Data for: Exogenous carbon turnover within the soil food web strengthens soil carbon sequestration through microbial necromass accumulation
<p>Exogenous carbon turnover within soil food web is important in determining the trade-offs between soil organic carbon (SOC) storage and carbon emission. However, it remains largely unknown how soil food web influences carbon sequestration through mediating the dual roles of microbes as decomposers and contributors, hindering our ability to develop policies for soil carbon management. Here, we conducted a 13C-labeled straw experiment to demonstrate how soil food web regulated the residing microbes to influence the soil carbon transformation and stabilization process after 11 years no-tillage. Our work demonstrated that soil fauna, as a "temporary storage container", indirectly influenced the SOC transformation processes and mediated the SOC sequestration through feeding on soil microbes. Soil biota communities acted as both drivers of and contributors to SOC cycling, with 32.0% of exogenous carbon being stabilizing in the form of microbial necromass as "new" carbon. Additionally, the proportion of mineral-associated organic carbon and particulate organic carbon showed that the "renewal effect" driven by the soil food web promoted the SOC to be more stable. Our study clearly illustrated that soil food web regulated the turnover of exogenous carbon inputs and mediated soil carbon sequestration through microbial necromass accumulation.</p>

Dataset for the project "The role of expansive and invasive plant species in shaping the activity of microbial communities and carbon sequestration in the soil of post-mining spoil heaps."
<p>Description of the project: Research on carbon sequestration in all types of ecosystems, including human-transformed oligotrophic ecosystems, has become more important today from a climate change perspective, as it can help mitigate its effects. Increasing the potential for C sequestration on brownfield sites can be achieved by improving biological processes and developing soil organic matter reservoirs. This may be particularly relevant for the functioning of oligotrophic ecosystems such as waste coal mine spoil heaps. In studies conducted to date on soil carbon dynamics, it has been found that carbon storage capacity is related to vegetation type, among other factors. This is mainly due to the fact that different plant species affect the physical and chemical properties of the soil, the chemical composition of the litter, detritus supply and rooting depth differently. Furthermore, plant species have been shown to influence the composition and biomass of soil microbial communities, and these microorganisms are responsible for the decomposition of organic compounds in the soil. There is little knowledge of soil microbial communities and their activities in the different plant communities of post-mining spoil heaps, especially with regard to the effects of specific microbial communities on soil carbon sequestration. The aim of the project was to compare the influence of a native expansive grass species (<em>Calamagrostis epigejos</em> (L.) ROTH) and an alien invasive species (<em>Solidago gigantea</em> AITION) on the activity and structure of soil microorganisms and carbon sequestration on post-mining spoil heaps spontaneously colonised by vegetation and subjected to reclamation. The study was carried out on a model post-mining heap, part of which has been reclaimed with overburdened soil, while the remaining part has not undergone any reclamation and is subject to spontaneous succession processes. An analysis of total organic carbon (TOC) in soil substrate samples was carried out to determine the effect of the plant species studied on carbon sequestration. TOC consists of organic compounds mainly derived from root exudates, microbial biomass and decomposition of plant litter and SOM by microorganisms. Therefore, the structure of soil microbial assemblages was also investigated by means of phospholipid fatty acid profiles and the activity of these microorganisms, by means of soil enzyme analysis and functional diversity of microorganisms using BIOLOG<sup>®</sup> Ecoplates. In addition, the in situ level of CO<sub>2</sub> release from the soil was also determined.</p>
Data from: Top-down control of carbon sequestration: grazing affects microbial structure and function in salt marsh soils
Tidal wetlands have been increasingly recognized as long-term carbon sinks in recent years. Work on carbon sequestration and decomposition processes in tidal wetlands focused so far mainly on effects of global-change factors such as sea-level rise and increasing temperatures. However, little is known about effects of land use, such as livestock grazing, on organic matter decomposition and ultimately carbon sequestration. The present work aims at understanding the mechanisms by which large herbivores can affect organic matter decomposition in tidal wetlands. This was achieved by studying both direct animal-microbe interactions and indirect animal-plant-microbe interactions in grazed and ungrazed areas of two long-term experimental field sites at the German North Sea coast. We assessed bacterial and fungal gene abundance using quantitative PCR, as well as the activity of microbial exo-enzymes by conducting fluorometric assays. We demonstrate that grazing can have a profound impact on the microbial community structure of tidal wetland soils, by consistently increasing the fungi-to-bacteria ratio by 38-42%, and therefore potentially exerts important control over carbon turnover and sequestration. The observed shift in the microbial community was primarily driven by organic matter source, with higher contributions of recalcitrant autochthonous (terrestrial) vs. easily degradable allochthonous (marine) sources in grazed areas favoring relative fungal abundance. We propose a novel and indirect form of animal-plant-microbe interaction: top-down control of aboveground vegetation structure determines the capacity of allochthonous organic matter trapping during flooding and thus the structure of the microbial community. Furthermore, our data provide the first evidence that grazing slows down microbial exo-enzyme activity and thus decomposition through changes in soil redox chemistry. Activities of enzymes involved in C cycling were reduced by 28-40%, while activities of enzymes involved in N cycling were not consistently affected by grazing. It remains unclear if this is a trampling-driven direct grazing effect, as hypothesized in earlier studies, or if the effect on redox chemistry is plant mediated and thus indirect. This study improves our process-level understanding of how grazing can affect the microbial ecology and biogeochemistry of semi-terrestrial ecosystems that may help explain and predict differences in C turnover and sequestration rates between grazed and ungrazed systems.

Nutrient availability and stoichiometry mediate microbial effects on soil carbon sequestration in tropical forests
<p>A one-year <em>in situ</em> soil incubation experiment using mesh bags (mesh size of 38 µm, allowing colonization of bacteria and penetration of fungal hyphal but precluding root penetration) with fertile sugarcane soil and infertile sand along an elevational gradient characterized by varied climatic and biotic conditions in a tropical forest. Biomarkers, including phospholipid fatty acids, carbon-nitrogen-phosphorus acquiring hydrolases, glomalin-related proteins and amino sugars were measured to characterize the production and accumulation of microbial living biomass, exo-enzymes, extracellular glycoprotein and microbial necromass, and to elucidate their contributions to SOC sequestration.</p>
