N:PPurpose With increasing urban area and population, global cities are playing a more important role in the alteration of the global biogeochemical cycles. The aims of this study are to understand the concentrations and stoichiometric relations of biogenic elements (C, N, and P) in urban soils...
Thus, it should be possible to incorporate models used to design and implement urban engineering projects into urban biogeochemical models to predict the effects of the built environment on nutrient and energy cycles. Eventually, these hybrid engineering-ecology models could be linked to the energy ...
soils, and the connectivity to water channels. Most material mobilized by overland orsheet erosionis deposited nearby in a matter of seconds or minutes during a storm, often resulting in a rapid input of C and N into the deposited area and potentially altering thenutrientcycles in both...
The main source of energy that drives the dynamics of Earth’s outer spheres, including its climate, is unquestionably the Sun.
), the quality of DNA extraction was examined by using 1% agarose gel electrophoresis, and DNA concentration and purity were determined by using a NanoDrop2000. The V3-V4 variable region of 16 S rRNA was selected for PCR amplification, predenatured at 95 °C for 3 min, 27 cycles (...
Changes in nutrient loads, whether anthropogenic or not, can interfere with the preexisting biogeochemical cycles within wetlands and significantly affect the gas emission quality and soil nutrient stocks. Anomalous concentrations of N or S can have inhibitory effects on the C cycle (Kaushal et al....
This study provides the longest trend analysis of Nitrogen (N) and phosphorus (P) surplus in France from 1920 to 2020, modeled with the CaSSiS model at both national and departmental levels. At the national scale, the century long average annual N surplus is about 37 ± 13 kg N per ha ...
However, this function has been lost in many ecosystems due to catchment eutrophication by agricultural and urban development. We conclude that the estuaries of the Falkland Islands provide a valuable pre-disturbance analogue for natural biogeochemical functioning in temperate estuaries receiving high ...
