Murray Darling Freshwater Research Centre



Biogeochemistry & Microbial Ecology

MDFRC supports a team of biogeochemistry ecologists who work in conjunction with scientists and technicians from multiple freshwater disciplines, to deliver high quality scientific research and synthesis.

 These include:

  • Carbon and nutrient dynamics
  • Drought effects on sediments
  • Microbial community analysis
  • Experiments and/or manipulative field trials
  • Mentoring and supervising university students
  • Scientifically analyse data and deliver comprehensive reviews and reports, including reviews and recommendations for management actions

The team also has an interest in:

  • Bacteria and fungi in rivers and streams
  • DNA based technologies
  • Soil and water acidification recovery processes
  • Eutrophication of surface waters
  • Alpine stream ecology
  • Floodplain soils and sediments
