Data from: Allocation and functional traits of trees and saplings of Bornean tree species growing under contrasting soil nutrient availabilities
<p>The files hold the data of allocation and traits of adult trees ((i) the relationship between tree height and diameter at breast height, (ii) nutrient concentration in green leaves, senescent leaves, wood, and (iii) wood density) and saplings ((i) biomass allocation to leaves, stem, coarse roots, and fine roots, (ii) nutrient concentration in levees, senescent leaves, stem, and roots, and (iii) leaf mass per area) in Bornean tropical tree species growing under contrasting soil nutrient availabilities.</p> <p>Study site includes the Tawau Hills Park (4°27′N, 117°56′E, ca. 300 m asl), the Deramakot Forest Reserve (5°22′N, 117°25′E, ca. 250 m asl), and Nabawan (5°05′N, 116°29′E, ca. 500 m asl), Sabah, Malaysia. Vegetation of Tawau and Deramakot is a mixed dipterocarp forest, whereas that of Nabawan is a tropical heath forest. These sites considerably differ in soil characteristics. The forests in the Tawau Hills Park lie on the andesitic volcanic ash derived from the past eruptions ca. 27000 years ago by Mt. Magdalena, Mt. Lucia, and Mt. Maria. On the other hand, soils in the Deramakot Forest Reserve are derived from tertiary sedimentary rocks. Soils of Nabawan are classified as white sand podosol.</p>
Climate regulates the effect of land-use change on the diversity of soil microbial functional groups and soil multifunctionality
<p>Although studies have explored how soil microbial diversity and soil multifunctionality respond to land-use change at local scales, they have rarely been explored at larger scales and across different climatic and soil environmental conditions.</p> <p>By sampling 40 paired sites of land-use change from natural forests to agricultural lands (including croplands and orchards) along the middle and lower Yangtze River, combined with a global meta-analysis, we investigated the effects of land-use change and climate on the alpha and beta diversity of soil bacterial and fungal functional groups (FGs) and their associated soil multifunctionality at a regional scale.</p> <p>Our results showed that land-use change strongly changed the diversity of soil bacterial and fungal FGs and decreased multifunctionality, which was supported by our meta-analysis at a global scale. Direct effects of land-use change and climate and their interaction, together with changes in soil environmental variables, were the main determinants of the land-use change-induced changes in the diversity of soil bacterial or fungal FGs. The land-use change-induced decrease in multifunctionality was mainly associated with the direct effect of forest conversion, soil fertility, and diversity of fungal FGs. Furthermore, climate also regulated the effects of land-use change on multifunctionality by affecting soil fertility and fungal FGs diversity along the Yangtze River.</p> <p><em>Synthesis and applications</em>. Taken together, our findings highlight the important effects of land-use change, climate, and their interactions on microbial diversity and multifunctionality, and suggest that effective land-use management and climate change mitigation strategies should be adopted to protect biodiversity and ecosystem function in the Yangtze River Basin.</p>

Contrasting soil- and canopy-nurse effects on dependent species in metalliferous systems may be explained by dominant plant functional strategies
<p>Plant-plant interaction studies in metalliferous systems have focused either on the role of facilitation or on the negative effects of elemental allelopathy. However, no studies have investigated both of these effects in the same system, and their relationships with the functional strategy of the nurse species, although this is crucial for the ecological restoration of polluted sites.</p> <p>We assessed the effects of two dominant nurse species, with apparent contrasting strategies, on two target species on a slag heap in the Pyrenees (France). We quantified both long-term soil-engineering and short-term canopy effects on the growth of two target species. We also measured morphological traits and leaf metal concentration of the two nurse species and their effects on air moisture, temperature, and vapour pressure deficit.</p> <p>Nurse functional strategies, as inferred from morphological traits and leaf metal concentration seem to drive their long-term soil engineering effects on target species: Gypsophila repens, the relatively larger and more exploitative species with high leaf metal concentration, had negative long-term effects likely due to elemental allelopathy, whereas Minuartia verna, the relatively smaller and more conservative species with a lower amount of metals in leaves, had neutral long-term effects. Although Gypsophila repens had a slightly stronger positive effect on microclimate than Minuartia verna, this did not turn into higher short-term effects for the target species.</p> <p>Our study highlights the possible role of the nurse's functional strategies in driving the relative importance of long and short-term effects on target species in metalliferous systems. This knowledge is key to increasing our understanding of plant-plant interaction outcomes in metalliferous systems and our ability to restore polluted environments.</p>
Resprouting ability differs among plant functional groups along a soil acidification gradient in a meadow: A rhizosphere perspective
<p><span>Soil acidification as a global change factor can devastatingly affect plant growth and productivity. In frequently disturbed ecosystems, plant resprouting ability strongly determines biomass reconstruction and resilience after aboveground damage. However, how plant regrowth responds to soil acidification remains largely unknown, especially regarding the role of the rhizosphere in mediating this response. </span></p> <p><span>We manipulated a soil-acidification gradient via adding purified elemental sulfur powder at various rates (0-50 g S m<sup>−2</sup> year<sup>−1</sup>) in a frequently mown meadow. Shoot regrowth of functional groups were measured after clipping and supporting roles of rhizosphere versus bulk soils were disentangled using isotope labelling along the acidification gradient. </span></p> <p><span>Regrowth of grasses and sedges increased while forbs decreased along the acidification gradient. The results suggest that grasses were competitors capable of taking up nutrients from both rhizosphere and bulk soils, while sedges were acid-tolerators with lower sensitivity to decreased nitrogen-mineralization rates. Forbs, as typical ruderals, were vulnerable to N competition with microbes, particularly in the rhizosphere soil. Therefore, biomass regrowth of forbs was explained more by physicochemical and biological parameters from the rhizosphere than bulk soil</span></p> <p><span>Synthesis.</span><span> Divergent interplay between plant functional groups and rhizosphere soils was the prominent driver for biomass regrowth responding to soil acidification.</span></p>
Functional traits of soil nematodes define their response to nitrogen fertilization
<p>1. Nitrogen (N) fertilization and warming are two crucial global change factors affecting the soil nematode communities. The effects of N fertilization and warming, however, on nematode communities in soils are inconsistent across ecosystems and maybe be even opposite.</p> <p>2. One key reason is that the commonly used taxonomic diversity is less sensitive to environmental changes than the seldom-used trait-based indicators. To verify this, we performed an eight-year field experiment with four N fertilization levels with and without soil warming and collected an extensive dataset consisting of (i) six traits related to the nematode performance, i.e., body size, maximum body length, maximum body width, stylet length, esophagus length, and intestinal length; (ii) the taxonomic alpha (richness and abundance) and beta-diversity (Bray-Curtis dissimilarities) of the whole nematode community and each nematode functional group, (iii) soil food web resources (the total taxonomic richness and abundance of plant, bacterial and fungal communities), and (iv) soil properties (pH, total, ammonium and nitrate N, microbial N and C, total and available P and soil water content).</p> <p>3. We found that N fertilization altered plant diversity and soil nitrate levels, which in turn decreased taxonomic alpha diversity of two nematode functional groups (phytophagous nematodes and predators), but taxonomic diversity for the whole nematode community remained stable. The decreased taxonomic alpha diversity of phytophagous nematodes resulted in increased maximum body width, but decreased stylet length and esophageal length. Mild warming (~ 0.7 °C) had no effects on soil properties and soil food web resources, and the taxonomic diversity or nematode traits remained unchanged.</p> <p>4. Our results reveal that nematode functional traits show strong responses to N fertilization as individual nematode groups adapted quickly to changed soil properties and food web resources. Taxonomic diversity indices, however, were more stable under these changes showing that the functional composition of nematode communities may respond in the short-term despite little effects on species diversity. Thus, the trait-based indicators not only reveal how nematodes respond to N fertilization, but also how nematodes mediate the effects of N fertilization on ecosystem functioning (i.e., soil nutrient cycling).</p>
The data table of eleven invasive species in Hungary and Romania: Invasive species' cover, invasive species' traits, basic characteristics, trait composition, functional diversity indices and soil parameters of recipient plant communities
<p>We studied 11 widespread herbaceous invasive alien species of East-Central Europe and their 16 impact metrics (resident plant communities' ecological characteristics, trait composition, functional diversity, and soil parameters) by sampling invaded and similar, uninvaded sites (space-for-time substitution method). Our aim was to (1) investigate the detailed ecological impacts of invasive plants on native plant communities; (2) explore the type of cover-impact relationships across impact metrics and their consistency across species; (3) study whether the cover-impact relationship depends on functional traits of invasive species. We present the data table with the 11 invasive species: the status of the sites (invaded, uninvaded), the cover of invasive species at plot level, the invasive species traits (lifespan, height, SLA, seed mass, clonal spread, flowering duration), community characteristics (species richness and diversity, native vegetation cover and bare ground cover at plot level), trait composition of native plant communities (native vegetation height, CWM height, CWM SLA, CWM seed mass, CWM clonal spread), functional diversity (functional richness, functional evenness, functional divergence, functional distance, RaoQ) and soil properties (N, P, organic C, pH).</p>
Data for: Local conditions matter: Minimal and variable effects of soil disturbance on microbial communities and functions in European vineyards
<p>Soil tillage or herbicide applications are commonly us<span>ed in agriculture for weed control. These measures may also represent a disturbance for soil microbial communities and their functions. However, the generality of response patterns of microbial communities and functions to disturbance have rarely been studied at large geographical scales. We investigated how a soil disturbance gradient (low, intermediate, high), realized by either tillage or herbicide application, affects diversity and composition of soil bacterial and fungal communities as well as soil functions in vineyards across five European countries. Microbial alpha-diversity metrics responded to soil disturbance sporadically, but inconsistently across countries. Increasing soil disturbance changed soil microbial community composition at the European level. However, the effects of soil disturbance on the variation of microbial communities were smaller compared to the effects of location and soil covariates. Microbial respiration was consistently impaired by soil disturbance, while effects on decomposition of organic substrates were inconsistent and showed positive and negative responses depending on the respective country. </span><span>Therefore, we conclude that it is difficult to extrapolate results from one locality to others because microbial communities and environmental conditions vary strongly over larger geographical scales.</span><span> </span></p>
Soil protist functional composition shifts with atmospheric nitrogen deposition in subtropical forests
<p><span>1. </span><span>Soil protist plays a key role in ecological functions through predation and parasitism. However, little is known about how nitrogen (N) deposition and seasonal variations influence soil protist function in forest soils. </span></p> <p><span>2. </span><span>Here, we assessed firstly the impacts of N deposition (control, 50 kg N ha<sup>-1</sup> yr<sup>-1</sup>, 100 kg </span><span>N ha<sup>-1</sup> yr<sup>-1</sup></span><span>, and 150 kg </span><span>N ha<sup>-1</sup> yr<sup>-1</sup></span><span>) on the functional composition of the soil protist community in summer and winter, using amplicon sequencing of environmental DNA from a subtropical natural forest. </span></p> <p><span>3. </span><span>We found that soil protists were dominated by consumers (42.6–51.6%), followed by parasites (32.9–40.9%) and phototrophs (3.2–13.1%), implying a predominant role of consumers and potential top-down effects on the other trophic groups in subtropical forest soils. The functional composition of soil protists was greatly influenced by N deposition, but these responses were dependent on seasonal variations. The diversity of phototrophs was lower in summer than in winter. Instead, an opposite pattern was observed for consumers, resulting in a significantly higher protist diversity in summer than in winter, which indicates a greater sensitivity of soil protists to seasonal variations. Furthermore, low and high N deposition simplified the structural complexity of soil protist communities, suggesting a nonlinear response of the protist structural stability to N deposition.</span></p> <p><span>4. <em>Synthesis and applications.</em></span><span><em> </em>This study provides unprecedented evidence that season variation plays an important role in regulating responses of soil protist functional composition to N deposition, and highlights the nonlinear effects of rising N deposition levels on the soil food web. </span></p>
Data from: Effects of tree functional traits on soil respiration in tropical forest plantations
<p>The study covers four plantations stands of Acacia auriculiformis (A), Eucalyptus urophylla (E), Hopea odorata (H), and X. xylocarpa (X) through a sample plot (50 m x 50 m) in each stand from July 2015 until June 2016. Physical and chemical soil properties were collected at two depths (0-15 cm, 15-30 cm) at the beginning of the study (soil_properties_initial.csv). Additional samplings of topsoil pH, bulk density (BD, g cm-3), organic matter (OM, %), total carbon (TC, %), and nitrogen (TN, %) were conducted monthly (mo_yr) at five random locations (soil_properties_month.csv). Soil respiration (SR) was measured at the beginning of each month (mo_yr) at 12 locations (Point) within each species sample plot (Species) for ten hours (h_time) simultaneously with soil temperature (ST, C), air temperature (AT, C), relative humidity (RH), and soil moisture (SM, %) (soil_respiration.csv). The location of each soil respiration measurement point within the sample plots is provided as well (soil_respiration_location.csv). All trees within each sample plot were mapped (X, Y) and their stem basal area (BA_cm2) and height (H) were measured (stand_inventories.csv).</p>
Data from: Climatic water availability mainly drives context-dependency of tree functional diversity effects on soil organic carbon storage in European forests
<p>The interplay of forest stand and environmental factors shape soil organic C (SOC) storage in forest ecosystems but little is known about their relative impacts in different soil layers. Moreover, how environmental factors modulate the impact of stand factors, particularly species mixing, on SOC storage, is largely unexplored. In this study conducted in 21 forest triplets (two-species mixed stand and respective monocultures nearby) distributed in Europe, we tested the hypothesis that stand factors (functional identity and diversity) have stronger effects on topsoil (FF+0-10 cm) C storage than environmental factors (climatic water availability, clay+silt content, oxalate-extractable Al - Al<sub>ox</sub>) but that the opposite occurs in the subsoil (10-40 cm). We also tested the hypothesis that functional diversity improves SOC storage under high climatic water availability, clay+silt contents, Al<sub>ox</sub>. We characterized functional identity as the proportion of broadleaved species (beech and/or oak), and functional diversity as the product of broadleaved and conifer (pine) proportions. The results show that functional identity was the main driver of topsoil C storage while climatic water availability had the largest control on subsoil C storage. Contrary to expectations, functional diversity decreased topsoil C storage under increasing climatic water availability but the opposite was observed in the subsoil. Functional diversity effects on topsoil C increased with increasing clay+silt content, while its effects on subsoil C was negative at increasing Al<sub>ox</sub> content. This suggests that functional diversity effect on SOC storage along environmental gradients depends on the specific environmental factor and the soil depth under consideration.</p>

Fear of predators alters herbivore regulation of soil microbial community function
<p>Fear of predation can affect important ecosystem processes by altering the prey traits' expression that, in turn, regulates the quantity and quality of nutritional inputs to soil. Here, we aimed to assist in bridging a knowledge gap in this cascading chain of events by exploring how risk of spider predation may affect grasshopper prey performances, and the activity of various microbial extracellular enzymes in the soil. Using a mesocosms field‐experiment, we found that grasshoppers threatened by spider predation ate less, grew slower, and had a higher body carbon to nitrogen ratio. Herbivory increased activity of all microbial extracellular enzymes examined, likely due to higher availability of root exudates. Predation risk had no effect on C‐acquiring enzymes but decreased activity of P‐acquiring enzymes. We found contrasting results regarding the effect of predation on the activity of N‐acetyl‐glucosaminidase and leucine arylamidase N‐acquiring enzymes, suggesting that predation risk may alter the composition of N‐inputs to soil. Our work highlighted the importance of soil microbial enzymatic activity as a way to predict how changes in the aboveground food‐web dynamics may alter key ecosystem processes like nutritional‐cycling.</p>
Changes in nitrogen and phosphorus availability driven by secondary succession in temperate forests shape soil fungal communities and function
<p><span>Soil fungal community plays an important role in forest ecosystems, and forest secondary succession is a crucial driver of soil fungal community. However, the driving factors of fungal community and function during temperate forest succession and their potential impact on succession processes are poorly understood. In this study, we investigated the dynamics of the soil fungal community in three temperate forest secondary successional stages (shrublands, coniferous forests, and deciduous broadleaf forests) using high-throughput DNA sequencing coupled with functional prediction via the FUNGuild database. We found that fungal community richness, α-diversity, and evenness decreased significantly during the succession process. Soil available phosphorus and nitrate</span> <span>nitrogen decreased significantly after initial succession occurred, and redundancy analysis showed that both were significant predictors of soil fungal community structure. Among functional groups, fungal saprotrophs as well as pathotrophs represented by plant pathogens were significantly enriched in the early-successional stage, while fungal symbiotrophs represented by ectomycorrhiza were significantly increased in the late-successional stage. The abundance of both saprotroph and pathotroph fungal guilds was positively correlated with soil nitrate</span> <span>nitrogen and available phosphorus content. Ectomycorrhizal fungi were negatively correlated with nitrate</span> <span>nitrogen and available phosphorus content and positively correlated with ammonium</span> <span>nitrogen content.</span> <span>These results indicated that the dynamics of fungal community and function reflected the changes in nitrogen and phosphorus availability caused by the secondary succession of temperate forests. The fungal plant pathogen accumulated in the early-successional stage and ectomycorrhizal fungi accumulated in the late-successional stage may have a potential role in promoting forest succession. These findings contribute to a better understanding of the response of soil fungal communities to the secondary forest succession process and highlight the importance of fungal communities during temperate forest succession.</span></p>

Taxonomic and functional biogeographies of soil bacterial communities across the Tibet plateau are better explained by abiotic conditions than distance and plant community composition
<p><span>The processes governing soil bacteria biogeography are still not fully understood. It remains unknown how the importance of environmental filtering and dispersal differs between bacterial taxonomic and functional biogeography, and whether their importance is scale-dependent. We sampled soils across the Tibet plateau, with distances among plots ranging from 20 m to 1,550 km. Taxonomic composition of bacterial community was characterized by 16S amplicon sequencing and functional community composition by qPCR targeting 9 functional groups involved in N dynamics. Factors representing climate, soil, and plant community were measured to assess different facets of environmental dissimilarity. Both bacterial taxonomic and functional dissimilarities were more related to abiotic dissimilarity than biotic (vegetation) dissimilarity or distance. Taxonomic dissimilarity was mostly explained by differences in soil pH and mean annual temperature (MAT), while functional dissimilarity was linked to differences in soil N and P availabilities and N:P ratio. Soil pH and MAT remained the main determinants of taxonomic dissimilarity across spatial scales. In contrast, the explanatory variables of N-related functional dissimilarity varied across the scales, with soil moisture and organic matter having the highest role across short distances (<~330 km), and available P, N:P ratio and distance being important over long distances (>~660 km). Our results demonstrate how biodiversity dimension (taxonomic versus functional aspects) and spatial scale influence the factors driving soil bacterial biogeography.</span></p>
