Increased arbuscular mycorrhizal tree dominance exacerbates soil microbial phosphorus limitation in a subtropical secondary forest: Evidence from ecoenzymatic stochiometry

Trees, Forests and People
Tree mycorrhizal association is a key determinant of soil microbial resource limitation in forests. However, how altered dominant tree mycorrhizal associations changes soil microbial resource limitation remains unclear in sub/tropical forests.

Contrasting responses of soil microbial biomass and extracellular enzyme activity along an elevation gradient on the eastern Qinghai-Tibetan Plateau [PDF]

, 2023
Soil microbial community composition and extracellular enzyme activity are two main drivers of biogeochemical cycling. Knowledge about their elevational patterns is of great importance for predicting ecosystem functioning in response to climate change ...

Exogenous P compounds differentially interacted with N availability to regulate enzymatic activities in a meadow steppe [PDF]

, 2019
Increased inputs of ecosystem nitrogen (N) and phosphorus (P) may affect the activity of soil enzymes that play essential roles in the metabolization of carbon (C), N and P for microbial growth. However, the associations between soil enzymatic activities

Effects of Litter Input on Soil Enzyme Activities and Their Stoichiometric Ratios in Sandy Soil

Agronomy
Litter serves as a crucial source of soil nutrients in sandy land ecosystems. Soil enzyme activities and their stoichiometric ratios act as essential “bridges” linking microbial metabolism with nutrient cycling, thereby reflecting the availability of ...

Plant attributes interact with fungal pathogens and nitrogen addition to drive soil enzymatic activities and their temporal variation [PDF]

, 2023
1. Nitrogen enrichment can alter soil communities and their functioning directly, via changes in nutrient availability and stoichiometry, or indirectly, by changing plant communities or the abundance of consumers.

Isotope signature and ecoenzymatic stoichiometry as key indicators of urban soil functionality

Journal of Soils and Sediments
Abstract Purpose This study aimed to assess the feasibility of the ecoenzymatic stoichiometry and isotope signature approaches as indicators of urban soil functionality, related to carbon and nutrient cycles. Methods In Pisa and Livorno (Italy), study sites with three degrees of ...

Linking root biomass and traits with soil C and nutrients stocks and microbial activity down to 100 cm depth in a young Mediterranean agroforestry system [PDF]

, 2022
In the subsoils, roots represent a major source of organic matter. Moreover, the C inputs from rhizodeposition, root turnover (mostly perennial species) and root mortality at harvest (annual crops) have a long residence time in soil due to slow ...

Shifts in microbial community structure and function in stream sediments during experimentally simulated riparian succession [PDF]

, 2017
Successional changes of terrestrial vegetation can profoundly influence stream ecosystem structure and function. We hypothesized that microbial enzyme production and community structure in stream beds depend on terrestrial litter inputs that reflect ...
