“…This relationship between slope and P retention indicates that geomorphology is an important factors influencing P retention. Radiotracer studies demonstrated aquatic biota P assimilation in flowing streams (Davis and Foster, 1958;Ball and Hooper, 1961;Elwood and Nelson, 1972), including periphytic algae and aquatic macrophytes (Aiba and Ohtake, 1977). These studies support the premise that bioavailable P forms are the most important to quantify.…”

Phosphorus (P) is often the key nutrient found to be limiting in both estuarine and freshwater ecosystems. As such, the ability of wetlands and streams to retain P is key to determining downstream water quality. This article reviews the processes and factors regulating P retention in streams and wetlands and evaluates selected methodologies used to estimate P retention in these systems. Phosphorus retention mechanisms reviewed include uptake and release by vegetation, periphyton and microorganisms; sorption and exchange reactions with soils and sediments; chemical precipitation in the water column; and sedimentation and entrainment. These mechanisms exemplify the combined biological, physical, and chemical nature of P retention in wetlands and streams. Methodologies used to estimate P retention include empirical input-output analysis and mass balances, and process kinetics applied at various scales, including micro-and mesocosms to full-scale systems. Although complex numerical models are available to estimate P retention and transport, a simple understanding of P retention at the process level is important, but the overall picture provided by mass balance and kinetic evaluations are often more useful in estimating long-term P retention.

“…From Table 12 it is obvious that my results approach some of the lowest primary production rates. Some primary production rates (i.e., Minshall 1967, Elwood andNelson 1972) were lower than those in the Guys Run system, although the streams of each study were similar in size and woodland…”

“…Primary productivity in flowing water systems has been estimated from biomass accumulation on artificial substrates (Kevern & Ball, 1965), open stream oxygen change (Odum, 1956 ;Flemer, 1970 ;Hall, 1972 ;Hoskin, 1959;Kelly, Hornberger & Cosby, 1974) or carbon dioxide change (Wolfe, Cushing & Rabe, 1971;Wright & Mills, 1967), oxygen change in chambers (Hansmann, Lane & Hall, 1971 ;McIntire & Phinney, 1965 ;Pfeiffer & McDiffett, 1975 ;Marker, 1976), 14 C techniques (Naiman, 1976) and 32 P methods (Elwood & Nelson, 1972) .

Carbon dioxide and oxygen exchange procedures for measuring community metabolism (two open stream methods and three chamber methods) were compared on the same reach of a thirdorder stream . Open stream methods were complicated by high diffusion rates and yielded net community primary productivity estimates lower than those obtained with chamber methods . Chamber methods yielded variable productivity and respiration data . However, when normalized for chlorophyll a, productivity estimates from the chamber methods were within an expected range for the system . Balances of photosynthesis and respiration from the chamber methods were similar between methods and indicated that autotrophic or heterotrophic processes could dominate the system . Considerations in applying the various procedures are discussed .
