The genetic architecture of colour polymorphism and speciation. Speciation, the process by which populations diverge and become distinct, is the engine that drives biodiversity and Darwin's 'mystery of mysteries'. Speciation is accelerated in species with multiple, discrete, coexisting colour forms; yet the genetic mechanisms underpinning this pattern are not known. This project aims to identify the genes underlying different colour forms and how they are distributed across the genome. The proj ....The genetic architecture of colour polymorphism and speciation. Speciation, the process by which populations diverge and become distinct, is the engine that drives biodiversity and Darwin's 'mystery of mysteries'. Speciation is accelerated in species with multiple, discrete, coexisting colour forms; yet the genetic mechanisms underpinning this pattern are not known. This project aims to identify the genes underlying different colour forms and how they are distributed across the genome. The project plans to test the prediction that these same areas of the genome show marked divergence between lineages that are in the process of becoming distinct species. Doing so may contribute significantly to our understanding of speciation, underlying genetic mechanisms, and genes generating colour variation in vertebrates.Read moreRead less

Summary
Integrating ecology and evolution: how does sexual selection affect population fitness and extinction? Improving our understanding of population fitness could produce important new advances in evolutionary and conservation biology. Sexual selection has been proposed to both help and harm population fitness, but unfortunately these opposing effects have been studied in isolation.

Improving our understanding of population fitness could produce important new advances in evolutionary and conservation biology. Sexual selection has been proposed to both help and harm population fitness, but unfortunately these opposing effects have been studied in isolation. This project will develop new theory to resolve confusion over the definition of population fitness and its relationship with sexual selection. It also proposes ambitious experimental evolution and quantitative genetic studies that will empirically measure the net effect of sexual selection on population fitness and extinction. This project aims to catalyse a change in the study of population fitness and address a conspicuous gap in contemporary evolutionary biology.Read moreRead less
Evolution in action or the demise of iconic Australian flora? The project aims to investigate the evolutionary history and conservation status of a group of closely related Grevillea species, in the light of increasing pressure from landscape modification. This project will incorporate leading methodologies for massively parallel sequencing, pollinator preference and breeding capacity in order to detect the patterns and processes underpinning divergence in widely distributed species. A phylogene ....Evolution in action or the demise of iconic Australian flora? The project aims to investigate the evolutionary history and conservation status of a group of closely related Grevillea species, in the light of increasing pressure from landscape modification. This project will incorporate leading methodologies for massively parallel sequencing, pollinator preference and breeding capacity in order to detect the patterns and processes underpinning divergence in widely distributed species. A phylogenetic framework will provide the evolutionary relationships among taxa. This project is expected to inform requirements for long-term species persistence and, for threatened species within the group, guide the decision making of biodiversity managers as to what actions are required and where best to invest limited funds.Read moreRead less

Summary
Developing predictions of extinction risk for tropical arthropods in the face of global environmental change. Developing knowledge of the characteristics that make species especially at risk of extinction is critical in order to limit the extent of future biodiversity losses. This project uses the fossil record of extinctions on islands in order to develop a better understanding of the processes that drive species to extinction.

Interactions of sexual selection & ecological divergence during speciation. Understanding the processes driving speciation is fundamental to understanding how biodiversity is generated. The two main forces underlying speciation, ecological divergence and sexual selection, are well characterised, yet how they interact during the speciation process is remarkably poorly understood.

Understanding the processes driving speciation is fundamental to understanding how biodiversity is generated. The two main forces underlying speciation, ecological divergence and sexual selection, are well characterised, yet how they interact during the speciation process is remarkably poorly understood. This project aims to test hypotheses regarding how ecological divergence and sexual selection interact during speciation, from its inception to its completion. In doing so, this research aims to identify genomic regions underlying divergence in colour patterns, which are important for ecological and sexual interactions. Consequently, this project will significantly enhance our understanding of ecological and genetic mechanisms underlying speciation.Read moreRead less
Faunal responses to environmental change and isolation on an Australian land-bridge island. Establishing how faunas responded to past isolation and environmental changes offers great potential for predicting long-term impacts of habitat fragmentation. By combining novel methods we will track extinction rates, diet and body-size shifts on Kangaroo Island, the only known land-bridge island with a fossil record spanning the past 100,000 years.

Summary
The biodiversity consequences of evolutionary innovation. This project aims to increase knowledge of how evolutionary innovations affect biodiversity. This project will focus on a classic example of evolutionary innovation, the specialized throat jaws found in many fish groups, including damselfishes, wrasses, and cichlids. These unique jaws may explain why these fish groups contain so many species and are such successful invasive species in Australia and elsewhere. This project proposes an inte ....The biodiversity consequences of evolutionary innovation. This project aims to increase knowledge of how evolutionary innovations affect biodiversity. This project will focus on a classic example of evolutionary innovation, the specialized throat jaws found in many fish groups, including damselfishes, wrasses, and cichlids. These unique jaws may explain why these fish groups contain so many species and are such successful invasive species in Australia and elsewhere. This project proposes an integrative combination of methods and functional experiments to reveal the biodiversity consequences of evolutionary innovation. It will also enhance Australian biosecurity through the production of new ways to assess invasion risk from aquaculture and aquarium trade species.Read moreRead less
Peopling educational policy: realising the new Australian English and mathematics curricula. Implementation of Australian curricula in English and mathematics provides an opportunity for school systems to re-examine practice. This project will identify resources and teacher learning opportunities needed to facilitate implementation of these curricula and use findings to develop interventions identified as likely to optimise implementation.

Classrooms remain the principal site of institutionalised learning. Their cultural specificity poses challenges for international comparative research. New approaches are needed. Internationally, our educational theories, research and descriptions of practice are framed in English, which names some aspects of the classroom, but ignores key aspects named in other languages. This limits our capacity to access, connect and adapt the wisdom of other cultures. The Lexicon Project will initiate cross-cultural dialogue to identify pedagogical terms from selected Asian and European educational communities and use these as analytical tools to categorise, interrogate and enrich our classroom practice, classroom research, and educational theorising.Read moreRead less
