Summary
Evolutionary and environmental basis of CO2 tolerance in coral reef fishes. This project aims to examine the effects of ocean acidification on coral reef fishes due to increasing atmospheric carbon dioxide (CO2). Physiological performance of fish vary under elevated CO2, but behaviour is consistently, negatively impacted. This project aims to investigate evolutionary trade-offs between behaviour and performance, physiological mechanisms key to compromising, maintaining, or enhancing metabolic pe ....Evolutionary and environmental basis of CO2 tolerance in coral reef fishes. This project aims to examine the effects of ocean acidification on coral reef fishes due to increasing atmospheric carbon dioxide (CO2). Physiological performance of fish vary under elevated CO2, but behaviour is consistently, negatively impacted. This project aims to investigate evolutionary trade-offs between behaviour and performance, physiological mechanisms key to compromising, maintaining, or enhancing metabolic performance under elevated CO2, and the importance of habitat in how fish respond to elevated CO2. As fish play critical roles in marine ecosystems by structuring food webs and driving ecological processes, this information will be critical for predicting the effects of ocean acidification on marine ecosystems and biodiversity.Read moreRead less
A modelling analysis of the implications of biogenic feedbacks on environment for the adaptation of ecosystems. The sustainable management of Australia's living resources depends critically on a deep understanding of the fundamental properties of ecosystems. These properties will determine the response of an ecosystem to perturbation. Anthropogenic perturbation of ecosystems, whether instantiated by living resource harvesting, habitat destruction, species invasions, pollution or climate change, ....A modelling analysis of the implications of biogenic feedbacks on environment for the adaptation of ecosystems. The sustainable management of Australia's living resources depends critically on a deep understanding of the fundamental properties of ecosystems. These properties will determine the response of an ecosystem to perturbation. Anthropogenic perturbation of ecosystems, whether instantiated by living resource harvesting, habitat destruction, species invasions, pollution or climate change, is the greatest current threat to Australia's biodiversity and hence the continued functioning of the systems that we rely on for maintaining our environment in a habitable state and for providing economic benefit. This research will attempt to discover some of these properties, and assess their implications for the sustainably management of our environment.Read moreRead less

Understanding evolution in natural systems using robotic models. This project aims to build biologically-inspired robotic and computational systems, and then modify these in ways which are either not possible, or have not yet occurred in natural systems. A comparison of these two systems will then allow a quantitative understanding of how well optimised biological structures are and where the limitations to optimisation lie. Expected outcomes include advancing the understanding of evolutionary p ....Understanding evolution in natural systems using robotic models.

A comparison of these two systems will then allow a quantitative understanding of how well optimised biological structures are and where the limitations to optimisation lie. Expected outcomes include advancing the understanding of evolutionary processes, and will provide significant benefits, such as aiding the manufacture of efficient autonomous robots.Read moreRead less
Why does the genetic nearly-null subspace exist? This project aims to determine why nearly-null genetic subspaces exist by simultaneously measuring the input of new mutational variance in these nearly-null subspaces and the selection that acts on these new mutations to result in the observed low levels of standing genetic variance. The ability of organisms to evolve in response to human disturbance, translocation to new environments, or climate variation is governed by the availability of geneti ....Why does the genetic nearly-null subspace exist? This project aims to determine why nearly-null genetic subspaces exist by simultaneously measuring the input of new mutational variance in these nearly-null subspaces and the selection that acts on these new mutations to result in the observed low levels of standing genetic variance. The ability of organisms to evolve in response to human disturbance, translocation to new environments, or climate variation is governed by the availability of genetic variation. Recent advances in multivariate genetic analysis have demonstrated that a substantial proportion of a phenotype described by quantitative traits has very little genetic variance associated with it, and will therefore tend to be subjected to evolutionary limitsRead moreRead less
Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and gene ....Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and genetics to address questions such as how and why ancestral macropods descended from the trees and evolved bipedal hopping, and the upper size limits of the kangaroo “body plan”. This should improve our understanding of the long-term effects of climate change on marsupials, and provide a test of key placental-based evolutionary models.Read moreRead less

Conserving the evolutionary processes that generate coral reef biodiversity. Coral reefs have evolved to become the most biodiverse marine ecosystem we know. They now face an uncertain future due to escalating human impacts and this project aims to investigate how these disturbances change the evolutionary processes that generate and maintain life on the reef.

Coral reefs have evolved to become the most biodiverse marine ecosystem we know. They now face an uncertain future due to escalating human impacts and this project aims to investigate how these disturbances change the evolutionary processes that generate and maintain life on the reef. Using an interdisciplinary approach, this project seeks to create new knowledge and demonstrate how evolutionary theory can be used to advance biodiversity conservation. Other expected outcomes include developing new techniques and an enhanced capacity to solve conservation problems through cross-disciplinary and cross-institutional collaborations. This should benefit the conservation of Australia’s coral reef biodiversity through improved management policies.Read moreRead less
Wild eco-evolutionary dynamics: the decline of an iconic Australian bird. This project aims to dissect the ecological and evolutionary processes causing a decline in an iconic Australian bird species. Studies that can properly test explanations for declines in wild populations are rare. This project aims to test how environmental and genetic processes shape individual traits, how these traits determine fitness and how changes in individual fitness affect population dynamics.

This project aims to provide high-accuracy methods of evolutionary inference extendable to nearly all other organisms. It aims to research the evolution of animal diversity and calibrate evolutionary timescales on a case study of marsupial mammals, and differentiate between internal and external factors that govern animals’ ability to adapt and diversify. The project will collate a large, open-source three-dimensional catalogue of the evolving marsupial skeleton, which could provide a detailed and publicly accessible narrative of the evolutionary past and future adaptability of Australian marsupials. The proposed development of methods to quantify the effect of past and present biodiversity crises (e.g. environmental change) is expected to inform longer-term conservation planning.Read moreRead less
