    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).

  • Synoptic-Scale Control Over Modern Rainfall and Flood Patterns in the Levant Drylands with Implications for Past Climates
    JUNE 2018 ARMONETAL. 1077 Synoptic-Scale Control over Modern Rainfall and Flood Patterns in the Levant Drylands with Implications for Past Climates MOSHE ARMON Fredy and Nadine Herrmann Institute of Earth Sciences, Hebrew University of Jerusalem, Givat Ram, Jerusalem, Israel ELAD DENTE Fredy and Nadine Herrmann Institute of Earth Sciences, Hebrew University of Jerusalem, Givat Ram, and Geological Survey of Israel, Jerusalem, Israel JAMES A. SMITH Department of Civil and Environmental Engineering, Princeton University, Princeton, New Jersey YEHOUDA ENZEL AND EFRAT MORIN Fredy and Nadine Herrmann Institute of Earth Sciences, Hebrew University of Jerusalem, Givat Ram, Jerusalem, Israel (Manuscript received 23 January 2018, in final form 1 May 2018) ABSTRACT Rainfall in the Levant drylands is scarce but can potentially generate high-magnitude flash floods. Rainstorms are caused by distinct synoptic-scale circulation patterns: Mediterranean cyclone (MC), active Red Sea trough (ARST), and subtropical jet stream (STJ) disturbances, also termed tropical plumes (TPs). The unique spatiotemporal char- acteristics of rainstorms and floods for each circulation pattern were identified. Meteorological reanalyses, quantitative precipitation estimates from weather radars, hydrological data, and indicators of geomorphic changes from remote sensing imagery were used to characterize the chain of hydrometeorological processes leading to distinct flood patterns in the region. Significant differences in the hydrometeorology of these three flood-producing synoptic systems were identified: MC storms draw moisture from the Mediterranean and generate moderate rainfall in the northern part of the region. ARST and TP storms transfer large amounts of moisture from the south, which is converted to rainfall in the hyperarid southernmost parts of the Levant.

Maloney2 1School of Animal Biology, Faculty of Natural and Agricultural Sciences and 2School of Anatomy, Physiology and Human Biology, Faculty of Life and Physical Sciences, The University of Western Australia, Crawley 6009 WA, Australia *Author for correspondence ([email protected]) SUMMARY Stripe-faced dunnarts (Sminthopsis macroura) and Ooldea dunnarts (S. ooldea) were acclimated for 2weeks to ambient temperature (Ta) regimes of 12–22°C, 18–28°C and 25–35°C, and then measured for standard, basal (BMR) and maximum (MMR) metabolic rate using flow-through respirometry. Sminthopsis macroura maintained a stable body temperature under all experimental Ta and acclimation regimes. Although its BMR was not statistically different between the three acclimation regimes, the lower end of the thermoneutral zone (TNZ) shifted from 30°C under the 18–28°C and 12–22°C acclimation regimes to 35°C under the 25–35°C acclimation regime. MMR increased significantly at the cooler acclimation regimes. EWL increased at Ta35°C, compared with lower Ta, in all acclimation regimes, but an increase in evaporative water loss (EWL) at Ta10°C observed in cool acclimations did not occur at the 25–35°C regime. In contrast, S. ooldea had variable body temperature between experimental Ta in all acclimation regimes, but no acclimational shift in TNZ, which was between 30 and 35°C.

  • THE MAKING of the NEWCASTLE INDUSTRIAL HUB 1915 to 1950
    THE MAKING OF THE NEWCASTLE INDUSTRIAL HUB 1915 to 1950 Robert Martin Kear M.Bus. (University of Southern Queensland) A thesis submitted in fulfilment of the requirements for the degree of a Master of Philosophy in History January 2018 This research was supported by an Australian Government Research Training Program (RTP) Scholarship STATEMENT OF ORIGINALITY I hereby certify that the work embodied in the thesis is my own work, conducted under normal supervision. The thesis contains no material which has been accepted, or is being examined, for the award of any other degree or diploma in any other university or other tertiary institution and, to the best of my knowledge and belief, contains no material previously published or written by another person, except where due reference has been made in the text. I give consent to the final version of my thesis being made available worldwide when deposited in the University’s Digital Repository, subject to the provisions of the Copyright Act 1968 and any approved embargo. Robert Kear ii ABSTRACT Aim of this Thesis The aim of this thesis is to chart the formation of the Newcastle Industrial Hub and to identify the men who controlled it, in its journey from Australian regional obscurity before 1915, to be the core of Australian steel manufacturing and technological development by 1950. This will be achieved through an examination of the progressive and consistent application of strategic direction and the adoption of manufacturing technologies that progressively lowered the manufacturing cost of steel. This thesis will also argue that, coupled with tariff and purchasing preferences assistance, received from all levels of government, the provision of integrated logistic support services from Newcastle’s public utilities and education services underpinned its successful commercial development.

  • Ba3444 MAMMAL BOOKLET FINAL.Indd
    Intot Obliv i The disappearing native mammals of northern Australia Compiled by James Fitzsimons Sarah Legge Barry Traill John Woinarski Into Oblivion? The disappearing native mammals of northern Australia 1 SUMMARY Since European settlement, the deepest loss of Australian biodiversity has been the spate of extinctions of endemic mammals. Historically, these losses occurred mostly in inland and in temperate parts of the country, and largely between 1890 and 1950. A new wave of extinctions is now threatening Australian mammals, this time in northern Australia. Many mammal species are in sharp decline across the north, even in extensive natural areas managed primarily for conservation. The main evidence of this decline comes consistently from two contrasting sources: robust scientifi c monitoring programs and more broad-scale Indigenous knowledge. The main drivers of the mammal decline in northern Australia include inappropriate fi re regimes (too much fi re) and predation by feral cats. Cane Toads are also implicated, particularly to the recent catastrophic decline of the Northern Quoll. Furthermore, some impacts are due to vegetation changes associated with the pastoral industry. Disease could also be a factor, but to date there is little evidence for or against it. Based on current trends, many native mammals will become extinct in northern Australia in the next 10-20 years, and even the largest and most iconic national parks in northern Australia will lose native mammal species. This problem needs to be solved. The fi rst step towards a solution is to recognise the problem, and this publication seeks to alert the Australian community and decision makers to this urgent issue.

  • Regolith-Landforms and Plant Biogeochemical Expression of Buried Mineralisation Targets in the Northern Middleback Ranges, (“Iron Knob South”) South Australia
    Regolith-Landforms and plant biogeochemical expression of buried mineralisation targets in the Northern Middleback Ranges, (“Iron Knob South”) South Australia Louise Thomas Geology and Geophysics, School of Earth and Environmental Science, University of Adelaide, Adelaide SA 5005, Australia A manuscript submitted for the Honours Degree of Bachelor of Science, University of Adelaide, 2011 Supervised by Dr. Steven M. Hill 2 ABSTRACT South of the town Iron Knob on the northern Eyre Peninsula, a tenement scale plant biogeochemical survey and regolith-landform mapping, combined to define areas with elevated Cu, Zn and Au contents that are worthy of follow-up exploration. Plant biogeochemistry was conducted within a 6 Km2 area with 1 Km spacing between each E-W trending transect and 200 m spacing between each sample. A regolith-landform map presents the distribution of regolith materials and associated landscape processes to help constrain geochemical dispersion. A Philips XL30 SEM provided insight into how the plants uptake certain elements and distribute them within the organs structure. Two zones of elevated trace metals (e.g. Cu, Au and Zn) were defined either side of a NW-SE structure crossing over the N-S trending „Katunga‟ ridge. Both targets were located on similar regolith-landform units of sheet-flood fans and alluvial plains. Copper and Zn results were best represented by the western myall species while the bluebush species was best at detecting Au. A follow up study targeting the NW-SE structure with closer sample spacing is recommended in further constraining drilling targets. For the tenement holding company, Onesteel Ltd, these results are significant as they define two new areas of interest for possible IOCG mineralisation.

  • Sect. Phyllodineae), a New Species from Eyre Peninsula, South Australia M.C
    J. Adelaide Bot. Gard. 20: 17-20 (2002) ACACIA TOONDULYA (LEGUMINOSAE: MIMOSOIDEAE: SECT. PHYLLODINEAE), A NEW SPECIES FROM EYRE PENINSULA, SOUTH AUSTRALIA M.C. O'Leary State Herbarium of South Australia, Plant Biodiversity Centre PO Box 2732, Kent Town, South Australia 5071 Email: [email protected] Abstract A new species, Acacia toondulya, is described and illustrated. It has a restricted distribution in the western Gawler Ranges, Eyre Peninsula, South Australia and is most closely related to A. notabilis. Introduction The taxon described here as A. toondulya was first collected in 1969, and again in 1972. These specimens were identified as A. beckleri and A. notabilis due to their large phyllodes and flowers, or pods with transverse seed. A specimen collected from Toondulya Bluff in 1981 with a distinct pruinose coating on its branchlets and racemes (but in young bud) at first remained undetermined for some time and then finally identified as A. cretacea. At this time a study of the biology of A. cretacea was being conducted by the Conservation Biology Unit at the Black Hill Flora Park, and with earlier reports of populations of A. cretacea occurring in the Gawler Ranges a visit was made to Toondulya Bluff. The resulting collections made with inflorescences containing 80 flowers per head, pods with transverse seed, and photos showing a slender, erect habit, indicated all the previous determinations to be incorrect. This relatively inaccessible and poorly collected area was then visited by the author, where population collections and field studies have shown this taxon to be worthy of formal species ranking.
