Fig. 2
Competition between two types of prey under different carrying capacities. The parameter values are from Table 1 unless stated otherwise. The initial population density is [2, 2, 0, 1]. A Carrying capacity K equals 13. B Carrying capacity K equals 20, causing higher density of each population and shorter reversal time Tw compared to the case that K equals 13. C Carrying capacity K equals 9, the PA prey wins the competition. D The relationship between the reversal time Tw and carrying capacity K.
