Range dynamics and demographics of spatially structured populations under global change. Why are particular species present in some locations, but not others? This is a simple, fundamental ecological question, yet surprisingly, our answers on this point remain far from complete. Using an integrated, systems-based approach, we will determine the interplay between: (i) birth, death and movement rates, (ii) species interactions, and (iii) the constraints of the physical environment (temperature, ra ....Range dynamics and demographics of spatially structured populations under global change. Why are particular species present in some locations, but not others? This is a simple, fundamental ecological question, yet surprisingly, our answers on this point remain far from complete. Using an integrated, systems-based approach, we will determine the interplay between: (i) birth, death and movement rates, (ii) species interactions, and (iii) the constraints of the physical environment (temperature, rainfall, soil type), which determine the limits of species' ranges. Our models will provide Australian conservation managers with a novel, validated toolbox to explore the trade-offs, and synergies, inherent in trying to adapt to climate change and other stressors on biodiversity.Read moreRead less
Reconstructing the impact of climate change on Australian native species. This project will explore the impact of past climate change on Australian native animals to identify species and ecosystems at greatest potential risk, and to help predict and minimise the effects of future change.
How do we seek justice after hurt, offence or terror? Retributive and restorative responses. The project will address a neglect of the concept of restorative justice in psychology. It will add to the leadership on this issue of Australian researchers from other disciplines and contribute to Australia's worldwide reputation in this field. The project will determine when people are motivated to use restorative justice. Hence, it will contribute to the effective implementation of restorative justic ....How do we seek justice after hurt, offence or terror? Retributive and restorative responses. The project will address a neglect of the concept of restorative justice in psychology. It will add to the leadership on this issue of Australian researchers from other disciplines and contribute to Australia's worldwide reputation in this field. The project will determine when people are motivated to use restorative justice. Hence, it will contribute to the effective implementation of restorative justice practices, for them to be considered legitimate and able to contribute to the reduction of crime, to reconciliation after conflict and international peace. The research seeks to make a contribution to a safer, more cohesive Australia and inform its missions for conflict resolution (in the region) and thus reduce causes of terrorism.Read moreRead less
Generalised methods for testing extinction dynamics across geological, near and modern time scales. The record of extinctions over deep time is patchy and incomplete, yet we must use it to determine how major changes in past environments have shaped life on Earth today. The project will develop cutting-edge mathematical tools to determine the patterns of extinctions and speciation over geological time to help predict our uncertain environmental future.
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.
Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidenc ....Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidence of these keystones’ cellular level biogeochemical and metabolic capacity. Ultimately, this knowledge is expected to predict the resilience of ocean ecosystems and their response to change. The capacity to predict their dynamics will help provide investment clarity and increase healthy outcomes from activities involving human-ocean interactions such as recreation, food production and tourism.Read moreRead less
The evolution of egg retention and sex allocation: a phylogenetic contrasts study using facultatively ovoviviparous thrips. Australian idolothripine thrips provide an unparalleled opportunity for investigating the evolution of reproduction. They constitute the only group to contain many species in which the females choose among live birth, egg laying or both. They also choose the sex of each offspring. We will use phylogenetics and experimentation to understand the evolutionary pressures that le ....The evolution of egg retention and sex allocation: a phylogenetic contrasts study using facultatively ovoviviparous thrips. Australian idolothripine thrips provide an unparalleled opportunity for investigating the evolution of reproduction. They constitute the only group to contain many species in which the females choose among live birth, egg laying or both. They also choose the sex of each offspring. We will use phylogenetics and experimentation to understand the evolutionary pressures that led to and maintain live birth and the allocation of sex. This will produce new insights into fundamental questions about the evolution of animal reproduction. Our collaborative approach will make Australian thrips and research an international cornerstone in the biology of reproductive evolution.Read moreRead less
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.
Parasite transmission through social networks in the pygmy bluetongue lizard. Australia's biodiversity is continually threatened by new epidemics of diseases and parasites, some local, others from overseas. This project will provide information on how they spread so that more effective management of these diseases can be developed to protect wildlife species, animal populations and, ultimately, Australian ecosystems.
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?
