How are visual gene pathways lost and restored during reptile evolution? This project aims to investigate how complex traits are lost during evolution, and once lost if they can be regained. The project will use the diverse visual systems of snakes and lizards to shed light on the process of gene loss in degenerative lineages, and discover the mechanisms that compensate for gene losses in taxa with secondarily evolved visual capabilities- providing a case of evolutionary re-innovation in complex ....How are visual gene pathways lost and restored during reptile evolution?

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
Evolving with sexually transmitted infections. This project aims to understand how sexually transmitted infections (STIs) affect the evolution of host mating systems. STIs threaten the health of most sexually-reproducing organisms. In evolutionary terms, their mode of transmission imposes distinct selection patterns on hosts.

This project aims to understand how sexually transmitted infections (STIs) affect the evolution of host mating systems. STIs threaten the health of most sexually-reproducing organisms. In evolutionary terms, their mode of transmission imposes distinct selection patterns on hosts. This project will use an Australian beetle and its sexually transmitted mite to investigate how STIs lead to evolutionary changes in host mating behaviour and explore the genetic basis for STI resistance. This project is expected to affect the evolution of host mating biology and lead to sex-specific optimal levels of disease resistance, which can influence disease dynamics and host-disease coevolution.Read moreRead less
Mechanisms of colour production and the evolution of animal signals. This project aims to reveal how diverse colours are produced in reptiles and the information these colours convey about individual health, condition and performance. The project evaluates how stress affects both pigment deposition and the nano-structure of cells and tissues, which together produce colour. By comparing similar colours generated by two entirely different classes of pigment (carotenoids and pteridines), this proje ....Mechanisms of colour production and the evolution of animal signals. This project aims to reveal how diverse colours are produced in reptiles and the information these colours convey about individual health, condition and performance. The project evaluates how stress affects both pigment deposition and the nano-structure of cells and tissues, which together produce colour. By comparing similar colours generated by two entirely different classes of pigment (carotenoids and pteridines), this project will provide new insights into the evolution of animal coloration, and will significantly enhance our understanding of pteridines, one of the most prevalent but least understood classes of pigment in vertebrates.Read moreRead less

Unravelling the molecular diversity and evolution of centipede venoms. The project intends to improve understanding of venom evolution in centipedes. Venoms have emerged as a rich source of pharmacological tools with potential for development into therapeutics and bioinsecticides. However, venoms-based discovery has been limited by the narrow taxonomical range of animals studied, with many groups of venomous animals overlooked. One such group is centipedes, whose venoms contain diverse toxins th ....Unravelling the molecular diversity and evolution of centipede venoms. The project intends to improve understanding of venom evolution in centipedes. Venoms have emerged as a rich source of pharmacological tools with potential for development into therapeutics and bioinsecticides. However, venoms-based discovery has been limited by the narrow taxonomical range of animals studied, with many groups of venomous animals overlooked. One such group is centipedes, whose venoms contain diverse toxins that differ between taxa. This project aims to provide an insight into centipede venom evolution, and how it might be constrained by venom-gland morphology. This study seeks to contribute to our understanding of protein evolution and direct biodiscovery efforts around centipede venom.Read moreRead less

This project aims to investigate mechanisms underlying animal adaptation to future environmental change by examining the molecular basis for phenotypic plasticity in snakes. This project will specifically examine variation in genetic/epigenetic profiles and compare against important fitness traits, such as variable head size, bite force and swallowing performance to identify relationships between molecular change and physiology. Such research is a critical first step in improving our knowledge of the mechanisms whereby animal populations may adapt to environmental change, allowing us to facilitate such processes or concentrate conservation effort where species are unable to adapt via epigenetic modification.Read moreRead less

Summary
The uptake of best practice approaches in fisheries and aquaculture is influenced by factors that inhibit or enable behaviour change, including psycho-sociological factors (i.e. how change or approaches are framed). Previous FRDC research has indicated a need to identify how and where behavioural insights/interventions – which draw on psycho-sociological factors such as cognitive biases, social norms, and emotions – can be used to steer behaviour change towards preferred outcomes (e.g. stewa ....The uptake of best practice approaches in fisheries and aquaculture is influenced by factors that inhibit or enable behaviour change, including psycho-sociological factors (i.e. how change or approaches are framed). Previous FRDC research has indicated a need to identify how and where behavioural insights/interventions – which draw on psycho-sociological factors such as cognitive biases, social norms, and emotions – can be used to steer behaviour change towards preferred outcomes (e.g. stewardship, safety) in marine sectors. This project builds on current and emerging research on behaviour change in fisheries and aquaculture to consolidate a review of published literature and available grey literature and R&D (from academic and industry domains, including recent FRDC projects relating to behaviour change) that has identified psycho-sociological factors influencing behavioural change. The aim of this literature review is to identify the types of behavioural interventions that can (or potentially, cannot) achieve preferred outcomes for fishing and aquaculture sectors in Australia. Specifically, the review seeks to explore i) which kinds of behavioural interventions can be effective in achieving positive change, ii) where (and just as importantly, where not) these interventions may be applied in fisheries and aquaculture sectors, iii) identify (potential) limitations of interventions, and to iii) bring these findings together to inform and underpin development of two relevant and engaging training webinars and associated resource materials, and iv) make recommendations for further focused trials/intervention research which could be undertaken to further support and expedite desired outcomes in Australian fisheries and aquaculture.
There is rapidly growing interest in the development, application and evaluation of behavioural interventions and they show great potential, however, they are also complex to design, test, and implement. Individuals are more likely to change their behaviours if they have the necessary skills and perceive they can do so (capability), if their environment (physical as well as social) provides an opportunity to do so (opportunity), and if they are motivated to achieve a particular endpoint through this behaviour (motivation), either through conscious decision-making or automatic processes, such as momentary cues. Further, the use of behavioural interventions has not been without critique, with concerns about ethics, manipulation, or risk to human agency. There are also concerns about the effectiveness of behavioural interventions, which may derive from several reasons: for example, due to misunderstanding the behaviour that is intended to be changed and the expected response by the audience. A behavioural intervention will be ineffective if the messaging or delivery causes confusion or if it only has a short-term effect. Some interventions can cause unintended consequences or compensating behaviours resulting in no net effect. These reasons highlight the importance of appropriate contextual understanding and well-defined outcomes for the design of effective behavioural interventions.
There are also different avenues for intervention beyond cognitive biases: education, persuasion, incentivisation, coercion, training, restriction, environmental restructuring, modelling and enablement, and the framing and implementation of these can differ depending on who the intervention is targeted at and under what context. Targeting behaviours in fisheries and aquaculture may enhance engagement and sustainable changes in the longer term (e.g. via development of new social norms), but to achieve this, changes in the determinants of behaviour are required. Actions (e.g. citizen science projects, local management practices), feelings, values (e.g. connectedness to oceans, the realisation of links between ocean health and human health) and social norms are embedded in and influenced by, local environments and social spheres that can transcend geographical boundaries. Our project will explore these nuances and convey concise summaries of behaviour change interventions for end-users via webinars, fact sheets, a simple decision tree tool (described below) and several short videos. The project intentionally has a broad focus (across fisheries and aquaculture sectors) in its review and outputs, as it is designed to equip potential developers and implementers of behavioural interventions with the skills and knowledge to do so in their own unique context. However, we will engage with industry partners (including FRDC extension officers and the industry advisory groups) to specifically ensure that the knowledge and tools produced (i.e. extension products) will be accessible and adaptable to the diversity of relevant contexts across these sectors - and useful for end-users seeking to motivate behaviour change whilst still retaining industry trust and engagement.
The project brings together necessary interdisciplinary research expertise (details outlined below) in the fields of behavioural economics, resource and fisheries economics, socio-ecology, fisheries ecology, science communication and cognitive psychology. In addition, the transdisciplinary potential of this project will be achieved via collaboration with a research advisory panel (to ensure rigorous research outcomes) and an industry level advisory panel (to ensure that the results and suggested interventions/activities are fit-for-purpose and accessible to the sector). Working with these panels (which would ideally include FRDC partners), we will ensure that the research is co-designed – and thus, project outputs are fit-for-purpose/context. Our team’s existing collective research on adoption and uptake of interventions clearly shows that engaging and involving end-user at creation stages increases uptake of results – hence, the value of our industry advisory panel. In addition, by engaging with industry leaders, we will create industry champions for the project who may assist with the dissemination of outputs. Together, the advisory groups will help to further define/adapt the scope of the project to achieve impact.
Overall, these collaborations and contributions will ensure that this project will deliver a comprehensive and industry-relevant overview of current understanding of behaviour change interventions, that addresses end-users’ identified needs, and that inspires community trust, in formats that are palatable and accessible to them and the fisheries and aquaculture sectors more broadly.. Objectives: 1. Conduct a systematic review of behavioural interventions for positive outcomes in the fisheries and aquaculture sectors. 2. Develop a two-part webinar series targeted at the FRDC community that aims to provide accessible and implementable knowledge on the theory and practice of behavioural interventions in fisheries. 3. Provide open-access knowledge about behavioural interventions with/to stakeholders via supporting materials (including a decision tree tool), fact-sheets, visual aids, and video. 4. Identify areas for future focused work and interventions that can be implemented to support the fisheries and aquaculture sectors Read moreRead less
