TL;DR: It is found that extracellular enzyme responses of a forest-floor microbial community to chronically applied aqueous NH4NO3 can explain both increased and decreased litter decomposition rates caused by added N.

TL;DR: In this article, the authors proposed a framework to integrate biogeochemical processes into designing, implementing, and evaluating the net effectiveness of green infrastructure, and provide examples for GHG mitigation, stormwater runoff mitigation, and improvements in air quality and health.

TL;DR: The results show that relatively small shifts intheactivity of one or two critical enzymes can significantly alter decompositionrates, and across litter types, N amendment reducedarent enzymatic efficiencies and shifted EEA away from N acquisition and toward P acquisition, and away from polyphenol oxidation and toward polysaccharide hydrolysis.

TL;DR: In this paper, the effect of urban development on the functioning of forest ecosystems during the past decade was studied, where red oak stands located on similar soil along an urban-rural gradient running from New York City to rural Litchfield County, Connecticut.

TL;DR: Soil enzyme activities and microbial biomass were measured in a grassland ecosystem with a wide range of heavy metal concentrations ranging from 7.2 to 48.1 mmol kg−1 (As, Cd, Cr, Cu, Ni, Pb and Zn) in portions of the U.S. Army's Aberdeen Proving Ground, Maryland.
