facilitation
1. The intensification of a behaviour that is caused by the presence of another animal of the same species.
2. The process whereby a plant so modifies a habitat as to allow other species to invade (as in a succession). For example, the grass Elymus farctus facilitates the invasion of Ammophila arenaria (marram grass) in the early stages of sand-dune formation. If the invader is more efficient in the new circumstances, this may lead to the decline and eventual exclusion of the facilitating species. Compare inhibition.
