Evolution, learning, and the use of multiple cues in desert ant navigation. 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.

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
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.
Information processing at its limits: from the dimmest habitats to the smallest sizes. Ensuring optimal information processing at the limits of size and ambient light is a challenge for technical systems, but has been elegantly solved by animals. The challenge of navigation is similar for animals of all sizes and in both day and night. This project aims to conduct a comparative analysis to identify the consequence of size and light on the information processing capacities for visual navigation. ....Information processing at its limits: from the dimmest habitats to the smallest sizes. Ensuring optimal information processing at the limits of size and ambient light is a challenge for technical systems, but has been elegantly solved by animals. The challenge of navigation is similar for animals of all sizes and in both day and night. This project aims to conduct a comparative analysis to identify the consequence of size and light on the information processing capacities for visual navigation. Outcomes of this project will reveal the behavioural and physiological adaptations needed and the costs associated with navigating in the dimmest of habitats and at the smallest of sizes. Identifying such optimal biological solutions for robust navigation will be relevant for image processing, computer vision and robotics.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
Brain lateralization: its function, evolution, development and change with ageing. Brain research is undoubtedly one of the key research fields today. This project involves highly innovative research at the highest international level, keeping Australia at the forefront of research on brain lateralization, a very important field of brain research in humans and animals (co-founded by the applicant). This project 1) investigates dynamic changes of the developing, mature and ageing brain for vital ....Brain lateralization: its function, evolution, development and change with ageing. Brain research is undoubtedly one of the key research fields today. This project involves highly innovative research at the highest international level, keeping Australia at the forefront of research on brain lateralization, a very important field of brain research in humans and animals (co-founded by the applicant). This project 1) investigates dynamic changes of the developing, mature and ageing brain for vital functions using animal models, thus contributing importantly to our understanding of normal functions of the human brain, including some forms of mental dysfunction and also ageing; 2) trains postgraduate students at the highest standards and 3) maintains important collaboration with colleagues in Europe.

Higher cognition and hemispheric specialization in an avian species: referential and intentional communication. We will discover whether alarm calls of Australian magpies, noted for their outstanding range of vocalisations, are referential (signalling predator type and location) and intentional (vocalised in specific contexts). Such complex communication , once thought to be unique to humans, has been found in some mammals and just one avian species, the domestic chick. This project will be the ....Higher cognition and hemispheric specialization in an avian species: referential and intentional communication. We will discover whether alarm calls of Australian magpies, noted for their outstanding range of vocalisations, are referential (signalling predator type and location) and intentional (vocalised in specific contexts). Such complex communication , once thought to be unique to humans, has been found in some mammals and just one avian species, the domestic chick. This project will be the first such investigation of an avian species in its natural habitat. This is important also because bird and mammalian brains are organised differently and birds offer a unique opportunity to discover whether one hemisphere is specialised for this purpose.Read moreRead less

Building your future: builder-building coevolution in animal architectures. This project aims to reconstruct how animal architectures change throughout time and how this affects body shapes and functions of their builders. By clarifying the biological role of building behaviour this project will assist in predicting long term responses of wildlife, ecosystems and human life to a changing environment.

This project aims to reconstruct how animal architectures change throughout time and how this affects body shapes and functions of their builders. By clarifying the biological role of building behaviour this project will assist in predicting long term responses of wildlife, ecosystems and human life to a changing environment. The project expects to be achieved by comparing the structure, assembly and mechanical performance of animal architectures with animal morphology and performance in a global phylogenetic framework. This is critical for strategic planning of wildlife and landscape management.Read moreRead less
