BIOL 2200 Lecture Notes - Seabed Gouging By Ice, Climax Community, Regular Sequence
Document Summary
When glaciers receded they left large chunks of ice in the ground which melted and created kettle lakes. These lakes fill in, the plants around the edge of the lake begin to build over the water and enclose the lake. We call them disturbances and they happen all the time. Dune blowout (all vegetation will be blown out, sand will replace it) A regular sequence of changes in the species composition of a community in a newly formed or disturbed habitat that progresses to a stable state. Progresses to a state of no change, will remain in balance for a long time. A series of stages of community change leading toward a stable state: different seres can lead to same endpoint. There can be other patterns that lead us to stability. Understand that we can start with an aquatic system, dune grasses or aster- goldenrods: there are different ways to get to the same final point.
