Continuous-time biological models including epidemic models and a competition population model are presented. Nonstandard finite difference methods are then applied to approximate these continuous-time systems. The resulting difference equations are studied and comparisons between continuous-time and discrete-time models are made. In particular, conditions for the existence and stability of steady states are investigated. Numerical simulations of the discrete approximations are also presented.
