Positive interactions and interdependence in plant communities offers a new look at an old problem ? the nature of the communities. This book marshals ecological literature from the last century on facilitation to make the case against the widely accepted ?individualistic? notion of community organization. Clearly, many species in many communities would not be present without the ameliorating effects of other species. In other words, communities are not produced only by summing the population ecology of species.

This book marshals ecological literature from the last century on facilitation to make the case against the widely accepted individualistic notion of community organization. It examines the idea that positive interactions are more prevalent in physically stressful conditions. Coverage also includes species specificity in facilitative interactions, indirect facilitative interactions, and potential evolutionary aspects of positive interactions.
