▪ Abstract Animals are important in nutrient cycling in freshwater ecosystems. Via excretory
processes, animals can supply nutrients (nitrogen and phosphorus) at rates comparable to …

Phosphorus (P) supply (concentration and flux) is an important driver for biological activity in
flowing waters and needs to be managed to avoid eutrophication impacts associated with …

Stream Ecology: Structure and Function of Running Waters is designed to serve as a
textbook for advanced undergraduate and graduate students, and as a reference source for …

In many aquatic ecosystems, most microbes live in matrix-enclosed biofilms,, and contribute
substantially to energy flow and nutrient cycling. Little is known, however, about the coupling …

Over the past 3 decades, nutrient spiraling has become a unifying paradigm for stream
biogeochemical research. This paper presents (1) a quantitative synthesis of the nutrient …

Eutrophication caused by phosphorus (P) leads to water quality problems in aquatic
systems, particularly freshwaters, worldwide. Processing of nutrients in shallow habitats …

The effects of nutrient ratios on algal community structure and algal growth have been
examined extensively in lakes and marine environments, but rarely in streams. We …

Stream ecosystems consist of several subsystems that are spatially distributed
concentrically, analogous to the elements of a simple telescope. Subsystems include the …

The Lotic Intersite Nitrogen eXperiment (LINX) was a coordinated study of the relationships
between North American biomes and factors governing ammonium uptake in streams. Our …

Abstract Fourier Transform Infrared (FT-IR) microspectroscopy provides an in situ,
nondestructive chemical analysis of individual algal cells. Algae play key roles in nutrient …
