Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and gene ....Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and genetics to address questions such as how and why ancestral macropods descended from the trees and evolved bipedal hopping, and the upper size limits of the kangaroo “body plan”. This should improve our understanding of the long-term effects of climate change on marsupials, and provide a test of key placental-based evolutionary models.Read moreRead less

Summary
Can species interactions drive diversification? Species interactions may drive the evolution of species diversity but we currently lack the empirical evidence to demonstrate conclusively how this occurs. Using a group of closely-related species native to Australia's rainforest, this study will test how species interactions drive the evolution of mating traits and the formation of new species.
Reconstructing the evolution of climatic tolerances in conifers. This project aims to trace the evolution of climate tolerance in conifers by combining evidence from fossils, phylogenies, physiology and mathematics. The project plans to use innovative methods to overcome the biases in methods currently used to trace evolutionary change. The project plans to integrate data from three sources: the global fossil record, new models of current climatic tolerances of conifers, and mathematical simulat ....Reconstructing the evolution of climatic tolerances in conifers. This project aims to trace the evolution of climate tolerance in conifers by combining evidence from fossils, phylogenies, physiology and mathematics. The project plans to use innovative methods to overcome the biases in methods currently used to trace evolutionary change. The project plans to integrate data from three sources: the global fossil record, new models of current climatic tolerances of conifers, and mathematical simulations of how and when methods of reconstructing ancestral ecology fail. The combined results should show how this important group of organisms has responded to past climate change and how they will respond in the future. It should also provide improved estimates of past terrestrial climates.Read moreRead less
Genetics of species differentiation and hybridisation in Eucalyptus. This project aims to use state-of-the-art genomic technologies to characterise genes and genomic regions important for speciation and adaptation in Australia’s iconic eucalypts, and study the importance of hybridisation between species, especially during range expansion and contraction. A major international effort has seen a eucalypt become the second forest tree genome sequenced. This project aims to link the expanding intern ....Genetics of species differentiation and hybridisation in Eucalyptus. This project aims to use state-of-the-art genomic technologies to characterise genes and genomic regions important for speciation and adaptation in Australia’s iconic eucalypts, and study the importance of hybridisation between species, especially during range expansion and contraction. A major international effort has seen a eucalypt become the second forest tree genome sequenced. This project aims to link the expanding international knowledge on the eucalypt genome to the evolutionary dynamics of wild populations in Australia to provide unprecedented insights into the nature of species and processes which have shaped their evolution. These insights may inform their breeding as well as their conservation and management in Australia.Read moreRead less
Identifying the genes and population histories that drive rapid adaptive change and speciation. This project will uncover the genetic variation and demographic histories that allow rapid adaptation and speciation in natural populations. It will leverage the powerful framework provided by Indo-Australian sea snakes, and new gene sequencing technologies, to reconstruct the evolutionary histories of genes, populations and species. Using this data, it will address inter-related key questions that ar ....Identifying the genes and population histories that drive rapid adaptive change and speciation. This project will uncover the genetic variation and demographic histories that allow rapid adaptation and speciation in natural populations. It will leverage the powerful framework provided by Indo-Australian sea snakes, and new gene sequencing technologies, to reconstruct the evolutionary histories of genes, populations and species. Using this data, it will address inter-related key questions that are critical to effective biodiversity conservation but have rarely been evaluated in the same taxon. It will address what genetic changes are involved in adaptive shifts and speciation, whether these originate de novo or from pre-existing variation and how gene flow and changes in population size promote or constrain adaptation and speciation.Read moreRead less
