Influence of experimental, environmental, and geographic factors on nutrient‐diffusing substrate experiments in running waters

WS Beck, AT Rugenski, NLR Poff - Freshwater Biology, 2017 - Wiley Online Library
Freshwater algal growth is often limited by the availability of nitrogen (N), phosphorus (P), or
both nutrients (NP). For over 30 years, investigators have conducted nutrient‐diffusing …

Effects of N, P, and organic carbon on stream biofilm nutrient limitation and uptake in a semi‐arid watershed

HA Bechtold, AM Marcarelli, CV Baxter… - Limnology and …, 2012 - Wiley Online Library
We examined the effect of agricultural land use on whole‐stream nutrient availability, biofilm
standing crop, and biofilm nutrient limitation and uptake in 21 stream locations in …

Seasonal shifts in the importance of bottom–up and top–down factors on stream periphyton community structure

WS Beck, DW Markman, IA Oleksy, MH Lafferty… - Oikos, 2019 - Wiley Online Library
We examined the importance of temporal variability in top–down and bottom–up effects on
the accumulation of stream periphyton, which are complex associations of autotrophic and …

KA Capps, MT Booth, SM Collins… - Journal of the North …, 2011 - journals.uchicago.edu
Nutrient limitation plays an important role in shaping community structure and ecosystem
processes in aquatic environments. Many types of nutrient diffusing substrata (NDS) have …

Nitrogen fixation and phosphatase activity in periphyton growing on nutrient diffusing substrata: evidence for differential nutrient limitation in stream periphyton

JT Scott, DA Lang, RS King… - Journal of the North …, 2009 - journals.uchicago.edu
We explored N2 fixation and alkaline phosphatase activity (APA) in periphyton from a N-

Nutrient limitation of biofilm biomass and metabolism in the Upper Snake River basin, southeast Idaho, USA

AM Marcarelli, HA Bechtold, AT Rugenski, RS Inouye - Hydrobiologia, 2009 - Springer
It is essential to know the nutrient limitation status of biofilms to understand how they may
buffer uptake and export of nutrients from polluted watersheds. We tested the effects of …
