What is the assumption of Clements in colonizing successional species?

#Unit 10. Ecological Principles

possession of space is all-important and that the colonists that get there first determine subsequent community structure, such as facilitation
Early colonists may exclude subsequent colonists such as
Any species can start the succession, but the eventual climax community is reached in a somewhat orderly fashion, such as tolerance
Each colonizing species made the environment a little different, such as facilitation
