Human-induced nitrogen–phosphorus imbalances alter natural and managed ecosystems across the globe

TL;DR: In this article, the authors examined which strategies would be adopted by plants for alleviating P deficiency caused by N enrichment from the perspective of aboveground conservation and belowground uptake, and found that N addition significantly reduced soil available P concentration and enhanced leaf N:P ratio, indicating the increasing degree of P deficiency under N addition.

TL;DR: In this article, the authors applied an empirical modelling approach for gross primary productivity (GPP) estimation from hyperspectral reflectance of Mediterranean grasslands undergoing different fertilization treatments.

TL;DR: The findings demonstrate that it is generally possible to use herbarium specimens for metagenomic analyses, but that the results should be treated with caution, as some of the identified species may be her barium contaminants rather than representing the natural metagenomics community of the host plant.

TL;DR: Investigating the effect of plant invasion, subsequent removal and replanting with a native species on C, N and P stoichiometry of the plant–soil system in the tidal wetlands of the Minjiang River shows that a conservative strategy and a high N-use efficiency and internal plant control of the N in the ecosystem underlie the invasive success of Spartina in this N-limited wetland.

TL;DR: It is shown that tremendous progress could be made by halting agricultural expansion, closing ‘yield gaps’ on underperforming lands, increasing cropping efficiency, shifting diets and reducing waste, which could double food production while greatly reducing the environmental impacts of agriculture.

TL;DR: In this paper, the authors compared the natural and anthropogenic controls on the conversion of unreactive N2 to more reactive forms of nitrogen (Nr) and found that human activities increasingly dominate the N budget at the global and at most regional scales, and the terrestrial and open ocean N budgets are essentially dis-connected.

TL;DR: Thank you very much for reading ecological stoichiometry the biology of elements from molecules to the biosphere, and maybe you have knowledge that, people have look hundreds of times for their chosen readings, but end up in infectious downloads.

TL;DR: A large-scale meta-analysis of experimental enrichments shows that P limitation is equally strong across these major habitats and that N and P limitation are equivalent within both terrestrial and freshwater systems.
