eGenomics - Next generation biomonitoring of threatened species. DNA is the molecule of life and exists everywhere in the environment as a largely untapped source of information on evolution, biodiversity, and ecosystem health. Our overriding aim is to start mining that information to benefit threatened species. Based on optimized ancient DNA methods, powerful sequencing technology, whole genome analyses, and RNA profiling, we present a novel and holistic framework for genetic biomonitoring.

DNA is the molecule of life and exists everywhere in the environment as a largely untapped source of information on evolution, biodiversity, and ecosystem health. Our overriding aim is to start mining that information to benefit threatened species. Based on optimized ancient DNA methods, powerful sequencing technology, whole genome analyses, and RNA profiling, we present a novel and holistic framework for genetic biomonitoring. In two parallel model systems we will study corals and reptiles to improve environmental detection while simultaneously obtaining information on their population health. This will foster more efficient conservation of endangered species that are of tremendous importance to our marine and terrestrial ecosystems.Read moreRead less
Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspr ....Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspring changes over the lifespan of plants which retain their seeds for many years; at what age within-plant genetic variation is at a maximum as a guide to optimal fire management; and the extent that deleterious somatic mutations explain low seed set among long-lived species.Read moreRead less

Increasingly, large Australian multicentre research programs in biological and medical sciences have a genomics component that involves integration of biological information with sequencing data. The success of these research programs depends on rapid internet access to the research information by all participating scientists. The universal design of the proposed information management system means that it can be easily adapted to support a broad range of research programs. The development of this software program therefore has the potential to benefit research scientists, academics and students in many related fields, as well as the broader community, through enhancing research outcomes.Read moreRead less
Is restoration working? An ecological genetic assessment. This project aims to assess the success of restoration in terms of ecological and genetic viability for plant species in the Fitzgerald River–Stirling Range region of Western Australia, where significant investment is being made in restoring connectivity at a landscape scale. The project intends to compare reproductive output, pollinator behaviour, mating, genetic diversity and pollen dispersal in restored sites with those of undisturbed ....Is restoration working? An ecological genetic assessment. This project aims to assess the success of restoration in terms of ecological and genetic viability for plant species in the Fitzgerald River–Stirling Range region of Western Australia, where significant investment is being made in restoring connectivity at a landscape scale. The project intends to compare reproductive output, pollinator behaviour, mating, genetic diversity and pollen dispersal in restored sites with those of undisturbed natural vegetation. The project moves measures of restoration success beyond that of population establishment and survival to incorporate the evolutionary processes that provide long-term resilience, persistence and functional integration of restored populations into broader landscapes.Read moreRead less
Quantifying long-distance seed dispersal and its role in the metapopulation dynamics of plants with contrasting life histories. This work will contribute to the assessment of best fire-management practices, enabling land managers to compare current fire practices against those required for conservation of genetic resources. Our quantification of Long distance seed dispersal (LDD) among species with different life history attributes will be a major theoretical contribution to the fields of popula ....Quantifying long-distance seed dispersal and its role in the metapopulation dynamics of plants with contrasting life histories. This work will contribute to the assessment of best fire-management practices, enabling land managers to compare current fire practices against those required for conservation of genetic resources. Our quantification of Long distance seed dispersal (LDD) among species with different life history attributes will be a major theoretical contribution to the fields of population ecology and population genetics. LDD is also imperative if species are to survive the major shifts in climate projected under modelled climate change scenarios - species without effective LDD may have a greater probability of extinction due to climate change. Assessing LDD enables quantification of this significant aspect of the threat of climate change to biodiversity.Read moreRead less

Ancient genomics of Western Australian taxa to inform conservation management. The project aims to apply genomic approaches to infer the genetic health and evolutionary history of three threatened, iconic Western Australian taxa: black cockatoos, ghost bats and woylies. Genomic data provide a powerful lens through which to study species, but the applications of genomic techniques in conservation biology have been sparse. Effective restoration and conservation initiatives require an understanding ....Ancient genomics of Western Australian taxa to inform conservation management. The project aims to apply genomic approaches to infer the genetic health and evolutionary history of three threatened, iconic Western Australian taxa: black cockatoos, ghost bats and woylies. Genomic data provide a powerful lens through which to study species, but the applications of genomic techniques in conservation biology have been sparse. Effective restoration and conservation initiatives require an understanding of species' former population sizes, connectivity and biodiversity. The project seeks to elucidate the population genetic, phylogenetic, and conservation genetic parameters of the three species at the genomic level using DNA isolated from modern and ancient sources (eg museum skins and fossils). The information gained may inform conservation efforts for some of Australia’s endangered biota.Read moreRead less

This industry-driven project aims to assemble a strategic research alliance to generate and apply knowledge to a highly significant fisheries resource. It involves collaboration between the five major state government fisheries agencies in Australia, the New Zealand’s Crown Research Institute for seafood and two Australian labs with leadership in fish genetics and genomics. It expects to generate and integrate genomic, environmental and phenotypic datasets for snapper populations from across vast coastal regions of the two countries. The outcomes should substantially enhance intra- and inter-jurisdictional fisheries management and aquaculture initiatives, providing commercial, social and environmental benefits for many stakeholders.Read moreRead less
Control points in nitrogen uptake: enhancing the response of cereals to nitrogen supply and demand. Vast amounts of nitrogen fertiliser are applied to cereal crops to maintain yields. By uncovering what limits nitrogen uptake in cereals, this project will provide the scientific basis for improving nitrogen use efficiency and decreasing fertiliser use, with significant economic and environmental benefits.
Assessment of past biodiversity through DNA preserved in bulk bone. This project aims to make a unique study of fossils to determine how the composition and biodiversity of ecosystems have changed in response to anthropogenic influences. Fossil bones provide a window through which to study past environments and how they have changed, and the stories these fossils tell can be further enhanced by ancient DNA analyses. This project plans to use bulk bone metabarcoding where hundreds of low-value (f ....Assessment of past biodiversity through DNA preserved in bulk bone. This project aims to make a unique study of fossils to determine how the composition and biodiversity of ecosystems have changed in response to anthropogenic influences. Fossil bones provide a window through which to study past environments and how they have changed, and the stories these fossils tell can be further enhanced by ancient DNA analyses. This project plans to use bulk bone metabarcoding where hundreds of low-value (fragmented) bones are collectively ground together to provide a cost-effective genetic audit of fossil assemblages. Working on bone from across Oceania and south-east Asia, this project aims to provide a historical perspective on biodiversity. Understanding former ecosystem composition and extinction may facilitate effective restoration and conservation initiatives.Read moreRead less
Dispersal and persistence of large-seeded forest species under global environmental change. This project investigates how decline of a key seed disperser, the emu, due to global environmental change (fragmentation, fire regime change, human population growth, climate change) affects the persistence and migration potential of endemic SW Australian forest plant species. Results will inform approaches to ecosystem management and conservation
