secondary succession → A type of succession that occurs where an existing community has been cleared by some disturbance that leaves the soil intact
ecological succession → Transition in the species composition of a biological community, often following ecological disturbance of the community; the establishment of a biological community in an area virtually barren of life
mutualism → A symbiotic relationship in which the symbiont benefits but the host is neither helped nor harmed
niche → The simple count of number of species in an area.
primary succession → A type of ecological succession that occurs in a virtually lifeless area, where there were originally no organisms and where soil has not yet formed
