The Annual Pattern and Spatial Distribution of Aquatic Oxygen Metabolism in Boreal Forest Watersheds
The level and diversity of metabolism in lotic ecosystems are largely functions of channel geomorphology and hydrology, making site—specific studies difficult to extrapolate to other parts of the watershed. This paper describes the pattern and distribution of aquatic oxygen metabolism for undisturbe...

Metabolism by periphyton, mosses, macrophytes, fine particulate organic matter (FPOM: 0.5 μm—1mm), an coarse particulate organic matter (CPOM: >1mm) was examined during the ice—free period (April to November) of 1979 and 1980 in First Choice Creek (first order; watershed area: 0.25 km 2 ), Beaver Creek (second order; 1.83 km 2 ), Muskrat River (fifth order; 207 km 2 ), matamek River (sixth order; 673 km 2 ), and the Moisie River (ninth order; 19 871 km 2 ).
