Document Summary
Mechanisms of autogenic succession: how species interactions shape community dynamics. Ends up at climax community through interactions between species (herbivory, competition, predation, facilitation). Disturbance takes place, who gets in there and what is the process of getting back to where we were. Facilitation: one species helps another species later in the succession. Inhibition: one plant prevents the maturation of another one (e. g. shading out of another species). Trade off, either good colonizer or good competitor. Weeds are known as early colonizers: grow really quickly and not very competitive. Trees are late successional species: don"t grow quickly and are very competitive. Beech tree is a dominant species and cast shadow (good competitor), but has very short dispersal options. Other species, such as red maple aren"t good competitors (can"t cast shadow) and has very good dispersal. Mutualism: both species benefits from an interaction (e. g. cleaner fish).
