Aim The priming effect (PE) refers to changes in the decomposition of native soil organic carbon induced by exogenous carbon inputs. Specifically, an increase in native soil

Soils are the largest repository of organic carbon in the terrestrial biosphere. Nevertheless, soil microbial ecology relatively little is known about the factors controlling the efficiency with which

Microbial contributions to climate change through carbon cycle feedbacks

Conceptual framework of plant-microbial-soil feedbacks within ECM and ...

2008 ; Karhu et al., 2014 ). To determine the mechanisms underlying the decline in heterotrophic soil microbial respiration with warming in the longer term, focus has been predominantly on the

However, unlike plant communities, little is known about how the diversity and biomass of soil microbial communities are interlinked across globally distributed biomes, and

Aims The interactions between aboveground and belowground biota are crucial for determining plant community composition and the response of ecosystem stability to climate Integrating microbial residues into current climate-C models is expected to enable the models to more accurately evaluate soil C responses to climate regimes in semiarid Aims Understanding the long-term effects of elevated atmospheric CO2 (eCO2) and warming on soil organic carbon (SOC), along with the microbial mechanisms involved, is

The feedback response of soil microbial communities to climate warming is one of the major uncertainties in projecting future climate

Explicit inclusion of coexistence history and the local adaptation of plants and soil microbes at local and regional scales will enable more realistic predictions about the Our findings emphasize the consistent compensatory thermal adaptation of microbial respiration in forest soils and the critical link between microbial communities and thermal adaptation, with

  • Microbial mediation of carbon-cycle feedbacks to climate warming

Background and aims The increasing occurrence of extreme drought events under climate change alters the composition and functioning of plant communities worldwide. Drought

Environmental stress destabilizes microbial networks

Understanding the alterations in soil microbial communities in response to climate warming and their controls over soil carbon (C) processes is crucial for projecting permafrost C-climate Aims Nitrogen (N) and phosphorus (P) deposition, along with climate warming, are key environmental factors driving soil organic carbon (SOC) dynamics in forests. The study

Microbial necromass has been proved to be an important source of stable soil organic carbon (SOC), responding sensitively to global climate warming. Nevertheless, how

Soil microbes play critical roles in regulating terrestrial carbon (C) cycle and its feedback that experimental warming accelerates soil to climate change. However, it is still unclear how the soil microbial community and

Although the drivers of α-diversity are well-studied for animal and plant communities, they are often overlooked for soil microbes, particularly in natural systems. Owing to advances in sequencing technologies, it is currently possible to determine the taxonomic composition of soil microbial communities and to determine how climate change A study based on a long-term manipulation experiment in a grassland ecosystem describes the microbial mechanisms controlling feedbacks to carbon and nutrient cycling under

Microbes are key biodiversity components of all ecosystems and control refers to vital ecosystem functions. Although we have just begun to unravel the

Thus, the feedback loop between inorganic nitrogen dynamics and microbial communities (steps 2–4 in Fig. 1) could be a key mechanism of We show that climate drivers such as warming, drought and warming-induced vegetation shift strongly affect microbial diversity, community composition, trophic structure

To understand whether and how climate warming affects STR and/or PTR in soil microbial communities, we examined the temporal scaling of soil microbial communities in a Quantifying the rate of thermal adaptation of soil microbial respiration is essential in determining potential for carbon cycle feedbacks under a warming climate.

Identifying soil microbial feedbacks to increasing temperatures and moisture alterations is critical for predicting how terrestrial ecosystems will However, the impacts of climate warming on soil priming remain elusive. Here, we show that experimental warming accelerates soil priming by 12.7% in a temperate grassland.

Although it is known that increasing temperature can stimulate microbial degradation of soil organic carbon and increase the atmospheric concentration of CO 2 (10 – Temperature controls microbial rates of decomposition, and thus warming can stimulate C loss, creating positive feedback to climate change.

Summary Plant–soil feedback (PSF) occurs when plants alter soil properties that influence the performance of seedlings, with consequent effects on plant populations and Nie, M., Pendall, E., Bell, C., Gasch, C. K., Raut, S., Tamang, S., & Wallenstein, M. D. (2012). Positive climate feedbacks of soil microbial communities in a semi Dilution of soil microbial effects is a mechanism of positive plant diversity-productivity relationships. Specialist pathogens and mutualists accumulate in the soil of

Soil microbial respiration is an important source of uncertainty in projecting future climate and carbon (C) cycle feedbacks. However, its feedbacks to climate warming and Environmental stress is increasing worldwide, yet we lack a clear picture of how stress disrupts the stability of microbial communities and the ecosystem services they provide.

Abstract Plant-soil feedbacks (PSFs) are interactions among plants, soil organisms, and abiotic soil conditions that influence plant performance, plant Using a large global dataset of plant–soil feedback (PSF) experiments, we did not find a more negative PSF at lower latitudes. Rather, PSF was consistently more positive at A better understanding of soil microbial ecology is critical to gaining an understanding of terrestrial carbon (C) cycle–climate change feedbacks.
