Rare Metals, EarlyView.ABSTRACT The electrocatalytic reduction of nitrate (NO3ER) has emerged as a promising strategy for mitigating NO3− ${{\text{NO}}_{3}}^{-}$ pollution in wastewater while concurrently producing value‐added ammonia; however, its process is significantly hindered by the lack of highly efficient and low‐cost electrocatalysts. Herein, we proposed several non‐

Nitrification amplifies the decreasing trends of atmospheric oxygen and implies a larger land carbon uptake [PDF]
, 2007 [1] Atmospheric O-2 trend measurements are used to partition global oceanic and land biotic carbon sinks on a multiannual basis. The underlying principle is that a terrestrial uptake or release of CO2 is accompanied by an opposite flux of O-2.

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Denitrification by rhizobia: A possible factor contributing to nitrogen losses from soils [PDF]
, 1980 The intensive pastoral farming system on which New Zealand animal production is based is almost completely dependent upon the rhizobium-legurne symbiosis for the fixed nitrogen required for pasture production.

Organic carbon availability limiting microbial denitrification in the deep vadose zone
Environmental Microbiology, 2018 Microbes in the deep vadose zone play an essential role in the mitigation of nitrate leaching; however, limited information is available on the mechanisms of microbial denitrification due to sampling difficulties.

Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil
Animal Conservation, EarlyView.Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.

Shrinking the Aeration Footprint: Innovative Approaches to Nitrogen Removal in MBR Systems. [PDF]
Water Environ ResMembrane bioreactor pilot study investigates biological treatment within the membrane tank. Performance in terms of effluent concentrations of BOD, sCOD, and ammonia was similar with and without the aeration basin, which suggests that designers of MBR facilities should account for biological processes occurring within the membrane tank.

Nitrate elimination by denitrification in hardwood forest soils of the Upper Rhine floodplain – correlation with redox potential and organic matter [PDF]
, 2002 Denitrification in floodplains is a major issue for river- and groundwater quality. In the Upper Rhine valley, floodplain forests are about to be restored to serve as flood retention areas (polders).
