A Review of Membrane Computing Models for Complex Ecosystems and a Case Study on a Complex Giant Panda System

Figure 5

The statistical survival rate, reproduction rate, and mortality rate of endangered giant pandas from GPBB for 13 years from 2005 to 2017, given three group trajectories reflecting the dominant cause of changes in population size: natural factors; human behaviour; or enigmatic factors. The purpose of three graphs is to offer the basis reference for setting parameters in the process of running PDP systems such that the data in Table 3 are tuned on the basis of Figure 5. (a) Survival rate ranges. (b) Reproduction rate ranges. (c) Mortality rate ranges.
