If water flows through the channel throughout the year, the river or stream is called a perennial stream. 15:399–405. Most float freely and are therefore unable to maintain large populations in fast-flowing water. Much of the primary production within the channels of streams and rivers, particularly those with fast flowing water, is typically restricted to benthic habitats involving algae and cyanobacteria. The most widely cited studies concerning the energetics of lotic systems have been conducted on headwater streams in temperate deciduous forested regions. Effect of simulated canopy cover on regulation of nitrate uptake and primary production by natural periphyton assemblages. J. Bot 49:75–87. ), The dynamics of lotic systems. 1967. Food Web: Headwater streams provide a great resource base for productivity of stream food webs, providing food for animals living within the stream as well as food for animals living further downstream. This production is important because some of it is used for food and some is valued for recreation, it is a direct measure of total ecosystem processes, and it sustains biological diversity.
