Document Summary

Ecological mechanisms of succession: facilitation, only some species are capable of colonizing new habitat pioneer spp, these species modify the environment and make colonization by other species possible, tolerance, all species can survive. Colonists depend on who gets there first: later arriving species tolerate pioneers, but are better competitors for limited nutrients, inhibition, all species can survive. Colonists depend on who gets there first: pioneer species make the environment less suitable for other species. Facilitation: only some species are capable of colonizing new habitat (pioneer spp, these species modify the environment and make colonization by other species possible. Colonists depend on who gets there first: pioneer species do not modify the environment, species that appear later, arrived later or grew more slowly, later arriving species tolerate pioneers, but are better competitors for limited nutrients. Things that arrive early are not really strong competitive- they are fast growing etc.
