OSCILLATING POPULATION GROWTH CURVE OBTAINED BY A SIMULATION MODEL

Abstract

A new mathematical model for analyzing the mechanism of population growth of plants by which simulations could be performed were proposed. In this model, spatial structures of surviving plants and dispersion of seeds were introduced. As a result of simulation performed by using the model, oscillating growth curve whose outline was similar to the logistic curve was obtained. According to the result obtained, the number of plants grew more quickly and the maximum level of growth curve became higher as the number of seeds produced by a plant increased or as the physical length of life was lengthened, and the growth curve had oscillations so far as the physicallength of life was finite.
