Data from: Climate, soil resources and microbial activity shape the distributions of mountain plants based on their functional traits
<p>While soil ecosystems undergo important modi cations due to global change, the e ect of soil properties on plant distributions is still poorly understood. Plant growth is not only controlled by soil physico-chemistry but also by microbial activities through the decomposition of organic matter and the recycling of nutrients essential for plants. A growing body of evidence also suggests that plant functional traits modulate spe- cies' response to environmental gradients. However, no study has yet contrasted the importance of soil physico-chemistry, microbial activities and climate on plant species distributions, while accounting for how plant functional traits can in uence species- speci c responses.</p> <p>Using hierarchical e ects in a multi-species distribution model, we investigate how<br> four functional traits related to resource acquisition (plant height, leaf carbon to nitro-<br> gen ratio, leaf dry matter content and speci c leaf area) modulate the response of<br> 44 plant species to climatic variables, soil physico-chemical properties and microbial 100 decomposition activity (i.e. exoenzymatic activities) in the French Alps.</p> <p>Our hierarchical trait-based model allowed to predict well 41 species according to the TSS statistic. In addition to climate, the combination of soil C/N, as a measure of organic matter quality, and exoenzymatic activity, as a measure of microbial decom- position activity, strongly improved predictions of plant distributions. Plant traits played an important role. In particular, species with conservative traits performed bet- ter under limiting nutrient conditions but were outcompeted by exploitative plants in more favorable environments.</p> <p>We demonstrate tight associations between microbial decomposition activity, plant functional traits associated to di erent resource acquisition strategies and plant dis- tributions. is highlights the importance of plant–soil linkages for mountain plant distributions. ese results are crucial for biodiversity modelling in a world where both climatic and soil systems are undergoing profound and rapid transformations.</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: Grazing and nitrogen addition restructure the spatial heterogeneity of soil microbial community structure and enzymatic activities
<p>1. In grassland ecosystems, large herbivorous animal grazing activity and increasing nitrogen deposition strongly alters microbial community structure and function. Understanding the effects of grazing and nitrogen addition on the spatial heterogeneity in soil microbial community structure, enzymatic activities and the underlying mechanisms are crucial for making better predictions of soil organic matter dynamics and nutrient cycling. </p> <p>2. We examined the spatial heterogeneity of soil microbial community structure and enzymatic activity associated with changes in soil microclimate, soil characteristics, plant biomass and soil nutrient responses to grazing and nitrogen addition using a manipulative experiment with control (CK), grazing (G), nitrogen addition (N) and grazing plus nitrogen addition (NG) treatments in a <i>Leymus chinensis </i>meadow steppe, in northeastern China. </p> <p>3. The results demonstrated that soil microbial community structure and enzymatic activities showed a high level of spatial dependence [C/(C + C0)≥0.9] in the CK plot. G, N and NG treatments not only reduced the spatial variability ofsoil microbial community structure and enzymatic activities, but also reshaped the spatial links between enzymes activities and microbial community structure. Litter biomass, soil temperature and soil nutrients (soil dissolved inorganic nitrogen or soil dissolved organic carbon) explained 21-27% of the spatial variability of soil microbial community structure in the CK treatment and pH was the strongest driver for the spatial variability of soil enzymatic activities. Meanwhile, the homogenization in soil water content induced by the N addition treatment was a determinant of the reduction in spatial heterogeneity of the microbial community structure. The combination of soil physicochemical properties (bulk density, soil pH and soil dissolved inorganic nitrogen), soil temperature and root biomass explained 32-43% of the spatial variability of the microbial community structure in the G treatment, and N and G treatments had additive effects on the spatial heterogeneity of total PLFAs by homogenizing root biomass. Plant biomass and microbial community structure were the major drivers for the spatial heterogeneity of enzymatic activities under G, N and NG. In NG, the change in spatial variability of enzymatic activities was dominated by N addition. Regardless of grazing, N addition facilitated the spatial correlation between microbial community structure and enzyme activities. </p> <p>4. Overall, our results revealed the drivers of soil microbial community structure and enzymatic activities spatial pattern shift due to grazing and N addition, highlighting the role that spatial variability in soil microbial community structure and enzymatic activities has on the <i>L. chinensis</i> meadow steppe.</p>
