Flow history explains temporal and spatial variation of carbon fractionation in stream periphyton
temporal and spatial variation carbon fractionation stream periphyton
2014/5/9
We investigated factors that contribute to isotopic carbon fractionation in periphytic biofilms in a human-altered headwater stream with a flashy hydrograph. Water velocity had an important effect on ...
Mass-transfer-limited nitrogen and phosphorus uptake by stream periphyton: A conceptual model and experimental evidence
Mass-transfer-limited nitrogen phosphorus uptake stream periphyton conceptual model experimental evidence
2014/5/19
We conducted flow-tank experiments to examine nitrate (NO3) and dissolved reactive phosphorus (DRP) uptake by stream periphyton over a wide range of near-bed velocities and turbulence levels. Our aims...
Effects of N : P ratio and total nutrient concentration on stream periphyton community structure, biomass, and elemental composition
total nutrient concentration elemental composition

The effects of nutrient ratios on algal community structure and algal growth have been examined extensively in
lakes and marine environments, but rarely in streams. We manipulated stream water N : P ...
