Teaching

Research Interests

  • Effects of climate change and human impacts on the biodiversity, processes, conservation and management of lakes and wetlands.
  • Biological processes in lakes, particularly trophic interactions
  • Plankton ecology
  • Microbial food webs

Mountain and Lake environmentPlease contact me if you are interested in research projects in any of these areas.

  1. Structure and function of microbial food webs in lakes and wetlands, particularly their role:
    a) in carbon transfer up the food chain
    b) as early warning indicators of eutrophication and pollution
    c) nutrient recycling
  2. Biological interactions in lakes with particular reference to:
    a) population dynamics and production of zooplankton
    b) zooplankton distribution (patchiness)
    c) the role of competition, predation and parasitism in structuring zooplankton communities in New Zealand ecosystems
  3. Size-selective processes in aquatic ecosystems, particularly the effects of particle size and concentration on:
    a) selection and retention efficiency by grazers
    b) capture by predators.
    The development and testing of models related to these processes.
  4. Physiological ecology, behaviour and life history strategies of zooplankton, primarily:
    a) the effects of food, temperature and salinity on growth and reproduction
    b) resistance to starvation
    c) the role of chemical inhibitors from cyanobacteria, predators and competitors (allelopathy) in depressing feeding and reproduction.

Current Projects

  • Pelagic processes in lakes, particularly effects on water quality
  • Suspended inorganic sediments and microbial processes
  • Behaviour and life history strategies of freshwater crustaceans
