In this model, soil communities are stable systems. In reality, however, soil
communities may be dynamically changed, which consequently influences both
soil community and plant species. For example, one common impact on soil
communities comes from microbial immigration and dispersion. Dispersion may
weaken the influence of plants on soil microbes, then our model should underestimate the delay brought by randomness. Does change of soil community over time
affect plant coexistence? The model above provides a basis to answer this question.
You can also use the model to capture the density dependence of feedback effect.
