Dynamic evolution of mutation rates: causes and impacts on genomic analysis. This project aims to illuminate the role of variation in mutation rate in driving evolutionary change. Mutation rate is a core parameter in evolutionary analyses in essential applications including epidemiology, conservation and medicine, yet remains a “black box” given arbitrary universal values. This project will take a whole-of-biodiversity approach to understanding the forces shaping mutation rate, impact on evoluti ....Dynamic evolution of mutation rates: causes and impacts on genomic analysis. This project aims to illuminate the role of variation in mutation rate in driving evolutionary change. Mutation rate is a core parameter in evolutionary analyses in essential applications including epidemiology, conservation and medicine, yet remains a “black box” given arbitrary universal values. This project will take a whole-of-biodiversity approach to understanding the forces shaping mutation rate, impact on evolution of biodiversity and effect on accuracy and precision of phylogenetic analyses. Using Australian case studies, the expected outcome of this project will be a greater understanding variation in mutation rate between species, providing significant benefits in developing more sophisticated and reliable phylogenetic analyses.Read moreRead less

The evolution of venom and its role in shaping biodiversity. This project aims to study how venom, nature's most powerful weapon, evolves and shapes biodiversity. Using the iconic Australian and New Guinean venomous snakes as a model, this project expects to develop a novel approach to profile venom composition from museum specimens, test competing hypotheses on the evolution of venoms, and test for the association between the evolution of venoms and the evolution of diversity in species richnes ....The evolution of venom and its role in shaping biodiversity. This project aims to study how venom, nature's most powerful weapon, evolves and shapes biodiversity. Using the iconic Australian and New Guinean venomous snakes as a model, this project expects to develop a novel approach to profile venom composition from museum specimens, test competing hypotheses on the evolution of venoms, and test for the association between the evolution of venoms and the evolution of diversity in species richness and morphology. Expected outcomes include the largest venom database for any animal group and a better understanding of how venoms evolve and what role they play in earth’s biodiversity. The generated venom data has potential to be used in future studies to aid in the development of anti-venoms and drugs.Read moreRead less

Serpent sensory innovation in the evolutionary transition from land to sea. This project aims to investigate the mechanisms underlying sensory adaptation, which underpins the behavioural capacity of animals to adapt to environmental change. This research will harness innovative phenotypic imaging and genomic sequencing, to study the coordinated changes among sensory systems in a range of ecologically diverse snakes.

This research will harness innovative phenotypic imaging and genomic sequencing, to study the coordinated changes among sensory systems in a range of ecologically diverse snakes. Expected outcomes include a large database of 3D digital anatomical models from Australian and international museum collections, and new knowledge on the genetic processes influencing sensory receptor evolution in vertebrates.

Creating new stochastic models to understand the evolution of gene families. This project aims to extend stochastic modelling techniques in order to develop mathematically rigorous and biologically relevant models for the evolution of gene families. The project expects to model evolutionary processes such as gene retention, duplication and loss, and the generation of new gene functions. The duplication and subsequent re-purposing of genes is thought to be a key mechanism for generating evolution ....Creating new stochastic models to understand the evolution of gene families. This project aims to extend stochastic modelling techniques in order to develop mathematically rigorous and biologically relevant models for the evolution of gene families. The project expects to model evolutionary processes such as gene retention, duplication and loss, and the generation of new gene functions. The duplication and subsequent re-purposing of genes is thought to be a key mechanism for generating evolutionary novelty. By applying these models to genome data, the project expects to be able to quantify the importance of these different evolutionary mechanisms. The project will strengthen collaborative links between researchers in stochastic modelling and molecular evolutionary biology.Read moreRead less
Evolving rates: foundations for the next generation of molecular clocks. This project aims to investigate the causes and consequences of variation in rate of DNA sequence evolution across three kingdoms of life. Dates estimated from DNA sequences have a wide range of applications, including evolutionary biology, conservation prioritisation and epidemiology. These methods rely on accurate rate estimates, but current models lack information about the biological drivers of rates of genomic change. ....Evolving rates: foundations for the next generation of molecular clocks. This project aims to investigate the causes and consequences of variation in rate of DNA sequence evolution across three kingdoms of life. Dates estimated from DNA sequences have a wide range of applications, including evolutionary biology, conservation prioritisation and epidemiology. These methods rely on accurate rate estimates, but current models lack information about the biological drivers of rates of genomic change. This project will test reliability of current methods, identify potentially misleading estimates of disease origin or conservation priorities, and develop new approaches with empirically-informed models of rate change.Read moreRead less

Linking genomic changes to the generation of biodiversity. This project aims to provide a suite of theories, methods and software to enhance our understanding on how the generation of variation at molecular level is linked to the generation of species richness at lineage level. This new approach tests various ways that molecular changes are manifested as patterns of diversification, as revealed by genomic data analysed at the lineage level in phylogenetic studies.

This new approach tests various ways that molecular changes are manifested as patterns of diversification, as revealed by genomic data analysed at the lineage level in phylogenetic studies. Expected outcomes of this project add to a growing body of evolutionary theory and provide practical phylogenetic tools for future analyses. These should benefit Australia by improving our understanding on the formation of Australia’s biodiversity hotspots.Read moreRead less

The use of nanoparticles in heat transfer fluids, then known as nanofluids, increases their specific heat and thermal conductivity. Recent experimental works highlight that anomalous transport phenomena are evident in nanofluids that cannot be adequately described by classical conservation laws. We will extend these conservation laws to incorporate fractional operators to capture the fluid memory effects and the impact of particle clustering. Computational modelling and experimental investigations will be undertaken to identify the heat transfer mechanisms of various nanofluids. The outcomes of the work will increase knowledge on nanofluids and offer a significant opportunity to improve the efficiency of many thermal engineering systems.Read moreRead less
