  • Roudnew, Ben; Seymour, Justin; Jeffries, Thomas; Lavery, Trish; Smith, Renee; Mitchell, James (Wiley, 2012)
    Bacteria and viruses are ubiquitous in subterranean aquatic habitats. Bacterial abundance is known to vary with depth in aquifers; however, whether viral abundance varies with depth is less well known. Here we use flow ...
  • Smith, Renee; Jeffries, Thomas; Roudnew, Ben; Seymour, Justin; Fitch, Alison; Simons, Keryn; Speck, Peter; Newton, Kelly; Brown, Melissa; Mitchell, James (Wiley, 2013)
    Knowledge about viral diversity and abundance in deep groundwater reserves is limited. We found that the viral community inhabiting a deep confined aquifer in South Australia was more similar to reclaimed water communities ...
  • Lavery, Trish; Roudnew, Ben; Seymour, Justin; Mitchell, James; Jeffries, Thomas (Public library of Science, 2012)
    Metagenomic analysis was used to examine the taxonomic diversity and metabolic potential of an Australian sea lion (Neophoca cinerea) gut microbiome. Bacteria comprised 98% of classifiable sequences and of these matches ...
  • Lavery, T; Roudnew, Ben; Gill, Paul; Seymour, Justin; Seuront, L; Johnson, Graham; Mitchell, John; Smetacek, V (Royal Soc London, 2010)
    The iron-limited Southern Ocean plays an important role in regulating atmospheric CO2 levels. Marine mammal respiration has been proposed to decrease the efficiency of the Southern Ocean biological pump by returning ...
  • Smith, Renee; Jeffries, Thomas; Roudnew, Ben; Fitch, Alison; Seymour, Justin; Delpin, Marina; Newton, Kelly; Brown, Melissa; Mitchell, James (Wiley-Blackwell Publishing Ltd., 2012)
    A metagenomic analysis of two aquifer systems located under a dairy farming region was performed to examine to what extent the composition and function of microbial communities varies between confined and surface-influenced ...
  • Jeffries, Thomas; Seymour, Justin; Gilbert, Jack; Dinsdale, Elizabeth; Newton, Kelly; Leterme, Sophie; Roudnew, Ben; Smith, Renee; Seuront, Laurent; Mitchell, James (Public library of Science, 2011)
    Environmental parameters drive phenotypic and genotypic frequency variations in microbial communities and thus control the extent and structure of microbial diversity. We tested the extent to which microbial community ...
  • Roudnew, Ben; Lavery, Trish; Seymour, Justin; Jeffries, Thomas; Mitchell, Jim (Wiley, 2014)
    Standard methodologies for sampling the physicochemical conditions of groundwater recommend purging a bore for three bore volumes to avoid sampling the stagnant water within a bore and instead gain samples representative ...
