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
Australia's mammalian carnivore diversity in space and time. To more effectively address the current extinction crisis we need to understand past diversity. This research program will comprehensively investigate the diversity of mammalian carnivores on three continents over geological time. Results will provide insight into whether the evolution of Australia's mammal carnivores differs fundamentally from those of other continents, as has often been suggested but not quantitatively demonstrated. ....Australia's mammalian carnivore diversity in space and time. To more effectively address the current extinction crisis we need to understand past diversity. This research program will comprehensively investigate the diversity of mammalian carnivores on three continents over geological time. Results will provide insight into whether the evolution of Australia's mammal carnivores differs fundamentally from those of other continents, as has often been suggested but not quantitatively demonstrated. Studies focused in the present are important, but often miss critical factors that can only be clarified through analyses with deep time perspectives. The findings will translate into an improved understanding of what makes Australia unique and better-informed decisions regarding wildlife management.Read moreRead less

Summary
Revealing the origin and early evolution of spiralian animal body plans. This project aims to reconstruct the early evolutionary history of the Spiralia, a megadiverse animal group that extends back 540 million years. Their oldest fossils represent some of the earliest known animals and can reveal much about the speed and magnitude of evolution during the Cambrian Explosion, when most animal groups rapidly appeared. This project expects to generate new knowledge on the origin and radiation of so ....Revealing the origin and early evolution of spiralian animal body plans. This project aims to reconstruct the early evolutionary history of the Spiralia, a megadiverse animal group that extends back 540 million years. Their oldest fossils represent some of the earliest known animals and can reveal much about the speed and magnitude of evolution during the Cambrian Explosion, when most animal groups rapidly appeared. This project expects to generate new knowledge on the origin and radiation of some of the first animal body plans to better understand the early history of complex life. Anticipated outcomes and benefits include a new macroevolutionary framework for spiralians, novel approaches to studying invertebrate fossils, and highlighting the scientific importance of Australia’s natural heritage.Read moreRead less
Survival stategies and dynamics of stromatolite-associated microbial populations. Biogenic stromatolites are formed by the accretion of carbonates and entrapment of sediments by benthic cyanobacteria, algae and other microorganisms. Stromatolites have been present on Earth for more than three billion years and the biogeochemical processes involved in their formation are indicators of the earliest life on this planet. The applicant proposes to study, at the level of molecular genetics, the divers ....Survival stategies and dynamics of stromatolite-associated microbial populations. Biogenic stromatolites are formed by the accretion of carbonates and entrapment of sediments by benthic cyanobacteria, algae and other microorganisms. Stromatolites have been present on Earth for more than three billion years and the biogeochemical processes involved in their formation are indicators of the earliest life on this planet. The applicant proposes to study, at the level of molecular genetics, the diversity of stromatolite-associated microorganisms. The defined microbial populations will be correlated with the prevailing environmental conditions to elucidate the effect of biological and physical factors in determining stromatolite structure.Read moreRead less
Understanding the evolutionary tempo and significance of the first animals through exceptional fossil preservation. This project will shed new light on the origins and early evolutionary history of the first complex marine animals that appeared over half a billion years ago. Extraordinarily preserved fossils, including soft tissues, from South Australia will highlight the rapid anatomical innovation that occurred during this crucial phase in the history of life.
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.
Determining the relative roles of dispersal and vicariance in the assembly of the New Zealand fauna. New fossils from New Zealand's St Bathans Fauna (19-16 million years) will revolutionise our understanding of the shared biodiversity and evolutionary history of New Zealand and Australia through the first views of the origin and evolution of major Gondwanan groups including frogs, crocodiles, birds and bats on the now mostly-drowned continent Zealandia.
New Riversleigh: Bridging chasms in the Neogene of Australia. This project aims to investigate the evolution of Australia’s animals in the late Miocene, 10 - 5 million years ago. The team’s discovery of a remote fossil field west of and larger than the Riversleigh World Heritage Area opens a window into Australia’s past, linking those of Australia's older lush rainforest communities to those of its drier, more modern habitats. Radiometric dates indicate that sediments in this vast area are late ....New Riversleigh: Bridging chasms in the Neogene of Australia. This project aims to investigate the evolution of Australia’s animals in the late Miocene, 10 - 5 million years ago. The team’s discovery of a remote fossil field west of and larger than the Riversleigh World Heritage Area opens a window into Australia’s past, linking those of Australia's older lush rainforest communities to those of its drier, more modern habitats. Radiometric dates indicate that sediments in this vast area are late Miocene in age. This project will reveal how Australia’s wildlife responded to one of the world’s biggest climate changes and help better anticipate what will be required to ensure its survival into the future. Benefits include enhanced understanding about long-term biota/climate interactions and significant additions to Australia’s unique, internationally significant palaeontological artefacts.Read moreRead less
Dawn of the age of mammals in Australia: foundations for an island biota. This project aims to fill a profound gap in knowledge about the origins of the modern fauna on the island continent Australia. It will augment Australia’s national natural heritage, enhance international research collaboration, and provide critical baseline data for complementary research in biology, geology, geography and climatology. End users of this project include primary, secondary, tertiary and public education sect ....Dawn of the age of mammals in Australia: foundations for an island biota.
