Summary
Biological adaptation under natural and anthropogenic conditions. This project covers all four national priority areas. Nature abounds with conflicts between what is good for the individual or a larger entity (a population, a society, or a species). Researching them will explain why populations adapt or fail to adapt to novel conditions (e.g., climate change) and predict when interventions are beneficial. Similar rules govern the spread of invasive species. Even health problems, e.g., new virule ....Biological adaptation under natural and anthropogenic conditions. This project covers all four national priority areas. Nature abounds with conflicts between what is good for the individual or a larger entity (a population, a society, or a species). Researching them will explain why populations adapt or fail to adapt to novel conditions (e.g., climate change) and predict when interventions are beneficial. Similar rules govern the spread of invasive species. Even health problems, e.g., new virulent strains of human, animal or plant diseases, require such evolutionary thinking. Cutting-edge mathematical tools also prepare Australians for an era in the near future where genomic data are so cheap to acquire that training in complex mathematical and logical analysis becomes a factor limiting scientific progress.Read moreRead less
Retracing the Early Evolution of Metazoa using Novel Methods and Strategies. Metazoa is one of the best-characterised groups of species in terms of its morphology, fossil record, development, and genetic make-up, but the phylogeny remains obscure because the fossil record is incomplete and because molecular phylogenetic methods have not yet been developed with the complexity of genomic data in mind. We will develop methods and strategies for the analysis of whole genomes, and use them in studies ....Retracing the Early Evolution of Metazoa using Novel Methods and Strategies. Metazoa is one of the best-characterised groups of species in terms of its morphology, fossil record, development, and genetic make-up, but the phylogeny remains obscure because the fossil record is incomplete and because molecular phylogenetic methods have not yet been developed with the complexity of genomic data in mind. We will develop methods and strategies for the analysis of whole genomes, and use them in studies of the mitochondrial genome. We will infer the animal phylogeny, and use it to chart the evolution of animal morphology and development, and the evolution of mitochondrial genetic codes, gene order, and nucleotide content.Read moreRead less
A new universal mechanism controlling body proportions in animals. This project aims to establish that a recently-discovered mechanism, the inhibitory cascade, determines the basic proportions of appendages and body segments in a diverse range of animal groups, particularly vertebrates and arthropods. The goals of the project are to reveal the molecular mechanisms in mice and insects, and build computer simulations to show how to manipulate the control of development by the inhibitory cascade. T ....A new universal mechanism controlling body proportions in animals. This project aims to establish that a recently-discovered mechanism, the inhibitory cascade, determines the basic proportions of appendages and body segments in a diverse range of animal groups, particularly vertebrates and arthropods. The goals of the project are to reveal the molecular mechanisms in mice and insects, and build computer simulations to show how to manipulate the control of development by the inhibitory cascade. The project should benefit bioengineering by establishing control mechanisms for the manipulation and regeneration of teeth and limbs.Read moreRead less
House hunting honey bees: speed-accuracy trade-offs in collective decision-making. This project will uncover the mechanisms that underlie the trade-off between speed and accuracy in collective decision-making. We will study two species of honey bee that differ in the relative importance of speed and accuracy when deciding on a new home. Natural selection has shaped the decision-making process differently in the two species, one favouring speed, the other accuracy. We will use the natural wisdom ....House hunting honey bees: speed-accuracy trade-offs in collective decision-making. This project will uncover the mechanisms that underlie the trade-off between speed and accuracy in collective decision-making. We will study two species of honey bee that differ in the relative importance of speed and accuracy when deciding on a new home. Natural selection has shaped the decision-making process differently in the two species, one favouring speed, the other accuracy. We will use the natural wisdom evolved by the bees to design new mathematical models of collective decision-making. These can be applied to create efficient decision-making tools that will be useful for any large organization.Read moreRead less
Social insect behaviour: the importance of individual-decision making and information transfer. Insect societies are complex systems. Understanding complex systems is often hampered by our inability to study the individual units that comprise the system without also disturbing the system. Insect societies are unique in that the individual insects can be studied within their natural setting. This project will study foraging behaviour of honey bees with respect to individual decision-making and in ....Social insect behaviour: the importance of individual-decision making and information transfer. Insect societies are complex systems. Understanding complex systems is often hampered by our inability to study the individual units that comprise the system without also disturbing the system. Insect societies are unique in that the individual insects can be studied within their natural setting. This project will study foraging behaviour of honey bees with respect to individual decision-making and information transfer. In doing so we will obtain insights in the working of other, less accessible, complex systems such as the mammalian brain or the Australian economy.Read moreRead less
