Spatial and seasonal variations in pigment ratios and gross production:respiration (P:R) ratios were studied at several locations in a small North Carolina stream to determine their relation to a proposed lateral gradient in ecological maturity. Within the limited scope of this study no support was found for the original proposition that the upstream region of the stream was less ecologically mature than the downstream region. If differences in ecological maturity do exist between the two sites studied, they are not properly measured by pigment ratios or P:R ratios, or, more probably, they are overridden by local or edaphic factors.
