2007–081.21 Mb DIRECTOR'S MESSAGE The theme of my foreword this year is "connectivity". Just as maintaining the opportunity for connectedness is important for the conservation of biodiversity, it remains crucial for the relevance and application of scientific research in the Department of Environment and Conservation (DEC). This year has been particularly pleasing, as the Science Division and DEC are beginning to see the benefits from recent years of heightened activity in investing time and effort in both internal and external consultation, co-operation, co-ordination and collaboration. In 2007/08, the Division was involved in around 150 research-related projects in DEC, over 100 projects with external partners and 77 projects with tertiary students. Working with DEC Divisions Within DEC, close working relationships were maintained across a number of DEC Divisions. Examples include: • Working closely with field officers in the Division of Regional Services on active adaptive management projects such as the Walpole Fire Mosaic Project, the Woylie Conservation Project (Warren Region) and the Operation Rangelands Restoration project at Lorna Glen (Goldfields Region). • The Regional “science ambassador” program is working well with science ambassadors providing a conduit for information flow between Science Division and Regional Services Division. Science Ambassadors have attended and given presentations at the annual regional meetings for Midwest, Wheatbelt and South Coast Regions. These presentations have highlighted collaborative studies such as research associated with the design and assessment of success for flora translocations in the South Coast, Wheatbelt and Midwest Regions. The Division has also provided technical advice to important initiatives, such as the Gnangara Sustainability Strategy. • Working closely with Nature Conservation Division and Sustainable Forest Management Division in provision of advice and in conservation planning. Examples include participation in the development of DEC’s nine Nature Conservation Service Region Plans; State of the Forests Report 2008 to which Science Division staff contributed significantly; establishment of a network of Fire Exclusion Reference Areas (FERA) in south-west forests in collaboration with Fire Management Services Branch; technical advice and review to the three Resource Condition Monitoring (Significant Native Species and Ecological Communities, Vegetation Condition, Wetland Condition) projects; assisting Area Management Planners with provision of accurate and relevant information relating to the Walpole Wilderness Area and adjacent parks and reserves; draft management plans for Leeuwin Ridge, Scott National Park and Gingilup Swamp Nature Reserve. • Working closely with Environmental Management Branch, Environmental Protection Authority Services Unit and Environmental Analysis and Review Branch in the provision of advice on biodiversity surveys and conservation issues associated with resource development throughout the State. Key interactions include the strategic review of banded iron formation (BIF) ranges of the Midwest and Goldfields; input into the quarantine and hazard procedures for the Gorgon development on Barrow Island; input into the Northern Taskforce review of development hubs in the Kimberly; development of draft guidelines for biological survey and input into numerous Environmental Impact Assessment and Vegetation Clearing submissions. Linking more effectively with universities In addition to formal meetings between Divisional senior scientists and academic staff to share information and to identify areas of potential collaboration in the future, DEC Science Division continues to collaborate through ARC Linkage Grants, student scholarships and co-supervision of students (see summaries on page 232 of this report). In addition, over the last 12 months, three joint appointments have been made with Western Australian Universities, two with the School of Plant Biology, University of Western Australia and one with the School of Biological Sciences, Murdoch University. Investing in national and international collaborations This year has seen a continuation of partnerships with the Bushfire CRC; Future Farm Industries CRC; CSIRO Project Vesta; CSIRO Clean Air Research Programs; Australian Long Term Ecological Research site network, and the Western Australian Marine Science Institution. The Millennium Seed Bank-Western Australia partnership, now in its 8th year, has helped achieve a more secure future for many of the State's conservation-listed flora. Currently one half of all species held in storage at the Threatened Flora Seed Centre are duplicated at the Millennium Seed Bank, while the collections have provided the basis for more than 35 translocations. The importance of the Millennium Seed Bank and similar seed stores is increasing as the scale of potential climate change impacts on species and ecosystems becomes more evident. Our understanding of potential climate change impacts has become sounder as a result of greater Divisional focus on science relating to climate change biodiversity interactions, a growing collaboration on this matter with Western Australian scientists based at tertiary institutions and our collaboration with the Climate Change Science team at the South African National Biodiversity Institute. The great similarities and key differences between Western Australia's south west region and South Africa cape region have supported the development of comparative studies and assessments which are revealing greater knowledge about the potential vulnerabilites of both regions. Collaborating with the corporate sector The Division has continued to develop partnerships and sponsorship arrangements with industry and corporate institutions. Examples include the Understanding Mulga project – the largest externally funded taxonomic project undertaken in Australia; the Pilbara Wattle project; and the mutually beneficial ‘embedding’ of identification botanists in the WA Herbarium by BHP Billiton Iron Ore and Rio Tinto Iron Ore. Generating Science to support conservation I am also mindful of the converse of connectivity. In evolution most new species form as a result of allopatry or vicariance, essentially a form of temporary isolation from other populations. In science, the great leaps forward are likely to come from individual scientists and not from committees of scientists. These acts of creative insight arise from a hard-to-characterize connection between awareness and mastery of knowledge as it is published in the professional journals and intense individual thinking about the problems to be solved. Science Division continues to invest in maintaining a quality Departmental library of science journals, relevant grey literature including reports by ecological consultants to industry, and official documents. Library services are provided across DEC and external to the Department. A recent general usage survey found that these services are highly valued by staff across the Department. Within DEC, the Science Division usage of DEC library services is 53%, and the next highest users are Nature Conservation Division (16%), Regional Services Division (13%) and Parks and Visitor Services Division (10%). The Library Catalogue has 155 201 records: • 28 478 book/report titles • 1 671 journal/newsletter titles (564 current) 2 • 10 765 monographic journals • 26 528 reprints • 65 968 indexed journal articles and book chapters • 2 774 pamphlets • 762 links to online resources • 4 500 PDFs linked to catalogue records The Science Division publishes two journals, Conservaiton Science WA and Nuytsia. Three issues of Conservation Science WA were published this year with 770 pages including two special issues – a complete translation of Dr L Diels 1906 Plant Life of Western Australian, a seminal work on Western Australian biogeography; and Ian Abbott's historical perspectives on the ecology of south western Australian vertebrates. Three issues of Nuytsia were published with 706 pages of taxonomica support including a special issue on species of the Banded Ironstone Formation ranges of the Yilgarn Craton and the Ravensthorpe Range and Bandalup Hill to facilitate greater understanding of the biodiversity of these regions. Science Division operates nine Research Centres with associated administration support. We cannot function without the valuable role that our administration staff play. It is the long term intention of DEC to collocate the three science metropolitan centres to a new building at Kensington. This year saw site works commence for Stage 1 which includes the Western Australian Herbarium and most sections of the Flora Conservation and Herbarium Program, the Science Directorate and the Science Division library. The total cost is estimated at over $30 million. Science Division also operates molecular genetic laboratories and plant pathology laboratories, including the Vegetation Health Service which is the State's primary source of data for Phytophthora dieback identification. The Western Australian Herbarium houses the State's collections of vascular, non vascular (algae, mosses, etc.) plants and fungi totalling 683 339 specimens.

  • Ericaceae Root Associated Fungi Revealed by Culturing and Culture – Independent Molecular Methods
    a Ericaceae root associated fungi revealed by culturing and culture – independent molecular methods. by Damian S. Bougoure BSc (Hons) Thesis submitted in accordance with the requirements for the degree of Doctor of Philosophy Centre for Horticulture and Plant Sciences University of Western Sydney February 2006 2 ACKNOWLEDGEMENTS Although I am credited with writing this thesis there is a multitude of people that have contributed to its completion in ways other than hitting the letters on a keyboard and I would like to thank them here. Firstly I’d like to thank my supervisor, Professor John Cairney, whose knowledge and guidance was invaluable in steering me along the PhD path. The timing of John’s ‘motivational chats’ was uncanny and his patience particularly, during the writing stage, seemed limitless at times. I’d also like to thank the Australian government for granting me an Australian Postgraduate Award (APA) scholarship, Paul Worden from Macquarie University and the staff from the Millennium Institute at Westmead Hospital for performing DNA sequencing and the National Parks and Wildlife Service of New South Wales and Environmental Protection agency of Queensland for permission to collect the Ericaceae plants. Thankyou to Mary Gandini from James Cook University for showing me the path to a Rhododendron lochiae population through the thick North Queenland rainforest. Without her help and I’d still be pointing the GPS at the sky. Thankyou to the other people in the lab studying mycorrhizas including Catherine Hitchcock, Susan Chambers, Adrienne Williams and particularly Brigitte Bastias with whom I shared an office. Everyone mentioned was generally just as willing as I was to talk about matters other than mycorrhizas.

  • (Reptilia: Squamata: Scincidae) Species Group and a New Species of Immediate Conservation Concern in the Southwestern Australian Biodiversity Hotspot
    Zootaxa 3390: 1–18 (2012) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ Article ZOOTAXA Copyright © 2012 · Magnolia Press ISSN 1175-5334 (online edition) Molecular phylogeny and morphological revision of the Ctenotus labillardieri (Reptilia: Squamata: Scincidae) species group and a new species of immediate conservation concern in the southwestern Australian biodiversity hotspot GEOFFREY M. KAY & J. SCOTT KEOGH 1 Division of Evolution, Ecology and Genetics, Research School of Biology, The Australian National University, Canberra, ACT 0200, Australia 1 Corresponding author. E-mail: [email protected] Abstract Ctenotus is the largest and most diverse genus of skinks in Australia with at least 97 described species. We generated large mitochondrial and nuclear DNA data sets for 70 individuals representing all available species in the C. labillardieri species- group to produce the first comprehensive phylogeny for this clade. The widespread C. labillardieri was sampled extensively to provide the first detailed phylogeographic data set for a reptile in the southwestern Australian biodiversity hotspot. We supplemented our molecular data with a comprehensive morphological dataset for the entire group, and together these data are used to revise the group and describe a new species. The morphologically highly variable species C. labillardieri comprises seven well-supported genetic clades that each occupy distinct geographic regions. The phylogeographic patterns observed in this taxon are consistent with studies of frogs, plants and invertebrates, adding strength to emerging biogeographic hypotheses in this iconic region. The species C. catenifer, C. youngsoni, and C. gemmula are well supported, and despite limited sampling both C. catenifer and C. gemmula show substantial genetic structure.

Email: [email protected] ABSTRACT A total of 243 taxa, 233 native and 10 weeds, were recorded from study of the flora and plant communities of the Mount Gibson Range and surrounding ironstone ranges on the Ninghan pastoral lease, 60 km southeast of Paynes Find. Seven priority flora, one declared rare flora and one new species were identified during the study. Fifty quadrats were established to cover the geomorphology, floristic variation and geographical variation across the ranges. Data from these quadrats were used to define seven community types. Geography and landscape morphology separated the communities, with four communities found only on the Mount Gibson Range. Of these four, two had restricted distributions within the range. None of the ranges are currently reserved in the conservation estate. INTRODUCTION geology of the Mount Gibson area is complex and composed of several fold belts. The Retaliation Belt is Banded Iron Formation (BIF) ranges within the Yilgarn represented mainly by the Mount Gibson Range and is Craton are highly prospective for iron ore exploration and comprised of banded iron formations and cherts in the mining. Previous studies on ironstone and greenstone lower sedimentary association, bounded by volcanic flows ranges in the Goldfields have found high plant endemicity with marker bands of banded ironstone formation. The and restricted plant communities and it is thought that Yandhanoo Hills and small hills near Warro Well (Figure these patterns may also be found on the ranges in the 1) are part of the Yandhanoo Belt.

  • Flora and Vegetation: Markey and Dillon 2008
    Conservation Science W. Aust. 7 (1) : 121–149 (2008) Flora and vegetation of the banded iron formations of the Yilgarn Craton: the central Tallering Land System ADRIENNE S. MARKEY AND STEVEN J. DILLON Science Division, Department of Environment and Conservation, Wildlife Research Centre, PO Box 51, Wanneroo WA 6946 Email: [email protected] ABSTRACT A quadrat-based survey was undertaken on the flora and floristic communities of several ironstone ranges and outcrops in the Yalgoo bioregion, covering the central extent of the Tallering Land System. One hundred and three 20 x 20 m quadrats were established over the extent of this region, and covered the topographic profile of these landforms. A total of 414 taxa (species, subspecies, varieties and forms) and four hybrids were identified from these quadrats. Fifteen taxa of conservation significance were found in this survey, five of which had not been previously recorded from the area. Significant range extensions for 21 species are reported in this study. At least nine new taxa were identified, of which several are of conservation significance. Nine regional endemic and near-endemic taxa were found over the study area, with half restricted to the south-west hills. Eight floristic community types (five main types, two with subtypes) were resolved from classification analysis of floristic data (presence / absence). These community types were strongly associated with topography and soil chemistry. Geographical variation was found among the floristic communities within the region, and some communities were found to be restricted to the south-west of the survey area. These restricted communities were found to occur in the more mesic regions of the survey area, on rocky uplands of BIF, and had notable component of flora from the South West Floristic Region.
