Periphyton Communities in Streams of the Ozark Plateaus and Their Relations to Selected Environmental Factors.

摘要

The purpose of this report is to present relations between periphyton (within this report defined as attached benthic algae, including blue-green algae or cyanobacteria) community characteristics, and physical, chemical, and biological factors for representative sections (reaches) of selected Ozark Plateaus (Ozark) streams. A limited discussion of macroalgae (primarily attached or floating filaments) abundance and distribution among Ozark streams is included in this report. The emphasis of the NAWQA Program is water quality; hence, the relation of periphyton communities to water quality is an important focus of this report. However, periphyton community characteristics related to water quality must be considered in conjunction with differences in other physical and biological factors because these factors are known to affect periphyton communities in streams.
