Restoring amphibian populations in chytrid-impacted landscapes. This project aims to address an outstanding problem in wildlife disease ecology: how can we enable susceptible amphibians to persist in the face of the chytrid pathogen, which has devastated amphibian biodiversity? This project expects to generate new knowledge by experimentally trialling two highly promising interventions: immunising animals and creating disease refugia through simple habitat manipulations. Outcomes of this project ....Restoring amphibian populations in chytrid-impacted landscapes. This project aims to address an outstanding problem in wildlife disease ecology: how can we enable susceptible amphibians to persist in the face of the chytrid pathogen, which has devastated amphibian biodiversity? This project expects to generate new knowledge by experimentally trialling two highly promising interventions: immunising animals and creating disease refugia through simple habitat manipulations. Outcomes of this project include a framework for predicting how interventions might enable host-pathogen coexistence. This project should provide significant benefits including enhanced understanding of wildlife disease dynamics that will pave the way for interventions to restore amphibian biodiversity in chytrid-impacted landscapes.Read moreRead less
How isolated is Antarctica? Assessing past and present plant colonisations. The project aims to assess how biologically isolated Antarctica is by discovering how, when and where natural colonisations of the continent have occurred. The research will focus on mosses, the dominant plant group in the Antarctic. genomic tools will be combined with environmental, spatial, and ecological data to assess mechanisms and directions of dispersal to and around Antarctica, and to predict areas most likely to ....How isolated is Antarctica? Assessing past and present plant colonisations. The project aims to assess how biologically isolated Antarctica is by discovering how, when and where natural colonisations of the continent have occurred. The research will focus on mosses, the dominant plant group in the Antarctic. genomic tools will be combined with environmental, spatial, and ecological data to assess mechanisms and directions of dispersal to and around Antarctica, and to predict areas most likely to be colonised in the future. This will help understand the processes underpinning the evolution and diversity of Antarctic species, and the vulnerability and adaptability of Antarctic ecosystems. Read moreRead less
Evolution of Australia's globally unique hotspot of floral diversity. Australia has a globally recognised biodiversity hotspot, the southwest of Western Australia, but this unique eucalypt-dominated flora is threatened. This project will gain new insights into the evolutionary processes that generate and maintain such diversity, their vulnerability; and how the iconic eucalypts came to dominate the Australian landscape.
Evolutionary and conservation implications of extreme predation on female endangered swift parrots. Introduced predators have wrought havoc on native species worldwide. The impacts on prey species may be exacerbated when they are subject to sex-selective predation, leading to biased adult sex ratios. In Tasmania, introduced sugar gliders are killing up to 100 per cent of nesting female endangered swift parrots at many of their breeding sites. This project integrates evolutionary theory, state-of ....Evolutionary and conservation implications of extreme predation on female endangered swift parrots. Introduced predators have wrought havoc on native species worldwide. The impacts on prey species may be exacerbated when they are subject to sex-selective predation, leading to biased adult sex ratios. In Tasmania, introduced sugar gliders are killing up to 100 per cent of nesting female endangered swift parrots at many of their breeding sites. This project integrates evolutionary theory, state-of-the-art population meta-models and field experiments to: achieve practical conservation outcomes; assess the evolutionary and ecological consequences of sex-selective predation on population dynamics; and determine whether swift parrots are modifying their behaviour adaptively through learned or genetic change.

Evolutionary history and conservation of an iconic Australian plant group. This project aims to strengthen biodiversity conservation using evolutionary biology. By using new DNA sequencing technologies the project aims to reconstruct the evolutionary history of the diverse and ecologically important plant family Proteaceae. This will be used to discover how past environmental changes have produced the biodiversity we see today, and forecast likely future changes to biodiversity under expected r ....Evolutionary history and conservation of an iconic Australian plant group. This project aims to strengthen biodiversity conservation using evolutionary biology. By using new DNA sequencing technologies the project aims to reconstruct the evolutionary history of the diverse and ecologically important plant family Proteaceae. This will be used to discover how past environmental changes have produced the biodiversity we see today, and forecast likely future changes to biodiversity under expected rapid environmental change. The key outcome will be a new methodology for a predictive, forward-looking conservation science that accounts explicitly for the dynamic, evolving nature of biodiversity. The key benefit will be a more robust scientific basis for strategic allocation of limited conservation resources.Read moreRead less
Global patterns of mammalian biodiversity loss over the last 50,000 years. Wild mammals have experienced major population losses and extinctions in recent centuries, but their communities had already suffered from widespread losses during the Pleistocene. Existing literature has focused on documenting individual extinctions or continental-scale patterns. This project aims to show how biodiversity loss played out at the local scale around the world. It will use palaeontological and zooarchaeologi ....Global patterns of mammalian biodiversity loss over the last 50,000 years. Wild mammals have experienced major population losses and extinctions in recent centuries, but their communities had already suffered from widespread losses during the Pleistocene. Existing literature has focused on documenting individual extinctions or continental-scale patterns. This project aims to show how biodiversity loss played out at the local scale around the world. It will use palaeontological and zooarchaeological data to show how losses varied in space, how population sizes changed, and how species attributes such as rarity and body size related to loss. The world of mammals has become more homogeneous as biodiversity has declined. The challenge is to show how that happened across space and time.

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
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
Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project wi ....Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project will provide a new, yet crucial, perspective on how and why diseases spread. Our discoveries will help understand and manage the burden of infectious diseases from parasites in and beyond our cities and across the human-wildlife interface; essential for improving human and wildlife health in an increasingly urbanised Australia.Read moreRead less

This project aims to understand flying-fox movement ecology from individual navigation through to population redistribution. Understanding movement across spatiotemporal scales is a goal of movement research. Grey-headed flying-foxes are mobile, and advances in tracking technology make them ideal for studying movement across scales. This project will determine how flying foxes navigate, and integrate this with drivers of their movement to understand their movement ecology by using methods that integrate experimental manipulation with telemetry, Doppler radar and analytical techniques. This is expected to develop much-needed management strategies that incorporate an understanding of movement.Read moreRead less
