Testing links between life-history and genome evolution. Chromosomes are fundamental units of inheritance. They often differ in number, size and structure between species, and may also differ between individuals within a species. The evolution of chromosomes is tied to that of organisms themselves, making them important for understanding the generation and maintenance of biodiversity. Yet, our understanding of the forces that influence chromosome evolution remains limited. This project will inve ....Testing links between life-history and genome evolution. Chromosomes are fundamental units of inheritance. They often differ in number, size and structure between species, and may also differ between individuals within a species. The evolution of chromosomes is tied to that of organisms themselves, making them important for understanding the generation and maintenance of biodiversity. Yet, our understanding of the forces that influence chromosome evolution remains limited. This project will investigate the formation of unusual chains of chromosomes that are increasingly being found in various vertebrate and invertebrate taxa, using an organism in which they are most commonly found: termites. We will test the hypothesis that inbreeding drives the evolution of meiotic sex linked chromosomes.Read moreRead less
Towards a balanced veiw of parental effects: gaps, biases and opportunities. This project aims to identify and address knowledge gaps in research on parental effects by employing different methodologies (bibliometrics, systematic mapping) and developing novel methods of meta-analysis.

This should provide significant benefits by directing future research in related fields and inspiring new kinds of meta-analyses across disciplines.Read moreRead less
Determining the links between size and function in phytoplankton. Marine phytoplankton are responsible for around 50% of the carbon fixation on planet. This project will examine how phytoplankton size declines will alter marine food webs and carbon sequestration. Changes in nutrients and temperature will cause phytoplankton to be smaller but the consequences of these changes are uncertain because of a lack of knowledge regarding how changes in cell size affect function within a species. This pro ....Determining the links between size and function in phytoplankton. Marine phytoplankton are responsible for around 50% of the carbon fixation on planet. This project will examine how phytoplankton size declines will alter marine food webs and carbon sequestration. Changes in nutrients and temperature will cause phytoplankton to be smaller but the consequences of these changes are uncertain because of a lack of knowledge regarding how changes in cell size affect function within a species. This project will evolve 20 species of algae to be different sizes and estimate the consequences of these size changes for biological functions. The project will then use these data to refine global models of carbon budgets, leading to better predictions about how the global carbon pump will change. Read moreRead less
Hybridisation leading to lost sex: genomic and experimental insights. The project intends to apply advanced genomics to two classic Australian systems and quantitative genetics to one to address long-standing questions about why asexual reproduction is rare. It aims to test for rapid changes in genomes accompanying hybrid-origins of asexuals and whether this new diversity enables their ongoing evolution. The significance is that support for this hypothesis would challenge current theory for why ....Hybridisation leading to lost sex: genomic and experimental insights. The project intends to apply advanced genomics to two classic Australian systems and quantitative genetics to one to address long-standing questions about why asexual reproduction is rare. It aims to test for rapid changes in genomes accompanying hybrid-origins of asexuals and whether this new diversity enables their ongoing evolution. The significance is that support for this hypothesis would challenge current theory for why sex is so common. The expected outcome is to understand how variation is generated in natural populations with different ways of reproducing. Benefits would include significant contributions to global science, evolutionary training and potential applications in using hybridisation to manage threatened species or pests.Read moreRead less

Sensory and bioengineering approaches to predict hearing abilities in fish. This project aims to understand the factors responsible for the extraordinary diversity in the shape and size of fish ears and why some fishes are more sensitive to sound than others, which is little understood. Using innovative techniques and a multidisciplinary approach, expected outcomes of this project include the first model representing the hearing function of fish underwater. This may allow unique insights into th ....Sensory and bioengineering approaches to predict hearing abilities in fish. This project aims to understand the factors responsible for the extraordinary diversity in the shape and size of fish ears and why some fishes are more sensitive to sound than others, which is little understood. Using innovative techniques and a multidisciplinary approach, expected outcomes of this project include the first model representing the hearing function of fish underwater. This may allow unique insights into the importance of sound for fish, as well as inspire the development of new sensor technologies, including in robotics and biomedical applications. Benefits include the ability to predict the vulnerability of a fish species to noise pollution and to inform conservation strategies and policy guidelines.Read moreRead less

Evolution and role of neo-sex chromosomes in mitonuclear co-evolution. This project aims to characterize the evolution of novel, extended sex chromosomes in an Australian bird, then elucidate their role in climate-associated adaptive evolution. The species falls into two lineages bearing distinct mitochondrial genomes and nuclear-encoded mitochondrial genes carried on sex chromosomes. The project aims to test whether this extraordinary genome arrangement is splitting the species into two forms: ....Evolution and role of neo-sex chromosomes in mitonuclear co-evolution. This project aims to characterize the evolution of novel, extended sex chromosomes in an Australian bird, then elucidate their role in climate-associated adaptive evolution. The species falls into two lineages bearing distinct mitochondrial genomes and nuclear-encoded mitochondrial genes carried on sex chromosomes. The project aims to test whether this extraordinary genome arrangement is splitting the species into two forms: one adapted to hotter, drier environments, one to milder ones. This would be tackled using an innovative combination of genomics, cytogenetics, and metabolic data. Understanding the mechanisms at play would represent a major advance in ecology and evolution, with potential implications for conservation management.Read moreRead less
Are the sexes really equal? Sex-specific adaptation to environmental change. This project aims to develop a framework for accurately predicting species responses to global change. Many environmental factors will change, and species will evolve, but in a sex-specific manner. Yet understanding of how the sexes vary in their ability to evolve and adapt to such complex environmental change is lacking. This project aims to integrate environmental data with the sex-specific evolutionary potential of o ....Are the sexes really equal? Sex-specific adaptation to environmental change. This project aims to develop a framework for accurately predicting species responses to global change. Many environmental factors will change, and species will evolve, but in a sex-specific manner. Yet understanding of how the sexes vary in their ability to evolve and adapt to such complex environmental change is lacking. This project aims to integrate environmental data with the sex-specific evolutionary potential of organisms in response to multiple stressors in a spatially explicit context. The intended outcome is a powerful and general tool for predicting the impact of environmental change on the distribution and abundance of organisms. The benefits include improved conservation outcomes and better pest/disease vector control.Read moreRead less
