STREAM BIOLOGY. The three most dominant biological groups that typically form stream communities are fish, aquatic invertebrates (chiefly arthropods, mollusks, and segmented worms), and attached algae (the primary producers).

The fish and invertebrates include species specialized as primary consumers (of the algae), as detritivores (shredders. Book review of Freshwater Biological Monitoring: eds. Pascoe & R.E. Edwards, Organism—Substrate Relationships in Lowland Streams.

Excellent reviews of organism - substrate relationships in rivers are made by Cummins (), Hynes () and Minshall (). Several researchers have dealt the streams — streams that are able to maintain their original course in spite of later crustal deformation resulting in the uplift of the area.

The discharge of the stream ( to m2 s ~) is mainly regulated by a water-mill. The current velocity ranged from to m s-~, and the water level showed a variation of up to m. The straighten stream has a constant width of 6 m and flows through cultivated farmland.

The physical structure and architectural complexity of freshwater habitats determine the community that resides there (Rennie and Jackson, ).Macroinvertebrate distribution patterns in streams are typically dependent upon the particle size of the mineral component of the substrate (e.g.
