Tentative model of microbial interactions with various physical and biological processes in the Apalachicola River estuary (Livingston 1983c). dissolved nutrients into a shallow bay ecosystem characterized by gradients of salinity is seen to provide the appro- priate components for a highly productive system. Tidal and wind-induced currents, periodic flooding, and predation all provide a series of disturbances that, together with the periodic enrichment of the system from upland runoff, increase microbial productivity. River flow and fresh water runoFf from associated wetlands, together with the shallowness of the system and tidal/wind energy subsidies, all contribute to the observed high productivity of the estuary. Considering their immense biomass and their role as processors of nutrients into biologically active material, the microbes are an important component in the energy transformations within the system. 42
