Fish foraging effects on benthic assemblages along a warm-temperate stream: Differences among drift feeders, benthic predators and grazers

Article Abstract:

Fish forgaging effects on periphyton and benthic invertebrates changing along a longitudinal gradient of a warm-temperate stream in southwestern Japan are examined. A subsequent enclosure experiment showed that the reduction of invertebrate densities at the lower site is caused by the grazers rather than benthic intevertebrate feeders.

Direct and indirect effects of UV radiation on benthic communities: epilithic food quality and invertebrate growth in four montane lakes

Article Abstract:

The direct effects of ultraviolet radiation (UVR) on benthic invertebrates and epilithon are investigated. The indirect effect of ultraviolet radiation (UVR)-mediated shifts in epilithic food quality on epilithic consumers is examined.
