Larger rivers become more influential on network-scale GPP as watershed size increases, but small streams with relatively low productivity disproportionately influence net- work GPP due to their large collective surface area. This production is important because some of it is used for food and some is valued for recreation, it is a direct measure of total ecosystem processes, and it sustains biological diversity.

These studies showed the importance of allochthonous organic matter inputs supporting consumer organisms and gave rise to the generalization that stream ecosystems were heterotrophic (i.e., that respiration exceeded photosynthesis annually, Hynes, 1963; Cummins, 1974).
