The blue line of a river on a map conveniently represents rivers as two-dimensional habitats beginning (usually) in a mountainous region, and ending in a far-off sea (or inland basin). But the physical changes in three dimensions along a river’s length have important implications for river inhabitants.
River sources are usually small, and in the case of mountain streams, steep and erosional (Montgomery and Buffington 1997). In temperate environments, small streams tend to be shaded by an interlocking, overhead tree canopy. Such conditions result in cool, well oxygenated streams that are abundantly supplied with a food base of leaves. Fine particles of organic
