The Origin and Distribution of Phytophthora Cinnamomi
THE ORIGIN AND DISTRIBUTION OF PHYTOPHTHORA CINNAMOMI RANDS IN AUSTRALIAN NATIVE PLANT COMMUNITIES AND THE SIGNIFICANCE OF ITS ASSOCIATION WITH PARTICULAR PLANT SPECIES By B. H. PRATT* and W. A. HEATHER* [Manuscript received 23 October 1972] Abstract The origin, distribution, and disease association of P. cinnamomi in native plant communities in Australia has been examined. The fungus was isolated from the root zones of 31 plant genera in 16 families and is widespread throughout eastern and southern Australia and south-western Western Australia. Although the fungus is associated with disease in native plant communities it is also present in apparently non-diseased communities. Disease occurs usually only in environments disturbed by man, probably as a result of increase in population or activity of pre-existing fungal populations. The widespread distribution of P. cinnamomi in native vegetation in Australia, its occurrence in remote, undisturbed areas, and the apparent balance it has achieved with plant species of differing susceptibility to disease in some natural, undisturbed areas suggests that the fungus is likely to be indigenous to eastern Australia. Further, it may be partly responsible for the localized distribution of some plant species. I. INTRODUCTION The soil-borne fungus Phytophthora cinnamomi Rands is widely distributed in Australia, in horticultural plantings (Zentmyer and Thorn 1967; Pratt and Wrigley 1970; as well as personal communications from the New South Wales Department of Agriculture, Tasmanian Department of Agriculture, Victorian Department of Agriculture, and the Queensland Department of Primary Industries), and in conifer nurseries and plantings (Oxenham and Winks 1963; Bertus 1968; and personal communications from the New South Wales Forestry Commission, and the Queens land Department of Forestry). -

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). -

A Bibliography of Mycology and Plant Pathology in Ireland, 1976 to 2000
Glasra 4: 119 – 188 (2008) A bibliography of mycology and plant pathology in Ireland, 1976 to 2000 A. MANGAN 24 Treesdale, Blackrock, Co. Dublin ABSTRACT This bibliography includes medical and veterinary mycology, and plant pathology relating to bacteriology and virology. It is based on published work from Ireland, between 1976 and 2000 inclusive, and comprises 859 references. An index of topics is included. There is also a list of 193 theses for which Master or Doctorate degrees were awarded. INTRODUCTION In his publication, Mycology and Plant Pathology in Ireland, Muskett (1976) gave an account of the history and development of mycology and plant pathology in Ireland since the first traceable mention of Irish fungi in the scientific sense in 1726. His work included a bibliography containing 1,355 titles, in chronological order, covering the period from 1726 to 1975. The bibliography presented here covers the years 1976 to 2000. The basis of the present work was to search for work on mycology and plant pathology published by authors with an Irish address. Where work relating to Ireland, which was published from an address abroad, was noted, it is included but it was not possible to make a full search for such work. The principal sources for this work were: The Review of Plant Pathology and the Review of Medical and Veterinary Mycology, both published by CAB International. The following journals were also checked for relevant material: Irish Naturalists’ Journal Proceedings of the Royal Irish Academy Proceedings of meetings published by the Royal Irish Academy Scientific Proceedings of the Royal Dublin Society Journal of Life Sciences of the Royal Dublin Society Irish Journal of Agricultural Research later named the Irish Journal of Agricultural and Food Research Mycologist Field Mycology Various reports of meetings, institutes and societies exist, but are not included as they are not readily available in libraries. -

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. -

Inquiry Into the Problem of Feral and Domestic Cats in Australia to The
28 July 2020 Re: Inquiry into the problem of feral and domestic cats in Australia To the Committee Secretariat, Thank you for this opportunity to make a submission to the Inquiry into the problem of feral and domestic cats in Australia. The Society for Conservation Biology Oceania Section is the peak professional group for conservation biology in Australia, with 400 members that include conservation scientists, policy-makers and managers. Our role is to provide scientific information for management and policy decisions about the long term sustainability and future of ecosystems and their dependent organisms, recognising the importance of ecosystem services for humanity and based on the best available science. Feral and domestic cats have had severe impacts on Australian wildlife since their introduction by Europeans and will continue to do so into the foreseeable future. Feral cats threaten a large number of mammal, bird and reptile species and reducing the impacts of cats is critical to the conservation of Australia’s biodiversity. Reducing the impacts of cats is challenging and while there have been many advances in this space over the past 40 or so years, an effective, broadscale control tool remains elusive. As described in this submission, effectively reducing the impacts of cats on vulnerable fauna populations requires approaches that are tailored to the specifics of each management context, consider both lethal and non-lethal approaches, and take a whole-of-ecosystem approach, including accounting for other threats such as fire and grazing, and interactions with foxes, dingoes, rabbits and other species. We address terms of reference a, b, e, f and h in detail below. -
Rainfall and Temperatures Changes Have Confounding Impacts on Phytophthora Cinnamomi Occurrence Risk in the Southwestern USA Under Climate Change Scenarios
Global Change Biology Global Change Biology (2014), doi: 10.1111/gcb.12463 Rainfall and temperatures changes have confounding impacts on Phytophthora cinnamomi occurrence risk in the southwestern USA under climate change scenarios SALLY E. THOMPSON1 ,SIMONLEVIN2 andIGNACIO RODRIGUEZ-ITURBE3 1Department of Civil and Environmental Engineering, University of California, Berkeley, CA 94710, USA, 2Department of Ecology and Evolutionary Biology, Princeton University, Princeton NJ 08544, USA, 3Department of Civil and Environmental Engineering, Princeton University, Princeton, NJ 08544, USA Abstract Global change will simultaneously impact many aspects of climate, with the potential to exacerbate the risks posed by plant pathogens to agriculture and the natural environment; yet, most studies that explore climate impacts on plant pathogen ranges consider individual climatic factors separately. In this study, we adopt a stochastic modeling approach to address multiple pathways by which climate can constrain the range of the generalist plant pathogen Phy- tophthora cinnamomi (Pc): through changing winter soil temperatures affecting pathogen survival; spring soil tempera- tures and thus pathogen metabolic rates; and changing spring soil moisture conditions and thus pathogen growth rates through host root systems. We apply this model to the southwestern USA for contemporary and plausible future cli- mate scenarios and evaluate the changes in the potential range of Pc. The results indicate that the plausible range of this pathogen in the southwestern USA extends over approximately 200 000 km2 under contemporary conditions. While warming temperatures as projected by the IPCC A2 and B1 emissions scenarios greatly expand the range over which the pathogen can survive winter, projected reductions in spring rainfall reduce its feasible habitat, leading to spatially complex patterns of changing risk. -
