The puzzle of Metazoan life history evolution: are feeding larvae always primitive? Most marine animals have a complex life-cycles with alternating pelagic larvae and benthic adults. An theory about animal life-history evolution states that feeding larvae are always primitive and larval feeding is lost but not gained. This hypothesis is based in part on studies on the 'classical' trochophore of marine worms such as Serpulidae, a group with both feeding and non-feeding larvae. We intend to establ ....The puzzle of Metazoan life history evolution: are feeding larvae always primitive? Most marine animals have a complex life-cycles with alternating pelagic larvae and benthic adults. An theory about animal life-history evolution states that feeding larvae are always primitive and larval feeding is lost but not gained. This hypothesis is based in part on studies on the 'classical' trochophore of marine worms such as Serpulidae, a group with both feeding and non-feeding larvae. We intend to establish a detailed phylogeny for Serpulidae and assess the evolution of larvae in the group. If feeding larvae are shown to be secondary this will raise doubts about established theories of animal evolution.Read moreRead less
Sound discrimination in embryos affects lifetime fitness. This project aims to investigate the role of prenatal sound discrimination on postnatal vocal learning and foraging breadth. The project expects to generate new knowledge in the area of neuroscience and psychology using an innovative approach to measure how embryos learn, and determine effects of prenatal vocal experience on the repertoire of postnatal behaviour. Expected outcomes include understanding biological mechanisms for effective ....Sound discrimination in embryos affects lifetime fitness. This project aims to investigate the role of prenatal sound discrimination on postnatal vocal learning and foraging breadth. The project expects to generate new knowledge in the area of neuroscience and psychology using an innovative approach to measure how embryos learn, and determine effects of prenatal vocal experience on the repertoire of postnatal behaviour. Expected outcomes include understanding biological mechanisms for effective learning across life stages that would be useful to develop novel approaches for non-invasive monitoring of embryonic cognition.Read moreRead less
Marine flatworm parasites of elasmobranchs: a unique model for experiments exploring invasion strategies, biology and specificity to help understand parasitism. Primitive parasites with simple life cycles from ancient hosts emphasise adaptations to parasitism. Experimental studies on live eggs and infective stages of different monogenean (flatworm) parasite species from the skin, gills and cloaca of southern fiddler rays will identify critical interactions early in parasite-host relationships t ....Marine flatworm parasites of elasmobranchs: a unique model for experiments exploring invasion strategies, biology and specificity to help understand parasitism. Primitive parasites with simple life cycles from ancient hosts emphasise adaptations to parasitism. Experimental studies on live eggs and infective stages of different monogenean (flatworm) parasite species from the skin, gills and cloaca of southern fiddler rays will identify critical interactions early in parasite-host relationships that determine whether or not parasitism occurs. Basic and applied benefits include: development of a tractable experimental system for studying parasite-host relationships; strategies to control parasites in public aquaria and aquaculture; profitable and exportable expertise; excellence and research training in basic parasitology; contributions to Australia's natural heritage collections.Read moreRead less
Capturing Proteus: 65 million years of ecosystem change revealed through evolution of Proteaceae in Australasia. By assessing past changes in the iconic Australian plant family Proteaceae, this research will show how the Australasian vegetation has responded to 65 million years of profound landscape and climate changes. This knowledge from the past will give important insights into how ecosystems can be expected to change under future climate scenarios.
Evolution, adaptation and resilience of Australian freshwater fishes. This project will integrate comparative ecological genomics (in the wild and in the lab), phenotypic data and spatially-explicit modelling approaches to assess adaptation and vulnerability of aquatic biodiversity to environmental change. It focuses on a family of Australian freshwater fishes that evolved in response to hydrological disturbance and shows contemporary patterns of biodiversity shaped by hydroclimatic variation an ....Evolution, adaptation and resilience of Australian freshwater fishes. This project will integrate comparative ecological genomics (in the wild and in the lab), phenotypic data and spatially-explicit modelling approaches to assess adaptation and vulnerability of aquatic biodiversity to environmental change. It focuses on a family of Australian freshwater fishes that evolved in response to hydrological disturbance and shows contemporary patterns of biodiversity shaped by hydroclimatic variation and anthropogenic pressures. The project expects to disclose a positive correlation between family-wide adaptive capacity and variance in ecological disturbance. This work will address fundamental and novel questions about factors shaping adaptation and resilience along naturally and anthropogenically disturbed ecosystems.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.
Developing best-practice approaches for restoring forest ecosystems that are resilient to climate change. Existing restoration practices for forests tend to rely on ad hoc rules of thumb that lack a firm scientific basis and risk failure due to climate change. The project will model biodiversity, genetic and growth performance data to develop best-practice restoration guidelines for forest ecosystems to enable them to become resilient to climate change and maximise biodiversity and carbon captur ....Developing best-practice approaches for restoring forest ecosystems that are resilient to climate change.
