Evidence That Hyporheic Zones Increase Heterotrophic Metabolism and Phosphorus Uptake in Forest Streams

We used nondisruptive, whole-stream methods to measure hydraulic characteristics, ecosytem metabolism, and phosphorus cycling in the west fork of Walker Branch (WB), Tenessee and in Hugh White Creek (HWC), North Carolina. Although Similar in many of their hydrological and chemical characteristics, t...

Description
Summary:We used nondisruptive, whole-stream methods to measure hydraulic characteristics, ecosytem metabolism, and phosphorus cycling in the west fork of Walker Branch (WB), Tenessee and in Hugh White Creek (HWC), North Carolina. Although Similar in many of their hydrological and chemical characteristics, transient storage zone volume in HWC was relatively large ($\thicksim 1.5$times that of the flowing water zone), whereas transient storage zone volume in WB was small ($\thicksim 0.1$times that of the flowing water zone). Both streams were highly heterotrophic (gross primary production: total respiration ratios
