Australian savannah landscapes: past, present and future. Australian savannahs are productive and culturally and biologically significant landscapes but are vulnerable to climate change. The project will determine savannah function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.

This project aims to estimate the economic loss of workplace heat exposure in Australia. The project will investigate the health services costs of occupational heat-related illnesses/injuries, explore the labour productivity loss and its costs resulting from heat stress at work, and estimate the benefits from a generic heat warning intervention for workplace heat prevention. Outcomes are expected to provide an overview of national economic implications at present and in the future from effective heat stress control, assist the development of work place heat policies, and inform resource allocation to make Australian workplaces well prepared for likely increasing extremely hot weather.Read moreRead less

Are evolutionary refugia traps for endemic species? This project aims to determine whether species that have small geographic ranges and which live in historically stable refugia have evolved narrow climatic tolerances. The project will compare such species with more widespread, related species living in the same areas and combine field- and lab-based estimates of physiological tolerances with genomic estimates of population history and diversity. The expected outcome is to test the prediction f ....Are evolutionary refugia traps for endemic species? This project aims to determine whether species that have small geographic ranges and which live in historically stable refugia have evolved narrow climatic tolerances. The project will compare such species with more widespread, related species living in the same areas and combine field- and lab-based estimates of physiological tolerances with genomic estimates of population history and diversity. The expected outcome is to test the prediction from evolutionary theory that small-range, refugial species are intrinsically more sensitive to climatic change. The project expects to provide improved guidance for ecological management of biodiversity hotspots.Read moreRead less
Do marine heat waves cause pathogen outbreaks in Australian coastal waters? This project aims to identify links between increasingly frequent Marine Heat Wave (MHW) events and outbreaks of microbes that cause disease in marine animals, reduced aquaculture yields and human health hazards. Pathogenic bacteria from the Vibrio genus exhibit a preference for elevated seawater temperature and this project will test the hypothesis that episodic MHWs will trigger blooms of dangerous species. Using innov ....Do marine heat waves cause pathogen outbreaks in Australian coastal waters? This project aims to identify links between increasingly frequent Marine Heat Wave (MHW) events and outbreaks of microbes that cause disease in marine animals, reduced aquaculture yields and human health hazards. Pathogenic bacteria from the Vibrio genus exhibit a preference for elevated seawater temperature and this project will test the hypothesis that episodic MHWs will trigger blooms of dangerous species. Using innovative ecogenomic tools, this project will track the impact of MHWs on the dynamics of pathogenic Vibrio within coastal habitats, oyster farming facilities and coral reefs. The benefit of this project will be essential new knowledge on an emerging threat to Australia’s valuable marine estate, food security and public health.Read moreRead less
Demographic consequences of Asian disasters: family dynamics, social capital and migration patterns. This study of the long term demographic consequences of Asian disasters will contribute to development of more effective governmental policies on disaster mitigation, preparedness and reconstruction/recovery, thus assisting to reduce the human and material losses from natural disasters.
Plant-herbivore interactions: a model two-species system from northern Australia. The proposed research addresses a critical aspect of magpie goose ecology. Understanding the interaction between the birds and the bulbs is critical to respond effectively to past and threatened losses of important sedge habitats to sea level rise. This knowledge will inform management of the Kakadu World Heritage Site and an iconic waterfowl of great cultural and economic significance. In addition to their importa ....Plant-herbivore interactions: a model two-species system from northern Australia. The proposed research addresses a critical aspect of magpie goose ecology. Understanding the interaction between the birds and the bulbs is critical to respond effectively to past and threatened losses of important sedge habitats to sea level rise. This knowledge will inform management of the Kakadu World Heritage Site and an iconic waterfowl of great cultural and economic significance. In addition to their importance as a Gondwanan relic and sole member of the Family Anseranatidae, the species is an important food-source for Aboriginal people, and tourists travel to the Kakadu wetlands to witness huge dry season congregations.Read moreRead less
Modelling Payments for Environmental Services on Indigenous held lands. Payments for environmental services (PES) such as fire management have potential to provide employment to indigenous people managing land that has previously been thought to hold no commercial value. In so doing it could transform the economies of the very remote parts of Australia where indigenous people live. For these schemes to work, however, greater understanding is required not only of the willingness of society to pay ....Modelling Payments for Environmental Services on Indigenous held lands. Payments for environmental services (PES) such as fire management have potential to provide employment to indigenous people managing land that has previously been thought to hold no commercial value. In so doing it could transform the economies of the very remote parts of Australia where indigenous people live. For these schemes to work, however, greater understanding is required not only of the willingness of society to pay for environmental services in northern Australia but also of the perceptions of the indigenous people who are providing these services. Choice modelling can (1) quantify values of different environmental services in different sectors of society and (2) help allocate the payments for environmental services efficiently.Read moreRead less
Density regulation as a major determinant of population persistence: advancing empirical and theoretical approaches to conserve biodiversity. Without efficient application of limited conservation resources, more species will go extinct and invasive species will continue to proliferate. With a better understanding of extinction processes, a higher benefit:cost ratio will ensure better outcomes for biodiversity. We will directly address (1) the sustainable use of Australia's biodiversity by provid ....Density regulation as a major determinant of population persistence: advancing empirical and theoretical approaches to conserve biodiversity. Without efficient application of limited conservation resources, more species will go extinct and invasive species will continue to proliferate. With a better understanding of extinction processes, a higher benefit:cost ratio will ensure better outcomes for biodiversity. We will directly address (1) the sustainable use of Australia's biodiversity by providing evidence-based support for minimum viable population size targets to avoid extinction; (2) responding to climate change by determining the species- and environmentally specific contexts leading to elevated risks of extinction; and (3) protecting Australia from invasive diseases and pests by determining density targets that maximise eradication success.Read moreRead less
Effects of maternal foraging success and oceanographic variation on offspring behaviour and survival in the southern elephant seal. Juvenile survival is the key determinant of mammalian population performance, but the proximate determinants of this have rarely been established in large, long-lived predators. Southern elephant seals, with their concentrated lactation effort and marked separation of energy acquisition (at-sea foraging) and expenditure (on-land lactation) provide an ideal model for ....Effects of maternal foraging success and oceanographic variation on offspring behaviour and survival in the southern elephant seal. Juvenile survival is the key determinant of mammalian population performance, but the proximate determinants of this have rarely been established in large, long-lived predators. Southern elephant seals, with their concentrated lactation effort and marked separation of energy acquisition (at-sea foraging) and expenditure (on-land lactation) provide an ideal model for investigating these factors. In this study, we investigate the partitioning of pre-partum performance (fat acquired in mothers) relative to spatial-temporal variation in ocean productivity and the effect of this expenditure on offspring condition and survival. Here, the final missing link of energy transfer and its effects on offspring will be a major outcome of this project.Read moreRead less
