The role of soil microbes in the global carbon cycle: tracking the below-ground microbial processing of plant-derived carbon for manipulating carbon dynamics in agricultural systems. [PDF]

, 2014
It is well known that atmospheric concentrations of carbon dioxide (CO2) (and other greenhouse gases) have increased markedly as a result of human activity since the industrial revolution. It is perhaps less appreciated that natural and managed soils are

Microbial necromass carbon and nitrogen persistence are decoupled in agricultural grassland soils

Communications Earth & Environment, 2022
Different mineralization rates between plant litter and microbial necromass do not necessarily imply differences in carbon persistence, and necromass carbon is less persistent than nitrogen, according to inoculation experiments with grassland soils under

Microbial dynamics in a High Arctic glacier forefield: A combined field, laboratory, and modelling approach [PDF]

, 2016
Modelling the development of soils in glacier forefields is necessary in order to assess how microbial and geochemical processes interact and shape soil development in response to glacier retreat.

Bacterial Necromass Is Rapidly Metabolized by Heterotrophic Bacteria and Supports Multiple Trophic Levels of the Groundwater Microbiome

Microbiology Spectrum, 2022
Pristine groundwater is a highly stable environment with microbes adapted to dark, oligotrophic conditions. Input events like heavy rainfalls can introduce the excess particulate organic matter, including surface-derived microorganisms, thereby ...

Caco3 precipitation in multilayered cyanobacterial mats: Clues to explain the alternation of micrite and sparite layers in calcareous stromatolites [PDF]

, 2015
© 2015 by the authors; licensee MDPI, Basel, Switzerland. Marine cyanobacterial mats were cultured on coastal sediments (Nivå Bay, Øresund, Denmark) for over three years in a closed system. Carbonate particles formed in two different modes in the mat: (i)

Effect of soil waterlogging on below-ground biomass allometric relations in Norway spruce [PDF]

, 2010
An increasing importance is assigned to the estimation and verification of carbon stocks in forests. Forestry practice has several long-established and reliable methods for the assessment of aboveground biomass; however we still miss accurate predictors ...

Microbial Necromass, Lignin, and Glycoproteins for Determining and Optimizing Blue Carbon Formation

Environmental Science & Technology, 2023
Coastal wetlands contribute to the mitigation of climate change through the sequestration of "blue carbon". Microbial necromass, lignin, and glycoproteins (i.e., glomalin-related soil proteins (GRSP)), as important components of soil organic carbon (SOC), are sensitive to environmental change.

Mineralogy dictates the initial mechanism of microbial necromass association

Geochimica et Cosmochimica Acta, 2019
Abstract Soil organic matter (SOM) improves soil fertility and mitigates disturbance related to climate and land use change. Microbial necromass (the accumulated cellular residues of microorganisms) comprises the majority of soil C, yet the formation and persistence of necromass in relation to mineralogy is poorly understood.

Differences in mycelial turnover and persistence of wood-decay fungi at the microscale. [PDF]

New Phytol
Summary How long do fungal hyphae persist in the environment? And how does this differ between groups and species of fungi? Despite growing knowledge of fungal contributions to decomposition and soil carbon cycles, surprisingly little is known about the turnover of mycelia: What happens to fungal hyphae over time? And how this impacts different fungi's

Inorganic nitrogen availability alters Eucalyptus grandis receptivity to the ectomycorrhizal fungus Pisolithus albus but not symbiotic nitrogen transfer. [PDF]

, 2020
Forest trees are able to thrive in nutrient-poor soils in part because they obtain growth-limiting nutrients, especially nitrogen (N), through mutualistic symbiosis with ectomycorrhizal (ECM) fungi.
