Experimental evidence of a low-oxygen refuge for large zooplankton
Experimental evidence a low-oxygen refuge large zooplankton
2014/4/4
We tested the hypothesis that hypoxic zones in the metalimnion and hypolimnion of lakes can provide a refuge against fish predation for large zooplankton. Experiments were run in a large indoor mesoco...
Experimental evidence that pollution with urea can degrade water quality in phosphorus-rich lakes of the Northern Great Plains
pollution urea degrade water quality phosphorus-rich lakes the Northern Great Plains
2014/4/17
Urea is the most abundant nitrogen (N) fertilizer used on agricultural soils, yet its effects on adjacent aquatic ecosystems are largely unknown. Here 21-d, 3000-liter mesocosm experiments were conduc...
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...
Experimental evidence for linkages between infaunal recruitment, disturbance, and sediment surface chemistry
Experimental evidence infaunal recruitment sediment surface chemistry
2014/5/26
In prior studies, we have argued that changes in sediment surface chemistry driven by biotic and physical disturbance affect recruitment decisions of infauna. Here, we provide additional data for oxyg...
