Document Summary
If you make changes to the environment, what ramifications will happen to the community. Two views of communities: super organism: tightly evolved, interacting, functions as a whole organism, developmental progression through succession. This is an older view but reflects what conservation is based on: individualistic view: randomly assembled, similar resource requirements, a lot of competition but outcomes are not predictable. Succession is the theory of super organism where interactions create a sense of predictability. A stable equilibrium is assumed and aims to predict community change over time. Clements: assumed that a climax vegetation is achieved. Creation of a bare area allows species to move in and establish. These organisms then establish more organisms at the site, increasing interactions at the site. Modification of the site by these organisms changes. Biol3007 the relative ability of species to establish and survive. New organisms comes in and this continues until a stable climax is reached.
