Improving water quality modelling by better understanding solute transport. Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely ....Improving water quality modelling by better understanding solute transport. Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely collected in Australia's catchments and thereby better predict water quality behaviour. Proposed field studies aim to support this development. The outcomes sought are improved planning and management of water quality in our rivers, lakes and estuaries, improved health of these water bodies and improved water supplies.Read moreRead less
Why do only some exotics become invasive? Combining ecological and genomic approaches to address alternative hypotheses in a recent Australian weed. This project will specifically test alternative hypotheses about how weeds become invasive. As invasive weeds affect both agricultural and native ecosystems equally, research on understanding the mechanisms of weed invasion is critical. Outcomes will benefit Australia by allowing better prioritisation of management against exotic plants already i ....Why do only some exotics become invasive? Combining ecological and genomic approaches to address alternative hypotheses in a recent Australian weed. This project will specifically test alternative hypotheses about how weeds become invasive. As invasive weeds affect both agricultural and native ecosystems equally, research on understanding the mechanisms of weed invasion is critical. Outcomes will benefit Australia by allowing better prioritisation of management against exotic plants already in the country by providing predictive tools to estimate likelihood of spread. For formal Pest Risk Analysis by regulators (eg Biosecurity Australia), our project will provide genomic tools by which the potential weediness of a regulated plant can be assessed through genetic screening, and forms part of an international effort to identify 'weedy genes'.

The puzzle of Metazoan life history evolution: are feeding larvae always primitive? Most marine animals have a complex life-cycles with alternating pelagic larvae and benthic adults. An theory about animal life-history evolution states that feeding larvae are always primitive and larval feeding is lost but not gained. This hypothesis is based in part on studies on the 'classical' trochophore of marine worms such as Serpulidae, a group with both feeding and non-feeding larvae. We intend to establ ....The puzzle of Metazoan life history evolution: are feeding larvae always primitive? Most marine animals have a complex life-cycles with alternating pelagic larvae and benthic adults. An theory about animal life-history evolution states that feeding larvae are always primitive and larval feeding is lost but not gained. This hypothesis is based in part on studies on the 'classical' trochophore of marine worms such as Serpulidae, a group with both feeding and non-feeding larvae. We intend to establish a detailed phylogeny for Serpulidae and assess the evolution of larvae in the group. If feeding larvae are shown to be secondary this will raise doubts about established theories of animal evolution.Read moreRead less
Sharing values and the co-creation of brands: Towards a new consumer driven branding paradigm. The project proposes a paradigm shift from traditional image building towards a full understanding and integration of consumer values into a deliberate process of co-created brand meanings. Brands thus managed can become iconic and symbolic of consumers' existing subcultures or may even define micro-cultures of consumption of their own (as in the case of Harley Davidson).

The project proposes a paradigm shift from traditional image building towards a full understanding and integration of consumer values into a deliberate process of co-created brand meanings. Brands thus managed can become iconic and symbolic of consumers' existing subcultures or may even define micro-cultures of consumption of their own (as in the case of Harley Davidson).
Should managers understand the process by which such co-created brands develop, more Australian brand success stories (eg. Rip Curl, Penfold's Grange) would evolve and be better placed to tap the increasingly diversified sub-cultural landscape that characterises the Australian marketplace and many of our major trading partners.

The evolution of egg retention and sex allocation: a phylogenetic contrasts study using facultatively ovoviviparous thrips. Australian idolothripine thrips provide an unparalleled opportunity for investigating the evolution of reproduction. They constitute the only group to contain many species in which the females choose among live birth, egg laying or both. They also choose the sex of each offspring. We will use phylogenetics and experimentation to understand the evolutionary pressures that le ....The evolution of egg retention and sex allocation: a phylogenetic contrasts study using facultatively ovoviviparous thrips. Australian idolothripine thrips provide an unparalleled opportunity for investigating the evolution of reproduction. They constitute the only group to contain many species in which the females choose among live birth, egg laying or both. They also choose the sex of each offspring. We will use phylogenetics and experimentation to understand the evolutionary pressures that led to and maintain live birth and the allocation of sex. This will produce new insights into fundamental questions about the evolution of animal reproduction. Our collaborative approach will make Australian thrips and research an international cornerstone in the biology of reproductive evolution.Read moreRead less
Youth, religion and sexuality: digital media, school cultures, exemptions. This project aims to understand the knowledges and practices about sexuality and religion that form the everyday worlds of young people who are religious. This should provide significant new knowledge about a key time in the development of a young person’s identity via a nationwide, deep yet comparative approach. Expected outcomes include strategic health policy and curriculum development advice that responds to current d ....Youth, religion and sexuality: digital media, school cultures, exemptions. This project aims to understand the knowledges and practices about sexuality and religion that form the everyday worlds of young people who are religious. This should provide significant new knowledge about a key time in the development of a young person’s identity via a nationwide, deep yet comparative approach. Expected outcomes include strategic health policy and curriculum development advice that responds to current debates around religious exemptions to anti-discrimination law and creates better education and health care for religious and LGBTIQ+ youth. Benefits will include increased wellbeing for religious LGBTIQ+ youth, conservatively religious and newly arrived youth communities in Australia.Read moreRead less
Density regulation as a major determinant of population persistence: advancing empirical and theoretical approaches to conserve biodiversity. Without efficient application of limited conservation resources, more species will go extinct and invasive species will continue to proliferate. With a better understanding of extinction processes, a higher benefit:cost ratio will ensure better outcomes for biodiversity. We will directly address (1) the sustainable use of Australia's biodiversity by provid ....Density regulation as a major determinant of population persistence: advancing empirical and theoretical approaches to conserve biodiversity. Without efficient application of limited conservation resources, more species will go extinct and invasive species will continue to proliferate. With a better understanding of extinction processes, a higher benefit:cost ratio will ensure better outcomes for biodiversity. We will directly address (1) the sustainable use of Australia's biodiversity by providing evidence-based support for minimum viable population size targets to avoid extinction; (2) responding to climate change by determining the species- and environmentally specific contexts leading to elevated risks of extinction; and (3) protecting Australia from invasive diseases and pests by determining density targets that maximise eradication success.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
