Abstract:
We developed a mathematical model for predator– prey ecosystems undergoing climate-related changes. The model introduces the amount of information transferred between the number of individuals of the predator and prey, and regulation performance in a predator–prey ecosystem is measured by a reduction of Shannon entropy, which is achieved by predation events and decay in the ecosystem. We examine the model with a computer simulation for a well studied bass–crayfish predator–prey ecosystem in a closed lake.
