Discovering nature's photonic devices to control light and heat. This project aims to discover how and why beetles and butterflies reflect near-infrared light. Reflection of near-infrared radiation may be critical to prevent overheating, yet its role in thermal protection remains largely unexplored. The project will integrate evolutionary biology, optical physics and biophysics to reveal the diversity, mechanism, function and evolution of near-infrared signatures. Expected outcomes include the d ....Discovering nature's photonic devices to control light and heat. This project aims to discover how and why beetles and butterflies reflect near-infrared light. Reflection of near-infrared radiation may be critical to prevent overheating, yet its role in thermal protection remains largely unexplored. The project will integrate evolutionary biology, optical physics and biophysics to reveal the diversity, mechanism, function and evolution of near-infrared signatures. Expected outcomes include the discovery of nature’s solutions to selection for both optical (camouflage, communication) and thermal functions. The project will have significant benefits such as creating opportunities to develop biomimetic and bioinspired materials to enhance energy efficiency, which will have significant economic and environmental benefits.Read moreRead less
Exploring the unseen: the adaptive significance of animal-visible and infrared colour change. Our research on benefits of rapid colour change in cold-blooded animals, spanning the full spectrum of solar energy, will provide novel insights into the adaptive significance of animal colour patterns. It will also provide a natural model for development of advanced colour-changing materials with a wide range of applications.
A life-course approach to the nutrition-lifespan-reproduction nexus. This project aims to address the “cost of reproduction”, where lifespan and fecundity are negatively correlated. Bringing together nutritional geometry and evolutionary theory, to the project will produce an over-arching theory of why animals have finite lifespans and limited reproductive capacity. Benefits include developing research strategies for managing the nexus between diet, reproduction and lifespan in animals and human ....A life-course approach to the nutrition-lifespan-reproduction nexus. This project aims to address the “cost of reproduction”, where lifespan and fecundity are negatively correlated. Bringing together nutritional geometry and evolutionary theory, to the project will produce an over-arching theory of why animals have finite lifespans and limited reproductive capacity. Benefits include developing research strategies for managing the nexus between diet, reproduction and lifespan in animals and humans, placing Australia at the forefront of a paradigm shift in understanding the relationship between diet, reproduction and lifespan.Read moreRead less
Unlocking telomere effects on life, death and fitness in a warming world. Few things in biology provoke such a strong desire for understanding as when adult death and fatal disease can be predicted early in life. A common factor linking early life stress, disease, ageing and time of death are telomeres, the protective regions at the end of each chromosome. This project aims to explicitly link telomere dynamics in free-living ectotherm populations with experimental approaches to advance our under ....Unlocking telomere effects on life, death and fitness in a warming world. Few things in biology provoke such a strong desire for understanding as when adult death and fatal disease can be predicted early in life. A common factor linking early life stress, disease, ageing and time of death are telomeres, the protective regions at the end of each chromosome. This project aims to explicitly link telomere dynamics in free-living ectotherm populations with experimental approaches to advance our understanding of parental and environmental effects on offspring telomeres and their effects later in life. This project will take advantage of one of the world’s longest datasets on ectotherm responses to climate to provide new knowledge of how telomeres affect fitness and the role that the environment plays.Read moreRead less

Summary
Sydney basin multi-purpose spectral analysis facility for evolutionary and ecological studies. This near infrared spectroscopy facility at The University of New South Wales will serve the Sydney area biological research community. Near infrared spectroscopy provides quick and robust estimates of key properties of animal and plant tissues, such as age, species and chemical composition.
Inflammation as an early form of maternal-fetal signalling in pregnancy. The project aims to understand the role of inflammatory signalling in marsupial pregnancy. This project is expected to explain why inflammation, a processes normally confined to injury and infection, is a part of reproduction in live-bearing mammals. Outcomes of this project include robust measures of the capacity for, impact of, and evolution of, inflammatory signalling in marsupial pregnancy. The project will provide new ....Inflammation as an early form of maternal-fetal signalling in pregnancy. The project aims to understand the role of inflammatory signalling in marsupial pregnancy. This project is expected to explain why inflammation, a processes normally confined to injury and infection, is a part of reproduction in live-bearing mammals. Outcomes of this project include robust measures of the capacity for, impact of, and evolution of, inflammatory signalling in marsupial pregnancy. The project will provide new knowledge about the unique biology of Australia's marsupial fauna.This project will provide significant benefits, including enhanced capacity for reproduction research in Australia, new international collaborations between Melbourne and Yale, and a new explanation for the puzzling role of inflammation in pregnancy.Read moreRead less
Global differentiation of the conifer flora. Conifers are among the most widely recognised and well-loved group of plants. This project will place a global perspective on the evolutionary significance of the southern conifers. Furthermore conifers such as the Wollemi Pine, bunyas, kauris and huon pine are of considerable ecotourism value, and this project will provide a basis for interpretation of these important plants.
Drought and death: past, present and future survival limits in the Australian vegetation landscape. Science cannot predict the point at which water stress becomes lethal for plants. This research into plant water transport aims to find a new way to understand whether plant species will die or adapt to a future drier climate.
Genes in conflict in the social insects. Queen bees mate with 20 males, so it is in each male's interests to father female offspring that are more likely to become queens or reproductive workers. In contrast, queens want all workers to be sterile. This project will determine if some males pass on genes to offspring that have been modified so that their daughters are likely to become reproductive.
Insights into macroevolution using a model adaptive radiation of lizards (Lerista). Australia has arguably the greatest diversity of lizards in the world. This research will investigate how this diversity arose, using Lerista, a radiation of skinks with over 80 species spanning fully limbed to totally legless forms. We will investigate how development, geographic distribution and morphological features have influenced the evolutionary diversification of Lerista. We will also map the biodivers ....Insights into macroevolution using a model adaptive radiation of lizards (Lerista). Australia has arguably the greatest diversity of lizards in the world. This research will investigate how this diversity arose, using Lerista, a radiation of skinks with over 80 species spanning fully limbed to totally legless forms. We will investigate how development, geographic distribution and morphological features have influenced the evolutionary diversification of Lerista. We will also map the biodiversity of Lerista across Australia using (and thus testing) several alternative methods of quantifying biodiversity. Such knowledge is important as many hotspots of Lerista diversity are coming under increasing human pressure (e.g. mid-coast of WA), and many species have very localised ranges.Read moreRead less
