Diet influences the selective advantage of mitochondrial DNA mutations. This project aims to examine critical mechanisms that affect mitochondrial DNA variation within species. It aims to test the hypothesis that mitochondrial DNA haplotypes have the potential to be under nutritionally induced balancing selection as a consequence of cellular signalling and/or Adenosine triphosphate (ATP) production by mitochondria. Diet can vary both seasonally and geographically and is a key environmental param ....Diet influences the selective advantage of mitochondrial DNA mutations. This project aims to examine critical mechanisms that affect mitochondrial DNA variation within species. It aims to test the hypothesis that mitochondrial DNA haplotypes have the potential to be under nutritionally induced balancing selection as a consequence of cellular signalling and/or Adenosine triphosphate (ATP) production by mitochondria. Diet can vary both seasonally and geographically and is a key environmental parameter that influences the ability of a species to colonise new habitats. The project plans to characterise the functional links between specific mitochondrial DNA haplotypes, mitochondrial functions and organismal traits. The expected outcome is a more precise grasp of the processes influencing genetic variation within and among species, which would inform current issues in ecology and genetics.Read moreRead less
China’s changing internal migration: patterns, causes, policy implications. China’s massive internal migration is no longer simply rural–urban and circular but highly diversified. The project aims to unravel that transition: its patterns, causes, and effects. Using 2020 census data and major longitudinal datasets, a China variant of Zelinsky’s classic mobility transition theory will be developed and deployed to identify underlying mechanisms. Among expected outcomes are powerful methods for asse ....China’s changing internal migration: patterns, causes, policy implications. China’s massive internal migration is no longer simply rural–urban and circular but highly diversified. The project aims to unravel that transition: its patterns, causes, and effects. Using 2020 census data and major longitudinal datasets, a China variant of Zelinsky’s classic mobility transition theory will be developed and deployed to identify underlying mechanisms. Among expected outcomes are powerful methods for assessing spatio-temporal migration patterns and causes, applicable to many economies especially in the Asia–Pacific. Benefits should include a new evidence base for migration and related urban–rural policy in China; and for Australia, policy inputs to improve prosperity through better relations with our biggest trading partner.Read moreRead less
Refining the timescale of human evolution and dispersal using ancient DNA. Understanding the timescale of human evolution and migration is a key goal of genetic analysis. It provides the foundation for studying our evolutionary and demographic history, our relationships to other hominids and our impact on the natural world. This project aims to use ancient DNA data to improve estimates of our evolutionary timescale.
Transnationalism and diaspora. This study aims to incorporate diaspora, circular migration and transnational linkages into demographic concepts of population and migration. Transnationalism’s replacement of permanent movements as the dominant paradigm in migration studies raises questions for demographic measurement and the study of migration. This project will use traditional demographic data with integrated quantitative and qualitative research to analyse the diaspora–migration–development nex ....Transnationalism and diaspora. This study aims to incorporate diaspora, circular migration and transnational linkages into demographic concepts of population and migration. Transnationalism’s replacement of permanent movements as the dominant paradigm in migration studies raises questions for demographic measurement and the study of migration. This project will use traditional demographic data with integrated quantitative and qualitative research to analyse the diaspora–migration–development nexus. It will study four countries to understand the characteristics of diasporas, their international linkages and their potential for enhancing development in origin countries. This is expected to generate policy advice on how to maximise the economic potential of diaspora.Read moreRead less
Rediscovering Aboriginal dispersal pathways. This project aims to use cutting-edge and transdisciplinary tools in partnership with Aboriginal people to rediscover deliberate prehistoric plant dispersal pathways along the Australian east coast. By working on three unrelated species with similar disjunct distributions, expected outcomes include detecting significant ‘cultural’ vegetation patterns that will challenge current assumptions about 'natural' plant distributions. New associations between ....Rediscovering Aboriginal dispersal pathways. This project aims to use cutting-edge and transdisciplinary tools in partnership with Aboriginal people to rediscover deliberate prehistoric plant dispersal pathways along the Australian east coast. By working on three unrelated species with similar disjunct distributions, expected outcomes include detecting significant ‘cultural’ vegetation patterns that will challenge current assumptions about 'natural' plant distributions. New associations between plant biogeography and deliberate Aboriginal manipulation of Australian environments will benefit cultural heritage, land management and restoration initiatives.Read moreRead less
Detecting and deciphering extinction dynamics under environmental change. This project aims to improve knowledge of extinction processes and impacts. It will use high-performance computing and museum collections to disentangle the ecological mechanisms that were integral in the initial decline and later extinction of Australia's unique mammals. Its significance is that it will establish the historical ranges and past population trajectories of Australian threatened mammals, pinpointing the combi ....Detecting and deciphering extinction dynamics under environmental change. This project aims to improve knowledge of extinction processes and impacts. It will use high-performance computing and museum collections to disentangle the ecological mechanisms that were integral in the initial decline and later extinction of Australia's unique mammals. Its significance is that it will establish the historical ranges and past population trajectories of Australian threatened mammals, pinpointing the combinations of ecological characteristics and threats that most affect risk of extinction from environmental change. Expected outcomes and benefits are new data and verified models to enrich conservation research and inform evidence-based solutions to better protect and recover some of Australia’s most threatened species.Read moreRead less
Dispersal and gene flow in habitat-forming algae. The temperate coast of Australia has a unique and diverse algal flora. Many of these algae play a central role in subtidal ecology by providing habitat to an astonishing diversity of taxa. Despite this, we have no understanding of levels of gene flow within and among populations of habitat forming algae or how such populations persist in nature. By addressing this lack of knowledge, my research will contribute information that is critical for the ....Dispersal and gene flow in habitat-forming algae. The temperate coast of Australia has a unique and diverse algal flora. Many of these algae play a central role in subtidal ecology by providing habitat to an astonishing diversity of taxa. Despite this, we have no understanding of levels of gene flow within and among populations of habitat forming algae or how such populations persist in nature. By addressing this lack of knowledge, my research will contribute information that is critical for the conservation and management of algal habitats. This is particularly pertinent because anthropogentic stressors are beginning to precipitate significant changes in algal forests along Australia's coastline. Read moreRead less
