I Is the Sunda-Sahul Floristic Exchange Ongoing?
Is the Sunda-Sahul floristic exchange ongoing? A study of distributions, functional traits, climate and landscape genomics to investigate the invasion in Australian rainforests By Jia-Yee Samantha Yap Bachelor of Biotechnology Hons. A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2018 Queensland Alliance for Agriculture and Food Innovation i Abstract Australian rainforests are of mixed biogeographical histories, resulting from the collision between Sahul (Australia) and Sunda shelves that led to extensive immigration of rainforest lineages with Sunda ancestry to Australia. Although comprehensive fossil records and molecular phylogenies distinguish between the Sunda and Sahul floristic elements, species distributions, functional traits or landscape dynamics have not been used to distinguish between the two elements in the Australian rainforest flora. The overall aim of this study was to investigate both Sunda and Sahul components in the Australian rainforest flora by (1) exploring their continental-wide distributional patterns and observing how functional characteristics and environmental preferences determine these patterns, (2) investigating continental-wide genomic diversities and distances of multiple species and measuring local species accumulation rates across multiple sites to observe whether past biotic exchange left detectable and consistent patterns in the rainforest flora, (3) coupling genomic data and species distribution models of lineages of known Sunda and Sahul ancestry to examine landscape-level dynamics and habitat preferences to relate to the impact of historical processes. First, the continental distributions of rainforest woody representatives that could be ascribed to Sahul (795 species) and Sunda origins (604 species) and their dispersal and persistence characteristics and key functional characteristics (leaf size, fruit size, wood density and maximum height at maturity) of were compared.

Ecology of Proteaceae with Special Reference to the Sydney Region
951 Ecology of Proteaceae with special reference to the Sydney region P.J. Myerscough, R.J. Whelan and R.A. Bradstock Myerscough, P.J.1, Whelan, R.J.2, and Bradstock, R.A.3 (1Institute of Wildlife Research, School of Biological Sciences (A08), University of Sydney, NSW 2006; 2Department of Biological Sciences, University of Wollongong, NSW 2522; 3Biodiversity Research and Management Division, NSW National Parks & Wildlife Service, PO Box 1967, Hurstville, NSW 1481) Ecology of Proteaceae with special reference to the Sydney region. Cunninghamia 6(4): 951–1015. In Australia, the Proteaceae are a diverse group of plants. They inhabit a wide range of environments, many of which are low in plant resources. They support a wide range of animals and other organisms, and show distinctive patterns of distribution in relation to soils, climate and geological history. These patterns of distribution, relationships with nutrients and other resources, interactions with animals and other organisms and dynamics of populations in Proteaceae are addressed in this review, particularly for the Sydney region. The Sydney region, with its wide range of environments, offers great opportunities for testing general questions in the ecology of the Proteaceae. For instance, its climate is not mediterranean, unlike the Cape region of South Africa, south- western and southern Australia, where much of the research on plants of Proteaceae growing in infertile habitats has been done. The diversity and abundance of Proteaceae vary in the Sydney region inversely with fertility of habitats. In the region’s rainforest there are few Proteaceae and their populations are sparse, whereas in heaths in the region, Proteaceae are often diverse and may dominate the canopy.

Biodiversity Summary: Wet Tropics, Queensland
Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations.

Biodiversity Summary for NRM Regions Guide to Users Background What is the summary for and where does it come from? This summary has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. It highlights important elements of the biodiversity of the region in two ways: • Listing species which may be significant for management because they are found only in the region, mainly in the region, or they have a conservation status such as endangered or vulnerable. • Comparing the region to other parts of Australia in terms of the composition and distribution of its species, to suggest components of its biodiversity which may be nationally significant. The summary was produced using the Australian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA.

Rainforests in the South Pacific hold a considerable amount of plant diversity, with rates of species endemism >80% in some countries. This diversity is rapidly disappearing under pressure from logging, clearing for agriculture or mining, introduced pests and diseases and other anthropogenic sources. Ex situ conservation techniques offer a means to limit the loss of plant diversity. Seed banking is considered the most efficient and cost effective of these techniques but is applicable only to seed capable of tolerating desiccation and cold storage. Data on the degree of tolerance of these conditions was lacking for more than half of the 1503 South Pacific rainforest genera examined for this review.
