Summary
Exploring new territory in climatic adaptation research: integrating molecular genetics with species' thermal tolerance limits. Predicting species' responses to environmental change requires mechanistic links between whole-organism physiological stress responses and underlying cellular mechanics. This project integrates cutting-edge methods in molecular and evolutionary genetics to probe species' responses to environmental change in the context of a warming environment.

Summary
Using biological invasions to understand evolutionary processes. The invasion of cane toads through Australia has been devastating for many native species, but created opportunities for others. The rapid evolutionary responses stimulated by toad invasion provide a uniquely powerful model system with which to explore the broader question of how species adapt to novel challenges.
How do Microbes Grow in High Salt at Very Cold Temperatures. The proposed research aims to define mechanisms of survival and speciation that underpin the capacity of a novel group of Antarctic microorganisms to evolve dominance in their very cold (-20 degrees Celsius) and very salty environment. Most (~85 per cent) of the Earth's biosphere is cold (<5 degrees Celsius), and yet contains a rich diversity of microorganisms of which we know little. The uniqueness and sensitivity of Antarctica partic ....How do Microbes Grow in High Salt at Very Cold Temperatures. The proposed research aims to define mechanisms of survival and speciation that underpin the capacity of a novel group of Antarctic microorganisms to evolve dominance in their very cold (-20 degrees Celsius) and very salty environment. Most (~85 per cent) of the Earth's biosphere is cold (<5 degrees Celsius), and yet contains a rich diversity of microorganisms of which we know little. The uniqueness and sensitivity of Antarctica particularly demands that we rapidly improve our understanding of its biology. The discoveries made could provide fundamental insight about speciation - processes controlling which life forms that colonise the planet.Read moreRead less
Who's calling? Understanding and exploiting signalling system ecology to improve success in trapping cane toads. This project has five major national and community benefits for Australia. It will: 1. provide a much-needed control option for a major pest, 2. actually remove many toads during the course of the study, through trapping at various locations around Australia, 3. support an Australian small business by providing research outcomes that will enable it to develop and market a highly desi ....Who's calling?

It will: 1. provide a much-needed control option for a major pest, 2. actually remove many toads during the course of the study, through trapping at various locations around Australia, 3. support an Australian small business by providing research outcomes that will enable it to develop and market a highly desired product, and 4. provide high level, postgraduate training in science. This project directly addresses the National Research Priority goal safeguarding Australia, protecting Australia from invasive … pests, because it will generate new technologies useful for controlling an invasive species.Read moreRead less
Targeted gene flow for conservation. This project aims to develop targeted gene flow as a broad conservation strategy, exploiting natural geographic variation to achieve conservation outcomes. Geographic variation and local adaptation are ubiquitous within species, but conservation managers do not use this heritable variation. The project will develop decision tools to address when to time a targeted gene flow action, and where to source appropriate genetic variation. As case studies, the projec ....Targeted gene flow for conservation. This project aims to develop targeted gene flow as a broad conservation strategy, exploiting natural geographic variation to achieve conservation outcomes. Geographic variation and local adaptation are ubiquitous within species, but conservation managers do not use this heritable variation. The project will develop decision tools to address when to time a targeted gene flow action, and where to source appropriate genetic variation. As case studies, the project will try to use targeted gene flow to halt the invasion of the cane toad in northern Australia and reverse the decline of northern quolls.Read moreRead less
Peripheral isolates as hotbeds of adaptive diversity. This project uses cutting edge molecular technology and spatial analyses to predict the location of diversity relevant to managing the impact of climate change. Knowledge generated in this project will open the door to the informed use of genetic translocation in efforts to kerb expected biodiversity losses.
Understanding when biocontrol and enemy release affect plant populations. This project aims to determine when introduced species escape from their natural enemies, and when biocontrol efforts succeed. Enemy release and biocontrol are key to our understanding and management of invasions. However there has never been a broad quantitative assessment of the circumstances under which biocontrol and enemy release affect introduced populations. This project will use a combination of meta-analyses and i ....Understanding when biocontrol and enemy release affect plant populations. This project aims to determine when introduced species escape from their natural enemies, and when biocontrol efforts succeed. Enemy release and biocontrol are key to our understanding and management of invasions. However there has never been a broad quantitative assessment of the circumstances under which biocontrol and enemy release affect introduced populations. This project will use a combination of meta-analyses and international field studies to address this knowledge gap. Expected outcomes include a better understanding of the factors that facilitate biological invasions, and improved success of biocontrol agents.Read moreRead less
Natural selection and the Tasmanian devil. This project aims to explain evolution of immune capabilities in response to disease threats in the wild by assessing the immune adaptive capabilities of Tasmanian devils in response to facial tumour disease. It plans to determine how the expression of immune genes differs between wild and captive populations.

It plans to determine how the expression of immune genes differs between wild and captive populations. The project will combine immunology, epidemiology and evolutionary biology, to understand the role of host genetic and phenotypic adaptations to disease threats. The project will assist in the development of diagnostic tools for managing this and other threatened species and for screening disease resistance markers across wild and captive insurance populations.Read moreRead less

Summary
Diet, variance and individual variability in life-history. This project aims to provide biologists with novel statistical tools that will shift analytical paradigms. In many species, dietary restrictions increase average lifespan, and affect average rates of growth and reproduction, also known as ‘life history’. The use of recently developed tools has shown that individual variability in life history also appears to increase under dietary restrictions. This project will explore the effects of di ....Diet, variance and individual variability in life-history. This project aims to provide biologists with novel statistical tools that will shift analytical paradigms. In many species, dietary restrictions increase average lifespan, and affect average rates of growth and reproduction, also known as ‘life history’. The use of recently developed tools has shown that individual variability in life history also appears to increase under dietary restrictions. This project will explore the effects of diet composition on variability in life-history traits, and the factors driving this variation. This is expected to improve the prediction of the effects of changing nutritional environments.Read moreRead less
Preventing and reversing population declines of northern quolls. This project seeks to develop novel effective strategies to halt and reverse declines in northern quolls by improving their ‘toad-smart’ behaviour. The spread of cane toads threaten northern quolls, which are marsupial predators. We cannot halt the toad invasion, but we can train quolls not to eat cane toads. Trained quolls can survive long term in toad-infested landscapes, and their offspring can learn not to eat toads. This proje ....Preventing and reversing population declines of northern quolls.

Trained quolls can survive long term in toad-infested landscapes, and their offspring can learn not to eat toads. This project builds on this work by focusing on cultural and genetic transmission of toad-smart behaviour. The project could save numerous quoll populations from extinction.Read moreRead less
