  • Detecting subtle shifts in ecosystem functioning in a dynamic estuarine environment

    Pratt, Daniel Robert; Lohrer, Andrew M.; Thrush, Simon F.; Hewitt, Judi E.; Townsend, Michael; Cartner, Katie; Pilditch, Conrad A.; Harris, Rachel Joy; van Colen, Carl; Rodil, Iván F. (Public Library of Science, 2015)
    Identifying the effects of stressors before they impact ecosystem functioning can be challenging in dynamic, heterogeneous ‘real-world’ ecosystems. In aquatic systems, for example, reductions in water clarity can limit the ...
  • The effects of short-term increases in turbidity on sandflat microphytobenthic productivity and nutrient fluxes

    Pratt, Daniel Robert; Pilditch, Conrad A.; Lohrer, Andrew M.; Thrush, Simon F. (Elsevier, 2013)
    Turbidity is a major limiting factor of benthic primary production and nutrient uptake on estuarine intertidal sandflats. Estuaries exhibit a wide range of suspended sediment concentrations (SSCs), however, few studies ...
  • Experimenting with ecosystem interaction networks in search of threshold potentials in real-world marine ecosystems

    Thrush, Simon F.; Hewitt, Judi E.; Parkes, Samantha Maree; Lohrer, Andrew M.; Pilditch, Conrad A.; Woodin, Sarah A.; Wethey, David S.; Chiantore, Mariachiara; Asnaghi, Valentina; De Juan, Silva; Kraan, Casper; Rodil, Ivan; Savage, Candida; Van Colen, Carl (Ecological Society of America, 2014)
    Thresholds profoundly affect our understanding and management of ecosystem dynamics, but we have yet to develop practical techniques to assess the risk that thresholds will be crossed. Combining ecological knowledge of ...
  • Quantifying macrodetritus fluxes from a small temperate estuary

    Gladstone-Gallagher, Rebecca Vivian; Sandwell, Dean R.; Lohrer, Andrew M.; Lundquist, Carolyn J.; Pilditch, Conrad A. (CSIRO Publishing, 2017)
    Empirical measurements of estuary-to-coast material fluxes usually exclude the fraction of primary production that is exported as macrodetritus (marine plant litter), potentially leaving a gap in our understanding of the ...
  • Water column turbidity not sediment nutrient enrichment moderates microphytobenthic primary production

    Mangan, Stephanie; Lohrer, Andrew M.; Thrush, Simon F.; Pilditch, Conrad A. (MDPI, 2020)
    Soft sediment intertidal habitats are under intense anthropogenic pressure resulting from increased land derived sediment and nutrient delivery. Long term, this can cause high water column turbidity and nutrient enrichment ...
