Summary
Interplay between plasticity and senescence. This project aims at bridging two fundamental human stressors together in a quantitative genetic framework. The environment changes globally on a huge scale coupled with effect on the age-structures and genetic composition of countless populations by over-harvesting and exploitation. This project will provide significant benefits, such as potential strategies of dealing with future human-induced changes more effectively.
Adaptive capacity of marine invertebrates in a climate change ocean. As the oceans simultaneously warm and acidify, prospects for marine biota are of concern. This project aims to determine the potential for phenotypic adjustment and evolutionary adaptation. To discern the roles of phenotype and genotype in marine invertebrate stress tolerance this project endeavours to use selection experiments, long-term rearing and quantitative genetics . A focus on vulnerable calcification systems could dete ....Adaptive capacity of marine invertebrates in a climate change ocean. As the oceans simultaneously warm and acidify, prospects for marine biota are of concern. This project aims to determine the potential for phenotypic adjustment and evolutionary adaptation. To discern the roles of phenotype and genotype in marine invertebrate stress tolerance this project endeavours to use selection experiments, long-term rearing and quantitative genetics . A focus on vulnerable calcification systems could determine genetic mechanisms underlying impaired growth. Investigation of species from the east Australia latitudinal thermal gradient, a global change hot spot could generate insights into biological responses and adaptive potential in a changing ocean and on time scales relevant to resource managers to understand the challenges faced by marine biota.Read moreRead less
Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for p ....Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for predicting climate change resilience that can be applied to many species. The intended benefits include increasing our understanding of the potential for native bees to act as future pollinators in Australia’s natural and agro-ecosystems, and guide policy and management decisions to better protect and conserve our bee fauna.Read moreRead less
The role of epigenetic modifications in bovid adaptation to environmental change. This project will explore the role of epigenetic change, where gene expression is regulated without changing the deoxyribonucleic acid (DNA) sequence, in how animals adapt to rapid climate change. This project will trace epigenetic markers in ancient bison and cows through 30,000 years of climate change, and identify key adaptive genes for the cattle industry.
The nutritional geometry of parental diet. This project aims to investigate the effects of ancestors’ diet on descendants’ development and performance. Recognition that an individual’s diet can affect its descendants’ features and health influences biology and medicine, but limitations of conventional research methodologies make understanding such effects incomplete. The Nutritional Geometry framework enables researchers to analyse effects of diet composition as complex response surfaces, and ha ....The nutritional geometry of parental diet. This project aims to investigate the effects of ancestors’ diet on descendants’ development and performance. Recognition that an individual’s diet can affect its descendants’ features and health influences biology and medicine, but limitations of conventional research methodologies make understanding such effects incomplete. The Nutritional Geometry framework enables researchers to analyse effects of diet composition as complex response surfaces, and has recently been used in research on parental diet effects. Building on this breakthrough, this project intends to analyse the effects of ancestors’ diet, and test hypotheses relevant to evolution, ecology and human health.Read moreRead less

Summary
Unifying cornerstones of social evolution: theory and application. This proposal aims to reconcile and unify alternative methods in social evolution theory, one of the foundations of our modern understanding of evolutionary and behavioural ecology. Social evolution has been controversial, but recent years have seen major developments. By combining mathematical models and empirical data, this project expects to end the controversies by removing boundaries between theoretical approaches. Specific ....Unifying cornerstones of social evolution: theory and application. This proposal aims to reconcile and unify alternative methods in social evolution theory, one of the foundations of our modern understanding of evolutionary and behavioural ecology. Social evolution has been controversial, but recent years have seen major developments. By combining mathematical models and empirical data, this project expects to end the controversies by removing boundaries between theoretical approaches. Specific applications of theory include social insect evolution, individuality and selection in plants. Unification of theory is expected to enhance research capacity in Australia and internationally.Read moreRead less
Expanding gene-environment causality in evolutionary genetics. This project aims to investigate how environmental experiences shape phenotypes, engender variance in populations and ultimately contribute to evolution. It targets new discoveries for how environmental effects can multiply throughout ontogeny and/or propagate across generations. Although widely speculated to support new evolutionary paradigms, such knowledge lacks scrutiny according to the formal metric of quantitative genetics. Thi ....Expanding gene-environment causality in evolutionary genetics. This project aims to investigate how environmental experiences shape phenotypes, engender variance in populations and ultimately contribute to evolution. It targets new discoveries for how environmental effects can multiply throughout ontogeny and/or propagate across generations. Although widely speculated to support new evolutionary paradigms, such knowledge lacks scrutiny according to the formal metric of quantitative genetics. This project seeks to expose guppy pedigrees to unique manipulations and reconcile adaptive evolution across captive and wild populations. The outcome is expected to address knowledge gaps in the life and human sciences and potentially inform goals in primary production and conservation.Read moreRead less
Dimensions of ecological strategy for plants. A more fundamental understanding will be sought about the architecture and ecology of vegetation and why it varies around the world. Under a high- CO2 future, models will be needed that operate through fundamental mechanisms of evolution, competition and physiology, rather than through extrapolation from present-day plants.

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.
Frayed at the edges? Integrating evolutionary genetics into the study of species distributional limits. Restricted species, like those in rainforests, represent the vast majority of biodiversity, but they face high risks of extinction due to climate change unless they can adapt. Using butterflies as a model, this project will examine whether rainforest restricted species are able to adapt to future climate change and provide insight into their extinction risk.
