  • 2016 Subtidal Ecological Survey of Tauranga Harbour and development of benthic health models

    Clark, Dana; Taiapa, Caine; Sinner, Jim; Taikato, Vanessa; Culliford, David; Battershill, Christopher N.; Ellis, Joanne I.; Hewitt, Judi E.; Gower, Fiona; Borges, Hugo; Patterson, Murray (Massey University, 2018)
    This report summarises the results of biological and physical data collected from a broad-scale subtidal survey of Tauranga Harbour conducted between March and May 2016. The survey was designed to understand more fully the ...
  • 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 ...
  • Ecological Survey of Tauranga Harbour

    Ellis, Joanne I.; Clark, Dana; Hewitt, Judi E.; Taiapa, Caine; Sinner, Jim; Patterson, Murray; Hardy, Derrylea; Park, Stephen; Gardner, Bruce; Morrison, Alice; Culliford, David; Battershill, Christopher N.; Hancock, Nicole; Hale, Lydia; Asher, Rod; Gower, Fiona; Brown, Erin; McCallion, Aaron (Cawthron Institute, 2017)
    This report summarises the results of biological and physical data collected from a broad scale intertidal survey of Tauranga Harbour conducted between December 2011 and February 2012. The survey was designed to understand ...
  • Effect of nutrient enrichment and turbidity on interactions between Microphytobenthos and a key bivalve: implications for higher trophic levels

    Hope, Julie A.; Hewitt, Judi E.; Pilditch, Conrad A.; Savage, Candida; Thrush, Simon F. (Frontiers Media SA, 2020)
    Benthic diatoms are a high-quality food resource providing essential fatty acids to benthic grazers. Different stressors may alter the proportion of diatoms and other microalgae and thus can affect the quality as well as ...
  • 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 ...
