Summary
Understanding bioacoustics in plants. From lush tropical rainforests to small urban gardens, plants take advantage of the surrounding soundscape to flourish, yet how they do this is still unknown. This will be the first experimental study to explore how and why plants sense sound in their environment, hence pioneering a brand-new research area in behavioural and evolutionary ecology.
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.
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

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.
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

Summary
The evolutionary significance of ejaculate-female interactions. The way that ejaculates interact with the female reproductive tract is thought to have profound evolutionary implications in internal fertilizers. Yet we currently lack clear insights into these processes in most taxa, precisely because such ejaculate-female interactions are hidden from view inside the female's reproductive tract. In this project an integrated series of experiments on a model vertebrate (the guppy) will overcome the ....The evolutionary significance of ejaculate-female interactions. The way that ejaculates interact with the female reproductive tract is thought to have profound evolutionary implications in internal fertilizers. Yet we currently lack clear insights into these processes in most taxa, precisely because such ejaculate-female interactions are hidden from view inside the female's reproductive tract. In this project an integrated series of experiments on a model vertebrate (the guppy) will overcome the inherent challenges in studying ejaculate-female interactions. The project aims to shed new light on the role that ejaculate-female interactions play in sperm competition, and will explore the consequences of these interactions at different evolutionary levels and across varying social environments.Read moreRead less
The benefits of sociality: understanding the relationship between cooperation, cognition and fitness. Cooperation may present unique cognitive challenges. Individuals perform behaviours that provide fitness benefits to others, exposing themselves to risk. The need to monitor the behaviour of group members, recognise suitable cooperative partners, and make corresponding behavioural adjustments to maximize the benefits of cooperation, may therefore be an important driver of social evolution. The r ....The benefits of sociality: understanding the relationship between cooperation, cognition and fitness. Cooperation may present unique cognitive challenges. Individuals perform behaviours that provide fitness benefits to others, exposing themselves to risk. The need to monitor the behaviour of group members, recognise suitable cooperative partners, and make corresponding behavioural adjustments to maximize the benefits of cooperation, may therefore be an important driver of social evolution. The relevance of understanding the relationship between cognition and cooperation is in how it affects the fitness of individuals and the stability of cooperation. This project aims to unveil this relationship by conducting one of the first comprehensive studies of the selective benefits of cognitive ability in a wild, cooperative bird species.Read moreRead less
Integrating pre- and postcopulatory sexual selection. This project combines life-history theory, behaviour, physiology and quantitative genetics to gain a broader understanding of the mechanisms linking pre- and postcopulatory sexual selection. The work will boost Australia’s profile in evolutionary ecology and build new collaborative links with researchers overseas.
Dynamic assessment of threats to marine megafauna in face of global change. This project aims to develop a global approach to synthesise global tracking datasets and deliver near real-time diagnostics on risks for marine megafauna at a global scale pushing forward a new frontier in dynamic marine spatial management to improve conservation.

This project aims to develop a global approach to synthesise global tracking datasets and deliver near real-time diagnostics on risks for marine megafauna at a global scale pushing forward a new frontier in dynamic marine spatial management to improve conservation. This project expects to increase our understanding of how marine megafauna movements vary with environmental changes and how much they overlap with threatening global human activities. Expected outcomes will demonstrate how big data in marine telemetry can be synthesised and translated into ecologically significant behaviours. This should provide significant benefits to address global scientific and societal problems highlighted in the Australian science and research priorities.Read moreRead less
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.
