Nitrogen Fertilizer Suppresses Mineralization of Soil Organic Matter in Maize Agroecosystems
Frontiers in Ecology and Evolution, 2019 The possibility that N fertilizer increases soil organic matter (SOM) mineralization and, as a result, reduces SOM stocks has led to a great debate about the long-term sustainability of maize-based agroecosystems as well as the best method to estimate ...

The Effects of Logging, Fire and Blowdown on Colorado Subalpine Forest Soil [PDF]
, 2009 Disturbance ecology is a growing field within ecology, and while studies of individual and discrete disturbances are increasing in number, there is a paucity of studies on the ecological effects of disturbance interactions.

La biomasa microbiana y la mineralización de N en plantaciones mixtas de frondosas y especies fijadoras de nitrógeno [PDF]
, 2011 Mixed stands with nitrogen fixing secondary species can improve the vigour and the stand environment of the targeted species. The aim of this study was to better understand the effect of the consociation of a N-fixing species (black locust) with a ...

Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes
Advanced Functional Materials, EarlyView.Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

Bioinspired Stabilization of Fluorescent Au@SiO2 Tracers for Multimodal Biological Imaging
Advanced Functional Materials, EarlyView.This study demonstrates a bioinspired stabilization strategy for fluorescent gold‐silica nanoparticles. Inspired by natural biosilica maturation, high‐temperature calcination transforms the silica shells, preventing dissolution in cell culture media and intracellular environments.

Biological and microbial activity in biological soil crusts from the Tabernas desert, a sub-arid zone in SE Spain. [PDF]
, 2012 The ecology and functional role of biological soil crusts (BSCs) in arid and semi-arid zones have been extremely well studied. However, little is known about the biochemical properties related to the number and activity of the microbiota that form the ...

THE EFFECT OF SOME MANGANESE SALTS ON AMMONIFICATION AND NITRIFICATION
Soil Science, 1916 Manganese occurs in practically all soils, but the quantities present are exceedingly variable. Twenty-six typical soils analyzed by Robinson showed the presence of manganese in amounts varying from 0.01 to 0.51 per cent of MnO. Other studies have shown the occurrence of very large amounts in certain soils, but the average of 0.071 per cent MnO given ...

Advanced Functional Materials, EarlyView.Synthesis and characterization of light‐responsive donor–acceptor Stenhouse adducts (DASA)‐coated chlorhexidine‐loaded silica nanoparticles. Such a controllable drug‐delivery system enables the release of the antimicrobial drug on demand and in consecutive cycles, thereby maintaining the concentration within the therapeutic window.
