Abstract
The human microbiome plays an important role in human health. Ecological theory is thought to be important for predicting its functioning. In light of this, recently Coyte et al. have investigated the effects of different compositions of cooperative and competitive interactions between species on the stability of the community. Here I take their model as a reference point. A factor that has not been considered much in this field is the effects of adaptive plasticity of species on the stability of communities. In this report I try to answer the question, how does adaptive plasticity affect the community diversity? Here the generalized Lotka-Volterra model that is used, is analysed using an analytical approach, namely local stability analysis, and a numerical method is used to determine some stable equilibria of different systems. The effects of adaptive plasticity on diversity were found to prevent extinction of species from communities. When looking at the effective interactions that species have while capable of plasticity, it shows that it does not move in a specific direction, i.e., it does not move more toward cooperative interactions.
