Phenotypic plasticity and plant water use in a changing climate: a multi-species, multi-site investigation. Plants are highly responsive to the conditions under which they grow, but the combination of conditions they experience will be altered under climate change. This research into plant responses to the novel environments posed by climate change will examine plasticity in water-use-traits to better predict native plant tolerance of climate change.
Diversification and conservation of Australian frogs. Australia's 216 known species of frogs are exceptionally diverse, 98 per cent are found nowhere else in the world and many of them are in trouble. This project will test ideas concerning the tempo of Australian frog diversification, identify previously cryptic new species and provide information critical to the conservation of Australia's declining frogs.
Testing the links between ecological processes and evolutionary radiations. This project aims to apply recent analytical advances to massive databases of the phylogeny and spatial distributions of mammals, birds and plants, to explore the role of small-scale ecological processes in generating large-scale macroevolutionary patterns. The processes involved in generating large-scale patterns of biodiversity are still not fully understood, but large new biodiversity databases and recent advances in ....Testing the links between ecological processes and evolutionary radiations. This project aims to apply recent analytical advances to massive databases of the phylogeny and spatial distributions of mammals, birds and plants, to explore the role of small-scale ecological processes in generating large-scale macroevolutionary patterns. The processes involved in generating large-scale patterns of biodiversity are still not fully understood, but large new biodiversity databases and recent advances in analytical methods put us in a good position to make significant progress. By integrating two separate research fields, community ecology and macroevolution, this project aims to make a significant contribution to biodiversity theory, and help to develop a more robust scientific foundation for long-range, process-based conservation planning.Read moreRead less

Summary
Bayesian Hierarchical Model for Biogeography. Species Distribution Models (SDMs) are crucial tools for conservation and planning, but they assume that environmental variables (e.g. temperature) are the only controls on distributions, when historical factors, like dispersal limitation and phylogenetic niche conservatism, are also important. A Bayesian Hierarchical Model (BHM) will be constructed to jointly estimate dispersal history, niche evolution, and present-day SDMs for each species in a cla ....Bayesian Hierarchical Model for Biogeography. Species Distribution Models (SDMs) are crucial tools for conservation and planning, but they assume that environmental variables (e.g. temperature) are the only controls on distributions, when historical factors, like dispersal limitation and phylogenetic niche conservatism, are also important. A Bayesian Hierarchical Model (BHM) will be constructed to jointly estimate dispersal history, niche evolution, and present-day SDMs for each species in a clade. BHMs will be tested against traditional SDMs using Australian clades (e.g. frogs) and simulations. BHMs will advance scientific understanding of how species and biogeography coevolve and provide practical improvements in predictions for species that are rare, data-poor, or in changed climates.Read moreRead less
