In supporting these core functions, we delivered best practice science to inform conservation and management of our plants, animals and ecosystems, and to support effective management of our parks and reserves, delivery of our fire program and managed use of our natural resources, as well as generating science stories that inspire and engage people with our natural heritage. Our activities are aligned with management priorities and we deliver science expertise in our core areas of conserving threatened plants, animals and communities, landscape scale conservation, wildlife assets and inventory, WA Herbarium, bushfire research, marine monitoring and research, forest monitoring and research, wetland monitoring, hydrological monitoring, and biodiversity data management and distribution.Some highlights of activities this year have been lack of detection of cats on Dirk Hartog Island, translocation of rock wallabies to Kalbarri National Park and dibblers to Gunton Island, establishment of a flatback turtle monitoring program on Thevenard Island and aerial surveys of turtle nesting on beaches in the Pilbara, surveys for bilbies and rare plants in the La Grange development area of the Kimberley, vertebrate survey in the northern part of the Matuwa Kurrara Kurrara Indigenous Protected Area with traditional owners, determining meteorological drivers of extreme fire behaviour during the Waroona bushfire, and monitoring on FORESTCHECK sites burnt in the Lower Hotham bushfire. In addition, the excellence of our science and its application in management was recognised by Western Shield winning the Premier’s Award for Excellence in Public Sector Management in the managing the environment category. I am very pleased that we continue to be key partners in the Western Australian Marine Science Institution and the Western Australian Biodiversity Science Institute. Although these joint ventures are at different stages in their funding cycles, we continue to make significant contributions to their programs, and gain substantial benefit from our engagement in these initiatives. I am also very pleased to have continued engagement with the National Environmental Science Program (NESP) hubs, as our staff provide a key perspective on the application of excellent science to address conserva- tion and management needs. In particular, programs of the Threatened Species Recovery hub and the Northern Australia Environmental Resources hub are strongly aligned with those of our department in delivering applied science and research outcomes to support on-ground management. Engagement with all our partners, both within the Department and externally, is an important component of how we deliver best practice science, and we continue to maintain excellent partnerships with universities, CSIRO, industry, not-for-profit organisations and other government agencies with many new projects and a large number of students that we co-supervise. We continue to build our relationship and engagement with traditional owners through research activities in the Pilbara, Western Desert and Kimberley This report will be our last report as the Department of Parks and Wildlife. From 1 July 2017 Parks and Wildlife was amalgamated with Botanic Gardens and Parks Authority, Zoological Parks Authority and Rottnest Island Authority to become the Department of Biodiversity, Conservation and Attractions. A key function of the new department is to consolidate conservation science into one department to build and share knowledge of WA’s biodiversity. I am confident we will continue to deliver excellence in applied science to support the core functions of the new department as we embrace the challenges and take advantage of the new opportunities provided by the amalgamation of these agencies.

    CHARACTERISATION OF EXPERIMENTALLY INDUCED AND SPONTANEOUSLY OCCURRING DISEASE WITHIN CAPTIVE BRED DASYURIDS Scott Andrew Lindsay A thesis submitted in fulfillment of requirements for the postgraduate degree of Masters of Veterinary Science Faculty of Veterinary Science University of Sydney March 2014 STATEMENT OF ORIGINALITY Apart from assistance acknowledged, this thesis represents the unaided work of the author. The text of this thesis contains no material previously published or written unless due reference to this material is made. This work has neither been presented nor is currently being presented for any other degree. Scott Lindsay 30 March 2014. i SUMMARY Neosporosis is a disease of worldwide distribution resulting from infection by the obligate intracellular apicomplexan protozoan parasite Neospora caninum, which is a major cause of infectious bovine abortion and a significant economic burden to the cattle industry. Definitive hosts are canid and an extensive range of identified susceptible intermediate hosts now includes native Australian species. Pilot experiments demonstrated the high disease susceptibility and the unexpected observation of rapid and prolific cyst formation in the fat-tailed dunnart (Sminthopsis crassicaudata) following inoculation with N. caninum. These findings contrast those in the immunocompetent rodent models and have enormous implications for the role of the dunnart as an animal model to study the molecular host-parasite interactions contributing to cyst formation. An immunohistochemical investigation of the dunnart host cellular response to inoculation with N. caninum was undertaken to determine if a detectable alteration contributes to cyst formation, compared with the eutherian models. Selective cell labelling was observed using novel antibodies developed against Tasmanian devil proteins (CD4, CD8, IgG and IgM) as well as appropriate labelling with additional antibodies targeting T cells (CD3), B cells (CD79b, PAX5), granulocytes, and the monocyte-macrophage family (MAC387).

  • Comparative Floral Presentation and Bee-Pollination in Two Sprengelia Species (Ericaceae)
    Comparative floral presentation and bee-pollination in two Sprengelia species (Ericaceae) Karen A. Johnson* and Peter B. McQuillan School of Geography and Environmental Studies, University of Tasmania, Private Bag 78, Hobart, Tasmania 7001, Australia. *Corresponding author. E-mail: [email protected] Abstract: Pollination by sonication is unusual in the Styphelioideae, family Ericaceae. Sprengelia incarnata and Sprengelia propinqua have floral characteristics that suggested they might be adapted to buzz pollination.Both species have florally similar nectarless flowers except that the stamens ofSprengelia propinqua spread widely after the flower opens, while those of Sprengelia incarnata cohere in the centre of the flower. To test whether sonication occurs, we observed bee behaviour at the flowers of both plant species, documented potential pollinators, and examined their floral and pollen attributes. We found that Sprengelia incarnata had smaller and drier pollen than Sprengelia propinqua. We found that Sprengelia incarnata was sonicated by native bees in the families Apidae (Exoneura), Halictidae (Lasioglossum) and Colletidae (Leioproctus, Euryglossa). Sprengelia propinqua was also visited by bees from the Apidae (Exoneura) and Halictidae (Lasioglossum), but pollen was collected by scraping. The introduced Apis mellifera (Apidae) foraged at Sprengelia propinqua but ignored Sprengelia incarnata. The two Sprengelia species shared some genera of potential pollinators, but appeared to have diverged enough in their floral and pollen characters to elicit different behaviours from the native and introduced bees.

  • Pollination Ecology and Evolution of Epacrids
    Pollination Ecology and Evolution of Epacrids by Karen A. Johnson BSc (Hons) Submitted in fulfilment of the requirements for the Degree of Doctor of Philosophy University of Tasmania February 2012 ii Declaration of originality This thesis contains no material which has been accepted for the award of any other degree or diploma by the University or any other institution, except by way of background information and duly acknowledged in the thesis, and to the best of my knowledge and belief no material previously published or written by another person except where due acknowledgement is made in the text of the thesis, nor does the thesis contain any material that infringes copyright. Karen A. Johnson Statement of authority of access This thesis may be made available for copying. Copying of any part of this thesis is prohibited for two years from the date this statement was signed; after that time limited copying is permitted in accordance with the Copyright Act 1968. Karen A. Johnson iii iv Abstract Relationships between plants and their pollinators are thought to have played a major role in the morphological diversification of angiosperms. The epacrids (subfamily Styphelioideae) comprise more than 550 species of woody plants ranging from small prostrate shrubs to temperate rainforest emergents. Their range extends from SE Asia through Oceania to Tierra del Fuego with their highest diversity in Australia. The overall aim of the thesis is to determine the relationships between epacrid floral features and potential pollinators, and assess the evolutionary status of any pollination syndromes. The main hypotheses were that flower characteristics relate to pollinators in predictable ways; and that there is convergent evolution in the development of pollination syndromes.

  • Fact Sheet: Eighty Mile Beach
    Fact Sheet: Eighty Mile Beach Region North Coast Summary Imagine an isolated beach of endless white sand, seashells and turquoise waters, stretching so far it would take more than a week to walk its length. Aptly named, Eighty Mile Beach is indeed long, stretching 220 kilometres and renowned as Australia's longest uninterrupted beach. With its midpoint halfway between Broome and Port Hedland, Eighty Mile Beach is like no other beach in Australia – where the desert (Great Sandy Desert) meets the sea (Indian Ocean). It differentiates itself from other beaches with its low windswept dunes, an almost continuous curving coastline, and large tidal ranges that expose some 60,000 hectares of sand and mudflats, widening the intertidal zone at low tide to almost four kilometres in some sections. Generated on 27/09/2021 https://marinewaters.fish.wa.gov.au/resource/fact-sheet-eighty-mile-beach/ Page 1 of 7 Figure 1. The wide expanse of the intertidal zone as the tide returns on Eighty mile beach (Image: Tahryn Thompson) The seascape is even more remarkable due to an extraordinary diversity of marine life, which includes up to 400,000 migratory shorebirds, rich benthic (mud) fauna, breeding turtles and the world’s largest stocks of wild pearl shell. The shorebirds and marine life of this wetland are recognised internationally under the Ramsar Convention. Eighty Mile Beach is sea country for the Karajarri people to the north, the Nyangumarta people over most of its length and the Ngarla people in the vicinity of Cape Keraudren. Mythological and ceremonial sites, Aboriginal art, shell middens and fish traps are found throughout the area and each group retains social, spiritual and cultural bonds with their traditional land and sea country.

  • Patterns in Ericaceae: New Phylogenetic Analyses
    BS 55 479 Origins and biogeographic patterns in Ericaceae: New insights from recent phylogenetic analyses Kathleen A. Kron and James L. Luteyn Kron, KA. & Luteyn, J.L. 2005. Origins and biogeographic patterns in Ericaceae: New insights from recent phylogenetic analyses. Biol. Skr. 55: 479-500. ISSN 0366-3612. ISBN 87-7304-304-4. Ericaceae are a diverse group of woody plants that span the temperate and tropical regions of the world. Previous workers have suggested that Ericaceae originated in Gondwana, but recent phy­ logenetic studies do not support this idea. The theory of a Gondwanan origin for the group was based on the concentration of species richness in the Andes, southern Africa, and the southwest Pacific islands (most of which are thought to be of Gondwanan origin). The Andean diversity is comprised primarily of Vaccinieae with more than 800 species occurring in northern South America, Central America, and the Antilles. In the Cape Region of South Africa the genus Erica is highly diverse with over 600 species currently recognized. In the southwest Pacific islands, Vac­ cinieae and Rhodoreae are very diverse with over 290 species of Rhododendron (sect. Vireya) and approximately 500 species of Vaccinieae (I)imorphanthera, Paphia, Vaccinium). Recent phyloge­ netic studies have also shown that the Styphelioideae (formerly Epacridaceae) are included within Ericaceae, thus adding a fourth extremely diverse group (approximately 520 species) in areas considered Gondwanan in origin. Phylogenetic studies of the family on a global scale, how­ ever, have indicated that these highly diverse “Gondwanan” groups are actually derived from within Ericaceae. Both Fitch parsimony character optimization (using MacClade 4.0) and disper- sal-vicariance analysis (DIVA) indicate that Ericaceae is Laurasian in origin.
