The Cambrian Population Explosion of Arthropods in Australia: Ediacaran origins, evolution and biodiversity. This project addresses key questions on the origin and diversification of life, by investigating the evolution of the most important fossil group (arthropods) across arguably the most important event after the origin of life (the Cambrian explosion of macroscopic life). It will also excavate, promote and conserve two key geological resources of national importance, in the Flinders Ranges ....The Cambrian Population Explosion of Arthropods in Australia: Ediacaran origins, evolution and biodiversity. This project addresses key questions on the origin and diversification of life, by investigating the evolution of the most important fossil group (arthropods) across arguably the most important event after the origin of life (the Cambrian explosion of macroscopic life). It will also excavate, promote and conserve two key geological resources of national importance, in the Flinders Ranges and Kangaroo Island. Also, it will lead to increased knowledge of the palaeoecology and geology of the economically-important Adelaide geosyncline, and benefit rural SA communities through ecotourism, a rural schools education program, and public outreach.Read moreRead less
Evolving landscapes of our early South African ancestors. This project aims to reconstruct the early evolution of our genus, from 2.6 to 1.8 million years ago. This was a time of faunal and environmental change, the extinction of apelike human ancestors (Australopithecus), the speciation of a specialised human genus, Paranthropus, and the origin of our own genus, Homo. This project will study South African cave sites, the surrounding karst, and the oldest known Homo ergaster fossil to model chan ....Evolving landscapes of our early South African ancestors. This project aims to reconstruct the early evolution of our genus, from 2.6 to 1.8 million years ago. This was a time of faunal and environmental change, the extinction of apelike human ancestors (Australopithecus), the speciation of a specialised human genus, Paranthropus, and the origin of our own genus, Homo. This project will study South African cave sites, the surrounding karst, and the oldest known Homo ergaster fossil to model changing dietary patterns and landscape use by hominins. This project expects to reconstruct the early evolution of our genus and to address how species reacted to changing environmental conditions and increasing aridity.Read moreRead less
Improved management of coastal plankton systems by ancient DNA technology. This project aims to assemble comprehensive long term Australian plankton records spanning 50 to 1000 years, by applying ancient DNA technology to dated sediment depth cores. Long-term data for Australian coastal and estuarine waters are sparse, so cannot be used for management of fisheries, tourism or urban development. Long-term records are essential to understand how disruptive algal and jellyfish blooms, introduced sp ....Improved management of coastal plankton systems by ancient DNA technology. This project aims to assemble comprehensive long term Australian plankton records spanning 50 to 1000 years, by applying ancient DNA technology to dated sediment depth cores. Long-term data for Australian coastal and estuarine waters are sparse, so cannot be used for management of fisheries, tourism or urban development. Long-term records are essential to understand how disruptive algal and jellyfish blooms, introduced species and increased human use of coastal resources affect dynamic plankton ecosystems. This project’s findings are expected to explore cyclical patterns, define range expansions and understand and manage how dynamic coastal ecosystems respond to multistressor anthropogenic change. Findings will improve understanding of how dynamic marine environments retain their biodiversity values and critical ecological functions.Read moreRead less
The mighty ape’s last stand. This project aims to study the fate of primates in southern Asia, where evidence for megafaunal extinction is rare. Why Gigantopithecus blacki, the largest ever primate, disappeared is unknown, while humans in the region survived. This project will model dating techniques across sites to identify a precise extinction window and compare behaviour and past environmental conditions to determine why the ape failed and man persevered. Outcomes will generate a new understa ....The mighty ape’s last stand. This project aims to study the fate of primates in southern Asia, where evidence for megafaunal extinction is rare. Why Gigantopithecus blacki, the largest ever primate, disappeared is unknown, while humans in the region survived. This project will model dating techniques across sites to identify a precise extinction window and compare behaviour and past environmental conditions to determine why the ape failed and man persevered. Outcomes will generate a new understanding of past environmental change as a driver of megafaunal extinction in comparison with human adaption and survival.Read moreRead less
Size matters: evolution of body size of species in deep time. Global warming is predicted to form 'sick seas' and cause widespread stunted growth of taxa and ecosystem-wide dwarfism. Exactly how this works requires substantiation of both short-term empirical and experimental research as well as evidence from the deep-time fossil record. Using the high-resolution marine fossil record from the Permian-Triassic mass extinction ~252 million years ago, the most severe in the history of animals, this ....Size matters: evolution of body size of species in deep time. Global warming is predicted to form 'sick seas' and cause widespread stunted growth of taxa and ecosystem-wide dwarfism. Exactly how this works requires substantiation of both short-term empirical and experimental research as well as evidence from the deep-time fossil record. Using the high-resolution marine fossil record from the Permian-Triassic mass extinction ~252 million years ago, the most severe in the history of animals, this project will investigate how body size of marine species and communities evolved in response to the mass extinction and rapid global warming. It is expected that the project findings will help better understand the links between global warming, anoxia, hypercapnia, euxinia, ocean acidification, and species adaptation and evolution.Read moreRead less
Developing a geomorphological framework to underpin management decision-making on the Great Barrier Reef. The paucity of data on coral reef growth histories inhibits attempts to integrate regional reef growth data into coral reef management - despite the major influence on habitat type and diversity. This project will gather such data for one region of the Great Barrier Reef, and develop such datasets to support future reef management decision-making.
Determining fossilisation processes of a rare iron-rich Lagerstätte. Most fossil sites only preserve resistant elements such as bones and teeth, leading to questions about how soft animals and structures have evolved over time. The recent discovery of a fossil deposit in New South Wales appears to demonstrate a new set of conditions for the preservation of soft tissues. This project aims to constrain the age of and assess the fossilisation processes that produced this unique fossil site. We will ....Determining fossilisation processes of a rare iron-rich Lagerstätte. Most fossil sites only preserve resistant elements such as bones and teeth, leading to questions about how soft animals and structures have evolved over time. The recent discovery of a fossil deposit in New South Wales appears to demonstrate a new set of conditions for the preservation of soft tissues. This project aims to constrain the age of and assess the fossilisation processes that produced this unique fossil site. We will use an integrative approach to reconstruct the formation of this Lagerstätte. The work will provide significant advances in our understanding of the process of fossilisation and guide the discovery of other exceptionally-well preserved fossil deposits, critical in reconstructing the biological history of Australia.Read moreRead less
Uncovering ancient landscapes with emerging technologies: integrating complex geospatial and fossil data to explore late Cenozoic environmental change. This project aims to use emerging technologies to unravel relationships between prehistoric climate changes and environmental impacts in northern Australia. Given current uncertainty about impacts of contemporary climate change on our biota, it is important to document the outcomes of past climatic changes and, in particular, the globally critica ....Uncovering ancient landscapes with emerging technologies: integrating complex geospatial and fossil data to explore late Cenozoic environmental change. This project aims to use emerging technologies to unravel relationships between prehistoric climate changes and environmental impacts in northern Australia. Given current uncertainty about impacts of contemporary climate change on our biota, it is important to document the outcomes of past climatic changes and, in particular, the globally critical period between 15 and five million years ago that shaped modern Australian environments. Fossil-rich deposits in the Riversleigh World Heritage Area of northern Queensland span this period. Interpretation of their fine-grained record of impact and change will improve our ability to predict and hence better manage impacts of future climate change on our unique national natural heritage.Read moreRead less
Developing reliable chronologies for extinct Australian Pleistocene megafauna from museum fossil collections. Our ability to understand the timing of prehistoric extinction events is critical, but can only be achieved by reliable dating methods. This project will adopt several new and exciting methodologies in the direct dating of fossils to determine the chronological sequence and the timing of extinction of the Pleistocene megafauna.
Dark canaries: new multidisciplinary understanding about the origins, radiation and response to environmental change of southern hemisphere bats. This project will overhaul global understanding of the origins of bats, their flight patterns and the role of echolocation in resource partitioning in an environmentally changing Australia. It will also provide information vital for conservation and novel biomimetic understanding of the modulation of ultrasound for medical and engineering purposes.
