BIODIVERSITY AND EVOLUTION OF THE AUSTRALIAN FLORA

1995 / 96


Leader

Jeremy BURDON (06) 246 5084

Goal

To determine the biological diversity, distribution, relationships and genetic systems of native genera and species of the Australian flora.

Description

The Australian National Herbarium is a centre for biosystematic and phylogenetic studies of the Australian flora providing the core knowledge needed for the effective conservation of Australia's natural communities and the utilisation of its plants as genetic resources. Our studies are multidisciplinary, featuring a central core emphasis on morphological features that is enhanced through the extensive use of other approaches including anatomy, cytology, phytochemistry, molecular analysis and breeding system studies. Efforts are being made to understand the interaction between the Australian flora and selected groups of the microbial flora. Currently these studies are centred on assessing the development of parasitic and symbiotic relationships and the importance of these in generating and maintaining diversity within the Australian flora. Through the compilation and analysis of the data obtained we attempt to provide answers to the following fundamental questions: what are the taxa represented: what are their geographic and ecological distributions: what are their evolutionary and biogeographic relationships? The Australian National Herbarium also functions as a resource centre for the Flora of Australia project maintained by the Australian Biological Resources Study.
