▪ Abstract We review the major conceptual developments that have occurred over the last 50
years concerning the factors that influence insect biodiversity in streams and examine how …

Experimental manipulations of fish in a Northern California river during summer base flow
reveal that they have large effects on predators, herbivores, and plants in river food webs …

In population models, omnivorous predation (ie, predation on> 1 trophic level) generally has
a destabilizing influence, whereas habitat heterogeneity tends to stabilize both predatory …

The effects of submerged macrophytes and light on the foraging behaviour and capture rate
of three fishes, perch (Perca fluviatilis), bream (Abramis brama) and roach (Rutilus rutilus) …

Drift activity of stream invertebrates typically is greatest during the nighttime hours in running
waters throughout the world. Such diel periodicity may be an adaptive response that …

Invertebrates that graze periphyton growing on stones in coldwater streams in Michigan are
at greatest risk of predation from a benthic—feeding fish (the mottled sculpin, Cottus bairdi) …

Predation by fish (roach, Hesperoleucas symmetricus, and steelhead Oncorhynchus mykiss)
produced strong cascading effects on biota associated with boulder—bedrock substrates in …

Functional traits and diversity indices have provided new insights into community responses
to stressors. Most traits of aquatic organisms have frequently been tested for predictability …

Disturbance regime is a critical organizing feature of stream communities and ecosystems.
The position of a given reach in the river basin and the sediment type within that reach are …

Freshwater shrimp dominate the faunal biomass of many headwater tropical streams:
however, their role in community organization is unclear. Enclosure/exclosure experiments …
