Understanding animals through their movement. This project aims to develop a suite of analytical methods to understand animals' behaviour through their movement patterns. Animal movement patterns encode detailed information about their behavioural state. Collecting and analysing animal movement trajectories can provide us with completely new insights to behaviour. Recent developments in bio-logging technologies have provided an incredible amount of rich data on free-ranging animals. This project ....Understanding animals through their movement. This project aims to develop a suite of analytical methods to understand animals' behaviour through their movement patterns. Animal movement patterns encode detailed information about their behavioural state. Collecting and analysing animal movement trajectories can provide us with completely new insights to behaviour. Recent developments in bio-logging technologies have provided an incredible amount of rich data on free-ranging animals. This project will develop a suite of analytical techniques to interrogate this data through a combination of approaches, from fine scale experiments in the laboratory to tracking animal trajectories from the International Space Station. The findings will deliver major benefits to the broader community by transforming our ability to manage and conserve animal stocks.Read moreRead less
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.
A complex systems approach to preventing colony failure in honey bees. This project aims to use complex systems science to detect and prevent colony collapse in honey bees while advancing knowledge of tipping points in complex social systems. Understanding the mathematics of colony collapse can help us develop strategies for safeguarding managed bee populations and the valuable pollination services they provide. Expected outcomes include methods for the early detection of stress in colonies, met ....A complex systems approach to preventing colony failure in honey bees. This project aims to use complex systems science to detect and prevent colony collapse in honey bees while advancing knowledge of tipping points in complex social systems. Understanding the mathematics of colony collapse can help us develop strategies for safeguarding managed bee populations and the valuable pollination services they provide. Expected outcomes include methods for the early detection of stress in colonies, methods for reversing declines, and new mathematical techniques for studying tipping points in complex social systems. This will provide significant benefits for Australian agriculture, much of which depends on bee pollination, while building scientific capacity in complex systems science.Read moreRead less

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.

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.
Sexual conflict and the evolution of nuptial gifts. This project aims to understand how sexual conflict drives the evolution of “manipulative” nuptial gifts in male arthropods and how females respond to ingesting these gifts. Nuptial food gifts comprise materials (other than sperm) that are offered by males to females to consume at mating, and are an integral feature of the mating systems of a wide variety of arthropods. The project will study the decorated cricket, a species where males produce ....Sexual conflict and the evolution of nuptial gifts. This project aims to understand how sexual conflict drives the evolution of “manipulative” nuptial gifts in male arthropods and how females respond to ingesting these gifts. Nuptial food gifts comprise materials (other than sperm) that are offered by males to females to consume at mating, and are an integral feature of the mating systems of a wide variety of arthropods. The project will study the decorated cricket, a species where males produce a nuptial food gift that contains a cocktail of chemicals known to influence female reproduction when eaten. The project is expected to strengthen Australia’s international standing in evolutionary research and help train the next generation of evolutionary biologists.Read moreRead less
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.
