The Stability of Predator-Prey Systems

摘要: The interactions between a predator and prey species have been analyzed by computer simulation of model in which there are discrete breeding seasons, separated winter during the must be able to find at certain minimum rate or starve. is intended represent warm-blooded vertebrate its prey. main conclusions are: (1) Coexistence possible, but if so, number present will not substantially below equilibrium absence predators. Mutual regulation prey, with latter carrying capacity environment, unstable. (2) more likely differences hunting ability different individual predators-for example, young old (3) Cover for enables survive extinction predator, does make coexistence likely.
