The metabolic regimes of 356 rivers in the United States
(Nature Publishing, 2018-12-11)
A national-scale quantification of metabolic energy flow in streams and rivers can improve understanding of the temporal dynamics of in-stream activity, links between energy cycling and ecosystem services, and the effects ...
New Insights on Arabidopsis thaliana Root Adaption to Ammonium Nutrition by the Use of a Quantitative Proteomic Approach
(MDPI, 2019-02-14)
Nitrogen is an essential element for plant nutrition. Nitrate and ammonium are the two major inorganic nitrogen forms available for plant growth. Plant preference for one or the other form depends on the interplay between ...
Molecular and biochemical analysis of XDH from Phaseolus vulgaris suggest that uric acid protects the enzyme against the inhibitory effects of nitric oxide in nodules
(Elsevier, 2019-09-05)
Xanthine dehydrogenase (XDH) is essential for the assimilation of symbiotically fixed nitrogen in ureidic legumes. Uric acid, produced in the reaction catalyzed by XDH, is the precursor of the ureides, allantoin and ...
Effects of multiple stressors associated with agriculture on stream macroinvertebrate communities in a tropical catchment
(Public Library Science, 2019-08-08)
Tropical forests are declining at unprecedented rates in favour of agriculture, and streams can be severely impacted due to effects of multiple stressors that have rarely been considered together in tropical studies. We ...
Can Ammonium Stress Be Positive for Plant Performance?
(Frontiers Media, 2019-09-24)
Ammonium (NH3/NH+4) nutrition is considered as a universal stressful situation (recently reviewed in Li et al., 2014; Esteban et al., 2016; Liu and Von Wirén, 2017). Briefly, the most common symptom of ammonium nutrition ...
Providing carbon skeletons to sustain amide synthesis in roots underlines the suitability of Brachypodium distachyon for the study of ammonium stress in cereals
(Oxford University Press, 2019-05-10)
Plants mainly acquire N from the soil in the form of nitrate (NO3-) or ammonium (NH4+). Ammonium-based nutrition is gaining interest because it helps to avoid the environmental pollution associated with nitrate fertilization. ...
Public attitudes toward biodiversity‐friendly greenspace management in Europe
(Wiley, 2020)
Increasing urbanization worldwide calls for more sustainable urban development. Simultaneously, the global biodiversity crisis accentuates the need of fostering biodiversity within cities. Policies supporting urban nature ...
Isotopic labelling reveals the efficient adaptation of wheat root TCA cycle flux modes to match carbon demand under ammonium nutrition
(Nature Publishing Group, 2019-06-20)
Proper carbon (C) supply is essential for nitrogen (N) assimilation especially when plants are grown under ammonium (NH4+) nutrition. However, how C and N metabolic fluxes adapt to achieve so remains uncertain. In this ...
Relationship between salt use in fish farms and driftof macroinvertebrates in a freshwater stream
(Inter Research, 2020)
In Chile, salt (NaCl) use per salmon fish farm ranges between 20-30 t yr(-1) and is used to prevent and control fungal infections. An increase in salinity in freshwater can have adverse effects on freshwater biodiversity ...
Soil nitrogen dynamics during an oilseed rape (Brassica napus L.) growing cycle in a humid Mediterranean climate
(Nature Publishing, 2019-09-25)
Nitrogen budgets help explain the supply pattern of N from the soil to the crop. Through budgeting, an improvement of the N fertilization strategy can be achieved. The objective of the present study, which was carried out ...
