Dr Andrea Walters is an ARC Antarctic Gateway Partnership Postdoctoral Research Associate at the Institute for Marine and Antarctic Studies. She is interested in the role that top and mid trophic level consumer's play in the structure and function of food webs.

Biography

Before commencing her postdoctoral position at the Institute for Marine and Antarctic Studies, Andrea was a Research Assistant at the institute following completion of her postdoctoral studies at the University of Tasmania in 2014.

Expertise

  • Pelagic marine environments
  • Mesopelagic ecology
  • Antarctic and Southern Ocean food webs
  • The management of Antarctic and Southern Ocean ecosystems
  • The use of stable isotope ratios of carbon and nitrogen and marine lipids to characterise the trophic structure of mesopelagic fish assemblages
  • Trophic linkages of marine top predators in Antarctic and Southern Ocean ecosystems

Research Themes

Andrea's research aligns to the University's research theme of Marine, Antarctic and Maritime and is undertaking an active research program within Theme 2 (Open Water and Under Ice Food Webs) in the Antarctic Gateway Partnership. Her research is aimed at building our understanding of environmental controls on mesopelagic organisms in Antarctic and Southern Ocean food webs. Mesopelagics live at depths between 200 and 1000 metres and mediate the transfer of energy from the lower to upper parts of the food webs and connect the upper ocean to the deep abyssal plains on the sea floor. Little is known about the biological and physical determinants that control the distribution of mesopelagic taxa and how these distributions may vary spatially and temporally. Andrea's research is focused on improving our understanding of the ecology of these important mid-trophic level organisms, notably zooplanktivores, by describing key rate parameters such as productivity of zooplanktivores as derived from their prey, and describing their role as prey, particularly related to the foraging by marine mammals and birds. Andrea's research will contribute to a better understanding of the structure and function of mesopelagic components of food webs, and the likely response of mesopelagic species to environmental change.

Collaboration

Andrea is currently involved in three international projects, which are primarily aimed at building our understanding of how Antarctic and Southern Ocean marine food webs respond to environmental change. Combined, these collaborative projects involve partnership between schools of biology at several universities and interdisciplinary research centres across Australia, Europe, South Africa and the United States.
