Document Summary
Succession bad rep in the 50s and 60s to deterministic of its use: locked into the use of the deterministic process, succession and dynamics used interchangablely. Succession (ecological community dynamics) in its broadest most comprehensive sense is the gradual replacement of one community of organism in an ecosystem by another. Gradual process not aware that it is occurring. Not fully understood why it happens; but it occurs over and over again in ecosystems. There are two broadly recognized types of succession: primary and secondary. Primary succession involves gradual community change on larger extents of land that has been newly created (lava flows)or newly exposed (glacial tills or landslides) Things that happen in primary also happen in the secondary. Gap phase succession a micro succession (occurs on a very small piece of land); variant of second type of succession. Primary succession devolved of life; or newly created; single cell organisms that could stay underground for a long period of time.
