Ecosystem dynamics and resilience

Abstract A seminumerical method is introduced which solves the equations of population dynamics with environmental or demographic stochastic influences. By this method it is shown that random influences on population dynamics showing multiple stability change the deterministic results completely. A metastable state showing temporal constancy for a finite period is found. This shows some relationship to both the deterministic result and the final stochastic state. The ecological consequences of metastability are discussed.
