Simulating the dynamic relationship between predators and prey (based on Lotka-Volterra)
R = # Prey
P = # Predators
a = Growth rate of R
b = Death rate of R (due to P)
e = Efficiency of converting R into P
c = Death rate of P
Computer Simulation in Ecology
This collection of mathematical simulations is intended to give you the opportunity
to work with mathematical modeling in ecology. Mathematical models are useful
tools to understand the dynamic nature of interacting factors.
