Contents Notes
"Procedures outlined in this manual provide an approximate separation of stream macroinvertebrates into Functional Feeding Groups. The objective is to permit a quick initial assessment of the food base of a stream ecosystem by focusing on the functional roles played by the macroinvertebrates present. From 80 to 90% of the organisms encountered can be classified accurately in this way."--P. 1.
