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

This project aims to improve knowledge about the central role that animal social behaviour plays in the spread of emerging infectious fungal diseases in nature. Applying approaches from behavioural ecology, network modelling and quantitative genetics, and utilising rare empirical pre- and post-infection data, the project expects to generate new understandings about how fungal diseases spread through animal populations, how animal social behaviour influences disease transmission, and how disease-status affects animal social behaviour. This project should have international impact, and advance current knowledge about disease dynamics. Applied outcomes should inform much-needed control strategies to benefit wildlife and preserve biodiversity. Read moreRead less
Why are warning colours in animals so rare? Toxic insects display warning colours as protection from predators who learn to associate them with an unpleasant taste. Theoretically, there is no limit to the number of species that could show warning colours but only about 5% are estimated to have them. This presents a fundamental and unresolved biological problem - what limits warning colours? This project aims to address this significant biological question by testing three hypotheses predicting w ....Why are warning colours in animals so rare? Toxic insects display warning colours as protection from predators who learn to associate them with an unpleasant taste. Theoretically, there is no limit to the number of species that could show warning colours but only about 5% are estimated to have them. This presents a fundamental and unresolved biological problem - what limits warning colours? This project aims to address this significant biological question by testing three hypotheses predicting warning signal limitations. Projected outcomes are an improved understanding of the ecological niche of these colourful insects, which may inform conservation and biodiversity management and raise awareness of these flamboyant creatures.Read moreRead less

This project expects to generate new knowledge in the fields of behavioural and pollination ecology through a combination of field experiments and modelling. Expected outcomes of this project include enhanced capacity in the field of pollination ecology, and new insight into flower preferences in the world’s most important commercial pollinator. This should provide significant benefits to food production and security as one third of the world’s crops benefit from insect pollination.Read moreRead less
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
Defining winning strategies in a changing Southern Ocean . The ecosystem of the Southern Ocean is extremely complex, and understanding its response to rapid climate change is challenging.

The ecosystem of the Southern Ocean is extremely complex, and understanding its response to rapid climate change is challenging. The aim of the project is to use changes in the behaviour of marine predators to provide new measures of integrated changes in eastern Antarctic ecosystems throughout the winter. With novel combinations of electronic tagging, natural biogeochemical markers, and simulation modelling, the project expects to reconstruct changes in animal behaviour in response to changes in the environment. The data is anticipated to explain ongoing large-scale shifts in Southern Ocean ecosystems, providing information needed to underpin future management and adaptation strategies.Read moreRead less
A sentinel network for vibration-based termite control. Termite damage is costly and eradication via chemicals is hazardous to environment and health. As termites use vibrations to make foraging decisions and eavesdrop on competitors/predators, it is feasible but not attempted hitherto to detect and control termites using vibrations.

Termite damage is costly and eradication via chemicals is hazardous to environment and health. As termites use vibrations to make foraging decisions and eavesdrop on competitors/predators, it is feasible but not attempted hitherto to detect and control termites using vibrations. A smart sentinel network will be developed to enable timber infrastructure to be continuously monitored for termites and for termites to be repelled using specific vibration signals and manipulated structures, with minimal environmental and health impacts. For this network to be efficient and effective, an improved understanding on how vibrations influence termite sociality will be obtained by studying habituation and signal adaptation on collective behaviour.Read moreRead less
Discovering how termites use vibrations to thrive in a predators' world. Our recent research revealed termites use vibrations to avoid predators/competitors for survival. However, the enabling mechanisms of this amazing ability remain unknown. The project aims at unlocking the secrets of these mechanisms by relating the mechanical properties of termite, legs, antennae and sensing organs (measured with advanced micro measurement techniques) to vibration signatures of ants and termites (extracted ....Discovering how termites use vibrations to thrive in a predators' world. Our recent research revealed termites use vibrations to avoid predators/competitors for survival. However, the enabling mechanisms of this amazing ability remain unknown. The project aims at unlocking the secrets of these mechanisms by relating the mechanical properties of termite, legs, antennae and sensing organs (measured with advanced micro measurement techniques) to vibration signatures of ants and termites (extracted using innovative signal processing techniques and nonlinear dynamics). We will develop novel bio-dynamics models that incorporate machine learning. We will test the models’ ability to manipulate termites foraging behaviour, with the ultimate objective of developing chemical-free, vibration-based pest control devices. Read moreRead less
