Data for a global meta-analysis of passive experimental warming effects on plant traits and community properties
This database contains the data used in a global meta-analysis of warming effects on plants. L0 data are available upon request; they include the raw data from 126 warming experiments. The L1 data are the result of merged L0 data and are cleaned for typos and are standardized names. L1 data contain plant trait and community property measurements in both warmed and ambient conditions. L2 data contain the effect sizes of warming for each study. These data came from 126 warming experiments across the globe.

Data from: Above-belowground linkages of functionally dissimilar plant communities and soil properties in a grassland experiment
<p>Changes in plant community composition can have long-lasting consequences for ecosystem functioning. However, how the duration of plant growth of functionally distinct grassland plant communities influences abiotic and biotic soil properties and thus ecosystem functions is poorly known. In a field experiment, we established identical experimental subplots in two successive years comprising of fast- or slow-growing grass and forb community mixtures with different forb:grass ratios. After one and two years of plant growth, we measured above- and belowground biomass, soil abiotic characteristics (pH, organic matter, soil nutrients), soil microbial properties (respiration, biomass, community composition), and nematode abundance. Fast- and slow-growing plant communities did not differ in above- and belowground biomass. However, fast-and slow-growing plant communities created distinct soil bacterial communities, whereas soil fungal communities differed most in 100% forb communities compared to other forb:grass ratio mixtures. Moreover, soil nitrate availability was higher after two years of plant growth, whereas the opposite was true for soil ammonium concentrations. Furthermore, total nematodes and especially bacterial-feeding nematodes were more abundant after two years of plant growth. Our results show that plant community composition is a driving factor in soil microbial community assembly and that the duration of plant growth plays a crucial role in the establishment of plant community and functional group composition effects on abiotic and biotic soil ecosystem functioning under natural field conditions.</p>
Plant communities, grazing intensity, soil properties and decomposers in grasslands across elevation in the Eastern Carpathians in Ukraine
<p>This data set contains information on plant community properties, grazing intensity, elevation, soil properties and density of soil decomposers collected in 2006 and 2007 from the 31 semi-natural grasslands exposed to cattle grazing along elevation gradient at large topographic scale ranging from the Carpathian Mountains, across the adjacent foothills to the plain areas. Plant community properties are represented by the following variables for each of the 31 study grassland: number of species (species number 100 m<sup>-2</sup>), number of functional groups 100 m<sup>-2 </sup>(that is, legumes, grasses, rushes and sedges, and non-legume forbs), proportion of undesirable weeds (%), number of species of legumes (species number 100 m<sup>-2</sup>), number of species of grasses (species number 100 m<sup>-2</sup>), number of species of rushes and sedges (species number 100 m<sup>-2</sup>), and number of non-legume forbs (species number 100 m<sup>-2</sup>). Grazing intensity is measured as cattle density (livestock units h<sup>-1</sup>). Soil properties are represented for each 31 study grassland by bare soil exposure (%) , soil organic carbon content (%), and soil pH. Density of soil decomposers are represented by biomass of earthworms g m<sup>-2</sup> and abundance of soil microorganisms cells × 10<sup>8</sup> g (dry soil)<sup>-1</sup>. Plant community composition is based on individual species' canopy cover. This dataset also contain information on the following plant traits for each plant species (n=175 species) found across the 31 study pastures across 2006 and 2007 sampling years: family of the plant species, belonging to legumes, grasses, rushes and sedges, non-legume forbs, and undesirable weeds. All data are averages across the two sampling years. </p>

Catchment properties and the photosynthetic trait composition of freshwater plant communities
Unlike in land plants, photosynthesis in many aquatic plants relies on bicarbonate in addition to carbon dioxide (CO2) to compensate for the low diffusivity and potential depletion of CO2 in water. Concentrations of bicarbonate and CO2 vary greatly with catchment geology. In this study, we investigate whether there is a link between these concentrations and the frequency of freshwater plants possessing the bicarbonate use trait. We show, globally, that the frequency of plant species with this trait increases with bicarbonate concentration. Regionally, however, the frequency of bicarbonate use is reduced at sites where the CO2 concentration is substantially above the air equilibrium, consistent with this trait being an adaptation to carbon limitation. Future anthropogenic changes of bicarbonate and CO2 concentrations may alter the species compositions of freshwater plant communities.

Data from: Relationships between plant traits, soil properties and carbon fluxes differ between monocultures and mixed communities in temperate grassland
1. The use of plant traits to predict ecosystem functions has been gaining growing attention. Aboveground plant traits, such as leaf nitrogen (N) content and specific leaf area (SLA), have been shown to strongly relate to ecosystem productivity, respiration, and nutrient cycling. Further, increasing plant functional trait diversity has been suggested as a possible mechanism to increase ecosystem carbon (C) storage. However, it is uncertain whether belowground plant traits can be predicted by aboveground traits, and if both above- and belowground traits can be used to predict soil properties and ecosystem-level functions. 2. Here, we used two adjacent field experiments in temperate grassland to investigate if above- and belowground plant traits are related, and whether relationships between plant traits, soil properties and ecosystem C fluxes (i.e., ecosystem respiration and net ecosystem exchange) measured in potted monocultures could be detected in mixed field communities. 3. We found that certain shoot traits (e.g., shoot N and C, and leaf dry matter content) were related to root traits (e.g., root N, root C:N, and root dry matter content) in monocultures, but such relationships were either weak or not detected in mixed communities. Some relationships between plant traits (i.e., shoot N, root N and/or shoot C:N) and soil properties (i.e., inorganic N availability and microbial community structure) were similar in monocultures and mixed communities, but they were more strongly linked to shoot traits in monocultures and root traits in mixed communities. Structural equation modelling showed that above- and belowground traits and soil properties improved predictions of ecosystem C fluxes in monocultures, but not in mixed communities on the basis of community-weighted mean traits. 4. Synthesis: Our results from a single grassland habitat detected relationships in monocultures between above- and belowground plant traits, and between plant traits, soil properties and ecosystem C fluxes. However, these relationships were generally weaker or different in mixed communities. Our results demonstrate that while plant traits can be used to predict certain soil properties and ecosystem functions in monocultures, they are less effective for predicting how changes in plant species composition influence ecosystem functions in mixed communities.
