Current Research

  • Comparisons of mercury and selenium biomagnification rates through aquatic food webs at local and global scales
  • Investigations of hydrological and food-web connectivity between rivers and floodplains in Australia’s wet-dry tropics
  • Evaluations of the importance of natural disturbance and cattle activity on water quality in refugial waterholes of floodplain rivers
  • Creation of new models for the ecological and biogeochemical implications of flood regimes in large rivers
