The resazurin-resorufin tracer for quantifying respiration and surface water - groundwater interactions in fluvial ecosystems
Abstract
Resazurin is a metabolically active compound that undergoes an irreversible reaction to resorufin in the presence of aerobic respiration. The amount of the reaction is linearly proportional to respiration. Consequently, the compound is useful as an tracer of respiration and groundwater - surface water interactions in fluvial ecosystems. We provide a summary of the development and use of resazurin in these contexts, and illustrate with several field examples.
