 Abstract

Interactions between structure and function can take place among various spatiotemporal scales, and point-measures integrate across space to create a comprehensive assessment of longitudinal function. Using measures of aquatic benthic biomass, hydrology, stream metabolism, and dissolved solutes in the Upper Clark Fork River (UCFR) in western Montana, a hierarchical model was employed to understand biogeochemical function at increasing spatial scales. Although individual sites exhibited distinct differences in the abundance of benthic biomass, metabolic character, and nutrient availability, integrated measures at the reach-scale suggests a sustained capacity for the biological processing of nitrate (NO3-N). Relationships between changes in NO3-N
