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.
