The Phosphorus-Chlorophyll 'a' Relationship in Periphytic Communities in a Controlled Ecosystem

摘要

The correlation between toral dissolved phosphorus input concentrations and periphytic chlorophyll a concentrations was examined after a four-week colonization period on artificial substrates in large, continuous-flow microcosms. A significant correlation was established; the data produced a linear regression and substantiated a recently proposed curvilinear regression analysis. The curvilinear equation can be used in future microcosm studies as a predictive aid for regulating phosphorus input concentrations.
