  • Husbandry Manual for the Shingleback Lizard Tiliqua Rugosa
    Husbandry Manual for The Shingleback Lizard Tiliqua rugosa GRAY, 1825 Reptilia:Scincidae Compiler: Andrew Titmuss Date of Preparation: 2007 University of Western Sydney, Hawkesbury © Andrew Titmuss 2007 1 A Husbandry Manual template has been developed to standardise information on captive management needs in a concise, accessible and usable form. Currently there is no Husbandry Manual for the Shingleback Lizard. As these lizards are commonly kept in zoological and private collections in Australia and internationally, a Husbandry Manual could be widely used. This Husbandry Manual is set out as per the husbandry manual template designed by Stephen Jackson and Graeme Phipps. The template is a document that was created to maintain husbandry manual uniformity and thus its effectiveness and ease of use. It is intended as a working document. It is designed to be used by any institution, as well as private collections, holding this species. Although these lizards are easy to keep in captivity they do have some special requirements. The aim of the Husbandry Manual is to summarise and consolidate information regarding OHS, natural history, captive management and ethical husbandry techniques and conservation from a variety of sources. It should provide information on appropriate husbandry with scope for improved health and welfare and captive breeding if required. The University of Western Sydney, Hawkesbury Campus, is planning on keeping Shingleback Lizards amongst other species in their reptile unit. This manual can be used by the University of

  • Wildlife Parasitology in Australia: Past, Present and Future
    CSIRO PUBLISHING Australian Journal of Zoology, 2018, 66, 286–305 Review https://doi.org/10.1071/ZO19017 Wildlife parasitology in Australia: past, present and future David M. Spratt A,C and Ian Beveridge B AAustralian National Wildlife Collection, National Research Collections Australia, CSIRO, GPO Box 1700, Canberra, ACT 2601, Australia. BVeterinary Clinical Centre, Faculty of Veterinary and Agricultural Sciences, University of Melbourne, Werribee, Vic. 3030, Australia. CCorresponding author. Email: [email protected] Abstract. Wildlife parasitology is a highly diverse area of research encompassing many fields including taxonomy, ecology, pathology and epidemiology, and with participants from extremely disparate scientific fields. In addition, the organisms studied are highly dissimilar, ranging from platyhelminths, nematodes and acanthocephalans to insects, arachnids, crustaceans and protists. This review of the parasites of wildlife in Australia highlights the advances made to date, focussing on the work, interests and major findings of researchers over the years and identifies current significant gaps that exist in our understanding. The review is divided into three sections covering protist, helminth and arthropod parasites. The challenge to document the diversity of parasites in Australia continues at a traditional level but the advent of molecular methods has heightened the significance of this issue. Modern methods are providing an avenue for major advances in documenting and restructuring the phylogeny of protistan parasites in particular, while facilitating the recognition of species complexes in helminth taxa previously defined by traditional morphological methods. The life cycles, ecology and general biology of most parasites of wildlife in Australia are extremely poorly understood. While the phylogenetic origins of the Australian vertebrate fauna are complex, so too are the likely origins of their parasites, which do not necessarily mirror those of their hosts.

  • Investigations Into the Presence of Nidoviruses in Pythons Silvia Blahak1, Maria Jenckel2,3, Dirk Höper2, Martin Beer2, Bernd Hoffmann2 and Kore Schlottau2*
    Blahak et al. Virology Journal (2020) 17:6 https://doi.org/10.1186/s12985-020-1279-5 RESEARCH Open Access Investigations into the presence of nidoviruses in pythons Silvia Blahak1, Maria Jenckel2,3, Dirk Höper2, Martin Beer2, Bernd Hoffmann2 and Kore Schlottau2* Abstract Background: Pneumonia and stomatitis represent severe and often fatal diseases in different captive snakes. Apart from bacterial infections, paramyxo-, adeno-, reo- and arenaviruses cause these diseases. In 2014, new viruses emerged as the cause of pneumonia in pythons. In a few publications, nidoviruses have been reported in association with pneumonia in ball pythons and a tiger python. The viruses were found using new sequencing methods from the organ tissue of dead animals. Methods: Severe pneumonia and stomatitis resulted in a high mortality rate in a captive breeding collection of green tree pythons. Unbiased deep sequencing lead to the detection of nidoviral sequences. A developed RT-qPCR was used to confirm the metagenome results and to determine the importance of this virus. A total of 1554 different boid snakes, including animals suffering from respiratory diseases as well as healthy controls, were screened for nidoviruses. Furthermore, in addition to two full-length sequences, partial sequences were generated from different snake species. Results: The assembled full-length snake nidovirus genomes share only an overall genome sequence identity of less than 66.9% to other published snake nidoviruses and new partial sequences vary between 99.89 and 79.4%. Highest viral loads were detected in lung samples. The snake nidovirus was not only present in diseased animals, but also in snakes showing no typical clinical signs.

  • Blueys in the Bush: Short Notes on the Distribution and Habitat Of
    Blueys in the bush: Short notes on the distribution and habitat of Tiliqua and Cyclodomorphus in New South Wales, Australia. Steven Sass1,2 1nghenvironmental, PO Box 470, Bega NSW. e [email protected] 2Ecology and Biodiversity Group, Institute for Land, Water and Society, Charles Sturt University, Thurgoona NSW. The ‘blue tongue’ lizards are regarded as one of the most iconic reptile species in Australia (Koenig et al., 2001). The Tiliqua are a familiar genus whose members are often encountered in suburbia and along country roads, while the Cyclodomorphus are shy and secretive and rarely observed. ‘Blue tongues’ can be found in almost every part of the continent, with the state of New South Wales being no exception. This paper provides some short notes on the distribution and habitat of Tiliqua and Cyclodomorphus that are known to occur within New South Wales. Tiliqua Of the six species of Tiliqua that occur in Australia, five of these are known to occur in NSW. The Pygmy Blue-tongue Tiliqua adelaidensis occurs in South Australia (Armstrong and Reid, 1992). A sub-species of the Eastern Blue-tongue, the Northern Blue-tongue Tiliqua scincoides intermedia, is found across northern Queensland, Northern Territory and Western Australia (Wilson and Swan, 2008). Tiliqua multifasciata The Centralian Blue tongue is known only to occur in NSW within Sturt National Park (Swan et al., 2004; DECC, 2008a) (Figure 1). The species has been recorded within spinifex grasslands in sandy areas (Swan et al., 2004) (Plate 1). In other parts of its range outside of NSW, the species has also been found where spinifex occurs on stony ground (Fyfe, 1983; Wilson and Swan, 2008).

  • I Exploring the Relationship Between Paleobiogeography, Deep-Diving
    Exploring the Relationship between Paleobiogeography, Deep-Diving Behavior, and Size Variation of the Parietal Eye in Mosasaurs By Andrew M. Connolly Submitted to the graduate degree program in Geology and the Graduate Faculty of the University of Kansas in partial fulfillment of the requirements for the degree of Master of Arts. __________________________________ Stephen T. Hasiotis, Chairperson __________________________________ Rafe M. Brown __________________________________ Jennifer A. Roberts Date Defended: March 25, 2016 i The Thesis Committee for Andrew M. Connolly certifies that this is the approved version of the following thesis: Exploring the Relationship between Paleobiogeography, Deep-Diving Behavior, and Size Variation of the Parietal Eye in Mosasaurs __________________________________ Stephen T. Hasiotis, Chairperson Date Approved: March 25, 2016 ii ABSTRACT Andrew M. Connolly, M.S. Department of Geology, March 2015 University of Kansas The parietal eye (PE) in modern squamates (Reptilia) plays a major role in regulating body temperature, maintaining circadian rhythms, and orientation via the solar axis. This study is the first to determine the role, if any, of the PE in an extinct group of lizards. We analyzed variation in relative size of the parietal foramen (PF) of five mosasaur genera to explore the relationship between PF size and paleolatitudinal distribution. We also surveyed the same specimens for the presence of avascular necrosis—a result of deep- diving behavior—in the vertebrae. Plioplatecarpus had the largest PF followed by Platecarpus, Tylosaurus, Mosasaurus, and Clidastes. A weak relationship exists between paleolatitudinal distribution and PF size among genera, as Plioplatecarpus had the highest paleolatitudinal distribution (~78°N) and the largest PF among genera.

  • Fauna of Australia 2A
    FAUNA of AUSTRALIA 13. HISTORY OF DISCOVERY OF THE REPTILIA Harold G. Cogger 13. HISTORY OF DISCOVERY OF THE REPTILIA FIRST ENCOUNTERS When Australia was first encountered by Asian and European seafarers, the entire continent, together with Tasmania, was occupied by indigenous peoples who had an intimate knowledge of the country’s reptiles and their habits. Reptiles then and now figure large in Aboriginal culture, including art and religion. It is ironic that herpetologists (Cogger 1970) first formally recorded the pig-nosed turtle (Carettochelys insculpta) from Australia in 1970, only to find later that this species had long ago been recorded for posterity by Aboriginal artists in the caves of western Arnhem Land (Fig. 13.1). The large Oenpelli python, Morelia oenpelliensis, was not known to science until 1975 (Gow 1977), but is also recorded in the early rock art of Arnhem Land. Before the discovery of the eastern coast of Australia by Captain James Cook in 1770, and the subsequent establishment of the first European settlement in Australia—the British penal settlement at Sydney (Port Jackson) in 1788— Australia had been visited, though not always intentionally, by a number of European seafarers and explorers (Whitley 1970). Few records (and apparently no specimens) derived from these early encounters with the Australian fauna exist. Whitley (1970) recorded that no reptiles were among the few Australian animals recorded, apart from crocodiles and marine turtles noted from the southern coastal waters of New Guinea by the Spaniard Luis Vaez de Torres, who in 1606 passed through the Strait subsequently named in his honour.
