Summary
The majority of Australian adults spend most of their waking hours sitting: at home, at work, and in their cars; most do not participate in exercise or sport. This leads to weight gain and to diseases of inactivity (particularly diabetes, heart disease, cancer and depression). New research will measure sitting time and the physical activity in people's daily lives, what factors encourage inactivity, and how to increase activity levels, especially among the ageing 'baby boomer' population.
The Evolution of Embodied Intelligence. The aim of the project is to write a collaborative monograph that integrates the recent development in cognitive science of alternatves to classical cognitivism with recent developments in evolutionary biology. Those developments include in particular the recognition of the importance both of non-genetic inheritence and of the role agents play in constructing their own environments. The monograph will argue that these evolutionary processes are of particul ....The Evolution of Embodied Intelligence. The aim of the project is to write a collaborative monograph that integrates the recent development in cognitive science of alternatves to classical cognitivism with recent developments in evolutionary biology. Those developments include in particular the recognition of the importance both of non-genetic inheritence and of the role agents play in constructing their own environments. The monograph will argue that these evolutionary processes are of particular importance in human evolution, and they are the key to explaining how it is that humans are simulataneously encultured beings and biological agents.Read moreRead less
Honeybee Navigation: Low-level and Cognitive Mechanisms. Anyone watching a honeybee find its way back home effortlessly after flying several kilometres in search of nectar would know that these insects are excellent navigators, despite their diminutive brains and relatively simple nervous systems. The aim of this proposal is to gain a better understanding of the mechanisms by which bees navigate repeatedly to an attractive food source, and recruit their nestmates to visit it. The findings should ....Honeybee Navigation: Low-level and Cognitive Mechanisms. Anyone watching a honeybee find its way back home effortlessly after flying several kilometres in search of nectar would know that these insects are excellent navigators, despite their diminutive brains and relatively simple nervous systems. The aim of this proposal is to gain a better understanding of the mechanisms by which bees navigate repeatedly to an attractive food source, and recruit their nestmates to visit it. The findings should illuminate important principles of animal navigation, as well as suggest novel strategies for robot navigation.Read moreRead less
To flee or not to flee: surviving on incomplete information. Even lowly animals, like the Australian fiddler crabs we will be investigating, are surprisingly competent in making the right decisions in complex situations. They actively acquire information and make good use of it to assure their immediate safety and their long term gains. Animals are exquisitely honed by evolution and we would benefit greatly by understanding what makes them so competent: on a theoretical level, we may learn about ....To flee or not to flee: surviving on incomplete information. Even lowly animals, like the Australian fiddler crabs we will be investigating, are surprisingly competent in making the right decisions in complex situations. They actively acquire information and make good use of it to assure their immediate safety and their long term gains. Animals are exquisitely honed by evolution and we would benefit greatly by understanding what makes them so competent: on a theoretical level, we may learn about efficient rules of good decision making and on a practical level, we may be able to design more flexible, robust and clever machines. Besides being useful in this wider context, the results of our research will thus also contribute to a new and 'sophisticated' appreciation of the cognitive design of animal.Read moreRead less
Honeybee Vision and navigation, and applications to robotics. Anyone observing a honeybee find its way home effortlessly after collecting nectar would know that these insects are excellent navigators, despite their diminutive brains and relatively simple nervous systems.

One aim of this proposal is to gain a better understanding of the mechanisms underling honeybee navigation. Another aim is to apply some of these findings to the development of novel, biologically inspired naviagtion systems for aircraft. The findings should illuminate important principles of animal navigation. They should also advance Australia's technology in the area of unmanned aerial vehicles (UAVs), which will have important applications in national defence and security.Read moreRead less
Biogeography of avian mating systems: polyandry, reverse-plumage dimorphism, and sexual selection in Cape York and New Guinea eclectus parrots. Current sexual selection theory explains how one sex can be strongly sexually selected through competition or mate choice, or how sexual selection can push both sexes in the same direction through mutual mate choice. However, the strong and independent sexual selection in both sexes of eclectus parrot is unique amongst birds, and poses a major challenge ....Biogeography of avian mating systems: polyandry, reverse-plumage dimorphism, and sexual selection in Cape York and New Guinea eclectus parrots. Current sexual selection theory explains how one sex can be strongly sexually selected through competition or mate choice, or how sexual selection can push both sexes in the same direction through mutual mate choice. However, the strong and independent sexual selection in both sexes of eclectus parrot is unique amongst birds, and poses a major challenge to existing theory. Here I propose novel field experiments and biogeographical comparisons of populations in Cape York and New Guinea that, when combined with molecular techniques and spectro-radiometry, will identify the elements of competition and mate choice responsible for their extraordinary reverse plumage dimorphism.Read moreRead less
Interspecific communication and the evolution of alarm calls in birds. There are probably more papers on vocal communication in some individual European and American species of birds than there are on all Australian species combined. Our work will contribute to redressing this imbalance by carrying out detailed studies on acoustic communication in a major group of Australian songbirds (scrubwrens, fairy-wrens, honeyeaters and allies), while at the same time addressing an unsolved general problem ....Interspecific communication and the evolution of alarm calls in birds. There are probably more papers on vocal communication in some individual European and American species of birds than there are on all Australian species combined. Our work will contribute to redressing this imbalance by carrying out detailed studies on acoustic communication in a major group of Australian songbirds (scrubwrens, fairy-wrens, honeyeaters and allies), while at the same time addressing an unsolved general problem in call design first identified 50 years ago in European songbirds. Specifically, we will test whether different prey species have repeatedly evolved 'hawk' alarm calls of similar structure, and whether such evolution could be due to benefits of having similar calls when communicating with other prey species.

Communication and predation in scrubwrens: alarm calls and eavesdropping. Animal behaviour, including acoustic communication, is shaped by the risk of being killed by predators. Many animals give alarm calls, potentially warning others of danger, and all face the risk that calls intended for conspecifics might be overheard by predators. We will use observations and playback experiments on birds to test what information is conveyed in alarm calls, and measure the risk of predators eavesdropping o ....Communication and predation in scrubwrens: alarm calls and eavesdropping. Animal behaviour, including acoustic communication, is shaped by the risk of being killed by predators. Many animals give alarm calls, potentially warning others of danger, and all face the risk that calls intended for conspecifics might be overheard by predators. We will use observations and playback experiments on birds to test what information is conveyed in alarm calls, and measure the risk of predators eavesdropping on the calls of young birds. Such work has never before been carried out on wild birds, and will contribute to the understanding of non-human communication about the environment and the design of signals.Read moreRead less
What is the genetic relationship between attractiveness, fighting ability and fertilization success in field crickets? The persistence of extravagant male sexual features like horns and bright colours remains a puzzle. There are many theoretical explanations but empirical tests are still rare. This study, which uses selective breeding, will provide insight into the genetic basis of male sexual attractiveness and dominance. Although focused on an endemic field cricket the potential results have w ....What is the genetic relationship between attractiveness, fighting ability and fertilization success in field crickets? The persistence of extravagant male sexual features like horns and bright colours remains a puzzle. There are many theoretical explanations but empirical tests are still rare. This study, which uses selective breeding, will provide insight into the genetic basis of male sexual attractiveness and dominance. Although focused on an endemic field cricket the potential results have wider implications. They may be applicable to many animals of importance to the community, including livestock, domesticated animals, pests and native wildlife. All these animals are subject to selection pressure created by humans. This study will help us understand how selection on one trait (e.g. weight) may influence the evolution of another (e.g. lifespan).Read moreRead less
The Evolution of the Social Brain: How Emotions and Moral Judgement Interact in the Generation of Cooperative Behaviour. Understanding the psychological forces that underpin human interactions is a necessary step to knowing how to improve those interactions.

Understanding the psychological forces that underpin human interactions is a necessary step to knowing how to improve those interactions. Comprehending the complex interplay of emotions and moral judgements lying behind decision-making in the social sphere will help explain such things as corruption, risk-taking, domestic violence, and political affiliation. Such knowledge can guide the design of effective social policy, and is vital for a realistic educational strategy. This project will strengthen Australia's excellent reputation in philosophy, bring here leading scholars from diverse fields, build international research networks, and in particular forge an ongoing partnership between the ANU and the California Institute of Technology.Read moreRead less
