Soil microbial communities play a crucial role in the functioning of terrestrial ecosystems. Rapid changes in climate and land-use will likely cause major changes in belowground biodiversity with unknown consequences on ecosystem functioning. The functional traits, taxonomic and functional diversities of soil microorganisms are known to vary in relation to soil type and climate, but few studies have

Resistance and resilience of co-occurring nitrifying microbial guilds to drying-rewetting stress in soil Soil Biol. Biochem. (IF 9.8) Pub Date : 2025-05-08 Laura J. Müller, Mara Alicke, Sana Romdhane, Grace Pold, Christopher M. Jones, Aurélien Saghaï, Sara Hallin
Nitrification, the oxidation of ammonia via nitrite to nitrate, contributes to nitrogen losses in agricultural soils. When nitrification is a two-step process, it depends on the successful metabolic interaction between ammonia oxidising archaea (AOA) and bacteria (AOB), and nitrite oxidising bacteria primarily within Nitrobacter (NIB) and Nitrospira (NIS). However, consequences of dry spells caused

Large underestimations of warming-induced soil carbon emissions from oversimplistic Q10 indicator Soil Biol. Biochem. (IF 9.8) Pub Date : 2025-04-28 Gabriel Y.K. Moinet, Karen Morán-Rivera, Antoine Moinet, Alexandre M.J.-C. Wadoux
The sensitivity of soil microbial respiration to climate warming is a major source of uncertainty in predicting soil carbon (C) emissions to the atmosphere and their feedback to climate change. One key issue is the persistent misuse of Q10, the factor by which respiration rate is multiplied for a 10 °C increase in temperature, as an indicator of the temperature sensitivity. Despite ample empirical

Enhanced understanding of soil methane processes through modeling microbial kinetics and taxonomy Soil Biol. Biochem. (IF 9.8) Pub Date : 2025-04-25 Shuhao Zhou, Gangsheng Wang, Wenjuan Huang, Kefeng Wang, Liping Zhang, Zehao Lv, Yajing Han, Shanshan Qi, Wei Zhang, Daifeng Xiang, Steven J. Hall
Soil methane (CH4) emissions significantly impact climate change. However, microbial controls of CH4 in global carbon cycle gain less attention than CO2, hindering the understanding of CH4 processes. Here, stemming from a baseline model (MENDmm1) with one microbial group, we developed a microbial-explicit CH4 model by representing six microbial groups following Michaelis-Menten kinetics (MENDmm6).

Ecological traits of high-affinity hydrogen-oxidizing soil bacteria involved in the hydrogen cycle Soil Biol. Biochem. (IF 9.8) Pub Date : 2025-04-21 Lijun Hou, Joann K. Whalen, Philippe Constant
Every year, soil microbial-mediated hydrogen (H2) oxidation removes about 80 % of the global atmospheric H2, an indirect greenhouse gas. Soil-dwelling high-affinity H2 oxidizing bacteria use this trace gas as an energy source to persist when other substrates are limited or to meet their maintenance energy requirements during dormancy. However, there is limited knowledge of the distribution, composition

Jeewani, Robert W. Brown, Chris D. Evans, Jack Cook, Benjamin P. Roberts, Mariecia D. Fraser, David R. Chadwick, Davey L. Jones
Peat soils store significant amounts of carbon (C) globally, and increased C sequestration into peatlands could play a role in offsetting anthropogenic greenhouse gas (GHG) emissions. As such, there is a need to find and assess optimal greenhouse gas removal (GGR) interventions to minimise GHG losses, protect current C stocks, and promote further C sequestration. This mesocosm study assessed the additional
