  • Work through the tutorial.
  • Vary the initial predator and prey populations to see how subsequent generations are affected.
  • Vary the predator death rates and prey birthrates.
  • Vary predator effectivness.
  • Vary habitat variability and carrying capacity.
  • Can you create scenarios in which one population is completely wiped out within one or two generations? What happens to the other population?
  • Can you create scenarios in which both populations will oscillate indefinitely?
