Hydrogen peroxide dynamics in an agricultural headwater stream: Evidence for significant nonphotochemical production
Hydrogen peroxide dynamics nonphotochemical production
2014/4/2
Hydrogen peroxide (H2O2
) plays key roles in aquatic systems, including metal redox cycling and degradation
of organic matter into bioavailable forms. Abiotic photoproduction, via photo-oxidation of...

Nitrogen dynamics in grassland streams along a gradient of agricultural development
Nitrogen dynamics grassland streams gradient of agricultural development
2014/4/22
We examined nitrogen (N) uptake in seven grassland streams lying in catchments along a gradient (0-84%) of agricultural land use in New Zealand using a stable isotope (15N) addition of NH4+ to quantif...
Evidence for a delayed response of riverine phosphorus exports from increasing agricultural catchment pressures in the Lough Neagh catchment
riverine phosphorus exports riverine phosphorus exports
2014/4/30
Total phosphorus (TP) exports from the rivers draining into Lough Neagh increased between 1974 and 2000
despite lower TP inputs to the rivers from point sources. Over this period annual diffuse expor...
The influence of watershed land use on lake N : P in a predominantly agricultural landscape
watershed land lake N : P a predominantly agricultural
2014/6/9
This study tests the hypothesis that lakes in watersheds dominated by row-crop agriculture (e.g., maize or soybeans) have systematically higher N: P than lakes in watersheds with large tracts of pastu...
