This research on desert ants benefits Australia by fostering an international collaboration with one of the best European scientists, training students, and increasing knowledge about Australia's unique fauna, helping us to appreciate and better manage our fragile desert environments. With this international link, students working on this and related projects benefit intellectually from mingling with an international community of scientists.Understanding insect behaviour also has benefits for robotics. Work on desert ants has already resulted in robotic applications, and our outcomes concerning the optimal integration of multiple spatial cues are especially relevant.Read moreRead less
Towards a behavioural ecology of navigational memories in desert ants. Navigational memories (path integration, systematic search, and landmark use) in a Central Australian desert ant (Melophorus bagoti) and a North African desert ant (Cataglyphis fortis) are studied at the ants? natural habitats. The project tests predictions about behavioural properties of memory (how quickly it can be acquired, how long it lasts, and how a conflicting event affects it), based on a cost-benefit analysis of the ....Towards a behavioural ecology of navigational memories in desert ants. Navigational memories (path integration, systematic search, and landmark use) in a Central Australian desert ant (Melophorus bagoti) and a North African desert ant (Cataglyphis fortis) are studied at the ants? natural habitats. The project tests predictions about behavioural properties of memory (how quickly it can be acquired, how long it lasts, and how a conflicting event affects it), based on a cost-benefit analysis of the functions of each memory system. The project launches the first systematic cost-benefit analysis of memory, to establish a behavioural ecology of memory. We hope that it inspires cost-benefit analyses of other functions of the brain.Read moreRead less
What is the biological significance of electrosensitivity in crayfish? The finding that an Australian crayfish responds to low-level electrical signals in the surrounding water is the first report of electrosensitivity in an aquatic invertebrate. This project will investigate its unknown biological significance. The results will impact on behavioural studies in all aquatic invertebrates because they will now have to consider this factor. Some other decapod crustaceans will almost certainly be fo ....What is the biological significance of electrosensitivity in crayfish? The finding that an Australian crayfish responds to low-level electrical signals in the surrounding water is the first report of electrosensitivity in an aquatic invertebrate. This project will investigate its unknown biological significance. The results will impact on behavioural studies in all aquatic invertebrates because they will now have to consider this factor. Some other decapod crustaceans will almost certainly be found to be electrosensitive. Not only are these important subjects for behavioural analysis, many form the basis of important commercial aquaculture industries. The outcomes will enhance Australia's scientific standing and provide opportunities for students to become leaders in a new field. 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
On the move: the study of self-organised movement of animal groups with and without leadership. This project will uncover the common principles that control the movement of large groups of organisms. We will focus on swarming honey bees, hopping bands of billions of locusts and millions of crickets marching in unison. The outcomes of our research will be broadly applicable to other collective phenomena, even to traffic and crowd control in humans.
Visual processing of objects defined by coherent motion. Although the human brain can easily decode the complex visual scene, little is known about how the responsible neural circuits operate. For example, how is it that a camouflaged animal, such as a moth on the bark of a tree, becomes visible once it moves? To better understand the processes, this project aims to determine how different visual areas of the brain interact with each other to create a network that is responsible for detecting ....Visual processing of objects defined by coherent motion.

To better understand the processes, this project aims to determine how different visual areas of the brain interact with each other to create a network that is responsible for detecting moving camouflaged objects. Knowing this will enable us to better understand the organisation and limitations of the brain.Read moreRead less
Understanding social cancers: Intra-specific parasitism by honeybee workers. Our project will study the conditions under which normally altruistic honeybee workers parasitise other colonies. Thus we will explore a fundamental question: how is the expression of selfish behaviour normally controlled? Outcomes of this project will be important to our understanding of insect societies but will also have application for those studying the development of tumours in multicellular organisms, the develop ....Understanding social cancers: Intra-specific parasitism by honeybee workers. Our project will study the conditions under which normally altruistic honeybee workers parasitise other colonies. Thus we will explore a fundamental question: how is the expression of selfish behaviour normally controlled? Outcomes of this project will be important to our understanding of insect societies but will also have application for those studying the development of tumours in multicellular organisms, the development of metazoan bodies, and social cohesion in human and non-human societies. Our project will also help protect Australia's honey industry from the devastating social parasites that have ruined the industry in South Africa.Read moreRead less
The entrainment of circadian rhythms in marsupial mammals: behavioural and sub-cellular investigation of non-rod, non-cone ocular photoreceptors. Our investigation will provide a contribution to understanding the role that photoreceptors play in the mechanisms that control circadian rhythms and will ultimately lead to a better understanding of the basic physiology of sleep and circadian cycles, their contribution to learning and memory and their impact on waking performance. Targeted drug develo ....The entrainment of circadian rhythms in marsupial mammals: behavioural and sub-cellular investigation of non-rod, non-cone ocular photoreceptors. Our investigation will provide a contribution to understanding the role that photoreceptors play in the mechanisms that control circadian rhythms and will ultimately lead to a better understanding of the basic physiology of sleep and circadian cycles, their contribution to learning and memory and their impact on waking performance. Targeted drug development and the design of lighting systems effective in regulating circadian rhythms will improve the quality of life and competitiveness of the many citizens who endure abnormal sleep/wakefulness schedules.Read moreRead less
