Effects of competition and facilitation on species assemblage in two types of tropical cloud forest.

Competition and facilitation between tree individuals are two kinds of non-random processes influencing the structure and functioning of forest communities, but how these two plant-plant interactions change along gradient of resources or environments remains very much a matter of debate. We develope...
