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'.

Cell-free immune reactions and suppression. Insects pests and insect vectors of diseases are managed by toxic substances, but insects have a cunning ability to persist. How pesticide-tolerant insect pests recognise and inactivate chemical and biological toxins is poorly understood. While vertebrates with a closed circulatory system use coagulation reactions mainly for wound-healing, invertebrates employ cell-free aggregation reactions for the sequestration and inactivation of potentially damagin ....Cell-free immune reactions and suppression. Insects pests and insect vectors of diseases are managed by toxic substances, but insects have a cunning ability to persist. How pesticide-tolerant insect pests recognise and inactivate chemical and biological toxins is poorly understood. While vertebrates with a closed circulatory system use coagulation reactions mainly for wound-healing, invertebrates employ cell-free aggregation reactions for the sequestration and inactivation of potentially damaging objects and substances. We use insect plasma to dissect recognition and inactivation of damaging objects and substances with the aim to understand tolerance and its inhibition to design novel strategies in delaying tolerance to pesticides in insect pests.Read moreRead less
Addressing significant product safety knowledge gaps for older Australians . This project addresses significant gaps in contemporary knowledge of consumer product safety risks for older persons, with 25 years since the last Australian product safety research found older persons are at high risk of product-related injury/death. Products have evolved substantially and aged care models have changed in that time. This project generates contemporary knowledge of unsafe products causing injuries/death ....Addressing significant product safety knowledge gaps for older Australians . This project addresses significant gaps in contemporary knowledge of consumer product safety risks for older persons, with 25 years since the last Australian product safety research found older persons are at high risk of product-related injury/death. Products have evolved substantially and aged care models have changed in that time. This project generates contemporary knowledge of unsafe products causing injuries/deaths, risk factors/behaviours, and human rights issues. Outcomes benefiting the Australian community are improved prediction/characterisation of product safety issues for older Australians informing safer product design and use, targetted regulatory responses, ageing-in-place strategies, and creating safer home environments.Read moreRead less
The fundamental equations for inversion of operator pencils. This project seeks to deepen understanding of how complex systems may be significantly changed by incremental changes to ambient conditions. Mathematical models of complex systems (climate change processes, optimal driving strategies, efficient distribution policies, effective search routines) often depend on key parameters. If small perturbations to the parameters cause large changes to the solution, then the perturbations are said to ....The fundamental equations for inversion of operator pencils. This project seeks to deepen understanding of how complex systems may be significantly changed by incremental changes to ambient conditions. Mathematical models of complex systems (climate change processes, optimal driving strategies, efficient distribution policies, effective search routines) often depend on key parameters. If small perturbations to the parameters cause large changes to the solution, then the perturbations are said to be singular. This project aims to reveal the underlying mathematical structures and develop new computational algorithms to analyse a general class of perturbed systems both locally near an isolated singularity and globally. It plans to use these algorithms to solve systems of equations, calculate generalised inverse operators, examine perturbed Markov processes, and estimate exit times from meta-stable states in stochastic population dynamics.Read moreRead less
Evaluating consumer product regulatory responses to improve child safety. This project aims to quantify the level of similarity between consumer product regulatory practices and child injuries, and compare national approaches. Consumer product safety regulation operates in a global and ‘virtual’ market. Online purchasing, limited border protection and distance between suppliers and consumers make monitoring and enforcing product safety more difficult for regulators, putting consumers at risk. A ....Evaluating consumer product regulatory responses to improve child safety. This project aims to quantify the level of similarity between consumer product regulatory practices and child injuries, and compare national approaches. Consumer product safety regulation operates in a global and ‘virtual’ market. Online purchasing, limited border protection and distance between suppliers and consumers make monitoring and enforcing product safety more difficult for regulators, putting consumers at risk. A rapid responsive product safety system that operates across sectors and borders is an international priority. This project expects to close gaps in consumer regulatory practice and safety policy.Read moreRead less
