4. Discussion
To the authors’ knowledge, this study presents the first basin-scale analysis of allometric scaling of hyporheic respiration. Our analysis demonstrates considerable variability in scaling relationships, both within and across the study basins, but also suggests some common responses, which provides initial evidence that some aspects of hyporheic respiration allometry may generalize across basins. Below, we discuss where we found consistent relationships, where we did not, potential connections to watershed characteristics, limitations of our approach, and future research directions.
