The effects of grazing on algal assemblages by three different stream herbivores, the mayfly Centroptilum elsa, the snail Juga silicula, and the caddisfly Dicosmoecus gilvipes, were studied during a 48-d experiment in six laboratory streams. Compared with ungrazed control streams, grazing by Centroptilum (500/m2) modified algal community structure slightly but had little effect on periphyton biomass and chlorophyll a. Grazing by Juga (350/m2) reduced periphyton biomass and chlorophyll a by… 
Temporal patterns of grazer-periphyton interactions in laboratory streams
TLDR
The patchy grazing patterns of Juga and Baetis resulted in more diverse algal assemblages than either the Dicosmoecus grazed or ungrazed streams, and the temporal and spatial pattern of grazing relative to the developmental stage of the periphyton may contribute to maintaining a mosaic of algal patches in different serai stages.
Influence of grazer type and abundance on plant-herbivore interactions in streams
TLDR
Grazer-periphyton interactions were investigated in 11 laboratory streams holding a range of densities of three herbivore taxa during a 32-d experiment, suggesting that high grazing pressure, regardless of taxon, will similarly affect peripHYton.
Effects of Herbivore Type and Density on Taxonomic Structure and Physiognomy of Algal Assemblages in Laboratory Streams
TLDR
It is concluded that grazing can substantially influence algal growth form and assemblage physiognomy in lotic ecosystems.
Independent and interactive effects of nutrients and grazers on benthic algal community structure
TLDR
Significant interactive effects of P and grazing by Helicopsyche indicated that both nutrient addition and grazing may exert significant impact on algal communities, however, grazing may have a much stronger effect on algae than nutrients.
Facilitation of periphyton production by tadpole grazing: functional differences between species
TLDR
Path analyses indicated that Rana affected macroinvertebrates via both interference and exploitation of epiphytic diatoms, and the differences in effect between the two species were probably due to their roles as consumers rather than as recyclers.
Stream periphyton response to grazing and changes in phosphorus concentration
TLDR
A model that includes grazing was calibrated to the data and produced a reasonable expectation of periphyton biomass over a range in SRP concentrations, while the model with constant grazer abundance predicts a gradually increasing grazed biomass as SRP increases.
Food Limitation Affects Algivory and Grazer Performance for New Zealand Stream Macroinvertebrates
We studied herbivory and grazer performance (i.e., fitness correlates) for the hydrobiid snail Potamopyrgus  antipodarum, the leptophlebiid mayfly Deleatidium spp., and the conoesucid caddisfly
Does light intensity modify the effect mayfly grazers have on periphyton
TLDR
Although both mayfly taxa influenced periphytic community structure, physiognomy was not a good predictor of algal susceptibility to grazing, and type of substratum to which an algal filaments vs hard surfaces and location within the peripHYtic matrix may be better indicators of vulnerability to grazing.
Comparing herbivory effects of stream macroinvertebrates on microalgal patch structure and recovery
TLDR
Herbivory primarily by Potamopyrgus affected microalgal patch structure, and hence the starting successional sere, but had no detectable effect on short‐term successional direction in these fast‐recovering communities.
Grazing impact of two aquatic invertebrates on periphyton from an Andean-Patagonian stream
TLDR
Results showed that the herbivores contrasted in their mouthpart morphology and foraging behaviour but would play a similar ecological role, since they both can be considered as scrapers.

TLDR
The effects of grazing by snails on community structure of periphyton were studied in laboratory streams and grazing had no effect on the percentage of chlorophyll a in ash-free weight.

Are snails important competitors in stream ecosystems of the Pacific Northwest (USA)
TLDR
Analysis of benthic samples from 20 stream reaches showed that densities of many invertebrate taxa were inversely correlated with snail density, and Juga appears to be a competitive dominant in some streams and may profoundly influence both abundances of individual species and community structure.
Effects of irradiance on the community structure and biomass of algal assemblages in laboratory streams
TLDR
Streams were used in a replicated, experimental design to investigate whether differences in algal biomass, taxonomic structure, and physiognomy result from exposure to different irradiances, and it was indicated that the successional trajectories of assemblage...

Foraging and resource patchiness: field experiments with a grazing stream insect
TLDR
An assessment of the rate of periphyton removal effected by grazers in this habitat, relative to resource renewal rates, suggests that peripHYton is a limiting resource for which D. gilvipes larvae compete exploitatively.

TLDR
Although the laboratory systems had many species in common during the realy stages of colonization, the experimental treatments generated differences in rates of community development, and the applicability of traditional successional theory to develoopmental patterns in lotic periphyton assemblages is discussed.
