Preventing and reversing population declines of northern quolls. This project seeks to develop novel effective strategies to halt and reverse declines in northern quolls by improving their ‘toad-smart’ behaviour. The spread of cane toads threaten northern quolls, which are marsupial predators. We cannot halt the toad invasion, but we can train quolls not to eat cane toads. Trained quolls can survive long term in toad-infested landscapes, and their offspring can learn not to eat toads. This proje ....Preventing and reversing population declines of northern quolls. This project seeks to develop novel effective strategies to halt and reverse declines in northern quolls by improving their ‘toad-smart’ behaviour. The spread of cane toads threaten northern quolls, which are marsupial predators. We cannot halt the toad invasion, but we can train quolls not to eat cane toads. Trained quolls can survive long term in toad-infested landscapes, and their offspring can learn not to eat toads. This project builds on this work by focusing on cultural and genetic transmission of toad-smart behaviour. The project could save numerous quoll populations from extinction.Read moreRead less
Disentangling climate and evolutionary controls over the temperature dependence of leaf respiration. The project will use field and laboratory studies to establish if there are systematic differences in the temperature responses of leaf respiration in plants adapted to hot and cold environments. The results will enable climate modellers to better predict impacts of climate change on carbon exchange between vegetation and the atmosphere.
Growing up to be supersonic: bat echolocation origins and mechanics. This project aims to address the unresolved evolutionary origins of bat echolocation. Using a unique combination of development, evolution and novel engineering testing, this project expects to generate new insights into how features of the skull have evolved to allow bats to use their senses to interact with the environment. Expected outcomes include the identification of skull features that are unique to echolocating bats and ....Growing up to be supersonic: bat echolocation origins and mechanics. This project aims to address the unresolved evolutionary origins of bat echolocation. Using a unique combination of development, evolution and novel engineering testing, this project expects to generate new insights into how features of the skull have evolved to allow bats to use their senses to interact with the environment. Expected outcomes include the identification of skull features that are unique to echolocating bats and tests of how these relate to the frequency and detection range of sounds produced. Benefits include improved conservation planning for urban and rural bat populations, and potential commercial advances through engineering applications that mimic the biological process of echolocation.

Phenotypic plasticity and plant water use in a changing climate: a multi-species, multi-site investigation. Plants are highly responsive to the conditions under which they grow, but the combination of conditions they experience will be altered under climate change. This research into plant responses to the novel environments posed by climate change will examine plasticity in water-use-traits to better predict native plant tolerance of climate change.
How are visual gene pathways lost and restored during reptile evolution? This project aims to investigate how complex traits are lost during evolution, and once lost if they can be regained. The project will use the diverse visual systems of snakes and lizards to shed light on the process of gene loss in degenerative lineages, and discover the mechanisms that compensate for gene losses in taxa with secondarily evolved visual capabilities- providing a case of evolutionary re-innovation in complex ....How are visual gene pathways lost and restored during reptile evolution?

Adapting to a changing world: mothers as drivers of evolutionary change. This project will improve our understanding of how organisms will adapt to the unprecedented speed and magnitude of human-induced environmental change. By identifying how mothers modify their offspring to better match the prevailing environment, it will address the role of mothers in directing and accelerating adaptation in our changing world.
Evolution in tooth and claw: exploring the relationship between the radiation of marsupial herbivores and late Cenozoic climate change. Establishing how animals responded to past environmental changes is essential for understanding the ecology of modern species and managing them in light of contemporary climatic trends. By applying several novel analytical methods this project will unravel the links between the radiation of Australian marsupials and key stages in climatic evolution.
The evolution of light detection and its impacts on early vertebrate evolution. The eye is a complex organ crucial for survival. Tracing the evolution of the eye will not only provide basic concepts of how building visual complexity is achieved in nature but also enhance the understanding of the selection pressures driving the radiation of early vertebrates.
Does dynamic ecological change cause rapid evolution? This project aims to increase understanding of how Australia’s native biota responds to rapid environmental changes. Abrupt environmental change has the potential to drive rapid evolution, which may facilitate species persistence in the face of novel challenges. This project will use long-term genomic data to quantify rates of evolutionary change in species living in arid environments, whose populations fluctuate markedly in response to rainf ....Does dynamic ecological change cause rapid evolution? This project aims to increase understanding of how Australia’s native biota responds to rapid environmental changes. Abrupt environmental change has the potential to drive rapid evolution, which may facilitate species persistence in the face of novel challenges. This project will use long-term genomic data to quantify rates of evolutionary change in species living in arid environments, whose populations fluctuate markedly in response to rainfall variation. By measuring the pace of genomic change in these species, and the evolutionary processes driving that change, this project will reveal species’ evolutionary responses to major environmental fluctuations.Read moreRead less
The evolution of specialised orchid pollination and its reversibility. This project aims to determine the changes in key floral volatile compounds underpinning pollination transitions, identify their molecular basis, and understand the ecological processes favouring reversals away from extreme specialisation. By focusing on pollination of sexually deceptive Australian orchids, this project would be the first to determine the molecular, chemical and behavioural basis of evolutionary reversals to ....The evolution of specialised orchid pollination and its reversibility. This project aims to determine the changes in key floral volatile compounds underpinning pollination transitions, identify their molecular basis, and understand the ecological processes favouring reversals away from extreme specialisation. By focusing on pollination of sexually deceptive Australian orchids, this project would be the first to determine the molecular, chemical and behavioural basis of evolutionary reversals to more generalised strategies in a group of plants facing high risk of pollinator extinction. The expected outcome, a mechanistic understanding of how pollination transitions occur, would be internationally ground-breaking, and provide crucial insights to protect this diverse but highly threatened group of plants.Read moreRead less
