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
Understanding the survival of forests under drought . Droughts are predicted to become more extreme in the near future, with potentially devastating impacts on Australian forest ecosystems. This project aims to address key knowledge gaps in our understanding of how plants tolerate extreme drought stress and utilise this new knowledge to improve vegetation models suitable for assessing ecosystem vulnerability. We will use innovative experimental methodology to determine the processes by which wat ....Understanding the survival of forests under drought . Droughts are predicted to become more extreme in the near future, with potentially devastating impacts on Australian forest ecosystems. This project aims to address key knowledge gaps in our understanding of how plants tolerate extreme drought stress and utilise this new knowledge to improve vegetation models suitable for assessing ecosystem vulnerability. We will use innovative experimental methodology to determine the processes by which water transport breaks down in roots, stems and leaves and the mechanisms governing recovery from severe drought stress. The project will provide a deeper understanding of drought tolerance in trees, improved forecasting of risks to native vegetation, and enhanced management of native forest resources.

Transgenerational Consequences of Different Environmental Experiences. The project aims to deliver an integrative overview of behavioural, evolutionary and environmental epigenetics. In particular, by studying why stress-related experiences of organisms (e.g. exposure to toxins) can be passed onto the future generations regardless of its seemingly fitness-reducing impacts. It also aims to test if the seemingly beneficial effect of non-stress related experiences (e.g. environmental enrichment) ca ....Transgenerational Consequences of Different Environmental Experiences. The project aims to deliver an integrative overview of behavioural, evolutionary and environmental epigenetics. In particular, by studying why stress-related experiences of organisms (e.g. exposure to toxins) can be passed onto the future generations regardless of its seemingly fitness-reducing impacts. It also aims to test if the seemingly beneficial effect of non-stress related experiences (e.g. environmental enrichment) can be inherited transgenerationally. This project involves both research synthesis (e.g. meta-analysis) and experiments on zebrafish employing cutting-edge statistical, computational and molecular methods along with behavioural assays. Also, the outcomes of the synthesis are expected to guide future work in the field. Read moreRead less
Sex chromosomes and speciation: chromosome inversion and the large Z-effect. This project aims to understand the divergence of species and the importance of two genomic features of often disproportionately large effect between young taxa – the sex chromosomes, and chromosome inversions. The research will integrate genomics and transcriptomics with the study of traits closely aligned to speciation in birds – song, colour, and sperm morphology and protein composition. The project will provide sign ....Sex chromosomes and speciation: chromosome inversion and the large Z-effect.

The research will integrate genomics and transcriptomics with the study of traits closely aligned to speciation in birds – song, colour, and sperm morphology and protein composition. The project will provide significant benefits such as enhancing Australia’s strength in the field of evolutionary biology.Read moreRead less
Animating the study of visual communication. This project aims to inform how dynamic colour signals broker information exchange by connecting stimulus design with perception through space and time. Biological studies of colour signalling have largely proceeded via static terms that underestimate the true fluidity of natural contexts. This project aspires to animate the field using innovative approaches such as programmable nano-drones to reveal how flashing colours are perceived under diverse vi ....Animating the study of visual communication. This project aims to inform how dynamic colour signals broker information exchange by connecting stimulus design with perception through space and time. Biological studies of colour signalling have largely proceeded via static terms that underestimate the true fluidity of natural contexts. This project aspires to animate the field using innovative approaches such as programmable nano-drones to reveal how flashing colours are perceived under diverse viewing conditions. The knowledge advances are expected to generate new intellectual paradigms and models, and have significant scope for bio-inspiration in areas such as telecommunication, information processing and the optimal design of visual displays.Read moreRead less
Buffering the ecosystem impact of invasive cane toads. This project aims to address the devastating ecological problems caused by invasive species, by developing a novel approach that does not rely upon eradicating the invader through training vulnerable native predators not to eat toxic cane toads. Expected outcomes of this project include building a broad coalition of conservation-focused groups, from private land-owners and local businesses through to Indigenous groups and government and non- ....Buffering the ecosystem impact of invasive cane toads. This project aims to address the devastating ecological problems caused by invasive species, by developing a novel approach that does not rely upon eradicating the invader through training vulnerable native predators not to eat toxic cane toads. Expected outcomes of this project include building a broad coalition of conservation-focused groups, from private land-owners and local businesses through to Indigenous groups and government and non-government agencies across the entire Kimberley region. It will also result in the evaluation of methods for deployment of taste-aversion at a landscape scale. This should provide significant benefits by conserving vulnerable fauna and building a powerful network within a region of high biodiversity in tropical Australia.Read moreRead less
