This paper reports results of experiments to determine the influence of microbes associated with decomposing leaf detritus on the uptake length and retention of phosphorus in a heterotrophic stream. The purposes were to (1) determine the relationship between the biomass and activity of microbes associated with decomposing leaf detritus and the uptake length of PO/sub 4/-P in a stream; (2) compare the temporal pattern in the uptake rate of phosphorus among species of leaves that have been shown to differ in their rate of decomposition as a function of time in a stream; and (3) examine the temporal patterns in the net accumulation, leaching, and transformations of phosphorus in flow-through systems containing decomposing leaf detritus.
