Mineral weathering is linked to microbial priming in the critical zone

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Jan. 20, 2023

Abstract Decomposition of soil organic matter (SOM) can be stimulated by fresh input, a phenomenon known as the ‘priming effect’. Despite its global importance, relationship priming effect to mineral weathering and nutrient release remains unclear. Here we show close linkages between in critical zone primed decomposition SOM. Intensified rock-derived are generally coupled with SOM resulting from “triggered” microbial activity. Fluxes products decomposed via linearly correlated congruency. Weathering congruency influences formation organo-mineral associations, thereby modulating accessibility decomposers and, thus, effect. Our study links decomposition, which plays key role controlling C dynamics space time. These connections represent fundamental long-term lithogenic element cycling (= weathering) rapid turnover carbon nutrients priming) soil.

Photo-produced aromatic compounds stimulate microbial degradation of dissolved organic carbon in thermokarst lakes

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: June 21, 2023

Photochemical and biological degradation of dissolved organic carbon (DOC) their interactions jointly contribute to the dioxide released from surface waters in permafrost regions. However, mechanisms that govern coupled photochemical DOC are still poorly understood thermokarst lakes. Here, by combining Fourier transform ion cyclotron resonance mass spectrometry microbial high-throughput sequencing, we conducted a sunlight experiment using water samples collected 10 lakes along 1100-km transect. We demonstrate enhancement on biodegradation is not associated with low molecular weight aliphatics produced sunlight, but driven photo-produced aromatics. This aromatic compound-driven acceleration may be attributed potential high abilities microbes decompose complex compounds These findings highlight importance aromatics regulating effects permafrost-affected

Twenty Years of Progress, Challenges, and Opportunities in Measuring and Understanding Soil Respiration

Journal of Geophysical Research Biogeosciences, Journal Year: 2024, Volume and Issue: 129(2)

Published: Feb. 1, 2024

Abstract Soil respiration (Rs), the soil‐to‐atmosphere flux of CO 2 , is a dominant but uncertain part carbon cycle, even after decades study. This review focuses on progress in understanding Rs from laboratory incubations to global estimates. We survey key developments situ ecosystem‐scale observations and manipulations, synthesize meta‐analyses estimates, discuss most compelling challenges opportunities for future. Increasingly sophisticated lab experiments have yielded insights into interaction among heterotrophic respiration, substrate supply, enzymatic kinetics, extended incubation‐based analyses across space time. Observational manipulative field‐based used improved measurement approaches deepen our integrated effects environmental change disturbance Rs. Freely‐available observational databases enabled studies probing magnitude of, constraints on, flux. Key field include expanding measurements, experiments, under‐represented communities ecosystems; reconciling independent estimates fluxes trends; testing leveraging power machine learning process‐based models, both independently conjunction with each other; continuing field's tradition using novel explore diverse mechanisms ecosystems.

Experimental warming accelerates positive soil priming in a temperate grassland ecosystem

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Feb. 8, 2024

Abstract Unravelling biosphere feedback mechanisms is crucial for predicting the impacts of global warming. Soil priming, an effect fresh plant-derived carbon (C) on native soil organic (SOC) decomposition, a key mechanism that could release large amounts C into atmosphere. However, climate warming priming remain elusive. Here, we show experimental accelerates by 12.7% in temperate grassland. Warming alters bacterial communities, with 38% unique active phylotypes detected under The functional genes essential decomposition are also stimulated, which be linked to effects. We incorporate lab-derived information ecosystem model showing parameter uncertainty can reduced 32–37%. Model simulations from 2010 2016 indicate increase warming, 9.1% rise priming-induced CO 2 emissions. If our findings generalized other ecosystems over extended period time, play important role terrestrial cycle feedbacks and change.

Distinct Assembly Processes and Microbial Communities Constrain Soil Organic Carbon Formation

One Earth, Journal Year: 2020, Volume and Issue: 2(4), P. 349 - 360

Published: April 1, 2020

Soil stores more carbon (C) than all vegetation and the atmosphere combined. C stocks are broadly shaped by temperature, moisture, soil physical characteristics, vegetation, microbial-mediated metabolic processes. The efficiency with which microorganisms use regulates balance between storage in atmosphere. In this review, we discuss how microbial physiology community assembly processes determine growth rate and, turn, organic cycling through lens of ecology. We introduce a conceptual framework cataloging life history (i.e., rate, resource acquisition, stress tolerance) traits competition, facilitation, dispersal) that correspond different efficiencies. also compare dominant mycorrhizal fungal type affects efficiency. propose further development inclusion specific parameters microbial-explicit Earth system models needed for accurately predicting responses to global change.
