How beetles harness near-infrared properties to enhance energy efficiency. This project aims to discover how animals use nanophotonic structures to manipulate near infra-red light for thermal control and visual information. Almost nothing is currently known about the mechanism, function and evolution of near-infrared properties in animals, despite their potential importance for maintaining body temperatures within the critical thermal limits for survival. The project uses multidisciplinary techn ....How beetles harness near-infrared properties to enhance energy efficiency. This project aims to discover how animals use nanophotonic structures to manipulate near infra-red light for thermal control and visual information. Almost nothing is currently known about the mechanism, function and evolution of near-infrared properties in animals, despite their potential importance for maintaining body temperatures within the critical thermal limits for survival. The project uses multidisciplinary techniques from optical physics, physiology and evolutionary biology to reveal near-infrared adaptations in socially and economically important Christmas beetles. The intended outcomes include a bio-informed blueprint for a new class of functional nanomaterials that enhance energy efficiency.Read moreRead less
Unravelling the role of heteroplasmy in mitochondrial adaptation. This project aims to unravel the evolutionary implications of heteroplasmy – a scenario in which multiple mitochondrial DNA genotypes exist in one individual. Recent studies indicate heteroplasmy is widespread, and can be caused by paternal transmission of mtDNA. But the effects of heteroplasmy on evolutionary processes remain unknown. Leveraging state-of-the-art methods, this project expects to generate new knowledge in the areas ....Unravelling the role of heteroplasmy in mitochondrial adaptation.

Evolutionary limits. This project aims to understand the processes that limit adaptation to rapid environmental change. Adaption to rapid environmental change determines population persistence. Species with restricted distributions may lack the genetic variation necessary to adapt to changing environments, although they represent the vast majority of biodiversity. Understanding why they lack the necessary genetic variation for adaptation is important for identifying and managing vulnerable biolo ....Evolutionary limits. This project aims to understand the processes that limit adaptation to rapid environmental change. Adaption to rapid environmental change determines population persistence. Species with restricted distributions may lack the genetic variation necessary to adapt to changing environments, although they represent the vast majority of biodiversity. Understanding why they lack the necessary genetic variation for adaptation is important for identifying and managing vulnerable biological systems. This project will empirically determine the contribution of mutations to key traits to better understand what limits evolutionary adaptation. Better prediction of extinction risk should inform conservation and biodiversity management.Read moreRead less
Adaptation by DNA download: Experimental evolution of a pangenome. This project aims to understand how microbes adapt when they can directly “download" new genes from their surrounding environment, or from other types of bacteria. Specifically, the proposed research will carry out the largest-scale measurements of the fitness effects of horizontally transferred genetic variation, to discover how each of these genes interacts with the environment, and with other genes. This project is expected to ....Adaptation by DNA download: Experimental evolution of a pangenome.

Specifically, the proposed research will carry out the largest-scale measurements of the fitness effects of horizontally transferred genetic variation, to discover how each of these genes interacts with the environment, and with other genes. This project is expected to generate new knowledge in the fields of microbial evolution and microbiome science. The benefits of this cutting-edge research will be to strengthen Australia’s research capacity in these rapidly developing fields and to train a new generation of interdisciplinary scientists.Read moreRead less
Integrating evolution and plasticity into predictions of population persistence in a changing climate: adaptation or extinction? To effectively manage biodiversity at a time of rapid environmental change, Australia needs accurate predictions of how human alterations to climate and habitat will affect species. This project integrates evolution and spatial ecology to develop new tools for predicting and understanding how species will respond to environmental change.

This project aims to predict the future distributions of local and invasive mosquito species under climate change by testing their ability to adapt to hot, cold and dry environments. The project expects to generate new knowledge by identifying traits that underpin climate change adaptation in mosquitoes. Expected outcomes of this project include an enhanced understanding of future mosquito distributions through new predictive models that incorporate adaptive changes. This should provide significant social and economic benefits, with outcomes intended to improve the management of local pest mosquitoes and prepare Australia to tackle invasive mosquito threats.Read moreRead less
