Dr Neil Pettit

Neil is a Research Fellow within the School of Science working on a Office of Water Science project investigating the ecohydrology of groundwater dependent terrestrial vegetation in terms of responses to coal seam gas extraction and coal mining.

Background

  • Research Fellow, Centre of Excellence in Natural Resource Management, University of Western Australia.  Research on Australian tropical rivers, food webs and floodplain connections
  • Research Scientist, School of Aquatic and Fishery Sciences, University of Washington, Seattle USA.  Research on river vegetation dynamics as part of the River/Savanna Boundaries Program (RBSP) in Kruger National Park, South Africa.
  • Post-Doctoral Fellow at the Australian Centre for Tropical Freshwater Research, James Cook University, Townsville North Queensland.  This position mainly involved an investigation of the ecological effects of livestock grazing on riparian vegetation in the Burdekin River catchment.

Professional Associations

  • Australian Society of Limnology (1996 – present).

Research Areas and Interests

Neil’s research interests include riverine vegetation ecology at a community and population level as well as more general research interests including riparian vegetation dynamics, the effects of altered flow regimes on riparian vegetation and general ecological processes in freshwater aquatic systems.  Other areas of interest include understanding ecological processes in freshwater aquatic ecosystems, particularly importance of variability and links between biogeochemistry and food webs and how this can inform natural resource management and development.
