Continuous time is modelled using differential equations. Discrete time is modelled using difference equations. These model ecological processes that can be described as occurring over discrete time steps. Matrix algebra is often used to investigate the evolution of age-structured or stage-structured populations. The Leslie matrix, for example, mathematically represents the discrete time change of an age structured population.Grant WE (1986) Systems analysis and simulation in wildlife and fisheries sciences.
