Summary
A growing body of work demonstrates that arbuscular mycorrhizal fungal communities can be diverse and that individual fungal species within fungal communities are ecologically distinct. Specifically, arbuscular mycorrhizal fungi (AMF) have been shown to differ in their effect on plant hosts and differ in their response to plant hosts. The mutual interdependence of plant and AMF relative growth rates can result in an active dynamic interaction between plant and AMF communities. In this chapter, we describe two possible types of dynamics: that of positive feedback and that of negative feedback. In the case of positive feedback, initial differences in the community composition are reinforced and the dynamic is predicted to lead to the loss of diversity from the community. In the case of negative feedback, the dynamic between the plant and fungal community directly contributes to the maintenance of diversity within both communities.
