Ocean basin-scale migrations of iconic sea turtles, marine mammals, seabirds, and fish expose them to multiple stressors and governance regimes, leading to gaps in management and population declines. The project aims to deliver the methods and evidence base of cross-taxa migratory connectivity that is essential to support the
conservation of these species. Expected outcomes include comprehensive and integrated models of mig ....Understanding marine migratory connectivity for more sustainable oceans. Ocean basin-scale migrations of iconic sea turtles, marine mammals, seabirds, and fish expose them to multiple stressors and governance regimes, leading to gaps in management and population declines. The project aims to deliver the methods and evidence base of cross-taxa migratory connectivity that is essential to support the
conservation of these species. Expected outcomes include comprehensive and integrated models of migratory connectivity, conservation theory development, and new methods that allow incorporation of migratory connectivity in conservation planning. Benefits include: a cross-taxa baseline that will enable Australia to measure environmental change in marine migratory connectivity for the first time.Read moreRead less
An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host ....An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host and symbiont response to changing water temperature along a latitudinal gradient. The intended outcome of the project is to provide knowledge to support predictions of likely species migrations from tropical to subtropical waters, enabling managers to anticipate the future response of coral communities to seawater warming.Read moreRead less
Temperate trophic cascades: impacts of seal foraging on benthic community dynamics. Effective Marine Protected Area management across Australia requires guidance from rigorous strategic research. The project will investigate opposing activities that provoke ecosystem collapse (overharvesting, grazing) or recovery (marine park protection) and provide advice to improve effectiveness of marine conservation strategies in New South Wales and South Australia.
Novel species interactions arising from synergistic environmental changes. Synergistic environmental changes, including climate and land use change, are altering Australia's ecosystems and creating novel species assemblages. We know little about how these assemblages develop and function, and yet they are likely to become more pervasive and provide a significant conservation and restoration challenge. We aim to improve our understanding of the factors affecting the creation of novel plant assemb ....Novel species interactions arising from synergistic environmental changes. Synergistic environmental changes, including climate and land use change, are altering Australia's ecosystems and creating novel species assemblages. We know little about how these assemblages develop and function, and yet they are likely to become more pervasive and provide a significant conservation and restoration challenge. We aim to improve our understanding of the factors affecting the creation of novel plant assemblages (through invasions and changes in species' ranges) in the York Gum woodlands of Western Australia. We will examine how novel assemblages function, improve the ability to predict potential ongoing changes in assemblages and provide guidance for the management of these and other internationally important plant communities.Read moreRead less
How do ecologically significant complex traits evolve in natural populations? Evolution and selection on plant chemistry in Eucalyptus. The scent of Eucalyptus oil is one of the signatures of Australia but we actually import large amounts of these oils. As well as being valuable industrially, Eucalyptus oils also influence many aspects of our environment ranging from icons such as the koala to the occurrence of smog in cities. Understanding how plants make these oils helps us to understand eco ....How do ecologically significant complex traits evolve in natural populations? Evolution and selection on plant chemistry in Eucalyptus. The scent of Eucalyptus oil is one of the signatures of Australia but we actually import large amounts of these oils. As well as being valuable industrially, Eucalyptus oils also influence many aspects of our environment ranging from icons such as the koala to the occurrence of smog in cities. Understanding how plants make these oils helps us to understand ecological processes and also to improve the financial incentives for land restoration through the planting of valuable oil-bearing trees. We aim to use recent new techniques in genetics to explain why the quantity and types of Eucalyptus oils vary so widely and to apply this information to improving land management and conservation.Read moreRead less
Pathways to semelparity versus early maturity in animals and plants. The project aims to resolve an important but unresolved question in life history evolution and ecology- which mechanisms and constraints lead to semelparity (breeding once, which is rare), and which lead to fast life history (breeding early, which is common) in animals and plants. Theory predicts that both may be adaptations to schedules of adult death. Understanding why males and females have either semelparous or fast life hi ....Pathways to semelparity versus early maturity in animals and plants. The project aims to resolve an important but unresolved question in life history evolution and ecology- which mechanisms and constraints lead to semelparity (breeding once, which is rare), and which lead to fast life history (breeding early, which is common) in animals and plants. Theory predicts that both may be adaptations to schedules of adult death. Understanding why males and females have either semelparous or fast life history strategies is crucial to predicting survival of harvested and threatened species under pressure from climate change, drought, predators, and diseases that kill adults. Expected project outcomes include improved ability to address agents of decline of threatened animals and plants including semelparous species.Read moreRead less
Phyloinformatics and biodiversity: developing bioinformatic tools for understanding the dynamics of extinction and invasion within species assemblages. DNA sequence data provides an exciting new way to study biodiversity, because the genome of each organism records its evolutionary history. By analysing DNA sequences co-existing species, we can reconstruct the ecological and evolutionary history of a biological community. This allows us to track biodiversity changes over time, and examine how th ....Phyloinformatics and biodiversity: developing bioinformatic tools for understanding the dynamics of extinction and invasion within species assemblages. DNA sequence data provides an exciting new way to study biodiversity, because the genome of each organism records its evolutionary history. By analysing DNA sequences co-existing species, we can reconstruct the ecological and evolutionary history of a biological community. This allows us to track biodiversity changes over time, and examine how the state of a species assemblage determines which species are lost through extinction or gained through the invasion of exotic species. Understanding the factors that govern changes in biodiversity over time is essential for planning for future conservation in the face of a rapidly changing environment. Read moreRead less

This project will provide new understanding of the role of Australia's only native large mammal predator in sustaining biodiversity and ecological function. This will result in improved management of dingoes as a key part of Australian ecosystems. The project will also test the possibility that relaxation of current controls on dingoes could provide net benefits to beef cattle producers, and thereby improve the viability and sustainability of Australia's cattle-grazing industry.Read moreRead less
Ecology and conservation of a unique, threatened guanophilic invertebrate community. This project aims to study the biology and ecology of a unique assemblage of insects and other invertebrates that live specifically in bat guano at Naracoorte Caves World Heritage Area. The caves are a major ecotourism and research location because of their world famous Pliestocene fossils, and because one cave is a critical breeding site for the large bentwing bat, Miniopterus s. bassianii. The guano cave, whic ....Ecology and conservation of a unique, threatened guanophilic invertebrate community. This project aims to study the biology and ecology of a unique assemblage of insects and other invertebrates that live specifically in bat guano at Naracoorte Caves World Heritage Area. The caves are a major ecotourism and research location because of their world famous Pliestocene fossils, and because one cave is a critical breeding site for the large bentwing bat, Miniopterus s. bassianii. The guano cave, which contains numerous endemic invertebrates, is potentially threatened by both direct and indirect human impacts. The results of this research will form the basis of a long-term management strategy to conserve this diverse community.Read moreRead less
Orientation in the pelagic environment: how do larval marine fish find their way home? This study will determine what senses tiny fish larvae use to orientate in the ocean and to influence where currents disperse them. Because larval dispersal determines the spatial extent of fish populations, this knowledge is important for management of marine fisheries and the design and operation of marine parks.
