolution of venom fangs in all snakes. Other benefits include a large 3D reference database allowing identification of fossil fangs, with applications for studies of past climates, and a characterisation of fang biomechanics, relevant to biodesign and biomimicry.Read moreRead less
The nature and consequences of environmentally-generated phenotypic variation in natural populations. The ambient environment can generate both heritable and non-heritable variation in individual traits, but the role of such variation in evolution is poorly understood. This project will use a powerful model organism, the Australian neriid flies, to elucidate the evolutionary implications of environmentally-generated variation.
Islands of rocks: geckos as a model system to understand patterns of biodiversity, endemism and speciation in the Kimberley. Australia is renowned for its diversity of lizards, yet a plethora of new "cryptic" gecko species continue to be discovered. The project will densely sample the complex Kimberley to understand the evolution of its geckos, which will shed light on true levels of species diversity and the geological and environmental history of this biodiversity hotspot.
A molecular/morphological view of animal evolution based on marsupials. This project aims to provide high-accuracy methods of evolutionary inference extendable to nearly all other organisms. It aims to research the evolution of animal diversity and calibrate evolutionary timescales on a case study of marsupial mammals, and differentiate between internal and external factors that govern animals’ ability to adapt and diversify. The project will collate a large, open-source three-dimensional catalo ....A molecular/morphological view of animal evolution based on marsupials. This project aims to provide high-accuracy methods of evolutionary inference extendable to nearly all other organisms. It aims to research the evolution of animal diversity and calibrate evolutionary timescales on a case study of marsupial mammals, and differentiate between internal and external factors that govern animals’ ability to adapt and diversify. The project will collate a large, open-source three-dimensional catalogue of the evolving marsupial skeleton, which could provide a detailed and publicly accessible narrative of the evolutionary past and future adaptability of Australian marsupials. The proposed development of methods to quantify the effect of past and present biodiversity crises (e.g. environmental change) is expected to inform longer-term conservation planning.Read moreRead less
Understanding evolution in natural systems using robotic models. This project aims to build biologically-inspired robotic and computational systems, and then modify these in ways which are either not possible, or have not yet occurred in natural systems. A comparison of these two systems will then allow a quantitative understanding of how well optimised biological structures are and where the limitations to optimisation lie. Expected outcomes include advancing the understanding of evolutionary p ....Understanding evolution in natural systems using robotic models.

Fitting non-Gaussian diffusion models to evolutionary data: towards a generalized framework for phylogenetic comparative analyses. This project aims to develop cutting-edge statistical methods for evolutionary biology in order to answer big questions using data derived from multiple species. Such methods are needed because of the variety of multi-species data that are becoming available, which cannot be dealt with correctly using current methods. The research is significant because it will provi ....Fitting non-Gaussian diffusion models to evolutionary data: towards a generalized framework for phylogenetic comparative analyses. This project aims to develop cutting-edge statistical methods for evolutionary biology in order to answer big questions using data derived from multiple species. Such methods are needed because of the variety of multi-species data that are becoming available, which cannot be dealt with correctly using current methods. The research is significant because it will provide a new way of fitting a wide class of statistical models to evolutionary data, in a very general setting. Further, this project will unite current methodology in a broader framework so that the proposed new methods are a generalisation of currently accepted theory. The outcomes will include a freely-available software package that implements the methods in a user-friendly form.Read moreRead less
Efficient phylogenetic methods that manage the curse of genomic complexity. This project aims to develop new methods and software to infer the evolutionary history of organisms using genomic data. These new phylogenomic methods need to take account of the complexity of evolutionary processes and/or patterns in time (along the evolutionary tree) and space (along the genome). This project is significant because these methods must merge mathematics and statistics with High-Performance Computing to ....Efficient phylogenetic methods that manage the curse of genomic complexity. This project aims to develop new methods and software to infer the evolutionary history of organisms using genomic data. These new phylogenomic methods need to take account of the complexity of evolutionary processes and/or patterns in time (along the evolutionary tree) and space (along the genome). This project is significant because these methods must merge mathematics and statistics with High-Performance Computing to handle the huge quantities of genetic data and the complexity of evolution itself. An important expected outcome of this project will be the development and release of freely-available software that incorporates these new methods. This project expects to benefit scientists who need to infer phylogenies from genomic data. Read moreRead less

Summary
The drivers of genome evolution and diversification in marsupials. This project aims to investigate the impact of the four basic forces of evolution, mutation, selection, neutral drift, and gene flow, on the genome. Genome-scale data have a signature of these forces and extracting it would greatly improve the quality of evolutionary models fit to the data, but the framework to identify the evolutionary forces has not been developed. This project will develop tests for assessing the impact of the ....The drivers of genome evolution and diversification in marsupials. This project aims to investigate the impact of the four basic forces of evolution, mutation, selection, neutral drift, and gene flow, on the genome. Genome-scale data have a signature of these forces and extracting it would greatly improve the quality of evolutionary models fit to the data, but the framework to identify the evolutionary forces has not been developed. This project will develop tests for assessing the impact of the primary evolutionary forces on the genome, and test these methods using simulations. The new framework of genomic analysis will be disseminated through an intuitive software package, and will be used to estimate with unprecedented confidence the history of diversification and genome evolution of marsupials.Read moreRead less
