Global Climate Change Effects on Soil Microbial Biomass Stoichiometry in Alpine Ecosystems

Land, 2022
Alpine ecosystems are sensitive to global climate change-factors, which directly or indirectly affect the soil microbial biomass stoichiometry. In this paper, we have compared the soil microbial biomass stoichiometry ratios of alpine ecosystems using the

Global ecological predictors of the soil priming effect. [PDF]

, 2019
Identifying the global drivers of soil priming is essential to understanding C cycling in terrestrial ecosystems. We conducted a survey of soils across 86 globally-distributed locations, spanning a wide range of climates, biotic communities, and soil ...

Comparing models of microbial–substrate interactions and their response to warming [PDF]

Biogeosciences, 2016
Recent developments in modelling soil organic carbon decomposition include the explicit incorporation of enzyme and microbial dynamics. A characteristic of these models is a positive feedback between substrate and consumers, which is absent in ...

Different Response of Soil Microbial Carbon Use Efficiency in Compound of Feldspathic Sandstone and Sand

Agriculture, 2022
The stoichiometry of efficient soil microbial carbon use is a sensitive index for measuring changes in soil quality and plays a crucial role in research on ecological stoichiometry in the soil nutrient cycle.

Modeling the effect of soil meso- and macropores topology on the biodegradation of a soluble carbon substrate [PDF]

, 2015
Soil structure and interactions between biotic and abiotic processes are increasingly recognized as important for explaining the large uncertainties in the outputs of macroscopic SOM decomposition models.

Longer thaw seasons increase nitrogen availability for leaching during fall in tundra soils [PDF]

, 2016
Climate change has resulted in warmer soil temperatures, earlier spring thaw and later fall freeze-up, resulting in warmer soil temperatures and thawing of permafrost in tundra regions.

Fast-decaying tree litter reduces the temperature sensitivity of soil carbon decomposition by increasing microbial necromass carbon

Geoderma
Improvements in stocks and stability of forest soil organic carbon can be achieved through the management of tree species. Given the long lifespan of trees and their role as the keystone species in forested ecosystems, decisions regarding tree species ...

Nitrogen and phosphorus limitation of oceanic microbial growth during spring in the Gulf of Aqaba [PDF]

, 2009
Bioassay experiments were performed to identify how growth of key groups within the microbial community was simultaneously limited by nutrient (nitrogen and phosphorus) availability during spring in the Gulf of Aqaba's oceanic waters.

Straw return combined with water-saving irrigation increases microbial necromass accumulation by accelerating microbial growth-turnover in Mollisols of paddy fields

Geoderma
Soil microorganisms are key to the flow of carbon through soils. As the most carbon-rich soils, Mollisols are very sensitive to disturbance and more prone to be carbon sources than carbon sinks. To understand how the microbial physiology [i.e., microbial
