Predator–Prey Dynamics

Simulate Lotka-Volterra predator–prey oscillations. Adjust growth rates and interaction coefficients to see how predator and prey populations cycle.

Parameters

Key Concepts

  • • dH/dt = rH − aHP: prey grow exponentially, limited by predation
  • • dP/dt = bHP − mP: predators depend on prey for births, die at rate m
  • • Populations oscillate: prey peak → predator peak (with time lag)
  • • Equilibrium: H* = m/b, P* = r/a
  • • Classic example: Canadian lynx and snowshoe hare (Hudson Bay Company data, ~10-year cycle)
