Understanding the crowd - improving accuracy in collective motion theory. This project intends to develop more accurate methods for predicting the motions of large groups. The amazing coordinated movements seen in large groups of animals are governed by simple interactions between individuals, termed rules of motion. In 2011, techniques were developed to estimate individual rules of motion from video tracking data. The project plans to build on these breakthroughs by using advanced tracking, mod ....Understanding the crowd - improving accuracy in collective motion theory. This project intends to develop more accurate methods for predicting the motions of large groups. The amazing coordinated movements seen in large groups of animals are governed by simple interactions between individuals, termed rules of motion. In 2011, techniques were developed to estimate individual rules of motion from video tracking data. The project plans to build on these breakthroughs by using advanced tracking, modelling and analysis to systematically determine the influence that different movement parameters have on rules of motion and how rules of motion are affected by group size. It aims to develop a framework for analysis and modelling built on the visual perception of individuals.Read moreRead less
Leadership matters: the emergence of informed leaders and their influence on group movement. This project will discover the effect of leadership and social structure on collective motion in schools of damselfish, swarms of honey bees and human pedestrians using videoed experiments and computer simulations. These findings will be important in preventing crowd stampedes, understanding risky road crossing behaviour and designing 'swarms' of robots.

Summary
Animal groups as mobile sensor networks. This project aims to provide biologically inspired solutions to the problems faced by mobile sensor networks. Mobile sensor networks provide a powerful new tool in environmental monitoring and surveillance, however, designing them to be energy efficient while not sacrificing information detection remains a challenge. By immersing animal groups into dynamically changing virtual environments this project will design new efficient mobile sensor networks. The ....Animal groups as mobile sensor networks. This project aims to provide biologically inspired solutions to the problems faced by mobile sensor networks. Mobile sensor networks provide a powerful new tool in environmental monitoring and surveillance, however, designing them to be energy efficient while not sacrificing information detection remains a challenge. By immersing animal groups into dynamically changing virtual environments this project will design new efficient mobile sensor networks. The project is expected to provide solutions to mobile sensor network limitations, benefitting areas including robotics, environmental monitoring and defence.Read moreRead less
From individuals to mass organisation: aggregation, synchronisation and collective movement in locusts. By combining field biology, robotics and mathematics, this project will determine how animals flock or swarm and, in particular, how locust nymphs control their collective movement over their lifetime. The mathematical models derived during the project will be directly applied to controlling outbreaks of locusts in Australia, South and North Africa.
The evolutionary biology of seminal fluid. This project will identify proteins within seminal fluid that impact sperm performance and male fertility. The work will derive new insights into the evolution of seminal fluid proteins, while simultaneously exploring how environmental factors such as diet impact male fertility in animals and humans.

One genome but two sexes: Conflict and the evolution of sexual dimorphism. How can males and females display striking sex differences, when they primarily share the same set of genes? By experimentally evolving the degree of sexual dimorphism in Drosophila melanogaster, this project endeavours to address key issues at the heart of evolutionary biology. This project aims to deliver a novel, data-rich resource with which to explore the mechanisms and consequences of sexual dimorphism evolution, to ....One genome but two sexes: Conflict and the evolution of sexual dimorphism.

By experimentally evolving the degree of sexual dimorphism in Drosophila melanogaster, this project endeavours to address key issues at the heart of evolutionary biology. This project aims to deliver a novel, data-rich resource with which to explore the mechanisms and consequences of sexual dimorphism evolution, to expand current understanding of this fundamental evolutionary paradox.Read moreRead less
The oxygen paradox and the evolution of sex differences. Free radicals are reactive molecules linked to the onset of ageing, cancers and infertility. By advancing an emerging paradigm that contends that 'free radicals' are important drivers of evolutionary change, this project will lead the field and provide an excellent platform on which to train students to the highest standards.

Unifying cornerstones of social evolution: theory and application. This proposal aims to reconcile and unify alternative methods in social evolution theory, one of the foundations of our modern understanding of evolutionary and behavioural ecology. Social evolution has been controversial, but recent years have seen major developments. By combining mathematical models and empirical data, this project expects to end the controversies by removing boundaries between theoretical approaches. Specific ....Unifying cornerstones of social evolution: theory and application. This proposal aims to reconcile and unify alternative methods in social evolution theory, one of the foundations of our modern understanding of evolutionary and behavioural ecology. Social evolution has been controversial, but recent years have seen major developments. By combining mathematical models and empirical data, this project expects to end the controversies by removing boundaries between theoretical approaches. Specific applications of theory include social insect evolution, individuality and selection in plants. Unification of theory is expected to enhance research capacity in Australia and internationally.Read moreRead less
Adaptive function of insect cuticular lipids. Insects secrete onto their surface a cocktail of high melting-point waxes. These biological compounds have been found to be involved in communication but are also thought to protect the insect from water loss and pathogen invasion. Insects represent the most abundant group of animals on Earth. It has been suggested that the dual role of surface waxes in ecological adaptation and reproduction may be key to their remarkable divergence. However, little ....Adaptive function of insect cuticular lipids. Insects secrete onto their surface a cocktail of high melting-point waxes. These biological compounds have been found to be involved in communication but are also thought to protect the insect from water loss and pathogen invasion. Insects represent the most abundant group of animals on Earth. It has been suggested that the dual role of surface waxes in ecological adaptation and reproduction may be key to their remarkable divergence. However, little is known of the function of individual compounds within mixtures of insect waxes. Using chemical analysis, neurophysiology and whole animal performance, the aim of this project is to provide a detailed understanding of the function of insect surface wax with potential for bioinspired products.Read moreRead less

Ecophysiology and evolution of sleep and adaptive sleeplessness. The function of sleep is enigmatic, even though the treatment of costly sleep disorders requires an understanding of the function that sleep performs. This project approaches this enigma with the comprehensive study of sleep in diverse animals to examine ecological-induced plasticity and evolution of sleep.

The function of sleep is enigmatic, even though the treatment of costly sleep disorders requires an understanding of the function that sleep performs. This project approaches this enigma with the comprehensive study of sleep in diverse animals to examine ecological-induced plasticity and evolution of sleep. Using innovative technologies in real-world situations, this project will spearhead the study of sleep ecophysiology to identify animals that are resilient to the negative effects of sleep loss, and will determine whether the evolution of new types of animal was associated with the co-evolution of new types of sleep. The outcomes will have wide-ranging implications for our view of sleep function, prescriptions for an optimal amount of sleep and human health and wellbeing.Read moreRead less
