Global differentiation of the conifer flora. Conifers are among the most widely recognised and well-loved group of plants. This project will place a global perspective on the evolutionary significance of the southern conifers. Furthermore conifers such as the Wollemi Pine, bunyas, kauris and huon pine are of considerable ecotourism value, and this project will provide a basis for interpretation of these important plants.
Drought and death: past, present and future survival limits in the Australian vegetation landscape. Science cannot predict the point at which water stress becomes lethal for plants. This research into plant water transport aims to find a new way to understand whether plant species will die or adapt to a future drier climate.
Australia's Distinctive Succulent Flora. The project plans to investigate why Australia, the driest vegetated continent, has no landscape dominated by large succulents but nevertheless supports a distinctive, diverse and widespread succulent flora. Focusing on terrestrial succulents and epiphytic orchids, the project plans to explore the evolution, assembly and biodiversity of Australia’s succulent flora, evaluating the roles of genetic composition, photosynthetic physiology, aridity, fire, soil ....Australia's Distinctive Succulent Flora. The project plans to investigate why Australia, the driest vegetated continent, has no landscape dominated by large succulents but nevertheless supports a distinctive, diverse and widespread succulent flora. Focusing on terrestrial succulents and epiphytic orchids, the project plans to explore the evolution, assembly and biodiversity of Australia’s succulent flora, evaluating the roles of genetic composition, photosynthetic physiology, aridity, fire, soil nutrients and salinity in its historical expansion, and assessing the resilience of the assemblages to changing climate. Of particular interest will be how the most water-use efficient type of photosynthesis, crassulacean acid metabolism, is expressed across the succulent landscape.Read moreRead less
Evolution of vascular tissue in land plants. This project will investigate genetic mechanisms of secondary cell wall thickening in a new genetic model representing an ancient plant lineage. This research will reveal the evolutionary origin of plant vascular tissue; a significant innovation that allowed increased size of plants and the origin of wood.

Summary
Sydney basin multi-purpose spectral analysis facility for evolutionary and ecological studies. This near infrared spectroscopy facility at The University of New South Wales will serve the Sydney area biological research community. Near infrared spectroscopy provides quick and robust estimates of key properties of animal and plant tissues, such as age, species and chemical composition.
A biological basis for the efficient breeding of native plants for export markets: a case study with the Australian Goodeniaceae. The native plant family Goodeniaceae exhibits enormous potential for the world potted-plant trade. To provide vital biological information for the efficient breeding of these plants, we will (i) determine the molecular evolutionary relationships of species, (ii) assess chromosomal variation within and among species, (iii) characterise mating patterns in natural popul ....A biological basis for the efficient breeding of native plants for export markets: a case study with the Australian Goodeniaceae. The native plant family Goodeniaceae exhibits enormous potential for the world potted-plant trade. To provide vital biological information for the efficient breeding of these plants, we will (i) determine the molecular evolutionary relationships of species, (ii) assess chromosomal variation within and among species, (iii) characterise mating patterns in natural populations using DNA fingerprinting for paternity analysis, (iv) develop techniques to overcome barriers to wide crossing, and (v) use DNA fingerprinting for the rapid identification of artificial hybrids. Expected outcomes are an understanding of evolution and mating in the Goodeniaceae and the efficient development of horticulturally significant materialRead moreRead less
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.
Molecular phylogeny and biodiversity of the plant family Rutaceae: evidence for Australian-New Caledonian biogeography. The results will contribute biological evidence for geological models of the evolution of New Caledonia and the Southwest Pacific region. Analyses will also contribute to improvement of methods and data interpretation in the field of historical biogeography. The molecular phylogeny will be the foundation for a new predictive classification of Australian Rutaceae at the level ....Molecular phylogeny and biodiversity of the plant family Rutaceae: evidence for Australian-New Caledonian biogeography. The results will contribute biological evidence for geological models of the evolution of New Caledonia and the Southwest Pacific region. Analyses will also contribute to improvement of methods and data interpretation in the field of historical biogeography. The molecular phylogeny will be the foundation for a new predictive classification of Australian Rutaceae at the level of tribes and genera. Improved phylogenetic classification underpins the delivery of biodiversity research, goods and services in Australia. Outcomes of improved taxonomy include species identification for ecological studies, identification of rare species, geographic areas of high conservation value and plants for horticulture.Read moreRead less
Developing biogeographic know-how: Improving species divergence and dispersal estimations to examine geological and climatic evolutionary drivers. Anthropogenic activity over the last 150 years is now dramatically changing our global climate and ecosystems. The impact on biodiversity is already evident, and large-scale floral and faunal extinctions are predicted. This study unites a cohort of international experts in an interdisciplinary team to develop new molecular and mathematical methods to ....Developing biogeographic know-how: Improving species divergence and dispersal estimations to examine geological and climatic evolutionary drivers. Anthropogenic activity over the last 150 years is now dramatically changing our global climate and ecosystems. The impact on biodiversity is already evident, and large-scale floral and faunal extinctions are predicted. This study unites a cohort of international experts in an interdisciplinary team to develop new molecular and mathematical methods to expand our fundamental knowledge on how geological and global climate change have affected our world's species components and ecosystems in the past. This research is of environmental significance and global importance as it will improve our ability to predict how species behave under future predicted climate scenarios.Read moreRead less
A predictive phylogenetic classification for Australian acacias and their tropical legume relatives worldwide. The results of this project will provide the foundation for a new predictive classification of Australian acacias and their relatives, among tropical legumes. Improved phylogenetic classification will underpin the delivery of biodiversity research, goods and services in Australia and neighbouring tropical countries. Outcomes of improved taxonomy include species identification and spec ....A predictive phylogenetic classification for Australian acacias and their tropical legume relatives worldwide. The results of this project will provide the foundation for a new predictive classification of Australian acacias and their relatives, among tropical legumes. Improved phylogenetic classification will underpin the delivery of biodiversity research, goods and services in Australia and neighbouring tropical countries. Outcomes of improved taxonomy include species identification and species selection in various industries and environmental programs. Acacias and legumes are used in agro-forestry, as shade trees for crops, fuel wood, stock feed, nitrogen fixation, planting for land reclamation in arid and salinity-affected areas, and as new plantation timber products.
