Effect of a Water Treatment BMP on Nutrient Spiraling and Leaf Litter Breakdown in an Urban Stream
… compromise valuable ecosystem services, such as nutrient attenuation and carbon processing. A best management practice (BMP) water facility was installed to restore an impaired urban stream in Columbus, GA. This study was conducted to determine the effect of this BMP on nutrient spiraling and …

Sex, Diversity, and Differentiation Within and Between Populations of an Aquatic Hyphomycete
… hyphomycetes contribute to energy flow and nutrient spiraling in rivers by making energy and fixed carbon in autumn-shed leaves available to aquatic invertebrates. These fungi are haploid, predominantly or exclusively asexual, have restricted dispersal abilities, and experience yearly …

Nitrogen spiraling in stream ecosystems spanning a gradient of chronic nitrogen loading
… between nitrogen (N) availability and spiraling (the paired processes of nutrient cycling and advective transport) in stream ecosystems. Anthropogenic activities have greatly increased rates of N loading to aquatic ecosystems. However, streams may be important sites for retention, …

Influence of Multiple Disturbances on Stream Structure and Function
We investigated the influence of multiple disturbances on ecosystem structure and function in a headwater stream adjacent to an abandoned arsenic mine using an upstream (reference) and downstream (mine-influenced) comparative reach approach. In this study, floods were addressed as a pulse …

Influences of Mountainside Residential Development to Nutrient Dynamics in a Stream Network
… system but also aquatic systems by changing the nutrient input from the terrestrial to aquatic. However, the impacts of mountainside residential development on stream ecosystems are complex because interactions between in- stream process and hillslope soils control in-stream nutrient dynamics, …

Linking Heterotrophic Metabolism and Nutrient Uptake in Headwater Streams
… and use of materials, but fundamentally nutrient demand is inherently linked to metabolism based on the stoichiometry of biochemical reactions. The differences between these two groups of organisms confound straightforward regression approaches to quantifying the relationship between …
