A field experiment with a factorial design was used to examine changes in benthic periphyton exposed to different regimes of scouring (scoured/non-scoured), light (open/shaded), and grazing (grazed/non-grazed) to investigate the role of environmental heterogeneity in shaping assemblages of periphyton in Rocky Mountain streams. Clay tile substrata were positioned at the start of the experiment either in the main channel (to receive bedload scouring) or a protected side channel (where scouring… 

Effects of shading on calcareous benthic periphyton in a short-hydroperiod oligotrophic wetland (Everglades, FL, USA)

The effects of shade on benthic calcareous periphyton were tested in a short-hydroperiod oligotrophic subtropical wetland (freshwater Everglades). The experiment was a split-plot design set in three

Disturbance-Mediated Effects of Fishes on Stream Ecosystem Processes: Concepts and Results from Highly Variable Prairie Streams

Stream fishes can have strong top-down and bottom-up effects on ecosystem processes. However, the dynamic nature of streams constrains our abil - ity to generalize these effects across systems with

How do abiotic environmental variables shape benthic diatom assemblages in subtropical streams

The spatial difference observed in the benthic diatom assemblages was predominantly driven by proximate environmental drivers, which, in turn, were affected by ultimate drivers.

Abiotic autumnal organic matter deposition and grazing disturbance effects on epilithic biofilm succession.

It is suggested that algal priming promoted a shift in ambient biofilms but that this effect is dependent upon successional timing of algal establishment, and implies that leaf litter deposition may have bottom-up effects on the stream ecosystem through altered epilithic bio Films.

Abiotic controls on periphyton accrual and metabolism in streams: Scaling by dimensionless numbers

Increasingly available high‐resolution topographic data from remote sensing motivates the search for topographic features that predict abiotic controls on the distribution and performance of biota.

Factors driving diversity and succession of diatom assemblages in a Neotropical rainforest stream

The results underscore the importance of diatom diversity in Neotropical streams and the relevance of small variations in environmental factors on the composition of reference assemblages of Neotropic fluvial systems.

Will Stream Periphyton Respond to Increases in Light Following Forecasted Regional Hemlock Mortality?

ABSTRACT The hemlock woolly adelgid invasion is expected to cause widespread mortality of eastern hemlock (Tsuga canadensis) throughout much of New England. Light levels in streams with hemlock

Comparing herbivory effects of stream macroinvertebrates on microalgal patch structure and recovery

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.

Abstract The presence, abundance, composition, and growth of periphyton are controlled or influenced by 5 broad classes of environmental variation: disturbances, stressors, resources, hydraulic



Light and a Grazing Mayfly Shape Periphyton in a Rocky Mountain Stream

In subalpine streams, light may be instrumental in establishing periphytic structure and in modifying the impact that grazers have on algae, although species assemblages differed between light treatments.

Does an increase in irradiance influence periphyton in a heavily-grazed woodland stream?

Results from this study indicated that limitation of periphyton photosynthesis could be mitigated by increasing the levels of an abiotic resource to this system, but that perip Hyton biomass was controlled by biotic interactions.

Does light intensity modify the effect mayfly grazers have on periphyton

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.

Community organization in streams: the importance of species interactions, physical factors, and chance

Examination of the mechanisms governing the distribution and abundance of two major patch types in unshaded reaches of Augusta Creek, Michigan demonstrates how interactions between competition, predation, and physical factors can generate a complex mixture of community patterns.

Light limitation in a stream ecosystem: responses by primary producers and consumers

Bottom-up effects of light limitation were propagated very strongly in WOC, where the invertebrate fauna is dominated by a grazer that appears to escape top-down control.

Grazers and Nutrients Simultaneously Limit Lotic Primary Productivity

Although nutrient effects on periphyton ash-free dry mass were statistically insignificant, nutrient additions significantly increased chlorophyll a, especially where snails were excluded, and Photosynthesis–irradiance data suggested that nutrient enrichment increased self-shading in the peripHYton.

Resource stress alters hydrological disturbance effects in a stream periphyton community

Scouring reduces stream periphyton biomass during floods, and levels of light and nutrient resource supply can influence growth and community physiology between floods. We hypothesised that for a

Interactions among irradiance, nutrients, and herbivores constrain a stream algal community

It is demonstrated that algal biomass and productivity can be under multiple constraints by irradiance, nutrients, and herbivores and indicates the need to employ multifactor experiments to test for such interactive effects.

Herbivory and irradiance shape periphytic architecture in a Swiss alpine stream

Algal responses were most pronounced under grazing by Ecdyonurus, which was associated with decreases in the abundance of six of the seven algal physiognomies, which suggest that understanding periphytic community responses to grazing will require more sophisticated models of perip hytic structure.

Some effects of current velocity on periphyton communities in laboratory streams

SummarySome effects of current at velocities of 9 and 38 cm/sec on periphyton communities have been determined in laboratory streams.The diatom community that developed in the faster current formed a
