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
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. 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 ....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. 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
An evolutionary approach to understanding chemical cues used in mate choice. This project will combine evolutionary biology with molecular and chemical ecology to gain a fundamental understanding of the role chemicals play in animal communication. By drawing on novel and innovative techniques, this project will place Australia at the forefront of this discipline and contribute to Australia's capacity to control pests.
What drives parasite spread through social networks: lessons from lizards. Australia's biodiversity is continually threatened by new epidemics of local and foreign diseases and parasites. This project will enhance our understanding of how these diseases spread, allowing more effective controls to be developed to protect wildlife species, animal populations and, ultimately, Australian ecosystems.
Manipulating population sex ratio to eradicate invasive mouse populations. This project aims to use house mice, an Australian pest of economic importance which is also a highly tractable system for testing evolutionary theory and generating practical outcomes. Manipulating population sex ratio is a powerful tool for either enhancing the viability of threatened species or decimating pests. However, despite much scientific effort testing sex ratio theory, the cryptic mechanisms driving sex allocat ....Manipulating population sex ratio to eradicate invasive mouse populations. This project aims to use house mice, an Australian pest of economic importance which is also a highly tractable system for testing evolutionary theory and generating practical outcomes. Manipulating population sex ratio is a powerful tool for either enhancing the viability of threatened species or decimating pests. However, despite much scientific effort testing sex ratio theory, the cryptic mechanisms driving sex allocation remain unidentified, hindering progress in these fields. The project will identify the mechanisms by which sex ratio adjustments are made and establish how individual-level responses influence insular population structure and growth. It will provide benefits by assisting Australia's efforts in eradicating invasive mouse populations.Read moreRead less

Summary
Assessing pollination services of honey bees in native ecosystems and threats posed by parasites. The European honeybee is our most abundant pollinator but we know little about its role in native Australian ecosystems or how its many diseases may affect its ability to pollinate. This project will determine whether honeybees are important pollinators of native plants and how a common parasite affects their pollination ability.
Threshold evolution: conceptualising decisions as traits. All organisms make decisions, yet the diversity of decision rules across the spectrum of life can be understood through a few key evolutionary models. This project will test these models and then apply them to understanding topics as diverse as pest outbreaks, human twinning, sex ratio evolution and disease spread as a consequence of climate change.
