This project aims to investigate whether artificial light at night drives evolutionary change using a combination of field observations, laboratory experiments and advanced genetic techniques. This multi-disciplinary study expects to provide a significant advance in understanding of the impact of light at night for animals and will enhance our capacity to predict the outcome of future urban expansions for all species. The outcomes will have broad implications for estimating the future biodiversity and health of our urban areas and will benefit both globally and within Australia by providing much needed data regarding the likely resilience of species currently residing in our major cities.Read moreRead less
Quantifying environmental constraints on animal behaviour. This project aims to determine how habitat structure, weather and motion vision influence animal behaviour. Motion vision controls locomotion, foraging, evading predators and communicating. However, information on the conditions for motion vision in natural environments is limited. To address this, this project will combine field techniques with tools from 3D animation and computer vision. The project will focus on Australia’s dragon liz ....Quantifying environmental constraints on animal behaviour. This project aims to determine how habitat structure, weather and motion vision influence animal behaviour. Motion vision controls locomotion, foraging, evading predators and communicating. However, information on the conditions for motion vision in natural environments is limited. To address this, this project will combine field techniques with tools from 3D animation and computer vision. The project will focus on Australia’s dragon lizards, and place their motion displays in a visual-ecological context. The expected outcome is a more complete picture of the signalling context, which could advance sensory ecology, vision science and animal behaviour, with practical applications in artificial intelligence and derived benefits for education and community engagement in biology.Read moreRead less
Understanding How the Hungry Brain Regulates Metabolism. Energy homeostasis is essential for life as it ensures an adequate supply of fuel to cells of the body. This process is orchestrated by neurons in the hypothalamus of the brain. This project aims to determine the role of the extracellular matrix that surrounds hypothalamic neurons and how this regulates energy homeostasis, an area of science that is completely unexplored. This project expects to identify the composition the extracellular m ....Understanding How the Hungry Brain Regulates Metabolism. Energy homeostasis is essential for life as it ensures an adequate supply of fuel to cells of the body. This process is orchestrated by neurons in the hypothalamus of the brain. This project aims to determine the role of the extracellular matrix that surrounds hypothalamic neurons and how this regulates energy homeostasis, an area of science that is completely unexplored. This project expects to identify the composition the extracellular matrix within the hypothalamus and discover how it regulates energy homeostasis. The outcomes of this project are to provide new knowledge in understanding how the brain regulates metabolism, to promote population health & wellbeing, develop new technologies and training the next generation of researchers.Read moreRead less
Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as pred ....Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as predator cues, enhance avoidance behaviour. This project will uncover the neural circuitry and endocrine mechanisms through which hunger influences hypothalamic threat-detecting circuits that suppress food intake. These studies provide a new hypothalamic model to understand risk/reward decision in the brain.Read moreRead less
Avian embryonic perception: what role for good vibrations? It has long been recognised that animals perceive environmental information before they are born. This project will test for the first time whether such avian communication systems rely on vibrations. We will test the hypothesis that cryptic communication using rhythmic vibration, is essential for embryonic birds to sense parental cues regarding rising temperatures, by measuring neural control in adults, as well as embryonic perception a ....Avian embryonic perception: what role for good vibrations? It has long been recognised that animals perceive environmental information before they are born. This project will test for the first time whether such avian communication systems rely on vibrations. We will test the hypothesis that cryptic communication using rhythmic vibration, is essential for embryonic birds to sense parental cues regarding rising temperatures, by measuring neural control in adults, as well as embryonic perception and response. By experimentally manipulating family communication we will demonstrate the potential for prenatal vibrations to alter developmental outcomes, enriching our understanding of avian sensory development.These data are important for the commercial poultry industry and for captive breeding programs.

Our senses perceive the outside world and permit appropriate behaviours, but the underlying brain circuits are poorly understood. This project will use new technologies to observe all active brain cells in zebrafish during the important behaviour of visual predator avoidance and characterise the underlying circuits comprehensively. This approach's significance is in its breadth, spanning functional imaging, anatomy, computational modelling, and behaviour, with the major outcome of producing the first complete map of a visual behaviour at the level of brain circuits and the individual brain cells composing them. Benefits will include new insights into visual processing and the refinement of new genetic, optical, and informatics approaches.Read moreRead less
Self-organised communication as a foundation of large, complex societies. This Project aims to investigate how evolution has shaped the self-organisation of robust communication networks that emerge in large animal collectives from the actions of individuals following only simple, local rules.

This Project aims to investigate how evolution has shaped the self-organisation of robust communication networks that emerge in large animal collectives from the actions of individuals following only simple, local rules. It expects to generate new knowledge into the fundamental principles guiding the self-organisation of networks that can sustain a complex society. Empirical work with ant colonies will inform the construction of simulation models to push the investigation beyond experimental limits. The Project should significantly advance our understanding of how communication networks enable the development of large societies, and thus of how to better manage autonomous man-made networks, most importantly the Internet-of-Things.Read moreRead less
