Theoretical Studies on the Effects of Dispersal Corridors on the Permanence of Discrete Predator-Prey Models in Patchy Environment
Figure 4
The dynamics of models (38) and (39) subject to (41). (a) is the dynamics of (38). It is observed that the predator in patch 1 will go to extinction. (b) is the dynamics of (39). It is observed that the predator in patch 1 is permanent now due to the dispersal corridors, and (39), as a whole, is permanent. The black solid (dotted) line is the population variation of the prey in patch 1 (patch 2). The green solid (dotted) line is the population variation of the predator in patch 1 (patch 2).
