Traditional approaches to ecological succession have viewed succession as a gradual change in community composition characterized by a progressive change in species structure, an increase in living and dead biomass and a tendency towards a balance between community production and respiration (Smith 1980). Odum (1969), in his classic paper on ecosystem development, identified 24 attributes of the total system which may be used to determine whether a system is in the early stages of development or approaching the mature, climax stage. In upwelling marine systems there is commonly a period of rapid upwelling of nutrients followed by a period of vertical stability, during which a plankton community may be seen to change from one showing characteristics of early development to one showing more maturity. We were interested in applying network analysis to the upwelling ecosystem at various stages of its development, to see how the indices changed.
