Summary
How does the brain process conflicting information? Learning is the means by which we adapt to our environments. Occasionally, what we learn contradicts our present knowledge about the world. When this occurs, the old and new (contradictory) information compete for control over behaviour. Yet, how the brain processes contradictory information and resolves this competition is poorly understood. This project uses modern genetic tools in rodents to examine how the brain encodes and retrieves contra ....How does the brain process conflicting information? Learning is the means by which we adapt to our environments. Occasionally, what we learn contradicts our present knowledge about the world. When this occurs, the old and new (contradictory) information compete for control over behaviour. Yet, how the brain processes contradictory information and resolves this competition is poorly understood. This project uses modern genetic tools in rodents to examine how the brain encodes and retrieves contradictory information to influence behaviour. The outcomes include new insights regarding the neural basis of adaptive behaviour; and the benefits include an understanding of why we sometimes fail to adapt to change, and disorders characterized by such failures (e.g., anxiety disorders, addiction).Read moreRead less
Risky choices: From cells and circuits to computations and behaviour. This project aims to ask and answer fundamental questions about how we safely make risky decisions to guide our behaviour. It combines theoretically driven approaches from experimental psychology with state-of-the-art technology for mapping and manipulating brain function. The project expects to show, with unprecedented behavioural, brain cell type, and circuit precision, how we safely make choices, how these choices are shape ....Risky choices: From cells and circuits to computations and behaviour. This project aims to ask and answer fundamental questions about how we safely make risky decisions to guide our behaviour. It combines theoretically driven approaches from experimental psychology with state-of-the-art technology for mapping and manipulating brain function. The project expects to show, with unprecedented behavioural, brain cell type, and circuit precision, how we safely make choices, how these choices are shaped by experience, and how controlling these cells and circuits controls choice. This outcome should provide significant benefits including a new knowledge base bridging behavioural, cognitive, and neural sciences to advance theories of behaviour and laying a new basic science platform to understand impulsive behaviours.Read moreRead less

The plight of the bogong moth: a model for conservation in Australia. This project aims to direct conservation actions for the bogong moth, an endangered species of profound cultural, ecological, and economic importance to Australians. Although iconic and famous for their epic migration to the Australian Alps, the bogong moth's distribution and flyways are unknown making conservation actions impossible. This project expects to forge the key partnerships and harness public enthusiasm to generate ....The plight of the bogong moth: a model for conservation in Australia. This project aims to direct conservation actions for the bogong moth, an endangered species of profound cultural, ecological, and economic importance to Australians. Although iconic and famous for their epic migration to the Australian Alps, the bogong moth's distribution and flyways are unknown making conservation actions impossible. This project expects to forge the key partnerships and harness public enthusiasm to generate the data needed for conservation actions via a National Bogong Moth Observatory. The expected outcomes of this project are enhanced capacity to identify and mitigate threats to bogong moths. This should provide significant benefits such as a highly transferable model for continent-wide conservation in Australia.Read moreRead less
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
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.

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

Summary
Understanding the relationship between the social environment and cognition. The predominant theory for the evolution of intelligence, the social intelligence hypothesis (SIH), posits that within-group social interactions drive cognitive evolution. But the SIH overlooks a major component of social life: interactions with outsiders of the same species. Using a unique combination of meta-analytical and experimental approaches, the DECRA project will test the predictions of an expanded SIH, incorpo ....Understanding the relationship between the social environment and cognition. The predominant theory for the evolution of intelligence, the social intelligence hypothesis (SIH), posits that within-group social interactions drive cognitive evolution. But the SIH overlooks a major component of social life: interactions with outsiders of the same species. Using a unique combination of meta-analytical and experimental approaches, the DECRA project will test the predictions of an expanded SIH, incorporating the “Napoleonic” cognitive challenges posed by outsiders. The expected outcome is to gain a new understanding of which factors govern cognitive evolution – one of the longest-running debates in evolutionary biology.Read moreRead less
Vocal mimicry in songbirds. Many of the world’s largest clade of birds - the songbirds - incorporate vocal mimicry in their songs, but while scientific interest in vocal mimicry dates from Aristotle, limited progress has been made. With our unique research program we aim to provide an empirically based, theoretically informed understanding of avian vocal mimicry. In an important advance, we will examine both sexes to test long-held male-centric assumptions about evolutionary origins and maintena ....Vocal mimicry in songbirds. Many of the world’s largest clade of birds - the songbirds - incorporate vocal mimicry in their songs, but while scientific interest in vocal mimicry dates from Aristotle, limited progress has been made. With our unique research program we aim to provide an empirically based, theoretically informed understanding of avian vocal mimicry. In an important advance, we will examine both sexes to test long-held male-centric assumptions about evolutionary origins and maintenance of this trait. Crucially, we focus on lineages found only in Australia and PNG, where songbirds originated, to develop a robust scientific understanding of vocal mimicry across the entire songbird clade, and so provide an important new perspective on why and how song began.Read moreRead less
Uncovering a novel memory process mediating stimulus-based decisions. The project aims to describe how environmental stimuli influence choice between actions. The goal is to demonstrate that this influence recruits a novel form of memory characterised by a durable change in the expression of an opioid receptor. It will combine sophisticated behavioural tasks with modern genetic tools in rodents to identify the molecular, cellular and neural interactions underlying the acquisition, maintenance an ....Uncovering a novel memory process mediating stimulus-based decisions. The project aims to describe how environmental stimuli influence choice between actions. The goal is to demonstrate that this influence recruits a novel form of memory characterised by a durable change in the expression of an opioid receptor. It will combine sophisticated behavioural tasks with modern genetic tools in rodents to identify the molecular, cellular and neural interactions underlying the acquisition, maintenance and retrieval of this memory. The project expects to provide new insights into the brain machinery promoting motivated behaviours and adaptive decision-making, and to extend knowledge about the physiological underpinnings of our memories.

Gut-brain control of cue-induced feeding behaviours. This proposal aims to determine how food cues (e.g., advertisements) trigger our desire to eat. Using modern virally-mediated strategies, behavioural and histological techniques in a transgenic rat, this proposal seeks to characterise novel gut-brain circuits that mediate cue-induced feeding behaviours. This is significant as food cues can cause overeating, which is problematic in the current obesogenic society, yet the mechanisms are unclear. ....Gut-brain control of cue-induced feeding behaviours.

This is significant as food cues can cause overeating, which is problematic in the current obesogenic society, yet the mechanisms are unclear. This project expects to provide new knowledge on how the gut communicates with multiple brain regions to control cue-induced eating. This work should benefit the advancement of knowledge and establish a framework for future research on gut-brain mechanisms in cue-induced feeding.Read moreRead less

This project aims to provide the first quantification of the impact of feral cats on Australian reptiles, the country’s most diverse vertebrate lineage. This project expects to provide crucial missing pieces of the puzzle by adopting an innovative behavioural approach to determine how cats hunt for lizards, and how lizards respond to cat predation risk. The expected outcomes are an improved understanding of the capacity of native lizards to recognise cats as predators and respond appropriately, and a determination of the magnitude of threat that cats pose to native lizards. Importantly, our study aims to trial management strategies to mitigate the impact of cat predation on native reptiles.Read moreRead less
