TL;DR: A global-scale meta-analysis of the seven-most widely measured soil enzyme activities is conducted, indicating that the enzymatic potential for hydrolyzing the labile components of soil organic matter is tied to substrate availability, soil pH and the stoichiometry of microbial nutrient demand.

TL;DR: In this paper, the role of microbial processes in aridland ecosystem dynamics has been investigated, including efficient decomposition of recalcitrant C compounds, N-transformations such as nitrification, and nutrient storage and translocation of C and N between plants and biotic soil crusts.

TL;DR: The common observation of connections between ecosystem process drivers and microbial diversity suggests that microbial taxonomic turnover could mediate ecosystem-scale responses to changing environmental conditions, including both microbial habitat distribution and physicochemical factors.

TL;DR: In this paper, it was shown that southwestern urban streams are neither N-limited nor retentive of N because of N limitation, high productivity, and high channel complexity (in particular, extensive transient storage associated with the hyporheic zone), and that human modifications may restore N retention functions if channel complexity and heterogeneity are as important to N retention efficiency as be...

TL;DR: Between-site variation in both soil properties and EEA exceeded any treatment response, and a large portion of EEA variability was strongly related to soil pH, making potential breakdown rates of SOM resistant to N enrichment.
