Nutrient input in streams alters the density and species composition of attached algal communities in open systems. However, in forested streams, the light reaching the streambed (rather than the local nutrient levels) may limit the growth of these communities. A nutrient‐enrichment experiment in a forested oligotrophic stream was performed to test the hypothesis that nutrient addition has only minor effects on the community composition of attached algae and cyanobacteria under light limitation… 
Long‐term moderate nutrient inputs enhance autotrophy in a forested Mediterranean stream
The results show that forested streams subjected to sustained (though minor) nutrient enrichment changed aspects of their biological structure and metabolism and that changes were especially favoured by periods when light was not limiting.
Effects of nutrient enrichment on epipelic diatom assemblages in a nutrient-rich lowland stream, Pampa Region, Argentina
The rising urbanization and agricultural activity in the Pampean plain, may seriously impair the biodiversity of its rivers if the entrance of nutrients to these ecosystems is not mitigated.
Biochemical quality of basal resources in a forested stream: effects of nutrient enrichment
Headwater systems are highly dynamic, and the biochemical composition of the biofilm changed in response to changes in nutrients but also to light in this study, which exemplifies how small land use shifts may affect headwater streams.
How will increased temperature and nutrient enrichment affect primary producers in sub-Arctic streams?
Test hypotheses on the effects of nutrients and temperature on stream primary producers in an alpine geothermal area in SW Iceland found that temperature will directly influence the stream communities, but its secondary effects, manifested through agricultural eutrophication, are likely to be much greater.
Light Increases Energy Transfer Efficiency in a Boreal Stream
It is suggested that even a small increase in light intensity could result in community-wide effects on periphyton in boreal streams, with a subsequent increase in energy transfer and system productivity.
The responses of epilithic algal community structure and function to light and nutrients and their linkages in subtropical rivers
Epilithic algal community structure and function are important indicators of stream ecosystem health and are sensitive to ambient environmental changes. In this study, we examined the impact of light
Variable discharge alters habitat suitability for benthic algae and cyanobacteria in a forested Mediterranean stream.
Large-scale algal community patterns can be understood by studying organisation within patches. Spatial heterogeneity in light and substratum type may affect the biomass and community composition of
Predator-Driven Nutrient Recycling in California Stream Ecosystems
The results suggest that natural and anthropogenic heterogeneity in the relative abundance of these vertebrates and variation in the uptake rates across river networks can affect broad-scale patterns of nutrient limitation.
Aquatic Plant and Dissolved Oxygen Changes in a Reference‐Condition Prairie Stream Subjected to Experimental Nutrient Enrichments
Effects of controlled nutrient additions on a prairie stream were studied using a before‐after‐control‐impact paired design. The site is in a reference condition with low soluble nitrate (NO3) and


Effects of nutrient inputs in a forested mediterranean stream under moderate light availability
Overall, enhanced nutrient availability was able to cause a remarkable biomass increase in the autotrophic component of the stream, in spite of the moderate light availability.
Periphyton Response to Nutrient Manipulation in Streams Draining Clearcut and Forested Watersheds
Algal periphyton in the clearcut stream accumulated more chlorophyll and biovolume than in the forested stream across all nutrient treatments andadequate light resulted in a more architecturally diverse community.
Periphyton response to long-term nutrient enrichment in a shaded headwater stream
We maintained elevated but moderate concentrations of nitrogen and phosphorus continuously for 2 years in a heavily shaded headwater stream and compared effects on stream periphyton with a reference
The influence of substratum type and nutrient supply on biofilm organic matter utilization in streams
The positive relationship between the peptidase activity per cell and the N content of the epilithic biofilm suggested that heterotrophic utilization of proteinaceous compounds from within the biofilm was occurring, and the effect of benthic substratum type and nutrient supply on biofilm structure andheterotrophic metabolism was investigated.
Periphyton response to nutrient addition in 3 lakes of different benthic productivity
Abstract Nutrient-diffusing substrata were used to determine if periphyton communities in lakes of different benthic productivity respond similarly to nutrient inputs, and if their responses
Whole-system nutrient enrichment increases secondary production in a detritus-based ecosystem.
It is demonstrated that positive nutrient-induced changes to food quality likely override negative changes toFood quantity for consumers during the initial years of enrichment of detritus-based stream ecosystems, and that long-term enrichment may impact consumers through eventual reductions in the quantity ofdetritus.
The trophic significance of epilithic algal production in a fertilized tundra river ecosystem
In this experimental river fertilization study, nutrient addition caused shifts in the carbon and nitrogen stable isotope ratios in the biota which provided a unique opportunity to trace organic matter flows and to help determine the effects of fertilization on a tundra river ecosystem.
Responses of chlorophyll-a, organic matter, and macroinvertebrates to nutrient additions in rivers flowing through agricultural and forested land
Results of a 5-6 week field experiment showed that concentrations of chlorophyll-a colonizing NDS varied among rivers and between land use types, and the lack of significant differences between macroinvertebrates inhabiting natural rocks and those colonizing control NDS suggests that similarly designed substrata could be used to monitor macroinVertebrates in microhabitats.
Long‐term responses of the kuparuk river ecosystem to phosphorus fertilization
A long-term stream fertilization experiment was performed to evaluate the potential eutrophication of an arctic stream ecosystem. During 16 years of summer phosphorus (H3PO4) fertilization, we
Nutrient limitation of epilithic and epixylic biofilms in ten North American streams
The results show that biomass responses to nutrient addition by the heterotrophic and autotrophic components of the epixylic biofilm were different, though both experienced the same stream nutrient conditions.
