A comparative genomics approach to understanding host-endosymbiont interactions. Australia's unique ecosystems are vulnerable to invasion by exotic pests that threaten agriculture and human health. The bacterial symbiont Wolbachia is found in many major pests of agricultural and medical importance. Our results will give insights into how Wolbachia spreads into host populations and improve its use as a tool to impair insect transmission of disease, e.g. as an agent to carry genes into an insect p ....A comparative genomics approach to understanding host-endosymbiont interactions. Australia's unique ecosystems are vulnerable to invasion by exotic pests that threaten agriculture and human health. The bacterial symbiont Wolbachia is found in many major pests of agricultural and medical importance. Our results will give insights into how Wolbachia spreads into host populations and improve its use as a tool to impair insect transmission of disease, e.g. as an agent to carry genes into an insect population that limit disease transmission. Our results will also make fundamental contributions to understanding host-parasite evolution, host-parasite communication, and insect developmental processes, and will be of interest to a large international community of researchers in this field.

Estimation of non-additive genetic variance for complex traits using genome-wide single nucleotide polymorphyisms and sequence data. Finding genes for traits of importance in agriculture, ecology and human health depends on understanding the genetic basis of these traits. This project will investigate whether variation in traits in humans, cattle and wild sheep are influenced by gene-gene interactions.
The genetic architecture and evolution of quantitative traits. Most important traits are controlled by many genes and by the environment, however there is little knowledge of how many genes are involved in these complex traits and what their effects are. This project will describe the number of genes and their effects for complex traits in humans and livestock and explain how these genes evolve.

Australia will further enhance its role as an innovator in the archaeology of SE Asia through this cross-disciplinary, international collaboration on the mobility, health, age and diet in ancient Cambodia. Local collaborations will be expanded and academic and cultural relations with Cambodia will be reinforced and strengthened. This research will expand understanding of Cambodian history and underscore its pivotal role in mainland SE Asian archaeology. Australia's advancement of knowledge about Cambodia's rich cultural antiquity will be recognized worldwide by a global community acutely mindful of the losses to culture and heritage endured by Cambodia in the recent past.Read moreRead less
Genetic architecture and evolution of complex traits across populations. Most human traits have a genetic component and display substantial diversity within and among populations. How natural selection changes and maintains genetic variation in human traits is a long-standing question in evolution that the proposed project aims to answer. Using innovative statistical methods and largest genomic “big” datasets ever across populations of different ancestral backgrounds, this project expects to gen ....Genetic architecture and evolution of complex traits across populations. Most human traits have a genetic component and display substantial diversity within and among populations. How natural selection changes and maintains genetic variation in human traits is a long-standing question in evolution that the proposed project aims to answer. Using innovative statistical methods and largest genomic “big” datasets ever across populations of different ancestral backgrounds, this project expects to generate new knowledge on the roles of natural selection in shaping the genetic variation in traits and identify key factors that drive the differentiation of human populations. These outcomes will significantly improve our understanding on the evolution of human traits and adaptation of populations to changing environments.Read moreRead less
Mutational genetic variance and the fitness optimum. Mutation and selection are ubiquitous forces in nature, but we do not understand how genetic variation produced by mutation is maintained in the presence of selection that depletes it. The recent discovery of apparent stabilising selection on traits with high levels of genetic variation provides a new approach to understanding this paradox.
Agriculture and the Late Bronze Age collapse of the Hittite Empire. National benefit will be accrued through the major scholarly contribution the project makes to a key debate in world archaeology, namely the extent to which environmental change affected ancient complex societies, especially climate change. As such it fosters an awareness of world cultures and the interrelation between political stability and environmental change.

National benefit will be accrued through the major scholarly contribution the project makes to a key debate in world archaeology, namely the extent to which environmental change affected ancient complex societies, especially climate change. As such it fosters an awareness of world cultures and the interrelation between political stability and environmental change. The project also will encourage international collaboration between Australian, Turkish and Japanese scholars and will provide training for several research scholars in an area of archaeology in which Australia has a recognised major deficit, namely archaeobotany.Read moreRead less
The nature of standing genetic variation. This project aims to expand understanding of the genetic variation underlying phenotypic differences among individuals. The nature of genetic variation has broad consequences across biology, from the detection of causal genetic variants to the adaptation of natural populations. This project will take a novel experimental approach to test several long-standing assumptions about the effects of new mutations on individual traits and their joint pleiotropic ....The nature of standing genetic variation. This project aims to expand understanding of the genetic variation underlying phenotypic differences among individuals. The nature of genetic variation has broad consequences across biology, from the detection of causal genetic variants to the adaptation of natural populations. This project will take a novel experimental approach to test several long-standing assumptions about the effects of new mutations on individual traits and their joint pleiotropic effect on fitness. By expanding our understanding of how mutation, selection and drift interact, this project could provide significant improvements in our understanding of the genetic basis of phenotypes, and our ability to predict phenotypic evolution.Read moreRead less
Understanding rapid adaptation to new environments. This project aims to improve understanding of the process of rapid adaptation. Through both in situ changes and movement of individuals, populations are increasingly encountering new environments, where they risk extinction or become invasive. The fate of populations is determined by how rapidly they adapt to their new environmental conditions. Recent theory predicts adaptation to novel environments is fastest when selection acts on environment ....Understanding rapid adaptation to new environments. This project aims to improve understanding of the process of rapid adaptation. Through both in situ changes and movement of individuals, populations are increasingly encountering new environments, where they risk extinction or become invasive. The fate of populations is determined by how rapidly they adapt to their new environmental conditions. Recent theory predicts adaptation to novel environments is fastest when selection acts on environment-specific genetic variation. This project will test this prediction using novel manipulations. Better understanding of adaptation will allow better prediction of the risks of both extinction and invasiveness of natural populations.Read moreRead less

It is of enormous national benefit to develop intellectual innovations that set Australia apart from its neighbours and establish its position as a regional leader in science. Because the Australasian region relies heavily on primary resource exploitation, intellectual developments are crucial for sustainable economic growth. Understanding how societies meet the challenges of resource depletion, landscape degradation, drought and population increase can be monitored with archaeological data over hundreds of years. Our research seeks to use an innovative technique for precisely dating major changes in Oceanic societies over the past 500 years, which will provide insights into how modern communities can cope with these problems today.
