Document Summary
Succession: the change of the community composition over time. Henry cowle"s (1899) dissertation work on the sand dunes was inspired by european studies describing succession on costal dunes. Cowle"s worked influenced generations of ecologists by defining laws underlying the patterns of change. Cowle"s recognized plant communities as being dynamic, both in species composition and underlying physical environment. (plant communities of different ages in the sand dunes reflected how communities change over time) Sere: a stage in a successional sequence. Categorized in two types based on properties of the habitat on which it occurs. Primary succession: the colonization of habitats devoid of life, occurs in a new habitat with no. These new land systems are caused by volcanism, dune and barrier island formation, and vegetation prior to succession. glaciation. Tend to be slow because of the arduous process of soil development. Secondary succession: occurs in habits following a disturbance, which leaves seeds, spores, or the subterranean portions of plants present.
