Short summary
Hall et al. (2013) presented a synthesis of 969 nutrient tracer experiments and used a scaling method to test the hypothesis that nutrient demand is constant with increasing stream size. In this comment we present a reanalysis of a subset of the data used by Hall et al. (2013) and propose that their correlations between nutrient uptake lengths and specific discharge are inadvertently spurious. Therefore, the conclusions derived from such correlations are debatable.
