Food Web

The food web of intermittent streams differs from perennial streams in that species number and abundance change drastically among the pre-flow, main flow, and post flow phases. Intermittent streams tend to have a food web based heavily on detritus and follow the bottom-up trophic model. Both the ratios of predator to prey and the number of trophic levels depend on the size of the intermittent stream.
