Riparian buffer strips influence nitrogen losses as nitrous oxide and leached N from upslope permanent pasture por Dlamini, J.C., Cardenas, L.M., Tesfamarian, E.H., Dunn, R.M., Loick, N., Charteris, A.F., Cocciaglia, L., Vangeli, Sebastián, Blackwell, M.S.A., Upadhayay, H.R., Hawkins, J.M.B., Evans, J., Collins, A.L.

“…Our results also showed that the grass riparian buffer strip is a sink of N2O equivalent to − 2310.2 g N2O-N ha− 1 day− 1 (95% confidence interval:− 535.5 to 492). Event-based water quality results obtained during storms (12 November 2018 and 11 February 2019) showed that the willow riparian buffer treatment had the highest flow-weighted mean N concentrations (N-FWMC) of 0.041 ± 0.022 and 0.031 ± 0.015 mg N L− 1, when compared to the other treatments. …”

Environmental quality and ecotoxicity of sediments from the lower Salado River basin (Santa Fe, Argentina) on amphibian larvae por Peluso, Julieta, Aronzon, Carolina, Martínez Chehda, Agostina, Cuzziol Boccioni, Ana Paula, Peltzer, Paola, De Geronimo, Eduardo, Aparicio, Virginia Carolina, González, Florencia, Valenzuela, Lautaro, Lajmanovich, Rafael

“…Biomarkers of oxidative stress, neurotoxicity and genotoxicity were analyzed in R. arenarum larvae (GS. 25) after exposure (96h) to the complex matrix of water and sediment. The water quality index showed a marginal quality for all sites, influenced mainly by low dissolved oxygen, high total suspended solid, phosphate, nitrite, conductivity, Pb, Cr and Cu levels. …”

Greenhouse gas emissions from natural ecosystems and agricultural lands in sub-Saharan Africa: synthesis of available data and suggestions for further research por Kim, Dong-Gill, Thomas, Andrew D, Pelster, David E., Rosenstock, Todd S., Sanz Cobena, Alberto

“…Rates of all GHG emissions from aquatic systems were affected by type, location, hydrological characteristics, and water quality. In croplands, soil GHG emissions were also dominated by CO2, ranging from 1.7 to 141.2 Mg CO2 ha−1 yr−1, with −1.3 to 66.7 kg CH4 ha−1 yr−1 (−0.04 to 2.3 Mg CO2 eq. ha−1 yr−1) and 0.05 to 112.0 kg N2O ha−1 yr−1 (0.015 to 33.4 Mg CO2 eq. ha−1 yr−1). …”
