Parasite Metacommunities: Evaluating The Roles Of Host Community Composition And Environmental Gradients In Structuring Symbiont Communities Within Amphibians, Joseph Mihaljevic, Bethany J. Hoye, Pieter Johnson

Faculty of Science, Medicine and Health - Papers: part A

Ecologists increasingly report the structures of metacommunities for free-living species, yet far less is known about the composition of symbiont communities through space and time. Understanding the drivers of symbiont community patterns has implications ranging from emerging infectious disease to managing host microbiomes. Using symbiont communities from amphibian hosts sampled from wetlands of California, USA, we quantified the effects of spatial structure, habitat filtering and host community components on symbiont occupancy and overall metacommunity structure. We built upon a statistical method to describe metacommunity structure that accounts for imperfect detection in survey data-detection error-corrected elements of metacommunity structure-by adding an …

Comparative Copper Sensitivity Between Life Stages Of Common Subantarctic Marine Invertebrates, Jessica Holan, Catherine K. King, Andrew R. Davis

Faculty of Science, Medicine and Health - Papers: part A

The development of environmental guidelines in the Antarctic and subantarctic is essential, because expansion of research, tourism, and fishing is placing these regions at increasing risk of contamination. Data are currently insufficient to create the region-specific guidelines needed for the unique conditions in these areas. To develop the most appropriate environmental guidelines, data from the most sensitive life stages of a species should be included to ensure effective protection throughout its life cycle. It is generally accepted that early life stages are more sensitive to contaminants. We compared the toxicity of copper between juvenile and adult life stages of 4 …

Western wildfires have a major impact on air quality in the US. In the fall of 2016, 107 test fires were burned in the large-scale combustion facility at the US Forest Service Missoula Fire Sciences Laboratory as part of the Fire Influence on Regional and Global Environments Experiment (FIREX). Canopy, litter, duff, dead wood, and other fuel components were burned in combinations that represented realistic fuel complexes for several important western US coniferous and chaparral ecosystems including ponderosa pine, Douglas fir, Engelmann spruce, lodgepole pine, subalpine fir, chamise, and manzanita. In addition, dung, Indonesian peat, and individual coniferous ecosystem fuel …

The Use Of Time-Averaged Concentrations Of Metals To Predict The Toxicity Of Pulsed Complex Effluent Exposures To A Freshwater Alga, Brad M. Angel, Kathryn Goodwyn, Dianne F. Jolley, Stuart L. Simpson

Faculty of Science, Medicine and Health - Papers: part A

Intermittent, fluctuating and pulsed contaminant discharges may result in organisms receiving highly variable toxicant exposures. This study investigated the toxicity of continuous and pulsed exposures of a complex, neutralised drainage water (NDW) and dissolved copper-spiked dilute NDW to the green alga, Pseudokirchneriella subcapitata. The effects of single pulses of between 1 and 48 h duration and continuous exposures (72 h) on algal growth rate inhibition were compared on a time-averaged concentration (TAC) basis. Algal growth rates generally recovered to control levels within 24e48 h of the pulse removal. Continuous exposures to NDW resulted in similar or marginally higher toxicity …

Students Use Of Exemplars To Support Academic Writing In Higher Education: An Integrative Review, Rebekah B. Carter, Yenna Salamonson, Lucie Ramjan, Elizabeth J. Halcomb

Faculty of Science, Medicine and Health - Papers: part A

Background: Timely and meaningful feedback is essential to promote active learning and student engagement with learning. However, achieving this remains elusive, particularly in undergraduate nursing programs that admit large student cohorts. One strategy to provide meaningful en masse feedback is to provide feed-forward support by using exemplars. To date, there has been limited evaluation of the effectiveness of this feedback strategy.

Objective: To review the impact of using exemplars as a feedback strategy to support student academic writing in higher education.

Data Sources and Review Method: A systematic search of electronic databases for original research papers published …

Devil Facial Tumour Disease (DFTD), a highly contagious cancer, has decimated Tasmanian devil (Sarcophilus harrisii) numbers in the wild. To ensure its long-term survival, a captive breeding program was implemented but has not been as successful as envisaged at its launch in 2005. We therefore investigated the reproductive success of 65 captive devil pair combinations, of which 35 produced offspring (successful pairs) whereas the remaining 30 pairs, despite being observed mating, produced no offspring (unsuccessful pairs). The devils were screened at six MHC Class I-linked microsatellite loci. Our analyses revealed that younger females had a higher probability of being successful …

Roughly 3% of the Earth's land surface burns annually, representing a critical exchange of energy and matter between the land and atmosphere via combustion. Fires range from slow smouldering peat fires, to low-intensity surface fires, to intense crown fires, depending on vegetation structure, fuel moisture, prevailing climate, and weather conditions. While the links between biogeochemistry, climate and fire are widely studied within Earth system science, these relationships are also mediated by fuels-namely plants and their litter-that are the product of evolutionary and ecological processes. Fire is a powerful selective force and, over their evolutionary history, plants have evolved traits that …

For thousands of years humankind has sought to explore our oceans. Evidence of this early intrigue dates back to 130,000 BCE, but the advent of remotely operated vehicles (ROVs) in the 1950s introduced technology that has had significant impact on ocean exploration. Today, ROVs play a critical role in both military (e.g. retrieving torpedoes and mines) and salvage operations (e.g. locating historic shipwrecks such as the RMS Titanic), and are crucial for oil and gas (O & G) exploration and operations. Industrial ROVs collect millions of observations of our oceans each year, fueling scientific discoveries. Herein, we assembled a group …

Recognition And Management Of Avr Stemi: A Retrospective Cohort Study, Ruan Vlok, Hannah Kempton, Thomas M. Melhuish, Joshua Wall, Astin Lee, Leigh D. White

Faculty of Science, Medicine and Health - Papers: part A

Identification of ST elevation on the electrocardiogram (ECG) is the cornerstone of diagnosis of ST-elevation myocardial infarction (STEMI). While lesion localisation can usually be achieved by regional ST-elevation patterns on ECG, clinicians often neglect changes in the ST segment of lead aVR, possibly contributing to delayed recognition and poorer outcomes for these patients. This study compared the 'door-to-balloon time' and peak troponins - as a surrogate marker of infarct size - for patients presenting with STEMI with ST-segment elevation in aVR compared with those patients without elevation in aVR. A total of 179 patients, including 17 patients presenting with ST-elevation …

Over 60 years ago, stone tools and remains of megafauna were discovered on the Southeast Asian islands of Flores, Sulawesi and Luzon, and a Middle Pleistocene colonization by Homo erectus was initially proposed to have occurred on these islands. However, until the discovery of Homo floresiensis in 2003, claims of the presence of archaic hominins on Wallacean islands were hypothetical owing to the absence of in situ fossils and/or stone artefacts that were excavated from well-documented stratigraphic contexts, or because secure numerical dating methods of these sites were lacking. As a consequence, these claims were generally treated with scepticism. Here …

The Dynamic Topography Of Eastern China Since The Latest Jurassic Period, Xianzhi Cao, Nicolas Flament, R. Dietmar Muller, Sanzhong Li

Faculty of Science, Medicine and Health - Papers: part A

Some changes in the topography of eastern China since Late Jurassic times cannot be well explained by lithospheric deformation. Here we analyze global mantle flow models to investigate how mantle‐driven long‐wavelength topography may have contributed to shaping the surface topography of eastern China. Paleodrainage directions suggest that a southward tilted topography once existed in eastern North China in the latest Jurassic Period, which is different from that at present day (southeastward tilting). Our model dynamic topography reveals a southward tilting topography between 160 and 150 Ma, followed by southeastward tilting and rapid subsidence, which is compatible with paleodrainage directions and …

Interglacial-Glacial Climatic Signatures Preserved In A Regressive Coastal Barrier, Southeastern Australia, Thomas S. Oliver, David Kennedy, Toru Dr Toru Tamura, Colin V. Murray-Wallace, Teresa Konlechner, Paul Augustinus, Colin D. Woodroffe

Faculty of Science, Medicine and Health - Papers: part A

Regressive barriers persisting in the landscape over interglacial-glacial cycles are important repositories of paleoclimatic signatures such as past sea level and regional aridity. The Gippsland region of Victoria contains a multi-barrier system formed during past interglacial-glacial cycles and the late-Holocene. An extensive series of parallel foredune ridges forming the elongate inner barrier was sampled for luminescence dating with ages indicating deposition ca.125,000-108,000 years ago coinciding with the later phase of the Last Interglacial (LIG) Marine Isotope Stage (MIS) 5e and the transition to MIS 5d. Ground Penetrating Radar (GPR) imaged beach-face reflectors within the LIG barrier indicate that sea level …

Weedy plants pose a major threat to food security, biodiversity, ecosystem services and consequently to human health and wellbeing. However, many currently used weed management approaches are increasingly unsustainable. To address this knowledge and practice gap, in June 2014, 35 weed and invasion ecologists, weed scientists, evolutionary biologists and social scientists convened a workshop to explore current and future perspectives and approaches in weed ecology and management. A horizon scanning exercise ranked a list of 124 pre-submitted questions to identify a priority list of 30 questions. These questions are discussed under seven themed headings that represent areas for renewed and …

Demographic Predictors Of Emotional Intelligence Among Radiation Therapists, Stamatia Trakis, Ritin S. Fernandez, Dominique R. Parrish

Faculty of Science, Medicine and Health - Papers: part A

Introduction: Contemporary health care services are more productive and successful when their health professionals have emotional intelligence (EI). The objective of this study was to explore the demographic predictors of EI among radiation therapists working in cancer care centres in NSW, Australia.

Methods: Data were collected using a cross-sectional self-administered survey. Emotional intelligence was measured using the Trait Emotional Intelligence Questionnaire- Short version (TEIQue - SF). Multiple regression analysis was used to identify if age, years of experience, gender, highest level of education obtained or level of current employment were predictors of EI.

Total Synthesis Of Natural Hyacinthacine C5, And Six Related Hyacinthacine C5 Epimers, Anthony Carroll, Kongdech Savaspun, Anthony C. Willis, Masako Hoshino, Atsushi Kato, Stephen G. Pyne

Faculty of Science, Medicine and Health - Papers: part A

The total synthesis of natural (+)-hyacinthacine C₅ was achieved, which allowed correction of its initially proposed structure, as well as six additional hyacinthacine C-type compounds. These compounds were readily accessible from two epimeric anti-1,2-amino alcohols. Keeping a common A-ring configuration, chemical manipulation occurred selectively on the B-ring of the hyacinthacine C-type products through methods of syn-dihydroxylation, S_N2 ring-opening of a cyclic sulfate and also employing either (R)- or (R,S)-α-methylallyl amine for the Petasis borono Mannich reaction. Our small analogue library was then assessed for its glycosidase inhibitory potency against a panel of glycosidases. (-)-6-Epi …

Data stewardship is an essential element of the publication process. Knowing how to enact data polices that are described only in general terms can be difficult, however. Examples are needed to model the implementation of open-data polices in actual studies. Here we explain the procedure used to attain a high and consistent level of data stewardship across a special issue of the journal Climate of the Past. We discuss the challenges related to (1) determining which data are essential for public archival, (2) using data generated by others, and (3) understanding data citations. We anticipate that open-data sharing in paleo …

Faculty of Science, Medicine and Health - Papers: part A

Issue addressed: Health information can be easily and cheaply provided through the Internet. However, we do not know whether older adults, those people most likely to be living with a chronic disease, are online or whether they use the Internet to find health information. Methods: In order to establish the proportion of older Australians online, the impact of their current health status and chronic disease diagnosis on Internet usage and whether they use the Internet to search for health information, a paper-based survey was developed and mailed to 9000 older adults, resident in New South Wales, Australia (response rate = …

Assessing The Chronic Toxicity Of Nickel To A Tropical Marine Gastropod And Two Crustaceans, Francesca Gissi, Jenny Stauber, Monique T. Binet, Melanie Trenfield, Joost Van Dam, Dianne F. Jolley

Faculty of Science, Medicine and Health - Papers: part A

The mining and processing of nickel ores from tropical regions contributes 40% of the global supply. The potential impact of these activities on tropical marine ecosystems is poorly understood. Due to the lack of ecotoxicity data for tropical marine species, there is currently no available water quality guideline value for nickel that is specific to tropical species. In this study, we investigated the toxicity of nickel to three tropical marine invertebrates, the gastropod Nassarius dorsatus, the barnacle Amphibalanus amphitrite, and the copepod Acartia sinjiensis. All toxicity tests used chronic endpoints, namely larval growth, metamorphosis (transition from nauplii to cyprid larvae) …

Despite significant advances toward accurate tuning of the size and shape of colloidal nanoparticles, the precise control of the surface chemistry thereof remains a grand challenge. It is desirable to conjugate functional bio-molecules onto the selected facets of nanoparticles owing to the versatile capabilities rendered by the molecules. We report here facet-selective conjugation of DNA molecules onto upconversion nanoparticles via ligand competition reaction. Different binding strengths of phosphodiester bonds and phosphate groups on DNA and the surfactant molecules al low one to create heterogeneous bio-chemistry surface for upconversion nanoparticles. The tailored surface properties lead to the formation of distinct self-assembly …

Flammability Dynamics In The Australian Alps, Philip J. Zylstra

Faculty of Science, Medicine and Health - Papers: part A

Forests of the Australian Alps (SE Australia) are considered some of the most vulnerable to climate change in the country, with ecosystem collapse considered likely for some due to frequent fire. It is not yet known, however, whether increasing fire frequency may stabilize due to reductions in flammability related to reduced time for fuel accumulation, show no trend, or increase due to positive feedbacks related to vegetation changes. To determine what these trends have been historically, dynamics were measured for 58 years of mapped fire history. The 1.4 million ha forested area was divided into broad formations based on structure …

Animal Host-Microbe Interactions, Bethany J. Hoye, Andy Fenton

Faculty of Science, Medicine and Health - Papers: part A

The ecology of infectious diseases, as we currently recognise it, has been a major field of scientific research for over a century. Since the early work of John Snow, describing the epidemiology of cholera in 1850s London, and Ronald Ross, describing the transmission dynamics of malaria at the end of the 19th century, through the mathematical models of Kermack & McKendrick in the 1920s, and Anderson & May's revolutionary modelling of infectious disease dynamics in the late 1970s, the field of disease ecology has always sought to combine cutting‐edge analytical and theoretical tools with observational and experimental data to understand …

Effect Of Captivity On Morphology: Negligible Changes In External Morphology Mask Significant Changes In Internal Morphology, Stephanie Kirsten Courtney Jones, Adam J. Munn, Phillip G. Byrne

Faculty of Science, Medicine and Health - Papers: part A

Captive breeding programmes are increasingly relied upon for threatened species management. Changes in morphology can occur in captivity, often with unknown consequences for reintroductions. Few studies have examined the morphological changes that occur in captive animals compared with wild animals. Further, the effect of multiple generations being maintained in captivity, and the potential effects of captivity on sexual dimorphism remain poorly understood. We compared external and internal morphology of captive and wild animals using house mouse (Mus musculus) as a model species. In addition, we looked at morphology across two captive generations, and compared morphology between sexes. We found no …

Coarse-Sand Beach Ridges At Cowley Beach, North-Eastern Australia: Their Formative Processes And Potential As Records Of Tropical Cyclone History, Toru Dr Toru Tamura, William A. Nicholas, Thomas S. Oliver, Brendan P. Brooke

Faculty of Science, Medicine and Health - Papers: part A

Storm surges generated by tropical cyclones have been considered a primary process for building coarse-sand beach ridges along the north-eastern Queensland coast, Australia. This interpretation has led to the development of palaeotempestology based on the beach ridges. To better identify the sedimentary processes responsible for these ridges, a high-resolution chronostratigraphic analysis of a series of ridges was carried out at Cowley Beach, Queensland, a meso-tidal beach system with a > 3 m tide range. Optically stimulated luminescence ages indicate that 10 ridges accreted seaward over the last 2500 to 2700 years. The ridge crests sit +3·5 to 5·1 m above Australian …

Does Walkability Contribute To Geographic Variation In Psychosocial Distress? A Spatial Analysis Of 91,142 Members Of The 45 And Up Study In Sydney, Australia, Darren J. Mayne, Geoffrey Morgan, Bin B. Jalaludin, Adrian E. Bauman

Faculty of Science, Medicine and Health - Papers: part A

Walkability describes the capacity of the built environment to promote walking, and has been proposed as a potential focus for community-level mental health planning. We evaluated this possibility by examining the contribution of area-level walkability to variation in psychosocial distress in a population cohort at spatial scales comparable to those used for regional planning in Sydney, Australia. Data on psychosocial distress were analysed for 91,142 respondents to the 45 and Up Study baseline survey between January 2006 and April 2009. We fit conditional auto regression models at the postal area level to obtain smoothed "disease maps" for psychosocial distress, and …

Emissions Of Trace Gases From Australian Temperate Forest Fires: Emission Factors And Dependence On Modified Combustion Efficiency, Elise-Andree Guerette, Clare Paton-Walsh, Maximilien Desservettaz, T E L Smith, Liubov Volkova, Christopher Weston, C P Meyer

Faculty of Science, Medicine and Health - Papers: part A

We characterised trace gas emissions from Australian temperate forest fires through a mixture of open-path Fourier transform infrared (OP-FTIR) measurements and selective ion flow tube mass spectrometry (SIFT-MS) and White cell FTIR analysis of grab samples. We report emission factors for a total of 25 trace gas species measured in smoke from nine prescribed fires. We find significant dependence on modified combustion efficiency (MCE) for some species, although regional differences indicate that the use of MCE as a proxy may be limited. We also find that the fire-integrated MCE values derived from our in situ on-the-ground open-path measurements are not …

Are Underground Coal Miners Satisfied With Their Work Boots?, Jessica Dobson, Diane L. Riddiford-Harland, Alison F. Bell, Julie R. Steele

Faculty of Science, Medicine and Health - Papers: part A

Dissatisfaction with work boot design is common in the mining industry. Many underground coal miners believe their work boots contribute to the high incidence of lower limb injuries they experience. Despite this, the most recent research to examine underground coal mining work boot satisfaction was conducted over a decade ago. This present study aimed to address this gap in the literature by assessing current mining work boot satisfaction in relation to the work-related requirements for underground coal mining. 358 underground coal miners (355 men; mean age = 39.1 ± 10.7 years) completed a 54-question survey regarding their job details, work …

Development Of A Seamless, High-Resolution Bathymetric Model To Compare Reef Morphology Around The Subtropical Island Shelves Of Lord Howe Island And Balls Pyramid, Southwest Pacific Ocean, Michelle Linklater, Sarah Hamylton, Brendan P. Brooke, Scott L. Nichol, Alan Jordan, Colin D. Woodroffe

Faculty of Science, Medicine and Health - Papers: part A

Lord Howe Island and Balls Pyramid are located approximately 600 km offshore of the southeastern Australian mainland, in the subtropical waters of the northern Tasman Sea. Lord Howe Island hosts the most southern coral reef in the Pacific Ocean, and the shelves surrounding both islands feature fossil coral reefs. This study creates a seamless, high-resolution (5 m cell size) bathymetry model of the two shelves to compare and contrast the extent of reef development and shelf morphology. This was produced by integrating satellite-derived depth data (derived to 35 m depth) and multibeam echosounder (MBES) data. Image partitioning and filtering improved …
